Clintonia uniflora. Clintonia uniflora, commonly known as bride's bonnet, queen's cup, or bead lily, is a species of flowering plant in the lily family Liliaceae. The specific epithet "uniflora" means "one-flowered", a characteristic that distinguishes this species from others in the genus "Clintonia". For this reason, it is also known as the single-flowered clintonia.## Description."Clintonia uniflora" is a perennial herbaceous plant that spreads by means of underground rhizomes. It is the smallest plant in the genus, only 15 to 25 (cm) tall. It has two or three leaves located at the base of a hairy stem. Each leaf is 2.5 to 6.5.

Clintonia uniflora. (cm) wide and 8 to 20 (cm) long. A plant typically bears a single flower but occasionally there will be an inflorescence of two flowers. The small flower has six white tepals, each approximately 2 (cm) long, and six protruding white stamens with pollen-dusted anthers. After pollination, the flower is replaced by a round blue berry approximately 1 (cm) in diameter.## Taxonomy.In 1829, Josef August Schultes described the plant variety "Smilacina borealis" var. "uniflora", which was later segregated into species "Smilacina uniflora". The latter was to become a synonym for "Clintonia uniflora", first described by Carl Sigismund Kunth in 1850.##.

Clintonia uniflora. Distribution."Clintonia uniflora" is native to western North America, from southern Alaska to central California, extending eastward into southwestern Alberta and northwestern Montana. It prefers cool montane coniferous forests, typically at elevations from 3000 to 5000 (feet)."C. uniflora" occurs in many forest types but it prefers a cool moist coniferous forest consisting of western red cedar ("Thuja plicata"), western hemlock ("Tsuga heterophylla"), grand fir ("Abies grandis"), subalpine fir ("Abies lasiocarpa"), and Pacific silver fir ("Abies amabilis"). It is also associated with western white pine ("Pinus monticola"), Alaska cedar ("Chamaecyparis nootkatensis"), and noble fir ("Abies procera"). Companion species in the understory include.

Clintonia uniflora. threeleaf foamflower ("Tiarella trifoliata"), twinflower ("Linnaea borealis"), and Canadian bunchberry ("Cornus canadensis").The range of "C. uniflora" overlaps with that of "C. andrewsiana" in Humboldt County and Del Norte County in northwestern California and Curry County in southwestern Oregon, but the two species are readily distinguished by their overall size and their flowers. "C. uniflora" has a single flower with white tepals while "C. andrewsiana" has multiple flowers arranged in one or more umbels. The tepals of the latter are a deep claret red.## Ecology."Clintonia uniflora" is a perennial geophyte that can live up to 30 years (or more). The plant.

Clintonia uniflora. flowers between late May and July, and thereafter the fruit matures from late July to September. Citizen scientists observe flowering plants uniformly throughout June and July.The plant is not considered palatable but it is of at least minor importance as food for some wildlife species including birds, elk, and deer. Frugivorous birds are the only reported dispersers of the seeds, which remain viable in the ground for at least a couple of years.## Uses.The indigenous peoples of the Pacific Northwest, including the Nuxalk, the Cowlitz, and the Haisla peoples, used the plant as a dermatological aid and eye medicine.

Lettuce. Lettuce ("Lactuca sativa") is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce (asparagus lettuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally.

Lettuce. appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century, cultivars were described that can still be found in modern gardens.Generally grown as a hardy annual, lettuce is easily cultivated, although it requires relatively low temperatures to prevent it from flowering quickly. It can be plagued by numerous nutrient deficiencies, as well as insect and mammal pests, and fungal and bacterial diseases. "L. sativa" crosses easily within the species and with some other species within the genus "Lactuca". Although this trait can be a.

Lettuce. problem to home gardeners who attempt to save seeds, biologists have used it to broaden the gene pool of cultivated lettuce varieties.Lettuce is a rich source of vitamin K and vitamin A, and a moderate source of folate and iron. Contaminated lettuce is often a source of bacterial, viral, and parasitic outbreaks in humans, including "E. coli" and "Salmonella".## Taxonomy and etymology."Lactuca sativa" is a member of the "Lactuca" (lettuce) genus and the Asteraceae (sunflower or aster) family. The species was first described in 1753 by Carl Linnaeus in the second volume of his "Species Plantarum". Synonyms for "L. sativa.

Lettuce. include "Lactuca scariola" "sativa", "L. scariola" "integrata" and "L. scariola" "integrifolia". "L. scariola" is itself a synonym for "L. serriola", the common wild or prickly lettuce. "L. sativa" also has many identified taxonomic groups, subspecies and varieties, which delineate the various cultivar groups of domesticated lettuce. Lettuce is closely related to several "Lactuca" species from southwest Asia; the closest relationship is to "L. serriola", an aggressive weed common in temperate and subtropical zones in much of the world.The Romans referred to lettuce as ( meaning "dairy" in Latin), an allusion to the white substance, latex, exuded by cut stems. The.

Lettuce. name "Lactuca" has become the genus name, while (meaning "sown" or "cultivated") was added to create the species name. The current word "lettuce", originally from Middle English, came from the Old French or , which derived from the Roman name. The name "romaine" came from the variety of lettuce grown in the Roman papal gardens, while "cos", another term for romaine lettuce, came from the earliest European seeds of the type from the Greek island of Kos, a center of lettuce farming in the Byzantine period.## Description.Lettuce's native range spreads from the Mediterranean to Siberia, although it has been transported.

Lettuce. cannot be successfully frozen, canned or dried and must be eaten fresh. In spite of its high water content, traditionally grown lettuce has a low water footprint, with 237 liters of water required for each kilogram of lettuce produced. Hydroponic growing methods can reduce this water consumption by nearly two orders of magnitude.Lettuce varieties will cross with each other, making spacing of 1.5 to 6 (m) between varieties necessary to prevent contamination when saving seeds. Lettuce will also cross with "Lactuca serriola" (wild lettuce), with the resulting seeds often producing a plant with tough, bitter leaves. Celtuce, a lettuce variety.

Lettuce. grown primarily in Asia for its stems, crosses easily with lettuces grown for their leaves. This propensity for crossing, however, has led to breeding programs using closely related species in "Lactuca", such as "L. serriola", "L. saligna", and "L. virosa", to broaden the available gene pool. Starting in the 1990s, such programs began to include more distantly related species such as "L. tatarica".Seeds keep best when stored in cool conditions, and, unless stored cryogenically, remain viable the longest when stored at -20 (C); they are relatively short lived in storage. At room temperature, lettuce seeds remain viable for only a.

Lettuce. insects and disease and can make harvesting more difficult. Herbicides are often used to control weeds in commercial production. However, this has led to the development of herbicide-resistant weeds in lettuce cultivation.## Production.In 2020, world production of lettuce (report combined with chicory) was 28 million tonnes, with China alone producing 14.3 million tonnes or 52% of the world total (see table).Lettuce is the only member of the genus "Lactuca" to be grown commercially. Although China is the top world producer of lettuce, the majority of the crop is consumed domestically. Spain is the world's largest exporter of lettuce, with the.

Lettuce. lactucarium or "lettuce opium". Although the standard definition of lactucarium requires its production from "Lactuca virosa" or "wild lettuce", it was recognized that smaller quantities of lactucarium could be produced in a similar way from "Lactuca sativa" and "Lactuca canadensis" var. "elongata", and that lettuce-opium obtained from "Lactuca serriola" or "Lactuca quercina" was of superior quality.Romaine lettuce is one of the symbolic items on the Jewish Passover Seder plate as a bitter herb (maror).Some American settlers claimed that smallpox could be prevented through the ingestion of lettuce, and an Iranian belief suggested consumption of the seeds when afflicted with typhoid.

Kon-Tiki expedition. The "Kon-Tiki" expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl. The raft was named "Kon-Tiki" after the Inca god Viracocha, for whom "Kon-Tiki" was said to be an old name. "" is also the name of Heyerdahl's book, the Academy Award–winning 1950 documentary film chronicling his adventures, and the 2012 dramatized feature film nominated for the Academy Award for Best Foreign Language Film.Heyerdahl believed that people from South America could have reached Polynesia during pre-Columbian times. His aim in mounting the "Kon-Tiki.

Kon-Tiki expedition. expedition was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. Although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives, Heyerdahl argued they were incidental to the purpose of proving that the raft itself could make the journey. This idea has recently received support from statistical analysis of genetic evidence of contact between South America and Polynesia.Heyerdahl's full hypothesis of a South American origin of the Polynesian peoples is generally rejected by.

Kon-Tiki expedition. scientists today. Most archaeological, linguistic, cultural, and genetic evidence tends to support a western origin for Polynesians, from Island Southeast Asia, using sophisticated multihull sailing technologies and navigation techniques during the Austronesian expansion. However, there is evidence of some gene flow from South America to Easter Island. In 2020 some researchers published research confirming a wider impact on genetic and cultural elements in Polynesia due to South American contacts. The "Kon-Tiki" expedition was funded by private loans, along with donations of equipment from the United States Army. Heyerdahl and a small team went to Peru, where, with the help of.

Kon-Tiki expedition. dockyard facilities provided by the Peruvian authorities, they constructed the raft out of balsa logs and other native materials in an indigenous style as recorded in illustrations by Spanish conquistadores. The trip began on April 28, 1947. Heyerdahl and five companions sailed the raft for 101 days over 6,900 km (4,300 miles) across the Pacific Ocean before smashing into a reef at Raroia in the Tuamotus on August 7, 1947. The crew made successful landfall and all returned safely.Thor Heyerdahl's book about his experience became a bestseller. It was published in Norwegian in 1948 as "The Kon-Tiki Expedition: By Raft.

Kon-Tiki expedition. Across the South Seas", later reprinted as "Kon-Tiki: Across the Pacific in a Raft". It appeared with great success in English in 1950, also in many other languages. A documentary motion picture about the expedition, also called "Kon-Tiki", was produced from a write-up and expansion of the crew's filmstrip notes and won an Academy Award in 1951. It was directed by Heyerdahl and edited by Olle Nordemar. The voyage was also chronicled in the documentary TV-series "The Kon-Tiki Man: The Life and Adventures of Thor Heyerdahl", directed by Bengt Jonson.The original "Kon-Tiki" raft is now on display in the Kon-Tiki.

Kon-Tiki expedition. Museum at Bygdøy in Oslo.## Crew."Kon-Tiki" had a six-man crew, all of whom were Norwegian except for Bengt Danielsson, a Swede. Thor Heyerdahl (1914–2002) was the expedition leader. He was also the author of the book of the expedition and the narrator of the story. Heyerdahl had studied the ancient people of South America and Polynesia and believed that there was a link between the two. Erik Hesselberg (1914–1972) was the navigator and artist. He painted the large Kon-Tiki figure on the raft's sail. His children's book "Kon-Tiki and I" appeared in Norwegian in 1949 and has since been published.

Kon-Tiki expedition. in more than 15 languages. Bengt Danielsson (1921–1997) took on the role of steward, in charge of supplies and daily rations. Danielsson was a Swedish sociologist interested in human migration theory. He also served as translator, as he was the only member of the crew who spoke Spanish. He was also a voracious reader; his box aboard the raft contained many books. Knut Haugland (1917–2009) was a radio expert, decorated by the British in World War II for actions in the Norwegian heavy water sabotage that stalled what were believed to be Germany's plans to develop an atomic bomb. Haugland.

Kon-Tiki expedition. was the last surviving crew member; he died on Christmas Day, 2009 at the age of 92. Torstein Raaby (1918–1964) was also in charge of radio transmissions. He gained radio experience while hiding behind German lines during WWII, spying on the German battleship "Tirpitz". His secret radio transmissions eventually helped guide in Allied bombers to sink the ship. Herman Watzinger (1910–1986) was an engineer whose area of expertise was in technical measurements. He was the first to join Heyerdahl for the trip. He collected and recorded all sorts of data on the voyage. Much of what he recorded, such as.

Kon-Tiki expedition. weather data, was sent back to various people, since this area of the ocean was largely unstudied.The expedition also carried a pet parrot named Lorita.## Construction.The main body of the float was composed of nine balsa tree trunks up to 45 (ft) long, 2 (ft) in diameter, lashed together with 1+1/4 (in) hemp ropes. Cross-pieces of balsa logs 18 (ft) long and 1 (ft) in diameter were lashed across the logs at 3 (ft) intervals to give lateral support. Pine splashboards clad the bow, and lengths of pine 1 (in) thick and 2 (ft) wide were wedged between the balsa.

Kon-Tiki expedition. logs and used as centreboards.The main mast was made of lengths of mangrove wood lashed together to form an A-frame 29 (ft) high. Behind the main-mast was a cabin of plaited bamboo 14 (ft) long and 8 (ft) wide, about 4 - 5 (ft) high and roofed with banana leaf thatch. At the stern was a 19 (ft) long steering oar of mangrove wood, with a blade of fir. The main sail was 15 by 18 (ft) on a yard of bamboo stems lashed together. Photographs also show a top-sail above the main sail, and also a mizzen-sail, mounted at.

Kon-Tiki expedition. the stern.The raft was partially decked in split bamboo. The main spars were a laminate of wood and reeds and Heyerdahl tested more than twenty different composites before settling on one that proved an effective compromise between bulk and torsional rigidity. No metal was used in the construction.## Supplies."Kon-Tiki" carried 275 (USgal) of drinking water in 56 water cans, as well as a number of sealed bamboo rods. The purpose stated by Heyerdahl for carrying modern and ancient containers was to test the effectiveness of ancient water storage. For food "Kon-Tiki" carried 200 coconuts, sweet potatoes, bottle gourds and other.

Kon-Tiki expedition. assorted fruit and roots. The U.S. Army Quartermaster Corps provided field rations, tinned food and survival equipment. In return, the "Kon-Tiki" explorers reported on the quality and utility of the provisions. They also caught plentiful numbers of fish, particularly flying fish, "dolphin fish", yellowfin tuna, bonito and shark.Heyerdahl and crew were equipped with water-tight sports wristwatches manufactured by Swiss watchmaking firm Eterna. After the journey, Eterna decided to brand their sports watches as "Kon-Tiki".## Communications.The expedition carried an amateur radio station with the call sign of LI2B operated by former World War II Norwegian resistance radio operators Knut Haugland and.

Kon-Tiki expedition. Torstein Raaby. Haugland and Raaby maintained regular communication with a number of American, Canadian, and South American stations that relayed "Kon Tiki's" status to the Norwegian Embassy in Washington, D.C. On August 5, Haugland made contact with a station in Oslo, Norway, 10000 (mi) away."Kon Tiki's" transmitters were powered by batteries and a hand-cranked generator and operated on the 40, 20, 10, and 6-meter bands. Each unit was water resistant, used 2E30 vacuum tubes, and provided approximately 6 watts of RF output; the equivalent of a small flashlight. Two British 3-16 MHz Mark II transmitters were also carried on board,.

Kon-Tiki expedition. as was a VHF transmitter for communicating with aircraft and a hand-cranked survival radio of the Gibson Girl type for 500 and 8280 kHz.The radio receiver used throughout the voyage, a National Radio Company NC-173, once required a thorough drying out after being soaked when landing in Raratonga. The crew once used a hand-cranked emergency transmitter to send out an "all well, all well" message "just in time to head off a massive rescue attempt".The call sign LI2B was used by Heyerdahl again in 1969–70, when he built a papyrus reed raft and sailed from Morocco to Barbados in an.

To avoid coastal traffic it was initially towed 50 (mi) out by the Peruvian Navy fleet tug "Guardian Rios", then sailed roughly west carried along on the Humboldt Current.On 2 July Heyerdahl writes about an encounter with a rogue wave; in his book he describes a "Three Sister" phenomenon: "During a night-shift with quiet seas appears an 'abnormal huge wave' followed by two more waves. The raft is being swept up and.

Kon-Tiki expedition. down and is covered in water." After the three waves he describes the sea as quiet as before.The crew's first sight of land was the atoll of Puka-Puka on July 30. On August 4, the 97th day after departure, "Kon-Tiki" reached the Angatau atoll. The crew made brief contact with the inhabitants of Angatau Island, but were unable to land safely. Calculations made by Heyerdahl before the trip had indicated that 97 days was the minimum amount of time required to reach the Tuamotus, so the encounter with Angatau showed that they had made good time.On August 7, the voyage.

Kon-Tiki expedition. ended when the raft struck a reef and was then beached on an uninhabited islet off Raroia atoll in the Tuamotus. The team had travelled a distance of around 6980 (km) in 101 days, at an average speed of 1.5 (kn).After spending a number of days alone on the islet, the crew was greeted by men from a village on a nearby island who arrived in canoes, having seen washed-up flotsam from the raft. The crew were taken back to the native village, where they were feted with traditional dances and other festivities. Finally the crew were taken off Raroia.

Kon-Tiki expedition. to Tahiti by the French schooner "Tamara", with the salvaged "Kon-Tiki" in tow.## Anthropology.The basis of the "Kon-Tiki" expedition was pseudoscientific, racially controversial, and has not gained acceptance among scientists (even prior to the voyage). Heyerdahl believed that the original inhabitants of Easter Island (and the rest of Polynesia) were the "Tiki people", a race of "white bearded men" who supposedly originally sailed from Peru. He described these "Tiki people" as being a sun-worshipping fair-skinned people with blue eyes, fair or red hair, tall statures, and beards. He further said that these people were originally from the Middle East, and.

Kon-Tiki expedition. had crossed the Atlantic earlier to found the great Mesoamerican civilizations. By 500 CE, a branch of these people were supposedly forced out into Tiahuanaco where they became the ruling class of the Inca Empire and set out to voyage into the Pacific Ocean under the leadership of "Con Ticci Viracocha".He argued that the monumental statues known as moai resembled sculptures more typical of pre-Columbian Peru than any Polynesian designs. He believed that the Easter Island myth of a power struggle between two peoples called the Hanau epe and Hanau momoko was a memory of conflicts between the original inhabitants.

Kon-Tiki expedition. of the island and a later wave of Native Americans from the Northwest coast, eventually leading to the annihilation of the Hanau epe and the destruction of the island's culture and once-prosperous economy. Heyerdahl described these later migrants as "Maori-Polynesians" who were supposedly Asians who crossed over the Bering land bridge into Northwest America before sailing westward towards Polynesia (the westward direction is because he refused to accept that Polynesians were capable of sailing against winds and currents). He associated them with the Tlingit and Haida peoples and characterized them as "inferior" to the Tiki people.Heyerdahl's hypothesis was part of.

Kon-Tiki expedition. early Eurocentric hyperdiffusionism and the westerner disbelief that (non-white) "stone-age" peoples with "no math" could colonize islands separated by vast distances of ocean water, even against prevailing winds and currents. He rejected the highly skilled voyaging and navigating traditions of the Austronesian peoples and instead argued that Polynesia was settled from boats following the wind and currents for navigation from South America. As such, the "Kon-Tiki" was deliberately a primitive raft and unsteerable, in contrast to the sophisticated outrigger canoes and catamarans of the Austronesian people.Heyerdahl's hypothesis of Polynesian origins is overwhelmingly rejected by scientists today. Archaeological, linguistic, cultural, and.

Kon-Tiki expedition. genetic evidence all support a western origin (from Island Southeast Asia) for Polynesians via the Austronesian expansion. "Drift voyaging" from South America was also deemed "extremely unlikely" in 1973 by computer modeling, although is in contrast with recent genetic analysis. The 1976 voyage of the "Hōkūleʻa", a performance-accurate replica of a Polynesian double-hulled "wa'a kaulua" voyaging canoe, from Hawaiʻi to Tahiti was partly a demonstration to prove that Heyerdahl was wrong. The "Hōkūleʻa" sailed against prevailing winds and exclusively used wayfinding and celestial Polynesian navigation techniques (unlike the modern equipment and charts of the "Kon-Tiki"). "Hōkūleʻa" also remains fully operational,.

Kon-Tiki expedition. and has since completed ten other voyages, including a three-year circumnavigation of the planet from 2014 to 2017, with other sister ships.Historians today consider that the Polynesians from the west were the original inhabitants and that the story of the Hanau epe is either pure myth, or a memory of internal tribal or class conflicts. In 2011, Erik Thorsby of the University of Oslo presented DNA evidence to the Royal Society which, whilst agreeing with the west origin, also identified a distinctive but smaller genetic contribution from South America. This result was questioned in 2012 because of the possibility of.

Kon-Tiki expedition. contamination by South Americans after European contact with the islands. In 2014, further work by a team including Anna-Sapfo Malaspinas (from the Natural History Museum of Denmark) analysed the genomes of 27 native Rapa Nui people and found that their DNA was on average 76 percent Polynesian, 8 percent Native American and 16 percent European. Analysis showed that "although the European lineage could be explained by contact with white Europeans after the island was 'discovered' in 1722 by Dutch sailors, the South American component was much older, dating to between about 1280 and 1495, soon after the island was first.

Kon-Tiki expedition. colonised by Polynesians in around 1200." Genetic analysis of Polynesians and Native South Americans, published in "Nature" in July 2020, has revealed that several eastern Polynesian populations have signs of an ancient genetic signature that originated from Native South American people. An initial admixture event between Native South Americans and Polynesians, discovered by statistical analysis, took place around 1150–1230 CE.## Later recreations of "Kon-Tiki".## "Seven Little Sisters".In 1954, William Willis sailed alone on a raft "Seven Little Sisters" from Peru to American Samoa, successfully completing the journey. He sailed 6,700 (mi), which was 2,200 (mi) farther than "Kon-Tiki". In a.

Kon-Tiki expedition. second great voyage ten years later, he rafted 7457 (mi) from South America to Australia with a metal raft "Age Unlimited".## "Kantuta".In 1955, the Czech explorer and adventurer Eduard Ingris attempted to recreate the "Kon-Tiki" expedition on a balsa raft called "Kantuta". His first expedition, "Kantuta I", took place in 1955–1956 and led to failure. In 1959, Ingris built a new balsa raft, "Kantuta II", and tried to repeat the previous expedition. The second expedition was a success. Ingris was able to cross the Pacific Ocean on the balsa raft from Peru to Polynesia.## "Tahiti-Nui".A French seafarer, Éric de Bisschop,.

Kon-Tiki expedition. committed himself in a project he had had for some years: he built a Polynesian raft in order to cross the eastern Pacific Ocean from Tahiti to Chile (contrary to Thor Heyerdahl's crossing); the "Tahiti-Nui" left Papeete with a crew of five on November 8, 1956. When near the Juan Fernández Islands (Chile) in May 1957, the raft was in a very poor state and they asked for a towing, but it was damaged during the operation and had to be abandoned, but they were able to preserve all the equipment that had been aboard.## "Tahiti-Nui II".A second "Tahiti-Nui" was.

Kon-Tiki expedition. built in Constitución, Chile, leaving on April 13, 1958, towards Callao, then towards the Marquesas. It missed its target and after four months, the raft began to sink. The crew built a new smaller raft, the "Tahiti Nui III", in the ocean out of the more buoyant parts of the "Tahiti Nui II". They were swept towards Cook Islands where on August 30, the raft went aground and was wrecked at Rakahanga atoll. Éric de Bisschop died in this accident.## "Tangaroa" (1965).A Peruvian expedition led by Carlos Caravedo crossed the Pacific Ocean in 1965 in 115 days in a raft.

Kon-Tiki expedition. named "Tangaroa", of which 18 days were used by the crew to cross Tuamotus, the Tuamotu Archipielago, making "Tangaroa" the only raft that has managed to cross that dangerous archipelago of French Polynesia by its own means. On November 18, 1965, the "Tangaroa" ended its journey on the Fakarava island. Fakarava is where the "Tangaroa" is currently preserved.## Las Balsas.The 1973 Las Balsas expedition was the first (and so far only) multiple-raft crossing of the Pacific Ocean in recent history. It is the longest-known raft voyage in history. The expedition was led by Spaniard Vital Alsar, who, in 1970, led.

Kon-Tiki expedition. the La Balsa expedition, only on that occasion with one raft and three companions. The crossing was successful and, at the time, the longest raft voyage in history, until eclipsed in 1973 by Las Balsas. The purpose of the 1973 expedition was three-fold: (1) to prove that the success of 1970 was no accident, (2) to test different currents in the sea, which Alsar maintained ancient mariners knew as modern humans know road maps, and (3) to show that the original expeditions, directed perhaps toward trade or colonisation, may have consisted of small fleets of balsa rafts.## "Tangaroa" (2006).In 2006,.

Kon-Tiki expedition. the Tangaroa Expedition recreated the "Kon-Tiki" voyage using a newly built raft, the "Tangaroa", named after the Māori sea-god Tangaroa. Tangaroa's six-man crew was led by Norwegian Torgeir Higraff and included Olav Heyerdahl, grandson of Thor Heyerdahl, Bjarne Krekvik (captain), Øyvin Lauten (executive officer), Swedish Anders Berg (photographer) and Peruvian Roberto Sala. "Tangaroa" was launched on the same day that "Kon-Tiki" had been—April 28—and it reached its destination on July 7, which was 30 days faster than Heyerdahl's Kon-Tiki which had taken 101 days for the voyage. Tangaroa's speed was credited to the proper use of guaras (centerboards).## "An-Tiki".On January.

The expedition was piloted by four men, aged from 56 to 84 years, led by Anthony Smith. The trip was designed to commemorate the journey in an open boat of survivors from the British steamship "Anglo-Saxon", sunk by the German cruiser "Widder" in 1940. The raft ended its voyage in the Caribbean island of St Maarten, completing its trip to Eleuthera in the following year with Smith and a new.

Expedition "Kon-Tiki2" got its name because it had 2 crews from many nations: Norway, Russia, UK, Mexico, New Zealand, Sweden, and Peru. It sought to double down on Heyerdahl's voyage by sailing two rafts from South America to Polynesia and then back. Expedition leader was Torgeir Higraff from Tangaroa Expedition (2006). Øyvin Lauten and Kari Skår Dahl were captains on the first leg, while Signe Meling and Ola Borgfjord were captains on the second leg. The raft reached.

Aqua-Lung. Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus (or "scuba") to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a twin-hose diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: the engineer Émile Gagnan and the Naval Lieutenant (French: "lieutenant de vaisseau") Jacques Cousteau. It allowed Cousteau and Gagnan to film and explore underwater more easily.The invention revolutionised autonomous underwater diving by providing a compact, reliable system capable of a greater depth range and endurance than its precursors, and was a.

Aqua-Lung. Bernard Piel"). One of their apparatuses went to Émile Gagnan, an engineer employed by the Air Liquide company. Gagnan miniaturized and adapted it to gas generators in response to a fuel shortage, which was a consequence of German requisitioning. Gagnan's boss, Henri Melchior, knew that his son-in-law Jacques-Yves Cousteau was looking for an automatic demand regulator to increase the useful endurance of the underwater breathing apparatus invented by Commander Yves le Prieur, so he introduced Cousteau to Gagnan in December 1942. On Cousteau's initiative, the Gagnan regulator was modified for use in diving. Cousteau and Gagnan were issued a patent.

Aqua-Lung. French company.Air Liquide held the patent on the original "Aqualung" (also written as "Aqua-Lung" or "Aqua Lung") until the patent expired sometime around 1960 to 1963. The term "Aqualung", as far as is known, first appeared in print on page 3 of Jacques-Yves Cousteau's first book, "The Silent World", in 1953. Public use of the word "aqualung", and public interest in Aqualungs and scuba diving, were started around 1953 in English-speaking counties by a National Geographical Society Magazine article about Cousteau's underwater archaeological expedition to Grand Congloué. In France, aqualung diving was popularized by Cousteau's movie "Épaves", while his book.

Baltimore oriole. The Baltimore oriole (Icterus galbula) is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17th century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole, "Icterus bullockii", led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.The Baltimore oriole is.

Baltimore oriole. the state bird of Maryland. It is also the namesake and mascot for the Baltimore Orioles baseball team.## Taxonomy.The Baltimore oriole was one of the many bird species originally described by Carl Linnaeus in the 1758 10th edition of his "Systema Naturae", where it was given the binomial name of "Coracias galbula".Like all New World orioles, this species is named after an unrelated, physically similar family found in the Old World: the Oriolidae. "Oriole" ultimately derives from Latin "aureolus", "golden". The genus name "Icterus" is from Ancient Greek "ikteros", a yellow bird, usually taken to be the Eurasian golden oriole,.

Baltimore oriole. larger perches. Baltimore orioles are also fond of halved oranges, grape jelly and, in their winter quarters, the red arils of gumbo-limbo ("Bursera simaruba").

Banksia. Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. "Banksias" range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.Heavy producers of nectar, "banksias" are a vital part of the food chain in the Australian bush. They are an important food source for all sorts of.

Banksia. nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangered.## Description.Banksias grow as trees or woody shrubs. Trees of the largest species, "B. integrifolia" (coast banksia) and "B. seminuda" (river banksia), often grow over 15 metres tall, some even grow to standing 30 metres tall. "Banksia" species that grow as shrubs are usually erect, but there are.

Banksia. several species that are prostrate, with branches that grow on or below the soil.The leaves of "Banksia" vary greatly between species. Sizes vary from the narrow, 1– centimetre long needle-like leaves of "B. ericifolia" (heath-leaved banksia), to the very large leaves of "B. grandis" (bull banksia), which may be up to 45 centimetres long. The leaves of most species have serrated edges, but a few, such as "B. integrifolia", do not. Leaves are usually arranged along the branches in irregular spirals, but in some species they are crowded together in whorls. Many species have differing juvenile and adult leaves (e.g.,.

Banksia. "Banksia integrifolia" has large serrated juvenile leaves).The flowers are arranged in flower spikes or capitate flower heads. The character most commonly associated with "Banksia" is the flower spike, an elongated inflorescence consisting of a woody axis covered in tightly packed pairs of flowers attached at right angles. A single flower spike generally contains hundreds or even thousands of flowers; the most recorded is around 6000 on inflorescences of "B. grandis". Not all "Banksia" have an elongate flower spike, however: the members of the small "Isostylis" complex have long been recognised as "banksias" in which the flower spike has been reduced.

Banksia. to a head; and recently the large genus "Dryandra" has been found to have arisen from within the ranks of "Banksia", and sunk into it as "B." ser. "Dryandra". They similarly have capitate flower heads rather than spikes."Banksia" flowers are usually a shade of yellow, but orange, red, pink and even violet flowers also occur. The colour of the flowers is determined by the colour of the perianth parts and often the style. The style is much longer than the perianth, and is initially trapped by the upper perianth parts. These are gradually released over a period of days, either.

Banksia. from top to bottom or from bottom to top. When the styles and perianth parts are different colours, the visual effect is of a colour change sweeping along the spike. This can be most spectacular in "B. prionotes" (acorn banksia) and related species, as the white inflorescence in bud becomes a brilliant orange. In most cases, the individual flowers are tall, thin saccate (sack-shaped) in shape.Occasionally, multiple flower spikes can form. This is most often seen in "Banksia marginata" and "B. ericifolia" "(pictured right)".As the flower spikes or heads age, the flower parts dry up and may turn shades of.

Banksia. orange, tan or dark brown colour, before fading to grey over a period of years. In some species, old flower parts are lost, revealing the axis; in others, the old flower parts may persist for many years, giving the fruiting structure a hairy appearance. Old flower spikes are commonly referred to as "cones", although they are not technically cones according to the botanical definition of the term: cones only occur in conifers and cycads.Despite the large number of flowers per inflorescence, only a few of them ever develop fruit, and in some species a flower spike will set no fruit.

Banksia. at all. The fruit of "Banksia" is a woody follicle embedded in the axis of the inflorescence. In many species, the resulting structure is a massive woody structure commonly called a cone. Each follicle consists of two horizontal valves that tightly enclose the seeds. The follicle opens to release the seed by splitting along the suture. In some species, each valve splits too. In some species the follicles open as soon as the seed is mature, but in most species most follicles open only after stimulated to do so by bushfire. Each follicle usually contains one or two small seeds,.

Banksia. each with a wedge-shaped papery wing that causes it to spin as it falls to the ground.## Taxonomy.Specimens of "Banksia" were first collected by Sir Joseph Banks and Dr Daniel Solander, naturalists on the "Endeavour" during Lieutenant (later Captain) James Cook's first voyage to the Pacific Ocean. Cook landed on Australian soil for the first time on 29 April 1770, at a place that he later named Botany Bay in recognition of "the great quantity of plants Mr Banks and Dr Solander found in this place". Over the next seven weeks, Banks and Solander collected thousands of plant specimens, including.

Banksia. the first specimens of a new genus that would later be named "Banksia" in Banks' honour. Four species were present in this first collection: "B. serrata" (Saw Banksia), "B. integrifolia" (Coast Banksia), "B. ericifolia" (Heath-leaved Banksia) and "B. robur" (Swamp Banksia). In June the ship was careened at Endeavour River, where specimens of "B. dentata" (Tropical Banksia) were collected.The genus "Banksia" was finally described and named by Carolus Linnaeus the Younger in his April 1782 publication "Supplementum Plantarum"; hence the full name for the genus is ""Banksia" L.f.". Linnaeus placed the genus in class Tetrandra, order Monogynia of his father's.

Banksia. classification, and named it in honour of Banks. The name "Banksia" had in fact already been published in 1775 as "Banksia" J.R.Forst & G.Forst, referring to some New Zealand species that the Forsters had collected during Cook's second voyage. However Linnaeus incorrectly attributed the Forsters' specimens to the genus "Passerina", and therefore considered the name "Banksia" available for use. By the time Joseph Gaertner corrected Banks' error in 1788, "Banksia" L.f. was widely known and accepted, so Gaertner renamed "Banksia" J.R.Forst, & G.Forst to "Pimelea", a name previously chosen for the genus by Banks and Solander.The first specimens of a.

Banksia. "Dryandra" were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of "Dryandra ("now" Banksia) sessilis" (Parrotbush) and "D. ("now" Banksia) pellaeifolia". Upon Menzies' return to England, he turned his specimens over to Banks; as with most other specimens in Banks' library, they remained undescribed for many years. Robert Brown gave a lecture, naming the new genus "Dryandra" in.

Banksia. 1809, however Joseph Knight published the name "Josephia" before Brown published his paper with the description of "Dryandra". Brown ignored Knight's name, as did subsequent botanists.In 1891, Otto Kuntze, strictly applying the principle of priority, argued that "Pimelea" should revert to the name "Banksia" J.R.Forst & G.Forst. He proposed the new genus "Sirmuellera" to replaced "Banksia" L.f. and transferred its species to the new genus. This arrangement was largely ignored by Kuntze's contemporaries."Banksia" L.f. was formally conserved and "Sirmuellera" rejected in 1940."Banksia" belongs to the family Proteaceae, subfamily Grevilleoideae, and tribe Banksieae. There are around 170 species. The closest relatives.

Banksia. of "Banksia" are two genera of rainforest trees in North Queensland ("Musgravea" and "Austromuellera").## Subgeneric arrangement.Alex George arranged the genus into two subgenera—subgenus "Isostylis" (containing "B. ilicifolia", "B. oligantha" and "B. cuneata") and subgenus "Banksia" (containing all other species except those he considered dryandras)—in his 1981 monograph and 1999 treatment for the Flora of Australia series. He held that flower morphology was the key to relationships in the genus. Austin Mast and Kevin Thiele published the official merging of "Dryandra" within "Banksia" in 2007, recalibrating the genus into subgenus "Banksia" and subgenus "Spathulatae".## Distribution and habitat.All but one of the.

Banksia. living "Banksia" species are endemic to Australia. The exception is "B. dentata" (tropical banksia), which occurs throughout northern Australia, and on islands to the north including New Guinea and the Aru Islands. An extinct species, "B. novae-zelandiae", was found in New Zealand. The other species occur in two distinct geographical regions: southwest Western Australia and eastern Australia. Southwest Western Australia is the main centre of biodiversity; over 90% of all "Banksia" species occur only there, from Exmouth in the north, south and east to beyond Esperance on the south coast. Eastern Australia has far fewer species, but these include some.

Banksia. of best known and most widely distributed species, including "B. integrifolia" (coast banksia) and "B. spinulosa" (hairpin banksia). Here they occur from the Eyre Peninsula in South Australia right around the east coast up to Cape York in Queensland.The vast majority of "Banksia" are found in sandy or gravelly soils, though some populations of "B. marginata" (silver banksia) and "B. spinulosa" do occur on soil that is heavier and more clay-like. "B. seminuda" is exceptional for its preference for rich loams along watercourses.Most occur in heathlands or low woodlands; of the eastern species, "B. integrifolia" and "B. marginata" occur in.

Banksia. forests; many south-western species such as "B. grandis", "B. sphaerocarpa", "B. sessilis", "B. nobilis" and "B. dallanneyi" grow as understorey plants in jarrah ("Eucalyptus marginata"), wandoo ("E. wandoo") and karri ("E. diversicolor") forests, with "B. seminuda" being one of the forest trees in suitable habitat.Most species do not grow well near the coast, notable exceptions being the southern Western Australian species "B. speciosa", "B. praemorsa" and "B. repens". Only a few species, such as "B. rosserae" and "B. elderiana" (swordfish banksia), occur in arid areas. Most of the eastern Australian species survive in uplands, but only a few of the.

Banksia. Western Australian species native to the Stirling Ranges – "B. solandri", "B. oreophila", "B. brownii" and "B. montana" – survive at high altitudes.Studies of the south-western species have found the distribution of "Banksia" species to be primarily constrained by rainfall. With the exception of "B. rosserae", no species tolerates annual rainfall of less than 200 millimetres, despite many species surviving in areas that receive less than 400 millimetres. "Banksia" species are present throughout the region of suitable rainfall, with greatest speciation in cooler, wetter areas. Hotter, drier regions around the edges of its range tend to have fewer species with.

Banksia. larger distributions. The greatest species richness occurs in association with uplands, especially the Stirling Range.## Evolution and fossil record.There are many fossils of "Banksia". The oldest of these are fossil pollen between 65 and 59 million years old. There are fossil leaves between 59 and 56 million years old found in southern New South Wales. The oldest fossil cones are between 47.8 and 41.2 million years old, found in Western Australia. Although "Banksia" is now only native to Australia and New Guinea, there are fossils from New Zealand, between 21 and 25 million years old.Evolutionary scientists Marcell Cardillo and Renae.

Banksia. Pratt have proposed a southwest Australian origin for banksias despite their closest relatives being north Queensland rainforest species.## Ecology.Banksias are heavy producers of nectar, making them an important source of food for nectivorous animals, including honeyeaters and small mammals such as rodents, antechinus, honey possums, pygmy possums, gliders and bats. Many of these animals play a role in pollination of "Banksia". Various studies have shown mammals and birds to be important pollinators. In 1978 Carpenter observed that some banksias had a stronger odour at night, possibly to attract nocturnal mammal pollinators. Other associated fauna include the larvae of moths (such.

Banksia. as the Dryandra Moth) and weevils, which burrow into the "cones" to eat the seeds and pupate in the follicles; and birds such as cockatoos, who break off the "cones" to eat both the seeds and the insect larvae.A number of "Banksia" species are considered rare or endangered. These include "B. brownii" (feather-leaved banksia), "B. cuneata" (matchstick banksia), "B. goodii" (Good's banksia), "B. oligantha" (Wagin banksia), "B. tricuspis" (pine banksia), and "B. verticillata" (granite banksia).## Response to fire."Banksia" plants are naturally adapted to the presence of regular bushfires in the Australian landscape. About half of "Banksia" species are killed by.

Banksia. bushfire, but these regenerate quickly from seed, as fire also stimulates the opening of seed-bearing follicles and the germination of seed in the ground. The remaining species usually survive bushfire, either by resprouting from a woody base known as a lignotuber or, more rarely, epicormic buds protected by thick bark. In Western Australia, banksias of the first group are known as 'seeders' and the second group as 'sprouters'.Infrequent bushfires at expected intervals pose no threat, and are in fact beneficial for regeneration of "banksia" populations. However, too frequent bushfires can seriously reduce or even eliminate populations from certain areas, by.

Banksia. killing seedlings and young plants before they reach fruiting age. Many fires near urban areas are caused by arson, and thus the frequency is often much higher than fires would have been prior to human habitation. Furthermore, residents who live in areas near bushland may pressure local councils to burn areas near homes more frequently, to reduce fuel-load in the bush and thus reduce ferocity of future fires. Unfortunately there are often discrepancies in agreed frequency between these groups and conservation groups.## Dieback.Another threat to "Banksia" is the water mould "Phytophthora cinnamomi", commonly known as "dieback". Dieback attacks the roots.

Banksia. of plants, destroying the structure of the root tissues, "rotting" the root, and preventing the plant from absorbing water and nutrients. "Banksia"'s proteoid roots, which help it to survive in low-nutrient soils, make it highly susceptible to this disease. All Western Australian species are vulnerable, although most eastern species are fairly resistant.Vulnerable plants typically die within a few years of infection. In southwest Western Australia, where dieback infestation is widespread, infested areas of "Banksia" forest typically have less than 30% of the cover of uninfested areas. Plant deaths in such large proportions can have a profound influence on the makeup.

Banksia. of plant communities. For example, in southwestern Australia "Banksia" often occurs as an understorey to forests of jarrah ("Eucalyptus marginata"), another species highly vulnerable to dieback. Infestation kills both the jarrah overstorey and the original "Banksia" understorey, and over time these may be replaced by a more open woodland consisting of an overstorey of the resistant marri ("Corymbia calophylla"), and an understorey of the somewhat resistant "Banksia sessilis" (parrot bush).A number of species of "Banksia" are threatened by dieback. Nearly every known wild population of "B. brownii" shows some signs of dieback infection, which could possibly wipe it out within.

Banksia. years. Other vulnerable species include "B. cuneata", and "B. verticillata".Dieback is notoriously difficult to treat, although there has been some success with phosphite and phosphorous acid, which are currently used to inoculate wild "B. brownii" populations. However this is not without potential problems as it alters the soil composition by adding phosphorus. Some evidence suggests that phosphorous acid may inhibit proteoid root formation.Because dieback thrives in moist soil conditions, it can be a severe problem for banksias that are watered, such as in the cut flower industry and urban gardens.## Uses.## Gardening.Most of species are shrubs, only few of them.

Banksia. can be found as trees and they are very popular because of their size, the tallest species are: "B. integrifolia" having its subspecies "B. integrifolia" subsp. "monticola" notable for reaching the biggest size for the genus and it is the most frost tolerant in this genus, "B. seminuda", "B. littoralis", "B. serrata"; species that can grow as small trees or big shrubs: "B. grandis", "B. prionotes", "B. marginata", "B. coccinea", "B. speciosa" and "B. menziesii". Due to their size these species are popularly planted in parks, gardens and streets, the remaining species in this genus are only shrubs.Banksias are popular.

Banksia. garden plants in Australia because of their large, showy flower heads, and because the large amounts of nectar they produce attracts birds and small mammals. Popular garden species include "B. spinulosa", "B. ericifolia", "B. aemula" (Wallum Banksia ), "B. serrata" (Saw Banksia), "Banksia media" (Southern Plains Banksia) and the cultivar "Banksia" 'Giant Candles'. "Banksia" species are primarily propagated by seed in the home garden as cuttings can be difficult to strike. However commercial nurserymen extensively utilize the latter method (indeed, cultivars by nature must be vegetatively propagated by cuttings or grafting).Over time, dwarf cultivars and prostrate species are becoming more.

Banksia. popular as urban gardens grow ever smaller. These include miniature forms under 50 cm high of "B. spinulosa" and "B. media", as well as prostrate species such as "B. petiolaris" and "B. blechnifolia" .Banksias possibly require more maintenance than other Australian natives, though are fairly hardy if the right conditions are provided (sunny aspect and well drained sandy soil).They may need extra water during dry spells until established, which can take up to two years. If fertilised, only slow-release, low-phosphorus fertilizer should be used, as the proteoid roots may be damaged by high nutrient levels in the soil. All respond.

Banksia. well to some form of pruning.Within the Australian horticultural community there is an active subculture of "Banksia" enthusiasts who seek out interesting flower variants, breed and propagate cultivars, exchange materials and undertake research into cultivation problems and challenges. The main forum for exchange of information within this group is ASGAP's "Banksia Study Group".## Cut flower industry.With the exception of the nursery industry, "Banksia" have limited commercial use. Some species, principally "B. coccinea" (scarlet banksia), "B. baxteri", "B. hookeriana" (Hooker's banksia), "B. sceptrum" (sceptre banksia), and "B. prionotes" (acorn banksia), and less commonly "B. speciosa" (showy banksia), "B. menziesii" (Menzies' banksia),.

Banksia. "B. burdettii" and "B. ashbyi" are grown on farms in Western and Southern Australia, as well as Israel and Hawaii, and the flower heads harvested for the cut flower trade. Eastern species, such as "B. ericifolia", "B. robur" and "B. plagiocarpa", are sometimes cultivated for this purpose. The nectar is also sought by beekeepers, not for the quality of the dark-coloured honey, which is often poor, but because the trees provide an abundant and reliable source of nectar at times when other sources provide little.## Woodworking."Banksia" wood is reddish in color with an attractive grain but it is rarely used.

Banksia. as it warps badly on drying. It is occasionally used for ornamental purposes in wood turning and cabinet paneling. It has also been used to make keels for small boats. Historically, the wood of certain species such as "B. serrata" was used for yokes and boat parts. The large "cones" or seed pods of "B. grandis" are used for woodturning projects. They are also sliced up and sold as drink coasters; these are generally marketed as souvenirs for international tourists. Woodturners throughout the world value "Banksia" pods for making ornamental objects.## Indigenous uses.The Indigenous people of south-western Australia would suck.

Banksia. on the flower spikes to obtain the nectar, they also soaked the flower spikes in water to make a sweet drink. The Noongar people of southwest Western Australia also used infusions of the flower spikes to relieve coughs and sore throats. The Girai wurrung peoples of the western district of Victoria used the spent flower cones to strain water by placing the cones in their mouths and using them like a straw. "Banksia" trees are a reliable source of insect larvae which are extracted as food.## Cultural references.## Field guides and other technical resources.A number of field guides and other.

Banksia. semi-technical books on the genus have been published. These include:Field Guide to BanksiasWritten by Ivan Holliday and Geoffrey Watton and first published in 1975, this book contained descriptions and colour photographs of species known at the time. It was largely outdated by the publication of Alex George's classic 1981 monograph, but a revised and updated second edition was released in 1990."The Banksias"This three volume monograph contains watercolour paintings of every "Banksia" species by renowned botanical illustrator Celia Rosser, with accompanying text by Alex George. Its publication represents the first time that such a large genus has been entirely painted. Published.

It included every species known at the time, with a second edition appearing in 1987 and third in 1996.The "Banksia" AtlasIn 1983 the Australian Biological Resources Study (ABRS) decided to pilot an Australia-wide distribution study of a significant plant genus. "Banksia" was chosen because it was a high-profile, widely distributed.

Banksia. genus that was easily identified, but for which distribution and habitat was poorly known. The study mobilised over 400 volunteers, collecting over 25,000 field observations over a two-year period. Outcomes included the discovery of two new species, as well as new varieties and some rare colour variants, and discoveries of previously unknown populations of rare and threatened species. The collated data was used to create "The Banksia Atlas", which was first published in 1988.Banksias, Waratahs and Grevilleas and all other plants in the Australian Proteaceae familyWritten by J. W.

Ulmus americana. Ulmus americana, generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 °C (−44 °F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in.

Ulmus americana. Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701.For over 80 years, "U. americana" had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by the Agricultural Research Service of the USDA revealed that about 20% of wild American elms are diploid and may even constitute another species. Moreover, several triploid trees known only in.

Ulmus americana. cultivation, such as 'Jefferson', are possessed of a high degree of resistance to DED, which ravaged American elms in the 20th century. This suggests that the diploid parent trees, which have markedly smaller cells than the tetraploid, may too be highly resistant to the disease.## Classification."Ulmus americana" was first described and named by Carl Linnaeus in his "Species Plantarum", published in 1753. No subspecies or varieties are currently recognized within the species.## Description.The American elm is a deciduous hermaphroditic tree which, before the introduction of DED, commonly grew to more than 100 (ft) tall with a trunk whose diameter at.

Ulmus americana. breast height was more than 4 (ft), supporting a high, spreading umbrella-like canopy. The leaves are alternate, 7–20 cm long, with double-serrate margins and an oblique base. The perfect flowers are small, purple-brown and, being wind-pollinated, apetalous. The flowers are also protogynous, the female parts maturing before the male, thus reducing, but not eliminating, self-fertilization, and emerge in early spring before the leaves. The fruit is a flat samara 2 cm long by 1.5 cm broad, with a circular papery wing surrounding the single 4–5 mm seed. As in the closely related European White Elm "Ulmus laevis", the flowers and.

Ulmus americana. seeds are borne on 1–3 cm long stems. American Elm is wholly insensitive to daylight length (photoperiod), and will continue to grow well into autumn until injured by frost. Ploidy is "2n" = 56, or more rarely, "2n" = 28. ## Ecology.The American elm occurs naturally in an assortment of habitats, most notably rich bottomlands, floodplains, stream banks, and swampy ground, although it also often thrives on hillsides, uplands and other well-drained soils. On more elevated terrain, as in the Appalachian Mountains, it is most often found along rivers. The species' wind-dispersed seeds enable it to spread rapidly as suitable.

Ulmus americana. areas of habitat become available. American elm fruits in late spring (which can be as early as February and as late as June depending on the climate), the seeds usually germinating immediately, with no cold stratification needed (occasionally some might remain dormant until the following year). The species attains its greatest growth potential in the Northeastern US, while elms in the Deep South and Texas grow much smaller and have shorter lifespans, although conversely their survival rate in the latter regions is higher owing to the climate being less favorable to the spread of DED.In the United States, the American.

Ulmus americana. elm is a principal member of four major forest cover types: black ash-American elm-red maple; silver maple-American elm; sugarberry-American elm-green ash; and sycamore-sweetgum-American elm, with the first two of these types also occurring in Canada. A sugar maple-ironwood-American elm cover type occurs on some hilltops near Témiscaming, Quebec.The leaves of the American elm serve as food for the larvae of a number of species of Lepidoptera (see List of Lepidoptera that feed on elms). These include such butterflies as the Eastern Comma ("Polygonia comma"), Question Mark ("Polygonia interrogationis"), Mourning Cloak ("Nymphalis antiopa"), Painted Lady ("Vanessa cardui") and Red-spotted Purple ("Limenitis.

Ulmus americana. arthemis astyanax"), as well as such moths as the Columbian Silkmoth ("Hyalophora columbia") and the Banded Tussock Moth (Pale Tiger Moth) ("Halysidota tessellaris").## Pests and diseases.The American elm is highly susceptible to DED and elm yellows. In North America, there are three species of elm bark beetles: one native, "Hylurgopinus rufipes" ("native elm bark beetle"); and two invasive, "Scolytus multistriatus" ("smaller European elm bark beetle") and "Scolytus schevyrewi" ("banded elm bark beetle"). Although intensive feeding by elm bark beetles can kill weakened trees, their main impact is as vectors of DED.American elm is also moderately preferred for feeding and reproduction.

Ulmus americana. by the adult elm leaf beetle "Xanthogaleruca luteola" and highly preferred for feeding by the Japanese beetle "Popillia japonica" in the United States."U. americana" is also the most susceptible of all the elms to verticillium wilt, whose external symptoms closely mimic those of DED. However, the condition is far less serious, and afflicted trees should recover the following year.## Dutch elm disease.Dutch elm disease (DED) is a fungal disease that has ravaged the American elm, causing catastrophic die-offs in cities across the range. It has been estimated that only approximately 1 in 100,000 American elm trees is DED-tolerant, most known.

Ulmus americana. survivors simply having escaped exposure to the disease. However, in some areas still not infested by DED, the American elm continues to thrive, notably in Florida, Alberta and British Columbia. There is a notable grove of old American elm trees in Manhattan's Central Park. The trees there were apparently spared because of the grove's isolation in such an intensely urban setting.The American elm is particularly susceptible to disease because the period of infection often coincides with the period, approximately 30 days, of rapid terminal growth when new springwood vessels are fully functional. Spores introduced outside of this period remain largely.

Ulmus americana. static within the xylem and are thus relatively ineffective.The American elm's biology in some ways has helped to spare it from obliteration by DED, in contrast to what happened to the American chestnut with the chestnut blight. The elm's seeds are largely wind-dispersed, and the tree grows quickly and begins bearing seeds at a young age. It grows well along roads or railroad tracks, and in abandoned lots and other disturbed areas, where it is highly tolerant of most stress factors. Elms have been able to survive and to reproduce in areas where the disease had eliminated old trees, although.

Ulmus americana. most of these young elms eventually succumb to the disease at a relatively young age. There is some reason to hope that these elms will preserve the genetic diversity of the original population, and that they eventually will hybridize with DED-resistant varieties that have been developed or that occur naturally. After 20 years of research, American scientists first developed DED-resistant strains of elms in the late 1990s.Elms in forest and other natural areas have been less affected by DED than trees in urban environments due to lower environmental stress from pollution and soil compaction and due to occurring in smaller,.

Ulmus americana. more isolated populations.Fungicidal injections can be administered to valuable American elms, to prevent infection. Such injections generally are effective as a preventive measure for up to three years when performed before any symptoms have appeared, but may be ineffective once the disease is evident.## Cultivation.In the 19th and early 20th century, American elm was a common street and park tree owing to its tolerance of urban conditions, rapid growth, and graceful form. This however led to extreme overplanting of the species, especially to form living archways over streets, which ultimately produced an unhealthy monoculture of elms that had no resistance.

Ulmus americana. to disease and pests. Elms do not naturally form pure stands and trees used in landscaping were grown from a handful of cultivars, causing extremely low genetic diversity. These trees' rapid growth and longevity, leading to great size within decades, also favored its horticultural use before the advent of DED. Ohio botanist William B. Werthner, discussing the contrast between open-grown and forest-grown American elms, noted that:"In the open, with an abundance of air and light, the main trunk divides into several leading branches which leave the trunk at a sharp angle and continue to grow upward, gradually diverging, dividing and.

Ulmus americana. subdividing into long, flexible branchlets whose ends, at last, float lightly in the air, giving the tree a round, somewhat flattened top of beautifully regular proportions and characteristically fine twiggery."It is this distinctive growth form that is so valued in the open-grown American elms of street plantings, lawns, and parks; along most narrower streets, elms planted on opposite sides arch and blend together into a leafy canopy over the pavement. However, elms can assume many different sizes and forms depending on the location and climate zone. In 1926 the Klehm Nurseries of Arlington Heights, Illinois, wrote: "American Elms grown in.

Ulmus americana. the regular way from seedlings show extreme variability, growing up into trees of all shapes, some of them being very slow in growth while others are moderately rapid in development. The shapes run all the way from the true open excurrent growth to globular, or flat-topped, or pendant. As regards foliage, the leaves are from small to medium large, some shedding early and others late. This condition makes it difficult for the landscape architect to choose just the right trees to obtain the effect desired." The classic vase-shaped elm was mainly the result of selective breeding of a few cultivars.

Ulmus americana. and is much less likely to occur in the wild.## Gallery of American elm trees.American elms have been planted in North America beyond its natural range as far north as central Alberta. It also survives low desert heat at Phoenix, Arizona.Introductions across the Atlantic rarely prospered, even before the outbreak of DED. Introduced to the UK by James Gordon in 1752, the American elm was noted to be far more susceptible to insect foliage damage than native elms. The tree was propagated and marketed in the UK by the Hillier & Sons nursery, Winchester, Hampshire from 1945, with 450 sold.

Ulmus americana. in the period 1962 to 1977 when production ceased with the advent of the more virulent form of Dutch elm disease. Introduced to Australasia, the tree was listed by Australian nurseries in the early 20th century. It is known to have been planted along the Avenue of Honour at Ballarat, Victoria and the Avenue of Honour in Bacchus Marsh, Victoria. In addition, a heritage-listed planting of American elms can be found along Grant Crescent in Griffith, Australian Capital Territory. American Elms are only rarely found in New Zealand.## The American elm in literature.Mary Eleanor Wilkins Freeman, in her 1903 book.

Ulmus americana. of short stories, "Six Trees", wrote of the American elm: ## Cultivars.Numerous cultivars have been raised, originally for their aesthetic merit but more recently for their resistance to Dutch elm disease The total number of named cultivars is circa 45, at least 18 of which have probably been lost to cultivation as a consequence of DED or other factors: and others.The disease-resistant selections made available to commerce to date include 'Valley Forge', 'New Harmony', 'Princeton', 'Jefferson', 'Lewis & Clark', 'Miller Park', 'St. Croix', and a set of six different clones collectively known as 'American Liberty'. The United States National Arboretum.

Ulmus americana. released 'Valley Forge' and 'New Harmony' in late 1995, after screening tests performed in 1992–1993 showed both had unusually high levels of resistance to DED. 'Valley Forge' performed especially well in these tests.'Princeton' has been in occasional cultivation since the 1920s. 'Princeton' gained renewed attention after its performance in the 1992—1993 screening tests showed that it also had a high degree of disease resistance. A later test performed in 2002–2003 confirmed the disease resistance of 'Princeton', 'Valley Forge' and 'New Harmony', as well as that of 'Jefferson'. Thus far, plantings of these four varieties generally appear to be successful.In 2005,.

Ulmus americana. approximately 90 'Princeton' elms were planted along Pennsylvania Avenue in front of the White House in Washington, D.C. The trees, whose maintenance the National Park Service (NPS) manages, remain healthy and are thriving. However, it has been noted that "U. americana" cultivars are not recommended for more than singular plantings as they have unresolved DED and elm yellows concerns.It has also been noted that monoculture plantings of "U. americana" cultivars, such as those along Pennsylvania Avenue, have disproportionate vulnerabilities to disease. Further, long-term studies of 'Princeton' in Europe and the United States have suggested that the cultivar's resistance to DED.

Ulmus americana. may be limited (see Pests and diseases of 'Princeton').The National Elm Trial evaluated 19 elm cultivars commercially available in the United States in scientific plantings throughout the nation to assess and compare the strengths and weaknesses of each. The trial, which started in 2005, lasted for ten years. Based on the trial's final ratings, the preferred cultivars of "U. americana" are 'New Harmony' and 'Princeton'.'Jefferson' was released to wholesale nurseries in 2004 and is becoming increasingly available for planting. However, 'Jefferson' has not been widely tested beyond Washington, D.C. The National Elm Trial provided no data on ‘Jefferson’ because an.

Ulmus americana. error in tree identification had occurred earlier in the nursery trade. The error may still be causing nurseries to sell 'Princeton' elms that are mislabeled as 'Jefferson', although one can distinguish between the two cultivars as the trees mature.In 2007, the 'Elm Recovery Project' from the University of Guelph in Ontario, Canada, reported that cuttings from healthy surviving old elms surveyed across Ontario had been grown to produce a bank of resistant trees, isolated for selective breeding of highly resistant cultivars.In 1993, Mariam B. Sticklen and James L. Sherald reported the results of NPS-funded experiments conducted at Michigan State University.

Ulmus americana. in East Lansing that were designed to apply genetic engineering techniques to the development of DED-resistant strains of American elm trees. In 2007, AE Newhouse and F Schrodt of the State University of New York College of Environmental Science and Forestry in Syracuse reported that young transgenic American elm trees had shown reduced DED symptoms and normal mycorrhizal colonization. "Ulmus" 'Rebella' ("U. americana" × "U. parvifolia")## Hybrids and hybrid cultivars.Thousands of attempts to cross the American elm with the Siberian elm "U. pumila" failed. Attempts at the Arnold Arboretum using ten other American, European and Asiatic species also ended in.

Ulmus americana. failure, attributed to the differences in ploidy and operational dichogamy, although the ploidy factor has been discounted by other authorities.Success was eventually achieved with the autumn-flowering Chinese elm "Ulmus parvifolia" by the late Prof. Eugene Smalley towards the end of his career at the University of Wisconsin–Madison after he overcame the problem of keeping Chinese elm pollen alive until spring. Only one of the hybrid clones was commercially released, as 'Rebella' in 2011 by the German nursery Eisele GmbH; the clone is not available in the United States.Other artificial hybridizations with American elm are rare, and now regarded with suspicion.

Ulmus americana. Two such alleged successes by the nursery trade were 'Hamburg', and 'Kansas Hybrid', both with Siberian elm "Ulmus pumila". However, given the repeated failure with the two species by research institutions, it is now believed that the "American elm" in question was more likely to have been the red elm, "Ulmus rubra".## Other uses.## Wood.The American elm's wood is coarse, hard, and tough, with interlacing, contorted fibers that make it difficult to split or chop, and cause it to warp after sawing. Accordingly, the wood originally had few uses, save for making hubs for wagon wheels. Later, with the advent.

Ulmus americana. of mechanical sawing, American elm wood was used for barrel staves, trunk-slats, and hoop-poles, and subsequently became fundamental to the manufacture of wooden automobile bodies, with the intricate fibers holding screws unusually well.## Pioneer and traditional uses.Young twigs and branchlets of the American elm have tough, fibrous bark that has been used as a tying and binding material, even for rope swings for children, and also for making whips.## Notable trees.A number of mostly small to medium-sized American elms now survive in woodlands, suburban areas, and occasionally cities, where the survivors have often been relatively isolated from other elms and.

Ulmus americana. thus spared a severe exposure to the fungus. For example, in Central Park and Tompkins Square Park in New York City, stands of several large elms originally planted by Frederick Law Olmsted survive because of their isolation from neighboring areas in New York where there had been heavy mortality. The Olmsted-designed park system in Buffalo, NY did not fare as well.A row of mature American elms lines Central Park along the entire length of Fifth Avenue from 59th to 110th Streets. In Akron, Ohio there is a very old elm tree that has not been infected. In historical areas of.

Ulmus americana. Philadelphia, Pennsylvania, there are also a few mature American elms still standing — notably in Independence Square and the Quadrangle at the University of Pennsylvania, and also at the nearby campuses of Haverford College, Swarthmore College, and Pennsylvania State University, believed to be the largest remaining stand in the country.There are several large American Elm trees in western Massachusetts. A large specimen, which stands on Summer Street in the Berkshire County town of Lanesborough, Massachusetts, has been kept alive by antifungal treatments. Rutgers University has preserved 55 mature elms on and in the vicinity of Voorhees Mall on the College.

Ulmus americana. Avenue Campus in New Brunswick, New Jersey in addition to seven disease-resistant trees that have been planted in this area of the campus in recent years.The largest surviving urban forest of American elms in North America is believed to be in the city of Winnipeg, Manitoba, Canada, where close to 200,000 elms remain. The city of Winnipeg spends $3M annually to aggressively combat the disease utilizing Dursban Turf and the Dutch Trig vaccine, losing 1500–4000 trees per year.Governmental agencies, educational institutions or other organizations in most of the states that are within the United States maintain lists of champion or.

Ulmus americana. big trees that describe the locations and characteristics of those states' largest American elm trees (see List of state champion American elm trees). The current United States national champion American elm tree is located in Iberville Parish, Louisiana. When measured in 2010, the tree had a trunk circumference of 324 (in), a height of 111 (ft) and an average crown spread of 79 (ft).The current Tree Register of the British Isles (TROBI) champion grows in Avondale Forest near Rathdrum, County Wicklow, Ireland. The tree had a height of 22.5 (m) and a diameter at breast height of 98 (cm) (circumference.

Ulmus americana. of 308 (cm)) when measured in 2000. The tree replaced on the Register a larger champion located in Woodvale Cemetery in Sussex, England, which in 1988 had a height of 27 (m) and a diameter of 115 (cm) (circumference of 361 (cm)).Other large or otherwise significant American elm trees have included:## Treaty Elm.The Treaty Elm, Philadelphia, Pennsylvania. In what is now Penn Treaty Park, the founder of Pennsylvania, William Penn, is said to have entered into a treaty of peace in 1683 with the native Lenape Turtle Clan under a picturesque elm tree immortalized in a painting by Benjamin West.

Ulmus americana. West made the tree, already a local landmark, famous by incorporating it into his painting after hearing legends (of unknown veracity) about the tree being the location of the treaty. No documentary evidence exists of any treaty Penn signed beneath a particular tree. On March 6, 1810 a great storm blew the tree down. Measurements taken at the time showed it to have a circumference of 24 (ft), and its age was estimated to be 280 years. Wood from the tree was made into furniture, canes, walking sticks and various trinkets that Philadelphians kept as relics.## Washington Elm (Massachusetts).The Washington.

Ulmus americana. Elm, Cambridge, Massachusetts. George Washington is said to have taken command of the American Continental Army under the Washington Elm in Cambridge on July 3, 1775. The tree survived until the 1920s and "was thought to be a survivor of the primeval forest". In 1872, a large branch fell from it and was used to construct a pulpit for a nearby church. The tree, an American white elm, became a celebrated attraction, with its own plaque, a fence constructed around it and a road moved in order to help preserve it. The tree was cut down (or fell—sources differ) in.

Ulmus americana. October 1920 after an expert determined it was dead.The city of Cambridge had plans for it to be "carefully cut up and a piece sent to each state of the country and to the District of Columbia and Alaska," according to "The Harvard Crimson". As late as the early 1930s, garden shops advertised that they had cuttings of the tree for sale, although the accuracy of the claims has been doubted. A Harvard "professor of plant anatomy" examined the tree rings days after the tree was felled and pronounced it between 204 and 210 years old, making it at most.

Ulmus americana. 62 years old when Washington took command of the troops at Cambridge. The tree would have been a little more than two feet in diameter (at 30 inches above ground) in 1773.In 1896, an alumnus of the University of Washington, obtained a rooted cutting of the Cambridge tree and sent it to Professor Edmund Meany at the university. The cutting was planted, cuttings were then taken from it, including one planted on February 18, 1932, the 200th anniversary of the birth of George Washington, for whom Washington state is named. That tree remains on the campus of the Washington State.

Ulmus americana. Capitol. Just to the west of the tree is a small elm from a cutting made in 1979.## Washington Elm (District of Columbia).George Washington's Elm, Washington, D.C. George Washington supposedly had a favorite spot under an elm tree near the United States Capitol Building from which he would watch construction of the building. The elm stood near the Senate wing of the Capitol building until 1948.## Logan Elm.The Logan Elm that stood near Circleville, Ohio, was one of the largest American elms in the world. The 65 (ft) tree had a trunk circumference of 24 (ft) and a crown spread.

Ulmus americana. of 180 (ft). Weakened by DED, the tree died in 1964 from storm damage. The Logan Elm State Memorial commemorates the site and preserves various associated markers and monuments. According to tradition, Chief Logan of the Mingo tribe delivered a passionate speech at a peace-treaty meeting under this elm in 1774.## "Herbie".Another notable American elm, named Herbie, was the tallest American elm in New England until it was cut down on January 19, 2010, after it succumbed to DED. Herbie was 110 (ft) tall at its peak and had a circumference of 20.3 (ft), or a diameter of approximately 6.5.

Ulmus americana. (ft). The tree stood in Yarmouth, Maine, where it was cared for by the town's tree warden, Frank Knight.When cut down, Herbie was 217 years old. Herbie's wood is of interest to dendroclimatologists, who will use cross-sections of the trunk to help answer questions about climate during the tree's lifetime.## The Glencorradale Elm.The Glencorradale Elm on Prince Edward Island, Canada, is a surviving wild elm believed to be several hundred years old.## Survivor Tree.An American elm located in a parking lot directly across the street from the Alfred P. Murrah Federal Building in Oklahoma City survived the Oklahoma City bombing.

Ulmus americana. on April 19, 1995 that killed 168 people and destroyed the Murrah building. Damaged in the blast, with fragments lodged in its trunk and branches, it was nearly cut down in efforts to recover evidence. However, nearly a year later the tree began to bloom. Then known as the Survivor Tree, it became an important part of the Oklahoma City National Memorial, and is featured prominently on the official logo of the memorial.## Parliament Hill Elm.The Parliament Hill Elm was planted in Ottawa, Canada, in the late 1910s or early 1920s when Centre Block was rebuilt following the Great fire.

Ulmus americana. of 1916. The tree grew for approximately a century next to a statue of John A. Macdonald and was one of the few in the region to survive the spread of DED in the 1970s and 1980s. Despite protests from Ottawa area environmentalists and resistance from Opposition Members of Parliament the tree was removed in April 2019 to make way for new Centre Block renovations.## Landscaped parks.## Central Park.New York City's Central Park is home to approximately 1,200 American elms. The oldest of these elms were planted during the 1860s by Frederick Law Olmsted, making them among the oldest stands.

Ulmus americana. of American elms in the world. The trees are particularly noteworthy along the Mall and Literary Walk, where four lines of American elms stretch over the walkway forming a cathedral-like covering. A part of New York City's urban ecology, the elms improve air and water quality, reduce erosion and flooding, and decrease air temperatures during warm days.While the stand is still vulnerable to DED, in the 1980s the Central Park Conservancy undertook aggressive countermeasures such as heavy pruning and removal of extensively diseased trees. These efforts have largely been successful in saving the majority of the trees, although several are.

Ulmus americana. still lost each year. Younger American elms that have been planted in Central Park since the outbreak are of the DED-resistant 'Princeton' and 'Valley Forge' cultivars.## National Mall.Several rows of American elm trees that the National Park Service first planted during the 1930s line much of the 1.9 miles (3.0 km) length of the National Mall in Washington, D.C. DED first appeared on the trees during the 1950s and reached a peak in the 1970s. The NPS used a number of methods to control the epidemic, including sanitation, pruning, injecting trees with fungicide and replanting with DED-resistant cultivars. The NPS.

Ulmus americana. combated the disease's local insect vector, the smaller European elm bark beetle ("Scolytus multistriatus"), by trapping and by spraying with insecticides. As a result, the population of American elms planted on the Mall and its surrounding areas has remained intact for more than 80 years.## In art and photography.The nobility and arching grace of the American Elm in its heyday, on farms, in villages, in towns and on campuses, were celebrated in the books of photographs of Wallace Nutting ("Massachusetts Beautiful", N.Y. 1923, and other volumes in the series) and of Samuel Chamberlain ("The New England Image", New York, 1962).

Octagon. squares themselves form the vertices of a square.## Regular octagon.A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol {8}.The internal angle at each vertex of a regular octagon is 135° (formula_1 radians). The central angle is 45° (formula_2 radians).## Area.The area of a regular octagon of side length "a" is given byformula_3In terms of the circumradius "R", the area isformula_4In terms of the apothem "r" (see also.
