Hexagon. In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.## Regular hexagon.A "regular hexagon" has Schläfli symbol {6} and can also be constructed as a truncated equilateral triangle, t{3}, which alternates two types of edges.A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle).The common length of the sides equals the radius.

Hexagon. of the circumscribed circle or circumcircle, which equals formula_1 times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has six rotational symmetries ("rotational symmetry of order six") and six reflection symmetries ("six lines of symmetry"), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side. From this it can be seen that a triangle with a vertex at the center of the regular hexagon and sharing one side with the hexagon is equilateral, and that the regular hexagon.

Hexagon. can be partitioned into six equilateral triangles.Like squares and equilateral triangles, regular hexagons fit together without any gaps to "tile the plane" (three hexagons meeting at every vertex), and so are useful for constructing tessellations. The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials. The Voronoi diagram of a regular triangular lattice is the honeycomb tessellation of hexagons. It is not usually considered a triambus, although it is equilateral.## Parameters.The maximal diameter (which corresponds to the long diagonal of the hexagon), "D", is twice the maximal.

Hexagon. radius or circumradius, "R", which equals the side length, "t". The minimal diameter or the diameter of the inscribed circle (separation of parallel sides, flat-to-flat distance, short diagonal or height when resting on a flat base), "d", is twice the minimal radius or inradius, "r". The maxima and minima are related by the same factor:formula_2 and, similarly, formula_3The area of a regular hexagonformula_4For any regular polygon, the area can also be expressed in terms of the apothem "a" and the perimeter "p". For the regular hexagon these are given by "a" = "r", and "p"formula_5, soformula_6The regular hexagon fills the.

Hexagon. fraction formula_7 of its circumscribed circle.If a regular hexagon has successive vertices A, B, C, D, E, F and if P is any point on the circumcircle between B and C, then .It follows from the ratio of circumradius to inradius that the height-to-width ratio of a regular hexagon is 1:1.1547005; that is, a hexagon with a long diagonal of 1.0000000 will have a distance of 0.8660254 between parallel sides.## Point in plane.For an arbitrary point in the plane of a regular hexagon with circumradius formula_8, whose distances to the centroid of the regular hexagon and its six vertices are.

Hexagon. formula_9 and formula_10 respectively, we haveformula_11formula_12formula_13If formula_10 are the distances from the vertices of a regular hexagon to any point on its circumcircle, then formula_15## Symmetry.The "regular hexagon" has D6 symmetry. There are 16 subgroups. There are 8 up to isomorphism: itself (D6), 2 dihedral: (D3, D2), 4 cyclic: (Z6, Z3, Z2, Z1) and the trivial (e)These symmetries express nine distinct symmetries of a regular hexagon. John Conway labels these by a letter and group order. r12 is full symmetry, and a1 is no symmetry. p6, an isogonal hexagon constructed by three mirrors can alternate long and short edges, and.

Hexagon. d6, an isotoxal hexagon constructed with equal edge lengths, but vertices alternating two different internal angles. These two forms are duals of each other and have half the symmetry order of the regular hexagon. The i4 forms are regular hexagons flattened or stretched along one symmetry direction. It can be seen as an elongated rhombus, while d2 and p2 can be seen as horizontally and vertically elongated kites. g2 hexagons, with opposite sides parallel are also called hexagonal parallelogons.Each subgroup symmetry allows one or more degrees of freedom for irregular forms. Only the g6 subgroup has no degrees of freedom.

Hexagon. but can seen as directed edges.Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations.## A2 and G2 groups.The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them.The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between them.## Dissection.Coxeter states that.

Hexagon. every zonogon (a 2"m"-gon whose opposite sides are parallel and of equal length) can be dissected into parallelograms. In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. This decomposition of a regular hexagon is based on a Petrie polygon projection of a cube, with 3 of 6 square faces. Other parallelogons and projective directions of the cube are dissected within rectangular cuboids.## Related polygons and tilings.A regular hexagon has Schläfli symbol {6}. A regular hexagon is a part of the regular hexagonal tiling, {6,3}, with three hexagonal faces around.

Hexagon. each vertex.A regular hexagon can also be created as a truncated equilateral triangle, with Schläfli symbol t{3}. Seen with two types (colors) of edges, this form only has D3 symmetry.A truncated hexagon, t{6}, is a dodecagon, {12}, alternating two types (colors) of edges. An alternated hexagon, h{6}, is an equilateral triangle, {3}. A regular hexagon can be stellated with equilateral triangles on its edges, creating a hexagram. A regular hexagon can be dissected into six equilateral triangles by adding a center point. This pattern repeats within the regular triangular tiling.A regular hexagon can be extended into a regular dodecagon by.

Hexagon. adding alternating squares and equilateral triangles around it. This pattern repeats within the rhombitrihexagonal tiling.## Self-crossing hexagons.There are six self-crossing hexagons with the vertex arrangement of the regular hexagon:## Hexagonal structures.From bees' honeycombs to the Giant's Causeway, hexagonal patterns are prevalent in nature due to their efficiency. In a hexagonal grid each line is as short as it can possibly be if a large area is to be filled with the fewest hexagons. This means that honeycombs require less wax to construct and gain much strength under compression.Irregular hexagons with parallel opposite edges are called parallelogons and can also tile.

Hexagon. the plane by translation. In three dimensions, hexagonal prisms with parallel opposite faces are called parallelohedrons and these can tessellate 3-space by translation.## Tesselations by hexagons.In addition to the regular hexagon, which determines a unique tessellation of the plane, any irregular hexagon which satisfies the Conway criterion will tile the plane.## Hexagon inscribed in a conic section.Pascal's theorem (also known as the "Hexagrammum Mysticum Theorem") states that if an arbitrary hexagon is inscribed in any conic section, and pairs of opposite sides are extended until they meet, the three intersection points will lie on a straight line, the "Pascal line.

Hexagon. of that configuration.## Cyclic hexagon.The Lemoine hexagon is a cyclic hexagon (one inscribed in a circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point.If the successive sides of a cyclic hexagon are "a", "b", "c", "d", "e", "f", then the three main diagonals intersect in a single point if and only if .If, for each side of a cyclic hexagon, the adjacent sides are extended to their intersection, forming a triangle exterior to the given side, then the segments.

Hexagon. connecting the circumcenters of opposite triangles are concurrent.If a hexagon has vertices on the circumcircle of an acute triangle at the six points (including three triangle vertices) where the extended altitudes of the triangle meet the circumcircle, then the area of the hexagon is twice the area of the triangle.## Hexagon tangential to a conic section.Let ABCDEF be a hexagon formed by six tangent lines of a conic section. Then Brianchon's theorem states that the three main diagonals AD, BE, and CF intersect at a single point.In a hexagon that is tangential to a circle and that has consecutive sides.

The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes.A regular skew hexagon is vertex-transitive with equal edge lengths. In three dimensions it will be.

Hexagon. a zig-zag skew hexagon and can be seen in the vertices and side edges of a triangular antiprism with the same D3d, [2+,6] symmetry, order 12.The cube and octahedron (same as triangular antiprism) have regular skew hexagons as petrie polygons.## Petrie polygons.The regular skew hexagon is the Petrie polygon for these higher dimensional regular, uniform and dual polyhedra and polytopes, shown in these skew orthogonal projections:## Convex equilateral hexagon.A "principal diagonal" of a hexagon is a diagonal which divides the hexagon into quadrilaterals.

Sea otter. The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 (kg), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.The sea otter inhabits nearshore environments, where it dives to the sea floor to.

Sea otter. were once estimated at 150,000–300,000, were hunted extensively for their fur between 1741 and 1911, and the world population fell to 1,000–2,000 individuals living in a fraction of their historic range. A subsequent international ban on hunting, sea otter conservation efforts, and reintroduction programs into previously populated areas have contributed to numbers rebounding, and the species occupies about two-thirds of its former range. The recovery of the sea otter is considered an important success in marine conservation, although populations in the Aleutian Islands and California have recently declined or have plateaued at depressed levels. For these reasons, the sea otter.

Sea otter. remains classified as an endangered species.## Evolution.The sea otter is the heaviest (the giant otter is longer, but significantly slimmer) member of the family Mustelidae, a diverse group that includes the 13 otter species and terrestrial animals such as weasels, badgers, and minks. It is unique among the mustelids in not making or burrows, in having no functional anal scent glands, and in being able to live its entire life without leaving the water. The only living member of the genus "Enhydra", the sea otter is so different from other mustelid species that, as recently as 1982, some scientists believed.

Sea otter. spread east to the Aleutian Islands, mainland Alaska, and down the North American coast. In comparison to cetaceans, sirenians, and pinnipeds, which entered the water approximately 50, 40, and 20 million years ago, respectively, the sea otter is a relative newcomer to a marine existence. In some respects, though, the sea otter is more fully adapted to water than pinnipeds, which must haul out on land or ice to give birth. The full genome of the northern sea otter ("Enhydra lutris kenyoni") was sequenced in 2017 and may allow for examination of the sea otter's evolutionary divergence from terrestrial mustelids.##.

Sea otter. Taxonomy.The first scientific description of the sea otter is contained in the field notes of Georg Steller from 1751, and the species was described by Carl Linnaeus in his landmark 1758 10th edition of "Systema Naturae". Originally named "Lutra marina", it underwent numerous name changes before being accepted as "Enhydra lutris" in 1922. The generic name "Enhydra", derives from the Ancient Greek "en"/εν "in" and "hydra"/ύδρα "water", meaning "in the water", and the Latin word "lutris", meaning "otter". It was formerly sometimes referred to as the "sea beaver".## Subspecies.Three subspecies of the sea otter are recognized with distinct geographical distributions.

Sea otter. Description.The sea otter is one of the smallest marine mammal species, but it is the heaviest mustelid. Male sea otters usually weigh 22 to 45 (kg) and are 1.2 to 1.5 (m) in length, though specimens up to 54 (kg) have been recorded. Females are smaller, weighing 14 to 33 (kg) and measuring 1.0 to 1.4 (m) in length. For its size, the male otter's baculum is very large, massive and bent upwards, measuring 150 (mm) in length and 15 (mm) at the base.Unlike most other marine mammals, the sea otter has no blubber and relies on its exceptionally thick.

Sea otter. fur to keep warm. With up to 150000 (/cm2), its fur is the densest of any animal. The fur consists of long, waterproof guard hairs and short underfur; the guard hairs keep the dense underfur layer dry. There is an air compartment between the thick fur and the skin where air is trapped and heated by the body. Cold water is kept completely away from the skin and heat loss is limited. However, this air compartment can be disadvantageous because as the sea otter dives deeper into the water column, the air compartment compresses and heat needed to warm the.

Sea otter. the urchin's shell.The sea otter's use of rocks when hunting and feeding makes it one of the few mammal species to use tools. To open hard shells, it may pound its prey with both paws against a rock on its chest. To pry an abalone off its rock, it hammers the abalone shell using a large stone, with observed rates of 45 blows in 15 seconds. Releasing an abalone, which can cling to rock with a force equal to 4,000 times its own body weight, requires multiple dives.## Social structure.Although each adult and independent juvenile forages alone, sea otters tend.

Sea otter. to rest together in single-sex groups called "rafts". A raft typically contains 10 to 100 animals, with male rafts being larger than female ones. The largest raft ever seen contained over 2000 sea otters. To keep from drifting out to sea when resting and eating, sea otters may wrap themselves in kelp.A male sea otter is most likely to mate if he maintains a breeding territory in an area that is also favored by females. As autumn is the peak breeding season in most areas, males typically defend their territory only from spring to autumn. During this time, males patrol.

Sea otter. jaws during copulation. Visible scars are often present on females from this behavior.Births occur year-round, with peaks between May and June in northern populations and between January and March in southern populations. Gestation appears to vary from four to twelve months, as the species is capable of delayed implantation followed by four months of pregnancy. In California, sea otters usually breed every year, about twice as often as those in Alaska.Birth usually takes place in the water and typically produces a single pup weighing 1.4 to 2.3 (kg). Twins occur in 2% of births; however, usually only one pup survives.

Sea otter. At birth, the eyes are open, ten teeth are visible, and the pup has a thick coat of baby fur. Mothers have been observed to lick and fluff a newborn for hours; after grooming, the pup's fur retains so much air, the pup floats like a cork and cannot dive. The fluffy baby fur is replaced by adult fur after about 13 weeks.Nursing lasts six to eight months in Californian populations and four to twelve months in Alaska, with the mother beginning to offer bits of prey at one to two months. The milk from a sea otter's two abdominal.

Sea otter. water, sometimes wrapped in kelp to keep it from floating away; if the pup is not sleeping, it cries loudly until she returns. Mothers have been known to carry their pups for days after the pups' deaths.Females become sexually mature at around three or four years of age and males at around five; however, males often do not successfully breed until a few years later. A captive male sired offspring at age 19. In the wild, sea otters live to a maximum age of 23 years, with lifespans ranging from 10 to 15 years for males and 15–20 years for.

Sea otter. females. Several captive individuals have lived past 20 years, and a female at the Seattle Aquarium died at the age of 28 years. Sea otters in the wild often develop worn teeth, which may account for their apparently shorter lifespans.## Population and distribution.Sea otters live in coastal waters 15 to 23 (m) deep, and usually stay within a kilometre ( mi) of the shore. They are found most often in areas with protection from the most severe ocean winds, such as rocky coastlines, thick kelp forests, and barrier reefs. Although they are most strongly associated with rocky substrates, sea otters.

Sea otter. can also live in areas where the sea floor consists primarily of mud, sand, or silt. Their northern range is limited by ice, as sea otters can survive amidst drift ice but not land-fast ice. Individuals generally occupy a home range a few kilometres long, and remain there year-round.The sea otter population is thought to have once been 150,000 to 300,000, stretching in an arc across the North Pacific from northern Japan to the central Baja California Peninsula in Mexico. The fur trade that began in the 1740s reduced the sea otter's numbers to an estimated 1,000 to 2,000 members.

Sea otter. in 13 colonies. Hunting records researched by historian Adele Ogden place the westernmost limit of the hunting grounds off the northern Japanese island of Hokkaido and the easternmost limit off Punta Morro Hermosa about 21+1/2 (mi) south of Punta Eugenia, Baja California's westernmost headland in Mexico.In about two-thirds of its former range, the species is at varying levels of recovery, with high population densities in some areas and threatened populations in others. Sea otters currently have stable populations in parts of the Russian east coast, Alaska, British Columbia, Washington, and California, with reports of recolonizations in Mexico and Japan. Population.

Sea otter. estimates made between 2004 and 2007 give a worldwide total of approximately 107,000 sea otters.## Japan.Adele Ogden wrote in "The California Sea Otter Trade" that sea otter were hunted "from Yezo northeastward past the Kuril Group and Kamchatka to the Aleutian Chain". "Yezo" refers to the island of Hokkaido in northern Japan; the only confirmed sea otter population in Japanese territory is on the coast surrounding the town of Erimo, Hokkaido.## Russia.Currently, the most stable and secure part of the sea otter's range is Russia. Before the 19th century, around 20,000 to 25,000 sea otters lived near the Kuril Islands,.

Sea otter. with more near Kamchatka and the Commander Islands. After the years of the Great Hunt, the population in these areas, currently part of Russia, was only 750. By 2004, sea otters had repopulated all of their former habitat in these areas, with an estimated total population of about 27,000. Of these, about 19,000 are at the Kurils, 2,000 to 3,500 at Kamchatka and another 5,000 to 5,500 at the Commander Islands. Growth has slowed slightly, suggesting the numbers are reaching carrying capacity.## British Columbia.Along the North American coast south of Alaska, the sea otter's range is discontinuous. A remnant population.

Sea otter. survived off Vancouver Island into the 20th century, but it died out despite the 1911 international protection treaty, with the last sea otter taken near Kyuquot in 1929. From 1969 to 1972, 89 sea otters were flown or shipped from Alaska to the west coast of Vancouver Island. This population increased to over 5,600 in 2013 with an estimated annual growth rate of 7.2%, and their range on the island's west coast extended north to Cape Scott and across the Queen Charlotte Strait to the Broughton Archipelago and south to Clayoquot Sound and Tofino. In 1989, a separate colony was.

Sea otter. discovered in the central British Columbia coast. It is not known if this colony, which numbered about 300 animals in 2004, was founded by transplanted otters or was a remnant population that had gone undetected. By 2013, this population exceeded 1,100 individuals, was increasing at an estimated 12.6% annual rate, and its range included Aristazabal Island, and Milbanke Sound south to Calvert Island. In 2008, Canada determined the status of sea otters to be "special concern".## United States.## Alaska.Alaska is the central area of the sea otter's range. In 1973, the population in Alaska was estimated at between 100,000 and.

Sea otter. 125,000 animals. By 2006, though, the Alaska population had fallen to an estimated 73,000 animals. A massive decline in sea otter populations in the Aleutian Islands accounts for most of the change; the cause of this decline is not known, although orca predation is suspected. The sea otter population in Prince William Sound was also hit hard by the Exxon Valdez oil spill, which killed thousands of sea otters in 1989.## Washington.In 1969 and 1970, 59 sea otters were translocated from Amchitka Island to Washington, and released near La Push and Point Grenville. The translocated population is estimated to have.

Sea otter. declined to between 10 and 43 individuals before increasing, reaching 208 individuals in 1989. As of 2017, the population was estimated at over 2,000 individuals, and their range extends from Point Grenville in the south to Cape Flattery in the north and east to Pillar Point along the Strait of Juan de Fuca.In Washington, sea otters are found almost exclusively on the outer coasts. They can swim as close as six feet off shore along the Olympic coast. Reported sightings of sea otters in the San Juan Islands and Puget Sound almost always turn out to be North American river.

Sea otter. otters, which are commonly seen along the seashore. However, biologists have confirmed isolated sightings of sea otters in these areas since the mid-1990s.## Oregon.The last native sea otter in Oregon was probably shot and killed in 1906. In 1970 and 1971, a total of 95 sea otters were transplanted from Amchitka Island, Alaska to the Southern Oregon coast. However, this translocation effort failed and otters soon again disappeared from the state. In 2004, a male sea otter took up residence at Simpson Reef off of Cape Arago for six months. This male is thought to have originated from a colony.

Sea otter. in Washington, but disappeared after a coastal storm. On 18 February 2009, a male sea otter was spotted in Depoe Bay off the Oregon Coast. It could have traveled to the state from either California or Washington.## California.The historic population of California sea otters was estimated at 16,000 before the fur trade decimated the population, leading to their assumed extinction. Today's population of California sea otters are the descendants of a single colony of about 50 sea otters located near Bixby Creek Bridge in March 1938 by Howard G. Sharpe, owner of the nearby Rainbow Lodge on Bixby Bridge in.

Sea otter. Big Sur. Their principal range has gradually expanded and extends from Pigeon Point in San Mateo County to Santa Barbara County.Sea otters were once numerous in San Francisco Bay. Historical records revealed the Russian-American Company sneaked Aleuts into San Francisco Bay multiple times, despite the Spanish capturing or shooting them while hunting sea otters in the estuaries of San Jose, San Mateo, San Bruno and around Angel Island. The founder of Fort Ross, Ivan Kuskov, finding otters scarce on his second voyage to Bodega Bay in 1812, sent a party of Aleuts to San Francisco Bay, where they met another.

Sea otter. Russian party and an American party, and caught 1,160 sea otters in three months. By 1817, sea otters in the area were practically eliminated and the Russians sought permission from the Spanish and the Mexican governments to hunt further and further south of San Francisco. Remnant sea otter populations may have survived in the bay until 1840, when the Rancho Punta de Quentin was granted to Captain John B. R. Cooper, a sea captain from Boston, by Mexican Governor Juan Bautista Alvarado along with a license to hunt sea otters, reportedly then prevalent at the mouth of Corte Madera Creek.In.

Sea otter. the late 1980s, the USFWS relocated about 140 southern sea otters to San Nicolas Island in southern California, in the hope of establishing a reserve population should the mainland be struck by an oil spill. To the surprise of biologists, the majority of the San Nicolas sea otters swam back to the mainland. Another group of twenty swam 74 (mi) north to San Miguel Island, where they were captured and removed. By 2005, only 30 sea otters remained at San Nicolas, although they were slowly increasing as they thrived on the abundant prey around the island. The plan that authorized.

Sea otter. the translocation program had predicted the carrying capacity would be reached within five to 10 years. The spring 2016 count at San Nicolas Island was 104 sea otters, continuing a 5-year positive trend of over 12% per year. Sea otters were observed twice in Southern California in 2011, once near Laguna Beach and once at Zuniga Point Jetty, near San Diego. These are the first documented sightings of otters this far south in 30 years.When the USFWS implemented the translocation program, it also attempted, in 1986, to implement "zonal management" of the Californian population. To manage the competition between sea.

Sea otter. response to lawsuits filed by the Santa Barbara-based Environmental Defense Center and the Otter Project, on 19 December 2012 the USFWS declared that the "no otter zone" experiment was a failure, and will protect the otters re-colonizing the coast south of Point Conception as threatened species. Although abalone fisherman blamed the incursions of sea otters for the decline of abalone, commercial abalone fishing in southern California came to an end from overfishing in 1997, years before significant otter moved south of Point Conception. In addition, white abalone ("Haliotis sorenseni"), a species never overlapping with sea otter, had declined in numbers.

Sea otter. 99% by 1996, and became the first marine invertebrate to be federally listed as endangered.Although the southern sea otter's range has continuously expanded from the remnant population of about 50 individuals in Big Sur since protection in 1911, from 2007 to 2010, the otter population and its range contracted and since 2010 has made little progress. As of spring 2010, the northern boundary had moved from about Tunitas Creek to a point 2 (km) southeast of Pigeon Point, and the southern boundary has moved along the Gaviota Coast from approximately Coal Oil Point to Gaviota State Park. A toxin called.

Sea otter. microcystin, produced by a type of cyanobacteria ("Microcystis"), seems to be concentrated in the shellfish the otters eat, poisoning them. Cyanobacteria are found in stagnant water enriched with nitrogen and phosphorus from septic tank and agricultural fertilizer runoff, and may be flushed into the ocean when streamflows are high in the rainy season. A record number of sea otter carcasses were found on California's coastline in 2010, with increased shark attacks an increasing component of the mortality. Great white sharks do not consume relatively fat-poor sea otters but shark-bitten carcasses have increased from 8% in the 1980s to 15% in.

Sea otter. the 1990s and to 30% in 2010 and 2011.For southern sea otters to be considered for removal from threatened species listing, the U.S. Fish and Wildlife Service (USFWS) determined that the population should exceed 3,090 for three consecutive years. In response to recovery efforts, the population climbed steadily from the mid-20th century through the early 2000s, then remained relatively flat from 2005 to 2014 at just under 3,000. There was some contraction from the northern (now Pigeon Point) and southern limits of the sea otter's range during the end of this period, circumstantially related to an increase in lethal shark.

Sea otter. bites, raising concerns that the population had reached a plateau. However, the population increased markedly from 2015 to 2016, with the United States Geological Survey (USGS) California sea otter survey 3-year average reaching 3,272 in 2016, the first time it exceeded the threshold for delisting from the Endangered Species Act (ESA). If populations continued to grow and ESA delisting occurred, southern sea otters would still be fully protected by state regulations and the Marine Mammal Protection Act, which set higher thresholds for protection, at approximately 8,400 individuals. However, ESA delisting seems unlikely due to a precipitous population decline recorded in.

Sea otter. the spring 2017 USGS sea otter survey count, from the 2016 high of 3,615 individuals to 2,688, a loss of 25% of the California sea otter population.## Mexico.Historian Adele Ogden described sea otters are particularly abundant in "Lower California", now the Baja California Peninsula, where "seven bays...were main centers". The southernmost limit was Punta Morro Hermoso about 21+1/2 (mi) south of Punta Eugenia, in turn a headland at the southwestern end of Sebastián Vizcaíno Bay, on the west coast of the Baja Peninsula. Otter were also taken from San Benito Island, Cedros Island, and Isla Natividad in the Bay. By.

Sea otter. the early 1900s, Baja's sea otters were extirpated by hunting. In a 1997 survey, small numbers of sea otters, including pups, were reported by local fishermen, but scientists could not confirm these accounts. However, male and female otters have been confirmed by scientists off shores of the Baja Peninsula in a 2014 study, who hypothesize that otter dispersed there beginning in 2005. These sea otters may have dispersed from San Nicolas Island, which is 300 (km) away, as individuals have been recorded traversing distances of over 800 (km). Genetic analysis of most of these animals were consistent with California, i.e.

Sea otter. United States, otter origins, however one otter had a haplotype not previously reported, and could represent a remnant of the original native Mexican otter population.## Ecology.## Diet.High energetic requirements of sea otter metabolism require them to consume at least 20% of their body weight a day. Surface swimming and foraging are major factors in their high energy expenditure due to drag on the surface of the water when swimming and the thermal heat loss from the body during deep dives when foraging. Sea otter muscles are specially adapted to generate heat without physical activity.Sea otters consume over 100 prey species.

Sea otter. also eaten. In studies performed at Amchitka Island in the 1960s, where the sea otter population was at carrying capacity, 50% of food found in sea otter stomachs was fish. The fish species were usually bottom-dwelling and sedentary or sluggish forms, such as "Hemilepidotus hemilepidotus" and family Tetraodontidae. However, south of Alaska on the North American coast, fish are a negligible or extremely minor part of the sea otter's diet. Contrary to popular depictions, sea otters rarely eat starfish, and any kelp that is consumed apparently passes through the sea otter's system undigested.The individuals within a particular area often differ.

Sea otter. and not eat it. On land, young sea otters may face attack from bears and coyotes. In California, great white sharks are their primary predator but there is no evidence that the sharks eat them.Urban runoff transporting cat feces into the ocean brings "Toxoplasma gondii", an obligate parasite of felids, which has killed sea otters. Parasitic infections of "Sarcocystis neurona" are also associated with human activity. According to the U.S. Geological Survey and the CDC, northern sea otters off Washington have been infected with the H1N1 flu virus and "may be a newly identified animal host of influenza viruses".## Relationship.

Sea otter. with humans.## Fur trade.Sea otters have the thickest fur of any mammal, which makes them a common target for many hunters. Archaeological evidence indicates that for thousands of years, indigenous peoples have hunted sea otters for food and fur. Large-scale hunting, part of the Maritime Fur Trade, which would eventually kill approximately one million sea otters, began in the 18th century when hunters and traders began to arrive from all over the world to meet foreign demand for otter pelts, which were one of the world's most valuable types of fur.In the early 18th century, Russians began to hunt sea.

Sea otter. otters in the Kuril Islands and sold them to the Chinese at Kyakhta. Russia was also exploring the far northern Pacific at this time, and sent Vitus Bering to map the Arctic coast and find routes from Siberia to North America. In 1741, on his second North Pacific voyage, Bering was shipwrecked off Bering Island in the Commander Islands, where he and many of his crew died. The surviving crew members, which included naturalist Georg Steller, discovered sea otters on the beaches of the island and spent the winter hunting sea otters and gambling with otter pelts. They returned to.

Sea otter. Siberia, having killed nearly 1,000 sea otters, and were able to command high prices for the pelts. Thus began what is sometimes called the "Great Hunt", which would continue for another hundred years. The Russians found the sea otter far more valuable than the sable skins that had driven and paid for most of their expansion across Siberia. If the sea otter pelts brought back by Bering's survivors had been sold at Kyakhta prices they would have paid for one tenth the cost of Bering's expedition.Russian fur-hunting expeditions soon depleted the sea otter populations in the Commander Islands, and by.

Sea otter. 1745, they began to move on to the Aleutian Islands. The Russians initially traded with the Aleuts inhabitants of these islands for otter pelts, but later enslaved the Aleuts, taking women and children hostage and torturing and killing Aleut men to force them to hunt. Many Aleuts were either murdered by the Russians or died from diseases the hunters had introduced. The Aleut population was reduced, by the Russians' own estimate, from 20,000 to 2,000. By the 1760s, the Russians had reached Alaska. In 1799, Tsar Paul I consolidated the rival fur-hunting companies into the Russian-American Company, granting it an.

Sea otter. imperial charter and protection, and a monopoly over trade rights and territorial acquisition.Under Aleksander I, the administration of the merchant-controlled company was transferred to the Imperial Navy, largely due to the alarming reports by naval officers of native abuse; in 1818, the indigenous peoples of Alaska were granted civil rights equivalent to a townsman status in the Russian Empire.Other nations joined in the hunt in the south. Along the coasts of what is now Mexico and California, Spanish explorers bought sea otter pelts from Native Americans and sold them in Asia. In 1778, British explorer Captain James Cook reached Vancouver.

Sea otter. Island and bought sea otter furs from the First Nations people. When Cook's ship later stopped at a Chinese port, the pelts rapidly sold at high prices, and were soon known as "soft gold". As word spread, people from all over Europe and North America began to arrive in the Pacific Northwest to trade for sea otter furs.Russian hunting expanded to the south, initiated by American ship captains, who subcontracted Russian supervisors and Aleut hunters in what are now Washington, Oregon, and California. Between 1803 and 1846, 72 American ships were involved in the otter hunt in California, harvesting an.

Sea otter. estimated 40,000 skins and tails, compared to only 13 ships of the Russian-American Company, which reported 5,696 otter skins taken between 1806 and 1846. In 1812, the Russians founded an agricultural settlement at what is now Fort Ross in northern California, as their southern headquarters.Eventually, sea otter populations became so depleted, commercial hunting was no longer viable. It had stopped in the Aleutian Islands, by 1808, as a conservation measure imposed by the Russian-American Company. Further restrictions were ordered by the company in 1834. When Russia sold Alaska to the United States in 1867, the Alaska population had recovered to.

Sea otter. over 100,000, but Americans resumed hunting and quickly extirpated the sea otter again. Prices rose as the species became rare. During the 1880s, a pelt brought $105 to $165 in the London market, but by 1903, a pelt could be worth as much as $1,125. In 1911, Russia, Japan, Great Britain (for Canada) and the United States signed the Treaty for the Preservation and Protection of Fur Seals, imposing a moratorium on the harvesting of sea otters. So few remained, perhaps only 1,000–2,000 individuals in the wild, that many believed the species would become extinct.## Recovery and conservation.During the 20th.

Sea otter. Soviet Union in 1991; however, it has declined significantly with stricter law enforcement and better economic conditions.The most significant threat to sea otters is oil spills, to which they are particularly vulnerable, since they rely on their fur to keep warm. When their fur is soaked with oil, it loses its ability to retain air, and the animals can quickly die from hypothermia. The liver, kidneys, and lungs of sea otters also become damaged after they inhale oil or ingest it when grooming. The Exxon Valdez oil spill of 24 March 1989 killed thousands of sea otters in Prince William.

Sea otter. an oil spill wiping out a population. However, because of the species' reputation for depleting shellfish resources, advocates for commercial, recreational, and subsistence shellfish harvesting have often opposed allowing the sea otter's range to increase, and there have even been instances of fishermen and others illegally killing them.In the Aleutian Islands, a massive and unexpected disappearance of sea otters has occurred in recent decades. In the 1980s, the area was home to an estimated 55,000 to 100,000 sea otters, but the population fell to around 6,000 animals by 2000. The most widely accepted, but still controversial, hypothesis is that killer.

Sea otter. whales have been eating the otters. The pattern of disappearances is consistent with a rise in predation, but there has been no direct evidence of orcas preying on sea otters to any significant extent.Another area of concern is California, where recovery began to fluctuate or decline in the late 1990s. Unusually high mortality rates amongst adult and subadult otters, particularly females, have been reported. In 2017 the US Geological Survey found a 3% drop in the sea otter population of the California coast. This number still keeps them on track for removal from the endangered species list, although just barely.

Sea otter. States, Russia and Canada. In marine protected areas, polluting activities such as dumping of waste and oil drilling are typically prohibited. An estimated 1,200 sea otters live within the Monterey Bay National Marine Sanctuary, and more than 500 live within the Olympic Coast National Marine Sanctuary.## Economic impact.Some of the sea otter's preferred prey species, particularly abalone, clams, and crabs, are also food sources for humans. In some areas, massive declines in shellfish harvests have been blamed on the sea otter, and intense public debate has taken place over how to manage the competition between sea otters and humans for.

Sea otter. greatly depleted, no longer rely as intimately on sea mammals for survival.Since the mid-1970s, the beauty and charisma of the species have gained wide appreciation, and the sea otter has become an icon of environmental conservation. The round, expressive face and soft, furry body of the sea otter are depicted in a wide variety of souvenirs, postcards, clothing, and stuffed toys.## Aquariums and zoos.Sea otters can do well in captivity, and are featured in over 40 public aquariums and zoos. The Seattle Aquarium became the first institution to raise sea otters from conception to adulthood with the birth of Tichuk.

Sea otter. in 1979, followed by three more pups in the early 1980s. In 2007, a YouTube video of two sea otters holding paws drew 1.5 million viewers in two weeks, and had over 22 million views . Filmed five years previously at the Vancouver Aquarium, it was YouTube's most popular animal video at the time, although it has since been surpassed. The lighter-colored otter in the video is Nyac, a survivor of the 1989 "Exxon Valdez" oil spill. Nyac died in September 2008, at the age of 20. Milo, the darker one, died of lymphoma in January 2012.

Claviceps purpurea. Claviceps purpurea is an ergot fungus that grows on the ears of rye and related cereal and forage plants. Consumption of grains or seeds contaminated with the survival structure of this fungus, the ergot sclerotium, can cause ergotism in humans and other mammals. "C. purpurea" most commonly affects outcrossing species such as rye (its most common host), as well as triticale, wheat and barley. It affects oats only rarely.## Life cycle.An "ergot kernel" called "Sclerotium clavus" develops when a floret of flowering grass or cereal is infected by an ascospore of "C. purpurea". The infection process mimics a pollen grain.

Claviceps purpurea. growing into an ovary during fertilization. Because infection requires access of the fungal spore to the stigma, plants infected by "C. purpurea" are mainly outcrossing species with open flowers, such as rye ("Secale cereale") and Alopecurus.The proliferating fungal mycelium then destroys the plant ovary and connects with the vascular bundle originally intended for feeding the developing seed. The first stage of ergot infection manifests itself as a white soft tissue (known as "Sphacelia segetum") producing sugary honeydew, which often drops out of the infected grass florets. This honeydew contains millions of asexual spores (conidia) which are dispersed to other florets.

Claviceps purpurea. by insects or rain. Later, the "Sphacelia segetum" convert into a hard dry "Sclerotium clavus" inside the husk of the floret. At this stage, alkaloids and lipids (e.g. ricinoleic acid) accumulate in the Sclerotium.When a mature "Sclerotium" drops to the ground, the fungus remains dormant until proper conditions trigger its fruiting phase (onset of spring, rain period, need of fresh temperatures during winter, etc.). It germinates, forming one or several fruiting bodies with head and stipe, variously colored (resembling a tiny mushroom). In the head, threadlike sexual spores (ascospores) are formed in perithecia, which are ejected simultaneously, when suitable grass.

Claviceps purpurea. hosts are flowering. Ergot infection causes a reduction in the yield and quality of grain and hay produced, and if infected grain or hay is fed to livestock it may cause a disease called ergotism."Polistes dorsalis", a species of social wasps, have been recorded as a vector of the spread of this particular fungus. During their foraging behavior, particles of the fungal conidia get bound to parts of this wasp's body. As "P. dorsalis" travels from source to source, it leaves the fungal infection behind. Insects, including flies and moths, have also been shown to carry conidia of "Claviceps" species,.

Claviceps purpurea. but if insects play a role in spreading the fungus from infected to healthy plants is unknown.## Intraspecific variations.Early scientists have observed "Claviceps purpurea" on other Poaceae as "Secale cereale". 1855, Grandclement described ergot on "Triticum aestivum". During more than a century scientists aimed to describe specialized species or specialized varieties inside the species "Claviceps purpurea". "Claviceps microcephala" Tul. (1853) "Claviceps wilsonii" Cooke (1884)Later scientists tried to determine host varieties as "Claviceps purpurea" var. "agropyri" "Claviceps purpurea" var. "purpurea" "Claviceps purpurea" var. "spartinae" "Claviceps purpurea" var. "wilsonii".Molecular biology has not confirmed this hypothesis but has distinguished three groups differing in.

Claviceps purpurea. their ecological specificity. G1—land grasses of open meadows and fields; G2—grasses from moist, forest, and mountain habitats; G3 ("C. purpurea" var. "spartinae")—salt marsh grasses (Spartina, Distichlis).Morphological criteria to distinguish different groups: The shape and the size of sclerotia are not good indicators because they strongly depend on the size and shape of the host floret. The size of conidia can be an indication but it is weak and it is necessary to pay attention to that, due to osmotic pressure, it varies significantly if the spores are observed in honeydew or in water. The sclerotial density can be used as.

Claviceps purpurea. purpurea" conspicuous on the heads of ryes and other such grains is known as ergot. Sclerotia germinate in spring after a period of low temperature. A temperature of 0-5 °C for at least 25 days is required. Water before the cold period is also necessary. Favorable temperatures for stroma production are in the range of 10-25 °C. Favorable temperatures for mycelial growth are in the range of 20-30 °C with an optimum at 25 °C.Sunlight has a chromogenic effect on the mycelium with intense coloration.## Effects.The disease cycle of the ergot fungus was first described in 1853, but the connection.

Claviceps purpurea. with ergot and epidemics among people and animals was reported already in a scientific text in 1676.The ergot sclerotium contains high concentrations (up to 2% of dry mass) of the alkaloid ergotamine, a complex molecule consisting of a tripeptide-derived cyclol-lactam ring connected via amide linkage to a lysergic acid (ergoline) moiety, and other alkaloids of the ergoline group that are biosynthesized by the fungus. Ergot alkaloids have a wide range of biological activities including effects on circulation and neurotransmission.Ergotism is the name for sometimes severe pathological syndromes affecting humans or animals that have ingested ergot alkaloid-containing plant material, such as.

Claviceps purpurea. ergot-contaminated grains. Monks of the order of St. Anthony the Great specialized in treating ergotism victims with balms containing tranquilizing and circulation-stimulating plant extracts; they were also skilled in amputations. The common name for ergotism is "St. Anthony's Fire", in reference to monks who cared for victims as well as symptoms, such as severe burning sensations in the limbs. These are caused by effects of ergot alkaloids on the vascular system due to vasoconstriction of blood vessels, sometimes leading to gangrene and loss of limbs due to severely restricted blood circulation.The neurotropic activities of the ergot alkaloids may also cause.

Claviceps purpurea. hallucinations and attendant irrational behaviour, convulsions, and even death. Other symptoms include strong uterine contractions, nausea, seizures, and unconsciousness. Since the Middle Ages, controlled doses of ergot were used to induce abortions and to stop maternal bleeding after childbirth. Ergot alkaloids are also used in products such as Cafergot (containing caffeine and ergotamine or ergoline) to treat migraine headaches. Ergot extract is no longer used as a pharmaceutical preparation.Ergot contains no lysergic acid diethylamide (LSD) but rather ergotamine, which is used to synthesize lysergic acid, an analog of and precursor for synthesis of LSD. Moreover, ergot sclerotia naturally contain some.

Claviceps purpurea. amounts of lysergic acid.## Culture.Potato dextrose agar, wheat seeds or oat flour are suitable substrates for growth of the fungus in the laboratory.Agricultural production of Claviceps purpurea on rye is used to produce ergot alkaloids. Biological production of ergot alkaloids is also carried out by saprophytic cultivations.## Speculations.During the Middle Ages, human poisoning due to the consumption of rye bread made from ergot-infected grain was common in Europe. These epidemics were known as Saint Anthony's fire, or "ignis sacer".Gordon Wasson proposed that the psychedelic effects were the explanation behind the festival of Demeter at the Eleusinian Mysteries, where the initiates.

Caporael posited in 1976 that the hysterical symptoms of young women that had spurred the Salem witch trials had been the result of consuming ergot-tainted rye. However, her conclusions were later disputed by Nicholas P. Spanos and Jack Gottlieb, after a review of the historical and medical evidence. Other authors have likewise cast doubt on ergotism having been the cause of the Salem witch trials.The Great Fear in France during the Revolution has also been linked by some historians to the influence of ergot.British author John Grigsby claims that the presence of ergot in the stomachs of.

Claviceps purpurea. some of the so-called 'bog-bodies' (Iron Age human remains from peat bogs N E Europe such as Tollund Man), reveals that ergot was once a ritual drink in a prehistoric fertility cult akin to the Eleusinian Mysteries cult of ancient Greece. In his book Beowulf and Grendel he argues that the Anglo-Saxon poem Beowulf is based on a memory of the quelling of this fertility cult by followers of Odin. He states that Beowulf, which he translates as "barley-wolf", suggests a connection to ergot which in German was known as the 'tooth of the wolf'.An outbreak of violent hallucinations among.

Darapsa myron. Darapsa myron, the Virginia creeper sphinx, is a moth of the family Sphingidae found in central and eastern North America.## Distribution.It is found in southern Ontario and Quebec in Canada, and in the United States is found from Maine south to south Florida; west to North Dakota, Nebraska, New Mexico, Oklahoma, and Texas. It also can be found in Mexico.## Biology.There are 20 or 3 broods in much of the range, and larvae can mature in as few as 3 weeks. Larvae hide on the midribs of their host leaves and are nocturnal feeders. During July and August, this species.

Darapsa myron. is abundant in many areas, particularly Massachusetts and Pennsylvania. Adults emerge in the mid-afternoon and females begin calling bob after dusk. In spring, adults are more likely to feed, nectaring from flowers and drinking fluids from rotting fruit. In areas where they are common, D. myron readily come to both lights and sugar baits, being most active between sunset and midnight. Females have much rounder abdomens while the end of the male's abdomen is spade-shaped. Pairing is fairly quick and captive adults do not need to be fed, although females lay more eggs when fed. Sometimes adults refuse food altogether.Mated.

Darapsa myron. females deposit up to 150 small eggs that start out green but turn yellow within 48 hours, indicating fertility. Incubation lasts about 6 days. Full grown caterpillars poses the ability to chew though sleeves. Fully grown larvae turn a purplish brown before spinning a sparse, wiry cocoon among host leaves.

Cascabela thevetia. Cascabela thevetia (syn: "Thevetia peruviana") is a poisonous plant native throughout Mexico and in Central America, and cultivated widely as an ornamental. It is a relative of "Nerium oleander", giving it a common name yellow oleander, and is also called lucky nut in the West Indies.## Etymology.'Cascabel', 'cascavel' or 'cascabela' is Spanish for a small bell, a snake's rattle or a rattlesnake itself. The allusion may also be to the plant's toxicity comparable to the venom of a rattlesnake. The latin specific name "thevetia" commemorates André de Thevet (1516-1590), a French Franciscan priest and explorer, who explored Brazil and Guiana.

Cascabela thevetia. (where the plant is known as chapéu-de-napoleão, ie, Napoleon's hat).## Description."Cascabela thevetia" is an evergreen tropical shrub or small tree. Its leaves are willow-like, linear-lanceolate, and glossy green in color. They are covered in waxy coating to reduce water loss (typical of oleanders). Its stem is green turning silver/gray as it ages. Flowers bloom from summer to fall. The long funnel-shaped sometimes-fragrant yellow (less commonly apricot, sometimes white) flowers are in few-flowered terminal clusters. Its fruit is deep red-black in color encasing a large seed that bears some resemblance to a 'Chinese lucky nut.'"Cascabela thevetia" is commonly known as Kaneir.

Cascabela thevetia. or Kaner (कनेर) in Hindi language in India. It is effectively drought resistant and tolerant to high temperatures, hence found in various states of India like Andhra, Bihar, Delhi, Gujarat, Madhya Pradesh, Telangana, West Bengal, Rajasthan, Tamil Nadu, Uttar Pradesh , Odisha and Assam where semi arid climate is prevalent.## Religious importance.Its bright yellow flowers are used for religious purposes in India. The tree is native to Mexico and thus direct references to Hindu culture are new.## Toxicity.All parts of the "C. thevetia" plant are toxic to most vertebrates as they contain cardiac glycosides. Many cases of intentional and accidental.

Cascabela thevetia. poisoning of humans are known.The main toxins are the cardenolides called thevetin A and thevetin B; others include peruvoside, neriifolin, thevetoxin and ruvoside. These cardenolides are not destroyed by drying or heating and they are very similar to digoxin from "Digitalis purpurea". They produce gastric and cardiotoxic effects. Antidotes for treatment include atropine and digoxin immune fabs (antibodies) and treatment may include oral administration of activated charcoal. Ovine polyclonal anti-digitoxin Fab fragment antibody (DigiTAb; Therapeutic Antibodies Inc.) can be used to treat "T. peruviana" poisoning, but for many countries the cost is prohibitive.A few bird species are however known to.

Cascabela thevetia. feed on them without any ill effects. These include the sunbirds, Asian koel, red-whiskered bulbul, white-browed bulbul, red-vented bulbul, brahminy myna, common myna and common grey hornbill.In South India and in Sri Lanka swallowing the seeds of "Thevetia peruviana" (Kaneru කණේරු (Sinhala), Manjal arali (Tamil)) is one of the preferred methods for suicides in villages where they are grown in abundance.Extracts from "C. thevetia" are reported to possess antispermatogenic activity in rats.Cultivation## Uses."Cascabela thevetia" is cultivated as an ornamental plant, and planted as large flowering shrub or small ornamental tree standards in gardens and parks in temperate climates. In frost.

Lycosa tarantula. Lycosa tarantula is the species originally known as the tarantula, a name that nowadays in English commonly refers to spiders in another family entirely, the Theraphosidae. It now may be better called the tarantula wolf spider, being in the wolf spider family, the Lycosidae. "L. tarantula" is a large species found in southern Europe, especially in the Apulia region of Italy and near the city of Taranto, from which it gets its name.Historical superstition has it that the spider's bite can produce severe symptoms called tarantism.## Description.These spiders are rather large, the females being as large as 30 mm (1.18.

Lycosa tarantula. in) in body length and the males around 19 mm (0.75 in). As with other wolf spiders, the silken sac containing over 100 eggs is carried attached to the mother's spinnerets, and then after they hatch, the spiderlings climb on their mother's abdomen and ride around with her for some time until they are sufficiently mature to survive on their own. After leaving their mother's protection, the young spiders disperse and dig burrows. Females live in their burrows all their lives except for nocturnal forays to capture prey, but the mature males leave the protection of burrows and wander about.

Lycosa tarantula. looking for mates. The males can live for 2 years. The females can live for 4 years or more. Many sexual encounters (about one-third according to one study) end in the female's cannibalising the male instead. During the winter, these spiders hibernate in their burrows.They are a nocturnal species and generally lurk at the mouths of their burrows waiting for prey, so people are unlikely to encounter them. Unlike the Salticidae (jumping spiders), which may exhibit curiosity about humans and may be content to wander around on one's hand, the Lycosidae (wolf spiders) have a very strong tendency to flee.

Lycosa tarantula. at the approach of any large animal. They have quite good eyesight, so a human likely cannot approach them unseen, and capturing them is relatively difficult because they keep moving and can run very fast. When wolf spiders are cornered, they show no inclination to make threat displays, much less to advance on a human's hand with the intention of biting.## Taxonomy.The species was first described by Carl Linnaeus in 1758 (as "Aranea tarantula"). It was transferred to the genus "Lycosa" by Pierre André Latreille in 1806. Charles Athanase Walckenaer in the same 1806 publication described the subspecies "narbonensis", which.

Lycosa tarantula. in 1837 he raised to a full species as "Lycosa narbonensis". A molecular phylogenetic study in 2013 showed that specimens assigned to this taxon were not genetically different from "Lycosa tarantula", so that "L. narbonensis" is now treated as synonym of "L. tarantula".## Tarantism.A once-traditional belief among Apulian peasantry is that a person bitten by one of these spiders must be treated by indulging in a special kind of dancing. The dance, or some version of it, is now known as the tarantella. However, the bites of this spider are not known to cause severe symptoms in humans, much less.

Lycosa tarantula. endanger human life.## Venom.In common with all other spiders (except the Uloboridae) "L. tarantula" possesses venom, which is important to the spider as a means to kill its prey, and secondarily, to protect itself. Evolutionarily, the venoms were tailored for subduing insect prey, and mammal species can have vastly different reactions to the same spider venom. "L. tarantula" will rarely bite, unless continually provoked, and its venom is not particularly toxic to human beings, and is no more painful than the sting of a bee. Fabre, however, did demonstrate that an artificially administered tarantula bite can kill small mammals and.

Lycosa tarantula. birds.Given the low toxicity of wolf spider bites and the small likelihood of actually being bitten, medical research efforts have not been directed toward the bites of "L. tarantula".

Common eider. The common eider (pronounced ) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50 – 71 (cm) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to 113 (km/h).The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long.

Common eider. placed with two other species in the genus "Somateria" that was introduced in 1819 by the English zoologist William Leach. The genus name is derived from Ancient Greek : "sōma" "body" (stem "somat-") and : "erion" "wool". The specific "mollissimus" is Latin meaning "very soft". Both parts of the name refer to its down feathers.Six subspecies are recognised: "S. m. v-nigrum" Bonaparte & Gray, GR, 1855 – breeds in northeast Asia and Alaska; winters in the Bering Sea and the Aleutian Islands "S. m. borealis" (Brehm, CL, 1824) – breeds in northeast Canada, Greenland and Iceland; winters in the north.

Common eider. ecology.The common eider is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.## Social behaviour.Eiders are colonial breeders. They nest on coastal islands in colonies ranging in size of less than 100 to upwards of 15,000 individuals. Female eiders frequently exhibit a high degree of natal philopatry, where they return to breed on the same island where they were hatched. This can lead to a high degree of relatedness between individuals nesting on the same island, as well as the development of kin-based female social structures. This relatedness has likely played a.

Common eider. role in the evolution of co-operative breeding behaviours amongst eiders. Examples of these behaviours include laying eggs in the nests of related individuals and crèching, where female eiders team up and share the work of rearing ducklings.

Fossil remains of "Loxodonta" species have been excavated in Africa, dating to the Middle Pliocene.## Taxonomy.The first scientific description of the African elephant was written in 1797 by Johann Friedrich Blumenbach, who proposed the scientific name "Elephas africanus"."Loxodonte" was proposed as a generic name for the African elephant by Frédéric Cuvier in 1825. This name refers to the lozenge-shaped enamel of the molar teeth, which differs significantly from the rounded shape of.

African elephant. primarily by the trigeminal nerve, and thought to be manipulated by about 40,000–60,000 muscles. Because of this muscular structure, the trunk is so strong that elephants can use it for lifting about 3% of their own body weight. They use it for smelling, touching, feeding, drinking, dusting, producing sounds, loading, defending and attacking. Elephants sometimes swim underwater and use their trunks as snorkels.## Tusks and molars.Both male and female African elephants have tusks that grow from deciduous teeth called tushes, which are replaced by tusks when calves are about one year old. Tusks are composed of dentin, which forms small.

African elephant. diamond-shaped structures in the tusk's center that become larger at its periphery. Tusks are primarily used to dig for roots and strip the bark from trees for food, for fighting each other during mating season, and for defending themselves against predators. The tusks weigh from 23 (to(-)) and can be from 1.5 (to(-)) long. They are curved forward and continue to grow throughout the elephant's lifetime.The dental formula of elephants is . Elephants have four molars; each weighs about 5 (kg) and measures about 30 (cm) long. As the front pair wears down and drops out in pieces, the back.

At around 40 to 60 years of age, the elephant loses the last of its molars and will likely die of starvation which is a common cause of death. African elephants have 24 teeth in total, six on each quadrant of the jaw.

Their average sleep was found to be only 2 hours in 24-hour cycles.## Family.Both African elephant species live in family units comprising several adult cows, their daughters and their subadult sons. Each family unit is led by an older cow known as the matriarch. African forest elephant groups.

After puberty, male elephants tend to form close alliances with other males. While females are the most active members of African elephant groups, both male and female elephants are capable of distinguishing between hundreds of different low frequency infrasonic calls to communicate with and identify each other.Elephants use some vocalisations that are beyond the hearing range of humans, to communicate across large distances.

Falun Mine. Falun Mine (Swedish: "Falu Gruva") was a mine in Falun, Sweden, that operated for a millennium from the 10th century to 1992. It produced as much as two-thirds of Europe's copper needs and helped fund many of Sweden's wars in the 17th century. Technological developments at the mine had a profound influence on mining globally for two centuries. The mine is now a museum and in 2001 was designated a UNESCO World Heritage Site.## History.There are no written accounts establishing exactly when mining operations at Falun Mine began. Archaeological and geological studies indicate, with considerable uncertainty, that mining operations started.

Falun Mine. sometime around the year 1000. No significant activities had begun before 850, but the mine was definitely operating by 1080. Objects from the 10th century have been found containing copper from the mine. In the beginning, operations were of a small scale, with local farmers gathering ore, smelting it, and using the metal for household needs.Around the time of Magnus III, king of Sweden from 1275 to 1290, a more professional operation began to take place. Nobles and foreign merchants from Lübeck had taken over from farmers. The merchants transported and sold the copper in Europe but also influenced the.

Falun Mine. copper was heating the rock via large fires, known as fire-setting. When the rock cooled down, it would become brittle and crack, allowing manual tools such as wedges and sledge hammers to be brought to bear. After the ore had been transported out of the mine it was roasted to reduce sulfur content in open hearths. The thick, poisonous smoke produced would be a distinguishing feature of the Falun area for centuries. After the roasting, the ore was smelted; the output of which was a copper rich material. The cycle of roasting and smelting was repeated several times until crude.

Falun Mine. copper was produced. This was the final output from the mine; further refinement took place at copper refineries elsewhere. This process was used without any major change for seven centuries, until the end of the 19th century. It is likely that the methods and technology for fire-setting and drainage were imported from German mines, such as in the Harz Mountains.## Free miners.The organizational structure of Falun Mine created under the 1347 charter was advanced for its time. Free miners owned shares of the operation, proportional to their ownership of copper smelters. The structure was precursor to modern joint stock companies,.

Falun Mine. and Stora Enso, the modern successor to the old mining company, is often referred to as the oldest joint stock company still operational in the world.## Golden era.In the 17th century, production capacity peaked. During this time, the output from the mine was used to fund various wars of Sweden during its great power era. The Privy Council of Sweden referred to the mine as the nation's treasury and stronghold. The point of maximum production occurred in 1650, with over 3,000 tonnes of copper produced.The mountain had been mined for nearly half a millennium towards the end of its golden.

Falun Mine. is one of the great wonders of Sweden but as horrible as hell itself". Linnaeus' description of the environment the miners worked in is as follows: "Soot and darkness surrounded them on all sides. Stones, gravel, corrosive vitriol, drips, smoke, fumes, heat, dust, were everywhere".## Economic impact.Sweden had a virtual monopoly on copper which it retained throughout the 17th century. The only other country with a comparable copper output was Japan, but European imports from Japan were insignificant. In 1690, Erik Odhelius, a prominent metallurgist, was dispatched by the King to survey the European metal market. Although copper production had.

Falun Mine. already begun to decline by the time he made his report, something Odhelius made no secret of, he stated, "For the production of copper Sweden has always been like a mother, and although in many places within and without Europe some copper is extracted it counts for nothing next to the abundance of Swedish copper".By modern standards, however, the output was not large. Peak production barely reached 3,000 tonnes of copper per year, falling to less than 2,000 tonnes by 1665; from 1710 to 1720 it was barely 1,000 tonnes per year. Present worldwide copper production is 18.3 million tons.

Falun Mine. per year; Chuquicamata, a modern copper mine in Chile, has maintained an annual output exceeding 500,000 tonnes for decades.## Modern history.Copper production declined during the 18th century, and the mining company began diversifying. It supplemented copper extraction with iron and timber production. Production of the iconic falu red paint began in earnest. In the 19th century, iron and forest products continued to grow in their importance. In 1881 gold was discovered in Falun Mine, resulting in a short-lived gold rush. A total of 5 tonnes of gold would eventually be produced.By the late 20th century, the mine was no longer.

Schizachyrium scoparium, commonly known as little bluestem or beard grass, is a species of North American prairie grass native to most of the contiguous United States (except California, Nevada, and Oregon) as well as a small area north of the Canada–US border and northern Mexico. It is most common in the Midwestern prairies and is one of the most abundant native plants in Texas grasslands.Little bluestem is a perennial bunchgrass and is prominent in tallgrass prairie, along with big bluestem ("Andropogon gerardi"), indiangrass ("Sorghastrum nutans") and switchgrass ("Panicum virgatum"). It is a warm-season species, meaning it employs the C4 photosynthetic.

In July, it initiates flowering stalks, which reach four to five feet in height. In fall, it displays a coppery or mostly orange color with tints of red or purple. Sometimes it displays in some places, as in sandy soils, a redder fall color. It becomes a more orangish-bronze in winter until early spring, when it becomes more tan.## Cultivation.It is recommended for USDA zones 3 to 10.The plant grows best in.
