Pontederia crassipes. Pontederia crassipes (formerly "Eichhornia crassipes"), commonly known as common water hyacinth is an aquatic plant native to South America, naturalized throughout the world, and often invasive outside its native range. It is the sole species of the subgenus "Oshunae" within the genus "Pontederia". Anecdotally, it is known as the "terror of Bengal" due to its invasive growth tendencies.## Description.Water hyacinth is a free-floating perennial aquatic plant (or hydrophyte) native to tropical and sub-tropical South America. With broad, thick, glossy, ovate leaves, water hyacinth may rise above the surface of the water as much as 1 (m) in height. The leaves.

Pontederia crassipes. are 10–20 (cm) across on a stem which is floating by means of buoyant bulb-like nodules at its base above the water surface. They have long, spongy and bulbous stalks. The feathery, freely hanging roots are purple-black. An erect stalk supports a single spike of 8–15 conspicuously attractive flowers, mostly lavender to pink in colour with six petals. When not in bloom, water hyacinth may be mistaken for frog's-bit ("Limnobium spongia") or Amazon frogbit ("Limnobium laevigatum").One of the fastest-growing plants known, water hyacinth reproduces primarily by way of runners or stolons, which eventually form daughter plants. Each plant additionally can.

Pontederia crassipes. produce thousands of seeds each year, and these seeds can remain viable for more than 28 years. The common water hyacinth ("Pontederia crassipes") are vigorous growers and mats can double in size in one to two weeks. And in terms of plant count rather than size, they are said to multiply by more than a hundredfold in number, in a matter of 23 days.In their native range, these flowers are pollinated by long-tongued bees and they can reproduce both sexually and clonally. The invasiveness of the hyacinth is related to its ability to clone itself and large patches are likely.

Pontederia crassipes. to all be part of the same genetic form.Water hyacinth has three flower morphs and is termed "tristylous". The flower morphs are named for the length of their pistil: long, medium and short. Tristylous populations are however limited to the native lowland South America range of water hyacinth; in the introduced range, the M-morph prevails, with the L-morph occurring occasionally and the S-morph is absent altogether. This geographical distribution of the floral morphs indicates that founder events have played a prominent role in the species' worldwide spread.## Habitat and ecology.Its habitat ranges from tropical desert to subtropical or warm temperate.

Pontederia crassipes. desert to rainforest zones. The temperature tolerance of the water hyacinth is the following; its minimum growth temperature is 12 (C); its optimum growth temperature is 25 - 30 (C); its maximum growth temperature is 33 - 35 (C), and its pH tolerance is estimated at 5.0–7.5. Leaves are killed by frost and plants do not tolerate water temperatures > 34 (C). Water hyacinths do not grow where the average salinity is greater than 15% that of sea water (around 5 g salt per kg). In brackish water, its leaves show epinasty and chlorosis, and eventually die. Rafts of harvested.

Pontederia crassipes. water hyacinth have been floated to the sea where it is killed."Azotobacter chroococcum", a species of nitrogen-fixing bacteria, is probably concentrated around the bases of the petioles, but the bacteria do not fix nitrogen unless the plant is suffering extreme nitrogen deficiency.Fresh plants contain prickly crystals. This plant is reported to contain hydrogen cyanide, alkaloids, and triterpenoids, and may induce itching. Plants sprayed with 2,4-dichlorophenoxyacetic acid may accumulate lethal doses of nitrates, and other harmful elements in polluted environments.## Invasive species.Water hyacinth grows and reproduces quickly, so it can cover large portions of ponds and lakes. Particularly vulnerable are bodies.

Pontederia crassipes. of water that have already been affected by human activities, such as artificial reservoirs or eutrophied lakes that receive large amounts of nutrients. It outcompetes native aquatic plants, both floating and submerged. In 2011, Wu Fuqin et al. tracked the results of Yunnan Dianchi Lake and also showed that water hyacinth could affect the photosynthesis of phytoplankton, submerged plants and algae by water environment quality and inhibit its growth. The decay process depletes dissolved oxygen in the water, often killing fish.Water hyacinth can absorb a large amount of harmful heavy metals and other substances. After death, it will rot and.

Pontederia crassipes. sink to the bottom of the water, causing secondary pollution to the water body, destroying the natural water quality, and may even affect the quality of residents' drinking water in severe cases. Water where water hyacinth grows heavily is often a breeding place for disease vectors (e.g. mosquitoes and snails) and harmful pathogens, posing a potential threat to the health of local residents. On the other hand, water hyacinth can also provide a food source for goldfish, keep water clean and help to provide oxygen.The invasion of water hyacinth also has socioeconomic consequences. Since water hyacinth is comprised up of.

Pontederia crassipes. 95% water, the evapotranspiration rate is high. As such, small lakes that have been covered with the species can dry out and leave communities without adequate water or food supply. In some areas, dense mats of water hyacinth prevents the use of a waterway, leading to the loss of transportation (both human and cargo) as well as a loss of fishing possibilities. Large sums of money are allocated to the removal of water hyacinth from the water bodies as well as figuring out how to destroy the remains harvested. Harvesting water hyacinth mechanically requires a lot of effort. A million.

Pontederia crassipes. tons of fresh biomass would require 75 trucks with a capacity of 40m^3, per day, for 365 days to get rid of a million tons of water hyacinth. The water hyacinth would then be transferred to a dumping site and allowed to decompose which releases CO2, CH4 and nitrogen oxides which would all negatively impact the air quality and contribute to global warming.Water hyacinth has been widely introduced in North America, Europe, Asia, Australia, Africa, and New Zealand. In many areas, it has become an important and pernicious invasive species. In New Zealand, it is listed on the National Pest.

Pontederia crassipes. Plant Accord, which prevents it from being propagated, distributed, or sold. In large water areas such as Louisiana, the Kerala Backwaters in India, Tonlé Sap in Cambodia, and Lake Victoria, it has become a serious pest. The common water hyacinth has become an invasive plant species on Lake Victoria in Africa after it was introduced into the area in the 1980s.## United States.## Introduction into the U.S..Various accounts are given as to how the water hyacinth was introduced to the United States.The claim that the water hyacinth was introduced to the U.S. in 1884 at the World's Fair in New.

Pontederia crassipes. Orleans, also known as the World Cotton Centennial, has been characterized as the "first authentic account", as well as "local legend".At some time, versions of the "legend" asserted that the plants had been given away as a gift by a Japanese delegation at the fair. This claim is absent in a pertinent article published in a military engineer's trade journal dating to 1940, but appears in a piece penned in 1941 by the director of the wildlife and fisheries division at the Louisiana Department of Conservation, where the author writes, "the Japanese government maintained a Japanese building" at the fair,.

Pontederia crassipes. and the "Japanese staff imported from Venezuela considerable numbers of water hyacinth, which were given away as souvenirs". The claim has been repeated by later writers, with various shifts in the details. Thus NAS fellow Noel D. Vietmeyer (1975) wrote that "Japanese entrepreneurs" introduced the plant into the U.S., and the plants had been "collected from the Orinoco River in Venezuela", and the claim was echoed along the same gist by a pair of NASA researchers (), who asserted that the souvenir plants were carelessly dumped in various waterways. Canadian biologist Spencer C. H. Barrett (2004) meanwhile favored the theory.

Pontederia crassipes. they were first cultivated in garden ponds, after which they multiplied and escaped to the environs. The account gains a different detail as told by children's story-teller Carole Marsh (1992), who says "Japan gave away water hyacinth seeds" during the exposition, and another Southern raconteur, Gaspar J. "Buddy" Stall (1998) assured his readership that the Japanese gave each family a package of those seeds.One paper has also inquired into the role which catalog sales of seeds and plants may have played in the dissemination of invasive plants. It has been found that "P. crassipes" was offered in the 1884 issue.

Pontederia crassipes. of Bordentown, New Jersey-based Edmund D. Sturtevant's "Catalogue of rare water lilies and other choice aquatic plants", and of Germany has offered the plant since 1864 (since the firm was founded). By 1895, it was offered by seed-purveyors in the states of NJ, NY, California, and Florida.The "Harper's Weekly" magazine (1895) printed an anecdotal account stating that a certain man from New Orleans collected and brought home water hyacinths he collected from Colombia, c. 1892, and the plant proliferated in a matter of 2 years.## Infestation and control in the Southeast.As the hyacinths multiply into mats, they eliminate the presence.

Pontederia crassipes. of fish, and choke waterways for boating and shipping. This effect was well taking hold in the state of Louisiana by the turn of the 20th century.The plant invaded Florida in 1890, and an estimated 50 kg/m2 of the plant mass choked Florida's waterways. The clogging of the St. Johns River was posing a serious threat, and in 1897 the government dispatched a task force of the United States Army Corps of Engineers to solve the water hyacinth problem plaguing the Gulf states such as Florida and Louisiana.Thus in the early 20th century, the U.S. War Department (i.e., the Army.

Pontederia crassipes. Corps of Engineers) tested various means of eradicating the plants, including the jet-streaming of steam and hot water, application of various strong acids, and application of petroleum followed by incineration. Spraying with saturated salt solution (but not dilute solutions) effectively killed the plants; unfortunately this was considered prohibitively expensive, and the engineers selected Harvesta brand herbicide, whose active ingredient was arsenic acid, as the optimal cost-effective tool for eradication. This herbicide was used until 1905, when it was substituted with a different, white arsenic based compound. An engineer charged with the spraying did not think the poison to be a.

Pontederia crassipes. matter of concern, stating that the crew of the spraying boat would routinely catch fish from their working areas and consume them. However, spraying had little hope of completely eradicating the water hyacinth, due to the vastness of escaped colonies and the inaccessibility of some of the infested areas, and the engineer suggested that some biological means of control may be needed. In 1910, a bold solution was put forth by the New Foods Society. Their plan was to import and release hippopotamus from Africa into the rivers and bayous of Louisiana. The hippopotamus would then eat the water hyacinth.

Pontederia crassipes. and also produce meat to solve another serious problem at the time, the American meat crisis.Known as the American Hippo bill, H.R. 23621 was introduced by Louisiana Congressman Robert Broussard and debated by the Agricultural Committee of the U.S. House of Representatives. The chief collaborators in the New Foods Society and proponents of Broussard's bill were Major Frederick Russell Burnham, the celebrated American Scout, and Captain Fritz Duquesne, a South African Scout who later became a notorious spy for Germany. Presenting before the Agricultural Committee, Burnham made the point that none of the animals that Americans ate, chickens, pigs, cows,.

Pontederia crassipes. sheep, lambs, were native to the U.S.; all had been imported by European settlers centuries before, so why should Americans hesitate to introduce hippopotamus and other large animals into the American diet? Duquesne, who was born and raised in South Africa, further noted that European settlers on that continent commonly included hippopotamus, ostrich, antelope, and other African wildlife in their diets and suffered no ill effects. The American Hippo bill nearly passed, but fell one vote short.Water hyacinths have also been introduced into waters inhabited by manatees in Florida, for the purpose of bioremediation (cf. §Phytoremediation below) of the waters.

Pontederia crassipes. that have become contaminated and fallen victim to algal blooming. The manatees include the water hyacinth in their diet, but it may not be the food of first choice for them.## Legality of sale and shipment in the United States.In 1956 "E. crassipes" was banned for sale or shipment in the United States, subject to a fine and/or imprisonment. This law was repealed by HR133 [116th Congress (2019-2020)] on 12/27/2020.## Africa.The water hyacinth may have been introduced into Egypt in the late 18th to early 19th century during Muhammad Ali of Egypt's era, but was not recognized as an invasive.

Pontederia crassipes. threat until 1879. The invasion into Egypt is dated between 1879 and 1892 by Brij Gopal. Gopal; Junk; Davis (2000) ", Biodiversity in Wetlands" 2p. 109.</ref>The plant (Afrikaans: "waterhiasint") arguably invaded South Africa in 1910, although earlier dates have been claimed.The plant was introduced by Belgian colonists to Rwanda to beautify their holdings. It then advanced by natural means to Lake Victoria where it was first sighted in 1988. There, without any natural enemies, it has become an ecological plague, suffocating the lake, diminishing the fish reservoir, and hurting the local economies. It impedes access to Kisumu and other harbors.The.

Pontederia crassipes. water hyacinth has also appeared in Ethiopia, where it was first reported in 1965 at the Koka Reservoir and in the Awash River, where the Ethiopian Electric Light and Power Authority has managed to bring it under moderate control at considerable cost of human labor. Other infestations in Ethiopia include many bodies of water in the Gambela Region, the Blue Nile from Lake Tana into Sudan, and Lake Ellen near Alem Tena. By 2018, it has become a serious problem on Lake Tana in Ethiopia.The water hyacinth is also present on the Shire River in the Liwonde National Park in.

Pontederia crassipes. Malawi.## Asia.Water hyacinth was introduced to North America in 1884 and later to Asia, Africa, and Australia. Since there are no natural enemies in the new location, it can multiply quickly and cause disaster.The water hyacinth was introduced to Bengal, India because of its beautiful flowers and shapes of leaves, but turned out to be an invasive weed draining oxygen from the water bodies and resulted in devastation of fish stock. The water hyacinth was referred to as the "(Beautiful) Blue Devil" in Bengal, and "Bengal Terror" elsewhere in India; it was called "German weed" (Bengali: "Germani pana") in Bangladesh.

Pontederia crassipes. out of belief the German Kaiser submarine mission was involved in introducing them at the outbreak of World War I; and called "Japanese trouble" in Sri Lanka, due to the rumor that the British had planted them in order to entice Japanese aircraft to land on the insecure pads.In Bangladesh, projects have begun to utilize water hyacinth for the construction of floating vegetable gardens.Water hyacinth has also invaded the Tonlé Sap lake in Cambodia. An Osmose project in Cambodia is trying to fight it by having local people make baskets from it.The plant entered Japan in 1884 for horticultural appreciation,.

Pontederia crassipes. according to conventional wisdom, but a researcher devoted to the study of the plant has discovered that ukiyo-e artist Utagawa Kunisada (aka Utagawa Toyokuni III, d. 1865) produced a wood-block print featuring the water hyacinth, goldfish, and beautiful women, dated to 1855. The plant is floated on the water surface of filled (glassware) fishbowls, or glazed earthenware waterlily pots (hibachi pots serving as substitute).In the 1930s, water hyacinth was introduced into China as a feed, ornamental plant and sewage control plant, and it was widely planted in the south as an animal feed. Beginning in the 1980s, with the rapid.

Pontederia crassipes. development of China's inland industry, the eutrophication of inland waters has intensified. With the help of its efficient asexual reproduction and environmental adaptation mechanisms, water hyacinth has begun to spread widely in the river basin. The hyacinths blocked the river and hindered the internal water traffic. For example, many waterways in Zhejiang and other provinces were blocked by the rapidly growing water hyacinth. In addition, a large number of water hyacinths floating in the water will block sunlight from entering the water, and its decay consumes a lot of dissolved oxygen in the water, pollutes the water quality, and can.

Pontederia crassipes. kill other aquatic plants. The outbreak of water hyacinth has seriously affected the biodiversity of the local ecosystem and threatened the production, life and health of community residents.In Iraq, water hyacinth which was imported in the 1990s as a decorative plant, caused major problems for water supply systems and fishermen at the Euphrates.## Europe.In 2016, the European Union banned any sales of the water hyacinth in the EU. The species features on the list of Invasive Alien Species of Union Concern. This means that not only the sales but also importation, cultivation, or intentional release into the environment are forbidden.

Pontederia crassipes. in the whole of the European Union.## Oceania.In Papua New Guinea, water hyacinth blocked sunlight to other aquatic organisms, created habitat for malaria-carrying mosquitoes, clogged waterways to the point that boats could not get through and reduced the quality of water for purposes such as cooking, washing and drinking. People have lost income or even died due to being unable to travel to get food or medical care, or due to diseases from contaminated water or mosquitoes.## Control.Control depends on the specific conditions of each affected location such as the extent of water hyacinth infestation, regional climate, and proximity to.

Pontederia crassipes. human and wildlife.## Chemical control.Chemical control is the least used out of the three controls of water hyacinth, because of its long-term effects on the environment and human health. The use of herbicides requires strict approval from governmental protection agencies of skilled technician to handle and spray the affected areas. The use of chemical herbicides is only used in case of severe infiltration of water hyacinth. However, the most successful use of herbicides is when it is used for smaller areas of infestation of water hyacinth. This is because in larger areas, more mats of water hyacinths are likely to.

Pontederia crassipes. survive the herbicides and can fragment to further propagate a large area of water hyacinth mats. In addition, it is more cost-effective and less laborious than mechanical control. Yet, it can lead to environmental effects as it can penetrate into the ground water system and can affect not only the hydrological cycle within an ecosystem but also negatively affect the local water system and human health. It is also notable that the use of herbicides is not strictly selective of water hyacinths; keystone species and vital organisms such as microalgae can perish from the toxins and can disrupt fragile food.

Pontederia crassipes. webs.The chemical regulation of water hyacinths can be done using common herbicides such as 2,4-D, glyphosate, and diquat. The herbicides are sprayed on the water hyacinth leaves and leads to direct changes to the physiology of the plant. The use of the herbicide known as 2,4-D leads to the death of water hyacinth through inhibition of cell growth of new tissue and cellular apoptosis. It can take almost a two-week period before mats of water hyacinth are destroyed with 2, 4-D. Between 75000 and 150000 (acre) of water hyacinth and alligator weed are treated annually in Louisiana.The herbicide known as.

Pontederia crassipes. diquat is a liquid bromide salt that can rapidly penetrate the leaves of the water hyacinth and lead to immediate inactivity of plant cells and cellular processes. For the herbicide glyphosate, it has a lower toxicity than the other herbicides; therefore, it takes longer for the water hyacinth mats to be destroyed (about three weeks). The symptoms include steady wilting of the plants and a yellow discoloration of the plant leaves that eventually leads to plant decay.## Physical control.Physical control is performed by land-based machines such as bucket cranes, draglines, or boom or by water based machinery such as aquatic.

Pontederia crassipes. weed harvesters, dredges, or vegetation shredder. Mechanical removal is seen as the best short-term solution to the proliferation of the plant. A project on Lake Victoria in Africa used various pieces of equipment to chop, collect, and dispose of 1500 (ha) of water hyacinth in a 12-month period. It is, however, costly and requires the use of both land and water vehicles, but it took many years for the lake to become in poor condition and reclamation will be a continual process.It can have an annual cost from $6 million to $20 million and is only considered a short-term solution.

Pontederia crassipes. to a long-term problem. Another disadvantage with mechanical harvesting is that it can lead to further fragmentation of water hyacinths when the plants are broken up by spinning cutters of the plant-harvesting machinery. The fragments of water hyacinth that are left behind in the water can easily reproduce asexually and cause another infestation.However, transportation and disposal of the harvested water hyacinth is a challenge because the vegetation is heavy in weight. The harvested water hyacinth can pose a health risk to humans because of the plant's propensity for absorbing contaminants, and it is considered toxic to humans. Furthermore, the practice.

Pontederia crassipes. of mechanical harvesting is not effective in large-scale infestations of the water hyacinth, because this aquatic invasive species grows much more rapidly than it can be eliminated. Only 1 to 2 (acre) of water hyacinth can be mechanically harvested daily because of the vast amounts of water hyacinths in the environment. Therefore, the process is very time-intensive.## Biological control.As chemical and mechanical removal is often too expensive, polluting, and ineffective, researchers have turned to biological control agents to deal with water hyacinth. The effort began in the 1970s when USDA researchers released into the United States three species of weevil.

Pontederia crassipes. known to feed on water hyacinth, "Neochetina bruchi", "N. eichhorniae", and the water hyacinth borer "Sameodes albiguttalis". The weevil species were introduced into the Gulf Coast states, such as Louisiana, Texas, and Florida, where thousands of acres were infested by water hyacinth. It was found that a decade later in the 1980s that there was a decrease in water hyacinth mats by as much as 33%. However, because the life cycle of the weevils is ninety days, it puts a limitation on the use of biological predation to efficiently suppress water hyacinth growth. These organisms regulate water hyacinth by limiting.

Pontederia crassipes. water hyacinth size, its vegetative propagation, and seed production. They also carry microorganisms that can be pathological to the water hyacinth. These weevils eat stem tissue, which results in a loss of buoyancy for the plant, which will eventually sink. Although meeting with limited success, the weevils have since been released in many other countries. However, the most effective control method remains the control of excessive nutrients and prevention of the spread of this species.In May 2010, the USDA's Agricultural Research Service released "Megamelus scutellaris" as an additional biological control insect for the invasive water hyacinth species. "Megamelus scutellaris" is.

Pontederia crassipes. a small planthopper insect native to Argentina. Researchers have been studying the effects of the biological control agent in extensive host-range studies since 2006 and concluded that the insect is highly host-specific and will not pose a threat to any other plant population other than the targeted water hyacinth. Researchers also hope that this biological control will be more resilient than existing biological controls and the herbicides that are already in place to combat the invasive water hyacinth.Another insect being considered as a biological control agent is the semi-aquatic grasshopper "Cornops aquaticum". This insect is specific to the water hyacinth.

Pontederia crassipes. and its family, and besides feeding on the plant, it introduces a secondary pathogenic infestation. This grasshopper has been introduced into South Africa in controlled trials.The introduction of manatees into waterways was reportedly successful in controlling the plant's growth in Guyana.The Rhodes University Centre for Biological Control is rearing "Megamelus scutellaris" and the water hyacinth weevils "Neochetina eichhorniae" and "Neochetina bruchi" en masse for biological control at dams in South Africa; of importance is the Hartbeespoort Dam.The moth "Niphograpta albiguttalis" (Warren) (Lepidoptera: Pyralidae) has been introduced to North America, Africa and Australia. Larvae of this moth bore in the stems.

Pontederia crassipes. and flower buds of water hyacinth.## Uses.Since water hyacinth is so prolific, harvesting it for various uses also serves as a means of environmental control.## Bioenergy.Because of its extremely high rate of development, "Pontederia crassipes" is an excellent source of biomass. 1 (ha) of standing crop thus produces more than 70000 (m3/ha) of biogas (70% , 30% ). According to Curtis and Duke, 1 (kg) of dry matter can yield 370 (l) of biogas, giving a heating value of 22000 (kJ/m3) compared to pure methane (895 Btu/ft3)Wolverton and McDonald report approximately 0.2 (m3/kg) methane, indicating biomass requirements of 350 (t/ha).

Pontederia crassipes. to attain the 70000 (m3/ha ) yield projected by the National Academy of Sciences (Washington). Ueki and Kobayashi mention more than 200 (t/ha) per year. Reddy and Tucker found an experimental maximum of more than 1/2 (t/ha) per day.Bengali farmers collect and pile up these plants to dry at the onset of the cold season; they then use the dry water hyacinths as fuel. The ashes are used as fertilizer. In India, 1 (t) of dried water hyacinth yields about 50 liters ethanol and 200 kg residual fiber (7,700 Btu). Bacterial fermentation of 1 (t) yields 26,500 ft3 gas (600.

Pontederia crassipes. Btu) with 51.6% methane (), 25.4% hydrogen (), 22.1% carbon dioxide (), and 1.2% oxygen (). Gasification of 1 (t) dry matter by air and steam at high temperatures (800 (C)) gives about 40,000 ft3 (1,100 m3) natural gas (143 Btu/ft3) containing 16.6% , 4.8% , 21.7% (carbon monoxide), 4.1% , and 52.8% (nitrogen). The high moisture content of water hyacinth, adding so much to handling costs, tends to limit commercial ventures. A continuous, hydraulic production system could be designed, which would provide a better utilization of capital investments than in conventional agriculture, which is essentially a batch operation.The labor.

Pontederia crassipes. involved in harvesting water hyacinth can be greatly reduced by locating collection sites and processors on impoundments that take advantage of prevailing winds. Wastewater treatment systems could also favorably be added to this operation. The harvested biomass would then be converted to ethanol, biogas, hydrogen, gaseous nitrogen, and/or fertilizer. The byproduct water can be used to irrigate nearby cropland.## Phytoremediation, waste water treatment.Water hyacinth removes arsenic from arsenic-contaminated drinking water. It may be a useful tool in removing arsenic from tube well water in Bangladesh.Water hyacinth is also observed to enhance nitrification in wastewater treatment cells of living technology. Their.

Pontederia crassipes. root zones are superb micro-sites for bacterial communities.Water hyacinth is a common fodder plant in the third world especially Africa though excessive use can be toxic. It is high in protein (nitrogen) and trace minerals and the goat feces are a good source of fertilizer as well.Water hyacinth is reported for its efficiency to remove about 60–80% nitrogen and about 69% of potassium from water. The roots of water hyacinth were found to remove particulate matter and nitrogen in a natural shallow eutrophicated wetland.The plant is extremely tolerant of, and has a high capacity for, the uptake of heavy metals,.

Pontederia crassipes. including cadmium, chromium, cobalt, nickel, lead, and mercury, which could make it suitable for the biocleaning of industrial wastewater.The roots of "Pontederia crassipes" naturally absorb some organic compounds believed to be carcinogenic, in concentrations 10,000 times that in the surrounding water. Water hyacinths can be cultivated for waste water treatment (especially dairy waste water).In addition to heavy metals, "Pontederia crassipes" can also remove other toxins, such as cyanide, which is environmentally beneficial in areas that have endured gold-mining operations.Water hyacinth can take in and degrade ethion, a phosphorus pesticide.## Agriculture.In places where water hyacinth is invasive, overabundant, and in need.

Pontederia crassipes. of clearing away, these traits make it free for the harvesting, which makes it very useful as a source of organic matter for composting in organic farming. It is used internationally for fertilizer and as animal feed and silage for cattle, sheep, geese, pigs, and other livestock.In Bengal, India the "kachuri-pana" has been used primarily for fertilizer, compost or mulch, and secondarily as fodder for livestock and fish. In Bangladesh, farmers in the southwestern region cultivate vegetables on "floating gardens" usually with a bamboo-built frame base, with dried mass of water hyacinth covered in soil as bedding. As a large.

Pontederia crassipes. portion of cultivable land goes under water for months during monsoon in this low-lying region, farmers have grown this method for many decades now. The method of this agriculture is known by many names including "dhap chash" and "vasoman chash".In Kenya, East Africa, it has been used experimentally as organic fertilizer, although there is controversy stemming from the high alkaline pH value of the fertilizer.## Other uses.In various places in the world, the plant is used for making furniture, handbags, baskets, rope, and household goods/interior products (lampshades, picture frames) by businesses launched by NGOs and entrepreneurs.## Woven products.American-Nigerian Achenyo Idachaba.

Pontederia crassipes. has won an award for showing how this plant can be exploited for profit as woven procuts in Nigeria.## Paper.Though a study found water hyacinths of very limited use for paper production, they are nonetheless being used for paper production on a small scale. Goswami pointed out in his article that water hyacinth has the potential to make tough and strong paper. He found that adding water hyacinth pulp to the raw material of bamboo pulp for anti-grease paper can increase the physical strength of paper.## Edibility.The plant is used as a carotene-rich table vegetable in Taiwan. Javanese sometimes cook.

Pontederia crassipes. and eat the green parts and inflorescence. Vietnamese also cook the plant and sometimes add its young leaves and flower to their salads.## Medicinal use.In Kedah (Malaysia), the flowers are used for medicating the skin of horses. The species is a "tonic".## Potential as bioherbicidal agent.Water hyacinth leaf extract has been shown to exhibit phytotoxicity against another invasive weed "Mimosa pigra". The extract inhibited the germination of "Mimosa pigra" seeds in addition to suppressing the root growth of the seedlings. Biochemical data suggested that the inhibitory effects may be mediated by enhanced hydrogen peroxide production, inhibition of soluble peroxidase activity,.

Wolf. often processed carcasses, or that they competed with other carnivores and needed to consume their prey quickly. Compared with those found in the modern spotted hyena, the frequency and location of tooth fractures in these wolves indicates they were habitual bone crackers.Genomic studies suggest modern wolves and dogs descend from a common ancestral wolf population that existed 20,000 years ago. A 2021 study found that the Himalayan wolf and the Indian plains wolf are part of a lineage that is basal to other wolves and split from them 200,000 years ago. Other wolves appear to have originated in Beringia in.

Wolf. in diet between wolves living on different continents is based on the variety of hoofed mammals and of available smaller and domesticated prey.In North America, the wolf's diet is dominated by wild large hoofed mammals (ungulates) and medium-sized mammals. In Asia and Europe, their diet is dominated by wild medium-sized hoofed mammals and domestic species. The wolf depends on wild species, and if these are not readily available, as in Asia, the wolf is more reliant on domestic species. Across Eurasia, wolves prey mostly on moose, red deer, roe deer and wild boar. In North America, important range-wide prey are.

Wolf. elk, moose, caribou, white-tailed deer and mule deer. They also prey on bison and muskoxen. Wolves can digest their meal in a few hours and can feed several times in one day, making quick use of large quantities of meat. A well-fed wolf stores fat under the skin, around the heart, intestines, kidneys, and bone marrow, particularly during the autumn and winter.Nonetheless, wolves are not fussy eaters. Smaller-sized animals that may supplement their diet include rodents, rabbits, hares, insectivores and smaller carnivores. They frequently eat waterfowl and their eggs. When such foods are insufficient, they prey on lizards, snakes, frogs,.

Wolf. and large insects when available. Wolves in northern Minnesota prey on northern pike in freshwater streams. The diet of coastal wolves in Alaska includes 20% salmon, while those of coastal wolves in British Columbia includes 25% marine sources, and those on the nearby islands 75%.In Europe, wolves eat apples, pears, figs, melons, berries and cherries. In North America, wolves eat blueberries and raspberries. Wolves also eat grass, which may provide some vitamins, but is most likely used mainly to induce vomiting to rid themselves of intestinal parasites or long guard hairs. They are known to eat the berries of mountain-ash,.

Wolf. lily of the valley, bilberries, cowberries, European black nightshade, grain crops, and the shoots of reeds.In times of scarcity, wolves will readily eat carrion. In Eurasian areas with dense human activity, many wolf populations are forced to subsist largely on livestock and garbage. Prey in North America continue to occupy suitable habitats with low human density, the wolves eating livestock and garbage only in dire circumstances. Cannibalism is not uncommon in wolves during harsh winters, when packs often attack weak or injured wolves and may eat the bodies of dead pack members.## Interactions with other predators.Wolves typically dominate other canid.

Wolf. in the Russian Far East, where tigers significantly depress wolf numbers, sometimes to the point of localized extinction. Only human depletion of tiger numbers appears to protect wolves from competitive exclusion from them. With perhaps only four proven records of tigers killing wolves, these cases are rare; attacks appear to be competitive rather than predatory in nature.In Israel, Central Asia and India wolves may encounter striped hyenas, usually in disputes over carcasses. Striped hyenas feed extensively on wolf-killed carcasses in areas where the two species interact. One-to-one, hyenas dominate wolves, and may prey on them, but wolf packs can drive.

Wolf. better warmed by sunlight exposure, and the snow can thaw more quickly. Resting places, play areas for the pups, and food remains are commonly found around wolf dens. The odor of urine and rotting food emanating from the denning area often attracts scavenging birds like magpies and ravens. Though they mostly avoid areas within human sight, wolves have been known to nest near domiciles, paved roads and railways. During pregnancy, female wolves remain in a den located away from the peripheral zone of their territories, where violent encounters with other packs are less likely to occur.The gestation period lasts 62–75.

Wolf. Wolves have been killed while attempting to bring down bison, elk, moose, muskoxen, and even by one of their smallest hoofed prey, the white-tailed deer. With smaller prey like beaver, geese, and hares, there is no risk to the wolf. Although people often believe wolves can easily overcome any of their prey, their success rate in hunting hoofed prey is usually low.The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding. After chasing and then confronting a large prey animal, the.

Wolf. blood loss, thereby lessening the risk of injury to themselves. With medium-sized prey, such as roe deer or sheep, wolves kill by biting the throat, severing nerve tracks and the carotid artery, thus causing the animal to die within a few seconds to a minute. With small, mouselike prey, wolves leap in a high arc and immobilize it with their forepaws.Once prey is brought down, wolves begin to feed excitedly, ripping and tugging at the carcass in all directions, and bolting down large chunks of it. The breeding pair typically monopolizes food to continue producing pups. When food is scarce,.

Wolf. been recorded in Alaskan wolves, infections being most prevalent in winter months.Bacterial diseases carried by wolves include: brucellosis, Lyme disease, leptospirosis, tularemia, bovine tuberculosis, listeriosis and anthrax. Wolves can catch "Brucella suis" from wild and domestic reindeer. While adult wolves tend not to show any clinical signs, it can severely weaken the pups of infected females. Although lyme disease can debilitate individual wolves, it does not appear to significantly affect wolf populations. Leptospirosis can be contracted through contact with infected prey or urine, and can cause fever, anorexia, vomiting, anemia, hematuria, icterus, and death. Wolves living near farms are more.

Wolf. vulnerable to the disease than those living in the wilderness, probably because of prolonged contact with infected domestic animal waste. Wolves may catch tularemia from lagomorph prey, though its effect on wolves is unknown. Although bovine tuberculosis is not considered a major threat to wolves, it has been recorded to have killed two wolf pups in Canada.## Parasitic.Wolves carry ectoparasites and endoparasites; those in the former Soviet Union have been recorded to carry at least 50 species. Most of these parasites infect wolves without adverse effects, though the effects may become more serious in sick or malnourished specimens. Parasitic infection.

Wolf. spotted fever. The tick "Dermacentor pictus" also infests wolves. Other ectoparasites include chewing lice, sucking lice and the fleas "Pulex irritans" and "Ctenocephalides canis".Endoparasites known to infect wolves include: protozoans and helminths (flukes, tapeworms, roundworms and thorny-headed worms). Of 30,000 protozoan species, only a few have been recorded to infect wolves: "Isospora", "Toxoplasma", "Sarcocystis", "Babesia", and "Giardia". Some wolves carry "Neospora caninum", which can be spread to cattle and is correlated with bovine miscarriages. Among flukes, the most common in North American wolves is "Alaria", which infects small rodents and amphibians which are eaten by wolves. Upon reaching maturity, "Alaria.

Wolf. reactions, irritation of the intestinal mucosa, and malnutrition. Infections by the tapeworm "Echinococcus granulosus" in ungulate populations tend to increase in areas with high wolf densities, as wolves can shed "Echinoccocus" eggs in their feces onto grazing areas.Wolves can carry over 30 roundworm species, though most roundworm infections appear benign, depending on the number of worms and the age of the host. "Ancylostoma caninum" attaches itself on the intestinal wall to feed on the host's blood, and can cause hyperchromic anemia, emaciation, diarrhea, and possibly death. "Toxocara canis", a hookworm known to infect wolf pups in the uterus, can cause.

Wolf. Washington and Oregon. In Mexico and parts of the southwestern United States, the Mexican and U.S. governments collaborated from 1977 to 1980 in capturing all Mexican wolves remaining in the wild to prevent their extinction and established captive breeding programs for reintroduction.## Eurasia.Europe, excluding Russia, Belarus and Ukraine, has 17,000 wolves in more than 28 countries. In many countries of the European Union, the wolf is strictly protected under the 1979 Berne Convention on the Conservation of European Wildlife and Natural Habitats (AppendixII) and the 1992 Council Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Fauna and.

Wolf. numbers by destroying them throughout the year. Russian history over the past century shows that reduced hunting leads to an abundance of wolves. The Russian government has continued to pay bounties for wolves and annual harvests of 20–30% do not appear to significantly affect their numbers.In the Middle East, only Israel and Oman give wolves explicit legal protection. Israel has protected its wolves since 1954 and has maintained a moderately sized population of 150 through effective enforcement of conservation policies. These wolves have moved into neighboring countries. Approximately 300–600 wolves inhabit the Arabian Peninsula. The wolf also appears to be.

Wolf. are depicted as inhabitants of graveyards and destroyers of corpses.In the Pawnee creation myth, the wolf was the first animal brought to Earth. When humans killed it, they were punished with death, destruction and the loss of immortality. For the Pawnee, Sirius is the "wolf star" and its disappearance and reappearance signified the wolf moving to and from the spirit world. Both Pawnee and Blackfoot call the Milky Way the "wolf trail". The wolf is also an important crest symbol for clans of the Pacific Northwest like the Kwakwakaʼwakw.The concept of people turning into wolves, and the inverse, has been.

Wolf. present in many cultures. One Greek myth tells of Lycaon being transformed into a wolf by Zeus as punishment for his evil deeds. The legend of the werewolf has been widespread in European folklore and involves people willingly turning into wolves to attack and kill others. The Navajo have traditionally believed that witches would turn into wolves by donning wolf skins and would kill people and raid graveyards. The Dena'ina believed wolves were once men and viewed them as brothers.## In fable and literature.Aesop featured wolves in several of his fables, playing on the concerns of Ancient Greece's settled, sheep-herding.

Wolf. with a lamb in a utopian vision of the future. In the New Testament, Jesus is said to have used wolves as illustrations of the dangers his followers, whom he represents as sheep, would face should they follow him.Isengrim the wolf, a character first appearing in the 12th-century Latin poem "Ysengrimus", is a major character in the Reynard Cycle, where he stands for the low nobility, whilst his adversary, Reynard the fox, represents the peasant hero. Isengrim is forever the victim of Reynard's wit and cruelty, often dying at the end of each story. The tale of "Little Red Riding.

Wolf. Hood", first written in 1697 by Charles Perrault, is considered to have further contributed to the wolf's negative reputation in the Western world. The Big Bad Wolf is portrayed as a villain capable of imitating human speech and disguising itself with human clothing. The character has been interpreted as an allegorical sexual predator. Villainous wolf characters also appear in "The Three Little Pigs" and "The Wolf and the Seven Young Goats". The hunting of wolves, and their attacks on humans and livestock, feature prominently in Russian literature, and are included in the works of Leo Tolstoy, Anton Chekhov, Nikolay Nekrasov,.

Wolf. in amiable family groups and drawing on the experience of infirm but experienced elder pack members. Farley Mowat's largely fictional 1963 memoir "Never Cry Wolf" is widely considered to be the most popular book on wolves, having been adapted into a Hollywood film and taught in several schools decades after its publication. Although credited with having changed popular perceptions on wolves by portraying them as loving, cooperative and noble, it has been criticized for its idealization of wolves and its factual inaccuracies.## Conflicts.Human presence appears to stress wolves, as seen by increased cortisol levels in instances such as snowmobiling near.

Wolf. their territory.## Predation on livestock.Livestock depredation has been one of the primary reasons for hunting wolves and can pose a severe problem for wolf conservation. As well as causing economic losses, the threat of wolf predation causes great stress on livestock producers, and no foolproof solution of preventing such attacks short of exterminating wolves has been found. Some nations help offset economic losses to wolves through compensation programs or state insurance. Domesticated animals are easy prey for wolves, as they have been bred under constant human protection, and are thus unable to defend themselves very well. Wolves typically resort to.

Wolf. attacking livestock when wild prey is depleted. In Eurasia, a large part of the diet of some wolf populations consists of livestock, while such incidents are rare in North America, where healthy populations of wild prey have been largely restored.The majority of losses occur during the summer grazing period, untended livestock in remote pastures being the most vulnerable to wolf predation. The most frequently targeted livestock species are sheep (Europe), domestic reindeer (northern Scandinavia), goats (India), horses (Mongolia), cattle and turkeys (North America). The number of animals killed in single attacks varies according to species: most attacks on cattle and.

Wolf. horses result in one death, while turkeys, sheep and domestic reindeer may be killed in surplus. Wolves mainly attack livestock when the animals are grazing, though they occasionally break into fenced enclosures.## Competition with dogs.A review of the studies on the competitive effects of dogs on sympatric carnivores did not mention any research on competition between dogs and wolves. Competition would favour the wolf, which is known to kill dogs; however, wolves usually live in pairs or in small packs in areas with high human persecution, giving them a disadvantage when facing large groups of dogs.Wolves kill dogs on occasion,.

Wolf. and some wolf populations rely on dogs as an important food source. In Croatia, wolves kill more dogs than sheep, and wolves in Russia appear to limit stray dog populations. Wolves may display unusually bold behaviour when attacking dogs accompanied by people, sometimes ignoring nearby humans. Wolf attacks on dogs may occur both in house yards and in forests. Wolf attacks on hunting dogs are considered a major problem in Scandinavia and Wisconsin. The most frequently killed hunting breeds in Scandinavia are Harriers, older animals being most at risk, likely because they are less timid than younger animals, and react.

Wolf. to the presence of wolves differently. Large hunting dogs such as Swedish Elkhounds are more likely to survive wolf attacks because of their better ability to defend themselves.Although the number of dogs killed each year by wolves is relatively low, it induces a fear of wolves entering villages and farmyards to prey on them. In many cultures, dogs are seen as family members, or at least working team members, and losing one can lead to strong emotional responses such as demanding more liberal hunting regulations.Dogs that are employed to guard sheep help to mitigate human–wolf conflicts, and are often proposed.

Wolf. as one of the non-lethal tools in the conservation of wolves. Shepherd dogs are not particularly aggressive, but they can disrupt potential wolf predation by displaying what is to the wolf ambiguous behaviours, such as barking, social greeting, invitation to play or aggression. The historical use of shepherd dogs across Eurasia has been effective against wolf predation, especially when confining sheep in the presence of several livestock guardian dogs. Shepherd dogs are sometimes killed by wolves.## Attacks on humans.The fear of wolves has been pervasive in many societies, though humans are not part of the wolf's natural prey. How wolves.

Wolf. do not stop until the wolves involved are eliminated. Predatory attacks can occur at any time of the year, with a peak in the June–August period, when the chances of people entering forested areas (for livestock grazing or berry and mushroom picking) increase. Cases of non-rabid wolf attacks in winter have been recorded in Belarus, Kirov and Irkutsk oblasts, Karelia and Ukraine. Also, wolves with pups experience greater food stresses during this period. The majority of victims of predatory wolf attacks are children under the age of 18 and, in the rare cases where adults are killed, the victims are.

They are agile and speedy precocial birds.The drake has a low breathy call, and the hen a quiet trilling coo.The karyotype of the Muscovy duck is 2n=80, consisting of three pairs of macrochromosomes, 36 pairs of microchromosomes, and a pair of sex chromosomes. The two largest macrochromosome pairs are submetacentric, while all other chromosomes are acrocentric or probably telocentric for the smallest microchromosomes. The submetacentric chromosomes and the Z (female) chromosome show rather little constitutive heterochromatin (C bands), while the W chromosomes are at least two-thirds.

Muscovy duck. (note the submerged female in the image below). Domestic Muscovy ducks can breed up to three times each year.The hen lays a clutch of 8–16 white eggs, usually in a tree hole or hollow, which are incubated for 35 days. The sitting hen will leave the nest once a day from 20 minutes to one and a half hours, and will then defecate, drink water, eat and sometimes bathe. Once the eggs begin to hatch, it may take 24 hours for all the chicks to break through their shells. When feral chicks are born, they usually stay with their mother.

Grey plover. The grey plover or black-bellied plover (Pluvialis squatarola) is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.## Taxonomy.The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his "Systema Naturae" under the binomial name "Tringa squatarola". It is now placed with three other plovers in the genus "Pluvialis" that was introduced by the French onithologist Mathurin Jacques Brisson in 1760. The genus name is Latin and means relating to rain, from "pluvia", "rain". It was believed that they.

They moult to winter plumage in mid August to early September and retain this until April; this being a fairly plain grey above, with a grey-speckled breast and white belly. The juvenile and first-winter plumages, held by young birds from fledging until about one year old, are similar to the adult winter plumage but with the back feathers blacker with creamy white edging. In all plumages, the inner flanks and axillary feathers at the base of the underwing are black, a feature which readily distinguishes it from the other three "Pluvialis" species in flight. On the.

They nest on the ground in a dry open tundra with good visibility; the nest is a shallow gravel scrape. Four eggs (sometimes only three) are laid in early June, with an incubation period of 26–27 days; the chicks fledge when 35–45 days old.They migrate to winter in coastal areas throughout the world. In the New World they winter from.

The food consists of small molluscs, polychaete worms, crustaceans, and insects. It is less gregarious than the other "Pluvialis" species, not forming dense feeding flocks, instead feeding widely dispersed over beaches, with birds well spaced apart. They will however form dense flocks on high tide roosts.## Status.The International.

The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland.The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze Age figurines. It symbolised power, sexual potency and prowess in religions of the ancient Near East. Its horns were used in votive offerings, as trophies and drinking horns.Two aurochs domestication events occurred during the Neolithic Revolution.

Aurochs. in 1627 from natural causes.## Behaviour and ecology.Aurochs formed small herds mainly in winter, but lived singly or in smaller groups during the summer. If aurochs had social behaviour similar to their descendants, social status was gained through displays and fights, in which both cows and bulls engaged. With its hypsodont jaw, the aurochs was probably a grazer, with a food selection very similar to domesticated cattle feeding on grass, twigs and acorns.Mating season was in September, and calves were born in spring. The bulls had severe fights, and evidence from the Jaktorów forest shows these could lead to death.

Fire station. A fire station (also called a fire house, fire hall, firemen's hall, or engine house) is a structure or other area for storing firefighting apparatuses such as fire engines and related vehicles, personal protective equipment, fire hoses and other specialized equipment. Fire stations frequently contain working and living space for the firefighters and support staff.In large US cities, fire stations are often named for the primary fire companies and apparatus housed there, such as "Ladder 49". Other fire stations are named based on the district, neighborhood, town or village where they are located, or given a number.## Facilities.A fire station.

Fire station. dry to prevent rot. Historically, towers were lookouts for spotting fires.Activities at a fire station include regular inspection and cleaning of the apparatus and equipment, and training drills in which the firefighters practice their skills. Some fire companies also host public activities at the fire station during events such as a "fire prevention week", and the facility may also be used for fund-raising by the "firemen's association", "fire buffs", or "fire auxiliary".## Occupied stations.If the station is occupied full-time by career firefighters, it will contain living quarters and work areas, where they wait until a callout comes through.

Calocedrus decurrens. Calocedrus decurrens, with the common names incense cedar and California incense-cedar (syn. "Libocedrus decurrens" Torr.), is a species of coniferous tree native to western North America. It is the most widely known species in the genus, and is often simply called 'incense cedar' without the regional qualifier.## Description."Calocedrus decurrens" is a large tree, typically reaching heights of 30-40 (m) and a trunk diameter of up to 1.2 (m). The largest known tree, located in Klamath National Forest, Siskiyou County, California, is 47.98 (m) tall with a 12 (m) circumference trunk and a 17.5 (m) spread. Specimens form a broad conic.

Calocedrus decurrens. crown of spreading branches. The bark is orange-brown weathering grayish, smooth at first, becoming fissured and exfoliating in long strips on the lower trunk on old trees. Specimens can live to over 500 years old.The foliage is produced in flattened sprays with scale-like leaves 2–15 (mm) long; they are arranged in opposite decussate pairs, with the successive pairs closely then distantly spaced, so forming apparent whorls of four; the facial pairs are flat, with the lateral pairs folded over their bases. The leaves are bright green on both sides of the shoots, with only inconspicuous stomata. The foliage, when crushed,.

Calocedrus decurrens. gives off an aroma somewhat akin to shoe-polish.The seed cones are 20–35 (mm) long, pale green to yellow, with four (rarely six) scales arranged in opposite decussate pairs; the outer pair of scales each bears two winged seeds, the inner pair(s) usually being sterile and fused together in a flat plate. The cones turn orange to yellow-brown when mature about 8 months after pollination. The pollen cones are 6–8 (mm) long.## Distribution.The bulk of the tree's range is in the United States, from central-southwestern Oregon through most of California and the extreme west of Nevada, as well as a short.

Calocedrus decurrens. distance into northwest Mexico in northern Baja California.It grows at altitudes of 50-2900 (m).## Ecology.At lower elevations, associated trees include oaks and ponderosa pine. Giant sequoia bears similarities to the species, but has sharp leaves. In the south–southwest U.S. some have confused bushy junipers for incense cedar.With its thick basal bark, the incense cedar is one of the most fire- and drought-tolerant plants in California. Although the tree is killed by hot, stand-replacing crown fire, it spreads rapidly after lower-intensity burns. This has given the incense cedar a competitive advantage over other species such as the bigcone Douglas-fir in recent.

Calocedrus decurrens. years. Incense cedar is more shade tolerant than Douglas-fir, but not as much so as grand or white fir. It grows slowly when needed to outlast competition.This tree is the preferred host of a wood wasp, "Syntexis libocedrii" a species which lays its eggs in the smoldering wood immediately after a forest fire. The tree is also host to incense-cedar mistletoe ("Phoradendron libocedri"), a parasitic plant which can often be found hanging from its branches. Fire scars provide an entry point for "Tyromyces amarus" (pocket dry rot). "Gymnosporangium" rust disease afflicts the trees, but is rarely fatal.For numerous birds during.

Calocedrus decurrens. the wintertime, "Calocedrus decurrens" has been seen to be used for foraging. According to the United States Department of Agriculture, in areas of the Western Sierra Nevada in California, numerous species of birds are thought to use the incense cedar as a "foraging substrate" so that they can attain as much food as needed. Human impacts on these trees due to forest management practices have caused issues for many of these birds, threatening the use of the incense cedar as a forage substrate.## Uses.The wood is soft and light, and has a pleasant odor and is generally resistant to rot.

Calocedrus decurrens. It has been used for external house siding, interior paneling, and to make moth-resistant hope chests. It was once the primary material for wooden pencils, because it is soft and tends to sharpen easily without forming splinters.## Native Americans.Indigenous peoples of California use the plant in traditional medicine, basket making, hunting bows, building materials, and to produce fire by friction. A Northern California tribe used branchlets to filter out sand from water when leaching toxins from acorn meal; foliage also served as a flavoring.The Maidu Concow tribe name for the plant is hö'-tä (Konkow language).## Cultivation."Calocedrus decurrens" is cultivated as.

Pfäffikersee. Pfäffikersee (or "Lake Pfäffikon") is a lake in the canton of Zürich, Switzerland, near the town of Pfäffikon. It is 2.5 km long and 1.3 km wide at the middle. The lake was created in the last ice age when a moraine blocked off the ability for the lake to empty north towards Winterthur. There is also a hiking trail around the lake that people often bike and walk on, and the area is considered protected lands, among them the "Robenhauser Ried" and the prehistoric settlement Wetzikon–Robenhausen, discovered and researched by Jakob Messikommer (1828–1917), which became a serial site of.

Buchlovice Castle. Buchlovice Castle () is a chateau in Buchlovice in the Zlín Region of the Czech Republic. Its history is closely connected with nearby Buchlov Castle which grew more and more uncomfortable in the late 17th century, and that is why Jan Dětřich of Petřwald decided to build a new castle. Buchlovice Castle was built as a copy of an Italian villa in baroque style, by Domenico Martinelli. It is one of the most romantic buildings in this country. In 1800 it became property of the Berchtolds, and since 1945 the state castle is open to the public.## History.The area around.

Buchlovice Castle. Buchlovice was inhabited as early as the Stone Age, and the first written records of this district date from 1270. In 1540 Buchlovice became part of the estate of nearby Buchlov Castle. This medieval fortress, which did not meet the increasing demands for a comfortable and prestigious residence, ceased to suit its owners, who decided at the beginning of the 18th century to replace it with the grandiose castle in Buchlovice. Jan Dětrích of Petřvald had the castle built according to the proposals of Italian architect Domenico Martinelli between 1707 and 1738.The castle complex is made up the ceremonial building.

Great spotted woodpecker. excavate nest holes, and also drum for contact and territorial advertisement; like other woodpeckers, they have anatomical adaptations to manage the physical stresses from the hammering action. This species is similar to the Syrian woodpecker.This woodpecker occurs in all types of woodlands and eats a variety of foods, being capable of extracting seeds from pine cones, insect larvae from inside trees or eggs and chicks of other birds from their nests. It breeds in holes excavated in living or dead trees, unlined apart from wood chips. The typical clutch is four to six glossy white eggs. Both parents incubate the.

Great spotted woodpecker. eggs, feed the chicks, and keep the nest clean. When the young fledge they are fed by the adults for about ten days, each parent taking responsibility for feeding part of the brood.The species is closely related to some other members of its genus. It has a number of subspecies, some of which are distinctive enough to be potential new species. It has a huge range and large population, with no widespread threats, so it is classed as a species of least concern by the International Union for Conservation of Nature (IUCN).## Taxonomy.Woodpeckers are an ancient bird family consisting of.

Great spotted woodpecker. the nominate subspecies "D. m. major".The fossil subspecies "D. m. submajor" lived during the Middle Pleistocene Riss glaciation (250,000 to 300,000 years ago) when it was found in Europe south of the ice sheet. It is sometimes treated as a distinct species, but did not differ significantly from the extant great spotted woodpecker, whose European subspecies are probably its direct descendants.## Description.An adult great spotted woodpecker is 20 – 24 (cm) long, weighs 70 – 98 (g) and has a 34 – 39 (cm) wingspan. The upperparts are glossy blue-black, with white on the sides of the face and neck.

Great spotted woodpecker. were hatched, often as far as 100 – 600 (km), sometimes up to 3000 (km). Vagrants have reached the Faroe Islands, Hong Kong and Iceland, and there are several sightings from North America in at least the Aleutian Islands, Pribilof Islands and Alaska.Due to deforestation, this woodpecker was extirpated in Ireland in the seventeenth century, but the island has been naturally recolonised, with the first proven nesting in County Down in 2007. Its expansion in range is continuing, with breeding proven or suspected in at least 10 counties by 2013, with the main concentration in Down and County Wicklow. Genetic.

Great spotted woodpecker. against the shock of the impact when the bill is hammering on hard wood. The outer layer of the upper mandible is significantly longer than the more rigid lower mandible and absorbs much of the concussive force. Skeletal adaptations and strengthening also help to absorb the shock, and narrow nostrils protect against flying debris.As well as using holes for breeding, great spotted woodpeckers roost at night, and sometimes during the day, in old nest cavities, excavated by other woodpeckers. They will occasionally make a new roosting hole or use an artificial site such as a nest box.## Breeding.Great spotted woodpeckers.

Great spotted woodpecker. four to six glossy white eggs that measure 27 x 20 (mm) and weigh about 5.7 (g), of which 7% is shell. They are laid from mid-April to June, the later dates being for birds breeding in the north of the range or at altitude. The eggs are incubated by either adult during the day and by the male at night, for 10–12 days before hatching. Both birds brood and feed the altricial naked chicks and keep the nest clean. The young fledge in 20–23 days from hatching. Each parent then takes responsibility for feeding part of the brood for.

Great spotted woodpecker. about ten days, during which time they normally remain close to the nest tree.There is only one brood per year. The survival rates for adults and young are unknown, as is the average lifespan, but the maximum known age is just over 11 years.## Feeding.The great spotted woodpecker is omnivorous. It digs beetle larvae from trees and also takes many other invertebrates including adult beetles, ants and spiders. The bird also digs for Lepidoptera larvae like "Acronicta rumicis". Crustaceans, molluscs and carrion may be eaten, and bird feeders are visited for seeds, suet and domestic scraps. The nests of other.

Great spotted woodpecker. cavity-nesting birds, such as tits, may be raided for their eggs and chicks; nest boxes may be similarly attacked, holes being pecked to admit entrance by the woodpecker where necessary. House martin colonies can be destroyed in repeated visits.Fat-rich plant products such as nuts and conifer seeds are particularly important as winter food in the north of the woodpecker's range, and can then supply more than 30% of the bird's energy requirements. Other plant items consumed include buds, berries and tree sap, the latter obtained by drilling rings of holes around a tree trunk.The species feeds at all levels of.

Great spotted woodpecker. a tree, usually alone, but sometimes as a pair. It will use an "anvil" on which to hammer hard items, particularly pine, spruce, and larch cones, but also fruit, nuts, and hard-bodied insects.Easily accessible items are picked off the tree surface or from fissures in the bark, but larvae are extracted by chiselling holes up to 10 (cm) deep and trapping the soft insect with the tongue, which can extend to 40 (mm) beyond the bill, and is covered with bristles and sticky saliva to trap the prey. The woodpecker is able to extend its tongue so far because the.

Great spotted woodpecker. 73.7–110.3 million individuals, with 35% of the population in Europe. The breeding range is estimated as 57.8 (sqkm), and the population is considered overall to be large and apparently stable or slightly increasing, especially in Britain, where the population has recently overspilled into Ireland. For this reason the great spotted woodpecker is evaluated as a species of least concern by the IUCN.Breeding densities have been recorded as between 0.1–6.6 pairs/10 ha (0.04–2.7 pairs/10 acres), with the greatest densities in mature forest growing on alluvium. Numbers have increased in Europe due to the planting of forests, which provides breeding habitat, and.

Great spotted woodpecker. more available dead wood, and this species has profited from its flexibility with regard to types of woodland and its ability to thrive in proximity to humans. Harsh winters are a problem, and fragmentation of woodland can cause local difficulties. The Canary Islands populations of "D. m. canariensis" on Tenerife and "D. m. thanneri" on Gran Canaria face a potential threat from the exploitation of the local pine forests.

Green heron. The green heron (Butorides virescens) is a small heron of North and Central America. "Butorides" is from Middle English "butor" "bittern" and Ancient Greek "-oides", "resembling", and "virescens" is Latin for "greenish".It was long considered conspecific with its sister species the striated heron ("Butorides striata"), and together they were called "green-backed heron". Birds of the nominate subspecies (no matter which taxonomic arrangement is preferred) are extremely rare vagrants to western Europe—for example, a sighting in Pembrokeshire in 2018 was only the second recorded sighting in Wales; individuals from the Pacific coast of North America may similarly stray as far as.

Australian wood duck. The Australian wood duck, maned duck or maned goose ("Chenonetta jubata") is a dabbling duck found throughout much of Australia. It is the only living species in the genus Chenonetta. Traditionally placed in the subfamily Anatinae (dabbling ducks), it might belong to the subfamily Tadorninae (shelducks); the ringed teal may be its closest living relative.## Taxonomy.The Australian wood duck was first described by the English ornithologist John Latham in 1801 under the binomial name "Anas jubata".The flightless New Zealand species "Chenonetta finschi" (Finsch's duck) which was formerly believed to constitute a monotypic genus ("Euryanas") has been determined to belong to.

Australian wood duck. "Chenonetta". It became extinct before scientists could properly survey the New Zealand avifauna, but possibly as late as 1870 (based on a report of a flightless goose caught in Opotiki.)## Etymology."Chenonetta": "khēn", χηνος "khēnos" “goose”; νηττα "nētta" “duck”.<br>"jubata": “maned, crested”, from "iuba" “mane, crest”## Description.This 45–51 cm duck looks like a small goose, and mostly feeds by grazing in flocks.The male is grey with a dark brown head and mottled breast. The female has white stripes above and below the eye and mottled underparts. Both sexes have grey wings with black primaries and a white speculum. Juveniles are similar to.

The Australian wood duck is found in grasslands, open woodlands, wetlands, flooded pastures and along the coast in inlets and bays. It is also common on farmland with dams, as well as around rice fields, sewage ponds and in urban parks. It will often be found around deeper lakes that may be unsuitable for other waterbirds' foraging, as it prefers to forage on land. It has been recorded as a vagrant in New Zealand, although in 2015 and.

Staccato chattering is also present in flocks.## Protection.Australian wood duck is widespread in its geographic range and can be observed in a range of environments. This species has benefited from agriculture and urban developments due to the abundance of fresh water sources. In comparison to other species of Australian ducks, the Australian Wood Duck is very common in urban areas, especially near permanent water.

Waterbuck. 198 - 262 (kg) and females 161 - 214 (kg). Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55 - 99 (cm) long.Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits.
