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,.

Oudegracht. early canal (app. 1000) connecting the Rhine section to the river Vecht. The southern part was started in 1122, after the water level of the Rhine in Utrecht dropped because of the new dam at Wijk bij Duurstede. The ground excavated was used to raise the sides of the canal, to reduce the chance of flooding. When the city's system of locks was finished in 1275 the water level was constant, enabling the creation of permanently dry cellars and new quays at water level, hence the typical wharfs () below street level.

White-breasted nuthatch. The white-breasted nuthatch (Sitta carolinensis) is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 (cm) in length. Coloration varies somewhat along the species' range, but the are light blue-gray, with a black and nape in males, while females have a dark gray crown. The are whitish, with a reddish tinge on the lower abdomen. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a.

White-breasted nuthatch. slightly distinct distributions, vocalizations, and coloration. The species was once thought to be related to the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii"), two species from southern Asia, but is actually more closely related to the giant nuthatch ("S. magna"), also from Southeast Asia. The species enjoys a very wide distribution and its population is said to be increasing; the International Union for the Conservation of Nature therefore considers it to be of "least concern."## Taxonomy.The nuthatches are a genus, "Sitta", of small passerine birds which derive their English name from the tendency of some species to wedge.

White-breasted nuthatch. large insects or seeds into cracks, and then hack at them with their strong bills. "Sitta" is derived from "sittē", Ancient Greek for nuthatch, and "carolinensis" means "of Carolina" in Latin. The white-breasted nuthatch was first described by English ornithologist John Latham in his 1790 work, the "Index Ornithologicus". German ornithologist Hans Edmund Wolters proposed the division of the genus "Sitta" into subgenera in 1975–1982. The white-breasted nuthatch is placed in "Sitta" ("Leptositta") , alongside the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii").Nuthatch taxonomy is complex, with geographically separated species sometimes closely resembling each other. The white-breasted nuthatch.

White-breasted nuthatch. has an appearance and contact call similar to those of the white-cheeked nuthatch, of the Himalayas and was formerly considered to be conspecific with it. A study published in 2012 showed that four distinct lineages were genetically isolated from each other and could represent different species, recognizable by morphology and song. A molecular phylogeny published in 2014 and including all main species' lineages within nuthatches concluded that the white-breasted nuthatch was more closely related to the giant nuthatch ("S. magna") than to Przewalski's nuthatch, formerly regarded as possibly conspecific with it; Przewalski's nuthatch turned out to be basal in the.

White-breasted nuthatch. northeastern United States, at least 10% of females have black caps, but the proportion rises to 40–80% in the Rocky Mountains, Mexico and the southeastern U.S. Juveniles are similar to the adult, but duller plumaged.Three other, significantly smaller, nuthatches have ranges which overlap that of white-breasted, but none has white plumage completely surrounding the eye. Further distinctions are that the red-breasted nuthatch has a black eye line and reddish underparts, and the brown-headed and pygmy nuthatches each have a brown cap, and a white patch on the nape of the neck.## Geographical variation.The white-breasted nuthatch has nine subspecies, although the.

White-breasted nuthatch. differences are small and change gradually across the range. The subspecies are sometimes treated as three groups based on close similarities in morphology, habitat usage, and vocalizations. These groups cover eastern North America, the Great Basin and central Mexico, and the Pacific coastal regions. The subspecies of the western interior have the darkest upperparts, and eastern "S. c. carolinensis" has the palest back. The eastern form also has a thicker bill and broader dark cap stripe than the interior and Pacific races. The calls of the three groups differ, as described above.## Similar species.Only three other species of nuthatches inhabit.

White-breasted nuthatch. North America: the red-breasted nuthatch ("S. canadensis"), the pygmy nuthatch ("S. pygmaea") and the brown-headed nuthatch ("S. pusilla"), and their distributions overlap with those of the white-breasted nuthatch. They are, however, clearly distinct and much smaller, since they are the smallest nuthatches, measuring 10 centimeters long and weighing around 10 grams. The red-breasted nuthatch has reddish underparts and has a black stripe on the eye. The pygmy nuthatch and the brown-headed nuthatch have a brown crown with a white spot on the nape.## Distribution and habitat.The breeding habitat of the white-breasted nuthatch is woodland across North America, from southern Canada.

White-breasted nuthatch. pygmy and brown-headed nuthatches prefer pines.The presence of mature or decaying trees with holes suitable for nesting is essential, and trees such as oak, beech and hickory are favored in the east since they also provide edible seeds. White-breasted nuthatches seldom excavate their own nest holes like red-breasted nuthatches. Although suitable habitat is distributed continentally, it is discontinuous. The separate populations of this non-migratory species have diverged to form distinct regional subspecies.The white-breasted nuthatch, like most of its genus, is non-migratory, and the adults normally stay in their territory year-round. There may be more noticeable dispersal due to seed failure.

One bird landed on the RMS "Queen Mary" six hours' sailing east of New York City in October 1963.## Ecology and behavior.The white-breasted nuthatch often travels with small mixed flocks in winter. These flocks are led by titmice and chickadees, with nuthatches and downy woodpeckers as common attendant species. Participants in such flocks are thought to benefit in terms of foraging and predator avoidance. It is likely that the attendant species also access the information carried in.

White-breasted nuthatch. territory and either establish their own territory or become "floaters", unpaired birds without territories. It is probably these floaters which are mainly involved in the irregular dispersals of this species. This species of nuthatch roosts in tree holes or behind loose bark when not breeding and has the unusual habit of removing its feces from the roost site in the morning. It usually roosts alone except in very cold weather, when up to 29 birds have been recorded together.## Voice.Like other nuthatches, the white-breasted nuthatch is a noisy bird with a range of vocalizations. The male's mating song is a.

White-breasted nuthatch. strong legs and feet. All nuthatches are distinctive when seeking food because they are able to descend tree trunks head-first and can hang upside-down beneath twigs and branches.The white-breasted nuthatch is omnivorous, eating insects and seeds. It places large food items such as acorns or hickory nuts in crevices in tree trunks, and then hammers them open with its strong beak; surplus seeds are cached under loose bark or crevices of trees. The diet in winter may be nearly 70% seeds, but in summer it is mainly insects. The insects consumed by the white-breasted nuthatch include caterpillars, ants, and pest.

White-breasted nuthatch. species such as pine weevils, oystershell and other scale insects, and jumping plant lice. This bird will occasionally feed on the ground, and readily visits feeding stations for nuts, suet and sunflower seeds, the last of which it often takes away to store. The white-breasted nuthatch was also observed visiting raccoon latrines in order to find seeds.## Predators and parasites.Predators of adult nuthatches include owls and diurnal birds of prey (such as sharp-shinned and Cooper's hawks), and nestlings and eggs are eaten by woodpeckers, small squirrels, and climbing snakes such as the western rat snake. The white-breasted nuthatch responds to.

White-breasted nuthatch. and nine months.The white-breasted nuthatch's responses to predators may be linked to a reproductive strategy. A study compared the white-breasted nuthatch with the red-breasted nuthatch in terms of the willingness of males to feed incubating females on the nest when presented with models of predators. The models were of a sharp-shinned hawk, which hunts adult nuthatches, and a house wren, which destroys eggs. The white-breasted nuthatch is shorter-lived than the red-breasted nuthatch, but has more young, and was found to respond more strongly to the egg predator, whereas the red-breasted showed greater concern with the hawk. This supports the theory.

White-breasted nuthatch. for this species because it requires cavity sites for nesting; declines have been noted in Washington state, Florida, and more widely in the southeastern U.S. west to Texas. In contrast, the breeding range is expanding in Alberta, and numbers are increasing in the northeast due to regrown forest. The white-breasted nuthatch is protected under the Migratory Bird Treaty Act of 1918, to which the three countries in which it occurs (Canada, Mexico, and the United States) are all signatories.

Hippopotamus. The hippopotamus ( ; Hippopotamus amphibius), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis"). Its name comes from the ancient Greek for "river horse" ().Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises,.

Hippopotamus. etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1500 (kg) for bulls (males) and 1300 (kg) for cows (females). Despite its stocky shape and short legs, it is capable of running 30 (km/h) over short distances.Hippos inhabit rivers, lakes, and mangrove swamps. Territorial bulls each preside over a stretch of water and a group of five to thirty cows and calves. Mating and birth both occur in the water. During the day, hippos remain cool.

Hippopotamus. by staying in water or mud, emerging at dusk to graze on grasses. While hippos rest near each other in the water, grazing is a solitary activity and hippos typically do not display territorial behaviour on land. Hippos are among the most dangerous animals in the world due to their aggressive and unpredictable nature. They are threatened by habitat loss and poaching for their meat and ivory (canine teeth).## Etymology.The Latin word "hippopotamus" is derived from the ancient Greek , "hippopótamos", from , "híppos", 'horse', and , "potamós", 'river', meaning "horse of the river". In English, the plural is "hippopotamuses",.

Hippopotamus. but "hippopotami" is also used.## Taxonomy and origins.## Classification.The modern hippopotamus and the pygmy hippopotamus are the only living members of the family Hippopotamidae. Some taxonomists group hippos and anthracotheres in the superfamily Anthracotheroidea. Hippopotamidae are classified along with other even-toed ungulates in the order Artiodactyla.Five subspecies of hippos have been described based on morphological differences in their skulls as well as differences in geographical range:Great northern hippopotamus or Nile hippopotamus "H. a. amphibius" – (the nominate subspecies) which ranged from Egypt, where they are now extinct, south up the Nile River to Tanzania and MozambiqueEast African hippopotamus "H. a.

Hippopotamus. kiboko" – was present in Kenya in the African Great Lakes region, and in Somalia in the Horn of Africa. Featured broader nasals and a more hollowed interorbital regionCape hippopotamus or South African hippopotamus "H. a. capensis" – ranged from Zambia to South Africa; had the most flattened skull of the various subspeciesWest African hippopotamus or Tchad hippopotamus "H. a. tschadensis" – ranged throughout Western Africa to Chad, as the name suggests; featured a slightly shorter and wider face, with prominent orbitsAngola hippopotamus "H. a. constrictus" – ranged from the southern Democratic Republic of Congo to Angola and Namibia; named.

Hippopotamus. for its deeper preorbital constrictionThe suggested subspecies above were never widely used or validated by field biologists; the described morphological differences were small enough that they could have resulted from simple variation in nonrepresentative samples. Genetic analyses have tested the existence of three of these putative subspecies. A study examining mitochondrial DNA from skin biopsies taken from 13 sampling locations considered genetic diversity and structure among hippo populations across the continent. The authors found low, but significant, genetic differentiation among "H. a. amphibius", "H. a. capensis", and "H. a. kiboko". Neither "H. a. tschadensis" nor "H. a. constrictus" have been.

Hippopotamus. tested.## Evolution.Until 1909, naturalists classified hippos together with pigs based on molar patterns. Several lines of evidence, first from blood proteins, then from molecular systematics and DNA and the fossil record, show their closest living relatives are cetaceans (whales, dolphins, and porpoises). The common ancestor of hippos and whales branched off from Ruminantia and the rest of the even-toed ungulates; the cetacean and hippo lineages split soon afterwards.The most recent theory of the origins of Hippopotamidae suggests hippos and whales shared a common semiaquatic ancestor that branched off from other artiodactyls around . This hypothesised ancestral group likely split into.

Hippopotamus. two branches again around .One branch would evolve into cetaceans, possibly beginning about , with the protowhale "Pakicetus" and other early whale ancestors collectively known as Archaeoceti. This group eventually underwent aquatic adaptation into the completely aquatic cetaceans. The other branch became the anthracotheres, a large family of four-legged beasts, the earliest of which in the late Eocene would have resembled skinny hippos with comparatively small and narrow heads. All branches of the anthracotheres, except that which evolved into Hippopotamidae, became extinct during the Pliocene without leaving any descendants.A rough evolutionary lineage of the hippo can thus be traced from.

Hippopotamus. Eocene and Oligocene species: from "Anthracotherium" and "Elomeryx" to the Miocene species "Merycopotamus" and "Libycosaurus" and finally the very latest anthracotheres in the Pliocene. These groups lived in Eurasia, and the discovery of "Epirigenys" in East Africa, which was likely in a sister group to Hippopotamidae, suggests hippo ancestors entered Africa around and were the earliest large mammals to colonise the continent. An early hippopotamid is the genus "Kenyapotamus", which lived in Africa from 15 to . Hippopotamid species would spread across Africa and Eurasia, including the modern pygmy hippo. From 7.5 to , a possible ancestor to the modern.

Hippopotamus. hippo, "Archaeopotamus", lived in Africa and the Middle East.## Extinct species.Three species of Malagasy hippopotamus became extinct during the Holocene on Madagascar, the last of them within the past 1,000 years. The Malagasy hippos were smaller than the modern hippo, a likely result of the process of insular dwarfism. Fossil evidence indicates many Malagasy hippos were hunted by humans, a factor in their eventual extinction. Isolated individual Malagasy hippos may have survived in remote pockets; in 1976, villagers described a living animal called the "kilopilopitsofy", which may have been a Malagasy hippo.An extinct species, "Hippopotamus antiquus," ranged throughout Europe, extending.

Hippopotamus. as far north as Britain during the Early and Middle Pleistocene epochs, before being replaced by the modern "H. amphibius" during the latter part of the Middle Pleistocene. The Pleistocene also saw a number of dwarf species evolve on several Mediterranean islands, including Crete ("Hippopotamus creutzburgi"), Cyprus (the Cyprus dwarf hippopotamus, "Hippopotamus minor"), Malta ("Hippopotamus melitensis"), and Sicily ("Hippopotamus pentlandi"). Of these, the Cyprus dwarf hippo survived until the end of the Pleistocene or early Holocene. Evidence from the archaeological site Aetokremnos continues to cause debate on whether or not the species was driven to extinction, or even encountered, by.

Hippopotamus. man. Across Eurasia, the hippopotamus became extinct between 50,000 and 16,000 years ago.## Characteristics and adaptations.The hippopotamus is a megaherbivore and is exceeded in size among land animals only by elephants and some rhinoceros species. The mean adult weight is around 1480 (kg) for bulls and 1365 (kg) for cows. Exceptionally large males have been recorded reaching 2660 (kg). Male hippos appear to continue growing throughout their lives, while females reach maximum weight at around age 25. Hippos measure 2.90 to 5.05 (m) long, including a tail of about 35 to 56 (cm) in length and 1.30 to 1.65 (m).

Hippopotamus. tall at the shoulder, with males and females ranging 1.40 to 1.65 (m) and 1.30 to 1.45 (m) tall at the shoulder respectively. The species has a typical head-body length of 3.3 – 3.45 (m) and an average standing height of 1.4 (m) at the shoulder.Hippos have barrel-shaped bodies with short tails and legs, and an hourglass-shaped skull with a long muzzle. Their skeletal structures are graviportal, adapted to carrying their enormous weight, and their dense bones and low centre of gravity allows them to sink and move along the bottom of the water. Hippopotamuses have small legs (relative to.

Hippopotamus. other megafauna) because the water in which they live reduces the weight burden. The pelvis rests at an angle of 45 degrees. Though they are bulky animals, hippos can gallop at 30 (km/h) on land, but they normally trot. They are incapable of jumping but do climb up steep banks.The eyes, ears, and nostrils of hippos are placed high on the roof of their skulls. This allows these organs to remain above the surface while the rest of the body is submerged. Muscular closing valves exist in the nostrils while nictitating membranes cover the eyes. Despite being semiaquatic and having.

Hippopotamus. webbed feet, an adult hippo is not a particularly good swimmer, nor can it float. It is rarely found in deep water; when it is, the animal moves by porpoise-like leaps off the bottom. Adult hippos move at speeds of up to 8 (km/h) in water, typically resurfacing to breathe every three to five minutes. The young have to breathe every two to three minutes. The hippopotamus sleeps with both hemispheres of the brain resting, as in all land mammals. Despite this, it is able to sleep while submerged, intermittently surfacing to breathe seemingly without waking. They may be able.

Hippopotamus. to transition between different phases of sleep more quickly than other mammals.The hippo's jaw is powered by a large masseter and a well-developed digastric; the latter loops up behind the former to the hyoid. The jaw hinge is located far back enough to allow the animal to open its mouth at almost 180°. A folded orbicularis oris muscle allows the hippo to attain an extreme gape without tearing any tissue. Hippo teeth sharpen themselves as they grind together. The lower canines and lower incisors are enlarged, especially in bulls, and grow continuously. The incisors can reach 40 (cm), while the.

Hippopotamus. canines can grow to up to 50 (cm). The canines and incisors are used for combat and play no role in feeding. Hippos rely on their broad, rough lips to grasp and pull grasses which are then ground by the molars. The hippo is considered to be a pseudoruminant; it has a complex three-chambered stomach, but does not "chew cud".Unlike most other semiaquatic animals, hippos have very little hair. The skin is 6 (cm) thick, providing the hippo with great protection against predators and other hippos. By contrast, its subcutaneous fat layer is thin. The animals' upper parts are purplish-grey.

Hippopotamus. to blue-black, while the under parts and areas around the eyes and ears can be brownish-pink. Their skin secretes a natural, red-coloured sunscreen substance that is sometimes referred to as "blood sweat" but is neither blood nor sweat. This secretion is initially colourless and turns red-orange within minutes, eventually becoming brown. Two highly acidic pigments have been identified in the secretions; one red (hipposudoric acid) and one orange (norhipposudoric acid), which inhibit the growth of disease-causing bacteria and their light-absorption profile peaks in the ultraviolet range, creating a sunscreen effect. Regardless of diet, all hippos secrete these pigments so food.

Hippopotamus. does not appear to be their source; rather, they may be synthesised from precursors such as the amino acid tyrosine. This natural sunscreen cannot prevent the animal's skin from cracking if it stays out of water too long.The testes of the males descend only partially and a scrotum is not present. In addition, the penis retracts into the body when not erect. The genitals of the female hippos are unusual in that the vagina is ridged and two large diverticula protrude from the vulval vestibule. The function of these is unknown.A hippo's lifespan is typically 40 to 50 years. Donna.

Hippopotamus. the Hippo was one of the oldest living hippos in captivity. She lived at the Mesker Park Zoo in Evansville, Indiana, in the US until her death in 2012 at the age of 61. The oldest hippo ever recorded was called Bertha; she had lived in the Manila Zoo in the Philippines since it first opened in 1959. When she died in 2017, her age was estimated to be 65.## Distribution and status."Hippopotamus amphibius" was widespread in North Africa and Europe during the Eemian (130-115,000 years ago), with remains found as far north as England. Archaeological evidence exists of its.

Hippopotamus. presence in the Levant, dating to less than 3,000 years ago. The species was common in Egypt's Nile region during antiquity, but it has since been driven out. According to Pliny the Elder, in his time, the best location in Egypt for capturing this animal was in the Saite nome; the animal could still be found along the Damietta branch of the Nile after the Arab Conquest in 639. Reports of the slaughter of the last hippo in Natal Province were made at the end of the 19th century. Hippos are still found in the rivers and lakes of the.

Hippopotamus. northern Democratic Republic of the Congo, Uganda, Tanzania, and Kenya, north through to Ethiopia, Somalia, and Sudan, west to The Gambia, and south to South Africa.Genetic evidence suggests common hippos in Africa experienced a marked population expansion during or after the Pleistocene, attributed to an increase in water bodies at the end of the era. These findings have important conservation implications, as hippo populations across the continent are currently threatened by loss of access to fresh water. Hippos are also subject to unregulated hunting and poaching. The species is included in Appendix II of the Convention on International Trade in.

Hippopotamus. Endangered Species (CITES) meaning international export/import (including in parts and derivatives) requires CITES documentation to be obtained and presented to border authorities. As of 2017, the IUCN Red List drawn up by the International Union for Conservation of Nature (IUCN) lists the species as vulnerable, with a stable population estimated between 115,000 and 130,000 animals. Zambia (40,000) and Tanzania (20,000–30,000) possess the largest populations. The hippo population has declined most dramatically in the Democratic Republic of the Congo. By 2005, the population in Virunga National Park had dropped to 800 or 900 from around 29,000 in the mid-1970s. This decline.

Hippopotamus. is attributed to the disruptions caused by the Second Congo War. The poachers are believed to be Mai-Mai rebels, poorly paid Congolese soldiers, and local militia groups. Reasons for poaching include the belief hippos are harmful to society, as well as financial gain. As of 2016, the Virunga hippo population appears to have increased again, possibly due to greater enforcement and cooperation between fishermen and park authorities. The sale of hippo meat is illegal, but black-market sales are difficult for Virunga National Park officers to track. Hippo meat is considered a delicacy in some areas of central Africa and the.

Hippopotamus. teeth have become a valued substitute for elephant ivory.## Invasive potential.In the late 1980s, Pablo Escobar kept four hippos in a private menagerie at his residence in Hacienda Nápoles, 100 (km) east of Medellín, Colombia, after buying them in New Orleans. They were deemed too difficult to seize and move after Escobar's death in 1993, and hence were left on the untended estate. By 2007, the animals had multiplied to 16 individuals which had taken to roaming the area for food in the nearby Magdalena River. In 2009, two adults and one calf left their herd, attacking humans and killing.

Hippopotamus. cattle. One of the adults (called "Pepe") was killed by hunters under authorisation of the local authorities.When a photo of the dead hippo became public, it caused considerable controversy among animal rights groups both within the country and abroad, and plans of further culling the hippos were put on hold. Alternative methods of dealing with the hippos have been considered, but they are either unproven, too difficult, or expensive. A wild male hippo was caught, castrated, and released again, but this process cost about US$50,000. As of 2020, there were no plans by the local government for managing the population,.

Hippopotamus. but further studies of their effect on the habitat have been initiated. Because of the fast-growing population, conservationists have urged a management plan be developed quickly. Most ecologists believe the population should be eradicated, as they are breeding rapidly and are an increasing menace to humans and the environment, although some have suggested that they could represent a net positive in the ecosystem, filling the large-herbivore niche left vacant in the New World when humans arrived and wiped out almost all large species in the Pleistocene extinction.In the U.S., Representative Robert F. Broussard of Louisiana introduced the "American Hippo Bill.

Hippopotamus. in 1910 to authorise the importation and release of hippopotamus into the bayous of Louisiana. Broussard argued the hippos would eat the invasive water hyacinth that was clogging the rivers and also produce meat to help solve the American meat crisis. The chief collaborators and proponents of Broussard's bill were Major Frederick Russell Burnham and Captain Fritz Duquesne. Former President Theodore Roosevelt backed the plan, as did the U.S. Department of Agriculture, "The Washington Post", and "The New York Times", which praised hippo meat as "lake cow bacon". Although the "American Hippo Bill" developed a broad base of support, it.

Hippopotamus. was never passed by the US Congress.## Behaviour and ecology.Hippos differ from all other large land mammals in being semiaquatic, spending their days in lakes and rivers. They require habitat with enough water to submerge themselves in and which has plenty of grass nearby. When bodies of water feature firm, smooth, sloping beaches, larger numbers of hippos may congregate. Male hippos may also be found in very small numbers in rapid waters in rocky gorges. Hippos mostly live in freshwater habitats; however, populations in West Africa mostly inhabit estuarine waters and may even be found out at sea.Hippos spend most.

Hippopotamus. the day in water to stay cool and hydrated. Just before night begins, they leave the water to feed on land. Like most herbivores, hippos will consume a variety of plants if presented with them in captivity, but their diet in nature consists almost entirely of grass, with only minimal consumption of aquatic plants. A hippo will eat around 40 (kg) of grass in a night while traveling 3 – 5 (km). They typically return to the water before dawn. On occasion, hippos have been filmed eating carrion, usually near the water. There are other reports of meat-eating and even.

Hippopotamus. cannibalism and predation. The stomach anatomy of a hippo is not suited to carnivory, and meat-eating is likely caused by aberrant behaviour or nutritional stress.Because of their size and their habit of taking the same paths to feed, hippos can have a significant impact on the land across which they walk, keeping the land clear of vegetation and depressing the ground. Over prolonged periods, hippos can divert the paths of swamps and channels. By defecating in the water, the animals also appear to pass on microbes from their gut, affecting the biogeochemical cycle.## Social interaction.It is challenging to study the.

Hippopotamus. interaction of bulls and cows because hippos are not sexually dimorphic, so cows and young bulls are almost indistinguishable in the field. Although hippos lie close to one another, they are generally not social animals, and they do not seem to form social bonds except between mothers and daughters. The reason they huddle close together is unknown. Hippos exhibit territorial behaviour only in water, where the dominant bull – also known as a "beachmaster" – presides over a small stretch of river, on average 250 (m) in length. The beachmaster's territory typically contains a pod of 10 cows, but pods.

Hippopotamus. can contain over 100 hippos. Younger bachelors are allowed in a beachmaster's stretch, as long as they behave submissively toward him. Hippo territories are used to establish mating access. Within the pods, the hippos tend to segregate by sex. Bachelors lounge near other bachelors, females with other females, and the beachmaster is on his own. When hippos emerge from the water to graze, they do so individually.Hippos engage in "muck-spreading" which involves defecating while spinning their tails to distribute the faeces over a greater area. Muck-spreading occurs both on land and in water and its function is not well understood.

Hippopotamus. It is likely not territorial as the animals only establish territories in the water. "Yawning" serves as a threat display. When fighting, bulls use their incisors to block each other's attacks and their large canines to inflict injuries. When hippos become over-populated or a habitat shrinks, bulls sometimes attempt infanticide, but this behaviour is not common under normal conditions. Incidents of hippo cannibalism have been documented, but this is believed to be the behaviour of distressed or sick hippos.The most common hippo vocalisation is the "wheeze honk", which can be heard over long distances. This call starts as a high-pitched.

Hippopotamus. squeal followed by a deeper, resonant call. While the purpose of these vocalisations is unknown, they appear to be used for social cohesion, and the animals can recognise the calls of other individuals. Hippos are more likely to react aggressively to the wheeze honks of strangers than those of animals they are more familiar with. They may be able to utilise wheeze honks for echolocation. Hippos have the unique ability to hold their heads partially above the water and send out a cry that travels through both water and air; individuals respond both above and below water. They will also.

Hippopotamus. express threat and alarm with exhalations. Fighting bulls produce loud bellows.## Reproduction.Cows reach sexual maturity at five to six years of age and have a gestation period of eight months. A study of endocrine systems revealed cows may begin puberty at as early as three or four years. Males reach maturity at around 7.5 years. A study of hippo reproductive behaviour in Uganda showed that peak conceptions occurred during the end of the wet season in the summer, and peak births occurred toward the beginning of the wet season in late winter. This is because of the female's oestrous cycle;.

Hippopotamus. as with most large mammals, male hippo spermatozoa is active year-round. Studies of hippos in Zambia and South Africa also showed evidence of births occurring at the start of the wet season. After becoming pregnant, a female hippo will typically not begin ovulation again for 17 months.Mating occurs in the water, with the cow submerged for most of the encounter, her head emerging periodically to draw breath. Cows isolate themselves to give birth and return to the pod within 10 to 14 days. Calves are born underwater weighing between 25 and 50 (kg) and at an average length of around.

Hippopotamus. 127 (cm). They must swim to the surface to take their first breaths. A mother typically gives birth to only one calf, though sometimes they give birth to twins. The young often rest on their mothers' backs when the water is too deep for them, and they swim under water to suckle. They will suckle on land as well when the mother leaves the water.Mother hippos are very protective of their young and may keep others at a distance. One cow was recorded protecting a calf's carcass after it had died. Calves are occasionally left in nurseries which are guarded.

Hippopotamus. by one or a few adults. Calves in nurseries often engage in playfights. Weaning starts between six and eight months after birth, and most calves are fully weaned after a year. Like many other large mammals, hippos are described as K-strategists, in this case typically producing just one large, well-developed infant every couple of years (rather than many small, poorly developed young several times per year, as is common among small mammals such as rodents).## Interspecies interactions.Hippos coexist alongside a variety of large predators in their habitats. Nile crocodiles, lions, and spotted hyenas are known to prey on young hippos.

Hippopotamus. Beyond these, adult hippos are not usually preyed upon by other animals due to their aggression and size. Cases where large lion prides have successfully preyed on adult hippos have been reported, but it is generally rare. Lions occasionally prey on adults at Gorongosa National Park and calves are sometimes taken at Virunga. Crocodiles are frequent targets of hippo aggression, probably because they often inhabit the same riparian habitats; crocodiles may be either aggressively displaced or killed by hippos. In turn, very large Nile crocodiles have been observed preying occasionally on calves, "half-grown" hippos, and possibly also adult female hippos.

Hippopotamus. Groups of crocodiles have also been observed finishing off still-living male hippos that were previously injured in mating battles with other males.Hippos occasionally visit cleaning stations in order to be cleaned of parasites by certain species of fishes. They signal their readiness for this service by opening their mouths wide. This is an example of mutualism, in which the hippo benefits from the cleaning while the fish receive food. Hippo defecation creates allochthonous deposits of organic matter along the river beds. These deposits have an unclear ecological function. A 2015 study concluded hippo dung provides nutrients from terrestrial material for.

Hippopotamus. fish and aquatic invertebrates, while a 2018 study found that their dung can be toxic to aquatic life in large quantities, due to absorption of dissolved oxygen in water bodies.The parasitic monogenean flatworm" Oculotrema hippopotami" infests hippopotamus eyes, mainly the nictitating membrane. It is the only monogenean species (which normally live on fish) documented to live on a mammal.## Hippos and humans.The earliest evidence of human interaction with hippos comes from butchery cut marks on hippo bones found at the Bouri Formation and dated to around 160,000 years ago. Later rock paintings and engravings showing hippos being hunted have been.

Hippopotamus. found in the Tassili n'Ajjer Mountains of the central Sahara near Djanet, dated to 4,000–5,000 years ago The ancient Egyptians recognised the hippo as a ferocious denizen of the Nile and representations on the tombs of nobles show the animals were hunted by humans.The hippo was also known to the Greeks and Romans. The Greek historian Herodotus described the hippo in "The Histories" (written "" 440 BC) and the Roman naturalist Pliny the Elder wrote about the hippo in his encyclopedia "Naturalis Historia" (written "circa" 77 AD). The Yoruba people called the hippo "erinmi", which means "elephant of the water".

Hippopotamus. Some individual hippos have achieved international fame. Huberta became a celebrity during the Great Depression for trekking across a great distance in South Africa.## Attacks on humans.The hippo is considered to be extremely aggressive and has frequently been reported charging and attacking boats. Small boats can easily be capsized by hippos and passengers can be injured or killed by the animals, or drown in the water. In one 2014 case in Niger, a boat was capsized by a hippo and 13 people were killed. Hippos will often raid farm crops if the opportunity arises, and humans may come into conflict.

Hippopotamus. with them on these occasions. These encounters can be fatal to either humans or hippos.## In zoos.Hippos have long been popular zoo animals. The first record of hippos taken into captivity for display is dated to 3500 BC in Hierakonpolis, Egypt. The first zoo hippo in modern history was Obaysch, who arrived at the London Zoo on 25 May 1850, where he attracted up to 10,000 visitors a day and inspired a popular song, the "Hippopotamus Polka".Hippos generally breed well in captivity; birth rates are lower than in the wild, but this can be attributed to zoos' desire to limit.

Hippopotamus. births, since hippos are relatively expensive to maintain. The Cincinnati Zoo began building a US$73 million exhibit for three adult hippos in 2015, featuring a 250,000 (l) tank. Modern hippo enclosures also have a complex filtration system for the animal's waste, an underwater viewing platform for the visitors, and glass that may be up to 9 (cm) thick and capable of withstanding water pressures of 31 (kPa). In 1987, the Toledo Zoo saw the first underwater birth by a captive hippo. The exhibit was so popular, the logo of the Toledo Zoo was updated to feature the hippos.## Cultural significance.In.

Hippopotamus. Egyptian mythology, the god Set takes the form of a red hippopotamus and fights Horus for control of the land, but is defeated. The goddess Tawaret is depicted as a pregnant woman with a hippo head, representing fierce maternal love. The Ijaw people of the Niger Delta wore masks of aquatic animals like the hippo when practising their water spirit cults, and hippo ivory was used in the divination rituals of the Yoruba. Hippo masks were also used in Nyau rituals of the Chewa of Southern Africa. These rituals were performed at funerals. According to Robert Baden-Powell, Zulu warriors referred.

Hippopotamus. to hippos in war chants. The Behemoth from the Book of Job, 40:15–24 is thought to be based on the hippo.Hippos have been the subjects of various African folktales. According to a San story, when the Creator assigned each animal its place in nature, the hippos wanted to live in the water, but were refused out of fear they might eat all the fish. After begging and pleading, the hippos were finally allowed to live in the water on the condition they would eat grass instead of fish, and fling their dung so it can be inspected for fish bones.

Hippopotamus. In a Ndebele tale, the hippo originally had long, beautiful hair, but it was set on fire by a jealous hare and the hippo had to jump into a nearby pool. The hippo lost most of his hair and was too embarrassed to leave the water.Hippopotamuses were rarely depicted in European art during the Renaissance and Baroque periods, due to less access to specimens by Europeans. One notable exception is Peter Paul Rubens' "The Hippopotamus and Crocodile Hunt" (1615–1616). Ever since Obaysch inspired the "Hippopotamus Polka", hippos have been popular animals in Western culture for their rotund appearance, which many.

Hippopotamus. consider comical. The Disney film "Fantasia" featured a ballerina hippo dancing to the opera "La Gioconda". The film "Hugo the Hippo" involves the title character escaping Zanzibar to Dar es Salaam to avoid being slaughtered, where he is cared for by local children. The "Madagascar" films feature a hippo named Gloria. Hippos even inspired a popular board game, Hungry Hungry Hippos.Among the most famous poems about the hippo is "The Hippopotamus" by T. S. Eliot, where he compares the animal to the Catholic Church. Hippos were mentioned in the novelty Christmas song "I Want a Hippopotamus for Christmas" that became.

Hippopotamus. a hit for child star Gayla Peevey in 1953. They also feature in the popular "The Hippopotamous Song" by Flanders and Swann.A popular internet myth reports that hippos have pink milk. Biologist David Wynick states, "I think this is an Internet legend that is oft repeated but without any evidence for it that I can find... Like all mammals, hippos produce white or off-white milk for their young." Armley Hippo Owen and Mzee - hippo and tortoise who bonded.

Greenwich Hospital, London. Greenwich Hospital was a permanent home for retired sailors of the Royal Navy, which operated from 1692 to 1869. Its buildings, in Greenwich, London, were later used by the Royal Naval College, Greenwich and the University of Greenwich, and are now known as the Old Royal Naval College. The word "hospital" was used in its original sense of a place providing hospitality for those in need of it, and did not refer to medical care, although the buildings included an infirmary which, after Greenwich Hospital closed, operated as Dreadnought Seaman's Hospital until 1986.The foundation which operated the hospital still exists,.
