Top predators like the Neotropical otter, Lontra longicaudis annectens, are usually considered good bioindicators of habitat quality. The Neotropical otter Lontra longicaudis is a widespread semiaquatic carnivore living in a wide variety of environments in both fresh-water and salt-water ecosystems. Neotropical River Otters are members of the family Mustelidae, which includes weasels, badgers, grison, tayra and wolverine. The left picture is a habitat of a Neotropical Otter in the Peru region and on the right is a habitat in Chihuahua, Mexico. We compared giant otter feeding habits between seasons and habitats in the Southern Pantanal, Brazil, by analyzing feces … They depend on a water environment with plenty of riparian vegetation (Nowak 1999). In this study, we evaluated heavy metal contamination (Hg tot, Pb, Cd) in the riverine habitat, prey (crustaceans and fish), and otter feces in … They are the least aquatic of all otters. Southern river otters are found in Argentina and Chile. These versatile otters are found in a very wide variety of environments. The Neotropical otter (Lontra longicaudis) is listed as Near Threatened by the IUCN, which describes the standardization of field survey techniques and identification of key habitats as two research priorities. These otters only breed once a year and the male otters stay with the female for only one day. Habitat and Home of the Neotropical Otter . Giant otters Pteronura brasiliensis are semiaquatic mammals that mainly eat fish, the abundance of which is affected by seasonal flooding and habitat structure. - "NEOTROPICAL RIVER OTTER MICRO-HABITAT PREFERENCE IN WEST-CENTRAL CHIHUAHUA, MEXICO" A large otter with a very, very long tail (hence the latin name), the Neotropical River otter seems to have a large distribution but an unknown population size.

This is mostly from Waldemarin (2004) and Gallo-Reynoso (2002).. Habitat Degradation and Destruction. Cape clawless otters inhabit the southern two-thirds of the African continent. Feeding Habits The Neotropical Otter does 20 to 30 second dives as it forages for prey (Lariviere, 1999). Both figures express the wide distribution and variability of sites used by the Neotropical otter, considering the habitat structural features. native; Habitat. neotropical. 6, Issue. Neotropical otter. Wild population numbers of both species are merely speculation, due to insufficient data collection and it is therefore vital to develop more otter workers to deliver the data. Neotropical River Otters, also known as the Amazonian river otter or the water dog, have been kept in captivity by fishermen so that they can be trained to catch fish for the men. It devours smaller prey while it is still in the water but will drag larger prey to the shore (Lariviere, 1999). Its current category in the International Union for Conservation of Nature is “data deficient,” which makes it imperative to determine the appropriate conservation status. The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries. Group Bull.18 (2) 2001 IUCN OTTER SPECIALIST GROUP BULLETIN VOLUME 18 ISSUE 2 PAGES 86 - 92 Citation: González, I. Over the years, humans hunted otters for their fur, meat and destruction of their habitats such as pollution of rivers and deforestation for 1, p. 62. Abstract Top predators like the Neotropical otter, Lontra longicaudis annectens, are usually considered good bioindicators of habitat quality. The neotropical otter, Lontra longicaudis, is widely distributed in the Americas, but populations are being decimated by hunting, habitat loss, water pollution, and roadkills. The Neotropical otter is the greatest generalist of all otter species, inhabiting a range of habitats including wastewater treatment plants, rice and sugar cane plantations, drainage ditches and swamps to cold, glacial lakes in the Andes of Ecuador. Neotropical river otters spend most of their time playing and swimming in waters and are easily captured and eaten by caimans. Top predators like the Neotropical otter, Lontra longicaudis annectens, are usually considered good bioindicators of habitat quality. 21(2): 86 - 92 DISTRIBUTION OF THE NEOTROPICAL OTTER Lontra longicaudis IN THE VENEZUELAN … Also, when forests are cleared for cattle grazing, heavy vegetation (which is the otter’s preferred habitat) near streams is also cleared or trampled by cattle. We characterised habitat selected by the Neotropical otter (Lontra longicaudis) in the Rio San Pedro, located in the central portion of the State of Chihuahua in Northern Mexico. Giant otters are found throughout almost all of South America. Otters showed a preference (97% C.I.) Neotropical otters are threatened by habitat degradation associated with: agriculture, soil compaction, pollution, roadways, and runoff. The Neotropical otter and the giant otter present different patterns of habitat use, when compared through habitat features (Fig. Neotropical Biodiversity, Vol. Neotropical River Otters are semiaquatic and typically solitary, and can be found in a wide variety of riverine habitats, preferably with clear, fast-flowing water within forests, savannahs, llanos and Pantanal. Top predators like the Neotropical otter, Lontra longicaudis annectens, are usually considered good bioindicators of habitat quality. The Neotropical Otter lives in a variety of habitats but little is known of its ecology, distribution or population status in Guyana. Basic ecological information such as habitat selection and diet is also lacking, especially in Central America. Otters can be tolerant to human presence, structural habitat degradation, and even to a certain degree of water pollution, at least in the short term. We monitored a 30 km stretch of the river for over two years and compared micro-site habitat characteristics at 21 used and 25 random sites. Pool category C, however, was used in proportion to its availability, whilst categories D and E were avoided. In this study, we evaluated heavy metal contamination (Hg(tot), Pb, Cd) in the riverine habitat, prey (crustaceans and fish), and otter feces in two Ramsar wetlands with contrasting upstream contamination discharges: Río Blanco and Río Caño Grande in … Slash and burn clearing for crops and cattle rearing, and large scale logging, always to produce maximum yield in minimum time, destroys jungles, woods and riverside vegetation.

Neotropical otters are threatened by habitat degradation associated with: agriculture, soil compaction, pollution, roadways, and runoff. ... Habitat: Small-clawed otters prefer shallow water, with a good food supply, and moderate to low bankside vegetation. As members of the Mustelidae family, otters are related to weasels, badgers, wolverines, minks and tayras.Otters are semi-aquatic or aquatic carnivorous mammals, found in both marine and freshwater habitats in Europe, North America, and Central and South America. 1,2). IUCN Otter Spec. An otter population was located in southern Tehuacán-Cuicatlán Biosphere Reserve (TCBR), Mexico. Abstract. The Neotropical river otter Lontra longicaudis is a top predator in many South and Central American aquatic freshwater systems. The Neotropical otter (Lontra longicaudis) is listed as Near Threatened by the IUCN, which describes the standardization of field survey techniques and identification of key habitats as two research priorities. Africa. It is a versatile otter that is found in many habitats – one sighting in Chile was made at 3885 m above sea level! Kruuk (2006) also found that hunting can be an important threat locally. The recent increase in available information on the Neotropical Otter reveals this species to be Near Threatened in large portions of its range. Habitat selection and diet of the Neotropical otter (Lontra longicaudis) on the Osa Peninsula, Costa Rica, and range-wide monitoring recommendations. The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries. The lesson called Neotropical Otter: Habitat & Facts will teach you more about the following bullet points: Various names for the neotropical otter The type of climate where these animals can live Key Information: This is the smallest of the world’s otters, about 0.9 m long, weighing around 5 kg.
