Pied Tamarin
The pied tamarin (''Saguinus bicolor''), sometimes referred to as the Brazilian bare-faced tamarin, is a critically endangered species of primate found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Manaus, Brazil in 2005. The species is endangered due to the increasing size of the city of Manaus, which is encroaching on their native habitat. Distribution and habitat A New World monkey, the pied tamarin is found at the city limits of Manaus, the capital city, capital of the Amazonas (Brazilian state), Amazonas state of Brazil and up to to the north and to the east. A tamarin group has a home range of . The main distribution is in the interfluvial areas of the Cuieiras River (Rio Negro), Rio Cuieiras and Preto da Eva River, Rio Preto da Eva. Pied tamarins are also found in the adjacent interfluvial areas of the Rio Preto da Eva and Urubu River (Amazonas), Rio Urubu, but are comparatively rare. The pied tamarin is found in Primary for ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Feral
A feral (; ) animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded ...

The World's 25 Most Endangered Primates
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress ...

Golden-handed Tamarin
The golden-handed tamarin (''Saguinus midas''), also known as the red-handed tamarin or Midas tamarin, is a New World monkey belonging to the family Callitrichidae. Distribution and habitat This species is native to wooded areas north of the Amazon River in Brazil, Guyana, French Guiana, Suriname, and possibly Venezuela. A population of tamarins south of the Amazon River that lack the contrasting feet and hands was previously believed to be a sub-population of golden-handed tamarins but is now treated as a separate species, the black tamarin. Populations of golden-handed tamarins appear to be expanding into the historical range of the pied tamarin, with the golden-handed tamarin gradually displacing the pied tamarin through interspecific competition. This species prefers trees with small crowns. Description The golden-handed tamarin's body measures ; including the tail it measures . It weighs . The fur of the golden-handed tamarin is dark brown or black, with contrasting gol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Alloparenting
Alloparenting (or alloparental care) is a term for any form of parental care provided by an individual towards young that are not its own direct offspring. These are often called "non-descendant" young, even though grandchildren can be among them. Among humans, alloparenting is often performed by a child's grandparents and older siblings. Individuals providing this care are called by the neutral term "alloparent" (or "helper"). Alloparental care encapsulates a diverse range of parenting systems across a range of animal groups and social structures. The alloparent–young relationship can be mutualistic or parasitic, and between or within species. Cooperative breeding, joint brood care, reciprocal allonursing, brood parasitism and cuckoldry represent situations in which alloparenting plays a role. This form of parenting is often seen among humans. However, it is not as popular among other species. Alloparenting is rare among classes of animals such as birds and mammals, with only ...

Polyandry In Animals
In behavioral ecology, polyandry is a class of mating system where one female mates with several males in a breeding season. Polyandry is often compared to the polygyny system based on the cost and benefits incurred by members of each sex. Polygyny in nature, Polygyny is where one male mates with several females in a breeding season (e.g., lions, deer, some primates, and many systems where there is an Alpha (biology), alpha male). A common example of polyandrous mating can be found in the field cricket (''Gryllus bimaculatus'') of the insect order Orthoptera (containing crickets, grasshoppers, and groundhoppers). Polyandrous behavior is also prominent in many other insect species, including honeybees, the red flour beetle, the Callosobruchus chinensis, adzuki bean weevil, and the species of spider ''Stegodyphus lineatus''. Polyandry also occurs in some mammals including primates such as marmosets and the marsupial genera ''Antechinus'' and bandicoots, and in around 1% of all bird ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek language, Greek () and (). Pheromones are also sometimes classified as ec ...

Multi-male Group
Basic requirements of individual primates include obtaining food, avoiding predators, and reproducing. When these basic requirements are best pursued in the company of others, groups will form. Multi-male groups, also known as multi-male/multi-female, are a type of social organization where the group contains more than one adult male, more than one adult female, and offspring. This structure is characterized by group living (as opposed to solitary), polygynandrous, and strong reproductive competition among males, which could result in an uneven division of male reproductive success (i.e. reproductive skew). There are no stable heterosexual bonds as both males and females have a number of different mates. Multi-male groups are common among semi-terrestrial primates, like savanna baboons, macques, colobus and some New World monkeys. Avoiding predators A factor influencing the number of males in a group may be to avoid predators, as a study found significant positive correlations be ...

Reserva Florestal Adolpho Ducke
The Adolfo Ducke Forest Reserve () is a protected area of the Amazon rainforest on the outskirts of the city of Manaus, Brazil. The reserve was established in 1963 in honour of the entomologist and botanist Adolfo Ducke (1876–1959), who was one of the most respected experts on Amazonian flora. It is part of the Long Term Ecological Research Network (LTER). The reserve sits at the intersection of two major drainage areas, the Amazon River and the Rio Negro. The reserve is made up of research plots designed to study the biota of the regions, which serve as a basis for biodiversity surveys in other areas of the Amazon region, and studies on the impacts of fragmentation. The grid of LTER sites is made up of plots inserted into a larger grid of plots. Within the grid, which is used for straight line transect surveys of biodiversity, there are long permanent survey plots. The Adolfo Ducke Forest Reserve is one of the most intensively studied patches of rainforest in the world. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
