Black Tamarin
The black tamarin (''Saguinus niger'') or western black-handed tamarin is a species of tamarin endemic to Brazil. Taxonomy Based on mitochondrial DNA analysis, black tamarins were found to be more closely related to populations on the same side of the Tocantins River than on the other, showing that the river constitutes an effective gene flow barrier. As a consequence of the genetic divergence, as well as minor differences in pelage color, some recent authorities have argued for recognizing the population east of the Tocantins River as '' S. ursulus'' (eastern black-handed tamarin), leaving the "true" ''S. niger'' for the population west of this river. The closest living relative of the black tamarin is thought to be the golden-handed tamarin (''S. midas''). Description Black-handed tamarins are among the smallest primates, weighing approximately 500 grams. As with other tamarins, the hind limbs are longer than the forelimbs and the thumbs are not opposable. With the exception ...

Bagassa
''Bagassa guianensis'' is a tree in the plant family Moraceae which is native to the Guianas and Brazil. It is valued as a timber tree and as a food tree for wildlife. The juvenile leaves are distinctly different in appearance from the mature leaves, and were once thought to belong to different species. Description ''Bagassa guianensis'' is a large, latex-producing, dioecious, deciduous tree which reaches heights of up and a diameter at breast height of . The leaves are deeply three-lobed in juveniles, but become entire as the tree matures. They are usually long, sometimes up to long, and wide (sometimes up to wide). Male and female flowers are borne on separate inflorescences. Male inflorescences are arranged in a spike, which is long. Female inflorescences are arranged into a compact head which is in diameter. The infructescences are in diameter. Taxonomy ''Bagassa'' is a monotypic genus—it includes only one species, ''B. guianensis''. The genus was establis ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

Polygynandry
Polygynandry is a mating system in which both males and females have multiple mating partners during a breeding season. In sexually reproducing diploid animals, different mating strategies are employed by males and females, because the cost of gamete production is lower for males than it is for females. The different mating tactics employed by males and females are thought to be the outcome of stochastic reproductive conflicts both ecologically and socially. Reproductive conflicts in animal societies may arise because individuals are not genetically identical and have different optimal strategies for maximizing their fitness; and often it is found that reproductive conflicts generally arise due to dominance hierarchy in which all or a major part of reproduction is monopolized by only one individual. In the wasp '' Polistes carolina'', the dominant queen amongst female wasps is determined by whoever arrives at the nest first rather than the largest foundress, who is expected to be ...

Polyandry In Nature
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 ...

Polygyny In Animals
Polygyny (; from Neo-Greek , ) is a mating system in which one male lives and mates with multiple females but each female only mates with a single male. Systems where several females mate with several males are defined either as promiscuity or polygynandry. Lek mating is frequently regarded as a form of polygyny, because one male mates with many females, but lek-based mating systems differ in that the male has no attachment to the females with whom he mates, and that mating females lack attachment to one another.Clutton-Brock T.H. (1989). ‘Review lecture: mammalian mating systems.' ''Proceedings of the Royal Society of London''. Series B, Biological Sciences 236: 339–372. Polygyny is typical of one-male, multi-female groupsBoyd, R., & Silk, J. B. (2009).

Monogamy In Animals
Some animal species have a monogamous mating system, in which pairs bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J. (2008)Social but not genetic monogamy is associated with greater breeding success in prairie voles/ref> As an example, in the cichlid species '' Variabilichromis moorii'', a monogamous pair will care for eggs and y ...

Goeldi's Marmoset
Goeldi's marmoset, or Goeldi's monkey (''Callimico goeldii''), is a small New World monkey found on the South American continent, mainly in the upper Amazon basin of Bolivia, Brazil, Colombia, and Perú. It is the only species classified in the monotypic genus ''Callimico'', thus these monkeys are sometimes referred to as "callimicos". The species takes its name from its discoverer, Swiss-Brazilian naturalist Emil August Goeldi. Likely an evolutionary adaptation for camouflage and the evasion of predators, Goeldi's marmosets are a dark-furred species, usually a blackish-gray or darker brown in color. Superficially, the short hair on their head gives them a vague resemblance to the larger woolly monkey ('' Lagothrix''); however, the back of their necks, their backside, and tails often display light, horizontal striping or highlights. Their bodies are about long, and their tails are about another long. Captive Goeldi's marmosets weigh around , while observed individuals were appr ...

Ocelot
The ocelot (''Leopardus pardalis'') is a medium-sized spotted Felidae, wild cat that reaches at the shoulders and weighs between on average. It is native to the southwestern United States, Mexico, Central America, Central and South America, and the Caribbean islands of Trinidad and Margarita Island, Margarita. Carl Linnaeus scientific description, scientifically described it in 1758. Two subspecies are recognized. The ocelot is efficient at climbing, leaping and swimming. It prefers areas close to water sources with dense vegetation cover and high prey availability. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. It is typically active during twilight and at night and tends to be solitary and Territory (animal), territorial. Both sexes become sexual maturity, sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically.

Margay
The margay (''Leopardus wiedii'') is a small wild cat native to Mexico, Central and South America. A solitary and nocturnal felid, it lives mainly in primary evergreen and deciduous forest. Until the 1990s, margays were hunted for the wildlife trade, at which point the killing of the species was outlawed in most countries; however, years of persecution resulted in a notable population decrease. Since 2008, the margay has been listed as Near Threatened on the IUCN Red List, as the population is thought to be declining due to loss of habitat and deforestation. The scientific name ''Felis wiedii'' was used by Heinrich Rudolf Schinz in 1821 in his first scientific description of the margay, named in honour of Prince Maximilian of Wied-Neuwied, who collected specimens in Brazil. Characteristics The margay is very similar to the larger ocelot (''Leopardus pardalis'') in appearance, although the head is a little shorter, the eyes larger, and the tail and legs longer. It weighs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
