Northern Muriqui
The northern muriqui (''Brachyteles hypoxanthus)'' is one of two species of muriqui. They are also known as woolly spider monkey because they exhibit the woollen pelt of woolly monkeys and the long prehensile tail of spider monkeys. Muriquis are the largest extant New World monkeys. They can reach long and weight up to . The northern muriqui is a critically endangered species, it is estimated that there are less than 1,000 mature individuals in the wild. The species is unusual among primates in that males and females are about the same size. Males are no bigger or stronger than females, a factor believed to influence their egalitarian tendencies in social relationships. This species is endemic to the Atlantic Forest region of Brazilian states of Rio de Janeiro, Espírito Santo, Minas Gerais and Bahia. Their diets, travel patterns and reproductive cycles are seasonally determined. The size of each group can fluctuate as females move between groups of monkeys. Morphology and id ...

Heinrich Kuhl
Heinrich Kuhl (17 September 1797 – 14 September 1821) was a German people, German naturalist and zoologist. Kuhl was born in Hanau (Hesse, Germany). Between 1817 and 1820, he was the assistant of professor Th. van Swinderen, docent of natural history at the University of Groningen in Groningen (the Netherlands). In 1817, he published a monograph on bats, and in 1819, he published a survey of the parrots, ''Conspectus psittacorum''. He also published the first monograph on the petrels, and a list of all the birds illustrated in Edme-Louis Daubenton, Daubenton's ''Planches Enluminées'' and with his friend Johan Coenraad van Hasselt (1797–1823) ''Beiträge zur Zoologie und vergleichenden Anatomie'' ("Contributions to Zoology and Comparative Anatomy") that were published at Frankfurt-am-Main, 1820. In 1820, he became assistant to Coenraad Jacob Temminck at the Leiden Rijksmuseum van Natuurlijke Historie. He then travelled to Java (island), Java, then part of the colonial Nethe ...

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psychotria
''Psychotria'' is a large genus of flowering plants in the coffee family Rubiaceae, with over 1,600 species. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests.

Palicourea
''Palicourea'' is a genus of flowering plants in the family (biology), family Rubiaceae. It contains 694 species, which range from shrubs to small trees, and is distributed throughout the New World tropics.Taylor (2008) These plants are closely related to ''Psychotria'' and in particular its subgenus ''Heteropsychotria''. Indeed, it seems to be nothing else but a distinctively-flowered offshoot of ''Heteropsychotria''; arguably, it would thus need to be merged into ''Psychotria'' to make that genus monophyletic. On the other hand, ''Psychotria'' is extremely diverse already, so it is probably more practical to move the more distantly related species out of this genus and merge ''Heteropsychotria'' with ''Palicourea''. By a Hungarian botanist Attila Borhidi, some of the ''Psychotria'' species have been transferred into this genus. The genus is not well studied. Most species are Distyly, distylous, although a few on isolated Caribbean islands seem to have lost the trait. Flowers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andira
''Andira'' is a genus of flowering plants in the legume family, Fabaceae. It is distributed in the tropical Americas, except for ''A. inermis'', which also occurs in Africa. It was formerly assigned to the tribe Dalbergieae, but molecular phylogenetic studies in 2012 and 2013 placed it in a unique clade within subfamily Faboideae named the ''Andira'' clade. Compared to other Faboideae the genus has unusual systems of root nodules and fruits, which are drupes. In most species the fruits are dispersed by bats, and in some they are dispersed by rodents. They may also be dispersed on water. Plants of the genus are used in traditional medicine in Brazil to treat fever and as purgatives and vermifuges. The treatments are toxic in high doses, however. Chemical compounds isolated from the genus include isoflavones, flavanols, glycosides, pterocarpans, chromone, and ursolic acid.

Margaritaria Nobilis
Margaritaria nobilis, also known as the bastard hogberry, is a fruit-bearing plant in the family Phyllanthaceae. It is native to Mexico, Central America, South America, and the West Indies. Description ''Margaritaria nobilis'' is a medium-sized tree that can grow up to 20 meters tall. The leaves are alternate, simple, and entire, typically ovate to elliptic in shape. Its small greenish flowers are unisexual and are typically clustered in axillary inflorescences. The fruit is a capsule that splits open to reveal bright iridescent blue seeds. The striking blue color is not due to pigmentation but results from structural coloration caused by the unique arrangement of cellulose microfibrils that interfere with light waves, producing a metallic sheen. Distribution and Habitat ''Margaritaria nobilis'' is distributed across tropical and subtropical regions of the Americas. It occurs from southern Mexico through Central America (including Belize, Guatemala, and Honduras) down to Brazil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
