Black Bearded Saki
The black bearded saki (''Chiropotes satanas'') is a species of New World monkey, native to the Amazon rainforest of South America, specifically to an area of north-eastern Brazil. It is one of five species of bearded saki. Bearded sakis are medium-sized (50 cm), mostly frugivorous primates, specialised in seed predation. The genus name ''Chiropotes'' means "hand-drinker" as they have been observed using their hands as ladles for scooping water into their mouths. This behavior is thought to be a way of maintaining and protecting their characteristic beards. The black bearded sakis habitat has undergone heavy habitat fragmentation, making the future conservation status of the species uncertain. Distribution and habitat Black bearded sakis are endemic to the far eastern Amazon in Brazil, in a range restricted to a relatively small region from the Tocantins River in Pará east to around the Grajaú River in Maranhão (similar to the range of the equally threatened Kaapori cap ...

Johann Centurius Hoffmannsegg
Johann Centurius Hoffmann Graf von Hoffmannsegg (23 August 1766 – 13 December 1849) was a German botanist, entomologist and ornithologist. Hoffmannsegg was born at Rammenau and studied at Leipzig and Göttingen. He travelled through Europe acquiring vast collections of plants and animals. He visited Hungary, Austria and Italy in 1795–1796 and Portugal from 1797 to 1801. He sent his collections to Johann Karl Wilhelm Illiger, then in Brunswick, so that he could study them. Hoffmannsegg worked in Berlin from 1804 to 1816, and was elected a member of the Academy of Science of the city in 1815. He was the founder of the zoological museum of Berlin in 1809. Hoffmannsegg proposed Illiger for the position of curator, and all the Hoffmannsegg's collections were then transferred to Berlin. The legume genus ''Hoffmannseggia ''Hoffmannseggia'' is a genus of flowering plants in the pea family, Fabaceae, known generally as rushpeas. These are pod-bearing herbs and subshrub ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysobalanaceae
Chrysobalanaceae is a family of flowering plants, consisting of trees and shrubs in 27 genera and about 700 species of pantropical distribution with a centre of diversity in the Amazon. Some of the species contain silica in their bodies for rigidity and so the mesophyll often has sclerenchymatous idioblasts. The widespread species ''Chrysobalanus icaco'' produces a plum-like fruit and the plant is commonly known as the coco plum. The family was traditionally placed as subfamily Chrysobalanoideae in the rose family ( Rosaceae) or as a family in the rose order and exceptionally as an order in Myrtiflorae by Dahlgren In the phenotypic cladistic analysis of Nandi et al., it branched with Elaeagnaceae as sister group of Polygalaceae, in their molecular cladistic analysis it was in Malpighiales The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than species, about 7.8% of the eudicots. The order is very diverse, contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecythidaceae
The Lecythidaceae comprise a family (biology), family of about 20 genera and 250–300 species of woody plants native to tropical South America, Africa (including Madagascar), Asia and Australia. The most important member of the family in world trade is the Brazil nut (''Bertholletia excelsa''), valued for its edible nut (fruit), nuts; the paradise nut (''Lecythis'' species) is also eaten. Taxonomy According to the most recent molecular analysis of Lecythidaceae by Mori ''et al.'' (2007), the three subfamilies are: *Foetidioideae (Foetidiaceae) from Madagascar include only ''Foetidia''. *Planchonioideae (including Barringtonia) are restricted to the Old World tropics. *Lecythidoideae (Lecythidaceae) are restricted to the New World tropics. Two other families are sometimes included in Lecythidaceae; the Scytopetalaceae and Napoleonaeaceae are hypothesized as most closely related to Lecythidaceae. The APG II system of 2003 includes genera from the family Scytopetalaceae in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sapotaceae
240px, '' Madhuca longifolia'' var. ''latifolia'' in Narsapur, Medak district, India The Sapotaceae are a family (biology), family of flowering plants belonging to the order (biology), order Ericales. The family includes about 800 species of evergreen trees and shrubs in around 65 genera (35-75, depending on generic definition). Their distribution is pantropical. Many species produce edible fruits, or white blood-sap that is used to cleanse dirt, organically and manually, while others have other economic uses. Species noted for their edible fruits include ''Manilkara'' (sapodilla), ''Chrysophyllum cainito'' (star-apple or golden leaf tree), and ''Pouteria'' ('' abiu, canistel, lúcuma'', mamey sapote). ''Vitellaria paradoxa'' (''shi'' in several languages of West Africa and ''karité'' in French; also anglicized as shea) is also the source of an oil-rich nut, the source of edible shea butter, which is the major lipid source for many African ethnic groups and is also used in t ...

Seed Predation
Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source,Hulme, P.E. and Benkman, C.W. (2002) "Granivory", pp. 132–154 in ''Plant animal Interactions: An Evolutionary Approach'', ed. C.M. Herrera and O. Pellmyr. Oxford: Blackwell. . in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates (especially mammals and birds) as well as invertebrates (mainly insects); thus, seed predation occurs in virtually all terrestrial ecosystems. Seed predation is commonly divided into two distinctive temporal categories, pre-dispersal and post-dispersal predation, which affect the fitness of the parental plant and the dispersed offspring (the seed), respectively. Mitigating pre- and post-dispersal predation may involve different strategies. To counter seed predation, plants have evolved both physical defenses ( ...

Chiropotes Skull Front View 2
The bearded sakis, or cuxiús are five or six species of New World monkeys, classified in the genus ''Chiropotes''. They live in the eastern and central Amazon in South America, ranging through southern Venezuela, Guyana, Suriname, French Guiana and northern and central Brazil. The species are entirely allopatric, their distributions being separated by major rivers. Bearded sakis differ from the closely related saki monkeys of the genus '' Pithecia'' by a pronounced beard, a tuft of hair that extends from its jaw, down its throat to the top of its chest, and is strongly pronounced particularly in the males. The tail is long and hairy, and is used for balance and not grasping. Bearded sakis reach from 32 to 51 cm in size and a weigh from 2 to 4 kg. Like many New World monkeys, bearded sakis are diurnal and arboreal. They inhabit tropical rainforests, usually in the crowns of tree. They move on all four by the branches, spending most of the day searching for food. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (molecule), water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown-backed Bearded Saki
The brown-backed bearded saki (''Chiropotes israelita'') is one of five species of bearded saki, a type of New World monkey. It is endemic to the Amazon in north-western Brazil (north of the Rio Negro and west of the Branco River) and southern Venezuela.Bonvicino, C. R., Boubli, J. P., Otazú, I. B., Almeida, F.
