Peruvian Spider Monkey
The Peruvian spider monkey (''Ateles chamek''), also known as the black-faced black spider monkey, is a species of spider monkey that lives in Peru, as well as in Brazil and in Bolivia. At long, they are relatively large among species of monkey, and their strong, prehensile tails can be up to long. Unlike many species of monkey, they have only a vestigial thumb, an adaptation which enables them to travel using brachiation. Peruvian spider monkeys live in groups of 20–30 individuals, but these groups are rarely all together simultaneously. The size and dynamics of the resulting subgroups vary with food availability and sociobehavioral activity. They prefer to eat fleshy fruit, but will change their diet in response to scarcity of ripe fruit. Individuals of this species also eat small animals, insects and leaves based on availability. Females separate from the band to give birth, typically in the fall. These females inhabit a group of core areas where resources are abundant in ce ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 1769 – 6 May 1859) was a German polymath, geographer, natural history, naturalist, List of explorers, explorer, and proponent of Romanticism, Romantic philosophy and Romanticism in science, science. He was the younger brother of the Prussian minister, philosopher, and linguistics, linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botany, botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern Earth's magnetic field, geomagnetic and meteorology, meteorological monitoring. Humboldt and Carl Ritter are both regarded as the founders of modern geography as they established it as an independent scientific discipline. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a non-Spanish European scientific point of view. His des ...

CITES
CITES (shorter acronym for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 40,900 species. , the Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three workin ...

Mammals Of Peru
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Primates Of Brazil
Primates is an order (biology), order of mammals, which is further divided into the Strepsirrhini, strepsirrhines, which include lemurs, galagos, and Lorisidae, lorisids; and the Haplorhini, haplorhines, which include Tarsiiformes, tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial animal, terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among Canopy (biology), tree tops, including large brain sizes, binocular vision, color vision, Animal communication, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (in most but not all) that enable better grasping and dexterity. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is ...

Spider Monkeys
Spider monkeys are New World monkeys belonging to the genus ''Ateles'', part of the subfamily Atelinae, family Atelidae. Like other atelines, they are found in tropical forests of Central and South America, from southern Mexico to Brazil. The genus consists of seven species, all of which are under threat; the brown spider monkey is critically endangered. They are also notable for their ability to be easily bred in captivity. Disproportionately long limbs and long prehensile tails make them one of the largest New World monkeys and give rise to their common name. Spider monkeys live in the upper layers of the rainforest and forage in the high canopy, from . They primarily eat fruits, but will also occasionally consume leaves, flowers, and insects. Due to their large size, spider monkeys require large tracts of moist evergreen forests, and prefer undisturbed primary rainforest. They are social animals and live in bands of up to 35 individuals, but will split up to forage during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ateles Belzebuth
The white-bellied spider monkey (''Ateles belzebuth''), also known as the white-fronted or long-haired spider monkey, is an endangered species of spider monkey, a type of New World monkey. It is found in the north-western Amazon in Colombia, Ecuador, Venezuela, Peru and Brazil, ranging as far south as the lower Ucayali River and as far east as the Branco River. In the past, the Peruvian, brown and white-cheeked spider monkeys have been treated as subspecies of ''A. belzebuth''. As presently defined, the white-bellied spider monkey is monotypic. It has a whitish belly and a pale patch on the forehead, which, despite its common name, often is orange- buff, though this might be due to dirt and other stainers. They live in groups of 20 to 40 individuals, splitting into small parties of 1 to 9 when in activity. Vernacular names include ''mono prieto'', ''mico prieto'' and ''marimonda'' (Colombia). Over the last 45 years (3 generations), the population has declined by approximately 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Spider Monkey
The brown spider monkey or variegated spider monkey (''Ateles hybridus'') is a critically endangered species of spider monkey, a type of New World monkey, from forests in northern Colombia and northwestern Venezuela. Like all spider monkeys, it has long, slender limbs and a long prehensile tail. The brown spider monkey has a whitish belly and patch on the forehead, and – highly unusual among spider monkeys – its eyes can be pale blue. Taxonomy Some scientists recognize two subspecies, ''Ateles hybridus hybridus'', found in both Colombia and Venezuela and ''Ateles hybridus brunneus'', found between Cauca River, Cauca and Magdalena River in Colombia. Molecular studies have not supported the subspecies designations and treat the species as a single taxon. Physical description The brown spider monkey has long and thin limbs with longer forelimbs than hind limbs. It has a distinctive long flexible, thin and prehensile tail which at times acts like a fifth limb. The tail has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoffroy's Spider Monkey
Geoffroy's spider monkey (''Ateles geoffroyi''), also known as the black-handed spider monkey or the Central American spider monkey, is a species of spider monkey, a type of New World monkey, from Central America, parts of Mexico and possibly a small portion of Colombia. There are at least five subspecies. Some primatologists classify the black-headed spider monkey (''A. fusciceps''), found in Panama, Colombia, and Ecuador as the same species as Geoffroy's spider monkey. It is one of the largest New World monkeys, often weighing as much as . Its arms are significantly longer than its legs, and its prehensile tail can support the entire weight of the monkey and is used as an extra limb. Its hands have only a vestigial thumb, but long, strong, hook-like fingers. These adaptations allow the monkey to move by swinging by its arms beneath the tree branches. Geoffroy's spider monkey lives in fission–fusion societies that contain between 20 and 42 members. Its diet consists pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here ''sets of chromosomes'' refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes naturally exist. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more sets of chromosomes. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an o ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Red-faced Spider Monkey
The red-faced spider monkey (''Ateles paniscus''), also known as the Guiana spider monkey or red-faced black spider monkey, is a species of spider monkey found in the rain forests in northern South America. The species faces issues with hunting and habitat destruction, habitat loss, so is listed as Vulnerable species, Vulnerable on the IUCN Redlist. Description The red-faced spider monkey has long, black hair and a red or pink face that is bare except for a few short, white hairs. Infants are born with dark faces, which lighten as they age. Sexual dimorphism in the species is small; the head-body length of the male is on average, while the female is around in length. The male weighs around , while the female weighs around . The tail is prehensile (capable of grasping) and its fingers and limbs are long, agile and strong. Behavior The red-faced spider monkey exhibits a fission-fusion society, associating with large groups of up to 30 individuals during the night, but cho ...
