Saguinus Martinsi Ochraceus
The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus ''Saguinus''. They are the first offshoot in the Callitrichidae tree, and therefore are the sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets. Taxonomy and evolutionary history Hershkovitz (1977) recognised ten species in the genus ''Saguinus'', further divided into 33 morphotypes based on facial pelage. A later classification into two clades was based on variations in dental measurements. A taxonomic review (Rylands et al., 2016) showed the tamarins are a sister group to all other callitrichids, branching off 15–13 million years ago. Within this clade, six species groups are historically recognised, ''nigricollis'', ''mystax'', ''midas'', ''inustus'', ''bicolor'' and ''oedipus'', five of which were shown to be valid with ''Sanguinus inustus'' placed within the ''midas'' group. The review noted that the smaller-bodied ''nigricollis'' group began diver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emperor Tamarin
The emperor tamarin (''Saguinus imperator'') is a species of tamarin allegedly named for its resemblance to the German Empire, German List_of_German_monarchs#German_Empire,_1871–1918, emperor Wilhelm II, German Emperor, Wilhelm II. It lives in the west Brazilian States of Brazil, states of Acre State, Acre and Amazonas State, Brazil, Amazonas and the southwest Amazon Basin, in east Peru, north Bolivia. The fur of the emperor tamarin is predominantly grey colored, with yellowish speckles on its chest. The hands and feet are black and the tail is brown. Outstanding is its long, white beard, which extends to both sides beyond the shoulders. The animal reaches a length of , plus a long tail. It weighs approximately . Physical description (''Saguinus imperator imperator'') Black-chinned emperor tamarin There are claws on each of the animal's toes and fingers, aside from its big toe which has a nail. While it has a definitive long mustache, it also has almost inconspicuous white h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Édouard Louis Trouessart
Édouard Louis Trouessart (25 August 1842 – 30 June 1927) was a French zoologist born in Angers. He studied military medicine in Strasbourg, but was forced to leave school due to serious health problems. In 1864 he started work as ''préparateur de physique'' at the Faculty of Poitiers, and in the process, dedicated his time and energies to natural history. He also resumed his studies in medicine, earning a medical doctorate in 1870. During the Franco-Prussian War, he served in the French army. Later, he was employed at the hospital in Villevêque. From 1882 to 1884, he was director at the Museum of Angers, and in the meantime taught classes in natural history at the high school in Angers. In 1885 he relocated to Paris, where he worked with Alphonse Milne-Edwards (1835-1900). After the death of Emile Oustalet (1844-1905), he attained the chair of zoology (mammals and birds), a position he maintained until 1926.

Saguinus Leucopus
The white-footed tamarin (''Saguinus leucopus'') is a tamarin species endemic to Colombia. It is a silvery brown colour with pale streaks and russet underparts, and is very similar in appearance to the cotton-top tamarin, from which it is separated by the Atrato River. It is thought that the two species diverged during the Pleistocene, at a time when a sea occupied the area between their present ranges. This tamarin is an arboreal species, living in small family groups in the canopy. Females give birth to one to three young after a gestation period of about 140 days. This species has a relatively small range and is under threat from destruction and fragmentation of the forest in which it lives and the International Union for Conservation of Nature has assessed its conservation status as "vulnerable". Taxonomy and phylogeny Some authorities, such as Thorington (1976), posit that ''S. leucopus'' is very closely related to the cotton-top tamarin, ''Saguinus oedipus''. Other analys ...

Saguinus Geoffroyi
Geoffroy's tamarin (''Saguinus geoffroyi''), also known as the Panamanian, red-crested or rufous-naped tamarin, is a tamarin, a type of small monkey, found in Panama and Colombia. It is predominantly black and white, with a reddish nape. Diurnal, Geoffroy's tamarin spends most of its time in trees, but does come down to the ground occasionally. It lives in groups that most often number between three and five individuals, and generally include one or more adults of each sex. It eats a variety of foods, including insects, exudates, fruits and other plant parts. Insects and fruits account for the majority of its diet, but exudates are also important. But since its teeth are not adapted for gouging trees to get to the sap, it can only eat exudates when they are easily available. Although a variety of reproductive methods are used, the most common is for a single adult female in the group to be reproductively active and to mate with multiple adult males in the group.

Saguinus Oedipus
The cotton-top tamarin (''Saguinus oedipus'') is a small New World monkey weighing less than . This New World monkey can live up to 24 years, but most of them die by 13 years. One of the smallest primates, the cotton-top tamarin is easily recognized by the long, white sagittal crest extending from its forehead to its shoulders. The species is found in tropical forest edges and secondary forests in northwestern Colombia, where it is arboreal and diurnal. Its diet includes insects and plant exudates, and it is an important seed disperser in the tropical ecosystem. The cotton-top tamarin displays a wide variety of social behaviors. In particular, groups form a clear dominance hierarchy where only dominant pairs breed. The female normally gives birth to twins and uses pheromones to prevent other females in the group from breeding. These tamarins have been extensively studied for their high level of cooperative care, as well as altruistic and spiteful behaviors. Communication betwe ...

Saguinus Bicolor
The pied tamarin (''Saguinus bicolor''), sometimes referred to as the Brazilian bare-faced tamarin, is a Critically Endangered primate species found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of 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, it is found at the city limits of Manaus, the capital of the Amazonas state of Brazil and up to 35 km to the north and 100 km to the east. The main distribution is in the rio Cuieiras and rio Preto da Eva interfluvium. Pied tamarins are also found in the adjacent rio Preto da Eva and rio Urubu interfluvium, but are comparatively rare. There appears to be interspecific competition between the pied tamarin and the red-handed tamarin with the red-handed tamarin gradually displacing the pied tamarin from areas of its historical distribution.
