Barbara Brown's Titi
Barbara Brown's titi monkey (''Callicebus barbarabrownae''), also popularly known as the blond titi monkey or northern Bahian blond titi, is a species of titi, a type of New World monkey. This critically endangered species is endemic to the Caatinga in northeastern Brazil, and it is estimated that less than 250 mature individuals remain. It is named after the zoologist Barbara Elaine Russell Brown. Home range The blonde titi monkey is listed as Critically Endangered due to small population size. The blond titi monkey is endemic to the Atlantic forests of eastern Brazil, where it is found in the coastal highlands of Bahia and Sergipe States. Most of their population is found between the Paraguaçu River (north) and Salvador (south), and west towards Mirorós. The estimated population is 260 individuals and is decreasing. ''C. barbarabrownae'' has been listed among the World's 25 Most Endangered Primates in 2012. Habitat and ecology The blond titi prefers habitats in caatinga a ...

Barbara Elaine Russell Brown
Barbara Elaine Russell Brown (February 14, 1929 - January 7, 2019) was an American biologist and philanthropist. Personal life Brown was born Barbara Russell, on 14 February 1929 in Chicago; her parents were Jewish immigrants from Romania and Russia. She graduated from the University of Illinois with a bachelor's degree in economics. In 1953, she married Roger Brown; they went on to have six children together. She moved to Highland Park, IL shortly after marrying, where the couple purchased five acres of undeveloped orchard, woodland, and marsh within the suburb, later adding five more acres to accommodate their children and dogs. Barbara enriched her community by joining the Highland Park Library Board, serving the city's Environmental Commission, as a guide at the Heller Nature Center, and by volunteering at elementary schools and extracurriculars. For decades, she was the president of the North Shore Bird Club, and was an avid birder through the United States, Canada, Austral ...

Philip Hershkovitz
Philip Hershkovitz (12 October 1909 – 15 February 1997) was an American mammalogy, mammalogist. Born in Pittsburgh, he attended the Universities of Pittsburgh and Michigan and lived in South America collecting mammals. In 1947, he was appointed a curator at the Field Museum of Natural History in Chicago and he continued to work there until his death. He published much on the mammals of the Neotropics, particularly primates and rodents, and described almost 70 new species and subspecies of mammals. About a dozen species have been named after him. Life Early life Philip Hershkovitz was born on 12 October 1909 in Pittsburgh to parents Aba and Bertha (Halpern) Hershkovitz. He was the second child and only son among four siblings. He reported that his father died when he was nine years old. After graduating from Schenley High School in 1927, he attended the University of Pittsburgh from 1929 to 1931, majoring in zoology, before transferring to the University of Michigan at Ann Arbo ...

Caatinga
Caatinga () is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" comes from the Tupi word '' ka'atinga'', meaning "white forest" or "white vegetation" ('' ka'a'' = forest, vegetation, '' tinga'' = white). The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month-long rainy season. Caatinga falls entirely within earth's tropical zone and is one of six major biomes of Brazil. It covers 912,529 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals. The Caatinga is the only exclusively Brazilian biome, which means that a large part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Mammals Of Brazil
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

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 ...

Callicebus
''Callicebus'' is a genus of monkeys known as titi monkeys. Historically, titis were monogeneric, comprising only the genus ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae; ''Cheracebus'' Byrne et al., 2016 for the species of the ''torquatus'' group (Widow titis); ''Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; and ''Callicebus'' Thomas, 1903 ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group. In 2014, a previously unknown orange ''Callicebus'' was spotted in the Peruvian Amazon; it has not been determined whether this constitutes a color variant or a new species. Species There are 5 species in this genus: *Barbara Brown's titi monkey, ''Callicebus barbarabrownae'' * Coimbra Filho's titi monkey, ''Callicebus coimbrai'' * Coastal blac ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habit ...

Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Paraguaçu River
The Paraguaçu River () is a river in Bahia state, located in eastern Brazil. It runs from the Chapada Diamantina highlands of central Bahia to its mouth at the Baía de Todos os Santos. The Paraguaçu River is the largest river entirely within Bahia. Its banks are fertile and the cities at its mouth are navigable. It served as a main route of transportation and communication of the entire region both in the pre-Colonial and Portuguese Colonial period. Its lower reaches are home to the Baía do Iguape Marine Extractive Reserve, created in 2000. Etymology The word "Paraguaçu" is of Tupi language origin and means "great river". It is a combination of the words "pará", meaning river; and "gûasu", meaning great. In the colonial period it was variously spelled as Paraguaçu, Paraoçu, Paraossu, Peroguaçu, Perasu, Peoassu, or Peruassu.

Titi
The titis, or titi monkeys, are New World monkeys of the subfamily Callicebinae, which contains three extant genera: ''Cheracebus'', ''Callicebus'', and ''Plecturocebus.'' This subfamily also contains the extinct genera '' Miocallicebus, Homunculus'', and ''Carlocebus''. Titi monkeys live in South America, from Colombia, Ecuador and Peru, east through Brazil, and south to Bolivia and northern Paraguay. Description Depending on species, titis have a head and body length of , and a tail, which is longer than the head and body, of . The different titi species vary substantially in coloring, but resemble each other in most other physical ways. They have long, soft fur, and it is usually reddish, brownish, grayish or blackish, and in most species the underside is lighter or more reddish than the upperside. Some species have contrasting blackish or whitish foreheads, while all members of the genus ''Cheracebus'' have a white half-collar. The tail is always furry and is not prehensile. ...
