Yucatán Black Howler
The Yucatán black howler, or Guatemalan black howler, (''Alouatta pigra'') is a species of howler monkey, a type of New World monkey, from Central America. It is found in Belize, Guatemala and Mexico, in and near the Yucatán Peninsula. It lives in evergreen, semideciduous and lowland rain forests. It is also known as the baboon in Belize, although it is not closely related to the baboons in Africa. Description The Yucatán black howler is the largest of the howler monkey species and one of the largest of the New World monkeys. Yucatán black howler males are larger than those of any other Central American monkey species. On average, males weigh and females weigh . The body is between in length, excluding the tail. The tail is between long. Adults of both sexes have long, black hair and a prehensile tail, while infants have brown fur. Males over four months old have white scrotums. The Yucatán black howler shares several adaptations with other species of howler mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbara Lawrence (biologist)
Barbara Lawrence (July 30, 1909 – 1997), sometimes known as Barbara Lawrence Schevill, was an American paleozoologist and mammalogist known for her studies of canids, porpoises and howler monkeys and her work as the mammal curator at Harvard University's Museum of Comparative Zoology (MCZ). Early life and education Lawrence was born on July 30, 1909, in Boston to Theodora (née Eldredge) and Harris Hooper Lawrence, their third child. She married William E. Schevill on December 23, 1938, while still attending Vassar College, where she was awarded a bachelor's degree in 1931. Career and research After taking a position as the Curator of Mammals at the MCZ, she took her first trip to do field research on the howler monkeys of East Africa, where she returned on other trips. In 1936 and 1937, she traveled to the Philippines and Sumatra to study bats. She collaborated with her husband, William Schevill, on studies of cetacean communication and echolocation, where they made t ...

Hyoid
The hyoid bone (lingual bone or tongue-bone) () is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. It is the only bone in the human body that is not connected to any other bones nearby. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Its name is derived . Structure The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns. Body The body of the hyoid bone is the central part of the hyoid bone. *At the fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alouatta
Howler monkeys (genus ''Alouatta'', monotypic in subfamily Alouattinae) are the most widespread primate genus in the Neotropics and are among the largest of the platyrrhines along with the muriquis (''Brachyteles''), the spider monkeys (''Ateles'') and woolly monkeys (''Lagotrix''). These monkeys are native to South and Central American forests. They are famous for their loud howls, which can travel more than a mile through dense rain forest. Fifteen species are recognized. Previously classified in the family Cebidae, they are now placed in the family Atelidae. They are primarily folivores but also significant frugivores, acting as seed dispersal agents through their digestive system and their locomotion. Threats include human predation, habitat destruction, and capture for pets or zoo animals.

Muriqui
The muriquis, also known as woolly spider monkeys, are the monkeys of the genus ''Brachyteles''. They are closely related to both the spider monkeys and the woolly monkeys. The two species are the southern (''B. arachnoides'') and northern (''B. hypoxanthus'') muriquis. They are the two largest species of New World monkey New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboid ...s, and the northern species is one of the most endangered of all the world's monkeys. The muriqui is the largest monkey in South America, and it lives primarily in coffee estates in Southeastern Brazil. Males are the same size and weight as females.

Spider Monkey
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 consistes 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 durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelidae
The Atelidae are one of the five family (biology), families of New World monkeys now recognised. It was formerly included in the family Cebidae. Atelids are generally larger monkeys; the family includes the howler monkey, howler, spider monkey, spider, woolly monkey, woolly, and Muriqui, woolly spider monkeys (the latter being the largest of the New World monkeys). They are found throughout the forested regions of Central America, Central and South America, from Mexico to northern Argentina. Characteristics The Atelidae family consists of monkeys that are small to moderate in size, usually 34 to 72 cm in head-body length, with the howler monkeys being the largest members of the group, and the spider monkeys being the smallest. They have long prehensile tails with a sensitive, almost hairless, tactile pad on the underside of the Anatomical terms of location#Proximal and distal, distal part.

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Baboon Sanctuary
Community Baboon Sanctuary is a protected area in Belize. It was established in 1985 to help address the threats of agriculture, logging and hunting of the black howler monkey ('baboon') and to educate locals and visitors about the importance of biodiversity, sustainability, and to promote the economic development of the Bermudian Landing community. History On 23 February 1985, the Community Baboon Sanctuary (CBS) was founded by Dr. Robert Horwich an American primatologist and Fallet Young, a landowner on the village of Bermudian Landing. Originally created with twelve other landowners, as of 2013 there were over 200 properties involved. In 1998, the Women's Conservation Group was formed with women from the 7 villages in the Belize River Valle, directed by Jessy Young from 1998. In 2017 the group was awarded a United Nations Equator Prize for their efforts in "improving local livelihoods while safeguarding vulnerable wildlife populations".
