Alouatta Coibensis Trabeata
The Azuero howler (''Alouatta coibensis trabeata'') a type of monkey that is a subspecies of the Coiba Island howler ''A. coibensis''. This subspecies is endemic to the Azuero Peninsula in Panama. The Azuero howler is distinguished primarily by its golden flanks and loins, and browner appearance on the rest of its body. Although generally considered a subspecies of ''A. coibensis'', there is some debate within the scientific community as to whether ''A. coibensis'' itself is a valid species. If not, ''A. c. trabeata'' would be considered subspecies of the mantled howler The mantled howler (''Alouatta palliata'') is a species of howler monkey, a type of New World monkey, from Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its "mantled" ..., ''A. palliata''. In that case its trinomial name would be ''A. p. trabeata''.

Barbara Lawrence (zoologist)
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 the ...

Coiba Island Howler
The Coiba Island howler (''Alouatta coibensis'') is a type of howler monkey, a type of New World monkey, endemic to Panama. Although the Coiba Island howler has been recognized as a separate species by a number of authorities since a 1987 study of its fingerprints, mitochondrial DNA testing found it does not differ from mantled howler populations in any significant way. A reason given for treating it as a separate species is that the dermal ridges of its hands and feet differ from those of the mantled howler. ''A. c. coibensis'' is smaller than other Central American howler monkeys and has duller pelage than the Azuero howler, ''Alouatta coibensis trabeata''. Subspecies Two subspecies of this howler have been recognized by those who consider it a separate species: *''Alouatta coibensis coibensis'' Thomas, 1902, found on Coiba Island and Jicaron, off the Pacific coast of Panama *Azuero howler, ''A. c. trabeata'' Lawrence, 1933, endemic to the Azuero Peninsula Azuero Peninsula ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azuero Peninsula
Azuero Peninsula ( es, Península de Azuero) is a large peninsula in southern Panama. It is surrounded by the Pacific Ocean in the south; the Pacific and Gulf of Montijo to the west, and by the Gulf of Panama in the east. The peninsula is effectively divided into two regions; the Western Azuero and the Eastern Azuero, as no serviceable roads join the two peninsula regions past the Pan-American Highway. The Eastern Azuero Peninsula is known for baseball and is also a center of activity during the annual ''carnaval'' (carnival), with Las Tablas being the hub. Pedasi is a small fishing town with sport fishing. The Western Azuero Peninsula is known for its cattle ranching, farming, fishing, sunsets and beaches. Tourism has begun to increase in the area both for the aforementioned sport fishing, surfing and for the local charm of cities like Chitré, Las Tablas and Pedasi. Due to a rise in tourism, real estate development has begun. The area enjoys some of the best weather in Panam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

Mantled Howler
The mantled howler (''Alouatta palliata'') is a species of howler monkey, a type of New World monkey, from Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its "mantled" name from the long guard hairs on its sides. The mantled howler is one of the largest Central American monkeys, and males can weigh up to . It is the only Central American monkey that eats large quantities of leaves; it has several adaptations to this folivorous diet. Since leaves are difficult to digest and provide less energy than most foods, the mantled howler spends the majority of each day resting and sleeping. The male mantled howler has an enlarged hyoid bone, a hollow bone near the vocal cords, which amplifies the calls made by the male, and is the reason for the name "howler". Howling allows the monkeys to locate each other without expending energy on moving or risking physical confrontation. The mantled howler lives in groups ...

Primates Of Central America
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. 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 used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Howler Monkeys
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.

Mammals Described In 1933
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they Genetic divergence, diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant taxon, extant species of mammals have been described divided into 29 Order (biology), orders. The largest Order (biology), orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, Mole (animal), moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, pinniped, seals, and others).
