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 ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal 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. The most concentrated deforestation occurs in tropical rainforests. 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, a 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. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Mexican Howler
The Mexican howler (''Alouatta palliata mexicana'') is a subspecies of the mantled howler, ''A. palliata''. This subspecies is found predominantly in forests between south eastern Mexico and north eastern Peru. Typical of its species, the Mexican howler monkey has a prehensile tail, a deep jaw, and a large pharynx which it uses to make characteristically deep and resonating howls. Mantled howler monkeys are known for forming unusually large cohorts averaging 14 members and sometimes extending to 40 members. Taxonomy There are five subspecies of the ''A. palliata'' which are ''Alouatta palliata aequatorialis'', ''Alouatta palliata coibensis'', ''Alouatta palliata palliata'', ''Alouatta palliata trabeata'' and ''Alouatta palliata mexicana''. Compared with members of the howler monkey genus, the Mexican howler is sympatric with the Guatemalan black howler, ''A. pigra'', in Tabasco, Mexico. The Mexican howler differs from the golden-mantled howler, ''A. palliata palliata'', primarily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden-mantled Howler
The golden-mantled howler (''Alouatta palliata palliata'') is a subspecies of the mantled howler, ''A. palliata''. It ranges throughout much of Central America, in Guatemala, Honduras, Nicaragua and Costa Rica, and possibly Panama. The range limits between the golden-mantled howler and the Ecuadorian mantled howler are not entirely clear. The Ecuadorian mantled howler replaces the golden-mantled howler in either extreme eastern Costa Rica or western Panama. The golden-mantled howler differs from the Ecuadorian mantled howler primarily by being darker, with a mantle that is more rufous than yellowish. The golden-mantled howler differs from the Mexican howler monkey primarily in aspects of skull morphology.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pallium
The pallium (derived from the Roman ''pallium'' or ''palla'', a woolen cloak; : ''pallia'') is an ecclesiastical vestment in the Catholic Church, originally peculiar to the pope, but for many centuries bestowed by the Holy See upon metropolitans and primates as a symbol of their conferred jurisdictional authorities, and still remains a papal emblem. In its present (western) form, the pallium is a long and "three fingers broad" (narrow) white band adornment, woven from the wool of lambs raised by Trappist monks. It is donned by looping its middle around one's neck, resting upon the chasuble and two dependent lappets over one's shoulders with tail-ends (doubled) on the left with the front end crossing over the rear. When observed from the front or rear the pallium sports a stylistic letter 'y' (contrasting against an unpatterned chasuble). It is decorated with six black crosses, one near each end and four spaced out around the neck loop. At times the pallium is embellished fore, ...

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 Ceboidea ( ...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.
