Abronia Graminea
The Mexican alligator lizard (''Abronia graminea''), also known as the green arboreal alligator lizard, is an Endangered species, endangered species of lizard Endemism, endemic to the Sierra Madre de Oaxaca highlands of Mexico. It can be found in the states of Puebla, Veracruz, and Oaxaca. It was originally described under the genus ''Gerrhonotus'' as ''Gerrhonotus gramineus'' by Edward Drinker Cope, Edward D. Cope in 1864. The Mexican alligator lizard adopts an Arboreal locomotion, arboreal lifestyle and is commonly found inhabiting the Bromeliaceae, bromeliads among mesic Cloud forest, cloud or Pine-oak Forests, Puebla, Mexico, pine-oak forest canopies. This habitat offers a humid temperate climate with summer rains. The preferred diet of this species is a variety of insects. Colour patterns of the Mexican alligator lizard can range from bright emerald green to dark teal blue; juvenile colouration is a tan ground colour with dark crossbands. The IUCN rates the Mexican alligator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oaxacan Montane Forests
The Oaxacan montane forests is a tropical moist broadleaf forest ecoregion in eastern Mexico. It includes a belt of montane tropical forest on the eastern slope of the Sierra Madre de Oaxaca and eastern Trans-Mexican Volcanic Belt ranges. These forests lie between the lowland Petén–Veracruz moist forests and Veracruz moist forests, and the pine–oak forests of the higher mountains. Geography The Oaxacan montane forests extend along eastern mountain slopes of Puebla, Veracruz and Oaxaca states. The ecoregion extends from the Tecolutla River in the north across the Sierra de Chiconquiaco, the eastern Trans-Mexican Volcanic Belt, and the Sierra Madre de Oaxaca. Climate The climate of the ecoregion is tropical, humid, and montane. The ecoregion is humid throughout the year, and temperatures remain mild, with mean annual temperature ranging from 19 °C to 17 °C, decreasing with elevation. There are three seasons: a cool season from November to March, a short warm-dry season in A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keeled Scales
Keeled scales refer to reptile scales that, rather than being smooth, have a ridge down the center that may or may not extend to the tip of the scale, Campbell, J. A., Lamar, W. W. (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 870 pp. 1,500 plates. . making them rough to the touch. According to Street's (1979) description of European lizards and snakes, in those that have keeled scales the keels are usually stronger in male specimens and are consistently arranged according to the species of reptiles, even though many others do not have them. With European lizards, the dorsal scales are usually well keeled, while those on the flanks are more weakly keeled and those on the belly smooth. Street, D. (1979). ''The Reptiles of Northern and Central Europe''. London: B.T. Batsford Ltd. 268 pp. . Non-European lizards such as ''Sphaerodactylus macrolepis'' also display keeled scales.

Sublabial Scale
In reptiles, the sublabial scales, also called lower-labials or infralabials, are those scales that border the mouth opening along the lower jaw. They do not include the median scaleWright AH, Wright AA. 1957. ''Handbook of Snakes''. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . (mental scale). The term ''labial'' originates from ''labium'' (Latin for "lip"), which refers to any lip-like structure.

Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body c ...

Prehensile Tail
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contrast, less dense forests such as in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
