IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

American Kestrel
The American kestrel (''Falco sparverius'') is the smallest and most common falcon in North America. Though it has been called the American sparrowhawk, this common name is a misnomer; the American kestrel is a true falcon, while neither the Eurasian sparrowhawk nor the other species called sparrowhawks are in the '' Falco'' genus, hence genetically unrelated to the American kestrel. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It also ranges to South America and is a well-established species that has evolved into 17 subspecies adapted to different environments and habitats throughout the Americas. It exhibits sexual dimorphism in size (females being moderately larger) and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful and attractive, and juveniles are similar in plumage to adults. The American kestrel usually hunts in energy-cons ...

Reptiles Of Saint Martin (island)
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and amniotic development. Living traditional reptiles comprise four orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia ( ), which corresponds to common usage. Modern cladistic taxonomy regards that group as paraphyletic, since genetic and paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among reptiles from an evolutionary perspective. Many cladistic systems therefore redefine Reptilia as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lizards Of The Caribbean
Lizard is the common name used for all squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The grouping is paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling '' Draco'', are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mamma ...

Macmillan Publishers
Macmillan Publishers (occasionally known as the Macmillan Group; formally Macmillan Publishers Ltd in the United Kingdom and Macmillan Publishing Group, LLC in the United States) is a British publishing company traditionally considered to be one of the Big Five (publishers), "Big Five" English language publishers (along with Penguin Random House, Hachette Book Group USA, Hachette, HarperCollins and Simon & Schuster). Founded in London in 1843 by Scottish brothers Daniel MacMillan, Daniel and Alexander MacMillan (publisher), Alexander MacMillan, the firm soon established itself as a leading publisher in Britain. It published two of the best-known works of Victorian-era children's literature, Lewis Carroll's ''Alice's Adventures in Wonderland'' (1865) and Rudyard Kipling's ''The Jungle Book'' (1894). Former Prime Minister of the United Kingdom, Harold Macmillan, grandson of co-founder Daniel, was chairman of the company from 1964 until his death in December 1986. Since 1999, Macmi ...

Niche Differentiation
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anolis Pogus
''Anolis pogus'', the St. Martin anole, Anguilla Bank bush anole or bearded anole, is a species of anole lizard from the Caribbean island of Saint Martin, located in the Lesser Antilles. Its range used to include Anguilla, but it is now extirpated there. It may also have occurred on Saint Barthélemy. Males reach a maximum of in snout-to-vent length. Males have a uniform light brown to orange-brown dorsal surface, with an off-white to yellowish ventral surface. It has a turquoise area around its eye, which may extend to its upper head, and occasionally with an otherwise rust-brown head. Females are duller in color, but are marked with a mid-dorsal stripe, and sometimes also a white flank stripe. ''A. pogus'' coexists throughout much of its range with '' A. gingivinus'', though they appear to fill different niches, for example by ''A. pogus'' preferring lower and less exposed perches. Previously described as a subspecies of '' A. wattsi'', it was elevated to species level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anolis Carolinensis
''Anolis carolinensis'' or green anole () (among other names below) is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific Ocean, Pacific and Caribbean Sea, Caribbean. A small to medium-sized lizard, the green anole is a Anolis ecomorphs, trunk-crown ecomorph and can change its color to several shades from brown to green. Other names include the Carolina anole, Carolina green anole, American anole, American green anole, North American green anole and red-throated anole. It is commonly called chameleon in the southeastern United States and sometimes referred to as the American chameleon (typically in the pet trade) due to its color-changing ability; however, it is not a true Chamaeleonidae, chameleon. Taxonomy ''Anolis carolinensis'' is a species of the large lizard genus ''Anolis'' within the family Dactyloidae (anole lizards). This species was named by Friedrich Siegmund Voigt (1781-1850) in 1832. Phylogene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...
