Zoology is the study of all of the many forms of animal life. These forms range from microscopic planktonic species to the largest fauna that inhabit the seas and land. As a division of biology, the field of zoology involves the entirety of animal taxonomy or the familial tree of all fauna.
The discipline of zoological study encompasses animal locomotion, feeding behavior, social behavior, reproductive behavior, and all other animal species characteristics as well as morphology.
The term zoology derives from the Greek words zōon (or animal) and logos (or knowledge).

Southern Pacific dry forestsLast Updated on 2013-11-23 13:16:48The Southern Pacific dry forests ecoregion is situated along the southeastern versant of the Sierra Madre del Sur Mountains including the Pacific Ocean coastal plain. These forests are a key locus of endemism for butterflies, and has the greatest diversity of scorpions and spiders in the entirety of Mexico. This ecoregion is classified in the Tropical and Subtropical Dry Broadleaf Forests biome. The Southern Pacific dry forests exhibit a moderate to high faunal species richness; for example, there are a total of 744 vertebrate taxa recorded in the ecoregion, with a particularly large number of endemic reptiles.
However, little of the original habitat is extant, since agriculture development for fruit and coffee plantations has occurred on a broad scale. Also, overgrazing by sheep has severely degraded vegetation and produced widespread soil erosion.

Panamanian dry forestsLast Updated on 2013-11-04 17:59:07The Panamanian dry forests ecoregion occupies approximately 2000 square miles of coastal and near-coastal areas on the Pacific side of Panama, around portions of the Gulf of Panama.
Originally, the Panama dry forests were distributed exclusively in the lower and premontane portions of the Pacific versanta region of land sloping in one general direction (0-800 metres in elevation), around the Gulf of Panama;. This ecoregion has a dry climate and intermediate flora diversity, which is distributed in distinct areas, such as small residual deciduous and semi-deciduous forests and gallery forests along the rivers.
Habitat destruction of this ecoregion has been extensive, with overgrazing, agricultural conversion and urbanization and resultant fragmentation, strong pressure for cattle ranching, burning, and hunting.This process of habitat destruction began in earnest with the Spanish... More »
Lesser Sundas deciduous forestsLast Updated on 2013-11-01 16:42:15The Lesser Sundas deciduous forests are found on a string of volcanic islands. They stretch across the Java Sea between Australia and Borneo. It is part of a unique biogeographic region known as Wallacea, which contains a very distinctive fauna representing a mix of Asian and Australasian species. These distinctive seasonal dry forests harbor unique species, including the Komodo dragon, the largest lizard in the world, and seventeen bird species found nowhere else on Earth. A combination of shifting agriculture and human-caused fires has significantly reduced the amount of natural forest in this ecoregion.
This ecoregion represents the semi-evergreen dry forests in the Lesser Sunda Islands. It extends east from the islands of Lombok and Sumbawa to Flores and Alor in the Indonesian Archipelago. Rinjani volcano on Lombok is the highest mountain in the ecoregion, at 3726 meters... More »
Windward Islands dry forestsLast Updated on 2013-11-01 10:33:27The Windward Islands dry forests ecoregion is sparsely distributed among the Windward Island Group of the Caribbean’s Lesser Antilles. It is typically found as an intermediate gradient between the more mesichabitat characterized by moderate soil moisture, high-elevation forests and the xeric, coastal areas. Much of this ecoregion has been substantially altered by shifting cultivation. Many areas that were once dry evergreen or semi-evergreen seasonal forest, are now cultivated and dominated by farms, rural villages, roads, pastures and banana tree patches. This ecoregion shares flora and fauna with adjacent moist forests and, in some areas, with species native to coastal habitats. Arid coastal areas and inaccessible interior mountains put a disproportionate amount of human-related pressures (i.e., agricultural expansion, roads, buildings) on this ecoregion. Consequently,...

Florida Black BearLast Updated on 2013-10-29 16:30:17When the American black bear (Ursus americanus) in Florida was first scientifically described in 1896 by naturalist C. Hart Merriam, he thought its long skull and highly arched nasal bones distinguished it from black bears in other areas and classified it as a separate species (Ursus floridanus), which he called the Everglades bear. Subsequent analyses around 1960 revised the status of these bears to the Florida black bear (U. a. floridanus), one of 16 recognized subspecies .
Species:-- Ursus americanus Pallas, 1780
