The land was ice-covered until 10,000 years ago, and species diversity is still lower than other European biogeographic regions, but wildlife is abundant, including large flocks of migratory birds and many marine organisms fed by nutrients carried by the Gulf Stream from the Caribbean. [2]
They are named after Alan R. Longhurst, the author of "Ecological Geography of the Sea", the textbook in which these codes are defined. [ 3 ] These codes have also been used in bioinformatic databases such as IMG to represent sample origins for sequenced microbial genomes , as a supplement to latitude and longitude coordinate metrics .
Macaronesia (Portuguese: Macaronésia; Spanish: Macaronesia) is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. [1] [2] Each archipelago is made up of a number of Atlantic oceanic islands, which were formed by seamounts on the ocean floor whose peaks have risen above the ocean's ...
This is the Atlantic Arc Commission. [12] Operative since 1989, it includes 26 regions from four member States - Great Britain, France, Spain and Portugal. The Atlantic Arc Commission is one of the seven Geographical Commissions in the Conference of Peripheral Maritime Regions of Europe. [13]
Biogeographic realms are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes , also known as major habitat types, which are divisions of the Earth's surface based on life form , or the adaptation of animals, fungi, micro-organisms and plants to climatic, soil , and other conditions.
USGS map colored by paleogeological areas and demarcating the sections of the U.S. physiographic regions: Laurentian Upland (area 1), Atlantic Plain (2-3), Appalachian Highlands (4-10), Interior Plains (11-13), Interior Highlands (14-15), Rocky Mountain System (16-19), Intermontane Plateaus (20-22), & Pacific Mountain System (23-25) The legend ...
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Biogeography now incorporates many different fields including but not limited to physical geography, geology, botany and plant biology, zoology, general biology, and modelling. A biogeographer's main focus is on how the environment and humans affect the distribution of species as well as other manifestations of Life such as species or genetic ...
