The Mediterranean Biogeographic Region is the biogeographic region around and including the Mediterranean Sea. The term is defined by the European Environment Agency as applying to the land areas of Europe that border on the Mediterranean Sea, and the corresponding territorial waters. The region is rich in biodiversity and has many endemic species.
The European Environmental Agency (EEA) divides Europe into a total of eleven terrestrial biogeographical regions and seven regional seas. [1] The agency has issued the Digital Map of European Ecological Regions (DMEER), and operates with a total of 70 ecoregions, of which 58 are within the European continent .
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
For example, Turkey is divided into the Mediterranean, Black Sea and Anatolian biogeographic regions, but it could be argued that parts of that country belong to the Alpine region. [10] For the sake of simplicity, national borders were sometimes taken as the borders between regions. [10]
This system has a strong biogeographic basis, but was designed to aid in conservation activities for marine ecosystems. Its subdivisions include both the seafloor and shelf pelagic biotas of each marine region. [1] The digital ecoregions layer is available for download as an ArcGIS Shapefile. [2]
Biogeographic realms correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. From 1872, Alfred Russel Wallace developed a system of zoogeographic regions, extending the ornithologist Philip Sclater's system of six regions. [1] Biogeographic realms are characterized by the evolutionary history of the organisms they ...
The Mediterranean basin is also one of the world's most endangered biogeographic regions; only 4% of the region's original vegetation remains, and human activities, including overgrazing, deforestation, and conversion of lands for pasture, agriculture, and urbanization, have degraded much of the region.
Physical and political map of the Mediterranean basin. In biogeography, the Mediterranean basin (/ ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED-ih-tə-RAY-nee-ən), also known as the Mediterranean region or sometimes Mediterranea, is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which ...
