This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn (23.4378° N and 23.4378° S, respectively). The tropical climate experiences hot, humid weather and rainfall year-round.
List of ecoregions in North America (CEC) List of ecoregions in the United States (EPA) Ecoregions of the world defined by the conservation group World Wildlife Fund (WWF) : Global 200 ecoregions (WWF), 238 single or combined ecoregions identified by the World Wildlife Fund (WWF) as priorities for conservation.
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.
Its main objectives are to support conservation, resource use, and management decisions by evaluating all the world's ecosystems by 2025. The Red List of Ecosystem was developed by the International Union for Conservation of Nature (IUCN), the same entity that created the Red List of Threatened Species, a global framework to monitor the level ...
Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity. Habitat fragmentation caused by geological processes such as volcanism and climate change occurred in the past, and have been identified as important drivers of speciation. [ 10 ]
However, tropical forests are extensive, making up just under half the world's forests. [3] The tropical domain has the largest proportion of the world's forests (45 percent), followed by the boreal, temperate and subtropical domains. [4] More than 3.6 million hectares of virgin tropical forest was lost in 2018. [5] [6]
Tropicality gained renewed interest in geographical discourse when French geographer Pierre Gourou published Les pays tropicaux (The Tropical World in English), in the late 1940s. [15] Tropicality encompassed two major images. One, is that the tropics represent a 'Garden of Eden', a heaven on Earth, a land of rich biodiversity or a tropical ...
