Question

I NEED HELP WITH AFRICAN BIOMES AND WHEN I LOOK IT UP IT WONT SAY NOTHING PLEASE HELP

Answer 1

Africa’s rich diversity in habitats and biological life is reflected in the high number of terrestrial biomes that it contains: nine out of fourteen globally (Olson, et al. 2001). A biome can be defined as a region sharing similar habitats or vegetation types at a global scale. Biomes have similar climatic conditions, mainly temperature and precipitation. Their location in Africa is linked to six climatic zones, which are described in UNEP 2008. Biomes are classified within biogeographic realms. Udvardy 1975 recognizes eight global biogeographic realms, of which two are present in Africa: the Palearctic in the northern third and the Afro-tropical in the rest of the continent. There is no exact agreement as to what constitutes a particular biome, and several classifications exist; for examples for Africa, compare UNEP 2008; Adams, et al. 1996; and Burgess, et al. 2004. Here, nine terrestrial biomes are described following Burgess, et al. 2004. Within biomes, smaller units of distinct ecosystems can be distinguished. Ecoregions are units of land with distinct animal and plant communities nested within biomes and biogeographic realms. They were developed as tools for conservation. Burgess, et al. 2004 identifies 119 ecoregions of Africa in the World Wildlife Fund’s (WWF) global diversity map. A standard reference for the classification of vegetation in Africa is the White 1983 vegetation map, which recognizes seventeen major vegetation types based on structural characteristics; this has formed the basis for WWF’s ecoregions. An alternative classification is presented in Sayre, et al. 2013, which uses a modeling approach to produce a map with the potential distribution of 126 “vegetation macrogroups.” http://www.oxfordbibliographies.com/view/document/obo-9780199830060/obo-9780199830060-0112.xml
