Lake Bermin (sometimes spelled Bemin) is a small lake in the volcanic chain in the Southwest Region of Cameroon. It is a volcanic lake with a crater rim that rises to a height of about .〔Dickinson, C. (2005). ''(The Tilapia of Lake Bernin, Cameroon. )'' Modern Aquarium -Greater City A.S. (NY): 15-16〕 This highly isolated lake is roughly circular in shape, lacks an inflow, but has an outflow into the Cross River system.〔Schliewen, U.K., Tautz, D., and Pääbo, S. (1994). ''Sympatric speciation suggested by monophyly of crater lake cichlids.'' Nature 368(6472): 629-632.〕 Despite its very small size, it supports nine endemic species of tilapiine cichlid fishes (''C. bakossiorum'', ''C. bemini'', ''C. bythobates'', ''C. flava'', ''C. gutturosa'', ''C. imbriferna'', ''C. snyderae'', ''C. spongotroktis'', and ''C. thysi'').〔 This number of endemic fishes per area is the highest recorded anywhere.〔Freshwater Ecoregions of the World (2008). ''(Western Equatorial Crater Lakes. )''〕 Genetic evidence suggests that these probably were the result of sympatric speciation.〔 All are critically endangered by pollution and sedimentation from human activities, and potentially also by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos). ==See also== * Lake Barombi Koto * Lake Barombi Mbo * Lake Dissoni * Lake Ejagham * Lake Oku 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Bermin」の詳細全文を読む スポンサード リンク
