Marine ecoregions : ウィキペディア英語版 | Marine ecoregions Marine ecoregions are ecoregions (ecological regions) of the oceans and seas identified and defined based on biogeographic characteristics. ==Introduction== A more complete definition describes them as “Areas of relatively homogeneous species composition, clearly distinct from adjacent systems” dominated by “a small number of ecosystems and/or a distinct suite of oceanographic or topographic features”. Ecologically they “are strongly cohesive units, sufficiently large to encompass ecological or life history processes for most sedentary species.”〔Spalding, Mark D., Helen E. Fox, Gerald R.
