Determinants of fish species composition in Abashiri River
نویسندگان
چکیده
Because natural organisms are a part of the factors constituting the ecosystem for each organism, it is important to clarify both physical and biological exploitable factors to determine species compositions which exist in that ecosystem. The variation in factors which constitute an ecosystem makes up the variation in species composition. At the same time, each species will interact and will make a dynamic ecosystem.
