Researchers working with biodiversity try to understand organisms adaptation in their environmental niche and try to provide subsidies for conscious use of natural resources by scientific organizations and government institutions. This work aims to support the cooperation among the researchers of a species distribution modeling network. The cooperation is based on sharing modeling results, whic...
