Stanislav Semenovich Shwarts (Russian: Станислав Семенович Шварц; 1919–1976) was a prominent Ukrainian-Soviet ecologist and zoologist.
Shwarts was born in the city of Yekaterinoslav (current Dnipro, Ukraine).
In 1955 he stood at the head of this Institute and made it one of the most prolific centers of ecology in the world.
Shwarts contributed into the evolution theory and chemical ecology of the sea fauna and proposed his own definition of the notion of population which enriched the ecological niche theory.
He studied the relation between a human and the biosphere, he developed special methods for investigations in the ecology and was one of those scientists who argued the necessity of human ecology as a part of biology.
