PPT-Population dynamics with multiple limiting nutrients: Life

Romain Richard André de Roos Development Population community processes From individual development to population dynamics Development is a major determinant of population dynamics Life history. Aas long as organisms have all of these things available to them their population will continue to grow However populations cannot grow forever Some form of environmental resistance will stop the population s growth The form of environmental resis Image from Wikimedia Commons.
