Why do populations fluctuate around the carrying capacity rather than staying smooth as suggested by the logistic growth model? How is this related to growth rate and generation time? Explain how delayed density dependence is related to timing of resources and reproduction. Explain on demographic stochasticity and environmental stochasticity are connected to small population sizes and the Allee effect?

Communities and Ecosystems

Ecology contains two words: Eikos means dwelling, and logy means to study, so the combined meaning is studying habitat or living.
