Population ecology
Population Ecology
Population ecology (pronunciation: /ˌpɒpjʊˈleɪʃən iːˈkɒlədʒi/) is a subfield of ecology that deals with the dynamics of species populations and how these populations interact with the environment. It is the study of how the population sizes of species change over time and space.
Etymology
The term "population ecology" is derived from the Latin populatio meaning "the act of peopling" and the Greek oikos meaning "house". Thus, it refers to the study of "households" of nature.
