Population ecology
Population ecology is a major subfield of ecology—one that deals with the dynamics of species populations and how these populations interact with the environment. The older term, autecology refers to the roughly same field of study, coming from the division of ecology into autecology—the study of individual species in relation to the environment—and synecology—the study of groups of organisms in relation to the environmnent—or community ecology. Odum (1959, p. 8) considered that synecology should be divided into population ecology, community ecology, and ecosystem ecology, defining autecology as essentially "species ecology." However, biologists have for some time recognized that the more significant level of organization of a species is a population, because at this level the species gene pool is most coherent. In fact, Odum regarded "autecology" as no longer a "present tendency" in ecology (i.e., an archaic term).
The development of the field of population ecology owes much to the science of demography and the use of actuarial life tables. Population ecology has also played an important role in the development of the field of conservation biology especially in the development of population viability analysis (PVA) which makes it possible to predict the long-term probability of a species persisting in a given habitat patch (e.g., a national park). While essentially a subfield if biology, population ecology provides many interesting problems for mathematicians and statisticians, which work mainly in the study of population dynamics.
