Population ecology  is the study of populations in relation to the environment,  including environmental influences on population density and distribution, age  structure, and population size. Concept 52.1 Dynamic biological processes influence population density, dispersion, and demography population  is a group of individuals of a single species that live in the same  general area. Members of a population rely on the same resources, are influenced by similar  environmental factors, and have a high likelihood of interacting with and breeding  with one another. Populations can evolve through natural selection acting on heritable variations  among individuals and changing the frequencies of various traits over time. Two important characteristics of any population are density and the spacing of individuals. Every population has a specific size and specific geographical boundaries. The
