Characteristics of populations - Each population has certain characteristics: • Population size = number of individuals making up its gene pool • Population density = number of individuals per unit of area or volume, e.g., persons/square mile • Population distribution = the general pattern in which the population members are dispersed through
Ecological principles use ecological concepts (which are understood to be true) to draw key conclusions that can then guide human applications (section 3) aimed at conserving biodiversity.
Population ecologists study different species around the world for many important reasons including: • Determining which species need protection, such as endangered species • Managing economically valuable species, such as commercial fisheries • Controlling pest species and invasive species. Population ecology . is the study of these ...
