Document Summary

The special branch of ecology which deals with the study of individuals of the same species and the related processes such as aggregation interactions between individuals and the factors leading to those processes is known as population ecology. Population is a group of individuals of a particular species, sharing the common genepool and occupying a particular area at a specific time. There are two types of populations in ecology: monospecific population (individuals of one species, mixed or polyspecific population (individuals of more than one species) A populations has the following characteristics: size and density; 2. Size is the number of individuals in a population. Density is the number per unit area (or volume) of environment. Density is further divided in to: crude density. Density (number or biomass) per unit total space: specific density (ecological density) Density (number of biomass) per unit habitat space that can actually be used by the population.
