dispersion
Ecologists also study how individuals in a population are spread across an environment. This spacing of individuals within a population is called dispersion . Some species may be clumped or clustered Figure below in an area. Others may be evenly spaced Figure below . Still others may be spaced randomly within an area. The population density and dispersion have an effect on reproduction and population size. What do you think the relationship is between population density, dispersion and size?.
