WebEcologists often estimate the size and density of populations using quadrats and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern. ioptron 8031WebApr 9, 2024 · An ecosystem where all the species are represented by the same number of individuals has high species evenness.
