Population Growth curves

Uniform dispersion pattern

• individuals are most likely interacting and equally spaced in the environment

• territorial animals do this

• seen in small groups

Clumped dispersion pattern

• resources are often unequally distributed and individuals are grouped in patches.

• individuals clumped into favorable environments

• equally spaced out
