The Scale Transition

The dynamical change that occurs with a
change in spatial or temporal scale in an
ecological community is referred to as *the scale transition*.
Scale transition theory
explains this change in dynamics as an interaction between
nonlinearities in population
growth and spatial or temporal variation in population densities and
environmental
factors. This interaction results from the phenomenon of nonlinear
averaging.
