Abstract
The two most popular and extensively-used discrete models of population growth
display the generic bifurcation structure of a hierarchy of period- doubling sequence to
chaos with increasing growth rates. In this paper we show that these two models, though
they belong to a general class of one-dimensional maps, show very different dynamics
when important ecological processes such as immigration and emigration/depletion, are
considered. It is important that ecologists recognize the differences between these models
before using them to describe their data—or develop optimization strategies—based on
these models.
