โฆ Synopsis
We study the large time behaviour of a nonlinear population model with a general logistic term. It is proved that every solution must have a limit when time becomes infinite. We present conditions that guarantee the boundedness of the solution. Furthermore, we prove that in general no oscillation is possible for the total number of population. This is in sharp contrast to the linear case.

Local stability seems to imply global stability for population models. To investigate this claim, we formally define a population model. This definition seems to include the onedimensional discrete models now in use. We derive a necessary and sufficient condition for the global stability of our defi
