Webb11 feb. 2011 · It is shown that for a certain parameter range, there exists a compact interior attractor that attracts all interior points except Lebesgue measure zero set, which gives a weaker form of coexistence which is referred to as relative permanence. In this article, we study the global dynamics of a discrete two-dimensional competition model. We give … Webb22 juli 1997 · In the stable range of the Moran–Ricker dynamics, environmental noise of any colour will make population dynamics red or blue depending on the intrinsic growth rate.
