From: Density-regulated population dynamics and conditional dispersal alter the fate of mutations occurring at the front of an expanding population

Figure 2

Conditional dispersal strategies. (a) For density-dependent emigration, the emigration rate depends on the relation of population size and carrying capacity. This dependency can be linear (Φemi=1), concave (Φemi<1) or convex (Φemi>1). Emigration rates never exceed 0.5. (b) For density-dependent immigration, the transfer probability to any one possible destination patch depends upon its population density relative to the three other potential patch destinations (four-neighbourhood dispersal). This dependency can be linear (Φimmi=1), concave (Φimmi>1) or convex (Φimmi<1).
