Spatial heterogeneity alters the trade-off betweengrowth and dispersal during a range expansion

The paper shows spatial heterogeneity shifts the growth-dispersal trade-off from R-strategies to D-strategies during range expansion in a fragmented environment.

Dynamics of adaptation in an anisotropic phenotype-fitness landscape

This paper analyzes adaptation dynamics in an anisotropic phenotype-fitness landscape and shows that mean fitness trajectories may exhibit plateaus before converging, fitting empirical data from E. coli evolution experiments.

When sinks become sources: adaptive colonization in asexuals

This study develops a framework to analyze the establishment of asexual populations in a sink habitat, showing how mutation and immigration rates influence success and timing.
