Abstract:
Understanding the ecological and evolutionary drivers of species range limitation is a central debate in evolutionary ecology with direct implications for conservation ecology. The center-periphery hypothesis (CPH) posits that species performance decreases toward range periphery, a potential mechanism to explain range limitation. However, after several decades of testing the center-periphery hypothesis, we still lack general support for this hypothesis. I combined meta-analysis, field observation, and modelling to present some of my results on the center-periphery hypothesis. While intuitive, the CPH is not common across taxa, and there is mixed support for the CPH indicating that range limitation is not a direct result of alteration of conditions toward the periphery but rather the result of the combined influences of biotic and abiotic factors on population performance across the range.
