| summary | In a seminal 1997 paper, Kirkpatrick and Barton (KB) proposed a system of reaction-diffusion equations coupling a species' range dynamics with adaptation to a heterogeneous environment. Their model and its generalizations have typically been studied through numerical simulations, while proving resistant to rigorous analysis and difficult to test empirically. Here we survey (1) a proof of the existence of traveling waves and localized stationary solutions to the KB system; (2) recent work on the behavior of two competing species under selection in a spatially heterogeneous environment; (3) further recent work putting key conclusions of the original KB paper to an (as yet rare) empirical test. |
