Evidence That Metapopulation Dynamics Maintain a Species' Range Limit

open access: yesEcology Letters, Volume 28, Issue 5, May 2025.
The metapopulation hypothesis for species range limits posits that a range limit may be imposed by subtle variation in rates of either patch colonisation or extinction. Using a multi‐year survey across ~900 km of the Pacific coast of the USA, we found evidence for key predictions made by the metapopulation hypothesis using coastal dune endemic ...
