Although range expansions have occurred recurrently in the history of most species, their
genetic consequences have been little investigated. Theoretical studies show that range …

Recent range expansions have probably occurred in many species, as they often happen
after speciation events, after ice ages, or after the introduction of invasive species. While it …

Due to past and current climatic changes, range contractions and range shifts are essential
stages in the history of a species. However, unlike range expansions, the molecular …

Species range limits involve many aspects of evolution and ecology, from species
distribution and abundance to the evolution of niches. Theory suggests myriad processes by …

We investigate the effect of spatial range expansions on the evolution of fitness when
beneficial and deleterious mutations cosegregate. We perform individual‐based simulations …

ABSTRACT A species' range limits may shift in space either because of changes in
ecological factors (eg climate, the abundances of interacting species) or because the traits …

We investigate the effect of habitat fragmentation on the genetic diversity of a species
experiencing a range expansion. These two evolutionary processes have not been studied …

Explaining the evolution of species geographical ranges is fundamental to understanding
how biodiversity is distributed and maintained. The solution to this classic problem in …

More than 100 years after Grigg's influential analysis of species' borders, the causes of limits
to species' ranges still represent a puzzle that has never been understood with clarity. The …

Most evolutionary theory does not deal with populations expanding or contracting in space.
Invasive species, climate change, epidemics, and the breakdown of dispersal barriers …
