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 …

The range of resources that a species uses (ie its niche breadth) might determine the
geographical area it can occupy, but consensus on whether a niche breadth–range size …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Functional ecology is the branch of ecology that focuses on various functions that species
play in the community or ecosystem in which they occur. This accessible guide offers the …

Humans have brought about unprecedented changes to environments worldwide. For many
species, behavioral adjustments represent the first response to altered conditions. In this …

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

This review proposes ten tentative answers to frequently asked questions about dispersal
evolution. I examine methodological issues, model assumptions and predictions, and their …

The economic and ecological effects of invasive species, notably pests (Mack et al. 2000;
Suckling and Brockerhoff 2010; Ragsdale et al. 2011), are now widely recognized (Thomas …

Biological invasions are 'natural'experiments that can improve our understanding of
contemporary evolution. We evaluate evidence for population differentiation, natural …
