Geographical distributions of terrestrial or freshwater taxa that are broken up by oceans can
be explained by either oceanic dispersal or vicariance in the form of fragmentation of a …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

Island biogeography is the study of the distribution and dynamics of species in island
environments. Due to their isolation from more widespread continental species, islands are …

Aims The 50th anniversary of the publication of the seminal book, The Theory of Island
Biogeography, by Robert H. MacArthur and Edward O. Wilson, is a timely moment to review …

Evolutionary theory has gained tremendous insight from studies of adaptive radiations. High
rates of speciation, morphological divergence, and hybridization, combined with low …

Community ecology: the study of the patterns and processes involving two or more species-
has developed rapidly in the last two decades, driven by new and more sophisticated …

Abstract Aim MacArthur and Wilson's dynamic equilibrium model of island biogeography
provides a powerful framework for understanding the ecological processes acting on insular …

Island biogeographical models consider islands either as geologically static with biodiversity
resulting from ecologically neutral immigration–extinction dynamics, or as geologically …
