Due to their limited ranges and inherent isolation, island species have long been recognized
as crucial systems for tackling a range of evolutionary questions, including in the early study …

Island systems generally have fewer species than continental areas due to their small size
and geographical isolation. Low island diversity reduces the possibility of exportation of …

When populations colonize new areas, both strong selection and strong drift can be
experienced due to novel environments and small founding populations, respectively …

Genomes retain evidence of the demographic history and evolutionary forces that have
shaped populations and drive speciation. Across island systems, contemporary patterns of …

Discerning the relative roles of adaptive and nonadaptive processes in generating
differences among populations and species, as well as how these processes interact, is a …

Colonization, speciation and extinction are dynamic processes that influence global patterns
of species richness,,,,–. Island biogeography theory predicts that the contribution of these …

DivERGENCE FoLLowiNG iSLAND CoLoNizATioN stems from the action of
microevolutionary pro cesses, including drift, selection, gene flow, and mutation (Mayr 1954 …

Given the availability of genomic data to identify separately evolving groups of organisms,
many researchers establish species limits based on assessments of the extent of gene flow …

Island species provide excellent models for investigating how selection and drift operate in
wild populations, and for determining how these processes act to influence local adaptation …

Speciation—the multiplication of species through the evolution of barriers to reproduction
between populations—plays a central role in evolution since it enables two or more …
