The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Ectothermic animals, such as amphibians and reptiles, are particularly sensitive to rapidly
warming global temperatures. One response in these organisms may be to evolve aspects …

Metacommunity ecology links smaller-scale processes that have been the provenance of
population and community ecology—such as birth-death processes, species interactions …

Phylogenetic comparative methods comprise the general endeavor of using an estimated
phylogenetic tree (or set of trees) to make secondary inferences: about trait evolution …

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 …

The process of adaptive radiation—the proliferation of species from a single ancestor and
diversification into many ecologically different forms—has been of great interest to …

Background The extant squamates (> 9400 known species of lizards and snakes) are one of
the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have …

Many biologists are asking whether environmentally initiated phenotypic change
(ie,'phenotypic plasticity') precedes, and even facilitates, evolutionary adaptation. However …

Research on growing American political polarization and antipathy primarily studies public
institutions and political processes, ignoring private effects, including strained family ties …

Parallel evolution across replicate populations has provided evolutionary biologists with
iconic examples of adaptation. When multiple populations colonize seemingly similar …
