TL;DR: The results suggest that extreme winter events can rapidly produce strong selection on natural populations at multiple biological levels that recapitulate geographic patterns of local adaptation.

TL;DR: It is demonstrated that among—population differences in arboreal sprint performance are probably genetically based, and that lizards with relatively longer limbs sprinted faster.

TL;DR: This work applied a phylogenetic approach to examine niche evolution during the radiation of Cuban trunk-ground anoles (Anolis sagrei group), which has produced 15 species in Cuba and revealed a specialist-generalist sister species pair in which the niche of one species is nested within, and much narrower than, the niches of another closely related species.

TL;DR: Phylogenetic information about the constituent lineages in a community can allow lineage effects to be factored out, thus allowing an assessment of environmental determinants of community structure and permits understanding of how communities have evolved through time.

TL;DR: It is proposed that introductions follow a sequential, two‐step process involving a reduction in genetic variation due to founder effects and population bottlenecks followed by an increase in Genetic variation if admixture of individuals from multiple native‐range sources occurs.
