Abstract The 'centre–periphery hypothesis'(CPH) is a long‐standing postulate in ecology
that states that genetic variation and demographic performance of a species decrease from …

Plants are exposed to heterogeneity in the environment where new stress factors (ie, climate
change, land use change, and invasiveness) are introduced, and where inter‐and …

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 …

Aim: More powerful tests of biodiversity theories need to move beyond species richness and
explicitly focus on mechanisms generating diversity via trait composition. The rise of trait …

Ecological changes in the phenology and distribution of plants and animals are occurring in
all well-studied marine, freshwater, and terrestrial groups. These observed changes are …

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 …

▪ Abstract Contributions from the field of population biology hold promise for understanding
and managing invasiveness; invasive species also offer excellent opportunities to study …

Recent theory and empirical evidence have provided new insights regarding how
evolutionary forces interact to shape adaptation at stable and transient range margins …

Although the potential genetic risks associated with rare or endangered plants and small
populations have been discussed previously, the practical role of population genetics in …

Tree taxa shifted latitude or elevation range in response to changes in Quaternary climate.
Because many modern trees display adaptive differentiation in relation to latitude or …
