Understanding range limits is a fundamental problem in ecology and evolutionary biology. In
1963, Mayr argued that “contaminating” gene flow from central populations constrained …

Eco‐evolutionary dynamics are now recognized to be highly relevant for population and
community dynamics. However, the impact of evolutionary dynamics on spatial patterns …

Monitoring the elevation limits of non-native species is a potentially sensitive means of
detecting effects of environmental change on invasion dynamics and species ranges. The …

Dispersal is known to play a crucial role in the formation of species' ranges. Recent studies
demonstrate that dispersiveness increases rapidly during the range expansion of species …

Knowledge about the mechanisms of range formation is crucial for scientifically based
species conservation strategies in the face of ongoing global climate change. In recent years …

Margins of the geographic distributions of species are important regions in terms of
ecological and evolutionary processes, including the species' response to climate change …

Aim Differences in phenological timing might explain why populations of the annual Lactuca
serriola reach higher elevational limits in a part of its introduced range than in its native …

Climate change causes considerable shifts in the geographic distribution of species
worldwide. Most data on range movements, however, derive from relatively short periods …

A survey of the region eastward of Nantucket provided an opportunity to examine the cold
temperate–boreal boundary along the high‐energy Great South Channel. Here described …

The establishment and spreading of biological populations depends crucially on population
growth at low densities. The Allee effect is a problem in those populations where the per …
