Weeds, plants that thrive in the face of disturbance, have eluded human's attempts at control
for> 12 000 years, positioning them as a unique group of extreme stress tolerators. The most …

Climate change and biological invasions are two major global environmental challenges.
Both may interact, eg via altered impact and distribution of invasive alien species. Even …

Identifying the factors that facilitate and limit invasive species' range expansion has both
practical and theoretical importance, especially at the range edges. Here, we used …

Aim Despite recognition that realized distributions inherently underestimate species'
physiological tolerances, we are yet to identify the extent of these differences within diverse …

Johnsongrass (Sorghum halepense) is a striking example of a post-Columbian founder
event. This natural experiment within ecological time-scales provides a unique opportunity …

Invasive species are a growing global economic and ecological problem. However, it is not
well understood how environmental factors mediate invasive range expansion. In this study …

Aims Within-species genetic and phenotypic variation have well-known effects on
evolutionary processes, but less is known about how within-species variation may influence …

Species niches have been defined in different ways, variably encompassing abiotic and
biotic parameters limiting an organism's spatial distribution. Climate is often the primary …

Aims Exotic invasive species are often exposed to strong selection pressures in their new
ranges that can often lead to substantial intraspecific variation. Population differentiation in …

Aims As an exotic species colonises a new continent, it must overcome enormous
environmental variation in its introduced range. Local adaptation of introduced species has …
