Global climate change has increased average environmental temperatures world-wide,
simultaneously intensifying temperature variability and extremes. Growing numbers of …

Climate change is forcing species to migrate to cooler temperatures at higher elevations, yet
many taxa are dispersing slower than necessary. One yet-to-be-tested explanation for …

Ecological and evolutionary theories have proposed that species traits should be important
in mediating species responses to contemporary climate change; yet, empirical evidence …

Biologists have long wondered how sexual ornamentation influences a species' risk of
extinction. Because the evolution of condition‐dependent ornamentation can reduce …

Cities, through the generation of urban heat islands, provide a venue for exploring
contemporary convergent evolution to climatic warming. We quantified how repeatable the …

The impact of climate change on populations will be contingent upon their contemporary
adaptive evolution. In this study, we investigated the contemporary evolution of four …

Body size is a key functional trait that has declined in many biological communities, partly
due to changes in individual growth rates in response to climate warming. However, our …

Species vary in their ability to adapt to rapid changes, with the presence of genetic variation
often facilitating long-term evolutionary responses. Given the impending threat of climate …

Climate change pushes species polewards and upwards–as temperatures rise, species
move to areas that were previously too cold for them. During range expansions, species …

Résumé Le manteau neigeux constitue un élément clé des paysages nordiques en hiver et
peut affecter les espèces qui y vivent de multiples façons. Les processus hivernaux qui …
