Aim Populations of cold-adapted species at the trailing edges geographic ranges are particularly vulnerable to negative effects climate change from combination exposure warm temperatures and high sensitivity heat. Many these predicted decline under future scenarios, but they could persist if can adapt warming climates either physiologically or behaviourally. We aim understand local variation in...

Habitat fragmentation may present a major impediment to species range shifts caused by climate change, but how it affects local community dynamics in changing has so far not been adequately investigated empirically. Using long-term monitoring data of butterfly assemblages, we tested the effects amount and distribution semi-natural habitat (SNH), moderated traits, on climate-driven turnover. We ...

A critical threshold exists when the relationship between the amount of suitable habitat and population density or probability of occurrence exhibits a sudden, disproportionate decline as habitat is lost. Critical thresholds are predicted by a variety of modeling approaches, but empirical support has been limited or lacking. We looked for critical thresholds in two pool-breeding amphibians that...
