Predicting species range shifts in response to environmental change requires the determination of regions where individuals maintain a positive energy budget. For hibernating animals, this budget depends on two physiological states (normothermy and torpor) that alternate in response to ambient temperature. To study range shifts of hibernators like the common noctule ( Nyctalus noctula ), we developed an ecophysiological approa...

Sexual dimorphism in plants may emerge as a result of sex‐specific selection on traits enhancing access to nutritive resources and/or to sexual partners. Here we investigated sex‐specific differences in selection of sexually dimorphic traits and in the spatial distribution of effective fecundity (our fitness proxy) in a highly dimorphic dioecious wind‐pollinated shrub, Leucadendron rubrum . In particular, we tested for the eff...

Concern about climate change has intensified interest in understanding how climatic variability affects animal life histories. Despite such effects being potentially most dramatic in large, long‐lived, and slowly reproducing terrestrial mammals, little is known of the effects of climatic variation on survival in those species. Asian elephants ( Elephas maximus ) are endangered across their distribution, and inhabit regions cha...
