Phenotypic plasticity has been suggested as the main mechanism for species persistence
under a global change scenario, and also as one of the main mechanisms that alien species …

This chapter reviews what is known about how climatic variation shapes physiological traits
and in turn how this can help explain distributional range limits. Over the last decade a …

Projected rates of climate change over the next century are expected to force species to shift
ranges, adapt or acclimate to evade extinction. Predicting which of these scenarios may be …

Phenotypic plasticity is thought to be important for plants in variable environments. The
climatic variability hypothesis poses that populations at higher latitudes, due to the stronger …

In nature, birds are faced with variable food sources that may differ in composition (protein
vs. carbohydrates) and quality (highly digestible material vs. indigestible fiber). Studies in …

Macrophysiology is defined as the study of variation in physiological traits—including
physiological trait flexibility—over large geographical and temporal scales, and the …

Individual diet specialisation (IS) is frequent in many animal taxa and affects population and
community dynamics. The niche variation hypothesis (NVH) predicts that broader population …

Several studies published over the last years suggest that the ability of many species to
cope with global change will be closely related to the current amount of plasticity for fitness …

Background: The climatic variability hypothesis states that, as the range of climatic
fluctuation experienced by terrestrial animals increases with latitude, individuals at higher …

Phenotypic flexibility in metabolic rates allows organisms to reversibly adjust their energy
flow to meet challenges imposed by a variable environment. In turn, the food habits …
