A major challenge in ecology and evolution is to disentangle the mechanisms driving broad-
scale variation in biological traits such as body size, colour, thermal physiology traits and …

Many organisms are shrinking in size in response to global warming. However, we still lack
a comprehensive understanding of the mechanisms linking body size and temperature of …

Traditional comparative studies examine evolutionary associations of traits by comparing
different species, regardless of their phylogenetic relationships. A problem with such an …

Intra-specific colour variation may either reflect a discrete polymorphism, potentially related
to life-history strategies; a continuous signal, which may be related to individual quality; or a …

Colour has many different functions in animals, such as an involvement in thermoregulation,
crypsis, and social interactions. Species capable of physiological colour change may alter …

We discuss three aspects of the thermal biology of lacertid lizards. First, we provide an
overview of the available data on field body temperatures (Tb), the thermal sensitivity of …

Solar radiation is in theory an unlimited resource on Earth, but can be locally limited.
Heliothermic organisms use solar radiation to elevate their body temperatures, leading them …

Colouration may endorse thermoregulatory and antipredatory functions in snakes. The
thermal melanism hypothesis predicts that dark-coloured individuals are ecologically …

Understanding the impacts of anthropogenic climate change requires knowing how animals
avoid heat stress, and the consequences of failing to do so. Animals primarily use behavior …

Temperature affects the physiological functions of ectotherms. To maintain optimal body
temperature and ensure physiological performance, these organisms can use behavioral …
