Despite a wealth of studies documenting prey responses to perceived predation risk,
researchers have only recently begun to consider how prey integrate information from …

Extracellular vesicles (EVs), such as exosomes or oncosomes, often carry oncogenic
molecules derived from tumor cells. In addition, accumulating evidence indicates that tumor …

Given the current pace of climate change, high temperature events will become increasingly
frequent in many parts of the world. Predicting how high temperatures will impact the …

Little is known about how predators or their cues affect the acquisition and allocation of
energy throughout the ontogeny of prey organisms. To address this question, we have been …

Animals are expected to be judicious in the use of the energy they gain due to the costs and
limits associated with its intake. The management of energy expenditure (EE) exhibited by …

Wintering energy management in small passerines has focused on the adaptive regulation
of the daily acquisition of energy reserves within a starvation–predation trade-off framework …

Several methods are routinely used to measure avian body temperature, but different
methods vary in invasiveness. This may cause stress-induced increases in temperature …

Sex-biased infections are a recurrent observation in vertebrates. In many species, males are
more parasitized than females. Two potentially complementary mechanisms are often …

The obesity epidemic in humans is juxtaposed by observations of passerine birds exhibiting
fine-scale body mass regulation. The ecology literature is replete with research into why …

Metabolic physiology and animal behaviour are often considered to be linked, positively or
negatively, according to either the performance or allocation models. Performance seems to …
