Body size influences many traits including those that affect host competence, the propensity
to cause new infections. Here, we employ a new framework to reveal that, for at least two …

Climate change is threatening biodiversity world-wide. One of its most prominent
manifestations are rising global temperatures and higher frequencies of heat waves. High …

Glucocorticoid (GC) variation has long been thought to reflect variation in organismal
'stress,'but associations between GCs and Darwinian fitness components are diverse in …

Variation in glucocorticoid hormones (GCs) is often interpreted as reflecting 'stress', but this
interpretation is subject of intense debate. GCs induce gluconeogenesis, and we …

Glucocorticoid (GC) hormones are important phenotypic mediators across vertebrates, but
their circulating concentrations can vary markedly. Here we investigate macroevolutionary …

As humans alter landscapes worldwide, land and wildlife managers need reliable tools to
assess and monitor responses of wildlife populations. Glucocorticoid (GC) hormone levels …

Comparative analyses have a long history of macro-ecological and-evolutionary
approaches to understand structure, function, mechanism and constraint. As the pace of …

Among a multitude of stressors to which wildlife is exposed, environmental pollution is a
pervasive one that poses a serious threat. The permeable skin of amphibians is likely to …

Glucocorticoids (GCs) are metabolic hormones that regulate physiological and behavioural
responses to environmental change and mediate homeostasis maintenance in vertebrates …

Glucocorticoid (GC) hormones have traditionally been interpreted as indicators of stress, but
the extent to which they provide information on physiological state remains debated. GCs …
