Global climate change has increased average environmental temperatures world-wide,
simultaneously intensifying temperature variability and extremes. Growing numbers of …

Hormones are highly responsive internal signals that help organisms adjust their phenotype
to fluctuations in environmental and internal conditions. Our knowledge of the causes and …

Organisms are experiencing higher average temperatures and greater temperature
variability because of anthropogenic climate change. Some populations respond to changes …

Glucocorticoid hormones are important regulators of metabolic processes, and of the
behavioral and physiological responses to stressors. Within-population variation in …

Responding appropriately to changing conditions is crucial in dynamic environments.
Individual variation in the flexibility of physiological mediators of phenotype may influence …

Environmental temperature has profound effects on animal physiology, ecology, and
evolution. Glucocorticoid (GC) hormones, through effects on phenotypic performance and …

A challenge to ecologists and evolutionary biologists is predicting organismal responses to
the anticipated changes to global ecosystems through climate change. Most evidence …

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

In many organisms, rapidly changing environmental conditions are inducing dramatic shifts
in diverse phenotypic traits with consequences for fitness and population viability. However …

Circulating glucocorticoid hormone concentrations are dynamic, flexible, and promote
adaptive responses following perturbations in an animal's environment. As a result …
