Avian models have the potential to elucidate basic cellular and molecular mechanisms
underlying the slow aging rates and exceptional longevity typical of this group of vertebrates …

The plight of wild birds is becoming critical due to exposure to environmental contaminants.
Although laboratory studies have provided insights into the developmental effects of …

Urban landscapes are associated with abiotic and biotic environmental changes that may
result in potential stressors for wild vertebrates. Urban exploiters have physiological …

Artificial light at night (ALAN) can disrupt adaptive patterns of physiology and behavior that
promote high fitness, resulting in physiological stress and elevation of steroid …

Parental stress often has long-term consequences for offspring. However, the mechanisms
underlying these effects and how they are shaped by conditions offspring subsequently …

Glucocorticoid (GC) hormones are significant regulators of homeostasis. The physiological
effects of GCs critically depend on the time of exposure (short vs. long) as well as on their …

Animals exposed to stressful developmental conditions can experience sustained
physiological, behavioral, and fitness effects. While extensive research shows how …

Corticosterone plays a central role in maintaining homeostasis, promoting energy
acquisition, and regulating the stress response in birds. Exposure to elevated levels of …

Colorful ornaments are important visual signals for animal communication that can provide
critical information about the quality of the signaler. In this study, we focused on different …

In wild vertebrates, young parents are less likely to successfully rear offspring relative to
older ones because of lower parental skills ('the constraint hypothesis'), lower parental …
