The stress response, which involves joint activity of the nervous and endocrine systems, is
one of the basic adaptive mechanisms that ensures the survival of the individual. The …

Monitoring stress levels of farmed Atlantic salmon (Salmo salar) is important to ensure fish
welfare and optimize farm operations. Feces could be a promising matrix for assessing …

Seasonally breeding mammals must make constant adjustments in behavior and physiology
to manage energetic trade-offs between survival and reproduction. Despite encountering …

Quantifying physiological stress in wild animals is essential for understanding their health,
reproductive success, and survival in a variable environment. The yellow-bellied marmot …

Free ranging animals are exposed to environmental, demographic, and ecological
challenges over time, which can affect their health and fitness. Non‐invasive biomarkers can …

Ecological and environmental factors can influence the transmission of infectious diseases.
They can accomplish this via effects on host susceptibility and exposure to infection, which …

Male and female rodents experience different selective pressures associated with
reproductive costs. Thus, we may expect the expression of different Pace-of-life (POL) …

The stress response is highly conserved across species, and increased glucocorticoid
release (cortisol in fishes) is a key element. In the highly social cichlid fish, Burton's …

Abstract The “Cort-Fitness” hypothesis predicts a negative relationship between baseline
glucocorticoids (GCs) and fitness, although evidence for this hypothesis remains mixed …

One of the primary reasons for global species decline is environmental disturbance which
pose multiple stressors on wildlife populations. However, understanding the complex effects …
