Understanding how behavioral variation emerges during early development is essential for interpreting individual differences and their ecological relevance. Early-life behavioral development can involve substantial individual variation shaped by biological and social contexts, resulting in differing levels of repeatability across behaviors. In captive-breeding programs, identifying these developmental patterns and their causes...

Humans have relied on animal fur for centuries, yet fur farming only began recently during the mid‐19th Century. Little is known about this incipient domestication or the genomic processes involved. Domestication may involve founder effects, population bottlenecks and low population size, which, when combined with intense artificial selection, lead to inbreeding, a limited gene pool and reduced fitness. The arctic fox ( Vulpes...

Measuring fecal glucocorticoid metabolites (fGCMs) is a widely used, non-invasive method for studies of stress in vertebrates. To study physiological responses in wild Arctic foxes ( Vulpes lagopus ) to perceived stressors such as fluctuating food availability, occurrence of competitors and predators and disturbance from human activities, a species-specific physiological validation of a method to evaluate adrenocortical activi...

The southern Norwegian wolverine ( Gulo gulo ) population was considered functionally extinct in the 1960s but has partly recovered in recent years. Proper management of this population is highly dependent on reliable estimates of critical population parameters such as population size, sex ratio, immigration rate, and reproductive contribution from immigrants. We report on a large‐scale population monitoring project assessing...
