AbstractMeasuring 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 activity is needed. Here we used 15 captive Arctic foxes (both males and females and juveniles and adults) to investigate fGCM concentrations following ACTH injection (physiological validation), or handling alone and compared them with their respective baseline concentrations prior to the treatments. A 5α-pregnane-3ß,11ß,21-triol-20-one enzyme immunoassay measured significant fGCM increases following both treatments. The time lags to reach peak fGCM values were 9.3 ± 1.3 h and 12.8 ± 1.7 h for ACTH and handling treatment, respectively. Concentrations of fGCMs varied a lot between individuals, but not attributed to sex nor age of the foxes. However, we found a negative relationship between boldness and fGCM concentrations. Faecal glucocorticoid metabolites concentrations did not change significantly over a period of 48 h in samples kept at temperatures reflecting winter and summer means. This would allow the collection of samples up to two days old in the wild regardless of the season. We conclude that our successfully validated method for measuring fGCMs can be used as a non-invasive tool for studies exploring various stressors both in wild and captive Arctic foxes.

ABSTRACT Body weight, metabolic rate, locomotor activity and alterations in endocrine organ activity were noted in recessive homozygous male whirler mice and the phenotypically »normal« heterozygotes. Representative populations of the two types were studied at different age levels. In general, body weights of the whirler mice were consistently and significantly lower. Open-field locomotion studies similarly indicated heightened locomotor activity. Total leukocyte and eosinophil counts were either markedly or significantly lower in the homozygous vs. heterozygous whirler groups. Evaluation of relative organ weights showed significantly increased adrenal weights in whirler mice sacrificed at 14 weeks and 11 months of age. These changes were accompanied by involution of the thymus. Thus, the varied data indicate persistent increased metabolism and adrenocortical activity during the life-span of the whirler mice. Seminal vesicle weight decreases in the whirler males at 11 months suggest lower gonadal function. The findings are in accord with previous studies of alterations in metabolic rates and endocrine function of homozygous whirler vs. heterozygous female mice.
