serving as the main source of food for the future embryo. Low levels of dietary lipids and fatty acids have been shown to negatively affect reproduction and offspring success in fish. Females fed a diet high in fatty acids usually have higher quality and number of viable eggs, leading to hig...
Adult male and juvenile ferrets had equivalent diets, with prairie dogs constituting nearly 75% of their assimilated diet. In contrast, adult females obtained over one third of their diet from other species, notably mice. However, female ferrets appeared to have provisioned prairie dogs to their ...
Protecting females with dependent young has therefore the potential to induce selectivity towards a lengthening of maternal care in the Scandinavian brown bear, with consequences for population generation time and age structure. Results Occurrence of maternal care tactics in the population We found that ...
The field of animal cognition has advanced rapidly in the last 25 years. Through careful and creative studies of animals in captivity and in the wild, we have gained critical insights into the evolution of intelligence, the cognitive capacities of a diverse array of taxa, and the importance of...

The theoretical optimal olfactory search strategy is to move cross-wind. Empirical evidence supporting wind-associated directionality among carnivores, however, is sparse. We examined satellite-linked telemetry movement data of adult female polar bears (
FA profiles of adult males and females varied significantly by season but there was a season by sex interaction, indicating that seasonal changes in diet differed by sex. FA profiles of adults also varied interannually, with a significant sex by year interaction. Interannuai variability may have...

Mountain lions spent 25 % (females) and 15 % (males) of the day active in areas with low recreation and 17 % (females) and 8 % (males) of the day active in areas of high recreation. We found marginal support for the prediction that COI influenced peak time of dawn activity (0.38,...
