Hibernation is widely regarded as an adaptation to seasonal energy shortage, but the actual
influence of energy availability on hibernation patterns is rarely considered. Here we review …

Projected effects of climate change on animal distributions primarily focus on consequences
of temperature and largely ignore impacts of altered precipitation. While much evidence …

In The Black-Tailed Prairie Dog, John L. Hoogland draws on sixteen years of research at
Wind Cave National Park, South Dakota, in the United States to provide this account of …

Pronghorn antelope are the fastest runners in North America, clocked at speeds of up to 100
kilometers per hour. Yet none of their current predators can come close to running this fast …

1. I present a conceptual model that predicts the proximate and ultimate factors that
determine whether a mammal species has the potential to be regulated by intrinsic …

Within individual iteroparous mammals, a high rate of reproduction in early life may occur at
the cost of decreased reproduction near the end of life, leading to reproductive senescence …

White-nose syndrome (WNS) is a new disease of bats that has devastated populations in
eastern North America. Infection with the fungus, Geomyces destructans, is thought to …

Many species hibernate to conserve energy during periods of low food and water
availability. It has long been assumed that the optimal hibernation strategy involves long …

Reproduction in social organisms is shaped by numerous morphological, behavioural and
life‐history traits such as body size, cooperative breeding and age of reproduction …

Summary 1 Three hypotheses have been advanced to account for age‐related improvement
in performance: the selection hypothesis predicts improved due to the loss of lower quality …
