Ungulates exhibit diverse mating systems that range from monogamous pair territories to
highly polygynous leks. We review mating systems and behaviors across ungulates and …

Bighorn sheep (Ovis canadensis) can live in extremely harsh environments and subsist on
submaintenance diets for much of the year. Under these conditions, energy stored as body …

Mammals are imperiled worldwide. Threats to terrestrial species are primarily from habitat
loss or modification, and in some instances from commercial, illegal, or unregulated hunting …

Mammals are imperiled worldwide, primarily from habitat loss or modification, and exhibit
downward trends in their populations and distributions. Likewise, large-bodied herbivores …

Food quality and availability, when combined with energetic demands in seasonal
environments, shape resource acquisition and allocation by animals and hold …

Long‐distance migration by terrestrial mammals is a phenomenon critical to the persistence
of populations, but such migrations are declining globally because of over‐harvest, habitat …

Survival in small populations (eg, Sierra Nevada bighorn sheep or Sierra bighorn [Ovis
canadensis sierrae]) is often highly variable. External selective pressures vary in the degree …

Conservation biologists have increasingly used translocations to mitigate population
declines and restore locally extirpated populations. Genetic data can guide the selection of …

Animals are inherently tied to nutritional resources of the landscape. Added cost of coping
with environmental stressors, like disease, can exacerbate nutritional limitations …

Differentially harvesting individual animals with specific traits has led some to argue that
such selection can cause evolutionary change that may be detrimental to the species …
