A Modern Metrical Baseline for Sexing Sheep Horn‐Cores

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages.

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges

Oikos, EarlyView.
Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.
