Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

Oikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
