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 ...

The niche variation hypothesis predicts hunting returns across human cultures

Oikos, EarlyView.
The niche variation hypothesis (NVH) proposes that a broader population niche arises from greater individual specialization. Despite decades of empirical testing, research remains constrained to non‐human foragers, and the generality of NVH may extend beyond wildlife. The analysis of > 8000 hunting records from 12 human societies across four continents

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

Oikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.
