Wildlife Monographs, Volume 226, Issue 1, September 2026.We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Biotropica, Volume 58, Issue 5, September 2026.ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars
Functional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Biotropica, Volume 58, Issue 1, January 2026.Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Foraging Movement Patterns of Lactating Mexican Long‐Nosed Bats in Central Mexico
Ecology and Evolution, Volume 15, Issue 9, September 2025.We tracked 21 lactating females of a migratory and endangered nectar‐feeding bat using GPS devices, and analyzed their foraging movements in one of the most important maternity roosts for the conservation of the species. Bats foraged within 50 km from the roost, made up to three foraging trips on the same night, and visited multiple foraging grounds ...
