It's time to go—Drivers and plasticity of migration phenology in a short‐distance migratory ungulate

Journal of Animal Ecology, Volume 94, Issue 6, Page 1204-1220, June 2025.
In thishis study, we reveal how vegetation phenology and snow dynamics drive the timing of migration in a short‐distance migratory ungulate inhabiting the Alps. Differences appeared between sexes, suggesting that female ibex could be constrained in their migration timing because of parturition, questioning the consequences of rapid climate change in ...

Highway underpasses offer little fragmentation relief for desert bighorn sheep near Mojave National Preserve, CA

California Fish and Wildlife Journal
To improve wildlife connectivity across the U.S., managers need to identify and prioritize movement barriers in need of mitigation. Roadway barriers may be semi-permeable and allow some movement either at-grade or via non-wildlife underpasses, but ...

Is What Comes out the Same as What Goes in? A Preliminary Investigation of the Isotopic Impacts of Digestion by Red‐Tailed Hawks (Buteo jamaicensis) and Eurasian Eagle Owls (Bubo bubo)

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Isotope analysis of predator feces and consumed prey remains can be used to non‐invasively track diet and reconstruct past environment and climate conditions. However, one must account for the isotopic difference between diet and feces, as well as the possible influence of digestion on consumed prey tissues.

Environmental DNA (eDNA) Quantitative Polymerase Chain Reaction‐Based Assays for Surveying 125 Taxa of Importance to North America

Environmental DNA, Volume 7, Issue 3, May–June 2025.
We present 125 eDNA quantitative real‐time polymerase chain reaction (qPCR) assays against animal species of importance to North America. We show how these assays were designed and validated to comply with the Canadian national eDNA standards to allow confident eDNA detection for coastal and inland ecological surveys and biosurveillance.
