Causes of interspecific variation in avian migration distance

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract Migration is an awe‐inspiring behavior employed by a diverse suite of taxa throughout the animal kingdom. Avian migration is arguably the most well‐known animal behavior and birds vary widely in how far they migrate, but the ecological mechanisms underlying interspecific variation in migration distance remain unclear.

Large Regional Variation in Global Impacts of Agriculture on Terrestrial Insects and Other Arthropods

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
We show that impacts of agriculture on arthropod biodiversity are notably less negative in Europe than in other regions, which we find is driven by a degraded baseline, a selection bias of reference sites, and novel species compositions in agriculture that favour widespread habitat generalists and non‐native species.

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...
