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 ...

Elevating the importance of Risk of Bias assessment for ecology and evolutionary biology

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 9, Page 2559-2573, September 2026.
Abstract Systematic reviews and meta‐analyses are key evidence synthesis methods for informing future research, interventions and policy. As the validity of their conclusions depends on the primary studies they synthesise, assessing the internal validity of the included studies is essential.

Social information about others' affective states in a human‐altered world

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Managing the Threat of Subsidized Predators for a Threatened Shorebird

open access: yesAnimal Conservation, Volume 29, Issue 4, Page 443-454, August 2026.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...
