Ecology and Evolution, Volume 16, Issue 9, September 2026.Ecological connectivity in freshwater ecosystems can be structured by river network, the terrestrial geography, and environmental conditions. In the Lower Colorado River Basin, aquatic invertebrate communities are influenced by all three dynamics, and environmental heterogeneity is the strongest observed driver of community composition.

Ecosphere, Volume 17, Issue 9, September 2026.Abstract The increasing frequency and intensity of droughts due to climate change poses a severe threat to the persistence of desert amphibians that require standing water to breed. In portions of the Sonoran Desert, tinajas (i.e., ephemeral rock pools that are filled by rain), which serve as the primary natural breeding sites for these amphibians, are

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.Using a newly expanded debris‐flow inventory, we calibrate a new set of region‐specific logistic models for predicting the likelihood of, and rainfall thresholds for, runoff‐generated postfire debris flows. The updated models consistently outperform a previous model and can improve assessment of debris‐flow hazards for burned areas across the western ...

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