Predictive Models for Postfire Debris Flow Initiation in the Southwest USA

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Postfire debris flows pose a threat to life and infrastructure and significantly contribute to sediment supply in upland channels, thereby impacting water quality, stream habitats, and landscape evolution. Models designed to assess postfire debris‐flow likelihood at the watershed scale in response to design or forecast rainstorms are ...

Contrasting direct and indirect effects of roe deer on herb layer vegetation in gaps and closed canopies

open access: yesJournal of Ecology, Volume 114, Issue 6, June 2026.
Forest gaps primarily reshape herb layer composition by increasing light availability and shrub layer encroachment. Roe deer influence herb layer community assembly both directly and indirectly via modification of the shrub layer and light availability and thus shifting plant–plant competition.

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 6, Page 1880-1895, June 2026.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

(In)determinacy in Woody Plants: Limits and Opportunities for Timing Growth in a Changing Climate

open access: yesEcology Letters, Volume 29, Issue 6, June 2026.
Tree growth is shaped not only by temperature and water availability, but also by intrinsic developmental programming that constrains when and how long meristems remain active. We use (in)determinacy—the continuum from fixed, preformed seasonal growth to more flexible, ongoing organ production—to predict how species will differ in risk exposure ...
