Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Tree species identity shapes the relationship between canopy cover and herb‐layer species in temperate forests

open access: yesJournal of Ecology, Volume 113, Issue 3, Page 582-597, March 2025.
This study is an empirical demonstration of the importance of tree species identity cover in shaping the distribution of the herb layer, surpassing the effects of tree diversity alone. By considering the significance of tree species identity cover, we can inform forest management and conservation measures, improve spatial prediction of herb‐layer ...

Towards a global understanding of tree mortality

open access: yesNew Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Wave dissipation by flexible vegetation [PDF]

open access: yes, 2011
Dissipation of waves propagating through natural salt marsh vegetation was about half the dissipation expected for rigid vegetation. This low dissipation was predicted by a theoretical model that accounts for bending of vegetation by wave motions.
