The duration of high spring light for understorey plants: Contrasting responses to spatial and temporal temperature variation

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2526-2538, September 2025.
Over 7 years, warmer springs were associated with earlier leaf‐out of two temperate forest understorey herbs and of the trees above them, but the effect was stronger for the herbs. This suggests that climate warming will prolong the relatively brief period of high light available to understorey plants in spring, which is a key determinant of their ...

Improving the Monitoring of the Invasive Blue Crab (Callinectes sapidus): Combining Environmental DNA and Citizen Observations

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Early detection is a crucial tool for identifying the spread of invasive species. In this study, we validated a probe‐based quantitative polymerase chain reaction (qPCR) assay for the detection of the invasive Blue Crab, Callinectes sapidus, in the Mediterranean Sea, using 22 initial eDNA environmental samples (eDNA) collected from three ...

Animal movement in space and time: the role of thermal barriers and individual variation in modulating predator–prey overlap in stratified lakes

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Animal movements play a crucial role in ecosystem dynamics, regulating numerous functions from nutrient cycling to habitat coupling. Therefore, any factor modulating animal behavior (e.g. physiology and individual preferences in habitat choice) has the potential to influence ecosystem functioning.

Vegetation and channel adjustment trajectories in cold regions: The effects of ice disturbances in two Gaspesian rivers

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This study explores the role of ice jam regimes on the biogeomorphological dynamics of two cold‐climate rivers. The analysis of vegetation and channel planform adjustments on a 60‐year timescale showed that the ice jam regime had notable impacts on vegetation successional dynamics, which further modulate geomorphological changes.
