Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

New Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

Climatic disequilibrium modulates canopy service across abiotic stress gradients

Journal of Ecology, Volume 113, Issue 8, Page 2160-2172, August 2025.
The results presented indicate that abiotic stressors, combined with climatic disequilibrium, modulate the canopy service. Consequently, under future climate change scenarios that may increase stress and climatic disequilibrium, canopy service will become crucial for the maintenance of the recruiting community.

Conservation‐focused mapping of avian migratory routes using a pan‐European automated telemetry network

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Accelerated biodiversity loss has destabilized functional links within and between ecosystems. Species that cross different ecosystems during migration between breeding and nonbreeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem‐specific, threats.

The interplay between virus infection and water‐related stress is mediated by the plant metabolism of ascorbic acid

New Phytologist, Volume 247, Issue 1, Page 265-280, July 2025.
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection

Lessons to learn from pilot studies in clinical trials: The example of a trauma‐focused treatment for female survivors of intimate partner violence

Counselling and Psychotherapy Research, Volume 25, Issue 2, June 2025.
Abstract Background Research on pilot studies is scarce, despite their importance for the development of effective clinical trials. There is a lack of work addressing the process, limitations and strategies derived from these studies. This gap is even more evident in research studying targeted populations, such as victims of intimate partner violence ...

Metabolic traits and thresholds to inform marine ecological conservation and restoration

Journal of Applied Ecology, Volume 62, Issue 6, Page 1350-1363, June 2025.
Integrating organismal responses to environmental stressors into monitoring protocols can provide early warning indicators of ecosystem health. This approach strengthens conservation and restoration initiatives, supporting policy decisions in the face of increasing coastal development and climate change.
