Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 783-791, May 2026.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

From species lists to interactions: Network structure, not richness, guides seed dispersal management in human‐modified islands

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings show that management strategies can create fundamentally different seed dispersal regimes, even under similar environmental conditions. Anthropogenic diversification reshapes network organisation into distinct structural configurations, rather than consistently enhancing overall cohesion.

Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...
