Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity

Global Change Biology, Volume 32, Issue 6, June 2026.
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

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.
