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

open access: yesJournal 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.

Reintroduction affects demographic rates but not their interannual correlations in an endangered shrub

open access: yesJournal of Applied Ecology, Volume 61, Issue 12, Page 3040-3052, December 2024.
Our study shows that stressful conditions may trigger individual‐level trade‐offs in resource allocation and population‐level compensation among demographic rates. Demographic shifts arising from reintroductions in different environmental conditions may be considered by managers as a potential mechanism of resilience against environmental change ...

Thermal plasticity has higher fitness costs among thermally tolerant genotypes of Tigriopus californicus

open access: yesFunctional Ecology, Volume 38, Issue 7, Page 1562-1577, July 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Under climate change, ectotherms will likely face pressure to adapt to novel thermal environments by increasing their upper thermal tolerance and its plasticity, a measure of thermal acclimation. Ectotherm populations with high thermal tolerance are often less thermally
