From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog.

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

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.
