Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.
