Bees are particularly affected by higher temperatures and more intensive land use, new study reveals
- Researchers at Julius-Maximilians-Universitt Wrzburg published a 2025 study revealing how warmer temperatures and land use affect bees across 179 Bavarian sites.
- The study arose from concerns about global insect declines driven by climate warming, habitat loss, and their interactive effects on food webs and ecosystem services.
- Bees, mainly diurnal insects, respond negatively to higher night temperatures by reduced richness across all habitats, while warmer days increased bee numbers only in forests and grasslands.
- The research found urban bee populations declined by 65%, highlighting the impact of heat combined with intensive land use, with Dr. Cristina Ganuza noting the importance of physiological stresses during rest periods.
- These findings imply that protecting heterogeneous landscapes is vital for preserving pollination and pest control, and underscore an urgent need for tailored research and policies to address insect declines.

The Bees Are Vanishing Again and It’s Worse Than Ever - One Green Planet
Honeybees are vanishing again, and this time it’s worse — a perfect storm of policy, pesticides, and parasites is decimating colonies. The post The Bees Are Vanishing Again and It’s Worse Than Ever appeared first on One Green Planet.
Bees are particularly affected by higher temperatures and more intensive land use, new study reveals
The number and diversity of insects is declining worldwide. Some studies suggest that their biomass has almost halved since the 1970s. Among the main reasons for this are habitat loss—for example through agriculture or urbanization—and climate change.
