ABSTRACT Fire is a major form of environmental disturbance, and in recent years, due to anthropogenic climate change and anthropogenic land management, we are seeing increases in the frequency and intensity of fires. With bees being an important, diverse group of pollinators that is facing declines globally, understanding how they respond to fires is ...

Bumblebees are the most efficient pollinators of raspberry and strawberry in urban environments
We evaluated single‐visit pollination efficiency, on strawberry and raspberry plants, in urban and suburban sites. Bumblebees were overall the most efficient pollinator. For strawberry, bumblebees had equivalent efficiency to honeybees, while for raspberry, bumblebees were more efficient than honeybees.

The study demonstrates that sufficient B supply is crucial for successful rapeseed flower growth and fertility as well as for attracting pollinating insects, thus securing yield in a pollinator‐dependent crop. It is illustrated that climate change can pose a threat to crop yield via both direct effects, that is, an impaired nutrient uptake, and ...
