Historical and recent investigations on the bee fauna of Taiwan (Hymenoptera, Apoidea) [PDF]
The bee fauna of Taiwan was studied intensively in the first half of last century and was based in large parts on the extensive material collected by Hans Sauter between 1902 and 1914. Subsequent studies on bees of Taiwan have only been sporadic.

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.
