Towards one third extinction
One bee, Two bee, Oh!
There are 260 known species of bumblebees globally many of which are important pollinators, particularly in agriculture. A phylogenetic study of ~43% of these species has revealed that approximately one third of the species are declining. The Thoracobombus subgenus which accounts for 64% of species tested is particularly vulnerable, as are species of bumblebee with small geographic ranges. Arbetman et al, 2017.
