Colony-level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation.

Leeah I. Richardson, Olivia Miller, David Sossa…·Heather L. Grab

The paper assesses how landscape composition affects foraging behavior and pollination of managed bumble bees in strawberry fields, finding that colonies collect more rosaceous pollen in areas with larger strawberry fields.

Climate-driven specialisation in plant-pollinator networks peaks outside the tropics

Sailee P. Sakhalkar, Nico Blüthgen, Laura A. Burkle…·Jan E. J. Mertens

The paper shows climate, not latitude, drives plant-pollinator specialisation globally, with specialisation peaking at northern mid-latitudes and declining in warmer, more seasonal climates.
