Behavioural flexibility masks delayed costs of environmental instability

This study shows that environmental instability affects bumblebee foraging behavior over time, with delayed costs not captured by immediate performance measures.

Warming limits energetic investment in feeding and post-feeding metabolism in bumblebees

This study shows that warming reduces thermogenic investment and postprandial metabolic responses in bumblebees, limiting their energetic flexibility under climate change.

First direct quantification of floral handling costs in bees

The paper quantifies the metabolic cost of floral buzzing in bumblebees and shows it is energetically significant, comparable to flight take-off.

Male bumblebees adapt foraging to environmental conditions to sustain mate-seeking efforts

This study shows male bumblebees adjust foraging behavior to maintain reproductive efforts despite environmental challenges.
