The influence of the social environment on larval development and resulting caste in Bombus impatiens

This study examines how the social environment affects larval development and caste in Bombus impatiens, finding that body size and caste are influenced by the number of caretakers, not queen presence.

Gyne production is regulated by the brood in a social bee (Bombus impatiens)

This study shows that brood size in Bombus impatiens colonies significantly increases gyne production, while worker ovary activation is influenced by both brood presence and colony size.

Impacts and mechanisms of CO2 narcosis in bumble bees: Narcosis depends on dose, caste and mating status and is not induced by anoxia

This study investigates CO2 narcosis in bumble bees, finding it depends on dose, caste, and mating status, and is not caused by anoxia.

Built to change: dominance strategy changes with life stage in a primitively eusocial bee

This study shows that queen bees shift from aggressive to chemical signaling as they age to maintain reproductive dominance in their colony.

Dufour's gland analysis reveals caste and physiology specific signals in Bombus impatiens

The paper analyzes Dufour's gland secretions in Bombus impatiens to identify caste- and physiology-specific chemical signals and their behavioral impacts.

High thermal plasticity and vulnerability in extreme environments at the warm distributional edge: the case of a tidepool shrimp

This study assesses the thermal vulnerability of tidepool shrimp at their warm distributional edge, finding limited warming tolerance and reduced performance under extreme temperatures.

Shift in worker physiology and gene expression pattern from reproductive to diapause-like with colony age in the bumble bee Bombus impatiens

This study shows that bumble bee workers shift from reproductive-like to diapause-like physiology and gene expression as the colony ages.

A small family business: synergistic and additive effects of the queen and the brood on worker reproduction in a primitively eusocial bee

This study investigates how the queen and brood regulate worker reproduction in primitively eusocial bees, finding synergistic and additive interactions in their effects on physiology and behavior.
