Species richness patterns in Fijian bees are explained by constraints in physiological traits

This study shows that physiological traits like heat tolerance and desiccation resistance constrain bee species richness in Fijian elevational gradients, with species tracking climatic niches to higher elevations as climates warm.

Physiological traits and their relationships vary along an elevational gradient within and among Fijian bee species

This study examines how metabolic rates and gas exchange patterns vary with elevation in Fijian bees, finding support for the metabolic cold adaptation hypothesis but not the hygric hypothesis.

A common venomous ancestor? Prevalent bee venom genes evolved before the aculeate stinger while few major toxins are bee-specific

The paper investigates the origin of venom genes in hymenopteran insects, finding that most venom proteins predate the evolution of the aculeate stinger and are shared across the clade, with only a few being unique to bees.

Multiple parasitism promotes facultative host acceptance of cuckoo eggs and rejection of cuckoo chicks

The paper tests the clutch dilution hypothesis in gerygones, finding higher egg survival when they accept cuckoo eggs, but also flexibility in rejecting them when clutches contain only cuckoo eggs.

Stingless bee floral visitation in the global tropics and subtropics

This paper reviews global stingless bee floral visitation, compiling data on plant families visited and highlighting regional differences and gaps in knowledge.

Irreversible sterility of workers and high-volume egg production by queens in the stingless bee Tetragonula carbonaria

This study shows that workers in the stingless bee Tetragonula carbonaria are irreversibly sterile and cannot activate their ovaries even when isolated from queens and fed royal jelly.

Tests of hybridisation in Tetragonula stingless bees using multiple genetic markers.

The paper re-examines hybridisation in three Tetragonula stingless bee species using multiple genetic markers and finds no evidence of ongoing gene flow.
