The payoffs and tradeoffs of hygienic behavior: A large-scale field study on a local population of honey bees

This study evaluates hygienic behavior in honey bees to reduce Varroa infestation, finding it heritable and beneficial without major trade-offs.

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.

Incipient species or social polymorphism? Diversity in the desert ant Cataglyphis

The paper investigates whether distinct mitochondrial DNA lineages in desert ants are incipient species or social polymorphism within a single species.

Demography and behaviour of polygyne nests of the supercolonial ant Cataglyphis niger: Does kinship matter?

The paper investigates social interactions in polygyne nests of Cataglyphis niger, showing that queens and workers are not necessarily related and workers contribute equally to queen rearing.

Chemical signatures of honey bee group membership develop via a socially-modulated innate process

This study shows that honey bee nestmate recognition cues develop through age-dependent chemical transitions driven by innate pathways and modulated by social factors, not via a passive homogenization process.
