Immune defence in bumble-bee offspring
Nature, 2001Immune-challenged vertebrate females transfer specific antibodies to their offspring, but this gratuitous immunity cannot operate in invertebrates. Here we show that constitutive immune defence is enhanced in sexual offspring of the bumble-bee Bombus terrestris L. when the parental colony is immune-challenged.

ALIEN BUMBLE BEE AFFECTS NATIVE PLANT REPRODUCTION THROUGH INTERACTIONS WITH NATIVE BUMBLE BEES
Ecology, 2008The invasive alien bumble bee Bombus terrestris may hinder the reproduction of native plants that have established specialized pollination systems with native bumble bees. To test this hypothesis, we examined the visitation frequency and behavior of native and alien bumble bee species and resultant seed production in Corydalis ambigua, a native plant ...

Positive affective contagion in bumble bees
ScienceAffective contagion, a core component of empathy, has been widely characterized in social vertebrates but its existence in any invertebrate is unknown. Using a cognitive bias paradigm we demonstrate positive affective contagion in bumble bees. After being trained on colored flowers with different reinforcements, bees that interacted with a conspecific ...
