Biological collectives, like honeybee colonies, can make intelligent decisions and robustly adapt to changing conditions via intricate systems of excitatory inhibitory signals. In this study, we explore the role behavioural plasticity its relationship network size by manipulating colony exposure an artificial signal. As predicted, inhibition was strongest in large colonies weakest small colonies. This is ecologically relevant for honeybees, which reduced effects may increase robustness that...
Honey bee defensive behaviors are crucial for countering new predators such as invasive German yellowjackets (Vespula germanica). We provide the first data on ability of scutellata-hybrids (Africanized bees) to defend their colonies against V. germanica wasps, compared European honey bees. The scutellata-hybrid recruited twice many defender bees in defense, and killed three times more often than managed colonies. hybrids threats is intriguing suggests that research should be conducted into...
