Like bees, ants organize their colonies based on social rank. It appears trap-jaw ants engage in antenna-boxing matches to dictate who guards the colony and who goes out into the world to forage.
Japanese macaques are exposed to various stressful situations in the wild, including rank fights and mating competitions. Researchers recently took a closer look at how genetics ultimately control the release of stress hormones in these animals.
Monk parakeets fight each other systematically for social rankings within new groups. After a week of aggressive interactions, the birds quickly learn who falls where in the hierarchy.
It seems that even baboons form their own cliques, but new research shows that this can limit learning among the group.
Higher social status has its perks, and new research shows that one of them is a healthier life... as least for wild animals.
Kids teasing, taunting and bullying one another on the playground is nothing out of the ordinary, and the same goes for chimpanzees. And if any of these antics were to result in a confrontation, new research shows that those chimps with macho moms are more likely to win the fight.
