Scientists in Germany have observed nematode worms forming cooperative 'superorganisms' by creating towering structures in the wild, a behavior previously only seen in labs, revealing new insights into their social interactions and group movement strategies.
Researchers from Michigan State University have found that social relationships and interactions among spotted hyenas can influence their decision to form mobs and cooperate in attacking lions. The study, conducted over 35 years, revealed that hyenas with strong social bonds are more likely to engage in mobbing behavior. This cooperative behavior sheds light on how similar behaviors have evolved in both wildlife and humans. The researchers also discovered that mobbing was more frequent when the risk of injury or death to hyenas was lower, even in the absence of a direct benefit.
A study on spotted hyenas in the wild has shed light on the factors that determine whether individuals will engage in risky collective activities, such as mobbing behavior to drive away lions. This cooperative behavior involves a trade-off between risks and rewards, providing access to carcasses that have been killed by lions or hyenas.
Researchers at the Weizmann Institute of Science have discovered that when ants of the species Paratrechina longicornis collectively carry a large object, their behavior mimics that of a self-propelled particle moving through a fluid. The ants create a trail of pheromones to seek assistance, with ants in front pulling and those in the back pushing and lifting to reduce friction. The study suggests that the behavior of a self-propelled particle could serve as a model for understanding systems of interacting individuals.
