Decline and fall: The causes of group failure in cooperatively breeding meerkats
Ecology and Evolution, 2021 In many social vertebrates, variation in group persistence exerts an important effect on individual fitness and population demography. However, few studies have been able to investigate the failure of groups or the causes of the variation in their ...

Social brain hypothesis, vocal and gesture networks of wild chimpanzees
Frontiers in Psychology, 2016 A key driver of brain evolution in primates and humans is the cognitive demands arising from managing social relationships. In primates, grooming plays a key role in maintaining these relationships, but the time that can be devoted to grooming is ...

Frontiers in Ecology and Evolution, 2022 Explaining why animal groups vary in size is a fundamental problem in behavioral ecology. One hypothesis is that life-history differences among individuals lead to sorting of phenotypes into groups of different sizes where each individual does best. This

Speakers are more cooperative and less individual when interacting in larger group sizes
Frontiers in Psychology, 2023 IntroductionCooperation, acoustically signaled through vocal convergence, is facilitated when group members are more similar. Excessive vocal convergence may, however, weaken individual recognizability.

Multiple Sentinels in a Cooperative Breeder Synchronize Rather Than Coordinate Gazing
Animals, 2023 Sentinels can detect predators and rivals early by monitoring their surroundings from vantage points. Multiple sentinels in a group may reduce the perceived predation risk by diluting the risk and increasing collective detection, especially if sentinels ...

Vigilance responding to number of conspecifics among mixed groups of cranes in demilitarized zone
Animal Cells and Systems, 2018 Numerous studies have addressed antipredatory benefits of mixed-species flocks of foragers, but studies on individual's vigilance as a function of group size are limited. In the Cheolwon area of the Korean Demilitarized Zone, vigilance of the subordinate
