Discrimination of Acoustic Stimuli and Maintenance of Graded Alarm Call Structure in Captive Meerkats
Animals living in human care for several generations face the risk of losing natural behaviors, which can lead to reduced animal welfare. The goal of this study is to demonstrate that meerkats (Suricata suricatta) living in zoos can assess potential danger and respond naturally based on acoustic signals only. This includes that the graded information […]
Participation in group defence: proximate factors affecting male behaviour in wild white-faced capuchins
When two social groups of the same species confront each other, what factors influence whether individuals participate in the struggle for defence of their group and its resources? In white-faced capuchin monkeys, Cebus capucinus, adult males play an important role in the outcome of intergroup encounters by cooperating aggressively against their opponents. However, not all […]
Mother–offspring recognition in the bat Carollia perspicillata
Parental care is crucial for offspring survival in many taxa but its burden and costs are often not equally distributed between the sexes. In bats, the majority of parental care is provided by females, making examples of paternal support towards pups exceedingly rare. One exception to this general pattern seemed to be the polygynous Seba’s […]
