This comprehensive introductory text integrates evolutionary, ecological, and demographic
perspectives with new results from field studies and contemporary noninvasive molecular …

Passive acoustic monitoring (PAM) has the potential to greatly improve our ability to monitor
cryptic yet vocal animals. Advances in automated signal detection have increased the scope …

The rarity of female-biased kinship organization in human societies raises questions about
ancestral hominin family structures. Such questions require grounding in the form and …

Gibbons are generally reported to live in small socially monogamous family groups in which
both sexes disperse when they reach maturity. For the first time, we documented the …

Herpes B virus (BV) is a zoonotic virus which can be transmitted from macaques to humans,
which is often associated with high mortality rates. Because macaques often exhibit …

Decades of research have led to a solid understanding of the social systems of gregarious
apes: chimpanzees, bonobos, gorillas, and gibbons. As field studies have increasingly …

White-handed gibbons produce loud and acoustically complex songs when interacting with
their neighbours or when encountering predators. In both contexts, songs are assembled …

Loud calls play an important function in regulating the use of space and structuring social
groups and mating systems in a wide range of taxa. In pair‐living territorial animals, where …

Many animals rely on acoustic signals to mediate social interactions with conspecifics. Duets–
–the alternating vocal exchange between two animals––are of particular interest given the …

All gibbon species are declining throughout South and South-east Asia because of habitat
loss and human activities such as hunting. Lao still contains a relatively large area of forest …
