Mitochondrial evidence for multiple radiations in the evolutionary history of small apes
BackgroundGibbons or small apes inhabit tropical and subtropical rain forests in Southeast Asia and adjacent regions, and are, next to great apes, our closest living relatives. With up to 16 species,Expand

Social Tolerance in Wild Female Crested Macaques (Macaca nigra) in Tangkoko-Batuangus Nature Reserve, Sulawesi, Indonesia
In primates, females typically drive the evolution of the social system and present a wide diversity of social structures. To understand this diversity, it is necessary to document the consistencyExpand

Personality of Wild Male Crested Macaques (Macaca nigra)
Animal personalities, i.e. consistent differences in behavior across time and/or context, have received increased attention of behavioral biologists over the last years. Recent research shows thatExpand

Sexual signalling in female crested macaques and the evolution of primate fertility signals
BackgroundFemale signals of fertility have evolved in diverse taxa. Among the most interesting study systems are those of multimale multifemale group-living primates, where females signal fertilityExpand

Multicomponent and Multimodal Lipsmacking in Crested Macaques (Macaca nigra)
TLDR
We show that lipsmacks composed of both visual and vocal components (i.e. multimodal signals) increased the probability of affiliative contact, and therefore have enhanced signal value. Expand

Social bonds affect anti-predator behaviour in a tolerant species of macaque, Macaca nigra
Enduring positive social bonds between individuals are crucial for humans' health and well being. Similar bonds can be found in a wide range of taxa, revealing the evolutionary origins of humans'Expand

Androgen correlates of male reproductive effort in wild male long-tailed macaques (Macaca fascicularis): A multi-level test of the challenge hypothesis
The challenge hypothesis (Wingfield et al., 1990) has been broadly utilised as a conceptual framework to study male androgen correlates of reproductive challenges in mammals. These studies mainlyExpand

Costs of and Investment in Mate-Guarding in Wild Long-Tailed Macaques (Macaca fascicularis): Influences of Female Characteristics and Male–Female Social Bonds
Male primates living in multimale groups tend to direct mate and mate-guarding choices toward females of high reproductive value, i.e., high-ranking, parous females, or females with which they shareExpand

Is social dispersal stressful? A study in male crested macaques (Macaca nigra)
&NA; In gregarious species, dispersal events represent one of the most dramatic changes in social life and environment an animal will experience during life due to increased predation risk,Expand

Costs of mate-guarding in wild male long-tailed macaques (Macaca fascicularis): Physiological stress and aggression
Mate-guarding is an important determinant of male reproductive success in a number of species. However, it is known to potentially incur costs. The aim of the present study was to assess the effectExpand
