Association networks reveal social organization in the sleepy lizard
We investigated the social organization of the Australian sleepy lizard, Tiliqua rugosa, by describing the social network of a local population. We attached activity meters and GPS recorders to 21 neighbouring lizards in a semiarid site in South Australia, and monitored their location every 10 min over 3 months (September-December 2007). From over 5000 sets of […]
Non-Monogamous Copulations and Potential Within-Group Mating Competition in White-Faced Saki Monkeys (Pithecia pithecia)
Many primates display within-species variation in social organization and mating system. Individuals of these species may be confronted with both the challenges of between-group competition to exclude same-sex competitors as well as within-group competition for mating opportunities. Free-ranging white-faced saki monkeys (Pithecia pithecia) live in both male–female pairs and small multi-male, multi-female groups. Despite commonly […]
Extra-pair paternity confirmed in wild white-handed gibbons
Knowledge of the genetic mating system of animal species is essential for our understanding of the evolution of social systems and individual reproductive strategies. In recent years, genetic methods have uncovered an unexpected diversity of paternal genetic contributions across diverse animal social mating systems, but particularly in pair-living species. In most pair-living birds, for example, […]
