Possible male infanticide in wild orangutans and a re-evaluation of infanticide risk [PDF]
, 2019 Infanticide as a male reproductive tactic is widespread across mammals, and is particularly prevalent in catarrhine primates. While it has never been observed in wild orangutans, infanticide by non-sire males has been predicted to occur due to their ...

Why are male social relationships complex in the Doubtful Sound bottlenose dolphin population?
PLoS ONE, 2007 BackgroundAccess to oestrus females tends to be the main driver of male sociality. This factor can lead to complex behavioural interactions between males and groups of males.

Wild chimpanzees' use of single and combined vocal and gestural signals [PDF]
, 2017 We describe the individual and combined use of vocalizations and gestures in wild chimpanzees. The rate of gesturing peaked in infancy and, with the exception of the alpha male, decreased again in older age groups, while vocal signals showed the opposite

No Evidence of Short-Term Exchange of Meat for Sex among Chimpanzees [PDF]
, 2011 The meat-for-sex hypothesis posits that male chimpanzees (Pan troglodytes) trade meat with estrous females in exchange for short-term mating access. This notion is widely cited in the anthropological literature and has been used to construct scenarios ...

No short-term contingency between grooming and food tolerance in Barbary macaques (Macaca sylvanus) [PDF]
, 2015 The exchange services such as allo-grooming, allo-preening, food tolerance and agonistic support has been observed in a range of species. Two proximate mechanisms have been proposed to explain the exchanges of services in animals.

Effect of artificial warren size on a restocked European wild rabbit population [PDF]
, 2017 From the time since the decline of the wild rabbit Oryctolagus cuniculus in southern Europe, various techniques and methods have been explored with a view to restoring wild rabbit populations or increasing rabbit resilience, for both conservation and ...

Testing the reproductive and somatic trade‐off in female Columbian ground squirrels
Ecology and Evolution, Volume 6, Issue 21, Page 7586-7595, November 2016., 2016 Energetic trade‐offs in resource allocation form the basis of life‐history theory, which predicts that reproductive allocation in a given season, should negatively affect future reproduction or individual survival. We examined how allocations of resources differed between successful and unsuccessful breeding female Columbian ground squirrels to discern

Sex-specific reproductive behaviours and paternity in free-ranging Barbary macaques (Macaca sylvanus) [PDF]
In a wide variety of species, male reproductive success is determined by contest for access to females. Among multi-male primate groups, however, factors in addition to male competitive ability may also influence paternity outcome, although their exact ...

Habitat Selection and Mating Success in a Mustelid
International Journal of Zoology, Volume 2011, Issue 1, 2011., 2011 Habitat selection remains a poorly understood ecological process, but relating mating behaviour to pattern of habitat selection constitutes a fundamental issue both in evolutionary ecology and in biological conservation. From radiotelemetry protocol, habitat‐induced variations in mating success were investigated in a solitary mustelid carnivore, the ...
