Rival group scent induces changes in dwarf mongoose immediate behaviour and subsequent movement [PDF]
, 2016 In many social species, groups of animals defend a shared territory against rival conspecifics. Intruders can be detected from a variety of cues, including faecal deposits, and the strength of response is expected to vary depending on the identity of the

Abduction and potential case of predation of an infant howler monkey (Alouatta guariba clamitans) by a tufted capuchin monkey (Sapajus nigritus) [PDF]
, 2017 The likelihood of interspecific interactions between wild primates is particularly high for species with overlapping territories. The sharing of the same or similar ecological niches can result in competition for space or resources, which can lead to ...

Traditions in spider monkeys are biased towards the social domain [PDF]
, 2011 Cross-site comparison studies of behavioral variation can provide evidence for traditions in wild species once ecological and genetic factors are excluded as causes for cross-site differences.

A model for within-group coalitionary aggression among males [PDF]
, 2018 Perhaps the most common form of cooperation among primates is the formation of coalitions. Competition among males within a group concerns a constant quantity of the limiting resource (fertilizations).

Watch out or relax: conspecifics affect vigilance in wild spider monkeys (Ateles geoffroyi) [PDF]
In most animal species, predation risk is considered the main factor affecting vigilance, and an individual is expected to spend less time vigilant in larger than in smaller groups.

Hyperostotic tympanic bone spicules in domestic and wild animal species [PDF]
, 2016 Hyperostotic tympanic bone spicules (HTBS), or "mucoperiosteal exostoses" (ME, syn.) are small, globular (>= 1 mm in diameter), mostly stalked and drumstick-like, bony structures, which arise from the inner wall of the tympanic bulla and project into the

Chimpanzee hunting behavior [PDF]
, 2007 The pursuit, capture and consumption of small-and medium-sized vertebrates, appears to be typical of all chimpanzee (Pan troglodytes) populations, although large variation exists. Red colobus monkeys (Piliocolobus sp.) appear to be the preferred prey but

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.
