Agonistic Interactions of Juvenile Savanna Baboons: II. Agonistic Support and Rank Acquisition
19 juvenile members of known genealogies in two wild baboon groups were studied over a 16month period. Males and females in two age classes were compared regarding third-party aggression and support given and received during agonistic interaction. Young juvenile males and females (1-2.5 years-old) were supported predominantly by their probable fathers. The adult males supported without regard t...
متن کاملSignal Use by Octopuses in Agonistic Interactions
Cephalopods show behavioral parallels to birds and mammals despite considerable evolutionary distance [1, 2]. Many cephalopods produce complex body patterns and visual signals, documented especially in cuttlefish and squid, where they are used both in camouflage and a range of interspecific interactions [1, 3-5]. Octopuses, in contrast, are usually seen as solitary and asocial [6, 7]; their bod...
متن کاملCorrelates of Agonistic and Competitive Interactions in Pregnant Baboons
Maternal condition during pregnancy is known to influence fetal viability. Recently, primatologists have suggested that certain characteristics of the fetus may influence maternal condition as well. For example, among captive pigtailed macaques (Macaca nemestrina) mothers of female infants may be a t greater risk of injury during their pregnancies than mothers of male infants. Analysis of the r...
متن کاملAppraisal of unimodal cues during agonistic interactions in Maylandia zebra
Communication is essential during social interactions including animal conflicts and it is often a complex process involving multiple sensory channels or modalities. To better understand how different modalities interact during communication, it is fundamental to study the behavioural responses to both the composite multimodal signal and each unimodal component with adequate experimental protoc...
متن کاملDeterminants of agonistic interactions in California sea lions
California sea lions aggregate in high density colonies during the breeding season. Competition for space and mates results in agonistic interactions that may have long-term population consequences. We explored how demographic, behavioral, and environmental variables influence the rate of agonistic interactions in male and female California sea lions at three breeding colonies with varying popu...
