In: Behaviour

individuals may arise from male sex-biased dispersal rather than from active kin preferences based on kin discrimination. Keywords : kin recognition, Lacerta vivipara , relatedness, spacing structure. Introduction Besides competition, inbreeding avoidance (re- viewed in Johnson and Gaines, 1990) and habi- tat

réponse aux mêmes conditions actuelles qui sont qualitativement semblables mais intrinsèquement différents. Keywords : kin preferences, grooming networks, time constraints, phylogenetic model, ma- caques. Introduction The preferential treatment of kin (kin bias) is widespread among group liv- ing species

In: Behaviour

correlation was unsustained when group size was con- trolled. We suggest that kin-focused grooming networks are shaped at least in part by time constraints and may not be linked directly or indirectly to within-group competition. Keywords : kin preferences, grooming networks, time constraints, within

most males disperse from their natal groups at sexual maturity. Early research focused primarily on two species, the Japanese ( M. fuscata ) and rhesus macaques ( M. mulatta ), shaped what came to be considered the norm for macaque societies: strong kin preferences, intense unidirectional aggression

In: Behaviour

scenarios and genetic models have been developed from the roles of different cue sources observed in studies of different species. Discrimination may also occur within colonies containing more than one genetic line, though the kin preferences reported in this context have been weaker than expected. However
