“…The influence of inclusive fitness on affiliative behaviour has been extensively studied in species ranging from eusocial insects (Reeve et al, 1990, Seger, 1991and Bourke, 1997 to long-lived mammals such as primates (Chapais, 2001, Clutton-Brock, 2002, Perry et al, 2008and Langergraber et al, 2009, lions, Panthera leo (Packer et al 1991), elephants ( Fernando andLande, 2000 andArchie et al, 2006) and cetaceans ( Whitehead and Baird, 2000, Krützen et al, 2003, Parsons et al, 2003and Gero et al, 2009). Owing to practical difficulties in data collection, however, few studies of kinship in mammalian societies have been able to consider the complex interactions between home range overlap, association patterns and kinship (Maher 2009).…”

Few studies of kinship in mammalian societies have been able to consider the complex interactions between home range overlap, association patterns and kinship, which have created a critical gap in our understanding of social evolution. We investigated the association patterns of female bottlenose dolphins, Tursiops aduncus, in the eastern gulf of Shark Bay, Western Australia and found that they depended upon the complex interplay of at least three factors: home range overlap, matrilineal kinship and biparental kinship. While home range overlap was positively correlated with female association patterns, preferred associations were found between females showing as little as 27% home range overlap, and some pairs showed avoidance despite 100% home range overlap. Furthermore, on average, both casual and preferred associations took place between females that were more closely biparentally related than expected by chance and this pattern varied depending upon whether or not pairs of females shared the same matriline.

“…Kin-structured social groups have previously been documented for a range of taxa (Parsons et al 2003, Fraser et al 2005. However, as far as we know, the question of whether sharks avoid or preferentially associate with kin has been completely unexplored.…”

For marine predators there is a paucity of studies on social behaviour, and even fewer studies have quantified interactions between individuals. In the present study, we looked at the social structure and leadership of free-ranging juvenile lemon shark Negaprion brevirostris in a known aggregation site, Bimini, the Bahamas. Observations of these sharks were made from towers placed in a mangrove inlet, where clear, shallow, protected waters made it possible to record group compositions of externally colour-code tagged wild juvenile lemon sharks. Thirty-eight different individual sharks were observed to use the area over a 2 yr period. Results show repeated social interactions suggestive of active partner preference. In addition, we found that group structure was mostly explained by body length, and possibly by preference for relatives but not by sex. Finally, we observed that some sharks led more groups than others and that those lead individuals were usually larger than those following them. This study quantifies the social structure of a free-ranging shark population and provides novel insights into the social behaviour of juvenile sharks.

“…Likewise, genetic relatedness only explained associations within the SCR community. Kinbased and overlapping associations have been recorded in some bottlenose dolphin populations (Parsons et al, 2003;, but not in others (Möller, 2001). It would therefore appear that other intrinsic or extrinsic factors are likely to drive the social patterns within each community.…”
