Fisheries and Oceans, Canada, 50th Ave. Bering 20, Anadyr,Russia. Their matrilineal structure has strongly influenced the thinking about social structure in less well-studied cetaceans, including beluga whales.
In a cross-sectional study of group structure and kinship we found that belugas formed a limited of distinct group types, consistently observed across populations and habitats. Certain behaviours were associated with group type, but group membership was often dynamic.
MtDNA-microsatellite profiling combined with relatedness and network analysis revealed, contrary to predictions, Strapon sex Campo grande most social groupings were not predominantly organized around close maternal relatives.
They comprised both kin and non-kin, many group members were paternal rather than maternal relatives, and unrelated adult males often traveled.

The evolutionary mechanisms that shape beluga societies are likely complex; fitness benefits may be achieved through reciprocity, mutualism and kin selection. At the largest scales these societies are communities comprising all ages and both sexes where multiple Amateur swingers Henderson learning pathways involving kin and non-kin can foster the emergence of cultures.
We explore the implications of these findings for species management and the evolution of menopause. Free Single Jacksonville lady truckers text Read article at publisher's site DOI : Impact metrics.
