Association patterns of bottlenose dolphins (Tursiops truncatus) in Bahía San Antonio, Argentina

摘要: This study aims to investigate the association patterns of a small and resident population bottlenose dolphins (Tursiops truncatus) in Bahia San Antonio (Argentina), assess any seasonal variation view reported population's grouping behavior. The estimation social differentiation (S) was 0.29 (SE = 0.08), suggesting homogenous society. half-weight index (HWI) averaged 0.23 (± 0.06), with evidence long-term preferred associations. However, data showed patterns. In winter, when large groups were this population, HWI values 0.30 0.09) no indication or avoided during summer, group size generally small, 0.14 0.07), an preferred/avoided indicates that structure seems relatively flexible over time, formation random network at times aggregations are formed, more disconnected made up strongly connected components cost is high.
