dolphins_caravelas — Guiana dolphin social network (2012)

Description

Weighted social network of a population of Guiana dolphins (Sotalia guianensis) in the Caravelas River estuary, Bahia, Brazil, from the study of M. Cantor and collaborators on the temporal structure of this dolphin society. The data were compiled by M. Cantor and collaborators for a study of nestedness across levels of biological organization, and are distributed in the repository of that study (file pop_sotalia.txt). Individuals were identified by photo-identification of natural markings on the dorsal fin, and two individuals were considered associated when observed in the same group. Nodes are individuals, and an undirected edge connects two individuals that were observed together at least once, weighted by their association index, the half-weight index (HWI), an estimate of the proportion of time the two individuals spend together (from 0, never seen together, to 1, always together). Only the 33 individuals that were seen in the study area more than three times during the study period are included. The individuals are not identified in the source data.

The edges have the property weight, the half-weight association index.
