From: The ability of artisanal fishers to recognize the dolphins they cooperate with
Variation in the ability in recognize individual dolphins, concordance, and consensus among artisanal fishers across a set of explanatory variables. Recognition index (RI) does not change significantly with dolphin home range (a), dolphin encounter rate (b), dolphin behavior (“good” or “bad” dolphin; c); but the index increases when dolphins are recognized by marks in the dorsal fin in comparison to body shape and general behavior (form) (d). The Concordance index (CDI) does not change with dolphin home range (e) and encounter rate (f), dolphin behavior (“good” or “bad” dolphin; g); but it increases when dolphins are recognized by marks in the dorsal fin (h). The average consensus (ACI) do not vary with fishers’ age (i) and preferable fishing site (j); it is significantly higher when fishers learn how to fishing with dolphins from parents or other relatives (families) (l) and it increases slightly whether they depend on this fishing activity (m); the consensus in naming dolphins (CeIc) does not change significantly with the perceived age (n), sex (o), behavior (p) or type of recognition (q) of the dolphins
