For the purpose of this study all dolphin sightings were classified as groups or aggregations. Groups (N = 268, x = 20, range = 1-90) consisted of dolphins in apparent association usually engaged in the same behaviour and moving in the same direction. Aggregations (N = 108, x = 204, range = 100-450) consisted of temporal association of numerous groups gathered in an area, totalling several hundred individuals usually engaged in the same behavior but not necessarily moving in the same direction. Guiana dolphin groups and aggregations differed significantly in behavioral activity, spatial and temporal distribution and age composition. Most aggregated dolphins were engaged in foraging/feeding activities and primarily located at the interior of the bay, and also, aggregations were more likely recorded during morning hours and had more neonates and calves present when compared to groups. The plotted global positioning system (GPS) records of aggregations formed two distinct clusters of distribution within the bay, indicating potential areas where conservation strategies could be implemented.\r\n\r\nDataset credit : Projeto Boto Cinza, a project from the Instituto Boto Cinza","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":null,"OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":"Dias, L.A., D.
