Dear Marmam subscribers, I am currently studying patterns in group formation of marine tucuxi (Sotalia guianensis) in the coastal waters of Brazil, specifically the formation of large groups (aggregations) with more than 100 animals gathered in an area. I would enormously appreciate if you could provide me with information (publications, reports, personal observations) about large group formation of coastal dolphins and the underlying behaviors and environmental characteristics during these records. Thank you for your attention, Laura Laura Aichinger Dias Biology Graduate Student at Florida Atlantic University 17000 North Bay Road, Apt. 1505 Sunny Isles Beach, FL 33160 USA 1(305)956-9574 lauretadias@yahoo.com.br --------------------------------- Never miss an email again!
