Dear colleagues, We are pleased to share with you a recent publication in Marine Pollution Bulletin regarding underwater noise influence in dolphin communication: Bittencourt, L.; Lima, I.M.S.; Andrade, L.G.; Carvalho, R. R.; Bisi, T. L.; Lailson-Brito, J. Jr.; Azevedo, A. F. (2016) "Underwater noise in an impacted environment can affect Guiana dolphin communication" DOI: 10.1016/j.marpolbul.2016.10.037 Abstract: This study focused onwhistles produced by Guiana dolphin under different noise conditions in Guanabara Bay, southeastern Brazil. Recording sessions were performed with a fully calibrated recording system. Whistles and underwater noise levels registered during two behavioral stateswere compared separately between two areas. Noise levels differed between the two areas across all frequencies. Whistle duration differed between areas andwas negatively correlatedwith noise levels.Whistling ratewas positively correlated with noise levels, show- ing thatwhistling ratewas higher in noisier conditions. Results demonstrated that underwater noise influenced Guiana dolphin acoustic behavior.
