This study investigated the emission of subaquatic noise from recreational tourism motorboats, schooners and a sea-bottom mounted water pump. Analyses demonstrated alterations in several whistle (IF: t = 2.42, P = 0.015; FF: t = −2.22, P = 0.025) and calls patterns (MIF: t = −3.13, P = 0.001; MAF: t = −3.49, P = 0.0005; FD: t = −2.21, P = 0.027; D:...


... Cetaceans may also occasionally present speci c The effects of anthropogenic noise on Guiana dolphin (Sotalia guianensis, van Bénéden, 1864), a species that inhabits estuaries and bays between southern Brazil and Honduras, are still poorly understood. A number of responses have been documented, however, including an increase in whistle rates (Bittencourt et al. 2017), a signi cant increase in the initial and nal frequency of the whistles (Martins et al. 2018), and a reduction in whistle duration (Bittencourt et al. 2017). The Guiana dolphin is classi ed as 'Vulnerable' in Brazilian waters (ICMBio 2011), and understanding the global conservation status of the species was considered to be a priority by the International Whaling Commission (IWC) in 2018. ...
