“…Ambient noise levels in busy shipping lanes have recently increased (Hildebrand, ), across much of the frequency spectrum (Sertlek et al, ), but especially at lower frequencies (<500 Hz; Erbe et al, ; Bittencourt et al, ). Large numbers of smaller pleasure and recreational vessels, including things like jet skis (Erbe, ), may also result in substantial increases in noise levels in coastal waters, lakes and rivers.…”

Fishes use a variety of sensory systems to learn about their environments and to communicate.Of the various senses, hearing plays a particularly important role for fishes in providing information, often from great distances, from all around these animals. This information is in all three spatial dimensions, often overcoming the limitations of other senses such as vision, touch, taste and smell. Sound is used for communication between fishes, mating behaviour, the detection of prey and predators, orientation and migration and habitat selection. Thus, anything that interferes with the ability of a fish to detect and respond to biologically relevant sounds can decrease survival and fitness of individuals and populations.

“…Although S. bredanensis is classified as ‘Least Concern’ on the Red List of Threatened Species (IUCN, ), in the southwestern Atlantic its coastal habits make the species susceptible to anthropogenic threats such as habitat degradation, chemical and noise pollution, and bycatch (Di Beneditto, Ramos & Lima, ; Monteiro‐Neto et al ., ; Dorneles et al ., ; Netto & Di Beneditto, ; Meirelles et al ., ; Lailson‐Brito et al ., , Lemos et al ., , Bittencourt et al ., ). These studies suggest that rough‐toothed dolphin populations in the southwestern Atlantic may be affected negatively by human impacts upon the coastal zone, but the magnitude of such adverse effects is presently unknown.…”

Several delphinid species have shown genetic population structure, both between and within ocean basins. We investigated genetic differentiation in the rough-toothed dolphin, Steno bredanensis, using mitochondrial control region sequences from several localities worldwide (N = 112). Preliminary analyses indicated high levels of genetic differentiation between the Atlantic and Pacific/Indian Oceans, which were further investigated using complete cytochrome b sequences and mitogenomes. Phylogenetic analyses were inconclusive about the existence of cryptic speciation in the genus Steno. Notwithstanding this result, analysis of molecular variance and Φ-statistics analyses revealed strong population differentiation not only between the Atlantic and Pacific, but also within the Atlantic, where three populations were detected: Caribbean, southeastern Brazil, and southern Brazil. We propose that these populations be considered management units for conservation purposes. Our results provide the first perspective on the worldwide genetic differentiation of S. bredanensis.

“…However, despite a large number of marine mammal species are distributed in nearshore waters (Kaschner et al, 2006;Pompa et al, 2011) where human activities are most intense (Halpern et al, 2008;Maxwell et al, 2013), there are relatively fewer studies on the coastal acoustic environment, or soundscape, and its potential effects on marine mammals (Merchant et al, 2014;Bittencourt et al, 2014). This is further compounded by the many different types of soundscapes in shallow coastal environments because of (1) the complexity of sound propagation patterns (Urick, 1983), (2) the high diversity of animal communities (Gray, 1997), and (3) different levels of human activities (Merchant et al, 2014) at these areas.…”

The underwater acoustic field is an important ecological element for many aquatic animals. This research examines the soundscape of a critically endangered Indo-Pacific humpback dolphin population in the shallow water environment off the west coast of Taiwan. Underwater acoustic recordings were conducted between late spring and late fall in 2012 at Yunlin (YL), which is close to a shipping lane, and Waisanding (WS), which is relatively pristine. Site-specific analyses were performed on the dynamics of the temporal and spectral acoustic characteristics for both locations. The results highlight the dynamics of the soundscape in two major octave bands: 150-300 Hz and 1.2-2.4 kHz. The acoustic energy in the former frequency band is mainly associated with passing container vessels near YL, while the latter frequency band is from sonic fish chorus at nighttime in both recording sites. In addition, large variation of low frequency acoustic energy throughout the study period was noticed at WS, where the water depths ranged between 1.5 and 4.5 m depending on tidal cycle. This phenomenon suggests that besides certain sound sources in the environment, the coastal soundscape may also be influenced by its local bathymetry and the dynamics of the physical environment.
