“…To date, very little is known about the additive or synergistic effects of POPs and other micropollutants, but there is evidence of increased toxicity in the pollutant mixture, as well as their bioavailability in tropical marine environments while facing climate change . Cumulative effects of multiple impacts must also be addressed for the studied populations of rough-toothed dolphins, such as habitat degradation, , ingestion of plastic (MAQUA, unpublished data) due to increased pollution, , entanglement in fishing gears, , and anthropogenic noise pollution, all of which are easily detected and present in a daily basis within the SE and S Brazilian coast.…”

Rough-toothed dolphins, Steno bredanensis, are closely associated with coastal waters in the Southwestern Atlantic Ocean, increasing the exposure to multiple stressors, such as chemical pollution. Persistent organic pollutants (POPs) are known to affect the health of cetacean species. To comprehend the potential impacts of POPs on populations’ viability, it is necessary to distinguish populations and predict their risk of long-term exposure. Blubbers of rough-toothed dolphins (n = 28) collected along the southeastern (SE) and southern (S) Brazilian coast were screened for polychlorinated biphenyls (PCBs) and pesticides in a gas chromatograph coupled to a mass spectrometer. Based on the contamination profile, a discriminant function analysis separated the rough-toothed dolphins into three ecological populations: two coastal and one offshore. POP concentrations were the highest reported for the species worldwide and highest among the delphinids in Brazilian waters, reaching 647.9 μg g–1 lw for PCBs. The SE population presented 212.9 ± 163.0, S population presented 101.0 ± 96.7, and OCS/S population presented 183.3 ± 85.3 μg g–1 lw (mean ± SD) of PCBs. The potential risk of effects triggered by elevated PCB concentrations was assessed in an individual-based model. A risk of severe decline in population size is projected for the three populations in the next 100 years, especially in SE Brazil, varying between 67 and 99%.

“…While studies have been conducted on many aspects of the biology and ecology of this species (Azevedo et al, 2010; Bisi et al, 2013; Bittencourt, Barbosa, Santos‐Neto, et al, 2020; Caballero et al, 2013; Di Beneditto et al, 2001; Di Tullio et al, 2016; do Amaral et al, 2015; Dorneles et al, 2010; Lavandier et al, 2019; Leonel et al, 2012; Lima et al, 2016; Lopes et al, 2012; Méndez‐Fernandez et al, 2018, 2020; Moreno et al, 2005), information about habitat use, abundance, and behavior are scarce in SWAO. In southeastern Brazil cetaceans face several threats, such as chemical and noise pollution, habitat degradation, and bycatch (Bittencourt, Barbosa, Bisi, et al, 2020; Di Beneditto, 2003; Moreno et al, 2005; Oliveira‐Ferreira et al, 2021; Secchi et al, 2021), and Atlantic spotted dolphins are frequent in this region (Bisi et al, 2013; Moreno et al, 2005).…”

“…Anthropogenic sounds from recreational vessels and commercial shipping are frequent in many coastal habitats, including coral reefs (Bittencourt et al, 2020;Dinh et al, 2018;. Such sounds can have a multitude of adverse physiological and behavioral effects on invertebrates and fishes (Bruintjes et al, 2016;Filiciotto et al, 2016;Holles et al, 2013;Magnhagen et al, 2017;Mensinger et al, 2018;Simpson et al, 2016;Wale et al, 2013), and can mask ecologically relevant cues (Pine et al, 2016).…”

Coral reef soundscapes are increasingly studied for their ecological uses by invertebrates and fishes, for monitoring habitat quality, and to investigate effects of anthropogenic noise pollution. Few examinations of aquatic soundscapes have reported particle motion levels and variability, despite their relevance to invertebrates and fishes. In this study, ambient particle acceleration was quantified from orthogonal hydrophone arrays over several months at four coral reef sites, which varied in benthic habitat and fish communities. Time-averaged particle acceleration magnitudes were similar across axes, within 3 dB. Temporal trends of particle acceleration corresponded with those of sound pressure, and the strength of diel trends in both metrics significantly correlated with percent coral cover. Higher magnitude particle accelerations diverged further from pressure values, potentially representing sounds recorded in the near field. Particle acceleration levels were also reported for boat and example fish sounds. Comparisons with particle acceleration derived audiograms suggest the greatest capacity of invertebrates and fishes to detect soundscape components below 100 Hz, and poorer detectability of soundscapes by invertebrates compared to fishes. Based on these results, research foci are discussed for which reporting of particle motion is essential, versus those for which sound pressure may suffice.
