“…Whether our results can be extrapolated to wild D. magna populations needs further investigation. Animals can show deviations in behaviour between the laboratory and the field (Tiselius, 1995;Prosnier, Loeuille, et al, 2023), and reduced mobility might have detrimental outcomes in the field as mobility is important to find food, to escape predators and more generally to do diel vertical migrations (Dodson et al, 1997;Larsson & Kleiven, 1997;O'Keefe et al, 1998;Roozen & Lürling, 2001; Chang & Hanazato, Knowing the indirect effects of this mobility reduction would be useful to understand noise effects on zooplanktonic community (Rojas, Desjonquères, et al, 2023;Rojas, Gouret, et al, 2023). Continuous noise can occur in the vicinity of certain infrastructures such as water pumping systems of compressors on the bank and an interesting perspective to our work would be to study how water fleas use these noisy areas.…”

“…The protocol is similar to that of Prosnier, Rojas, et al (2023). Gravid D. magna were collected (from the storage aquarium) and isolated in 50-mL jars containing Volvic® water, known as a good medium for D. magna (B. Prosnier from Eau de Paris, a French water industry, pers.…”

“…In a previous study, we exposed the water flea Daphnia magna, a common freshwater zooplankton often used as model species in ecotoxicological studies Reynolds, 2011;Bownik, 2017Bownik, , 2020Tkaczyk et al, 2021;Ebert, 2022), to a playback of nautical activity from birth to death and found no effect on survival nor fecundity . To our knowledge, there are only two other long-term studies on zooplanktonic community (including or not fish as top predator) exposed to boat noise (Rojas, Desjonquères, et al, 2023;Rojas, Gouret, et al, 2023). They show complex effects with different impact on the various species.…”

“…Considering the successive boat passages as a succession of acute stressors, whilst being not exactly the same, nautical activity could be classified as a chronic intermittent stress (Ladewig, 2000). If the impact of noise is dose-dependent (Tyack & Thomas, 2019), for instance through the simulation of mechanoreceptors, then a continuous exposure to noise such as near water catchment systems or in aquatic husbandries could be more impactful than nautical activity (intermittent noise (Prosnier, Rojas, et al, 2023; Vereide et al, 2023)) and one-day exposure (acute noise (Fields et al, 2019; Kühn et al, 2023)). To test this hypothesis, we did a laboratory experiment where we exposed D. magna to continuous broadband noise for their entire life (about one month, from birth to death).…”

Although there is an increasing interest in the effects of anthropogenic noise on animals, aquatic studies mainly focus on organisms with hearing systems (marine mammals, fish, great arthropods) while many others of substantial ecological importance are not considered. Here we show that the water flea Daphnia magna, a widespread zooplankton species serving as food source for higher trophic levels, could be affected by noise pollution in a way that we did not expect. We found that isolated individuals exposed to a continuous broadband sound have a higher survival and fecundity, thus a higher fitness. We also found that they are slower than individuals not exposed to additional noise. It could be that the energy saved from reduced mobility is reallocated to fitness. In natural systems, this reduced velocity should result in a more negative outcome for Daphnia's fitness due to competition and predation. Our result highlights that, despite the absence of a known hearing system, a small crustacean can be affected by noise. Consequently, anthropogenic noise can not only affect communities through top-down cascading effects, when it changes the behaviour of top-predators like fish, but also via bottom-up effects with alterations in zooplankton.

“…For instance, in a freshwater community, unpredictable noise should affect more fishes, at top trophic levels, than invertebrates. But if there are various effects within zooplankton community, as expected, leading to bottom-up effects (Rojas, Desjonquères, et al, 2023;Rojas, Gouret, et al, 2023). Zooplankton is highly diverse and predatory species might react differently than their zooplanktonic prey.…”

Ecotoxicological studies mainly focus on chemical pollution, however, since past decades, there has been a growing interest for the acoustic pollution. Previous studies on underwater acoustic pollution showed that noise affects vertebrates' behaviour, like fish and marine mammals. However, little is known about other organisms. Consequently, we studied important lacking aspects, well known with chemical pollution: the effect on a key zooplankton species (used as bioindicator) and the effect on fitness (survival and fecundity). We exposed isolated water fleas, Daphnia magna, to chronic boat noise or to a silence broadcasted as control, from birth to death. We measured effects on lifespan and clonal offspring production (e.g., clutch size, number of produced offspring along life). We did not observe any effect of the chronic boat noise exposition on Daphnia's fitness. These results are consistent with results on previous acute noise exposure, but also opposite to other ones found with acute and chronic noise effect. Thus, we discuss how the noise structure and temporal pattern could affect its impacts on aquatic organisms. Our work highlights that noise pollution should be integrated in ecotoxicological studies, but also that some particular aspects of this pollutant should be considered differently than chemical pollutants.
