There is a growing interest in the impact of acoustic pollution on aquatic ecosystems. Currently, research has primarily focused hearing species, particularly fishes and mammals. However, species from lower trophic levels, including many invertebrates, are less studied despite their ecological significance. Among these taxa, studies examining effects sound holozooplankton extremely rare. This literature review examines both marine freshwater zooplankton. It highlights two differences: few used organisms types source. Marine focus very intense acute copepods, while chronic cladocerans. But, both, various negative reported. The remain largely unknown, although previous have shown that zooplankton can detect vibrations using mechanoreceptors. perception environment be affected by sounds, potentially causing stress.

Responses sound, which could alter interactions population dynamics, expected larger-scale implications with bottom-up effects, such as food web dynamics ecosystem functioning. To improve effect better biological models bioindicators, researchers need understand how they perceive environment. Consequently, an important challenge measurement particle motion establish useable dose-response relationships soundscapes.

A bstract Among the numerous questions about human impacts on ecosystems, there is a growing interest for acoustic pollution. First studies underwater pollution focused, and showed effects, vertebrates’ behaviours. Knowledge effects invertebrates more limited huge lack concerning zooplankton species, although widely used as bioindicators in chemical Consequently, it critical to assess impact of noise zooplankton’s fitness (survival fecundity). Here, isolated water fleas, Daphnia magna , were reared from birth death presence or absence motorboat noises. Effects lifespan clonal offspring production (e.g., clutch size, number produced along life) assessed chronic exposure boat did not affect ’s fitness. The spectral temporal features sounds could explain results. This study highlights importance integrating into ecotoxicological research understand, prevent, communities.
