Introduction Copepods present the largest and most diverse group of zooplankton their feeding behavior can affect top-down bottom-up processes. Thus, how efficient is executed determines abundance copepods’ prey predators and, with that, carbon transfer storage in ecosystems. The rise anthropogenic underwater noise from shipping, oil exploration exploitation, wind farm construction operation, more, increasingly changing marine acoustic environment. This pollution have detrimental effects on biological life. Studies this topic indicate that adversely affects primary producers, mammals, fish, invertebrates. However, little data exist zooplankton. Methods Here, we investigated ingestion clearance rates copepod Acartia tonsa a motile phytoplankton as function density under ambient aquarium sound conditions when exposed to playback, harbor traffic noise. Results We measured significantly decreased A. compared conditions. negative impact was found at all given cell densities between 1k 10k cells ml −1 . Clearance were fitted Rogers random predator equation which revealed capture exposure while handling times remained same both treatments. Discussion Our results call for follow-up studies focus driven community-effects field experiments confirm laboratory predict outcome world multiple stressors. Further, underlying mechanism copepods still unknown. Noise may distract or mask hydromechanical cues prey. also physiology morphology would lead changes behavior. All potential mechanisms need be rigorously future experiments.

Airguns used in seismic surveys release high-pressure air, generating sound waves that may have adverse effects on marine life. However, knowledge of how exposure impacts zooplankton is limited. One key characteristic signals could potentially cause damage a rapid pressure drop. In this study, the drop (~2 bar) was re-created laboratory using tube. To determine range at which occurs, field around airgun array modeled. The mortality and swimming behavior were tested 2 common copepods, Acartia sp. Calanus sp., both immediately 5 h after treatment. Pressure-exposed showed higher rates (0 h: 5.6%; 10%) compared to controls, while only increased (3.3%). speed pressure-exposed 0.49 mm s -1 ; 0.52 ) lower than control treatment, whereas (2.64 differed This study demonstrates can negatively affect close range. results also show more sensitive suggesting potential species-specific from exposure. Identifying characteristics be harmful allows for accurate assessment most affected species occur.

Abstract Although there is an increasing interest in the effects of anthropogenic noise on underwater wildlife, most studies focus marine mammals and fishes while many others taxa substantial ecological importance are still overlooked. This case for zooplankton species which ensure coupling between primary producers pelagic food webs. Here, we measured lifespan, reproduction mobility laboratory-raised water fleas Daphnia magna , a widespread freshwater species, response to continuous broadband noise. Surprisingly, found significant increase survival fecundity, leading higher fitness when considering total offspring production slight population growth rate, according Euler-Lotka equation. Exposed were slower than control individuals hypothesised that energy saved from reduced was reallocated fecundity. Our results can have implications aquaculture where acoustic environment receives little attention.

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.
