In addition to the well-known extraordinary changes in visual appearance they can generate at level of their mantle, cuttle-fish produce various body configurations combining chromatic, postural, and locomotion patterns, both for camouflaging communication. We introduce a previously undescribed communication display two cuttlefish species: Sepia officinalis bandensis. The four “arm wave signs” are stereotyped arm movements consisting long-lasting, expressive, repeated sequences undulations arms, which be combined expressed following specific patterns. Using non-invasive behavioral experiments, we tested hypothesis that represent multimodal displays. To assess role cues, recorded videos animals signing played them back individual participants. When seeing movies, waved display. Most importantly, were more likely when movie was upright (original) configuration as opposed flipped upside-down, similar manner humans perceive faces other socially relevant visually striking display, signs mechanical waves water, prompting us explore possibility may also perceived via mechanoreception. playback experiments those adopted vision, obtained preliminary evidence support this hypothesis, indicating signals involving vision Our new result on with opens up novel possibilities understanding vibration-mediated through lateral line and/or statocysts cephalopod species an example convergent evolution vertebrates.

Meta‐analytic assessment of physiological markers for decapod crustacean welfare

Fish and Fisheries, Год журнала: 2023, Номер 25(1), С. 134 - 150

Опубликована: Окт. 25, 2023

Abstract Decapod crustacean welfare is not only an ethical consideration for legislative purposes. Under culture and fishery settings, poor environmental conditions operator practices can cause stress, which compromises the immune system increases risk of disease. For finfish, there are established animal (group, individual) indicators. This case crabs, lobsters or shrimp. While environment‐based indicators like temperature, pH oxygen levels easily transferable, no consensus a common measure stress to monitor in decapod crustaceans. To address this shortcoming, we conducted meta‐analysis primary literature test relationships between haemolymph (blood) condition, example, glucose, L ‐lactate, haemocytes ( n = 8), sources physical handling, trawling, emersion transport 12). Despite variations effect sizes 459), generalised linear mixed models repeatedly ranked ‐lactate (followed by urea glucose) as most significant physiological predictor haemolymph, with trawling followed closely impactful stressors. Duration post (stress) exposure, sex (male, female), water temperature moult stage (pre‐, inter‐, post‐moult) were associated significantly prediction using selected biochemical cellular parameters, however, status was undefined ~48% should be interpreted caution. We present evidence that quantitating represents physiologic operational indicator crustaceans, complements existing condition/vigour indices.

Опубликована: Март 16, 2023

Introduction Noise pollution is a major stressor in the marine environment; however, responses of economically and ecologically important invertebrates, such as oysters, are largely unknown. Methods Under laboratory conditions, we measured acute behavioral physiological eastern oysters ( Crassostrea virginica) to sound treatments mimicking human activity environment. Results Oysters immediately reduced their valve gape under simulated pile driving sound, but not drilling or boating sound. Pile-driving also adductor muscle glycogen, triglyceride. None affected longer-term (12 hours) levels after administration sounds. Interestingly, neither nor gaping were correlated with glycogen content on individual level, suggesting that observed mechanistically driven by energetic physiology. Discussion Our results suggest C. virginica responds some, all, anthropogenic Future studies assessing downstream effects growth, reproduction, survival wild needed better understand sounds oyster populations biological communities they support.

The copepod Acartia sp. is more sensitive to a rapid pressure drop associated with seismic airguns than Calanus sp.

Marine Ecology Progress Series, Год журнала: 2024, Номер 730, С. 15 - 30

Опубликована: Янв. 8, 2024

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.

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.

Anthropogenic noise disrupts acoustic cues for recruitment

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 291(2027)

Anthropogenic noise is rising and may interfere with natural acoustic cues used by organisms to recruit. Newly developed technology provides enriched settlement boost recruitment of target navigating restoration sites, but can it in noise-polluted sites? To address this dilemma, we coupled replicated aquarium experiments field experiments. Under controlled laboratory conditions, enrichment boosted 2.57 times the absence anthropogenic noise, yielded comparable its presence (i.e. no boosting effect). Using same technique, then tested replicability these responses real-world settings where independently ‘sites’ are unfeasible owing inherent differences soundscapes. Again, increased was low (by 3.33 times), had effect at a site pollution. Together, laboratory-to-field outcomes indicate that mask signal enrichment. While pollution reduce effectiveness enrichment, some our reported observations suggest per se might also provide an attractive cue for oyster larvae These findings underscore complexity larval behavioural stimuli during processes.

Although there is an increasing interest in the effects of anthropogenic noise on underwater wildlife, most studies focus marine mammals and fish, while many other taxa substantial ecological importance are still overlooked. This case for zooplankton species, which ensure coupling between primary producers fishes pelagic food webs. Here, we measured lifespan, reproduction, mobility laboratory-raised water fleas Daphnia magna, a widespread freshwater response to continuous broadband noise. Surprisingly, found significant increase survival fecundity, leading higher individual fitness when considering total offspring production slight population growth rate according Euler-Lotka equation. Exposed were be slower than control individuals, discussed potential links fitness. Our results can have implications aquaculture in-lab (e.g., ecotoxicology) where acoustic environment receives little attention. Chronic associated with certain human activities, but consequences natural populations might differ as reduced velocity could negative outcomes competition predation. work one few showing effect suggests that should better accounted laboratory studies.
