Despite this, previous studies have determined benthic oxygen uptake under simulated conditions using traditional flux methods, overlooking the dynamic nature of coastal regions that can affect oxygen exchanges with processes occurring on different time scales. In this study, tidal variability of benthic oxygen fluxes in a mussel farm was examined using the aquatic eddy covariance (AEC) technique. Four deployments were conducted during neap and spring tides in the Ría de Vigo (NW Spain). Two AEC systems were concurrently deployed, one on each side of a mussel raft to measure benthic oxygen fluxes during tidal ebbs and floods. During neap tides, significantly higher oxygen flux was observed during floods (mean ± SD = −64 ± 34 mmol m⁻² d⁻¹) than ebbs (−42 ± 25 mmol m⁻² d⁻¹). This was due to higher velocities and associated shear stress. Conversely, during spring tides, oxygen fluxes were significantly higher during ebbs (−67 ± 34 mmol m⁻² d⁻¹) than floods (−51 ± 29 mmol m⁻² d⁻¹) despite higher velocities for floods. We suggest that this might be due to spatial differences in the shear stress, and possibly in resuspension, caused by bottom roughness variations. These differences in bottom roughness with tidal current direction is associated to the inhomogeneous distribution of mussel shells below the rafts. Measurements showed that the magnitude and direction of tidal currents modulated benthic oxygen fluxes by resuspending organic-rich sediments in shallow coastal ecosystems. Our results indicated that tidal driven resuspension enhanced oxygen consumption, and suggest that future mussel farms should be placed in deeper marine environments where this effect is reduced.</div></div>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"205 ","pages":"Article 107003"},"PeriodicalIF":3.0,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the tolerance and adaptive mechanisms of zooplankton to HABs remain poorly understood. This study examines the behavioral and feeding responses of the cruise-feeding copepod <em>Centropages dorsispinatus</em> to summer HABs in the East China Sea (ECS), focusing on interactions with the blooming diatom (<em>Skeletonema costatum</em>) and dinoflagellates (<em>Prorocentrum donghaiense, Karenia mikimotoi, and Alexandrium tamarense</em>). Using short-term incubations and high-speed filming, we compared the ingestion rates and behaviors of <em>C. dorsispinatus</em> fed mono-algal diets and mixed diets containing neutral distraction particles (polystyrene beads). The results revealed that <em>C. dorsispinatus</em> obtained limited carbon from each algal diet (1.02–7.02 μg C cop.⁻¹ day⁻¹). The presence of distraction particles reduced carbon intake from <em>S</em>. <em>costatum</em>, <em>P</em>. <em>donghaiense, and A</em>. <em>tamarense</em>, but significantly increased intake from the healthy control, <em>Platymonas helgolandica</em>. Behavioral responses varied among algal diets: compared to <em>P</em>. <em>helgolandica</em>, <em>C. dorsispinatus</em> exhibited more frequent but shorter swims in <em>S</em>. <em>costatum</em> diets and less frequent swims in <em>K</em>. <em>mikimotoi, and A</em>. <em>tamarense</em> diets. These algal-specific responses were generally mitigated when copepods simultaneously exposed to the neutral distraction particles. Copepods achieved higher carbon intake with lower mechanical energy expenditure when grazing on large dinoflagellates compared to diatoms. We suggest that cruise-feeding copepods can actively adjust their behavior to adapt to varying food conditions, including the density, morphologic characteristics, and toxicity of algae. It allows copepods to better survive and forage in dinoflagellate HABs than in diatom HABs. However, the low ingestion rates observed limit the potential for cruise-feeding copepods to exert top-down control on HABs.</div></div>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"205 ","pages":"Article 107005"},"PeriodicalIF":3.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that <em>E. acoroides</em> could tolerate high temperature (35 °C) and hypoxia (2.65 mg L⁻¹) individually for 24 h. However, exposure to both stresses simultaneously led to severe, irreversible physiological damage, highlighting a synergistic effect that surpassed the additive impact of each stressor alone. Combined stresses markedly impaired PSII, reduced photosynthetic rate and chlorophyll content, alongside elevated oxidative stress. Transcriptomic analysis indicated that high temperature intensified metabolic stress, while oxygen deficiency forced a shift from aerobic to anaerobic respiration, resulting in energy deficits. Furthermore, the lack of oxygen caused the accumulation of electrons, which triggered excessive production of reactive oxygen species. Despite the antioxidant enzyme system's active response, it was unable to mitigate the overwhelming oxidative stress, leading to irreversible oxidative damage.
