Smaller individuals are more prone to intertidal stressors than their larger conspecific; thus, reaching refuge sizes is crucial for their survival. There is no clear consensus about the morphological adaptations that small filter-feeding individuals may use to compensate for its greater mass-specific metabolic requirement relative to that of a larger conspecific. Food acquisition in filter-feedings is not only determined by the gill size but also by the efficiency of particle retention and transport rate; trade-offs between these variables may explain why smaller individuals are more efficient at acquiring energy. In this study, we examined the mechanisms underlying feeding responses in relation to body size in the intertidal suspension-feeding bivalve </span><em>Perumytilus purpuratus</em>. Clearance rate, flow rate, particle transport rate, and gill cilia development were compared over a range of sizes (7–35 mm shell length). Our results showed that small individuals possess a gill activity that makes them more efficient at collecting and transporting food particles than their larger conspecifics. Water flow rate, clearance rate, and particle transportation throughout the gill were higher per standardized gill area in smaller than larger individuals. Although the gill filaments are not all fully developed in smaller individuals, the old filaments are functional in capturing and transporting particles, which makes them more efficient per gill area than larger specimens.

Adult cockles, <em>Austrovenus stutchburyi</em> (in New Zealand), are key organisms on intertidal sand flats that influence sediment properties, and their removal could impact the stability of the seabed and affect crucial feedback processes in this system. We conducted a field experiment to explore our hypothesis that the loss of adult cockles will increase sediment transport and resuspension non-linearly. Changes in sediment transport regimes will then influence the properties of sediment such as grain size, organic content, and chlorophyll <em>a</em> content. We also expected that the direction and magnitude of this effect would depend on the varying environmental characteristics across the sites, such as hydrodynamic activity and sediment grain size. We excluded adult cockles from 3 × 3 m intertidal plots at 15 sites across a natural adult cockle density gradient (300–3500 ind/m²). After seven months, sediment traps were deployed in exclusion and control plots to measure the sediment transported over two tidal cycles associated with the bedload and water column with differing densities of adult cockles. Adult cockle density was a significant predictor in all models to explain sediment transport and accounted for the largest proportion of variability explained. Relationships between cockle density and sediment transport changed between sites and over time. In these situations, simple linear relationships were not always apparent due to the interacting effects of cockle density, hydrodynamic process, and sediment characteristics. The influence of adult cockles on sediment transport was also affected by the standing stock of microphytobenthos and interacted with the mud content in their surrounding environment. Our study demonstrates the existence of an important feedback between adult cockle density, sediment stability and sediment transport that is mediated by hydrodynamic processes and sediment characteristics.</p></div>","PeriodicalId":50197,"journal":{"name":"Journal of Experimental Marine Biology and Ecology","volume":"570 ","pages":"Article 151975"},"PeriodicalIF":2.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0022098123001077/pdfft?md5=39c65d819d236595d612d55a0fd993e8&pid=1-s2.0-S0022098123001077-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138453911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the effects of noise on sound emission, sand digging activity, and emergence from the sand surface by green turtle (<em>Chelonia mydas</em>) hatchlings. Acoustic recorders and infrared cameras were used to investigate the behavior of hatchlings in sand-filled chambers under three acoustic conditions: 1) a control treatment, which was silent throughout the experiment; 2) an environmental noise treatment, which exposed the hatchlings to white noise (WN) at a sound pressure level (SPL) approximately 13 dB higher than that of the control, which is similar to that of a natural beach; and 3) a loud noise treatment, which exposed them to WN at an SPL approximately 25 dB higher than that of the control. The WN ranged from 0 to 4 kHz with a repeating cycle of 30 min sound emission and 2 h 30 min silence. Sound emissions from green turtle hatchlings were detected; however, the amount of sound emissions was too small to discuss their ecological significance. The time to emergence and total number of digging bouts in the 24 h pre-emergence periods were not significantly different among treatments; however, the number of digging bouts was significantly higher during loud noise exposure. The response to loud noises may play a role in allowing hatchlings to escape from threats and/or coordinate synchronous behavior among multiple individuals. However, because the number of digging bouts decreased after loud noise exposure, prolonged exposure to loud noise may have detrimental effects on hatchlings, such as depletion of the energy reserves available to the hatchlings.

In the northwest Atlantic, the stock of black sea bass (<em>Centropristis striata</em>) steeply declined during the 1980s. While population crashes of fished bivalve species coincided with those of black sea bass, the role of black sea bass in driving trophic cascades that indirectly influence bivalve survival has largely been overlooked. Over the past decade, black sea bass have not only been recovering in abundance but warming water temperatures have been driving a northward expansion of the extent of their seasonal migration, resulting in a particularly strong relative recovery along the south shore of Long Island, New York. To explore whether black sea bass alter the foraging rates of mud crabs (<em>Dyspanopeus sayi</em>) on a species of bivalve, blue mussels (<em>Mytilus edulis</em>), we manipulated the presence and position of sea bass within an array of mesocosm tanks. We found that the presence of black sea bass reduced the proportion of blue mussels consumed by mud crabs. Black sea bass presence indirectly elevated blue mussel survival by as much as 47.7% by reducing mud crab per capita consumption of blue mussels by 57.9%. However, there were limitations to the nonconsumptive effects of black sea bass that appeared to depend on their proximity to mud crabs. While our results are from an experimental setup with a simplified food chain and are context dependent, they emphasize the importance of studying how nonconsumptive effects of specific marine predators influence trophic cascades from both conceptual and applied coastal resource management standpoints. Our results suggest that the recovery of black sea bass may bode well for the population restoration of several species of bivalves within estuaries throughout their range. Further, our study provides evidence that indicates that the nonconsumptive effects of a recovering marine predator can indirectly elevate the survival of a basal food resource species.</p></div>","PeriodicalId":50197,"journal":{"name":"Journal of Experimental Marine Biology and Ecology","volume":"570 ","pages":"Article 151964"},"PeriodicalIF":2.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0022098123000965/pdfft?md5=54bd25f99f41c30161fb7b09f4039a0a&pid=1-s2.0-S0022098123000965-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134667071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
