Understanding the areas of production, where the blooms go and what they become are therefore of major interest in marine ecosystem management. We used floating electronic tags developed in our laboratory for jellyfish live tracking. A special attention was put on the welfare of the organisms as the tag was floating and simply attached with a fishing line around the manubrium. <em>In situ</em> experiments were carried out in Bages Sigean lagoon (France) where a perennial population of the Mediterranean jellyfish <em>Rhizostoma pulmo</em> is established. Up to 47 deployments, from 20 min to 28h, took place in 2022 and 2023 summers. Live tracking indicated that the floating device did not influence the jellyfish trajectory nor its speed. A 28-h trajectory showed that jellyfish movement can be influenced by the wind but also by other environmental factors. The relatively small area covered by the jellyfish compared to the control float one, suggests that movements significantly influence its trajectory as a response to the environment. Jellyfish were successfully recovered suggesting in a near future repeated individual measurements processes over longer deployments.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"318 ","pages":"Article 109250"},"PeriodicalIF":2.6,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These three sources of sampling provided different dietary information. Stomach contents from dead animals presented more diverse prey than those coming from the two other sources. Overall, the fish species <em>Raneya brasiliensis</em> was the main prey item found, followed by cephalopods and crustaceans, coinciding with previous dietary reports based on scat analysis.

In this study, we investigated the ontogenic change in feeding habit of clams in natural waters based on chloroplast-targeting DNA metabarcoding. Samples of clams (spats, juveniles, adults), seawater and sediment were collected in three regions in Japan. DNA was extracted from each sample and PCR and DNA metabarcoding were performed using diatom-specific universal primers for chloroplasts (rbcL), after comparison with the universal primer for microalgae (psbA). Then, we calculated compositions of diatom genera in each sample, proportions of planktonic and benthic diatoms in gut contents of clams and similarities of diatom genera compositions between each sample. High proportions of benthic diatoms tended to be detected from spats and small juveniles with a shell length less than 2 mm. On the other hand, high proportions of planktonic diatoms were detected from gut contents of juveniles and adults with a shell length greater than 8 mm, and their composition was similar to that of diatoms in the ambient seawater. This diet shift may be attributed to the developmental completion of the inhalant siphon for filter-feeding at around 2 mm in shell length. From these results, the life history stages of the Manila clam after settlement can be divide into three phases: pedal-feeding phase from the settlement to 2 mm shell length, transition phase from 2 to 8 mm and filter-feeding phase larger than 8 mm.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"319 ","pages":"Article 109244"},"PeriodicalIF":2.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, stomach content analysis and behavioral observations have primarily been used to assess duck predation on clams. Although ducks appear to respond to water depth, their response to short-term changes in water depth (i.e., tidal height) has not been assessed in tidal flats. Therefore, a quantitative evaluation of the effects of duck predation on clams is needed to clarify the behavior of ducks on tidal flats and to conserve ducks and clams. In this study, the influence of duck predation on the clam population was investigated using anti-predation experiments on the Midorikawa River tidal flat in Ariake Bay, Kyushu, Japan. Furthermore, the relationships among water depth, duck activity, and duck flock density were investigated using a trail camera and a drone. In the anti-predation experiment during the study period, no significant difference in clam density was found between the experimental and control clam density.

Over the past 40 years, models for estimating PP using remote sensing technology have been continuously developed.

With an attempt to develop accurate and robust PP models for coastal environments from satellite measurements, this study aimed to explore machine learning (ML) methods in satellite retrieval of PP values. The California Current System (CCS), one of the world's four largest eastern boundary current systems, has abundant in-situ measurements of PP. Combining these data with remote sensing data, we developed multi-parameter fusion ML algorithms and conducted a comparative analysis with three other PP models. The results indicated that the ML model exhibited high applicability in the remote sensing inversion of PP. The inversion accuracy of the ML model (average <em>RMSE</em>: 266.3 mgC·m⁻²·d⁻¹, average <em>MAPD</em>: 49.9%, average <em>Bias</em>: 3.2 mgC·m⁻²·d⁻¹) outperformed PP models (average <em>RMSE</em>: 1127.0 mgC·m⁻²·d⁻¹, average <em>MAPD</em>: 151.6%, average <em>Bias</em>: 471.6 mgC·m⁻²·d⁻¹). The XGBoost model improves the inversion accuracy of PP in coastal waters more accurately than other models. Based on this model, we analyzed the spatio-temporal distribution characteristics of PP in the CCS from 2012 to 2022. The findings showed distinct monthly distribution patterns of PP on spatial scales, with a decrease from nearshore to offshore areas. On temporal scales, there was an increase trend from February to August, followed by a decline trend until the next February. Additionally, this study further explored the relationship between variations in PP within the CCS and climatic phenomena, specifically the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO).
