The detailed study of changes in benthic communities related to these phenomena is becoming urgent, due to the increasing intensity and frequency of hurricanes recorded in recent decades. Slow-growing benthic sessile organisms are particularly vulnerable to mechanical impacts, especially the large long-lived species with branched morphology that structure Mediterranean coralligenous assemblages. The present study evaluates the effects of the severe storm occurred in October 2018, and classified as one of most violent that ever struck north-western Mediterranean coasts, on two gorgonian species, the scleralcyonacean Corallium rubrum (with a solid carbonate axial skeleton) and the malacalcyonacean Paramuricea clavata (with a flexible proteinaceous axis). Comparing the cover and density of the two species before and after the severe storm, C. rubrum showed a decrease of more than 50% in one surveyed site. In contrast, P. clavata population did not show a decrease, and exhibited the highest density and cover in the same site, thanks to the high hydrodynamic condition which are favourable for this species. In this study, cover evaluation proved to be more time-efficient than counting colonies, and reduced the risk of errors. The present example highlighted the importance of continuous monitoring, including the assessment of the biological and ecological traits of the species, to provide a complete picture of their populations for conservation planning.</p>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"204 ","pages":"106917"},"PeriodicalIF":3.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877525","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}

Although the phenomenon of scallop strandings has been recognized for a long time, the lack of environmental records has made it difficult to thoroughly study the meteorological conditions that trigger these events. The availability of reanalysis data has the potential to address this data gap; however, its feasibility must first be validated. To address this, the first step was to characterize and compare hourly wind intensity (m/s) and direction (degrees) data from the fifth-generation global climate reanalysis (ERA5), provided by the European Centre for Medium-Range Weather Forecasts, with in situ wind data for the 2013-2020 period. The study focused on wind conditions during reported Tehuelche scallop strandings along the northern coast of the gulf. Subsequently, a historical search for southerly windstorms with characteristics similar to those responsible for past strandings was conducted using the ERA5 database, covering the period from 1950 to 2023. Overall, ERA5 accurately captured the dates, durations, intensities, and directions of southerly windstorms at high temporal resolution (hourly), though with a slight tendency to underestimate wind intensities of higher winds. The estimated mean annual frequency of ERA5-detected southerly windstorms with intensities higher than 11 m/s was 5.4 storms per year, with durations ranging from 12 to 74 h. These windstorms can occur throughout the year, with an increased frequency and duration during winter. ERA5 proved to be a valuable tool for characterizing windstorms, complementing in situ data and providing insight into past stranding events where no observational data were available.</p>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"204 ","pages":"106914"},"PeriodicalIF":3.0,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877520","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}

Detecting oil spills accurately using synthetic aperture radar (SAR) images is crucial for protecting the environment. However, oil spill targets in SAR images are small and resemble other objects \"look-alike\". Traditional semantic segmentation networks for MOSD may lose critical information during downsampling Hence, we propose a shape-aware and adaptive strip self-attention guided progressive network (SAGPNet) for MOSD. Firstly, we adopted the progressive strategy to reduce detailed information loss. Second, we improved the traditional U-Net by redesigning its encoder unit. Specifically, we proposed a shape-aware and multi-scale feature extraction module and an adaptive strip self-attention module (ASSAM). These modifications allow the model to extract shape, multi-scale, and global information during the encoding process, addressing the challenges posed by small targets and \"look-alike\". Third, we utilize the ASSAM to extract global features from the final encoding layer of the earlier stage of the progressive network to guide the encoding features of the subsequent stage, aiming to recognize the overall shape of the oil spill and ensure that the model preserves crucial contextual information, further mitigate the information loss caused by downsampling. Finally, we designed a joint loss to address pixel imbalance between oil spills and other targets. We use three public oil spill detection datasets to evaluate the performance of SAGPNet. The experimental results show superior performance compared to other state-of-the-art methods, highlighting the effectiveness of SAGPNet in addressing the challenges associated with MOSD.</p>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"204 ","pages":"106904"},"PeriodicalIF":3.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877583","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}

We also used GoPros to record predator identity, number of strikes and time to strike in ALAN and daylight treatments.

Understanding the impact of environmental and human factors on fish stocks and yields and how they might change is crucial to ensure the sustainable use of aquatic resources. We developed an ecosystem model using Ecopath and Ecosim (EwE) to investigate changes in target species biomass and ecosystem attributes over 83 years (2017-2100) caused by different scenarios of fishing pressure and ocean warming in the Brazilian Northeastern continental shelf. The simulations considered three IPCC climate change scenarios (RCP2.6 [0.42 °C], RCP4.5 [1.53 °C], and RCP8.5 [4.02 °C]) and four fishing pressure scenarios: two with increased pressure (10% and 30%) and two with decreased pressure (-10% and -30%). The Ecopath model indicated that the Brazilian Northeastern continental shelf ecosystem is a grazing-based system with high biomass in macroalgae and detritus compartments, supporting a diverse community of consumers. Our simulations projected overall reductions in the biomass of target species, mainly under extreme climate change. Increasing temperatures and fishing efforts reduced the biomass of large predatory species and the food web length in several scenarios. Although projected changes in ecological network and information metrics were of lower magnitude, results predicted declines in production/respiration ratio, material cycling, and ascendency (variable related to trophic specialization, internalization, and material cycling) with climate change. These declines were likely linked to increased respiration rates, metabolic costs, and lower trophic efficiency with elevated temperatures. Together, our results show how climate change and fishing pressure can change the structure of coastal ecosystems, potentially leading to undesirable alternative states for fisheries. Our approach demonstrates the effectiveness of ecosystem-based modeling in projecting likely trajectories of change, which can be especially useful for resource management in data-limited conditions.</p>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"204 ","pages":"106909"},"PeriodicalIF":3.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864638","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}

The combined spectral indexes suggest that the transformation of DON is significantly more active in summer than in winter. Additionally, most stations exhibited low DIN:DIP ratios (<16) and relatively high chlorophyll a concentrations (>2 μg/L) during the summer months, while DIP concentrations in Daya Bay remained generally low (<1 μmol L^-1).
