Limited knowledge of these highly dynamic fisheries impedes the design and implementation of stakeholder-inclusive policies for conservation. To address this, we developed an interdisciplinary approach, combining landing data with fishing geo-locations, Very High resolution (VHR) satellite imagery and fisher interviews to model elasmobranch catch dynamics and map areas of high catch potential. We compared how elasmobranch catch rates varied by species ecology, habitat, and fisheries characteristics in Visakhapatnam and Malvan, two regions on the east and west coasts of India, respectively. We sampled 2209 fishing trips across three oceanographic seasons from landing sites at both locations in 2022-23. We recorded 5578 elasmobranchs from &gt;20 species of which at least 13 were categorised as ‘Threatened’. Gillnets, hook and line and trawl nets were the most common gears, but their use and catch rates varied considerably. Elasmobranchs had a higher catch risk on the eastern site (where they may be specifically targeted) and were generally larger. Catch rates were higher in shallow regions on the west coast and in the summer at both sites. Importantly, we demonstrate that drivers of elasmobranch catch were site and fishery specific, underscoring the need for more local-scale research for planning conservation actions. Our framework provides a robust method to study the highly dynamic and diverse nature of nearshore fisheries, which can inform conservation actions and, at the same, time, enable a bottom-up approach to conserving elasmobranchs.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107849"},"PeriodicalIF":4.8,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 proposal for the declaration of the Guguy Maritime-Terrestrial National Park, located on the island of Gran Canaria (Canary Islands, Spain), illustrates this conflict. In contrast to the jurisdictional boundary established by law along the coastline between the regional administration (land area) and the state administration (marine area), this work presents theoretical and experimental indicators that demonstrate the existence of land-sea ecological connectivity in the beach-dune system. The sedimentary analyses and wind and marine dynamics indicate the presence of a single geodynamic functional unit on the Guguy coast, where marine, wind, fluvial and slope processes are interconnected.

SSF fishers can offer vital insights into the life history characteristics of target species. Upholding the principles of good governance, the combination of conventional scientific knowledge (CSK) with local ecological knowledge (LEK) is pivotal to ensure the success of SSF management. In this study, we employed CSK and LEK to holistically assess the stocks of three commercially important mullet species in three estuaries in the Tropical Southwestern Atlantic, examining how both information sources can contribute to conservation and management efforts. For CSK, we employed a Bayesian size-based model to conduct a stock assessment grounded in prior information on life history parameters. For LEK, we conducted interviews with fishers, aiming to understand how they perceive stock status, and which factors affect these resources. The size-based model indicated significant fishing pressure, suggesting that two of the stocks are overexploited while one is operating at its maximum sustainable yield. LEK and CSK largely agree on mullet stock status but not on the causes of declines. CSK attributes the declines to high fishing pressure, while most fishers point out to environmental problems such as pollution. This underscores the importance of LEK to provide complementary information to fisheries management. By highlighting how LEK could complement SSF management, we argue that horizontal collaboration is essential in artisanal fisheries, allowing fishers, managers, and scientists an active voice in decision-making. We also identified strengths, weaknesses, opportunities, and potential threats to the mullet stocks in the region, allowing enhanced governance through collaboration among stakeholders and the scientific community.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107836"},"PeriodicalIF":4.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Based on eight periods of Landsat remote sensing images (totaling 16 scenes) from 1990 to 2024, this study extracted instantaneous waterlines using the Normalized Difference Water Index (NDWI) and Canny edge detection, determined the coastline through tidal level interpolation discretization and visual interpretation, calculated coastline change rates using the Digital Shoreline Analysis System (DSAS), constructed the Human Activity Intensity of Land Surface (HAILS) index, and employed Redundancy Analysis (RDA) to analyze the relationship between human activities and coastal changes. The results indicate: (1) Over the 34-year period, the total length of the Yancheng coastline increased from 333.09 km to 339.89 km, with the proportion of artificial coastline rising from 12.03 % to 48.11 %. The Sheyang River serves as a boundary, with the coastline changes adhering to the “southern accretion and northern erosion” pattern, where the maximum erosion rate reached 33.7 m/a and the maximum accretion rate was 380 m/a. Tidal flat area changes exhibited a “southern decrease and northern increase” trend. (2) The intensity of human activities in the coastal area increased from 0.16 % to 0.22 %, with the equivalent area of construction land expanding by 270.46 km², where the growth of construction land and aquaculture ponds was most significant, while the reduction in tidal flat area was most pronounced. (3) There exists a positive synergistic enhancement between coastline change intensity, artificialization index, and human activity intensity, whereas tidal flat area shows a significant negative response to human activity intensity. The “southern accretion and northern erosion” pattern in the Yancheng coastal zone results from the interaction between human activities and natural processes. This study provides new research perspectives on balancing the appropriateness of reclamation, coastline stability, and coastal ecosystem diversity in typical muddy coasts.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107851"},"PeriodicalIF":4.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

While the seventeen SDGs recognize the importance of a peaceful society for this world, the SDG 14 is not explicit with regard to peace. By reviewing various ocean activities and policies, using examples from the post-World War II history and capitalizing on their own research, the authors of this paper highlight modalities of human relations with the ocean that would support peaceful coexistence of nations. This analysis refers to prominent theories of conflict resolution, peacemaking and peacebuilding. Our conclusion is that adding an explicit peacebuilding dimension to the current ocean research and management practices could not only help nations to make the ocean a critical ally of sustainability, but also support peace in the world. Since human interactions with the ocean are science-intensive, the ocean's peacebuilding potential is inseparable from the objective and cooperative nature of ocean science. One of the qualities of the “ocean we want” is a peaceful ocean. Systematic research on the ocean as a peacebuilder needs therefore to be initiated. However, it requires a dedicated transdisciplinary methodology, which does not yet exist. The Ocean Decade has the potential to bring together the currently disconnected peacebuilding- and ocean-research communities and co-design methodologies and practices to fully use the ocean's capacity as a peacebuilder.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107835"},"PeriodicalIF":4.8,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144580605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Compared to conventional approaches, GswinLSTM simultaneously captures temporal dependencies and spatial correlations in wind speed data, significantly improving forecasting accuracy and robustness. The model is validated using ERA5 reanalysis data, which accurately represents offshore climate conditions.

With strong theoretical contributions and practical applicability, this model offers valuable insights for wind field operations, maritime navigation, and climate monitoring. The findings underscore GswinLSTM's potential to drive advancements in renewable energy forecasting and environmental risk assessment, making it a promising tool for future atmospheric and meteorological studies.

The Indo-Pacific humpback dolphin (<em>Sousa chinensis</em>, IPHD), a vital indicator of marine ecosystem health, is increasingly threatened by human activities and climate change, and is currently listed as Vulnerable on the IUCN Red List of Threatened Species. By integrating species distribution records with ten environmental variables, we developed species-level (SLDMs) and population-level distribution models (PLDMs) to investigate the habitat preferences of IPHDs in China and evaluate their current and future habitat dynamics under different climate change scenarios. The SLDMs identified mixed layer depth as the primary environmental variable influencing the distribution of IPHDs, while the PLDMs revealed that the key environmental variable influencing distribution differs across different IPHD populations. The SLDMs projected a continuous reduction in suitable habitat for IPHDs over the next 70 years. The PLDMs indicated that larger IPHD populations, such as those in the Pearl River Estuary (PRE), Leizhou Bay (LZB), and Sanniang Bay (SNB), may serve as critical refugia with available habitats for transfer in the future, whereas smaller IPHD populations, including Xiamen-Jinmen (XJ) and Yuedong (YD) populations, are projected to face severe and progressive habitat loss, increasing their risk of local extinction.

We first collected distribution data and associated environmental variables for common minke whales and then constructed species distribution models (SDMs) for its three subspecies across four seasons.

By incorporating autumn and spring habitat suitability indices as cost layers, connectivity analysis was used to delineate inter-seasonal migration corridors (summer to winter, winter to summer). Results indicate that environmental drivers of minke whale distribution vary among subspecies and across seasons, highlighting the importance of incorporating finer taxonomic units and temporal scales in SDM research. Suitable habitats and migration corridors are primarily located in coastal waters, where existing marine protected areas provide limited coverage, and face multiple anthropogenic threats. Therefore, future conservation efforts should prioritize these areas.
