Fishing intensity and climate change are among the most significant pressures, with the former being difficult to regulate in open-access systems and the latter increasingly disrupting key ecosystem services, such as biodiversity and sediment stability. Despite separate evaluations of these drivers, long-term studies examining their combined impacts within social-ecological systems are limited. This study leverages a unique 40-year dataset of beach sampling surveys, coupled with morphodynamic, climatic, and economic variables, to evaluate their relative effects on the abundance of the adult yellow clam (<em>Mesodesma mactroides</em>) population subject to artisanal harvesting at Barra del Chuy beach, Uruguay. Using MARIMA models and autocorrelation analysis, the study identified a transition in dominant drivers: human-driven factors shaped abundance from 1983 to 1992, while climate-driven factors prevailed from 1993 to 2023. This shift marks a transition from economic to environmental dominance, resulting in a regime shift characterized by a sudden and persistent alteration in yellow clam abundance. These changes reinforce previous findings that detected shifts in community structure, ecosystem dynamics, and the loss of key ecological functions. The long-term analysis reveals a synergistic interaction between regional climatic factors and local morphodynamic variables (e.g., grain size), while economic drivers, such as CPUE and unit price, play a secondary role. These results emphasize the importance of adaptive management strategies that integrate climate-driven dynamics with traditional economic considerations to foster the sustainable harvesting and conservation of sandy beach ecosystems.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"263 ","pages":"Article 107613"},"PeriodicalIF":4.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143550571","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}

However, comprehensive understanding of their zoning impacts remains limited. This study investigates the effects of zoning on fish populations within Shengsi Marine Park, a prominent MMPA in the Yangtze River Delta known for its significant resource utilization and human intervention. Using Generalized Additive Models (GAMs), we evaluated how zoning influences fish community characteristics, hypothesizing that higher protection level zones and their adjacent areas would show increased values across various fish community indicators. Our results partially supported this hypothesis: total species richness and the biomass of low commercial importance (LCI) species tended to be highest in the highest protection level zone. In the second protection level zones, only the biomass of high commercial importance (HCI) species was tended to be higher than that in the third protection level zones. Notably, zones adjacent to the highest protection level zone showed enhanced biomass of HCI fishes, indicating potential spillover effects. The relative influence of zoning varied across ecological indicators: the mean size of moderate commercial importance (MCI) species demonstrated the highest relative influence at 18.86%, followed by total species richness at 15.49%, and the mean size of all species at 14.81%. In contrast, total abundance had the lowest influence at 0.03%, with LCI abundance and biomass at 0.03% and 0.18%, respectively. While zoning significantly influenced both HCI and LCI species, the impacts were more pronounced for HCI species, further supporting our hypothesis regarding differential impacts based on commercial importance. Multivariate analyses indicated that zoning explained 7% of species assemblage variation. Pairwise comparisons highlighted significant differences between third protection level zones, with <em>Cynoglossus lighti</em> emerging as the most influential species, contributing 9% to total zone dissimilarity. This study provides novel insights into the ecological effects of zoning in Chinese MMPAs and underscores the potential of MMPAs as effective spatial management tools that integrate marine conservation and fisheries management.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"263 ","pages":"Article 107599"},"PeriodicalIF":4.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526748","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 governing stress equations are utilized to establish the relationship between stress distribution in critical cable layers and the local cable configuration. In additional, an integrated safety O&amp;M database are established, and critical results are intuitively presented in a 3D dynamic cable model. Compared with conventional Date-driven DT methods, the proposed models only utilizes three inclinations for cross-section stress distribution reconstruction. Furthermore, this DT model effectively combines the monitoring data with the physical cable characteristics, which has an improved applicability to all serving conditions. In order to verify the accuracy of the proposed framework, a DT model with experiment and numerical simulations are meticulously executed.

In addition, this is a unique landscape in which tourism and summer vacations occur throughout the year. Consequently, there is a risk to visitors and residents who often get too close to the slopes or sit at the base of cliffs, exposing themselves to natural hazards. This study aimed to assess the hazards faced by beach visitors with respect to the occurrence of mass movements. Two methodologies were combined: CoastSnap NE participatory monitoring and photogrammetry using unmanned aerial vehicles (UAV), which made it possible to identify and account for cliff movement events. The results indicated that between May 2021 and January 2022, there were 106 mass movements, including falling blocks, landslides, and debris flows, which moved up to 18 m from the slope. In addition, it was evident that the greatest number of events occurred during the rainy months in the region, highlighting a greater hazard during this time of the year. The results also made it possible to delineate hazard zones, indicating areas where beach visitors were more or less likely to be struck by rock displacements from cliffs.

We found that human activities, such as intertidal mudflat reclamation and diminished sediment supply from watershed, have disproportionately impacted recent intertidal area change, causing a sixfold greater impact than natural factors of tide, wave, and river runoff combined. Hindcasting using numerical model revealed a unique coastal erosion mechanism post-reclamation and Three Gorges Dam (TGD): a reduced suspended sediment deposition threshold due to sediment fining coupled with increased longshore transport due to wetland lost exacerbates coastal erosion. Various restoration strategies were modelled to identify an approach that could rehabilitate the squeezed tidal flats and degraded wetlands. Our results favor an innovative hybrid “green-grey” structure, combining traditional seawalls (“hard” engineering) with strategically designed long-armed T-groynes (“grey” solution) alongside an integrated saltmarsh (“green” solution) to promote tidal flat growth. This hybrid setup, through a biogeomorphological feedback, captures 30% more sediment than the solely “grey” infrastructure, halving the time needed for tidal flat restoration.
