Investigating the spatial distribution characteristics of beach sediments in mangrove habitats and their relationships with hydrodynamic conditions and vegetation dynamics is crucial for sustaining the health and sustainability of mangrove ecosystems. This study aims to explore the spatial distribution characteristics of sediments in the mangrove beach of Xiashan Sea-viewing Promenade, Zhanjiang, and their relationship with hydrodynamics and mangrove vegetation. A total of 59 surface sediment samples were collected from 6 transects in the study area. The elevation of the sampling points, as well as wave and current data during the sampling period, were measured. The sediment transport trends of the 6 transects were also analyzed. The results show that the average grain size of surface sediments in the study area ranges from -0.75 to 5.15 φ; the average sorting coefficient is 1.26, indicating poor sediment sorting; the average skewness is 0.19, with positively skewed and extremely positively skewed sediments widely distributed in the study area; the kurtosis values range from 0.36 to 2.31, with an average of 1.14, and narrow kurtosis is observed on the seaward side of the southern and northern parts of the study area. The significant wave height in the study area ranges from 0.05 to 0.17 m, the wave period ranges from 1.44 to 3.38 s, and the current velocity ranges from 1.44 to 7.44 cm·s⁻¹. The surface sediment types include gravel, sand, silt, and clay, with sand being the most abundant, followed by silt, while gravel and clay are present in small amounts, with gravel only found in small quantities near the shore in the northern part of the study area. The sand content decreases from the shore to the sea, while the spatial distribution of silt shows the opposite trend. The clay content is relatively low, with a higher concentration in the seaward area. The wave action in the study area is significantly stronger than the current action, with the strongest hydrodynamic forces occurring during the early flood tide and late ebb tide, leading to an onshore sediment transport trend. This process can increase beach elevation and stability, which is beneficial for the growth and development of mangroves.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00092-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Arabian Peninsula Region (APR), productivity of the marine and coastal fisheries is largely impacted by climate change. The present study provides perspectives of the existing fisheries management plans of the APR with special emphasis on the Sultanate of Oman (SO) by conducting a comprehensive literature survey that includes primary research articles, academic theses, reports, governmental decisions and legislations and reputable websites. The study proposes future climate-adaptive management strategies for APR and SO, emphasizing the risk assessments, stakeholder collaboration by taking a transboundary approach. Fisheries management in the APR currently faces challenges of overfishing, habitat degradation, and climate change impacts, with each country employing unique approaches; regional cooperation and sharing best practices are deemed essential for long-term sustainability. Fisheries management in the SO, a critical part of the country's economy, includes measures such as licensing and seasonal closures; however, a climate-resilient framework for pelagic fisheries is lacking, which is creating an uncertainty in fisheries management the face of ongoing climate change. Effective climate-adaptive fisheries management in the SO necessitates risk assessments, stakeholder engagement, and cross-border collaborations. The APR as a whole requires integrated short- and long-term strategies for addressing climate change impacts on marine ecosystems and fisheries, with a focus on flexibility and local participation. The study recommends ecosystem-based fisheries management, which incorporates both biotic and abiotic elements, as well as regional evaluations and co-management solutions to mitigate the effects of climate change.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00088-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 2010, the shoreline tended toward stability, which was related to changes in sediment discharge in the Minjiang River estuary. (3) Following an adaptation period of 5–15 years after sediment discharge from adjacent rivers stabilized, a new dynamic equilibrium was established. However, this equilibrium was subsequently disrupted by intense human activities, leading to renewed oscillations of erosion and accretion along the sandy shoreline.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00087-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Economically, Cape May County tourism contributed $7.7 billion in 2023 to the local economy. This study investigates the foreshore sediment textural characteristics and grain size distribution following a renourishment cycle. Sediment samples <i>n</i> = 54 were collected in March (winter) and <i>n</i> = 57 in August (summer) 2024 along cross-shore profiles from the berm crest to the high tide line. The samples were sieved and analyzed for grain size distribution, sorting, skewness, and kurtosis using sieve analysis and GRADISTAT V8.0 software. Results indicate that Wildwood beaches in the winter (pre-nourishment) were very well-sorted fine sand, and in the summer (post-nourishment), well-sorted fine to medium sand. Cape May oceanside was predominantly well-sorted medium sand, symmetrical to coarse skewed in winter and fine skewed in summer. In contrast, Bayside consisted of more poorly sorted coarse sand, including gravel. Results indicate that Wildwood and Cape May Oceanside are depositional environments during both seasons, whereas Cape May Bayside in winter is an erosive setting with sporadic high-energy events and multiple sources of sediments. Ultimately, the long-term nourishment has caused an increase in overall average grain sizes of the beaches, where coastal structures alter the natural sediment transport and wave energy reaching the nearshore, impacting the distribution of sediments. Under modern conditions with decades of future anthropogenic influence, these beaches could demonstrate a greater resilience to erosion, while being more stable. These findings are applicable to future coastal management and habitat restoration projects.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00090-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “what” consists of a series of social, economic, environmental and governance indicators, linked to the sustainable development goals, that provide a checklist for lagoon sustainability. The “how” outlines tenets of good governance with an emphasis on equity, participation, cooperation and open communication. The “who” maps the range of possible lagoon stakeholders.

All these factors potentially impact the Black Skimmer (<i>Rynchops niger</i>), a seabird that is considered vulnerable in much of its range across the Americas. This study quantified disturbances affecting two skimmer colonies within a Critical Wildlife Area in southwest Florida, a coastal area of rapidly growing human population. Skimmers experienced a wide array of disturbances that caused a total of 195 flushing events, at a rate of almost 2 per hour throughout the 3-month study period. Natural and anthropogenic disturbances were occurring simultaneously and at roughly similar frequencies at the two colonies. Weather and unexplained disturbances caused a higher portion of skimmers to flush at one colony, and weather led to longer flushing events at the other colony. Flushing responses were stronger on weekends at the second colony. Notably, breeding skimmers faced considerable disturbance despite existing within a monitored protected area. Given the overlap of disturbance types across the breeding season, this study demonstrates the need for measures to protect skimmers from anthropogenic and environmental stressors, including further study of how these factors impact reproductive success of colonies.

Our findings revealed a net increase of 865.8 km² in coastal marsh area during 2000–2020, with distinct regional variations. Coastal marsh changes were more evident north of 30°N, particularly in the Bohai Rim region (37–41°N) and the Yangtze River Delta (30–33°N). Over 75% of major coastal marsh gains (&gt; 1,250 ha) and losses (&gt; 1,000 ha) based on 25 km² hexagonal grids occurred in these two regions during 2000–2020. The increase in the proportion of major coastal marsh loss grids (&gt; 1,000 km²) from 80.0% to 89.8% in these two regions during 2010–2020 suggests that some areas continued to deteriorate, highlighting that total area changes may mask important local dynamics. While driving factors varied across latitudes, land reclamation remained the dominant reason for coastal wetland loss. Reclamation induced coastal marsh loss accounting for over 60% of the total losses across all sea regions during different periods. In the Bohai Rim, the latitudinal distribution of marsh losses aligned with aquaculture changes patterns, while marsh gains primarily resulted from ecological recovery. In the East China Sea region where the Yangtze Delta is located, accretion contributed over 65% of total gains during both 2000–2010 and 2010–2020 periods. The areas of significant coastal marsh changes in the East China Sea region spatially overlapped with the distribution range of <i>Spartina alterniflora</i>.
