Here, we present a practical sampling framework covering the key field protocols of sedaDNA research, from field collection to laboratory subsampling, with emphasis on contamination control at each step. We review recent sedaDNA applications across multiple research fields, highlighting the growing interdisciplinary relevance of the technique. Particular attention is given to the challenges of DNA preservation in dynamic depositional environments, including coastal and semi-arid regions, where shallow, physically reworked sediments and recurring human disturbance amplify degradation and contamination risks. A Brazilian case study from Itapipoca, Ceará, illustrates how the absence of basic contamination precautions during excavation of Late Pleistocene megafaunal deposits produced metabarcoding results dominated by modern domesticated and synanthropic taxa, making the dataset uninterpretable for paleoecological reconstruction. Together, the guidelines and case study demonstrate that rigorous contamination control is not optional but essential to credible sedaDNA research, especially in tropical and coastal systems, environments that are scientifically underrepresented and increasingly threatened by anthropogenic change.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"9 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-026-00155-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133210","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}

Previous studies have shown the impact of dredging on planktonic and benthic species, which were not correctly measured by the Brazilian dredging standard CONAMA Resolution 454/12 (2012). Given this, the present study compared two acid extractions targeting metal bioavailability (1 M HCl and acetic acid) in sediments from four areas of GB sampled in summer and winter, before and after resuspension. The results showed that Zn concentrations exceeded the standard in all samples in extractions methods and in two seasons after resuspension. In winter, three of the four areas showed concentrations exceeding levels 1 and 2 of CONAMA Resolution 454/12 (2012), both before and after resuspension. The bioavailability change index (BC) was applied to show the remobilization of metals in the sediment after dredging. Results evidenced that Zn remobilization occurred after resuspension for all samples and in most resuspension intervals, indicating an environmental risk related to the resuspension activity. This demonstrates the efficiency of using bioavailable extractions for the monitoring of dredging activities. In addition to being cheaper and easier to perform than the pseudo-total extractions recommended in most global standards, it provides valuable information for improving dredging management policies. According to the results, a revision of the dredging standard is recommended, considering the inclusion of bioavailable extractions.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"9 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-026-00149-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132673","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}

Modeled estimates of SLR thresholds beyond which coastal wetlands convert to open water suggest that landscape scale estimates of wetland loss vary with geomorphic setting, upland barriers to migration, vegetative tolerances to flooding, sediment supply, and tidal ranges among others. Landscape scale examples from long-term observations are sparsely available but needed to interpret the significance of data collected from small and large sampling plots, after occasional storms, of various observation lengths, and regional SLR variations. A long-term data set in 15 min Quadrangle maps from the northern Gulf of Mexico is available to evaluate some of these threshold factors. Dredging for canals is the dominant stressor for losing 27% of the 14,501 km² of microtidal coastal lands existing in 1934. There is a strong linear relationship between dredging canals and wetland loss from 1934 to 1990. Compared to 1980 to 1999, SLR in the GOM doubled from 2000 to 2022 at a steady 10 mm yr⁻¹. This recent doubling presented an opportunity to test if there was a SLR impact effect on wetland loss vs. canal density from 1934 to 2016 compared to from 1934 to 1990. No acceleration in the slope or change in intercept was observed as SLR accelerated and there was a coincidental rise and fall in both coastal wetland loss and the number of dredging permit issued in the last 95 years. We conclude that a 10 mm yr⁻¹ SLR has not (yet) become a synergistic stressor on wetland loss on this coast, where human-driven effects on wetland loss continue to accumulate. We anticipate that the legacy effect of canal dredging will eventually work together with SLR to accelerate the rate of wetland loss.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"9 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-026-00153-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148986748","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}

This qualitative study investigates the psychological, physical, and social therapeutic benefits of coastal residents living in Akosua Village, Ghana, through the Blue Mind Theory, Biophilia Hypothesis, Social Capital Theory, Therapeutic Landscapes Theory and Ostrom’s Social-Ecological Systems (SES) Framework. By conducting in-depth interviews with 15 residents, the study reveals that proximity to the ocean decreases stress and anxiety significantly, improves mood, and improves cognitive functioning, which is in line with the Blue Mind Theory and the Biophilia Hypothesis. Habituation effects also decrease emotional benefits for long-term residents, suggesting variability in environmental sensitivity. The study further highlights the physical health advantages of living on the coast, including increased activity through swimming, fishing, and walking. Sleep quality in coastal settlements differs among participants; some residents report the ocean sounds restful, while others report a disturbance. Socially, the beach is a shared space, facilitating bonding through casual meetings and shared labor, following the Social Capital Theory. Moreover, traditional seawater treatments are also prevalent, with residents using them to heal illnesses like stomach disorders and skin conditions, justifying the Therapeutic Landscapes Theory. Despite these benefits, there is conflict between restorative leisure and economic output, with some residents viewing contemplative time as unnecessary and unproductive. The study recommends the integration of blue spaces into public health policy, promoting coastal therapy in mental health care, and further research on seawater treatments.

Our study occurred in a fishing territory under ocean grabbing driven by the Latin America’s largest port, located in São Paulo State, Brazil. To address this context, we adopted a transdisciplinary approach, organizing workshops with fishers to discuss the consequences of overlapping fishing and port territories and conducting interviews with institutional actors to understand their perceptions of the conflict and their roles in local governance. Building on these results, we convened stakeholders in a participatory scenario exercise to design strategies for transforming this reality. The process identified four priority spheres: Negotiation Body, Environmental Licensing, Social Participation, and Regulation of Port Activities, considered essential for change, and for which specific strategies were co-developed to form an action plan. However, this effort was weakened by limited engagement from institutional actors and by the persistent difficulty of establishing a formal governance body. The co-construction process involving multiple stakeholders converged on a shared understanding of the advancement of ocean grabbing. From the perspective of Interactive Governance, the meta-order still struggles to recognize small-scale fisheries and their knowledge. Even so, the research fostered interactions among governance orders and supported the co-construction of a document with fishers as a contribution to second-order environmental licensing processes. We also observed gains, including greater recognition of fishing communities and strengthened engagement among fishers.
