Coastal wetlands face severe degradation, especially in developing deltas where economic growth conflicts with conservation. This study addresses two critical gaps: oversimplified resistance models and limited dynamic connectivity assessments under combined natural-human pressures and makes two key advances: (1) an innovative “landscape-vegetation-soil” framework integrating multi-source data to model Habitat Suitability Index (HSI) and construct refined resistance surfaces; (2) multi-temporal ecological networks using Minimal Cumulative Resistance (MCR) and gravity models to quantify connectivity dynamics in China's Yellow River Delta. Results reveal a “core degradation-peripheral shrinkage” pattern in the ecological network, driven by intensive urbanization and aquaculture expansion. While most counties exhibited a post-2010 recovery trend in HSI, Hekou District diverged with persistent degradation. Crucially, vegetation vitality emerged as the dominant driver of ecosystem resilience, supported by an obvious NPP (net primary production)-SOC (soil organic carbon) feedback mechanism that underscores the pivotal role of vegetation restoration. Methodologically, we advance ecological network analysis through HSI modeling integrating remote sensing and field-validated data and dynamic resistance surface construction capturing 30-year anthropogenic impacts. We propose a three-tiered strategy prioritizing: (1) Core sources protection; (2) Critical corridors rehabilitation; (3) Multi-scale governance integrating county-specific policies. This study provides both theoretical foundations for deltaic ecosystem management and practical tools for coastal conservation, with global applications for vulnerable land-sea interfaces. The integrated framework offers novel solutions for balancing ecological integrity with socioeconomic needs in rapidly developing deltas.

沿海湿地面临着严重的退化，特别是在发展中的三角洲，那里的经济增长与保护相冲突。该研究解决了自然-人类联合压力下过度简化的抗性模型和有限的动态连通性评估这两个关键缺陷，并取得了两个关键进展：(1)创新的“景观-植被-土壤”框架，整合多源数据来模拟生境适宜性指数（HSI）并构建精细的抗性面；(2)基于最小累积阻力（MCR）和重力模型的黄河三角洲时空生态网络连通性动态量化研究。结果表明，在集约化城市化和水产养殖扩张的驱动下，生态网络呈现“核心退化-外围萎缩”的格局。2010年后，大多数县区的HSI均呈现恢复趋势，而河口区则表现出分化和持续退化。重要的是，植被活力成为生态系统恢复力的主要驱动力，并得到了明显的NPP（净初级生产）-SOC（土壤有机碳）反馈机制的支持，强调了植被恢复的关键作用。在方法上，我们通过整合遥感和实地验证数据的HSI模型和捕捉30年人为影响的动态阻力面构建，推进生态网络分析。我们提出了一个三层战略优先顺序：(1)核心资源保护；(2)危重廊道修复；(3)因地制宜的多尺度治理。该研究为三角洲生态系统管理提供了理论基础，也为海岸保护提供了实用工具，并在全球范围内应用于脆弱的陆海界面。综合框架为平衡快速发展的三角洲的生态完整性和社会经济需求提供了新的解决方案。

Marine trade, as a vital growth point for sustainable ocean-based economy, offers a critical pathway for achieving sustainable development goals (SDGs). Inclusive green growth (IGG) has become widely recognized as an important indicator to measure a country's progress toward SDGs. However, the mechanisms through which marine trade influences national IGG, as well as the varying degrees of its impact across countries, remain insufficiently understood. Anchored in the frameworks of blue growth and blue justice, this study constructs a theoretical model integrating factor integration, operational efficiency, and green low-carbon transition. Based on this framework, this study quantified marine trade in 62 representative countries and analyzed its impact on IGG through both theoretical and empirical according to the UNCTAD classification of sustainable ocean-based economy. The results revealed that the relationship between the scale of marine trade and national IGG follows a positive N-shaped curve. Furthermore, heterogeneity analysis indicated that marginal increases in marine trade have a more pronounced impact on IGG in African countries. These findings suggest that marine trade functions not only as an economic driver, but also as a governance mechanism that shapes ecological sustainability, institutional equity, and social inclusion. The study provides important insights for enhancing trade cooperation among leading maritime economies and informing policy design in developing countries with smaller markets and remote geographies. Ultimately, these findings advance global efforts toward achieving SDGs and fostering resilient ocean-based economies.

海洋贸易作为可持续海洋经济的重要增长点，是实现可持续发展目标的重要途径。包容性绿色增长（IGG）已被广泛认为是衡量一个国家实现可持续发展目标进展的重要指标。然而，海洋贸易影响国家免疫球蛋白组的机制，以及其对各国不同程度的影响，仍然没有得到充分的了解。本研究立足于蓝色增长和蓝色正义的框架，构建了要素整合、运营效率和绿色低碳转型的理论模型。在此框架下，本研究根据UNCTAD对可持续海洋经济的分类，对62个代表性国家的海洋贸易进行量化，并从理论和实证两方面分析其对IGG的影响。结果表明，海洋贸易规模与国家IGG之间呈正n型关系。此外，异质性分析表明，海洋贸易的边际增长对非洲国家免疫球蛋白g的影响更为显著。这些发现表明，海洋贸易不仅具有经济驱动作用，而且还具有形成生态可持续性、制度公平和社会包容的治理机制。该研究为加强主要海洋经济体之间的贸易合作以及为市场较小和地理位置偏远的发展中国家的政策设计提供了重要见解。最终，这些发现将推动全球努力实现可持续发展目标，并培育具有复原力的海洋经济。

Coastal cities increasingly face compound flooding risks due to sea-level rise and intensifying storms. This study systematically evaluates the synergistic regulation of coastal hydrodynamics by mangrove vegetation and intertidal topography as a nature-based solution (NbS) for coastal defense. Based on the Delft3D Flexible Mesh (FM) system, we simulate tidal and storm surge scenarios in two contrasting shorelines in Shenzhen, China, the naturally evolved Xiwan Mangrove Park and the engineered Bao'an Airport coastline. Results show that intertidal topography plays a dominant role in attenuating flow velocity, while mangrove vegetation becomes the primary factor in reducing peak water levels during extreme events. A functional shift in mitigation zones occurs, from mid and low tidal flats under tidal conditions to high flats during storm surges, driven by increased inundation and canopy engagement. Additionally, a clear design threshold of 600 m planting width is identified, beyond which additional vegetation provides diminishing returns due to the complete submergence of mangrove vegetation. These findings underscore the complementary roles of topography and vegetation and offer actionable guidance for optimizing NbS strategies in site-specific, climate-adaptive coastal management.

由于海平面上升和风暴加剧，沿海城市越来越多地面临复合洪水风险。本研究系统评估了红树林植被和潮间带地形对海岸水动力的协同调节，作为一种基于自然的海防解决方案。基于Delft3D柔性网格（FM）系统，我们模拟了中国深圳两个截然不同的海岸线——自然演变的西湾红树林公园和工程建设的宝安机场海岸线——的潮汐和风暴潮情景。结果表明，潮间带地形在减缓极端事件期间的流速中起主导作用，而红树林植被在减缓极端事件期间的峰值水位中起主要作用。由于洪水和冠层接触增加，减缓区的功能发生了转变，从潮汐条件下的中低潮滩向风暴潮期间的高潮滩转变。此外，还确定了600米种植宽度的明确设计阈值，超过这个阈值，由于红树林植被完全淹没，额外的植被带来的收益会递减。这些发现强调了地形和植被的互补作用，并为优化NbS策略在特定地点的气候适应性沿海管理中提供了可操作的指导。

California is striving to expand its ‘blue economy’ to meet growing demand for marine resources, including seafood and renewable energy. As a result, there has been a growing competition for ocean space. Co-location, multiple sectors (e.g., aquaculture and renewable energy) operating in the same ocean space at the same time, is one potential approach that can reduce competition amongst stakeholders. However, there has been limited quantitative investigation into the potential of co-located systems along the California coast. Using a combination of observation and model outputs across four ocean sectors (aquaculture, wave energy, wind energy and wild capture fisheries), we quantify the co-location suitability of at least two of the sectors along the California coast (0.0404° resolution) by calculating a Co-location Suitability (CLS) score (0 – no suitability to 1 – perfect suitability). We find a clear trend of higher CLS scores in the waters offshore of Northern California, but the steep bathymetry limits the potential for aquaculture and wave production based on current technological and/or cost constraints. Notably, we find climate extreme thermal events, (i.e., marine heatwaves) will likely exacerbate regional differences in suitability with typically cooler Northern regions performing better. This research provides an initial framework for evaluating co-location potential and its ability to increase the efficiency of marine space-use in crowded seascapes in California waters and beyond.

加州正在努力扩大其“蓝色经济”，以满足对海洋资源日益增长的需求，包括海产品和可再生能源。因此，对海洋空间的竞争日益激烈。同一地点，即多个部门（如水产养殖和可再生能源）同时在同一海洋空间经营，是一种可以减少利益攸关方之间竞争的潜在方法。然而，对加州海岸共址系统的潜力进行了有限的定量调查。结合四个海洋部门（水产养殖、波浪能、风能和野生捕捞渔业）的观测和模型输出，我们通过计算共定位适宜性（CLS）得分（0 -不适宜性到1 -完美适宜性），量化了加利福尼亚海岸至少两个部门的共定位适宜性（0.0404°分辨率）。我们发现，在北加州近海水域，CLS得分明显上升，但由于目前的技术和/或成本限制，陡峭的水深限制了水产养殖和波浪生产的潜力。值得注意的是，我们发现气候极端热事件（即海洋热浪）可能会加剧适合性的区域差异，通常较冷的北方地区表现更好。这项研究提供了一个初步的框架，用于评估共同定位的潜力及其在加利福尼亚水域和其他地区拥挤的海景中提高海洋空间利用效率的能力。

Bycatch threatens albatrosses and petrels, prompting all tuna Regional Fisheries Management Organizations to require bycatch mitigation measures in areas overlapping high seabird densities. In the Southern Hemisphere, and with one exception of the IATTC, tuna longliners south of 25°S in Indian and Atlantic oceans and south of 30°S in western Pacific Ocean must use at least two of the following three measures: night setting, bird-scaring lines, and branch line weighting. Adding weights is complex, and carries concerns about negative impacts on target species catch rates and crew safety. From 2013 to 2016, we tested the effects of Lumo Lead® on seabird bycatch, target catch rates, and safety aboard seven Korean tuna longliners. Trials involved 358,649 unweighted and 468,476 weighted lines (40–60 g, 0–200 cm from the hook) across 483 sets. The seabird bycatch rate in weighted branch lines was significantly lower than that in unweighted branch lines (p < 0.001). There was no difference in catch rate when targeting southern bluefin tuna (Thunnus maccoyii) and a slight difference for yellowfin tuna (T. albacares). The catch rate of albacore tuna (T. alalunga, ALB) on weighted branch lines was significantly lower (p < 0.001). No safety incidents were reported during the experiment. The reduced ALB catch rate may reflect fishermen's inexperience with line weighting, but this requires further investigation.s. Results suggest the Lumo leads are a safe, effective seabird mitigation measure for Korean longliners but line weighting alone cannot eliminate bycatch and should be used with bird-scaring lines or night setting. More broadly, these findings provide lessons for pelagic longline fisheries globally, showing that safe and practical line weighting can be integrated into existing operations to support sustainable fisheries management and seabird conservation.

副渔获物威胁到信天翁和海燕，促使所有金枪鱼区域渔业管理组织要求在海鸟密度高的重叠地区采取减轻副渔获物的措施。在南半球，除了IATTC的一个例外，印度洋和大西洋南纬25度以南以及西太平洋南纬30度以南的金枪鱼延绳钓必须使用以下三种措施中的至少两种：夜间设置，鸟类惊吓线和分支线称重。增加重量是复杂的，而且会对目标物种的捕获率和船员安全产生负面影响。从2013年到2016年，我们在7艘韩国金枪鱼延绳钓船上测试了Lumo Lead®对海鸟副渔获物、目标渔获率和安全性的影响。试验涉及483组的358,649条未加重线和468,476条加重线（40-60克，距鱼钩0-200厘米）。加权支线副渔获率显著低于未加权支线（p < 0.001）。以南方蓝鳍金枪鱼（Thunnus maccoyii）为目标时，捕获率没有差异，而黄鳍金枪鱼（T. albacares）略有差异。长鳍金枪鱼（T. alalunga， ALB）在加权支线上的捕捞率显著降低（p < 0.001）。实验过程中未发生安全事故。ALB捕获率的下降可能反映了渔民对鱼线称重缺乏经验，但这需要进一步调查。结果表明，对于韩国延绳钓者来说，Lumo引线是一种安全、有效的减少海鸟的措施，但单独加重线并不能消除副渔获，应与吓鸟线或夜间设置一起使用。更广泛地说，这些发现为全球远洋延绳钓渔业提供了经验教训，表明可以将安全和实用的延绳钓加权纳入现有作业，以支持可持续渔业管理和海鸟保护。

Maritime traffic poses a variety of risks to both the marine environment and marine wildlife. To quantify and predict risk, accurate data on the distribution and densities of vessel traffic is required, yet currently there is no single data type that captures all vessel traffic. Most commonly, AIS (Automatic Identification System) vessel tracking data is used, despite awareness that AIS data does not fully capture all vessels present. Therefore, evaluations using only AIS likely underestimate the potential impacts. To estimate the scale of underestimation, vessel presence within six of Scotland's Marine Protected Areas (MPAs) were recorded during >1800 h of land-based and at-sea surveys, and compared with AIS data collected from a network of receivers deployed around Scotland. Non-AIS vessels were present within MPAs during 62 % of the surveyed period, with 64 % of vessels sighted not broadcasting AIS. AIS transmission rates varied between MPA, season and vessel type. Given that AIS data is the most commonly used data type for quantifying vessel activity and predicting associated impacts, consideration must be given to the volume of vessel traffic not represented within AIS datasets, particularly within MPAs. Underestimation of actual vessel traffic is likely leading to insufficient management or mitigation efforts within areas designated for protection.

海上交通给海洋环境和海洋野生动物带来了各种风险。为了量化和预测风险，需要关于船舶交通分布和密度的准确数据，但目前还没有一种单一的数据类型可以捕获所有船舶交通。最常见的是使用AIS（自动识别系统）船舶跟踪数据，尽管人们意识到AIS数据并不能完全捕获所有存在的船舶。因此，仅使用AIS的评估可能低估了潜在的影响。为了估计低估的程度，在1800小时的陆上和海上调查期间，记录了苏格兰六个海洋保护区（MPAs）内的船只存在情况，并与部署在苏格兰周围的接收器网络收集的AIS数据进行了比较。在62%的调查期间，非AIS船只出现在海洋保护区内，64%的船只被发现没有广播AIS。AIS的传播率因MPA、季节和船型而异。鉴于AIS数据是量化船舶活动和预测相关影响最常用的数据类型，必须考虑AIS数据集中未表示的船舶交通量，特别是在海洋保护区内。对实际船舶交通的低估很可能导致指定保护区域内的管理或缓解努力不足。

This study delves into the trophic interaction of two Sciaenidae fish, Larimichthys polyactis and Collichthys lucidus, within marine ranching and adjacent habitats (artificial reef area, comprehensive effect area and estuary area) in Haizhou Bay, China, utilizing stable isotope analysis. Isotopic analyses revealed significant differences in δ¹³C and δ¹⁵N values of the two species in artificial reef area (P < 0.05). Their isotopic niches exhibited minimal overlap in artificial reef area, substantial overlap in comprehensive effect area, and no overlap in estuary area. Dietary source analysis indicated fluctuating proportions of diet contributions for L. polyactis across habitats, contrasting with relatively consistent proportions for C. lucidus. Connectivity analyses highlighted L. polyactis' higher bidirectional connectivity values between estuary area and comprehensive effect area, while C. lucidus demonstrated elevated bidirectional connectivity values between estuary area and artificial reef area. Moreover, L. polyactis exhibited greater connectivity to comprehensive effect area, suggesting a higher dependency, while C. lucidus showcased a stronger reliance on artificial reef area. Furthermore, as temperature and salinity increased, connectivity for both species tended to rise, contrasting with current speed trends. Depth and distance from the coastline influenced connectivity dynamics differently for L. polyactis and C. lucidus. We posit that consolidating consumers' dietary sources can enhance the accuracy of quantifying habitat connectivity, emphasizing that the quantity and types of dietary sources significantly impact quantitative connectivity outcomes. To enhance precision, we advocate for comprehensive isotopic data collection from all food web consumers. Establishing quantified baseline values will be instrumental in evaluating habitat connectivity. The findings in this study will provide valuable insights for prompting the ecological effect of marine ranching and implementing the stock enhancement activities in coastal water in the future.

利用稳定同位素分析方法，研究了海州湾海洋牧场及其邻近生境（人工鱼礁区、综合效应区和河口区）中两种鱼科鱼科鱼（Larimichthys polyactis和Collichthys lucidus）的营养相互作用。同位素分析显示，两种鱼在人工鱼礁区δ13C和δ15N值差异显著（P < 0.05）。其同位素生态位在人工鱼礁区重叠最小，在综合效应区重叠较大，而在河口区没有重叠。饲料来源分析表明，在不同生境中，多聚乳杆菌的饲料贡献比例波动较大，而透明乳杆菌的饲料贡献比例相对稳定。连通性分析表明，L. polyactis在河口区与综合效应区之间的双向连通性值较高，C. lucidus在河口区与人工礁区之间的双向连通性值较高。此外，聚藻对综合效应区域的连通性更强，表明其对人工鱼礁区域的依赖性更高，而绿藻对人工鱼礁区域的依赖性更强。此外，随着温度和盐度的增加，这两个物种的连通性倾向于上升，与目前的速度趋势相反。距离海岸线的深度和距离对水蛭和水蛭连通性动态的影响不同。我们认为，整合消费者的饮食来源可以提高量化栖息地连通性的准确性，并强调饮食来源的数量和类型显著影响定量连通性的结果。为了提高准确性，我们提倡对所有食品网消费者进行全面的同位素数据收集。建立量化的基线值将有助于评估生境连通性。本研究结果将为今后提高海洋牧场的生态效应和实施沿海水域的种群增加活动提供有价值的见解。

Cinderella effects in conservation assessment: Re-evaluating biodiversity merit in a South African estuarine system 保护评估中的灰姑娘效应：重新评估南非河口系统的生物多样性价值

Two adjacent estuaries in South Africa differ markedly in their assessed biodiversity, conservation status and management style: one, a flagship site, is considered to support the richest estuarine biodiversity in the country, receives the management and protection of a National Park, and attracts much research attention; the other is regarded as having an impoverished macrobenthic fauna, bears no formal conservation status, and is much less studied. To test whether these supposed contrasts in biodiversity are simply a reflection of differential levels of scientific attention, the biodiversity, abundance and nature of the macrobenthos in a representative habitat, beds of the endangered seagrass Nanozostera capensis that dominate both estuaries, were compared in apparently equivalent upstream (estuarine and lagoonal) locations of the two systems using identical field research effort and methodology. There the neglected and supposed impoverished estuary (the Keurbooms/Bitou) was found to support as great, if not greater, macrobenthic biodiversity, in greater abundance, and with more numerous rare endemics than the flagship conservation site (the Knysna estuarine bay). Its previously considered species poverty appears entirely due to inadequate earlier investigation, particularly in respect of its invertebrate fauna. Of the two, Keurbooms/Bitou also has the merit of being less accessible and less anthropogenically impacted. This study highlights the consequences of basing conservation assessments on incomplete biodiversity data, and stresses that a uniform programme of investigative fieldwork is critical for the meaningful ranking of sites. It also emphasises the extent to which non-bait species of invertebrate are often ignored in estuarine management protocols to the detriment of local and overall conservation management aims.

南非两个相邻的河口在评估的生物多样性、保护状况和管理方式上存在显著差异：一个是旗舰地点，被认为支持该国最丰富的河口生物多样性，受到国家公园的管理和保护，并吸引了许多研究关注；另一种被认为是大型底栖动物贫乏，没有正式的保护地位，研究也少得多。为了检验这些生物多样性的假设差异是否仅仅是科学关注水平的不同反映，我们使用相同的实地研究工作和方法，在两个系统明显相同的上游（河口和泻湖）位置，比较了代表性栖息地（濒危海草Nanozostera capensis床）中大型底栖动物的生物多样性、丰度和性质。在那里，被忽视和被认为贫瘠的河口（keurboom /Bitou）被发现与旗舰保护地点（Knysna河口湾）相比，拥有更丰富的大型底栖生物多样性和更多的稀有特有物种，如果不是更大的话。其先前认为的物种贫乏似乎完全是由于早期调查不足，特别是在其无脊椎动物群方面。在这两者中，keurboom /Bitou还有一个优点，那就是交通不便，受到的人为影响较小。这项研究强调了以不完整的生物多样性数据为基础进行保护评估的后果，并强调了统一的调查实地工作方案对于有意义的地点排名至关重要。它还强调了在河口管理协议中经常忽视非诱饵无脊椎动物物种的程度，从而损害了当地和整体保护管理目标。

To support coastal practitioners and decision makers manage the complex coastal zone a structured framework was developed to navigate a range of technologies, datasets and data-derived products based on their suitability to monitor the spatial and temporal diversity of coastal processes and morphological indicators. Remote piloted aircraft (RPA) fitted with a LiDAR sensor was used in conjunction with airborne LiDAR and photogrammetry data to undertake foredune change analyses for selected sites in southeastern Australia to validate and demonstrate optimal technology for coastal monitoring. Results were compared with satellite derived coastal change products, including the Digital Earth Australia Coastlines and CoastSat. Foredune volumes from the mid-1900s to 2024 at the highly modified and urbanised Woonona-Bellambi and Warilla Beaches exhibited long-term stability interrupted by large storm events and anthropogenic interventions. Satellite derived data from 1988 onwards showed shoreline regions experiencing the highest rates of seaward extension and landward retreat. The high temporal resolution of this data supports monitoring changes, such as the influence of the El Niño Southern Oscillation on beach rotation. Photogrammetry data with multidecadal temporal coverage provides insights into historical changes. Airborne LiDAR offers three-dimensional data with high spatial resolution to develop accurate terrain models as LiDAR pulses can penetrate foredune vegetation. RPA LiDAR and aerial image data delivered the highest spatial resolution of the beach and foredune region and improves capacity to understand and describe sediment dynamics within a beach or compartment. Rapid deployment capability of RPAs allows for immediate evaluation of impacts from episodic events including storms and management interventions, thereby enhancing hazard mitigation efforts, and improving knowledge of coastal processes. The framework presented in this study emphasises the importance of integrating complimentary monitoring technologies and datasets to improve the temporal and spatial relevance of projections that inform coastal management.

为了支持沿海从业者和决策者管理复杂的海岸带，研究人员开发了一个结构化框架，根据一系列技术、数据集和数据衍生产品的适用性来监测沿海过程和形态指标的时空多样性。安装了激光雷达传感器的遥控飞机（RPA）与机载激光雷达和摄影测量数据结合使用，对澳大利亚东南部选定的地点进行沙丘变化分析，以验证和演示海岸监测的最佳技术。结果与卫星衍生的海岸变化产品进行了比较，包括数字地球澳大利亚海岸线和海岸卫星。从20世纪中期到2024年，高度改造和城市化的Woonona-Bellambi和Warilla海滩的前丘体积表现出长期的稳定性，被大型风暴事件和人为干预所中断。从1988年以来的卫星数据显示，海岸线地区经历了向海延伸和向陆地退缩的最高速率。这些数据的高时间分辨率支持监测变化，例如厄尔Niño南方涛动对海滩旋转的影响。具有多年代际时间覆盖的摄影测量数据提供了对历史变化的见解。机载激光雷达提供高空间分辨率的三维数据，以建立精确的地形模型，因为激光雷达脉冲可以穿透沙丘前植被。RPA激光雷达和航空图像数据提供了海滩和前丘区域的最高空间分辨率，提高了理解和描述海滩或隔室内沉积物动态的能力。区域保护区的快速部署能力可以立即评估包括风暴在内的偶发事件和管理干预措施的影响，从而加强减灾工作，并提高对沿海过程的认识。本研究提出的框架强调了整合互补监测技术和数据集的重要性，以改善为沿海管理提供信息的预测的时间和空间相关性。
