Despite their ecological importance and high abundance, the feeding habits of these fishes have not yet been fully investigated in the Southwest Subtropical Atlantic. We examined spatial variations in the trophic ecology of two lanternfish (Myctophidae: Myctophiformes) species (<em>Gymnoscopelus bolini</em> and <em>Lepidophanes guentheri</em>). The analyses were based on two different regions of the southwest subtropical Atlantic influenced by distinct oceanographic regimes: (a) the north (20–28°S) and (b) south (28–34°S). Stomach content analysis (SCA) revealed that <em>G. bolini</em> preyed mainly on Euphausia spp. and Copepoda (%FO: 18.2), and <em>L. guentheri</em> preyed mainly on Euphausia spp. (%FO: 10.3) and Chaetognatha (%FO: 3.4). Stable isotope analysis (SIA) revealed that L. <em>guentheri</em> had different mean carbon (δ¹³C) and nitrogen (δ¹⁵N) values (± SD) between the north (δ¹³C: −19.9 ± 0.3 ‰; δ¹⁵N: 6.2 ± 0.9 ‰) and south (δ¹³C: −20.5 ± 0.7 ‰; δ¹⁵N: 8.5 ± 2.3 ‰) regions, while <em>G. bolini</em> (south only) had average values of δ¹³C: −20.4 ± 0.6 ‰, δ¹⁵N: 9.6 ± 2.1 ‰. In the southern region, there was similarity between the diets of <em>G. bolini</em> and L. <em>guentheri</em>, and the isotopic niche overlap was also considerable (up to 92.9 %). When comparing the northern and southern regions, there were dietary differences for L. <em>guentheri</em>, as well as significant differences in δ¹³C and δ¹⁵N values (<em>p</em> = 0.002). <em>G. bolini</em> and L. <em>guentheri</em> exhibited a generalist zooplanktivorous feeding behaviour. In addition, region seems to be a determining factor in the trophic ecology of Myctophidae. We hypothesized that the region influence is mainly due to the distinct oceanographic processes that affect primary productivity and the base of the trophic chain.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"207 ","pages":"Article 102614"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144842723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wind forcing field for WW3 is constructed by assimilating wind products from Haiyang-2 (HY-2), the Soil Moisture Active–Passive (SMAP) radiometer and the Advanced Microwave Scanning Radiometer-2 (AMSR2). The model simulated waves during Typhoons Lekima (2019) and Yagi (2024) incorporating sea surface current speed and sea surface level data from the Copernicus Marine Environment Monitoring Service (CMEMS). Validation against HY-2B satellite significant wave height (SWH) measurements demonstrates that the LS17 outperforms other schemes in shallow coastal regions (&lt; 200 m water depth), achieving optimal metric with a root mean square error (RMSE) of 0.5109 m and a correlation coefficient (Cor) of 0.8748. Comparison with buoy reveals maximum SWH discrepancy of 0.3 m between LS17 and BJ78 in shallow waters (i.e., 13 m water depth). This study evaluates the performance of two wave-breaking parameterizations (BJ78 and LS17) in WW3 simulations against HY-2 observations, with a focus on Super Typhoon Yagi (2024). Results indicate that both schemes perform comparably in deep waters (200–80 m depth), showing minimal deviations (∼0.5 m). However, near the coast (80–0 m), BJ78 exhibits significant underestimation (−2 m bias), while LS17 maintains higher accuracy. The superior performance of LS17 in shallow waters underscores the critical role of wave-breaking parameterization selection for reliable nearshore wave modeling, especially during extreme events such as typhoons.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"206 ","pages":"Article 102602"},"PeriodicalIF":2.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research employs fixed-effects models, spatial Durbin models, and mediation effect models. The results show that: First, the digital economy exerts a significant positive effect on enhancing port resilience. Second, improvements in technological innovation capacity, advanced industrial restructuring, and optimized resource allocation efficiency constitute the core mediating pathways through which the digital economy empowers port resilience. Third, regional digital economic development not only boosts local port resilience but also generates positive spatial spillover effects on neighboring areas' port resilience. Fourth, the promoting effect of the digital economy on port resilience remains robust regardless of shock directionality and exhibits a gradient-decreasing pattern across the southern, western, and northern economic zones.
