Fine sediments can enter the receiving environment and have a plethora of potential negative impacts (e.g., ecological, and recreational) and present no real opportunities or positive impacts. In the present study, a Delft3D numerical model is presented. The model has been calibrated considering water levels, currents, temperature, salinity, and Suspended Sediment Concentrations (SSC). Delft3D-Wave was also coupled to the hydrodynamic model to investigate the role of wave related fine sediment resuspension due to wave bed shear stresses. The extent of this model covered the Wairoa River and estuary, just south of Auckland, New Zealand. The motivation for this study was to produce a method that could link the upstream SSC contribution to the subsequent distribution in the receiving environment. From there it can readily be used as input to a regional scale model to investigate and understand the fate of sediments in the Hauraki Strait.

The novelty in this study is reporting unreported genera to be infested with certain disease conditions, further this study demonstrates how surveys in previously poorly studied areas or habitats can reveal important information pertaining to coral diseases, thus helping to fill existing knowledge gaps. Another important aspect of this study is, we provide a review of the distribution of coral diseases within the KMNP based on our results and previous reports. Being a rapid survey, the dynamics of these diseases were not assessed, while the major cause(s) of the diseases remains to be identified. In general, climate change-related aspects including rises in sea surface temperature, as well as other factors such as host density may be responsible for disease prevalences in the region.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Using benthic macroinvertebrate assemblages from <em>Macrocystis pyrifera</em> holdfasts, this study exposes how environmental heterogeneity inside the ISC can also be expressed in biological terms. Four zones were considered in the ISC from north to south (Reloncaví, Chacao, Quinchao, and Quellón), with five sampling sites within them. The spatial variability of macroinvertebrate density, composition, species/taxa richness (S), Shannon´s diversity (H´), and overall beta diversity (β_sor) in 200 kelp holdfasts (<em>n</em> =50 per zone) between zones and sites were analyzed. ANOVA results showed that the holdfast size, zones and sites within zones explained the variability of density, S and H´. Tukey HSD test also indicated significant (<em>p</em> &lt; 0.01) differences between sampling zones and sites. Distribution patterns included: i) a latitudinal increase in density from the north to the centre of the ISC (max. of 67 ind 10 cm⁻², Quinchao); ii) higher S values in the north (max. of 37, Reloncaví); iii) a latitudinal decrease in H´ (max. of 3.2, Reloncaví); iv) lower values for all the ecological attributes in the south (Quellón). Overall beta diversity analysis (β_sor) showed high variability inside each zone, mainly driven by species turnover (β_sim) rather than species nestedness (β_sne). nMDs analysis suggested that the northern zones of ISC can be considered the same and differentiated from the others, but they are highly variable within them. PERMANOVA analysis showed that the macroinvertebrates' composition patterns were significantly (<em>p</em> &lt; 0.01) explained by the holdfast size, and sampling sites/zones. SIMPER analysis revealed the contribution of annelids, arthropods, and molluscs to dissimilarities between zones. The results highlighted the biological heterogeneity of the ISC, suggesting that site-specific environmental conditions affect <em>M. pyrifera</em> populations and, therefore, macroinvertebrates inhabiting their holdfasts.

However, a detailed synthesis of temporal changes on coral reef drivers and ecological responses for the GSUA is still missing. This review addresses these gaps by analyzing trends in both current ecological and anthropogenic drivers and proposing a framework for future research.

Such actions are aimed at enhancing research capacity and mitigating the persistent impacts of urban development and climate change on the reefs.

The semi-enclosed Bohai Sea is home to diverse marine organisms and serves as a critical area for human mariculture. Salinity variations in this region are crucial for the stability of the ecosystem and the sustainability of the marine economy. However, significant discrepancies have been observed between the practical salinity measurements of the Bohai Sea in winter 2007 and that recorded in widely used national and international marine atlases prior to 2000. To identify these discrepancies, this study systematically investigates the salinity variations and the regulatory mechanisms in the Bohai Sea. First, we constructed a climatological salinity dataset with a broader temporal scope based on in-situ salinity data from 1960 to 2020, confirming that the climatological salinity field of the Bohai Sea did not undergo a significant shift, but exhibited phase changes. Subsequently, using the principles of conservation of mass and salinity, we developed a box model to analyze annual salinity changes in the Bohai Sea. This model was optimized using in-situ hydrological measurements and reanalysis data spanning over 60 years, successfully revealing the central regulatory role of local freshwater fluxes in annual salinity changes in the Bohai Sea. Furthermore, we elucidated that the anomalously high salinity in the Bohai Sea in the winter of 2007 resulted from the cumulative effect of several consecutive years of negative freshwater fluxes. The results of this study not only enhance our understanding and prediction of salinity changes in semi-enclosed seas, providing a scientific basis for ecosystem protection and management, but also offer valuable insights for studying long-term salinity changes in other semi-enclosed seas.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142593193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
