Satellite remote sensing techniques were used for mapping the seagrass <i>Cymodocea nodosa</i> (Ucria) Asch, which presents an extensive expansion in the study area. The results showed that Klisova is a hypersaline, well-oxygenated lagoon presenting changes in temperature, salinity, pH and dissolved oxygen over the course of 1 year, but largely lacks any spatial differentiation other than an east–west gradient in salinity in spring and summer. Sediment was classified as silty sand to silt, rich in total organic carbon (TOC), total nitrogen (TN) and total phosphorus (TP). The benthic community was characterised by a high species richness and the presence of marine species, without a clear spatial pattern. The multivariate-AZTI’s marine biotic index (M-AMBI) showed that the ecological quality of the macrobenthos was good in most stations. <i>C. nodosa</i> covered over 70% of the lagoon area and formed meadows even in the eastern part of the lagoon where salinity during spring and summer was close to the reported upper tolerance limit of the species (&gt; 50).

Internal P loading can alter nutrient availability and limitation supporting HCBs but is rarely quantified or compared with external loads. We have quantified external P loads from 2019 to 2021 for the three main tributaries (accounting for 46% of the flow) and internal loadings using two methods: a P mass balance and modeled release rates of soluble reactive phosphorus from oxic and anoxic sediments. In addition, we combined high-frequency in situ measurements of water temperature and dissolved oxygen, discrete grab sampling for nutrient chemistry, and remote sensing to explore the potential drivers of the observed variability and provide a comprehensive view of the spatiotemporal dynamics of HCBs. By understanding the relative contribution of external and internal nutrient loadings and the relationship between environmental parameters and HCBs, interannual bloom variability can be better predicted. Comparative estimates of external and internal phosphorus loading indicate that internal sources accounted for 70–95% of the total P input into the system during the study period. Contrary to other lakes, the intensity of the summer bloom season was correlated to the timing and duration of anoxia rather than the magnitude of spring runoff. Internally released P shifted the system from phosphorus to nitrogen limitation during the summer, potentially favoring the proliferation of nitrogen-fixing cyanobacteria.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00027-024-01045-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140129145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

The methodology included the following steps: (1) obtaining water surface time-series data for each coastal municipality and considering hydroclimatic and anthropogenic variables, followed by spatiotemporal analysis using geographic information systems (GIS); (2) conducting analyses of the environmental and physiographic features of the coastal basins; and (3) performing statistical integration and data modeling to test for potential correlations that explain water surface variations.

The aim of this review is to analyse scientific publications, reports, and online documents on mangroves for the entire Maldivian archipelago to provide the first comprehensive summary of the current state of knowledge of mangroves from a national perspective. This includes the geographical location of mangrove forests, the identity and distribution of mangrove species, ecosystem services, ecological importance and diversity of mangrove-associated flora and fauna. We analysed available information from both the grey literature and scientific publications and found that 14 mangrove species have been documented on 108 islands (9% of all Maldivian islands). Mangroves are mainly concentrated in northern atolls and are associated with diverse flora and fauna. Furthermore, we identified inconsistencies and gaps in the literature and proposed future directions for research.

We used <i>Andesiops peruvianus</i> (Ephemeroptera) and <i>Anomalocosmoecus illiesi</i> (Trichoptera), two abundant species in Andean rivers in Ecuador.

The single effect of increasing temperature produced an increase in algal biomass. Positive synergistic effects on chlorophyll-<i>a</i> biomass resulted in ambient chambers with a mix of N+P addition and a combination of +2.5 °C with +P and N+P. The single and interactive effects of nutrient addition and warming water produced high mortality for <i>Andesiops peruvianus</i> but did not impact the survival of <i>Anomalocosmoecus illiesi</i> larvae. The growth rates of <i>Andesiops peruvianus</i> larvae showed no significant effect in any treatments except for the ambient NP treatment, in which we observed a marginal impact on body mass. In turn, the growth rates of <i>Anomalocosmoecus illiesi</i> larvae increased significantly only at +2.5 °C with +P addition.

The analyzed temporal series includes two important events (volcanic eruption and glacial recession) that substantially affected lake turbidity. Thus, our mechanistic model was constructed as a function of changes in the light extinction coefficient (Kd_PAR) and the mean irradiance of the mixing layer (I_m). Our modeling approach using Bayesian inference and a continuous nonmonotonic function successfully predicted changes in Pcy vertical distribution. The model was successful in fitting data for different minerogenic particles (volcanic ash and glacial clay) and in predicting changes under sharp increases in turbidity (volcanic eruptions), as well as in more gradual changes (glacial recession). Pcy maximum abundance increased with transparency (lower Kd_PAR values), and the amplitude of the vertical profile increased with higher I_m values. Using our model, we achieved a full prediction of Pcy vertical distribution under different scenarios of lake transparency and lake thermal structures.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

However, these modern methods were applied in a comparatively limited number of cases. We hypothesize that: (1) proportions of incorporation of organic carbon of leaf litter by benthic consumers can be higher in spring than in autumn due to conditioning of the leaves during winter, and (2) carbon of leaf litter of certain tree species can be incorporated in river food webs to a higher degree than carbon of other tree species. Using SIA, FA, and C:N, allochthonous and autochthonous sources of organic matter and their quality in food webs of a small forest river in the Russian Far East were studied. It was found that some benthic animals obtained organic carbon mainly or exclusively from the allochthonous basal source, leaf litter. The other animals relied heavily or exclusively on the autochthonous basal source of organic carbon, periphytic microalgae, but some of them shifted to the conditioned leaf litter as the principal basal source in spring. Leaves of one of the tree species, Manchurian alder, appeared to be significantly more valuable food for primary consumers than leaves of the other studied species.

We hypothesized that different diatom functional guilds (high-profile, low-profile, motile and planktic) would respond differently to environmental and spatial variables, depending on their mode of attachment and dispersal ability. Guilds showed distinct distributional patterns along a gradient of wave-induced disturbance: low-profile diatoms dominated in exposed shorelines (high disturbance), whereas high-profile and motile diatoms were more abundant in coastal wetlands (low disturbance). Redundancy analysis with variation partitioning of the entire diatom community revealed that environmental variables (littoral geomorphology and water chemistry) outperformed spatial variables, indicating a predominant role of species sorting. When the diatom community was deconstructed into functional groups, benthic guilds (i.e., low-profile, high-profile and motile) showed higher dependence on environmental factors, whereas the planktic guild was primarily predicted by spatial factors. Thus, benthic taxa with lower dispersal abilities were less impacted by mass effects than planktic taxa. Among benthic guilds, motile diatoms were less sensitive to water chemistry compared to low-profile and high-profile diatoms, suggesting that a group-specific habitat preference may interfere with diatom responses to water quality changes. Hence, the response of diatom guilds to water quality parameters was related to their resistance to wave action. Overall, we concluded that the higher importance of environmental filtering than dispersal-related processes in shaping the diatom metacommunity resulted from a combination of a strong environmental gradient in geomorphology/water chemistry and the intermediate spatial scale of our study.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00027-024-01055-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140017459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Ice break-up led to complex hydrodynamics that persisted for nearly 28 days following full ice-off.
