This study analyzed structural and compositional responses of both communities to the coupled effects of drying and salinity in two streams and two shallow lakes in Spain, during three hydrological phases: wet, contraction, and dry. In the two studied saline streams, the contraction phase presented the highest aquatic and terrestrial abundance and richness, and the main compositional changes were mainly due, to an increase in aquatic lentic taxa (e.g., Coleoptera), and Araneae and Formicidae as terrestrial taxa. In shallow lakes, which presented highly variable salinity conditions, the highest abundance and diversity values were found at the wet phase for aquatic invertebrates and at the dry phase for terrestrial invertebrates. Compositional invertebrate community changes were due to a decrease in Rotifera and Anostraca (aquatic taxa) in the contraction phase for aquatic communities, and to an increase of Araneae, Coleoptera, and Formicidae (terrestrial taxa) at the dry phase for the terrestrial.

Recently, the trait-based approach has become the center of functional assessment. The trait-based approach can complement structural bioassessment tools and has the advantage of combining ecological features and biological characteristics rather than only the use of a taxonomic-based approach. In the current study, we explored the differential responses of EPT (Ephemeroptera, Plecoptera, and Trichoptera) traits in selected stream sites in the northwestern Rif of Morocco. A Surber sampler with a 500-µm mesh size and dimensions of 20 × 20 cm was used to collect EPT samples at the sites. Physicochemical and hydromorphological parameters, including temperature, pH, BOD<sub>5</sub>, NO<sub>-3</sub>, Cl<sup>−</sup>, depth, and current velocity, were used to characterize the water quality of the sampled sites. We used 54 trait modalities belonging to 11 trait classes to describe the collected EPT at the family level. We conducted RLQ model and fourth-corner test to examine the interaction between the EPT traits assemblage and habitat predictors at the 36 sampled sites along the stretch of the study area. The RLQ ordination revealed that the distribution patterns of EPT traits differed significantly over the 36 sites. Thus, we expected that the EPT traits assemblage would reflect the degree of the detected environmental pressures. The RLQ model indicated that elevated nutrient levels and conductivity were the key factors explaining most of the variability in functional traits at the downstream sampled sites. EPT traits such as life cycle duration, food preferences, maximal potential size, and substrate preference were positively associated with sites exhibiting notable deterioration. Baetidae and Leptophlebidae in S2, S3, and S20 favored these trait assemblages.

One hundred eighteen different taxa were observed, of which 30 were algae, mainly red, and the most predominant were polychaetes, arthropods, and sipunculids, with a significant prevalence of polychaetes and arthropods at the north. Arthropods and polychaetes were more abundant in the shallower samples, while sipunculids were only found in the deeper ones.

However, the risk of lake eutrophication is dependent upon inherent lake system characteristics and ecological behaviour. To be able to account for all the varying factors that drive changes in lake systems, a classification scheme that can assign levels of lake resilience (or sensitivity) to change is required. For most lakes around the world there is a lack of data to apply such an approach, with profound implications on the ability to map, monitor and understand regional and global lake behaviour in response to climate change, land use/land management and further disturbance pressures. In this study, lake eutrophication risk was assessed using a typology-based approach developed using remotely sensed, modelled and open access datasets from 738 lakes and their catchments worldwide. The new framework classifies lakes according to (i) their natural sensitivity to eutrophication and, by extension, (ii) their resilience to external pressures. Support for the approach is evidenced from independent space-based water quality assessment illustrating that lakes with higher risk of eutrophication typically exhibit higher chlorophyll-a concentrations. Whilst other classifications schemes exist, the novelty of the proposed approach is that it combines explanatory variables (ten lake and catchment metrics) to develop a framework with global applicability. Results showed that 93% of the study sites exhibited low-to-moderate risk of the catchment on the water body in terms of accelerating or slowing down nutrient loading, whereas 6% of the study sites exhibited high sensitivity to such external influence, i.e. risk potential for having high rates of eutrophication. Knowing the rate at which each water body is expected to, or could become, more eutrophic provides a frame of reference in the prediction of the effect of human pressures and climate change on lake systems, both now and in the future. Targeted monitoring of more sensitive lakes can ensure that early warning signs of potentially irreversible or damaging water body change will not be missed. This global risk eutrophication assessment framework can, therefore, help to better safeguard, manage and protect freshwater resources for future societal and ecosystem wellbeing and sustainable economic growth.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"86 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311862","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}

Traditionally, the trophic state has been assessed using the Trophic State Index (TSI), but recently, chromophoric dissolved organic matter (CDOM) has emerged as a new indicator of eutrophication. We conducted a 2-year seasonal survey in three interconnected Andean-Patagonian lakes (Argentina), with different hydrogeomorphic features and macrophyte cover, considering both low-water (LWP) and high-water (HWP) phases. We aimed to determine the influence of WLFs and macrophyte cover on TSI dynamics, and to evaluate the use of CDOM for monitoring the trophic state of these Andean-Patagonian lakes. TSI ranged from ultraoligotrophy to mesotrophy and showed significant changes between rainy and dry seasons, particularly in shallow lakes. WLFs were revealed to be an important regulatory factor in this connected system, since a pronounced differentiation of physicochemical variables was found among lakes during the LWP, and homogenization during the HWP. Submerged macrophytes strongly affected nutrient dynamics, especially nitrogen (N), and consequently TSI. During the LWP, nutrient release associated with macrophyte senescence resulted in elevated TSI values in the shallowest lake. During periods of macrophyte growth and higher hydrological connectivity, a dilution effect developed, with reduced TSI values. Strong positive correlations found between TSI and CDOM (a<sub>254</sub>) highlighted CDOM as a reliable indicator of TSI, even in ultra-oligotrophic lakes.
