Special Issue Information

Dear Colleagues,

Transitional water ecosystems are defined by the European Union (EU) Water Framework Directive (WFD, CE 2000/60) as “bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal water, but which are substantially influenced by freshwater flows”. When considering Mediterranean coastal lagoons, the former classification of coastal lagoons in transitional waters and coastal waters on the basis of freshwater influence is no longer suitable. Recent literature proposed aligning the administrative and natural boundaries by division into two homogeneous groups of lagoons: Mediterranean lagoons (Mediterranean climate, hot summer, dry season, nanotidal range) and Northern Adriatic lagoons (humid subtropical climate, microtidal range).

Various dynamic coastal ecosystems and management contexts exist, offering different points of view regarding the development of innovative strategies for coastal monitoring management. The monitoring phase is routinely followed by an environmental assessment as a necessary step in the decision-making process.

This Special Issue of JMSE aims to present the most innovative and infomative tools related to Mediterranean coastal lagoon monitoring. The sampling step is taken into account, including, but not limited to, the use of Unmanned Aerial Vehicles for coastal monitoring and methods for collecting samples from difficult-to-access sites. Achieved information will allow the selection of specific variables that could highlight ecosystem changes in advance, contributing to the development of wider monitoring programs in lagoon ecosystems that allow early detection of the evolution of the ecosystem towards eutrophication or the occurrence of dystrophic crises.

Dissolved oxygen (DO) is a key element for the survival of marine organisms and is a supporting element in the current Water Framework Directive (WFD). DO deficiency is a common event that occurs in coastal environments such as estuaries and lagoons, but a long-term DO database that helps detect daily and seasonal oscillations is difficult to obtain with commonly used sampling and analytical procedures. In this work, a network of multi-parametric probes was deployed in the Marano and Grado Lagoon (northern Adriatic Sea, Italy) in order to obtain a dataset from the continuous monitoring of DO and complementary parameters. DO showed a high degree of variability both in terms of spatial and seasonal distribution and was dependent on solar radiation and water temperature. During the summer and in areas characterised by scarce water renewal, DO was below the threshold set as the minimum requirement for aquatic life, thus some water bodies (WBs) were classified as moderate sensu WFD. The inputs of freshwater discharge from inland and marine waters during tides are, however, able to well oxygenate most of the lagoon. These results will be useful in supporting the management and protection of this vulnerable environment. Full article

The Vaccarès Lagoon System, located in the central part of the Rhône Delta (France), is a complex shallow coastal lagoon, exposed to a typical Mediterranean climate and a specific hydrological regime affected by man-controlled exchanges with the sea and agricultural drainage channels. In this article, we report the results obtained by a series of monitoring programs, with different spatial and temporal resolutions. Long-term datasets from 1999 to 2019 with data collected on a monthly basis and a high spatial resolution highlighted the significant spatial heterogeneity in salinity regimes, and helped to determine the long-term evolution of the total mass of dissolved salt. High-frequency surveys allowed to characterize the water levels and salinity dynamics seasonal response to (i) the exchanges with the Mediterranean Sea, (ii) the exchanges with agricultural drainage channels, and (iii) the rain and evaporation. In addition, wind effects on salinity variations are also explored. This work shows how different spatial and temporal monitoring strategies provide complementary information on the dynamic of such a complex system. Results will be useful and provide insight for the management of similar lagoon systems, accommodating for both human activities and ecological stakes in the context of global change. Full article

Lagoon sediments have heterogeneous structure and texture, contain shells and plants and are often highly bioturbated and disturbed by human activities. In such sediments, the selection of representative cores and the choice of a subsampling strategy are important but difficult. In this study, we examine the usefulness of X-ray computed tomography (CT) for inferring sediment features that will help in making optimal decisions prior to core opening (24 cores from seven lagoons). Various algorithms (intensity projections, slice thickness, axial and sagittal images, CT number profiles and volumetric region of interest) are tested to visualise low- and high-density volumes or objects and to quantify the relations between the average volumetric CT number and the bulk density of the sediment matrix. The CT number is related mainly to water content and indirectly to total nitrogen and <16-μm grain-size fraction (model R2 = 0.94). The outliers are attributed to a weak correspondence between the fraction of sediment sampled for water content determination and the volume of sediment matrix used for CT number measurements in highly heterogeneous sediment slices. In conclusion, CT is a powerful tool for the initial screening of cores recovered from heterogeneous lagoon sediments. The adequate use of available algorithms may provide quantitative information on various sediment features, allowing the purposeful selection of cores and subsamples for further investigation.

The use of molecular tools (DNA barcoding and metabarcoding) for the identification of species and ecosystem biomonitoring is a promising innovative approach. The effectiveness of these tools is, however, highly dependent on the reliability and coverage of the DNA sequence reference libraries and it also depends on the identification of primer sets that work on the broadest range of taxa. In this study, a gap analysis of available DNA barcodes in the international libraries was conducted using the aquatic macroinvertebrate species checklist of the Apulia region in the southeast of Italy. Our analyses show that 42% of the 1546 examined species do not have representative DNA barcodes in the reference libraries, indicating the importance of working toward their completeness and addressing this effort toward specific taxonomic groups. We also analyzed the DNA barcode reference libraries for the primer set used to barcode species. Only for 52% of the examined barcoded species were the primers reported, indicating the importance of uploading this information in the databases for a more effective DNA barcode implementation effort and extensive use of the metabarcoding method. In this paper, a new combination of primers has revealed its experimental effectiveness at least on the species belonging to the three most represented taxa in the aquatic ecosystems of the Apulia region, highlighting the opportunity to develop combinations of primers useful at the regional level and the importance of studying DNA barcode gaps at the local/regional level. The DNA barcode coverage also varies among different taxonomic groups and aquatic ecosystem types in which a large number of species are rare. We tested the application of the DNA barcoding single species to a lagoon ecosystem (the lagoon named “Acquatina di Frigole” in the Apulia region) and we sampled two macroinvertebrate species lacking DNA barcodes from “Aquatina di Frigole” NATURA 2000 Site IT9150003, Fabulina fabula and Tritia nitida, generated two new CO1 barcodes and added them to a DNA barcode reference library.
