Prompt estimation of phytoplankton biomass is critical in determining the ecological quality of freshwaters. Remote Sensing (RS) may provide new opportunities to integrate with situ traditional monitoring techniques. Nonetheless, wide regional and temporal variability in freshwater optical constituents makes it difficult to design universally applicable RS protocols. Here, we assessed the potential of two neural networks-based models, namely the Case 2 Regional CoastColour (C2RCC) processor and the Mixture Density Network (MDN), applied to MSI Sentinel-2 data for monitoring Chlorophyll (Chl) content in three monomictic volcanic lakes while accounting for the effect of their specific water circulation pattern on the remotely-sensed and in situ data relation. Linear mixed models were used to test the relationship between the remote sensing indices calculated through C2RCC (INN) and MDN (IMDN), and in situ Chl concentration. Both indices proved to explain a large portion of the variability in the field data and exhibited a positive and significant relationship between Chl concentration and satellite data, but only during the mixing phase. The significant effect of the water circulation period can be explained by the low responsiveness of the RS approaches applied here to the low phytoplankton biomass, typical of the stratification phase. Sentinel-2 data proved their valuable potential for the remote sensing of phytoplankton in small inland water bodies, otherwise challenging with previous sensors. However, caution should be taken, since the applicability of such an approach on certain water bodies may depend on hydrological and ecological parameters (e.g., thermal stratification and seasonal nutrient availability) potentially altering RS chlorophyll detection by neural networks-based models, despite their alleged global validity.

Inland freshwaters are of great importance for human health and activities, but major stressors such as nutrient pollution, deforestation, and urbanization are compromising their status. Water quality degradation and freshwater ecosystem preservation are current issues worldwide requiring frequent and efficient monitoring protocols. The increasing need for large amounts of data to comply with national and international regulations on water quality monitoring highlights traditional procedures limits. Therefore, the purpose of the present study is to investigate the potential of alternative and rapid methods for chlorophyll concentration surveys in freshwaters. The Phyto-PAM (pulse amplitude-modulated) instrument and the Case-2 Regional Coast Colour (C2RCC) satellite image processor were selected to estimate chlorophyll concentration in the surface waters of Lake Albano (Central Italy), selected as a pilot area for the project BLOOWATER (Water JPI 2018 Joint Call Closing the Water Cycle Gap). The correlation tests’ results indicate significant relations with chlorophyll data measured spectrophotometrically, confirming the suitability of both methods for chlorophyll retrieval. However, the relatively low strength of the correlation between remotely sensed and spectrophotometric data (r = 0.57, p < 2.2 × 10−16) was not as satisfactory as with Phyto-PAM values (r = 0.97, p = 1.2 × 10−4). Even though the techniques in this study proved to be promising in the water body under investigation, their current limitations suggest the need for further calibration and integration with other systems (e.g., unmanned aerial vehicles).

The release of plastics in freshwater is an increasing concern for ecosystem safety worldwide. There is a large knowledge gap on plastic pollution in Mediterranean freshwater, especially regarding surveys along entire river courses, partly due to the absence of guidelines for standardized monitoring of plastics. The present study analyzes the plastic distribution from source to mouth, also according to the River Continuum Concept, of the environmental matrices (water and sediments) and biota (caddisfly cases) of the Mediterranean River Mignone and their cause-effect relationship. The results of the water quality indices (Extended Biotic Index and Fluvial Functionality Index) were compared with the plastic concentrations observed in the water and sediments to explore what relationship there might be and to understand if the indices could be a proxy of the plastic pollution. Our results showed a significant prevalence of blue fibers, the concentration of which in water and sediment is positively associated. Plastic concentration at each site was not accurately detected by the water quality indices. These results may suggest that the factors considered by water quality indices are not able to detect the contamination of plastic pollution. It is mandatory to identify new tools for assessing the plastic impacts on river ecosystems.

Plastic has become a “hot topic” for aquatic ecosystems’ conservation together with other issues such as climate change and biodiversity loss. Indeed, plastics may detrimentally affect habitats and biota. Small plastics, called microplastics, are more easily taken up by freshwater organisms, causing negative effects on growth, reproduction, predatory performance, etc. Since available information on microplastics in freshwater are fragmentary, the aim of this review is twofold: (i) to show, analyse, and discuss data on the microplastics concentration in freshwater and (ii) to provide the main polymers contaminating freshwater for management planning. A bibliographic search collected 158 studies since 2012, providing the scientific community with one of the largest data sets on microplastics in freshwater. Contamination is reported in all continents except Antarctica, but a lack of information is still present. Lentic waters are generally more contaminated than lotic waters, and waters are less contaminated than sediments, suggested to be sinks. The main contaminating polymers are polypropylene and polyethylene for sediment and water, while polyethylene and polyethylene terephthalate are mainly found in biota. Future research is encouraged (1) to achieve a standardised protocol for monitoring, (2) to identify sources and transport routes (including primary or secondary origin), and (3) to investigate trophic transfer, especially from benthic invertebrates.

Several biological levels are considered as signals of environmental perturbations so that integrative biological responses have been proposed in environmental monitoring activities. We evaluated the use of markers in Mytilus galloprovincialis at two different levels (protein nitration and S-nitrosylation, and geometric morphometrics) to investigate the sea coastal environmental status. We studied adductor muscle, digestive gland and valves of mussels collected from 3 sampling sites (2 disturbed + 1 control) in eastern Tyrrhenian Sea, and 2 (1 + 1) in western Ionian Sea. Molecular and morphometric markers showed significant variations in relation to environmental conditions, but the most interesting result was evidenced by the analysis of covariation between both protein post-translational modifications and geometric morphometric descriptors. The main interesting finding regards the relationship between protein nitration values (an irreversible molecular marker) of both adductor muscle and digestive gland, and geometric morphometric descriptors (that are Procrustes’ distances) of valve shapes. Molecular and morphometric markers revealed useful warning systems in detecting environmental changes, even if causes and mechanisms altering both cellular metabolism and shape morphology are still unclear. Our findings suggested that pollutants affected the normal cellular metabolic pathways altering the correct functionality at higher biological levels and producing developmental detrimental noise visible on the shell.

Cherax destructor is a crayfish endemic to south-eastern Australia and one of the last alien crayfish to be introduced in Italy. In the Laghi di Ninfa Natural Reserve (Latium region, Central Italy), the species was probably introduced in 1999, but only reported for the first time in 2008. Nearby this area, the most widespread alien crayfish is the red swamp crayfish Procambarus clarkii. In the Natural Reserve, between 2008 and 2013 and during spring and summer, crayfish sampling was carried out with baited traps to assess the distribution of C. destructor and its possible relationship with P. clarkii. Cherax destructor was first recorded in 2008; few P. clarkii were detected in the cultivation ponds where C. destructor was present in 2012 and 2013. Moreover, crayfish plague analyses evidenced a positive result in two out of the 12 sampled P. clarkii. Cherax destructor is now completely absent from the Natural Reserve, while P. clarkii has spread in the area and was probably responsible for this eradication since C. destructor is vulnerable to crayfish plague which was also detected in the area. An ecosystem restoration project in the area favoured the spread of. P. clarkii; the implications of this intervention are discussed.

Investigations on asymmetries showed that deviations from perfect bilateral symmetry are interpreted as environmental changes inducing developmental instability. Since morphological abnormalities increase with pollution, deformations may be considered indicators of the organism exposition to pollution. Therefore, the onset of asymmetry in otherwise normally symmetrical traits has been used as a measure of some stresses as well. In this context, we studied how marine pollution affects the valve morphological alterations in the mussel Mytilus galloprovincialis. We used 180 specimens (30 per site) from the aquaculture area of Goro (River Po delta, northern Adriatic Sea), translocated, and released within 50 × 50 × 50 cm cages in five sites: two disturbed and one undisturbed near Naples (eastern Tyrrhenian Sea), and one disturbed and one undisturbed near Siracusa (western Ionian Sea). Disturbed sites were stressed by heavy industrialization and heavy tankers traffic of crude and refined oil, and were defined basing on sediment contamination. In particular, by the cone-beam computed tomography we obtained 3D virtual valve surfaces to be analyzed by the geometric morphometric techniques. Specifically, we focused the levels of the shell shape fluctuating asymmetry in relation to the degrees of marine pollution in different sites of the Tyrrhenian Sea. The Mahalanobis distances (interpreted as proxy of the individual shape asymmetry deviation from the mean asymmetry) significantly regressed with the sediment contamination gradient. Indeed, although the left–right differences were normally distributed in each studied site, the individual asymmetry scores (IAS) significantly varied amongst the investigated sites. IAS showed higher values in disturbed areas than those of undisturbed ones in both Tyrrhenian and Ionian Sea. Our results are consistent with past studies on molluscans and other taxa, demonstrating some detrimental effects of chemicals on organisms, although the investigated morphological marker did not discriminate the real disturbance source. Our findings indicate that the mussels act as a prognostic tool for sea pollution levels driving detrimental effects on benthic community.

The regenerative ability of Hydra vulgaris was tested as potential biomarker for the development of a new eco-toxicological index. The test is based on the regeneration rate and the aberration frequency of the columna (body and adhesive foot) after separation from head and tentacles by a bistoury. Particularly, 45 columnae were submerged in the rearing solution (that is Hydra medium) to have control, and 285 in potential contaminated waters to have treatments, collected from 19 sites along 10 rivers in central Italy. ANCOVA and chi-square tests were used to compare values from each site to a laboratory control. Subsequently the values on regeneration rate and aberration frequency were inserted in a double entry matrix, where the match of the two entries in the matrix provides the score of the proposed Teratogenic Risk Index (TRI). Each score corresponded to one of the 5 teratogenic risk classes, to which a risk level was associated: from 1 (no risk) to 5 (very high risk). On the whole, 32% of the studied sites were classified as no teratogenic risk while the remaining showed a variable risk level from low to very high. This study proposed for the first time an early warning system to detect the presence of teratogens in running waters, providing a rapid and cost-effective evaluation method. Therefore, TRI may contribute to initiate adequate measures to manage riverine habitats, and to monitor the running water teratogenic status. Specifically, this index may provide the opportunity to identify the disturbance sources and then to drive the decisions, together with competent authorities, on the catchment and landscape management and on the possible use of waters for urban, agricultural, and industrial activities, since they may show significant effects on the human health.

The ecological integrity of lotic ecosystems is intimately linked to the quality of their catchments. Environmental protection efforts should therefore be implemented at the relevant catchment-scale in order to support river biodiversity and associated ecosystem services. Therefore, freshwater management can greatly benefit from tools that enable spatially-explicit predictions of water quality across heterogeneous landscapes. To this end, we investigated the relationships between the biological quality of running waters (expressed by the Italian Extended Biotic Index, EBI) and surrounding topographic and land cover matrices in central Italy. To do so, we adopted a spatial approach based on generalized linear models (GLM) that allowed us to identify the catchment features influencing the EBI values, and to produce a map of expected water quality in the region. A gap-analysis was then performed to assess the overlap between the existing regional protected areas and the modelled water quality map. Our findings provide suitable support for the identification of certain land uses in order to preserve riverine biodiversity and hopefully restore lotic ecosystems in Mediterranean catchments.

We studied the ontogenetic allometry pattern in the freshwater brachyuran crab Potamon fluviatile (Herbst, 1785) to describe some new sexual dimorphic features on the ontogenic trajectories of the chelae. We surveyed carapace width, chela length and width, dactylus length, and propodus length of both chelae of 93 females and 114 males to the nearest |${\rm{0}}{\rm{.05 \,mm}}$| using a vernier caliper. Our main result was the identification of morphological biometry showing a variability of the chela linked to growth allometry, with some different between-sex ontogenic trajectories. Specifically, we emphasized how the morphometric features of the chelae change during body-size growth with different increasing rates. Particularly, the observed significant shape changes are mainly due to positive allometries in both sexes, although negative allometries (the latter visible only in the propodus length of females) and isometries were observed as well. Our study confirms that a form of sexual dimorphism exists in the ontogenetic allometric trajectories of P. fluviatile in both the large and small chelae, these trajectories being related to mechanical aspects in predation, food manipulation, mate acquisition, and between-sex differences in aggressiveness during antagonistic fights.

Noninvasive methods in shell shape variation may help to understand evolution, ecology, stress and role of molluscan in aquatic ecosystems. Imaging analysis is a suitable diagnostic tool in morphological studies to (1) evaluate the health status of investigated animals, and (2) monitor sea coastal habitats. We introduce the feasibility of the cone-beam computed tomography as an optimal technique for 3D surface scanning to obtain virtual valve surfaces of Mytilus galloprovincialis, and analyze them exploiting the geometric morphometric facilities. Statistical output revealed morphological difference between mussels coming from different extensive rearing systems highlighting how the entire valve surface contributed to discriminate between groups when we compared 2- and 3D analyses. Many factors drive the morphological differences observed in the valve shape variation between the two sites, such as geographical genetic differentiation, natural environmental effects and culture conditions. The simplicity of the proposed methodology avoids damage and handling of individuals, makes this approach useful for morphological data collection, and helps to detect detrimental agents for sea ecosystems by using molluscans.

The brackish habitat colonization by the red swamp crayfish Procambarus clarkii (Girard, 1852) has aroused lively interest among many biologists. Here, we focused on its salinity tolerance by carrying out laboratory experiments and histomorphological observations on its antennal glands. Adult crayfish of similar size were subject to increasing salinity levels up to 35‰ in a recirculating system. Only one male molted, and no specimens died during the experiment (only 3 females and 1 male). The antennal gland tissue organization (mainly regarding labyrinth and nephridial tubules) in the treated crayfish showed alterations if compared with the control specimens. We never found sexual differences in both laboratory experiments and histological observations. Our data highlighted the P. clarkii ability to survive in high salinity levels. This tolerance ought to be investigated in order to improve our understanding of mechanisms driving the coastal brackish area colonization by P. clarkii.

This study aimed to contribute to understanding the role of changes in proportions related to variation in size in freshwater fish, particularly Rutilus rubilio, Squalius lucumonis and Telestes muticellus, from central Italy. The ontogenetic shape variation was described by a multivariate regression where the independent and dependent variables were size and a set of shape variables (the latter obtained from geometric morphometric analysis of 16 anatomical landmarks), respectively. Our analyses indicated: (1) proportional ontogenetic changes in several morphometric characters in all populations of the three species; (2) no geographical shape variation for each species; (3) interspecific differences. The main shape changes joining all the populations are the ocular area contraction, the tail peduncle enlargement, and the main changes involving the median body region. The shape variations showed similar modification patterns between R. rubilio and S. lucumonis (the silhouette passed from a streamlined to a more oval and higher shape for both species) and some differences between R. rubilio and S. lucumonis vs. T. muticellus (the latter approaching a more spindle-shaped body). The expression of these allometric trajectories may be associated with age-specific shifts in the ecological niche, optimizing some features such as foraging efficiency and movement.
