Abstract: Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, and providing food for predators. Their differences in tolerances and short generation times manifest in rapid community responses to change. Macroinvertebrate community composition is an indicator of water quality. In Europe, efforts to improve water quality following environmental legislation, primarily starting in the 1980s, may have driven a recovery of macroinvertebrate communities. Towards understanding temporal and spatial variation of these organisms, we compiled the TREAM dataset (Time seRies of European freshwAter Macroinvertebrates), consisting of macroinvertebrate community time series from 1,816 river and stream sites (mean length of 19.2 years and 14.9 sampling years) of 22 European countries sampled between 1968 and 2020. In total, the data include >93 million sampled individuals of 2,648 taxa from 959 genera and 212 families. These data can be used to test questions ranging from identifying drivers of the population dynamics of specific taxa to assessing the success of legislative and management restoration efforts.

Abstract: Humans impact terrestrial, marine and freshwater ecosystems, yet many broad-scale studies have found no systematic, negative biodiversity changes (for example, decreasing abundance or taxon richness). Here we show that mixed biodiversity responses may arise because community metrics show variable responses to anthropogenic impacts across broad spatial scales. We first quantified temporal trends in anthropogenic impacts for 1,365 riverine invertebrate communities from 23 European countries, based on similarity to least-impacted reference communities. Reference comparisons provide necessary, but often missing, baselines for evaluating whether communities are negatively impacted or have improved (less or more similar, respectively). We then determined whether changing impacts were consistently reflected in metrics of community abundance, taxon richness, evenness and composition. Invertebrate communities improved, that is, became more similar to reference conditions, from 1992 until the 2010s, after which improvements plateaued. Improvements were generally reflected by higher taxon richness, providing evidence that certain community metrics can broadly indicate anthropogenic impacts. However, richness responses were highly variable among sites, and we found no consistent responses in community abundance, evenness or composition. These findings suggest that, without sufficient data and careful metric selection, many common community metrics cannot reliably reflect anthropogenic impacts, helping explain the prevalence of mixed biodiversity trends.

Abstract: Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, and providing food for predators. Their differences in tolerances and short generation times manifest in rapid community responses to change. Macroinvertebrate community composition is an indicator of water quality. In Europe, efforts to improve water quality following environmental legislation, primarily starting in the 1980s, may have driven a recovery of macroinvertebrate communities. Towards understanding temporal and spatial variation of these organisms, we compiled the TREAM dataset (Time seRies of European freshwAter Macroinvertebrates), consisting of macroinvertebrate community time series from 1,816 river and stream sites (mean length of 19.2 years and 14.9 sampling years) of 22 European countries sampled between 1968 and 2020. In total, the data include >93 million sampled individuals of 2,648 taxa from 959 genera and 212 families. These data can be used to test questions ranging from identifying drivers of the population dynamics of specific taxa to assessing the success of legislative and management restoration efforts.

Abstract: Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European countries between 1968 and 2020, we quantified temporal trends in taxonomic and functional diversity and their responses to environmental pressures and gradients. We observed overall increases in taxon richness (0.73% per year), functional richness (2.4% per year) and abundance (1.17% per year). However, these increases primarily occurred before the 2010s, and have since plateaued. Freshwater communities downstream of dams, urban areas and cropland were less likely to experience recovery. Communities at sites with faster rates of warming had fewer gains in taxon richness, functional richness and abundance. Although biodiversity gains in the 1990s and 2000s probably reflect the effectiveness of water-quality improvements and restoration projects, the decelerating trajectory in the 2010s suggests that the current measures offer diminishing returns. Given new and persistent pressures on freshwater ecosystems, including emerging pollutants, climate change and the spread of invasive species, we call for additional mitigation to revive the recovery of freshwater biodiversity.

Abstract: Recent advances in molecular biomonitoring open new horizons for aquatic ecosystem assessment. Rapid and cost-effective methods based on organismal DNA or environmental DNA (eDNA) now offer the opportunity to produce inventories of indicator taxa that can subsequently be used to assess biodiversity and ecological quality. However, the integration of these new DNA-based methods into current monitoring practices is not straightforward, and will require coordinated actions in the coming years at national and international levels. To plan and stimulate such an integration, the European network DNAqua-Net (COST Action CA15219) brought together international experts from academia, as well as key environmental biomonitoring stakeholders from different European countries. Together, this transdisciplinary consortium developed a roadmap for implementing DNA-based methods with a focus on inland waters assessed by the EU Water Framework Directive (2000/60/EC). This was done through a series of online workshops held in April 2020, which included fifty participants, followed by extensive synthesis work. The roadmap is organised around six objectives: 1) to highlight the effectiveness and benefits of DNA-based methods, 2) develop an adaptive approach for the implementation of new methods, 3) provide guidelines and standards for best practice, 4) engage stakeholders and ensure effective knowledge transfer, 5) support the environmental biomonitoring sector to achieve the required changes, 6) steer the process and harmonise efforts at the European level. This paper provides an overview of the forum discussions and the common European views that have emerged from them, while reflecting the diversity of situations in different countries. It highlights important actions required for a successful implementation of DNA-based biomonitoring of aquatic ecosystems by 2030.

Abstract: Rivers are dynamic ecosystems in which both human impacts and climate-driven drying events are increasingly common. These anthropogenic and natural stressors interact to influence the biodiversity and functioning of river ecosystems. Disentangling ecological responses to these interacting stressors is necessary to guide management actions that support ecosystems adapting to global change. We analysed the independent and interactive effects of human impacts and natural drying on aquatic invertebrate communities—a key biotic group used to assess the health of European freshwaters. We calculated biological response metrics representing communities from 406 rivers in eight European countries: taxonomic richness, functional richness and redundancy, and biomonitoring indices that indicate ecological status. We analysed metrics based on the whole community and a group of taxa with traits promoting resistance and/or resilience (‘high RR’) to drying. We also examined how responses vary across Europe in relation to climatic aridity. Most community metrics decreased independently in response to impacts and drying. A richness-independent biomonitoring index (the average score per taxon; ASPT) showed particular potential for use in biomonitoring, and should be considered alongside new metrics representing high RR diversity, to promote accurate assessment of ecological status. High RR taxonomic richness responded only to impacts, not drying. However, these predictors explained little variance in richness and other high RR metrics, potentially due to low taxonomic richness. Metric responsiveness could thus be enhanced by developing region-specific high RR groups comprising sufficient taxa with sufficiently variable impact sensitivities to indicate ecological status.

Abstract: Intermittent rivers and Ephemeral Streams (IRES) are river water bodies characterised by temporary flow. They are widespread across the EU and a significant proportion of them is expected to increase due to climate change scenarios and rising water demands. The purpose of this handbook is to help water managers to understand the natural processes prevailing in IRES and their importance for biodiversity and local communities in order to better manage them. Since it is widely accepted that these types of systems have been up until recently neglected, the transfer of knowledge from scientists to water managers is required for their proper ecological status assessment, and crucial for their protection and restoration. Therefore, this SMIRES handbook will also bring about a better understanding of IRES, and will provide for the provision of tools needed for managing them in the best possible way. Eight case studies, located in different countries, aim at illustrating different experiments of managing IRES where the knowledge previously presented in the handbook is needed and used. These experiments do not claim to be exemplary practices to be reproduced everywhere but instead give insights of what could be done, what should be strengthened and what should be avoided in specific contexts. The issues are various: restoration of habitats, reduction of erosion, flood prevention, mitigation of hydrological drought, raise of groundwater levels, etc. Among the lessons learned, all case studies insist on the importance of increasing people awareness about the ecosystem services associated with IRES and encourage local stakeholders to involve themselves in restoration projects of IRES. A specific attention to project monitoring is also pointed out to assess the outputs and to encourage other initiatives to be taken.

Abstract: Invasive alien species (IAS) are known to be a major threat to biodiversity and ecosystem function and there is increasing evidence of their impacts on human health and economies globally. We undertook horizon scanning using expert-elicitation to predict arrivals of IAS that could have adverse human health or economic impacts on the island of Cyprus. Three hundred and twenty five IAS comprising 89 plants, 37 freshwater animals, 61 terrestrial invertebrates, 93 terrestrial vertebrates, and 45 marine species, were assessed during a two-day workshop involving 39 participants to derive two ranked lists: (1) IAS with potential human health impacts (20 species ranked within two bands: 1–10 species or 11–20 species); and, (2) IAS with potential economic impacts (50 species ranked in three bands of 1–10, 11–20, and 21–50). Five species of mosquitoes (Aedes aegypti, Aedes albopictus, Aedes flavopictus, Aedes japonicus, and Culex quinquefasciatus) were considered a potential threat to both human health and economies. It was evident that the IAS identified through this process could potentially arrive through many pathways (25 and 23 pathways were noted for the top 20 IAS on the human health and economic impact lists respectively). The Convention on Biological Diversity Level II (subcategory) pathways Contaminant on plants, pet/aquarium/terrarium species (including live food for such species), hitchhikers in or on aeroplanes, hitchhikers in or on ship/boats, and vehicles were the main pathways that arose across both lists. We discuss the potential of horizon scanning lists to inform biosecurity policies and communication around IAS, highlighting the importance of increasing understanding amongst all stakeholders, including the public, to reduce the risks associated with predicted IAS arrivals.

Abstract: Intermittent rivers and ephemeral streams (IRES) are common across Europe and dominate some Mediterranean river networks. In all climate zones, IRES support high biodiversity and provide ecosystem services. As dynamic ecosystems that transition between flowing, pool, and dry states, IRES are typically poorly represented in biomonitoring programmes implemented to characterize EU Water Framework Directive ecological status. We report the results of a survey completed by representatives from 20 European countries to identify current challenges to IRES status assessment, examples of best practice, and priorities for future research. We identify five major barriers to effective ecological status classification in IRES: 1. the exclusion of IRES from Water Framework Directive biomonitoring based on their small catchment size; 2. the lack of river typologies that distinguish between contrasting IRES; 3. difficulties in defining the 'reference conditions' that represent unimpacted dynamic ecosystems; 4. classification of IRES ecological status based on lotic communities sampled using methods developed for perennial rivers; and 5. a reliance on taxonomic characterization of local communities. Despite these challenges, we recognize examples of innovative practice that can inform modification of current biomonitoring activity to promote effective IRES status classification. Priorities for future research include reconceptualization of the reference condition approach to accommodate spatiotemporal fluctuations in community composition, and modification of indices of ecosystem health to recognize both taxon-specific sensitivities to intermittence and dispersal abilities, within a landscape context.

Abstract: The presence of the large branchiopod Triops cancriformis (Bosc, 1801-1802) in Cyprus is reported for the first time. Triops cancriformis individuals were observed in the large temporary wetland of Paralimni Lake (Famagusta District, Cyprus) during the wet periods of 2013 and 2014. This finding extends the current knowledge of the species distribution in the eastern Mediterranean area and stresses the ecological and conservation value of the unique habitat of Paralimni Lake. In addition, it highlights the need to conduct further studies on the fauna of temporary pond habitats in Cyprus and the need to implement better conservation management strategies for this EU priority habitat., Se reporta por primera vez, la presencia del braquiópodo Triops cancriformis (Bosc, 1801-1802) en Chipre. Se detectaron individuos de T.cancriformis en el gran humedal temporal del lago Paralimni (Distrito de Famagusta, Chipre) durante los períodos de lluvia de 2013 y 2014. Este hallazgo amplía el conocimiento actual de la distribución de esta especie en el área del Mediterráneo oriental, y hace hincapié en el valor ecológico y la conservación del hábitat singular del lago Paralimni. Además, pone de relieve la necesidad de seguir estudiando la fauna de lagunas temporales en Chipre con el objetivo de mejorar su gestión para la conservación de dichos hábitats catalogados como prioritarios de la UE.

Abstract: Τα παράκτια μεταβατικά οικοσυστήματα όπως οι λιμνοθάλασσες και οι αλυκές, αποτελούν δυναμικά οικοσυστήματα και παρουσιάζουν έντονες χωρικές και χρονικές διακυμάνσεις, αφού ως οικότονοι μεταξύ ξηράς και θάλασσας, δέχονται την ταυτόχρονη επίδραση χερσαίου και θαλάσσιου περιβάλλοντος. Παράλληλα είναι οικοσυστήματα υψηλής παραγωγικότητας, αφού φιλοξενούν είδη με υψηλή πρωτογενή παραγωγικότητα. Τα υδρόβια μακρόφυτα αποτελούν δομικά και λειτουργικά στοιχεία των οικοσυστημάτων αυτών και σύμφωνα με την Οδηγία Πλαίσιο 2000/60/ΕΕ, αποτελούν ποιοτικά στοιχεία και χρησιμοποιούνται ως βιοδείκτες για την εκτίμηση της οικολογικής ποιότητας των υδάτινων οικοσυστημάτων. Στα πλαίσια της παρούσας μεταπτυχιακής διατριβής, διερευνήθηκαν οι σχέσεις μεταξύ αβιοτικών και βιοτικών παραμέτρων της υδάτινης στήλης, στις λιμνοθάλασσες Κοτύχι και Πρόκοπο της ΒΔ Πελοποννήσου και στις αλυκές Λάρνακας και στον υγρότοπο Ακρωτηρίου (Αλυκές Ακρωτηρίου, λιβάδι Φασουρίου) της Κύπρου. Πραγματοποιήθηκαν μηνιαίες δειγματοληψίες κατά την βλαστητική περίοδο των ετών 2006, 2007 και 2008, στην διάρκεια των οποίων καταγράφηκαν οι φυσικοχημικές παράμετροι των υδάτων, όπως βάθος (m), διαφάνεια (m), θερμοκρασία (οC), αλατότητα (‰), αγωγιμότητα (mS/cm), διαλυμένο οξυγόνο (mg/l), pH, ολικά αιωρούμενα στερεά (mg/l), φωτοσυνθετικά ενεργή ακτινοβολία- PAR ενώ υπολογίστηκαν οι συγκεντρώσεις της Chl-α (mg/m3) η αλκαλικότητα (mg/l), η συγκέντρωση των θρεπτικών αλάτων φωσφόρου-SRP (mg/l) και αζώτου - NO2-N, NO3-N και ΝΗ4-Ν (mg/l), καθώς και η σταθερά απορρόφησης Κ (m-1) της υδάτινης στήλης. Παράλληλα συλλέχθηκαν ποσοτικά και ποιοτικά δεδομένα που αφορούν τη δομή των μακροφυτικών κοινωνιών, καθώς και την χωρική και χρονική διακύμανση της κατανομής και της ανάπτυξης των μακροφυτικών ειδών που απαντώνται στις λιμνοθάλασσες και στις αλυκές. Τέλος διερευνήθηκαν οι σχέσεις μεταξύ αβιοτικών παραμέτρων και ειδών μακροφύτων και εξετάστηκαν οι πιθανοί παράγοντες που επηρεάζουν την ανάπτυξη και την κατανομή των μακροφύτων. Για την διερεύνηση της δομής των μακροφυτικών κοινωνιών, την ταξινόμηση της υδρόβιας βλάστησης σε ευδιάκριτες ομάδες, καθώς και την ομαδοποίηση των σταθμών δειγματοληψίας ανάλογα με την σύνθεση της βλάστησης τους, εφαρμόστηκαν οι μέθοδοι ταξινόμησης TWINSPAN και MDS. Χρησιμοποιήθηκαν επίσης οι συντελεστές συσχέτισης Pearson (r) και Kendall (tau-b), προκειμένου να εξεταστεί η ύπαρξη πιθανών συσχετίσεων μεταξύ των φυσικοχημικών παραμέτρων, αλλά και μεταξύ βιοτικών και αβιοτικών παραμέτρων, ενώ πραγματοποιήθηκε ανάλυση διασποράς (one-way ANOVA) προκειμένου να διαπιστωθούν στατιστικά σημαντικές διαφορές μεταξύ των περιοχών μελέτης, αλλά και μεταξύ των διαφορετικών ομάδων βλάστησης. Τέλος, για την διερεύνηση των αβιοτικών παραμέτρων που επηρεάζουν την ανάπτυξη και την κατανομή των μακροφύτων, εφαρμόστηκε η μέθοδος ανάλυσης κανονικών αντιστοιχιών CCA (Canonical Correspondence Analysis). Στις τέσσερις περιοχές μελέτης καταγράφηκαν συνολικά 29 taxa μακροφύτων, τα οποία ταξινομήθηκαν σε έξι ομάδες βλάστησης. Πέντε taxa από αυτά, αναφέρονται για πρώτη φορά στην Κύπρο. Τα είδη με την μεγαλύτερη αφθονία στις περιοχές μελέτης ήταν τα Ruppia cirrhosa, Potamogeton pectinatus, Najas marina ssp. armata, Althenia filiformis, Lamprothamnium papulosum και Ulva lactuca. Η βιομάζα των κυρίαρχων ειδών παρουσίασε εποχικές διακυμάνσεις με τις μέγιστες τιμές να καταγράφονται την άνοιξη και το καλοκαίρι. Στις λιμνοθάλασσες Κοτύχι και Πρόκοπο παρατηρήθηκε οικολογική διαδοχή ειδών στη διάρκεια της βλαστητικής περιόδου, η οποία μπορεί να αποδοθεί σε σημαντικές αλλαγές του αβιοτικού περιβάλλοντος (π.χ. αλατότητας), όπως η αντικατάσταση του είδους Potamogeton pectinatus από το αγγειόσπερμο Ruppia cirrhosa, ενώ η εμφάνιση ευτροφικών φαινομένων με σημαντική αύξηση της βιομάζας ευκαιριακών ειδών (π.χ. χλωρόφυτα), οδήγησε στην μείωση της βιομάζας των αγγειοσπέρμων. Στις αλυκές Λάρνακας και Ακρωτηρίου η βιομάζα κυμάνθηκε σε πολύ χαμηλά επίπεδα πιθανώς λόγω των πολύ ψηλών τιμών αλατότητας. Τις υψηλότερες τιμές βιομάζας παρουσίασε το αγγειόσπερμο Althenia filiformis τον Απρίλιο. Την βλαστητική περίοδο 2008 οι μεγαλύτερες τιμές αλατότητας που καταγράφηκαν στις αλυκές Λάρνακας και Ακρωτηρίου, δεν ευνόησαν την ανάπτυξη μακροφύτων. Αντίθετα στο λιβάδι Φασουρίου όπου η αλατότητα ήταν σημαντικά χαμηλότερη, η βιομάζα του κυρίαρχου Najas marina ssp. armata κυμάνθηκε σε υψηλές τιμές με τις μεγαλύτερες να καταγράφονται τον Ιούνιο. Από την διερεύνηση των μορφομετρικών χαρακτηριστικών του αγγειόσπερμου Ruppia cirrhosa, προέκυψε ότι η πυκνότητα των πληθυσμών του είδους κυμάνθηκε στα ίδια επίπεδα με άλλες λιμνοθάλασσες της Μεσογείου (449–5120 βλαστοί/m2), ενώ παρουσίασε θετική συσχέτιση με την θερμοκρασία και αρνητική συσχέτιση με την συγκέντρωση ολικού φωσφόρου. Το μήκος των φύλλων συσχετίστηκε θετικά με την συγκέντρωση των όξινων ανθρακικών ιόντων, τα οποία σε χαμηλές συγκεντρώσεις μπορεί να αποτελέσουν περιοριστικό παράγοντα για την ανάπτυξη των μακροφύτων. Η μεγαλύτερη ποικιλότητα μακροφύτων (δείκτης Shannon-Weaner) καταγράφηκε στην λιμνοθάλασσα Πρόκοπο, ενώ οι αλυκές Λάρνακας παρουσίασαν την χαμηλότερη ποικιλότητα, πιθανά λόγω του ότι οι υψηλές τιμές αλατότητας δεν ευνοούν την ανάπτυξη πολλών ειδών μακροφύτων. Η εφαρμογή του δείκτη οικολογικής αξιολόγησης ΕΕΙ (Ecological Evaluation Index) για την εκτίμηση της οικολογικής ποιότητας των υδάτων με την χρήση των μακροφύτων ως βιοδεικτών, είχε ως αποτέλεσμα την ταξινόμηση της ποιότητας των υδάτων της λιμνοθάλασσας Κοτυχίου ως Μέτρια, της λιμνοθάλασσας Πρόκοπος και των αλυκών Λάρνακας ως Καλή, ενώ του υγρότοπου Ακρωτηρίου μπορούν να χαρακτηριστούν ως Υψηλής οικολογικής ποιότητας. Oι σημαντικότερες περιβαλλοντικές παράμετροι που καθορίζουν την σύνθεση των ομάδων βλάστησης, αλλά και την εξάπλωση των ειδών των μακροφύτων στις περιοχές έρευνας, είναι το υδατικό ισοζύγιο, η αλατότητα και οι συγκεντρώσεις των θρεπτικών αλάτων. Στα πλαίσια προστασίας και διατήρησης των παράκτιων αυτών υγροτόπων, προτείνεται ο σχεδιασμός ενός μόνιμου δικτύου παρακολούθησης βιοτικών και αβιοτικών παραμέτρων και η διεξαγωγή συστηματικής έρευνας με την πραγματοποίηση οικολογικών μελετών χρησιμοποιώντας βιοτικά στοιχεία για την εκτίμηση της οικολογικής τους ποιότητας. Επίσης, η λήψη διαχειριστικών μέτρων για τον περιορισμό της εισροής θρεπτικών στους υγρότοπους, κρίνεται επιτακτική αφού η εμφάνιση ευτροφικών φαινομένων αποτελεί διαρκεί απειλή για τα υδάτινα οικοσυστήματα. Η απαγόρευση καταπάτησης των οικοτόπων, της απόρριψης σκουπιδιών, της βόσκησης και της θήρευσης, μπορεί να υλοποιηθεί με την λήψη και εφαρμογή αυστηρών μέτρων, καθώς και με την φύλαξη των περιοχών αυτών. Η περίφραξη και η σηματοδότηση επιλεγμένων σημείων, ο καθαρισμός απορριμμάτων, η απομάκρυνση ξενικών ειδών και ο καθαρισμός των καναλιών που συλλέγουν και διοχετεύουν νερό από την λεκάνη απορροής στους υγρότοπους, μπορούν να βοηθήσουν στην διατήρηση των υγροτόπων και την βελτίωση της οικολογικής τους κατάστασης. Επίσης, η πραγματοποίηση ειδικών περιβαλλοντικών μελετών πρέπει πάντα να προηγείται της υλοποίησης κάθε μορφής έργων. Τέλος η ενημέρωση και ευαισθητοποίηση του κοινού με την απρόσκοπτη λειτουργία κέντρων περιβαλλοντικής ενημέρωσης και φορέων διαχείρισης των περιοχών αυτών, κρίνεται απαραίτητη προκειμένου οι υγρότοποι να προστατευτούν και να αποφευχθεί η σταδιακή υποβάθμιση τους. Lagoons and other coastal wetlands are shallow aquatic environments located in the transitional zone between terrestrial and marine ecosystems, which can span from freshwater to hypersaline conditions depending on their water balance. They exhibit an extreme spatial and temporal variability of environmental parameters and are recognized as highly productive ecosystems. Aquatic macrophytes are key structural and functional components of aquatic ecosystems. As photosynthetic sessile organisms being at the base of food web, are vulnerable and adaptive to human and environmental stress. They respond to aquatic environment representing reliable indicators of its changes and are mentioned in the WFD as biological quality elements for the ecological classification of transitional and coastal waters. In the present work, the relationships between biotic and abiotic parameters of the water column were investigated in coastal lagoons of Kotychi and Prokopos (NW Peloponnisos, Greece), Larnaca salt lakes and Akrotiri wetland (Cyprus). Monthly samplings were conducted during the vegetative periods of the years 2006, 2007 and 2008 and water parameters such as depth (m), transparency (m), temperature (οC), salinity (‰), conductivity (mS/cm), dissolved oxygen (mg/l), pH, photosynthetic active radiation – PAR and attenuation coefficient K (m-1) were recorded in situ, while Chl-α (mg/m3), total suspended matter (mg/l), alkalinity and nutrients of nitrogen and phosphorus (mg/l) were determined in the laboratory. Quantitative and qualitative data concerning aquatic macrophyte flora were recorded during the same period, such as species composition, community structure, spatial and temporal variations of species abundance and the succession of submerged macrophytes in relation to the main environmental factors. The aquatic macrophytic community was distinguished in different vegetation groups using TWINSPAN and MDS techniques. Correlations between environmental parameters were tested using Pearson and Kendall correlation tests, while One –way ANOVA was used to determine statistical significant differences of environmental variables between different study areas and distinguished plant groups. Finally CCA was performed in order to examine relationships between the species abundance and environmental variables. In total, 29 taxa were recorded in all four study areas and were classified in six vegetation groups. Five species were recorded for the first time in the island of Cyprus. The most abundant species were Ruppia cirrhosa, Potamogeton pectinatus, Najas marina ssp. armata, Althenia filiformis, Lamprothamnium papulosum και Ulva lactuca. The biomass of dominant species showed seasonal variations and maximum biomass values were recorded in late spring and summer. In Kotychi and Prokopos lagoons, the replacement of Potamogeton pectinatus by Ruppia cirrhosa was recorded, probably due to significant increase of salinity. In other parts of the lagoons, the replacement of macrophyte beds due to increased macroalgal proliferation was also recorded. In Larnaca and Akrotiri salt lakes, biomass values were significantly lower as a result of high salinity values. The most abundant species was Althenia filiformis (biomass peak in April). During the vegetative period of 2008, extreme salinity values were recorded as a result of reduced rainfall. High salinity values resulted in scarse occurrence of macrophytes in the salt lakes during this period. In Fasouri marsh, which is characterized by minimum salinity values, the dominant species Najas marina ssp. armata showed high biomass values (peak in June). Regarding the results of Ruppia cirrhosa population’s density in Kotychi lagoon (449-5120 shoots/m2), they were comparable with data from other Mediterranean lagoons. Meadows density was positively correlated with temperature and negatively correlated with total phosphorus. Leaf length showed positive correlation with bicarbonate ions, which can be a restrictive factor for the growth of macrophytes. The highest macrophyte diversity (Shannon-Weaner index) was found in Prokopos lagoon, whereas Larnaca salt lakes had the lowest values, probably due to high salinity. The implementation of EEI (Ecological Evaluation Index) for the assessment of the ecological quality of coastal and transitional waters, showed that Kotychi lagoon was classified into Moderate ecological class. Prokopos lagoon and Larnaca salt lakes were classified into Good ecological class and finally Akrotiri wetland was classified into High ecological class. Hydrological regime, salinity and nutrient concentrations seem to be the key factors controlling macrophyte composition, community structure and species abundance. For the conservation and management of these coastal and transitional wetlands, we propose the development of a monitoring network for biotic and abiotic parameters. Ecological studies for the evaluation of ecological quality of the wetlands according to the WFD 200/60/EU and implementation of management practices for the reduction of nutrient inflows in the wetlands are needed, in order to reduce eutrophication phenomena, which are a severe threat for the ecological balance of the wetlands. The encroachment of wetlands, hunting and waste discharges, should be prohibited by law. Finally, the increase of public environmental awareness will have significant results in the conservation of coastal wetlands.
