“…Cyanotoxins were a plausible cause for this bird's mass mortality episode in the Greek Karla Reservoir in 2016 (Papadimitriou et al 2018). Therefore, such cyanobacterial blooms pose threats for the rich, unique and vulnerable bird life of the lake.…”

The enactment of the Water Framework Directive (WFD) initiated scientific efforts to develop reliable methods for comparing prevailing lake conditions against reference (or nonimpaired) states, using the state of a set biological elements. Drawing a distinction between impaired and natural conditions can be a challenging exercise, as it stipulates the robust delineation of reference conditions along with the establishment of threshold values for key environmental variables used as proxies for the degree of system impairment. Another important aspect is to ensure that water quality assessment is comparable among the different Member States. In this context, the present paper offers a constructive critique of the practices followed during the WFD implementation in Greece by pinpointing methodological weaknesses and knowledge gaps that undermine our ability to classify the ecological status of Greek lakes. One of the pillars of WDF is a valid lake typology that sets ecological standards transcending geographic regions and national boundaries. The national typology of Greek lakes has failed to take into account essential components (e.g. surface area, altitude, salinity). WFD compliance assessments based on descriptions of phytoplankton communities areoversimplified and as such should be revisited. Exclusion of most chroococcal species from the analysis of cyanobacteria biovolume in Greek lakes and most reservoirs in the Mediterranean Geographical Intercalibration Group (Greece, Spain, Portugal and Cyprus) is not consistent with the distribution of those taxa in lakes. Similarly, the total biovolume reference values and the indices used in their classification schemes reflect misunderstandings of WFD core principles. This hampers the comparability of ecological status across Europe and leads to quality standards that are too relaxed to provide an efficient target especially for the protection and management of Greek/transboundary lakes such as Lake Megali Prespa, one of the oldest lakes in Europe.

“…Scholte 2006, Nager et al 2010, but also water quality (e.g. Papadimitriou et al 2017), could have also shaped the observed changes in the number and distribution of the Dalmatian Pelicans overwintering in our study area (Ashoori et al 2019). Moreover, winter site fidelity could also influence the movement pattern of the species, thus ultimately affecting its wintering distribution (Robertson & Cooke 1999).…”

“…Waterbirds, being ecologically dependent on wetlands and aquatic ecosystems, are considered important bio-indicators of environmental quality (Amat & Green 2010, Papadimitriou et al 2017, Amano et al 2018, Rahman & Ismail 2018 and provide a variety of ecosystem services to their environment (Green & Elmberg 2014). However, at the same time they are heavily impacted by natural and human-induced habitat deterioration and degradation (e.g.…”

“…Information on cyanotoxins in pelicans is very scarce; Burns [70] mentioned anatoxin-a in the gut and the liver of a Great White Pelican during surveys in 2000 (0.51 to 43.3 µg g −1 ). Papadimitriou et al [71] measured average MC concentrations of 231.1 ng/g in the liver of Dalmatian Pelicans collected in Karla reservoir (Greece) during summer 2016 by using immunological ELISA method. In the same study, significant differences were found between various waterbird tissues examined for MCs while detectable concentrations of saxitoxins and cylindrospermopsins were also recorded [71].…”

The Prespa Lakes area in Greece—comprised partly of lake Great and lake Lesser Prespa and the Vromolimni pond—has a global importance for biodiversity. Although the waters show regular cyanobacteria blooms, assessments of water quality threats are limited. Samples collected in 2012 revealed scattered and low microcystin (MC) concentrations in Great Prespa (<0.2 μg MC L−1) whereas considerable spatial heterogeneity in both total chlorophyll (2.4–93 µg L−1) and MC concentrations (0.04–52.4 µg MC L−1) was detected in Lesser Prespa. In 2013, there was far less spatial variability of MC concentrations in Lesser Prespa (0.4–1.53 µg L−1), however in 2014, increased concentrations were detected near the lakeshore (25–861 µg MC L−1). In Vromolimni pond the MC concentrations were on average 26.6 (±6.4) µg MC L−1 in 2012, 2.1 (±0.3) µg MC L−1 in 2013 and 12.7 (±12.5) µg MC L−1 in 2014. In 2013, no anatoxins, saxitoxins, nor cylindrospermopsins were detected in Lesser Prespa and Vromolimni waters. Tissue samples from carps, an otter and Dalmatian Pelicans contained 0.4–1.9 µg MC g−1 dry weight. These results indicate that cyanotoxins could be a threat to the ecosystem functions of particularly Lesser Prespa and Vromolimni.
