“…The PMPL index was specifically developed for Polish lakes and is currently still being tested. There are some studies of large-surface-area lakes [ 83 , 84 ], as well as small lakes of less than 50 ha [ 15 , 16 , 85 ]. In our study, as well as in previous studies, the results based on the PMPL, PSI, and Q indices were not consistent.…”

Phytoplankton is one of the five biological quality elements used in the assessment of the ecological status of surface waters according to the European Water Framework Directive established in 2000. In this study, we determined the ecological status of three small and shallow lakes in the Polesie Plain, Eastern Poland, by using indices based on phytoplankton assemblages. The predominant phytoplankton of all three lakes were filamentous cyanobacteria, both heterocystous and non-heterocystous, represented by the genera Aphanizomenon, Planktothrix, Limnothrix, and Planktolyngbya. We used the Hungarian Q index, German PSI (Phyto-See-Index), and recently developed PMPL (Phytoplankton Metrics for Polish Lakes) for Polish lakes. We compared the results from the calculation of the indices to physicochemical data obtained from the lake water and Carlson’s Trophy State Index (TSI). On the basis of TSI, Gumienek and Glinki lakes were classified as advanced eutrophic, whereas Czarne Lake had a better score and was classified as slightly eutrophic. The trophic state was generally confirmed by the ecological status based on phytoplankton indices and also showed the diverse ecological situation in the lakes studied. Based on the Polish PMPL, Gumienek Lake was classified as having bad status (ecological quality ratio (EQR) = 0.05), whereas Glinki and Czarne lakes were classified within the poor status range (EQR = 0.25 and 0.35, respectively). However, based on the German PSI, the lakes were classified in a different manner: the status of Gumienek and Czarne lakes was better, but unsatisfactory, because they were still below the boundary for the good status category recommended by the European Commission. The best ecological status for the studied lakes was obtained using the Q index: Gumienek Lake with EQR = 0.42 had a moderate status, and Czarne Lake with EQR = 0.62 obtained a good status. However, Glinki Lake, with EQR = 0.40, was classified at the boundary for poor and moderate status. Based on our study, it seems that the best index for ecological status assessment based on phytoplankton that can be used for small lakes is the Polish (PMPL) index.

The common planktonic green algal genus Nephrocytium was traditionally assumed to have a close relationship with the genus Oocystis and accordingly has been included in the family Oocystaceae. Although the position of Nephrocytium within the Oocystaceae has differed according to some authors over the years, its inclusion in the family has not been questioned. Following molecular studies of Oocystis, the Oocystaceae (including Nephrocytium) was removed from the class Chlorophyceae and placed in the Trebouxiophyceae. However, recent molecular studies of some of the former Oocystaceae members have returned them to the Chlorophyceae. These studies suggested the placement of Nephrocytium in the Sphaeropleales, but no taxonomic positioning within the order has been determined for the genus. The relocation of Nephrocytium agrees with a strong morphological traitit lacks the oocystaceaean multilayered ultrastructure of the cell wall. Based on molecular markers (18S rDNA and tufA), and optical and electron microscopy, the present study aimed to establish the relationships of the genus within the Sphaeropleales. The results support the recognition of a new family, the Nephrocytiaceae, to accommodate Nephrocytium. Furthermore, we have carried out a review of previously described Nephrocytium species and based on morphological and molecular data we propose the description of Nephrocytium vieirae sp. nov.

“…Cyanobacterial blooms have a negative impact on the functioning of aquatic ecosystems [26]. The taxa that achieved the highest abundance in Swarzędzkie Lake have been reported as commonly dominant in toxic water blooms from other Polish water bodies [27][28]. They have caused loss of diversity of organisms, decreased water transparency, etc.…”

Phytoplankton plays an important role in the structure and functioning of an aquatic ecosystem, thus affecting other groups of organisms [1]. The growth of phytoplankton depends mainly on the availability of nitrogen and phosphorus [2-4]. Excessive eutrophication caused by high nutrient concentrations (especially phosphorus and nitrogen) along with strong cyanobacterial blooms results in decreasing aquatic ecosystem biodiversity [5].
