AB  - The Sava Lake, originating from a branch of the Sava river, is situated next to
the island Ada Ciganlija on the right bank of the Sava river in Belgrade (Serbia). It
is an urban recreational lake under strong anthropogenic influence, especially during
the summer days. Investigations of aquatic vegetation were conducted several times
during the last decades and the latest systematic survey was conducted in summer
2017 as a part of STARWALK project. Since then, sampling was continued
sporadically, revealing a great diversity of charophyte algae. Overall,we discovered
eight charophyte species in the lake, which is a remarkable number even for
unimpacted natural lakes. The species found belong to four out of six genera of
living charophytes. The genus Chara is represented with three species, C.
globularis, C. contraria and C. virgata, the genus Nitella also with three, Nitella
mucronata, N. gracilis, N. flexilis, and genera Tolypella and Nitellopsis with one
species, respectively, T. intricata and N. obtusa. Moreover, almost all discovered
species are red listed in Serbia and the Balkans, according to IUCN criteria. Six of
them are strictly protected according to national legislation. The finding of Nitella
flexilis was the first finding of this species for Serbia.

AB  - Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. DNA barcoding may contribute to solving these chal- lenges. Here we characterize Chara contraria with an unusual set of morphological character- istics, and specimens morphologically resembling Chara connivens collected in Serbia, by describing their morphological traits and analysing matK barcoding results. Our results indi- cated that dioecious Chara specimens, tentatively determined as Chara “connivens” based on morphological traits, were genetically more closely related to C. globularis. These Chara
“connivens” specimens formed a sister group to a monophyletic C. globularis cluster, suggesting that it may be neither C. connivens nor C. globularis. We strongly encourage further barcoding of C. “connivens” samples from freshwater, in order to find out if there are consistent genetic differences between the dioecious freshwater C. “connivens” and monoecious C. globularis. Barcoding of matK placed the monoecious Chara specimens, which based on morphological characteristics initially were determined as C. virgata, into the C. contraria group. This indicates that the microscopic traits which commonly are used for Chara species determination some- times are misleading. In general, our study challenges the commonly used phenetic species concept in Charophyte taxonomy and illustrates the importance of molecular approaches to evaluate the validity of morphological characteristics of the plant thallus in species delineation.

AB  - Biological assessmentmetrics and water chemistry measurements are used to quantify the link between stressors
and their effects on lake ecosystems, for the Water Framework Directive. However, correlations between metrics
andwater chemistry are often poor. This is seen as majorweaknesses ofWater Framework Directive-relatedmonitoring
and assessment.We analyzed macrophytes, benthic algae, benthic macroinvertebrates, water chemistry
and sediment total phosphorus content in the littoral of six lakes in the Western Balkans and used CORINE land
use data to estimate nutrient enrichment via runoff from the adjacent land. Lakes with a higher estimated phosphorus
runoff fromthe adjacent land did not have higher littoralwater nutrient concentrations, but littoral diatom
assemblages indicated more eutrophic conditions. These lakes also had higher abundances of littoral benthic primaryproducers,
which in turnwere associatedwithlowconcentrations of dissolved nutrients, but only in autumn,
not in spring. This is consistent with primary producers taking up nutrients during the summer growth season. In
lakeswith high abundances of benthic primary producers, it is likely that the littoral vegetation plays a large role in
the transfer of nutrients from the water to the benthos. This process impairs correlations between biological metrics
and water nutrient concentrations. Our results suggest that CORINE land cover may be more useful to characterize
littoral nutrient enrichment than lake water chemistry. Increased benthic primary producer biomasses and
“eutrophic” diatom indicesmay indicate littoral nutrient enrichment even ifwater nutrient concentrations are low

AB  - Aquatic plants have long been used as indicators for nutrient enrichment in lakes. In the Mediterranean, however, the process of developing and intercalibrating macrophyte assessment methods for lakes has lagged behind Northern and Central Europe, likely due to the relatively small number and high variability of natural lakes in the Mediterranean but also because of the different monitoring traditions in different parts of Europe. We here present a macrophyte index for assessment of lake eutrophication, tailored to Balkan lakes (Balkan Macrophyte Index, BMI). We analysed submerged aquatic vegetation, water chemistry and sediment total phosphorus content at several sites in lakes Prespa, Ohrid, Lura, Biogradsko, Crno and Sava, located in Albania, North Macedonia, Montenegro and Serbia. Despite the restricted number of lakes in our dataset, the BMI was loosely related to water phosphorus, rather than nitrogen, concentrations. Our results show that macrophyte indices may not be applicable in lakes experiencing annual water level fluctuations of several meters, because the macrophyte vegetation in such lakes may be absent, or alternatively dominated by “oligotrophic” or “eutrophic” species. Once a larger number of lakes has been analysed using the same methods, reference conditions and status class boundaries may be derived from the phosphorus – BMI regression.

AB  - Great Lake is the largest of 14 lakes situated in Lurë National Park, in the eastern part of the Lurë Mountains, Albania. To characterize lake ecological status, epiphytic and epilithic diatom samples were collected from the lakeshore in summer 2005, 2013, and 2017. However, in 2017 no macrophytes were present, such that only epilithic diatom samples could be collected. After laboratory analysis, 52 diatom taxa were identified in July 2005, 67 in June 2013, 111 in August 2013, and 126 in August 2017. The genera Diatoma, Epithemia, Fragilaria, and Surirella were not recorded in 2017, contrary to previous years.We applied two diatom indices to asses the ecological status of the Great Lake, IPS (Indice de Polluo–sensibilité), and TDIL (Trophic Diatom Index for lakes). The IPS index indicated very good water quality in all years, while the TDIL indicated moderate water quality in 2005 and 2013 and good water quality in 2017. Because more species have indicator values for calculating the IPS than the TDIL (valve number used to calculate the IPS was above 95%, while for TDIL was below 50% of 400 counted valves), the IPS may be a more promising tool for bioindication of lakes in Albania according to the demands of the Water Framework Directive.

AB  - During 2016-2017 six Balkan lakes were investigated: Sava Lake in Serbia, Ohrid Lake and Prespa Lake in North Macedonia and Albania, Great Lake in Albania, Biogradsko Lake and Crno Lake in Montenegro. Epilithic diatom samples were collected from 6 localities around each lake with the aim to test the applicability of diatom indices for ecological assessment of Balkan lakes. Also, water samples for chemical analysis were taken. Based on the concentrations of total phosphorus and BOD (biochemical oxygen demand) two lakes (Ohrid and Crno) were oligotrophic and oligosaprobic, while the other four lakes were mesotrophic and β-mesosaprobic, respectively. The highest diversity of dominant taxa was recorded in Ohrid and Prespa, and one of the dominant taxa was the endemic species Gomphonema paratergestinum. Diatom communities in lakes Sava and Crno were dominated by Achnanthidim minutissimum and Encyonopsis microcephala. According to Serbian legislation, the IPS index is used for the assessment of the ecological status of lakes, while in North Macedonia, Albania and Montenegro National Monitoring Systems do not yet include officially accepted diatom indices. In our results, the diatom indices IPS and IBD had the highest inclusion of diatom taxa, in some lakes almost 100%. The lowest inclusion of diatom taxa had the TDIL index. Values of IPS and IBD indices indicated very good water quality for Great Lake, Crno and Biogradsko, and good for Prespa. The water quality of Ohrid and Sava was between very good and good. Values of trophic indices (Rott TI and TDIL) indicated a very low concentration of nutrients in the Sava, Great Lake and Biogradsko, low in Ohrid and Prespa and low to the very low concentration of nutrients in Crno. The development and establishment of monitoring systems in lakes according to the requirements of the Water Framework Directive (WFD) is essential for all European countries and more comprehensive ecological investigations of Balkan lakes are necessary to be able to fulfill these demands.

AB  - Sava Lake was created from the right arm of the Sava River, and the inhabitants of Belgrade use the lake intensively for swimming and bathing. We analysed macrozoobenthos and epilithic diatom communities at six sites from April to October 2017, to assess the ecological status of Sava Lake according to the National legislation of Serbia. Considering macrozoobenthos communities, the mean values of Zelinka and Marvan saprobity index indicated high ecological status. In contrast, results obtained from the mean values of BMWP (Biological Monitoring Working Party) scores suggested moderate to poor ecological status. The mean values of the IPS diatom index (Indice de Polluo-sensibilité) indicated high ecological status, while the TDIL index (Trophic Diatom Index for lakes) was slightly more sensitive and indicated good ecological status. Water chemical parameters indicated that Sava Lake was mainly oligotrophic during the study period (average total phosphorus concentrations were 10.7 μgL-1 and average total nitrogen concentrations 410 μgL-1). Before being able to adopt an integrative approach for ecological status assessment (combining two or more biological quality elements), more studies must be performed on how to choose the most sensitive and adequate indices. This is especially true for lakes experiencing intensive anthropogenic pressure during the summer season. Also, the boundary values in the National legislation of Serbia must be adapted for lakes, such as Sava Lake.

AB  - Most field charophytologists have experienced that the morphology of Chara specimen can be intermediate” between two different species. We collected a Chara sample in lake Sava, close to Belgrade, Serbia. The habitus of this specimen resembled C. contraria, but the microscopic details (“spines”, stipulodes) resembled C. virgata. Preliminary analysis of the matK gene, however, clearly place the sample into C. contraria. This means that C. contraria sometimes may have stipulodes where only the upper row is elongated. We also collected a sample which orphologically resembled C. connivens in Dulin pond (44°51’11.5” N 21°17’52.2” E), Serbia. The sample was clearly dioecious, and we analysed male and female samples. Preliminary analyses of the matK gene placed this sample into a separate sub-cluster of C. globularis (i.e. not together with C. connivens, but an own sub-group within C. globularis). We will present the most recent results on these specimens.

AB  - Over the past decade a great number of new diatom taxa was described, as well as re-definitions and delimitations of taxa from different species complexes have been performed. The reasons for the constant increase in the number of described diatom taxa are numerous: unexplored habitats, improved light microscope resolution and digital cameras with accompanying softwares, scanning electron microscopy, molecular studies. For most of the newly-described species only morphological characteristics are known. What about their ecological preferences?
OMNIDIA is a widely used software for evaluation of ecological status of water bodies based on diatoms. The database from the first version of the software up to today has grown from 2035 to more than 23.000 diatom taxa. However, for the most newly-described taxa there are no indicator values.
In our study we evaluated the ecological status at six sites in lakes Ohrid and Prespa, respectively, based on different biological quality elements (diatoms, macrozoobenthos and macrophytes) as well as water chemistry. In two out of six sites in lake Ohrid, and five out of six sites in lake Prespa, Gomphonema paratergestinum was a dominant or subdominant species (33.5-69.66 % in Ohrid Lake and 9.95-65.34 % in Prespa Lake). In the OMNIDIA software, there currently are no indicator values for G. paratergestinum. However, the very similar species G. tergestinum has well known indictor values. G. paratergestinum resembles G. tergestinum with respect to some morphological characteristics (e.g. valve outline), but can be differentiated by the stria density. Both species were present in lakes Ohrid and Prespa, however, with dominance of G. paratergestinum. Based on the diatoms recorded at a site, OMNIDIA calculates diatom index values. How could G. paratergestinum with abundances up to 69.66 % influence diatom indices? If we “experiment” and substitute G. paratergestinum with G. tergestinum, the obtained diatom index values indicated a completely different ecological quality class.
Every newly-described species is important since it increases our knowledge about diversity, biogeography and distribution of diatoms. However, there still is a gap between taxonomy and biomonitoring. How can we overcome this problem? According to the Botanical Nomenclature Code for algae, fungi, and plants no note or suggestion regarding ecology or ecological preferences of a species is required for description. Maybe, a possible solution could be that in the description of the species ecological data, such as pH, conductivity, total phosphorus, concentrations of different anions etc. should be included. Scientists today join forces to review material and species collected by Kützing, Ehrenberg, Grunow, Van Heurck, Cleve etc... In the same way ecological data of newly-described species could be assembled and their indicator values calculated.

AB  - Great Lake is the largest of the 6 lakes situated in the eastern part of Lura Mountain in the Lurë National Park. Samples were collected in July 2005, June and August 2013 and August 2017. In 2005 and August 2013 epiphytic samples were collected from one locality, while in Jun 2013 was collected epilithic sample. However, in August 2017 no macrophytes were found which caused the collection of epilithic samples from 6 localities (LM1-LM6) around the lake with the aim of establishing ecological status. After laboratory analysis 52 taxa were identified in July 2005, 67 in June 2013 and 111 in August 2013. In August 2017 the number of identified taxa was higher, in total 126 taxa. Dominant taxa in July 2005 were Achnanthidium minutissimum (13.01%), Diatoma vulgaris (13.84%) and Meridion circulare (11.76%). A. minutissimum was also dominant in 2013 (22.26% in June and 21.48% in August). In 2017, dominant taxa differed among localities: LM1 Cyclotella cretica var. cyclopuncta (29.38%), LM2 and LM3 Encyonopsis microcephala (21% at both sites), LM4 Cyclotella cretica var. cyclopuncta (17.41%) and Encyonopsis krammeri (18.91%), LM5 and LM6 A. minutisimum (27.79% and 30.47%, respectively). The genera Diatoma, Epithemia, Fragilaria and Surirella were not recorded in 2017, contrary to previous years. The ecological status of the Great Lake was assessed by using diatom indices. Most European countries have established lake assessment systems based on diatoms. However, the Albanian National Monitoring System does not include biological parameters and therefore no officially accepted diatom index is in place. We compared the values of IPS (Indice de Polluo-sensibilité) and TDIL (Trophic Diatom Index for lakes) indices using boundary values given by the authors. Values of IPS index indicated very good water quality in all years at all sites, while the TDIL indicated moderate water quality in 2005 and 2013 and good water quality in 2017. The reason for this deviation probably is the low relative abundance of indicator species used to calculate TDIL index. The TDIL was developed 2007 in Hungary, and it includes significantly fewer indicator taxa than the IPS. More comprehensive ecological investigations of lakes in Albania are necessary to be able to fulfill the demands of the Water Framework Directive.

Dominant taxa in July 2005 were Achnanthidium minutissimum (13.01%), Diatoma vulgaris (13.84%) and Meridion circulare (11.76%). A. minutissimum was also dominant in 2013 (22.26% in June and 21.48% in August). In 2017, dominant taxa differed among localities: LM1 Cyclotella cretica var. cyclopuncta (29.38%), LM2 and LM3 Encyonopsis microcephala (21% at both sites), LM4 Cyclotella cretica var. cyclopuncta (17.41%) and Encyonopsis krammeri (18.91%), LM5 and LM6 A. minutisimum (27.79% and 30.47%, respectively). The genera Diatoma, Epithemia, Fragilaria and Surirella were not recorded in 2017, contrary to previous years. The ecological status of the Great Lake was assessed by using diatom indices. Most European countries have established lake assessment systems based on diatoms. However, the Albanian National Monitoring System does not include biological parameters and therefore no officially accepted diatom index is in place. We compared the values of IPS (Indice de Polluo-sensibilité) and TDIL (Trophic Diatom Index for lakes) indices using boundary values given by the authors. Values of IPS index indicated very good water quality in all years at all sites, while the TDIL indicated moderate water quality in 2005 and 2013 and good water quality in 2017. The reason for this deviation probably is the low relative abundance of indicator species used to calculate TDIL index. The TDIL was developed 2007 in Hungary, and it includes significantly fewer indicator taxa than the IPS. More comprehensive ecological investigations of lakes in Albania are necessary to be able to fulfill the demands of the Water Framework Directive.",
