AB  - This study presents a newly discovered site of Lychnothamnus barbatus, one of the rarest charophytes worldwide of a disjunctive, Euro-Australasian-American distribution. The species is the only representative of the genus Lychnothamnus on a global scale, hence its threat poses a risk of extinction to the entire lineage. In June 2019, Lychnothamnus barbatus was discovered in Lake Malo Blato, a north-western bay of Lake Shkodra/Skadar, to be a new element to the flora of Montenegro. Lychnothamnus barbatus was recorded at a depth of 3 m, in nutrient-poor but calcium-rich water and on a muddy substrate in the zone of submerged vegetation composed of charophytes and angiosperms. The collected thalli of L. barbatus were young and sterile, green, slightly calcified, and up to 15 cm high. Except for gametangia, all features which are diagnostic for this rare charophyte were well developed. Based on the synthesis of the current state of knowledge, the new site of L. barbatus is presented in the context of the species’ ecological requirements and climatic plasticity, current distribution, and history in the Balkans.

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  - Along six transects in each of six lakes across the Western Balkans, we collected data for three groups of littoral biological water quality indicators: epilithic diatoms, macrophytes, and benthic invertebrates. We assessed the relationships between them and three environmental pressures: nutrient load (eutrophication), hydro-morphological alteration of the shoreline, and water level variation, separating the effect of individual lakes and continuous explanatory variables. Lake water total phosphorus concentration (TP) showed substantial variation but was not related to any of the tested biological indicators, nor to any of the tested pressures. We suggest that this may be due to feedback processes such as P removal in the lake littoral zone. Instead, we found that a gradient in surrounding land-use towards increasing urbanization, and a land-use-based estimate of P run-off, served as a better descriptor of eutrophication. Overall, eutrophication and water level fluctuation were most important for explaining variation in the assessed indicators, whereas shoreline hydro-morphological alteration was less important. Diatom indicators were most responsive to all three pressures, whereas macrophyte biomass and species number responded only to water level fluctuation. The Trophic Diatom Index for Lakes (TDIL) was negatively related to urbanization and wave exposure. This indicates that it is a suitable indicator for pressures related to urbanization, although a confounding effect of wave exposure is possible. Invertebrate abundance responded strongly to eutrophication, but the indicator based on taxonomic composition (Average Score Per Taxon) did not. Our results suggest that our metrics can be applied in Western Balkan lakes, despite the high number of endemic species present in some of these lakes. We argue that local water management should focus on abating the causes of eutrophication and water level fluctuation, whilst preserving sufficient lengths of undeveloped shoreline to ensure good water quality in the long run.

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  - In Europe, macrophytes have for a long time been used as indicators of eutrophication and for the assessment of ecological status of lakes. Almost twenty assessment systems were developed in the last years, but most of them focused on lakes in Northern and Central Europe. The Mediterranean region, and especially the Balkan, lag behind, probably because of the relatively small number and high variability of natural lakes and the lack of collaboration among Balkan countries. The Balkan macrophyte index (BMI) we developed is designed to assess eutrophication in lakes in the Balkan region. The data we used were gathered in six Balkan lakes: Ohrid, Prespa, Lura, Biogradsko, Crno and Sava, located in Macedonia, Albania, Montenegro and Serbia. Submerged aquatic vegetation, water chemistry and sediment total phosphorus were analysed. Our results show that calculating a macrophyte index can be a problem in lakes with water level fluctuations of several meters, because the macrophyte vegetation may be absent or these lakes are dominated by “oligotrophic” or “eutrophic” species. Even though the number of lakes was small in our study, the BMI was loosely related to water phosphorus concentrations. If we analyse a larger number of lakes using the same methods, reference conditions and status class boundaries may be derived from the phosphorus BMI regression.

AB  - Charophytes or stoneworts (Charales, Characeae) are submerged green macroscopic algae of great importance for the environmental and economic sustainability of the aquatic ecosystem of Lake Skadar/Shkodra. In the course of many years of research of these algae in the Montenegrin and the Albanian part of Lake Skadar/Shkodra, 30 taxa of charophytes have been registered in the rank of species, forms and varieties. These taxa belong to the four genera of the Characeae family existing in the lake – namely, Chara, Nitella, Tolypella and Nitellopsis. The largest number of taxa belongs to the genus Chara, namely, 12 species, 3 forms and 2 varieties, 10 species belong to the genus Nitella, 2 species belong to the genus Tolypella and, finally, only 1 species belongs to the genus Nitellopsis. The ecological and phytocenological characteristics of each taxon, as well as the hydrological and geomorphological characteristics of their finding sites, are presented in order to emphasize the fact that Lake Skadar/Shkodra is one of the most significant charophyte diversity centres in the Balkan Peninsula. All the data presented in this study are based on our own field investigations, as well as herbarium and literature surveys.
