Chara gymnophylla is one of the first charophyte species reported for Serbia during the late 19th and the early 20th centuries, and at that time it was the second in terms of the frequency of its occurrence in the country. General taxonomic misinterpretations in the past resulted in the concealment of another species, C. squamosa, within the findin...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: saprotrophic fungus Geastrum morganii, Guignardia istriaca and Hypoxylon howeanum, mycorrhizal fungus Amanita friabilis and Suillus americanus, xanthophyte Vaucheria frigida, stonewort Chara hispida, liverwort Calypogeia integristipula and R...

Ponds, the most numerous freshwater habitats globally, are becoming increasingly recognized as being important for rare, endemic and endangered species, owing to the high levels of biodiversity they support and their role in ecosystem services. However, they remain largely overlooked and widely excluded from policies that might protect them. Even t...

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...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: red algae Lemanea fucina and Paralemanea annulata, parasitic fungus Anthracoidea pratensis, saprotrophic fungi Cyathus olla, Massaria campestris, and Xylaria sicula, stonewort Chara canescens, liverworts Gymnomitrion commutatum and Porella b...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: red algae Lemanea rigida and Paralemanea torulosa, mycorrhizal fungi Amanita simulans and Terfezia pseudoleptoder-ma, parasitic fungus Microbotryum vinosum, saprotrophic fungus Sarcoscypha jurana, stonewort Chara tenuispina, mosses Brachythe...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: cyanobacteria Anagnostidinema amphibium, mycorrhizal fungus Tricholoma frondosae, stonewort Chara connivens, mosses Dicranum polysetum and Ulota intermedia, and dicots Eclipta prostrata, Paeonia daurica subsp. daurica, Ruta graveolens and So...

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 alterati...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: parasitic fungus Antherospora hortensis, saprotrophic fungi Loweomyces fractipes and Pholiota henningsii, stonewort Chara canescens, mosses Grimmia caespiticia and Rhodobryum ontariense, fern Woodsia alpina, monocots Aegilops triuncialis, Ep...

Biological assessment metrics 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 and water chemistry are often poor. This is seen as major weaknesses of Water Framework Directive-related monitoring and assessm...

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 b...

Charophyte species delineation is regularly based on a set of thallus morphological characteristics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. DNA barcoding may contribute to solving these challenges. Here we characterize Chara contraria with an unusual set of morphologi...

We here present a macrophyte index for assessment of lake eutrophication, tailored to Balkan lakes (Balkan macrophyte index, BMI).

Massive gravel excavation is one of the most destructive forces affecting riverine habitats in Europe. However, gravel pit lakes are also recognized as valuable wildlife refuge areas. Different hydromorphological characteristics of gravel pits may influence aquatic biota differently. Optimal selection of gravel excavation procedures may create favo...

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 analys...

Due to their specific physical and chemical properties of water and soil soda pans of the Vojvodina region represent a unique type of habitats. Salinity is a major structuring factor which strongly affects species richness. Many halotolerant, alkalotolerant and halophilic organisms, together with numerous eurytopic elements inhabit these kinds of e...

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 ha...

This paper summarises known data regarding floristic richness, distribution and habitat preferences of the charophyte algae (Charales) in the region of Vojvodina (Serbia). The historical records were collected from all available literature and herbarium data on charophytes in Vojvodina from the beginning of charophyte research in the 19 th century...

The study presented is an attempt to explain variance in charophyte presence for the territory of Serbia by using several environmental parameters and to find a connection between certain species of charophytes and aquatic macrophytes found growing with them. Environmental parameters used were habitat type, water depth, altitude and four bioclimati...

Floristic and taxonomic diversity, as well as studies of ecological characteristic of Charophyta algae were carried out within the complex biodiversity researches, in the Zasavica Special Nature Reserve. Nine species were recorded: Chara globularis, C. contraria, C. vulgaris, Nitella mucronata, N. capillaris, N. syncarpa, N. confervacea, Tolypella...
