Abstract:

From the Netherlands, three desmid species are newly described to science: Actinotaenium spinosporum (with zygospores), Staurastrum brachiatoides (with zygospores) and Staurastrum quadriradiatum. In addition to that, zygospores of the rather rare species Staurastrum echinatum are described for the first time. Differences with similar-looking species are discussed.

Abstract:

Staurastrum is a microalgae from the family of Desmidiaceae which is abundant in freshwater. The purpose of this study was to determine the diversity of Staurastrum and the abundance of the population of Staurastrum in the Sentani Lake Jayapura. The study was conducted in March 2018 in the Sentani Lake Jayapura. The sampling method used was the survey method by sampling water in 6 locations (Kampung Yakonde, Ifale, Hobong, Kalkhote, Ayapo, Puay) on the edge and center of the lake. The results showed that 4 species of Staurastrum on the Sentani Lake were S. arachne, S. diacathum, S. gracile and

Abstract:

Interspecific competition for phosphorus between the blue-green alga Anabaena flos-aquae and the green alga Staurastrum luetkemuelleri was studied in enclosure experiments. Both algal populations increased in number upon introduction of fish, but addition of herbivorous zooplankton led to an increase solely in the Staurastrum population. This could not be attributed to grazing by zooplankton, chemical or physical conditions (light, pH, inorganic carbon), or the total supply or rate of supply of phosphorus. The observed differences were apparently due to the patchy release of phosphorus by the

Staurastrum pantanale is proposed new to science and is characterized by its crenate cell wall and cell dimensions. The species was collected from the metaphyton of a shallow tropical lake (SalitradaCampoDoraLake, 18º 58’ 02” S, 56º 38’ 59” W) with transparent water and pH 5, located in the Nhecolândia Pantanal, Mato Grosso doSul State,Brazil. The new species’ morphology and relationship with morphologically close species are discussed.

From the Netherlands, four desmid species are described as new to science: Cosmarium pseudodifficile, Cosmarium pseudoformosulum, Cosmarium pseudoreniforme, and Cosmarium turpiniiforme. Cosmarium jelskii was rediscovered after approximately a hundred years, Euastrum ansatum var. dideltiforme f. elongatum is raised to Euastrum ruzickae and Tetmemorus flensburgii is separated from Tetmemorus brebissonii. Differences with similar-looking species are discussed. In addition, zygospores of Staurastrum pileolatum are depicted for the first time.

Abstract Fourteen thermokarst lakes and one mountain lake were explored in the study period. A total of 116 species of desmids belonging to 22 genera were identified. The genera Cosmarium (29), Staurastrum (18) and Closterium (13) were most abundant. The highest number of species (88) was recorded in the habitats with Sphagnum and brown mosses. Twenty-seven species and one variety of desmids were observed for the first time in the Polar Ural Mountains.
