“…50/10 µm). Previous studies registered N. wellneri with a larger range in size (8.5-15 µm long and 3-4.5 µm wide in Potapova et al 2003;11.8-16.6 Considering the central area, its symmetry, shape, size, and extent are important morphological features within Nupela (see Siver et al 2007;Wojtal 2009;Bahls 2011;Yu et al 2017;Genkal & Yarushina 2018;Rybak et al 2020). The central area unilaterally reaching the margin, consistently observed in N. The proposition of the new species is supported by observations in our populations compared to descriptions of other Nupela taxa provided in the literature.…”

During a survey on freshwater epilithic diatoms from subtropical lotic environments belonging to the Cascavel River microbasin, Paraná State, Brazil, we observed populations of a new Nupela Vyverman et Compère species. Morphological and meristic analyses were performed using light and scanning electron microscopy, resulting in the description of Nupela semifasciata sp. nov. This species is characterized by elliptic-lanceolate valves containing subcapitate apices in larger individuals and broadly rostrate-rounded apices in smaller ones, while the length/width ratio gradually decreases as the individuals become smaller. The central area unilaterally reaches the margin and always interrupts the row of areolae on the valve mantle. The valve mantle is externally composed of a second row of areolae near the apices. We cross-checked information with similar Nupela taxa, highlighting the main features that separate them. Nupela semifasciata was found in streams with acidic-neutral pH, low conductivity and low to high nutrient concentrations.

“…However, most studies of terrestrial diatoms are focused on areas of Europe and polar regions [23]. Therefore, it can be expected that the real number of terrestrial species is substantially higher, which seems to have been confirmed recently by taxonomic investigations covering both Europe [28][29][30][31] and tropical zones [32][33][34][35][36][37].…”

The aim of the study was to determine the effect of fertilization with various doses of ash from biomass combustion (balanced to the amount of K2O introduced into the soil) on the growth of representatives of soil microorganisms, i.e., diatoms. In a one-factor field experiment (control, NPK, 100, 200, 300, 400, 500 kg/ha), soil samples were collected from the 0–5 cm layer of podzolic soil under the cultivation of winter oilseed rape (Brassica napus L. var. napus) at the end of August 2019 and 2020. The biomass combustion ash used for soil fertilization was characterized by an alkaline reaction (pH = 12.83 ± 0.68) and high levels of basic macroelements required for proper plant growth and development. The particle size distribution in each plot was identified as loamy silt (pgl). Before the experiment (autumn 2018), the soil exhibited an acidic reaction (pHH2O = 5.8), low conductivity (EC = 68 µS), and 19.09% moisture at the 0–5 cm level. In total, 23 diatom species were identified in the material collected from the topsoil in all variants of the experiment. Hantzschia amphioxys, Mayamaea atomus, Mayamaea permitis, Nitzschia pusilla, Pinnularia obscura, Pinnularia schoenfelderi, and Stauroneis thermicola were the most abundant populations.

Also, a lot of new diatom species were described from Indonesian freshwaters over the last two decades ( Bramburger et al 2006 ; Kociolek et al 2018 ; Kapustin et al 2019 , 2021 ; Kulikovskiy et al 2019 ; Rybak et al 2019 ), including two new Achnanthidium species ( Tseplik et al 2021a , b ).

A new species, Achnanthidium bratanense, is described from Lake Bratan, located on the island of Bali (Indonesia). The morphology of this species was analyzed with light (LM) and scanning electron microscopy (SEM). A. bratanense is characterized by linear-elliptic to nearly elliptic valves with convex margins and rounded, broadly subcapitate apices. The striae of this species are hardly discernable under LM; they are weakly radiate throughout the valve and composed of one to four large transapically elongated areolae of different length and shape. The most similar taxon to A. bratanense is A. macrocephalum, a species described from Sumatra, another Indonesian island. The differences of A. bratanense from similar taxa are discussed.
