“…Achnanthidium caledonicum, which predominated in the majority of periphyton samples from the Vrutci Reservoir, is characterized as a vulnerable species in the German Red List [23,24], and our data provide a valuable record on the ecology and distribution of this species. A. caledonicum is described as common in circumneutral and slightly alkaline waters with low nutrient concentration [32]. This species is expected in chalk-rich and nutrient-poor lentic ecosystems in mountainous regions, and is an indicator of good ecological quality [24], thus their presence and abundance in the Vrutci Reservoir can be discussed.…”

“…As the Vrutci Reservoir is situated between two mountains, Tara and Zlatibor, in western Serbia, and is moderately chalk-rich, it seems like a perfect habitat for A. caledonicum. Still, the Vrutci Reservoir's trophic status as regards phosphorous is higher than expected for the habitat of A. caledonicum [32,24]. On the other hand, Pantocsekiella ocellata, as the species that shared dominance with A. caledonicum in the Vrutci Reservoir, is a typical oligosaprobic species distributed in oligo-to slightly eutrophic ecosystems [24,33].…”

Despite their unique ecology and implications for ecological assessment, diatoms in lentic ecosystems are still insufficiently studied in both scientific research and operational monitoring. In particular, the ecology of periphytic diatoms relative to the global expansion of cyanobacterial blooms in lakes has not been described at all. This study aims to describe the diversity and dynamics of a periphytic diatom community in the Vrutci Reservoir during Planktothrix rubescens bloom, and to evaluate the adequacy of standard diatom index implementation in lentic ecosystems relative to the diatom index adapted for lakes-the Trophic Diatom Index for Lakes (TDIL). The study was conducted in the Vrutci Reservoir in western Serbia. Periphyton was developed on an artificial glass substrate during the summer of 2015, following a depth gradient of a stratified water column. Diatom diversity and abundance, as well as diatom indices were estimated. Discounting the cyanobacterial bloom, 79 taxa of diatoms were recorded and among them the species Aneumastus stroesei as the first representative of the entire genus Aneumastus ever to be detected in Serbia. Diatom distribution along the depth gradient was clearly associated with shifts in environmental conditions. TDIL showed an advantage over standard diatom indices in terms of stability during experimental period and uniformity along the depth gradient, indicating the necessity for further testing of this index performance in lakes, and consequently local water-quality legislation update.

Diatoms were collected from the Kotulpur area of West Bengal. Four diatom taxa, namely, Eunotia minor (Kützing) Grunow, Achnanthidium minutissimum (Kützing) Czarnecki, Lemnicola hungarica (Grunow) Round and Basson, and Navicula radiosa Kützing were observed using scanning electron microscopy (SEM) and identified in light of modern diatom taxonomic trends. Except Eunotia minor, all these taxa are new records to Eastern India. A note on the taxonomy of Achnanthes pseudobiasolletiana as described by Gandhi and Eunotia serrata var. diadema (Ehr.) R. M. Patrick as reported by Dwivedi and Misra has been added.

“…The genus Achnanthidium has been subdivided into three subgroups, the "Achnanthidium minutissimum complex", "A. pyrenaicum complex" and the "A. exiguum complex" (Karthick et al 2017;Pérès et al 2014;Wojtal et al 2011;Wojtal et al 2010). The A. minutissimum complex has straight external distal raphe ends and, usually, linear to linear-lanceolate valve shapes, striae density increasing towards the apices and round external areolar openings (Pinseel et al 2015;Compère & Van De Vijver 2011).…”

We describe three new Achnanthidium species, A. lacustre sp. nov., A. sublanceolatum sp. nov., and A. taipingensis sp. nov., from Taiping Lake, Anhui Province (China) based on light and scanning electron microscopy. A. lacustre sp. nov. belongs to the "A. minutissimum complex" of the genus, based on it having straight external distal raphe fissures and round to elliptical areolae. Both A. sublanceolatum sp. nov., and A. taipingensis sp. nov. belong to the "A. pyrenaicum complex" of the genus, based on them having transpically-elongated areolae and deflected external distal raphe fissures. All three species are sufficiently different from other similar species based on valve outline, shape of the axial and center areas, and striae density. These three new species are all observed in benthic collections from Taiping Lake.
