We studied how ecological factors affect species composition and structure of soil algal assemblages in different types mountain tundra sparse forests the Northern Urals. Soil moisture, pH, nitrogen content amount solar radiation were determined using Ellenberg indicator values from phytoindicators. Species identification algae was made light microscopy following culture. identified 74 five divisions. Most Cyanobacteria Chlorophyta. For each habitat type we with high frequency fidelity....
For many years Chrysastrella Chodat has been a cyst genus but recently it re-instated and re-defined. Currently, contains Ochromonas-like flagellates including O. tuberculata Hibberd which was synonymized with the type species, paradoxa Chodat. A mass development of stomatocysts, we identified as Ch. paradoxa, observed in bog on territory “Yugyd va” National Park (the Subpolar Urals, Russia). The morphology stomatocysts studied by scanning electron microscopy compared previously described...
In this study, the cryptomonads of northern territories Russia were explored. Four strains isolated from different acidic habitats in Middle Urals and North European part Russia. Cells these are flattened dorsoventral plane, have an asymmetrical outline similar size shape to Cryptomonas erosa. Phylogenetic relationships inferred using maximum likelihood Bayesian interference datasets nuclear-encoded SSU, LSU, ITS2 rDNA psbA cpDNA show that form one clade, which was divided into three...
Abstract Ten rare species of macroscopic algae were found in freshwater ecosystems the Pechora and Vychegda River basins, belonging to four divisions: Cyanoprokaryota - 1 species, Rhodophyta 3, Chrysophyta 1, Charophy-ta 5. Some these included regional Red Data Books Nenets Autonomous District Komi Republic, others recommended be included. Areas distribution marked; development conditions limiting factors described.
Specific hydrological characteristics of small reservoirs and insufficiency data on them determinethe need for their integrate investigation to reveal the patterns ecosystems formation that could help estimate state in future monitoring.The article presents water chemistry main biological components (phyto -and zooplankton, zoobenthos, vascular plants, mosses) three situated middle taiga subzone Komi Republic.It was established hydrochemical flora fauna species composition reflect regional...
Based on scanning electron microscopy, frustule morphology of the diatoms Kobayasiella subtillissima, K. parasubtillissima and okadae from dystrophic weakly mineralized water bodies in northeastern European Russia (the Komi Republic Vologda Region) was studied. The ranges variation valve length width stria density for subtillissima coincided with published data these species are different due to interpopulation variability. Taxonomic assessment characters also made. New records оkada allowed...
The paper presents the results of SEM study morphological variability diatoms Kobayasiella subtilissima (Cleve) Lange-Bertalot, K. parasubtilissima (H. Kobayasi et Nagumo) Lange-Bertalot and okadae (Skvortsov) Lange-Bertalot. Algae samples were taken in Lake Bolotnoye (northeast European part Russia) Shichengsky Swamp (Vologda Region, Russia). range variation length width valves number striae 10 μm coincide with published data. In okadae, exceed literary our is less, possibly due to...
The purpose of the data paper was to introduce into scientific literature results work carried out for third edition 'Red Data Book Komi Republic'. article reflects methodological approaches formation a list rare and in need protection species describes corresponding datasets published GBIF.Information about 7,187 occurrences 438 infraspecies included Republic' have been published.
The paper is based on the dataset whose purpose was to deliver, in form of GBIF-mediated data, diverse materials biodiversity a large mire, Shichengskoe mire (Vologda Region, north-western Russia), including its various sites and intra-mire water bodies. our collected for two decades (from 2000 2021) different parts biotopes complemented by scarce data obtained previously other researchers. contain diversity Animalia (2886 occurrences), Bacteria (22), Chromista (256), Fungi (111), Plantae...
Abstract Species diversity of algal communities sphagnum epiphyton was studied in six mountain and plain mires the Subpolar Urals (Russia). A total 154 species intraspecific taxa from divisions were identified. The highest richness recorded for Bacillariophyta (96 taxa) Charophyta (33) divisions. Kobayasiella parasubtilissima, Tabellaria flocculosa Eunotia lunaris had high abundance. Dominant often formed by lunaris, E. mucophila, parasubtilissima Pinnularia subcapitata. CCA analysis showed...
Bertalot и K. okadae (Skvortsov) Lange-Bertalot с помощью сканирующей электронной микроскопии.Образцы водорослей отбирали в оз.Болотное (cеверо-восток европейской части России) Шиченгском болоте (Вологодская обл., Россия).Диапазон изменчивости длины ширины створок, число штрихов 10 мкм у subtilissima parasubtilissima совпадают литературными данными.У
Stomatocysts of Chrysastrella paradoxa was observed in a herb-mosses mire on the territory “Yugyd va” National Park (the Subpolar Urals, Russia). The morphology stomatocysts studied by scanning electron microscopy. This is second record Ch. Russia.
In epiphyton of the Shchugor River 143 species (with varieties and forms) diatoms from 49 genera, 21 families were identified. Families Fragilariaceae Achnanthidiaceae, Gomphonemataceae, Naviculaceae, Bacillariaceae, Eunotiaceae include 10 more taxa. Genera Gomphonema (11), Eunotia, Nitzschia (10 species) are predominate. Diatoms on mosses most abundant diverse. Common all macrophytes Achnanthidium minutissimum (Kützing) Czarnecki, Cocconeis placentula Ehrenberg, Encyonema minutum (Hilse)...
The first data on algae from some aquatic and terrestrial ecosystems of the southern taiga territory Koigorodsky National Park (Komi Republic, Russia) showed a fairly diverse composition these organisms: in park, 194 taxa were identified with intraspecific varieties forms six divisions significant predominance representatives Bacillariophyta (68%); forest phytocenoses, 27 rank below genus soil four seven classes found, mainly Chlorophyta division (63%). Three new species found for European...
