“…Total species list of the Pamir diatom flora was compiled in first time 12 from our study of the mineral and thermal springs as well as from referenced lists in publications about diatom diversity in Pamir aquatic habitats. 2,3,[5][6][7][8][9][10][11] All collected taxonomic data was adapted to the modern taxonomic system with help of algaebase.org. Taxonomic list was analyzed in the Microsoft Access 2013 Program.…”

“…10 Our own study of diatoms in thermal and mineral springs is enriched the regional diversity by 134 diatom species (166 with infraspecific taxa). 11 We assume that the diversity of this group of algae in Pamir is still far from complete. Altogether 558 taxa of diatom algae are known in Pamir aquatic habitats as a result of references collecting data and our own research.…”

Paper represents the first results of bioindication analysis of water quality in the Pamir aquatic habitats including rivers, lakes, mineral and hot springs with help of diatom algae. Altogether 438 bioindicators taxa were revealed from 558 known diatom algae in Pamir. Twelve environmental properties were assessed with help of species autecology. Bioindication analysis was doing for environmental parameters of water temperature, pH, salinity, and oxygen saturation as well as was assessed substrate preferences and nutrition type of diatoms, trophic state of water bodies and water quality on the base of organic pollution indications. We was find that diatoms in Pamir are strongly autotrophes, benthic or plankto-benthic inhabitants that preferred lowsaline, low-alkaline, middle oxygenated clear fresh water with low organical pollution and oligo-to meso-eutrophic state. Compative floristics of Pamir and surrounding diatom floras let us to assume that studied algal flora can represent regional reference area for close related high mountains habitats.

The first results of bioindicative analysis of water quality in the high-mountainous lakes of the Artabel Lakes Natural Park are presented using diatom species. A total of 95 diatom taxa collected in August 2013 and 2016 were identified and used as bioindicators for ten environmental variables. Bioindication, statistical methods and comparative floristic results show that the waters in all the lakes studied were fresh, low-saline, with circum-neutral pH and organically uncontaminated. The results of bioindication can be used as etalons for future monitoring of lakes in order to protect species found in the natural park, and can also be included in the national system of water quality standards in Turkey.

A diatom analysis of a peat deposit from Shemya Island (Aleutian Arc, USA) is performed, and the dynamics of the diatom community are described. According to the radiocarbon dating, the formation of the deposit began 9300 cal. years BP. Principal component analysis made it possible to relate the dynamics of the diatom community to certain environmental conditions and the factors that influenced the coastal ecosystems during its formation. The following factors (predictors) were considered: the influence of age, zoo- and anthropogenic effects, and changes in climatic conditions. Sea level change was the main driver of the diatom community in the studied water body having a continuous direct and indirect influence on the studied small water body, i.e., by bird colony formation and more humid and coastal conditions. Since 3000–2000 cal. years BP, the anthropogenic factor (hunting depression of the bird colony) also became significant. During the whole water body lifetime and following peat formation, the diatom community was influenced by groups of factors: global factors (e.g., sea level rise) caused gradual change of local factors, which resulted in smooth shifts in community. In contrast, local factor influence (bird colony rise and fall due to human activity) caused abrupt and transient shifts. We can hypothesize that the relatively stable global environmental conditions in the Late Holocene were an auspicious background to see abrupt changes due to influence of the zoogenic and anthropogenic factors. We believe that further works on the material from other islands will make it possible to form a general picture of changes in the diatom communities in the Holocene and interpret it in connection with climatic changes in the region.
