The diversity of Cyanoprokaryota from freshwater and terrestrial habitats in the Eurasian Arctic and Hypoarctic

Dynamics of nutrient and phytoplankton in Epe Lagoon, Nigeria: possible causes and consequences of reoccurring cyanobacterial blooms

“…For instance, potentially toxic cyanobacteria Snowella fennica, Microcystis aeruginosa, Planktothrix agardhii and Anabaena circinalis were reported in Paso de las Piedras reservoir, Buenos Aires, Argentina (Fernández et al 2015). Furthermore, blooms of Aphanizomenon, Dolichospermum, Nodularia and Phormidium have been documented in ecological studies of the Eurasian Arctic and Hypoarctic large river estuaries (Davydov and Patova 2017). In reference to the alert framework for cyanobacteria in coastal waters (Bartram et al 1999), alert level 1 (≥ 2000 cells/ml) was exceeded at Epe lagoon (Ikosi).…”

“…The frequency of eutrophic events has increased over the last several decades in many coastal ecosystems where blooms of phytoplankton are particularly affected by riverine discharge (Paerl et al 2018). For instance, bloom incidences have been reported in Chesapeake Bay (Officer et al 1984), the northern Adriatic Sea (Justic et al 1987), the Baltic Sea (Andersson and Rydberg 1988), Neuse River Estuary (Paerl 2006), Pearl River Estuary , Kopački Rit floodplain (Mihaljevic and Stevic 2011), South African inland waters (Matthews and Bernard 2015), Wadden Sea (Vogt et al 2017), Eurasian Arctic and Hypoarctic large River Estuaries (Davydov and Patova 2017) and Lake Taihu, China (Li and Qin 2019).…”

Introduction: Recent developments in cyanobacterial research with special reference to aquatic habitats, molecular ecology and phylogenetic taxonomy

“…The thematic clusters of contributions in this special section (Supplementary Table 1) comprised the following: (i) problems and developments of the polyphasic evaluation of cyanobacterial biodiversity on the generic and suprageneric levels (Komárek, 2017;Mareš, 2017), and on the infrageneric level (Kurmayer et al, 2017;Rigonato et al, 2017), based on phylogenetic taxonomy; (ii) implementation of the results of modern taxonomic surveys into practical applications such as floristic and environmental research (Davydov & Patova, 2017;Komárek, 2017); (iii) molecular and morphological diversity and adaptation of taxa and/or OTUs to special environments and niches assessed by next-generation sequencing Ruber et al, 2017;Vogt et al, 2017); and (iv) occurrence of specific morphospecies and communities linked to and regulated by specific environmental characteristics in biocalcified lowland streams (Pentecost, 2017), alpine streams (Kurmayer et al, 2017), stratified freshwater lakes (Ruber et al, 2017), and marine tidal flats . The main merits and the taxonomic and biogeographic scope of the individual contributions are summarized in Online Supplemental Table 1.…”

“…Being open access, they provide an improved tool for the environmentalists and other specialists seeking the current taxonomic updates, species lists, and catalogues from different regions and habitats. The contribution by Davydov & Patova (2017) has listed over 600 cyanobacterial species from about 1500 locations in the Eurasian Arctic and Hypoarctic in the CYANOpro database ( http://kpabg.ru/cyanopro/) making it an excellent resource for further research in this area. Another way of maintaining the awareness of the recent taxonomic changes is regular publication of reviews that explain the current criteria for definition of taxa and summarize the most important changes.…”

Checklist of cyanobacteria from the European polar desert zone

“…The functional role of cyanoprokaryotes in polar biotopes is important, because they are a significant producer of organic matter. Indeed, the cyanobacterial microflora of the polar desert zone is poorly known (dAvydov & PAtovA, 2018). The data on their diversity are still incomplete, due to the remoteness of the region.…”
