Autotrophic microorganisms in river outfalls of Lake Elton

Abstract

For the first time, communities of autotrophic microorganisms in outfalls of seven meso and hypersaline rivers located in the Eltonsky Natural Park were studied. As a result, 132 species, variants, and forms from six divisions were found. The specific composition of taxa in every watercourse was noted. A cor relation between species diversity and salinity levels was not revealed.

Cocconeis rouxii Héribaud & Brun a forgotten, but common benthic diatom species from the Massif Central, France

“…Although most of the recent records are from the Holarctic region (Russia mainly), most of its citations are without comprehensive illustrations making these records unverifiable or doubtful (e.g. Antsiferova and Borisova 2009, 91;Chekryzheva 2012, 64;Makarevi 2012, 35;Antsiferova 2013, 110;Makarevich 2013a, 296, 2013b, 206;Petrovska and Stojanovski 2007, 286;Yatsenko-Stepanova, Ignatenko, and Nemtseva 2014, 6;Yatsenko-Stepanova et al 2015a, 50, 2015bAntsiferova 2018, 275;Niyatbekov and Barinova 2008, 305). In none of the mentioned publications could we confirm the presence of the species.…”
