Gololobovia gen. nov. – a new genus from Lake Baikal with comments on pore occlusion in monoraphid diatoms

Centric diatom diversity in the lower part of the Southern Bug river (Ukraine): the transitional zone at Mykolaiv city

“…This is a freshwater species, found growing in or near snow and in alpine pools ( Houk et al 2007 ; English and Potapova 2009 ) but was also reported for alkaline and acid waters ( Kulikovskiy et al 2016 ).…”

“…As for general distribution, this taxon has only a few records around the world – Europe (Russia, Ukraine), Asia (Armenia, Russia), Africa (Egypt) ( Kulikovskiy et al 2016 ; Genkal et al 2020 ).…”

“…In Hofmann et al (2018) the taxon is characterised as oligotraphentic and living in dystrophic waters; but this does not seem to correspond to the characteristics of the Ukrainian waters in this area (Mykolaiv regional state administration 2019). Different information for A. nivalis is presented in Kulikovskiy et al (2016), where it is found in alkaline as well as in acidic waters. Ten more taxa found by us in this area are alkalibionts and probably reveal the appropriate conditions for A. nivalis in the investigated water body, if all publications are talking about the same taxon.…”

Two new species of Navicula (Bacillariophyta) from Southeast Asia

“…This investigation continues our description of new species from the genus Navicula Bory from Southeast Asia. With both freshwater and marine representatives, the genus Navicula Bory is the most taxon-rich genus of all diatoms ( Kulikovskiy et al 2016 ). However, the number of species included in this genus has actually been decreasing over the last 20 years mainly because of the description of new genera that include species formerly in in Navicula .…”
