The Occurrence of Diatoms from Genus Kobayasiella in Southern Poland

Noga Teresa, Poradowska Anita

Journal of Ecological Engineering

2022

Vol. 23, nr 4

197--200

The Kobayasiella genus develops mostly in oligoor dystrophic freshwaters with low to medium electrolyte content. The studies carried out from 2008 to 2016 in southern Poland showed the presence of four Kobayasiella species. These species usually occurred individually in peatland areas or in the upper sections of small rivers and streams. The species presented in the study were most frequently found in oligotrophic peatbogs, characterized by acidic or very acidic waters with low or medium conductivity values.

New localities of rare species Kobayasiella okadae (Skvortzov) Lange-Bert. and K. tintinnus Buczkó, Wojtal & Jahn in Europe : morphological and ecological characteristics

Oceanological and Hydrobiological Studies

The aim of the present work conducted in the area of Międzyrzeki Strict Nature Reserve in the Roztocze National Park was to show new sites of rare and species new to Poland from the Kobayasiella genus (K. okadae (Skvortzov) Lange-Bert., K. tintinnus Buczkó, Wojtal & Jahn) with regard to morphological and ecological characteristics. Chemical parameters show that investigated habitats are poor and oligotrophic with a low content of chlorides, sulfates and nitrates. K. okadae, K. subtilissima (Cleve) Lange-Bert. and K. tintinnus were found in the studied area. The authors suggest the use of synonym Navicula hoeflerii Cholnoky for the Kobayasiella okadae. LM and SEM images were used in the analysis of the material.
