A novel phylogenetic clade of picocyanobacteria from the Mazurian lakes (Poland) reflects the early ontogeny of glacial lakes.
TLDR
It is hypothesized that Group M originally contained only phycocyanin picocyanobacteria, which seems to have been acquired through horizontal gene transfer as an adaptation to the changing environment early in the ontogeny of these glacial lakes. Expand
Reconstructing euglenoid evolutionary relationships using three genes: nuclear SSU and LSU, and chloroplast SSU rDNA sequences and the description of Euglenaria gen. nov. (Euglenophyta).
TLDR
Combining datasets resolved the relationships among ten genera of photosynthetic euglenoids by using Maximum Likelihood and Bayesian analyses of three genes, nuclear SSU and LSU rDNA, and chloroplast SSU (cpSSU) rDNA. Expand
TAXONOMY OF THE PHACUS OSCILLANS (EUGLENACEAE) AND ITS CLOSE RELATIVES—BALANCING MORPHOLOGICAL AND MOLECULAR FEATURES 1
TLDR
The establishment of epitypes (together with emended diagnoses) for seven species of Phacus Dujard are established by literature studies, verification of morphological diagnostic features (cell size, cell shape), as well as molecular characters (SSU rDNA). Expand
PHYLOGENY AND SYSTEMATICS OF EUGLENA (EUGLENACEAE) SPECIES WITH AXIAL, STELLATE CHLOROPLASTS BASED ON MORPHOLOGICAL AND MOLECULAR DATA—NEW TAXA, EMENDED DIAGNOSES, AND EPITYPIFICATIONS 1
TLDR
Morphological and molecular studies, as well as original literature reexamination, necessitate establishment of five Euglena species with a single axial, stellate chloroplast, allowing distinction of the considered species. Expand
THE SPECIES EUGLENA DESES (EUGLENACEAE) REVISITED: NEW MORPHOLOGICAL AND MOLECULAR DATA 1
TLDR
New diagnostic features for E. deses are defined, namely, periplast ornamentation (the presence of small papillae—discovered for the first time in this species) and the lateral location of the anterior canal opening, from which the flagellum emerges. Expand
Do acid-tolerant picocyanobacteria exist? A study of two strains isolated from humic lakes in Poland
TLDR
The experimental results of this study showed that some picocyanobacteria strains were acid tolerant, achieving higher growth rates and reaching higher maximum numbers in humic, naturally acidic waters rather than in alkaline waters. Expand
TAXONOMIC REVISIONS OF MORPHOLOGICALLY SIMILAR SPECIES FROM TWO EUGLENOID GENERA: EUGLENA (E. GRANULATA AND E. VELATA) AND EUGLENARIA (EU. ANABAENA, EU. CAUDATA, AND EU. CLAVATA) 1
TLDR
The establishment of epitypes (together with the emended diagnoses) for three species of Euglenaria Karnkowska, E. caudata and E. velata are achieved due to literature studies, verification of morphological diagnostic features, as well as molecular characters (SSU rDNA). Expand
A redescription of morphologically similar species from the genus Euglena: E. laciniata, E. sanguinea, E. sociabilis, and E. splendens1
TLDR
The number of species sharing some morphological similarities with E. sanguinea could be reduced from 12, as described in the literature, to four, with established epitypes and updated diagnostic descriptions, through verification of morphological and molecular data for all species similar to E. Sanguinea. Expand
A new photosynthetic euglenoid isolated in Poland: Euglenaria clepsydroides sp. nov. (Euglenea)
In this paper, we describe a new photosynthetic euglenoid species, Euglenaria clepsydroides Zakryś, sp. nov., found in Poland. A large population of this species exists in a few, small, eutrophicExpand
Composition of picocyanobacteria community in the Great Mazurian Lakes: isolation of phycoerythrin-rich and phycocyanin-rich ecotypes from the system--comparison of two methods.
The study showed that the picocyanobacteria community of the Great Mazurian Lakes system (GML) was dominated by phycoerythrin-rich (PE) ecotypes and demonstrated a gradual decrease of the ratioExpand
