Genetic variability of Euglena agilis (Euglenophyceae)

Acta Societatis Botanicorum Poloniae, 2011
The results of the internal transcribed spacer (ITS2) of extrachromosomal rDNA and the chloroplast SSU rDNA sequence analysis presented here confirmed elevated genetic polymorphism revealed earlier by RFLP and RAPD for seven clones of the cosmopolitan ...

Colour range of euglenoid ( Euglenophyceae ) blooms

Plant and Fungal Systematics
The presence of autotrophs, heterotrophs and mixotrophs among euglenoid taxa, multiple means of nutrition, and high tolerance to a wide range of thermal living conditions contribute to their colonization of various types of water bodies in different ...

Taxon-rich multigene phylogeny of photosynthetic euglenoids (Euglenophyceae) [PDF]

Frontiers in Ecology and Evolution, 2015
To establish taxonomy and understand phylogenetic relationships among strains and species of the photosynthetic euglenoids, we performed phylogenetic analyses based on a four gene sequence dataset (nr SSU and LSU rDNA, and pt SSU and LSU rDNA) from 343 ...

Phylogeny and classification of Euglenids: a brief review [PDF]

Frontiers in Ecology and Evolution, 2016
Euglenophyceae (phototrophic euglenids) are an important lineage within the Euglenida, Euglenozoa. Most of the approximately 3,000 described species are free-living, phototrophic, unicellular flagellates with one to several plastids of secondary origin ...

Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River. [PDF]

Ecol Evol
This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

Determinants of Cyanobacteria and Algae Diversity in Natural Freshwater Micro-Ecosystems. [PDF]

Environ Microbiol
The Shannon Index, turbidity and luminosity negatively affected the LCBD, species with intermediate frequency of occurrence affected the LCBD, cyanobacteria and green algae are the groups that contribute most to the SCBD, as well as species with accessory frequency.

Ultrastructure of Olkasia polycarbonata (Euglenozoa, Euglenida) demonstrates cytoskeletal innovations associated with the feeding and flagellar apparatuses. [PDF]

J Eukaryot Microbiol
Abstract Euglenids are flagellates with diverse modes of nutrition, including the photosynthetic Euglenophyceae, which acquired plastids via secondary endosymbiosis with green algae, and a diverse assemblage of predators of bacteria and other microeukaryotes.

Broad-range necrophytophagy in the flagellate Orciraptor agilis (Viridiraptoridae, Cercozoa) and the underappreciated role of scavenging among protists. [PDF]

J Eukaryot Microbiol
Abstract Protists show diverse lifestyles and fulfill important ecological roles as primary producers, predators, symbionts, and parasites. The degradation of dead microbial biomass, instead, is mainly attributed to bacteria and fungi, while necrophagy by protists remains poorly recognized.
