Molecular and morphological delimitation of species in Strombomonas (Euglenaceae) including a protocol for DNA isolation utilising a chelating resin

TAXON, Volume 72, Issue 4, Page 733-750, August 2023., 2023
Abstract Although Strombomonas verrucosa has been the type of the genus name for almost 100 years, its lack of clear diagnostic traits has rendered morphological distinction from its congeners almost impossible. As such, a study was conducted combining previously unused morphological data (chloroplast characters) with molecular data (sequences of ...

Comparative study of algal community in African sharptooth catfish (Clarias gariepinus, Burchell 1822) and Nile tilapia (Oreochromis niloticus, Linnaeus 1758) farming ponds

Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 149-164, April 2023., 2023
In the fish farming station, algae specific richness varies according to the water collection point (rearing pond, evacuation canal and decantation pond). Algae contribute differentially to fish diets: biomass is mostly used by Nile Tilapia (herbivorous) than African catfish (omnivorous).

18S rDNA sequence–structure phylogeny of the Euglenophyceae (Euglenozoa, Euglenida)

Journal of Eukaryotic Microbiology, Volume 70, Issue 2, March/April 2023., 2023
Abstract The phylogeny of Euglenophyceae (Euglenozoa, Euglenida) has been discussed for decades with new genera being described in the last few years. In this study, we reconstruct a phylogeny using 18S rDNA sequence and structural data simultaneously. Using homology modeling, individual secondary structures were predicted.

Food niches of planktonic rotifers: Diversification and implications

Limnology and Oceanography, Volume 67, Issue 10, Page 2218-2251, October 2022., 2022
Abstract The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations and experiments. Also considered are methodological approaches, rotifer feeding mechanisms, and the availability in natural waters of less well‐known food items (detritus, picoplankton, protozoans).

Quantifying seasonal succession of phytoplankton trait‐environment associations in human‐altered landscapes

Limnology and Oceanography, Volume 66, Issue 4, Page 1409-1423, April 2021., 2021
Abstract Integration of species traits in direct gradient analysis generates insights into how communities are assembled and may respond to environmental changes. We investigated phytoplankton trait‐environment relationships for over 300 taxa during the open‐water season across 75 north‐temperate lakes and reservoirs in Alberta, Canada.

Eutrophication management in a Great Lakes wetland: examination of the existence of alternative ecological states

Ecosphere, Volume 12, Issue 2, February 2021., 2021
Abstract The degradation and loss of ecologically important wetlands has been a topical issue in the Great Lakes region, where 60–80% of the coastal wetlands have been lost since the 1800s. The present modeling study aims to guide the restoration efforts in Cootes Paradise marsh, one of the most degraded shallow wetlands in Southern Ontario.

Phagotrophic algae in a wastewater stabilization pond

International Journal of Aquatic Biology, 2018
In the course of evolution, phagotrophic euglenoids developed before the phototrophic species. Most phagotrophic euglenoids have a robust feeding apparatus.

An in situ test to explore the responses of Scenedesmus acutus and Lepocinclis acus as indicators of the changes in water quality in lowland streams

Ecotoxicology and Environmental Safety, 2012
This bioassay was designed with the aim of exploring the responses of two wild planktonic microalgae exposed in situ (72 h) as indicators of the changes in water quality. Monocultures of both strains within dialysis membrane bags were placed at two sites in a small lowland stream. Site 1 is located at a suburban area with low horticultural activity and

Contemporary integrative taxonomy for sexually deprived protists: A case study of Trachelomonas (Euglenaceae) from western Ukraine

TAXON, Volume 69, Issue 1, Page 28-42, February 2020., 2020
Abstract As many other protist groups, euglenophytes are prone to false identification based solely on morphology because of a limited amount of morphological features and cryptic speciation. One of the supposedly completely asexual groups within the freshwater phototrophic representatives of euglenophytes is Trachelomonas, capable of forming an ...

Distribution and Diversity of Euglenoid flagellates in Safilguda Lake, Hyderabad (India) [PDF]

EPJ Web of Conferences
The Euglenoid flagellates found in Safilguda lake are the focus of this research article. To accomplish this, physico-chemical factors were examined for the water samples obtained from three sampling stations of the lake from May 2022 to April 2023 ...
