Desiccation tolerance in peatland desmids: a comparative study of Micrasterias thomasiana and Staurastrum hirsutum (Zygnematophyceae). [PDF]

open access: yesProtoplasma
Desmids are valuable bioindicators in peatland ecosystems due to their sensitivity to environmental changes. In temperate and boreal wetlands, seasonal desiccation of aquatic habitats, which is increasing in frequency and severity due to ongoing climate ...

Cultivation and Photophysiological Characteristics of Desmids in Moderately Saline Aquaculture Wastewater

open access: yesJournal of Phycology, 2021
Although desmids typically inhabit freshwater environments characterized by low amounts of nutrients and low salinity, several desmid species have been recorded in eutrophic waters, indicating their adaptation to elevated pollution and conductivity. This

Fatty acids as chemotaxonomic and ecophysiological traits in green microalgae (desmids, Zygnematophyceae, Streptophyta): A discriminant analysis approach.

open access: yesPhytochemistry, 2019
Desmids (Zygnematophyceae) are a group of poorly studied green microalgae. The aim of the present study was to identify fatty acids (FAs) that could be used as biomarkers in desmids in general, and to determine FAs as traits within different ...
