Initial research into the green algae (Chlorophyta) in the ponds of Załęczański Landscape Park [PDF]

open access: yes, 2001
This study contains results of the taxonomic analysis of green algae from the ponds of the Załęczański Landscape Park. Application of the Thumarek’s eutrophy coefficient enabled to mark off oligotrophical and eutrophical ponds on the researched area ...

Effect of polysaccharide capsule of the microalgae Staurastrum iversenii var. americanum on diffusion of charged and uncharged molecules, using EPR technique [PDF]

open access: yes, 2006
The existence of a mucilaginous envelope, sheath or capsule is usual in many desmids, but few data concerning its function are available. Previous studies of the transport function and permeation of molecules through the algae capsules were done using ...

Desmids flora analysis of the peat-bog Lubiec in 1984-1995 [PDF]

open access: yes, 2000
In 1984-1995 the desmid flora was analysed in the Lubiec peat-bog. Of 206 taxa recorded as many as 43.2% were accessory and accidental species, which testifies to a high variability of this desmid community. The Thumark Q green algae factor was applied

Use of eDNA and conventional sampling methods to survey rock pool (gnamma) biodiversity on granite inselbergs

open access: yesAustral Ecology, Volume 49, Issue 8, August 2024.
Environmental DNA sampling coupled with high‐throughput sequencing is increasingly recognized as a useful method for assessing biodiversity with potential applications in terrestrial environments. Rock pools on granite inselbergs support diverse aquatic communities, yet the application of eDNA to document their biodiversity is lacking.

Diversity of freshwater algal assemblages across the United States as revealed by DNA metabarcoding

open access: yesEnvironmental DNA, Volume 6, Issue 1, January–February 2024.
Abstract As freshwater algae respond strongly to environmental conditions, algal communities are routinely used as indicators of aquatic health. Algal bioassessments have historically relied upon microscopy‐based identifications that are typically slow, expensive, taxonomically restricted, and inconsistent across analysts and time.
