Plastid DNA sequences and oospore characters of some European taxa of Tolypella section Tolypella (Characeae) identify five clusters, including one new cryptic Tolypella taxon from Sardinia, but they do not coincide with current morphological descriptions [PDF]

Frontiers in Plant Science, 2023
In Europe, the genus Tolypella (Characeae) comprises four to eight Tolypella taxa in sections Rothia and Tolypella that have been distinguished by vegetative morphology and gametangial characters such as antheridial size and oospore wall ornamentation ...

Integrative Taxonomic, Ecological and Genotyping Study of Charophyte Populations from the Egyptian Western-Desert Oases and Sinai Peninsula [PDF]

Plants, 2021
Present-day information available on the charophyte macroalgae in Egypt, including their phylogenetic affinities, remains largely incomplete. In this study, nine charophyte populations were collected from different aquatic biotopes across the Egyptian ...

Re-Establishment Techniques and Transplantations of Charophytes to Support Threatened Species [PDF]

Plants, 2021
Re-establishment of submerged macrophytes and especially charophyte vegetation is a common aim in lake management. If revegetation does not happen spontaneously, transplantations may be a suitable option.

Sphaerochara canadensis (Charophyceae): A circumpolar species with a high temperature optimum. [PDF]

J Phycol
Abstract Sphaerochara canadensis, an aquatic macrophyte belonging to the Characeae, is described as a species with a circumpolar distribution and occurs in the polar (to boreal) zonobiomes, suggesting that it is cold‐stenothermic. A recent report of an occurrence in Lake Wolfgangsee, Austria, contradicted this assumption, prompting this study to ...

Untangling climate and water chemistry to predict changes in freshwater macrophyte distributions. [PDF]

Ecol Evol, 2018
Forecasting changes in the distributions of macrophytes is essential to understanding how aquatic ecosystems will respond to climate and environmental changes. A survey of 740 water bodies stratified across 327,000 square kilometers was conducted to document Characeae (green macroalgae) species occurrence and water chemistry data.

Seasonality of water chemistry, carbonate production, and biometric features of two species of Chara in a shallow clear water lake. [PDF]

ScientificWorldJournal, 2014
The objective of this study was to analyze the temporal variability of biometric features and the carbonate production of two charophytes: Chara polyacantha A. Braun and Chara rudis A. Braun against the background of the physical‐chemical properties of water. The investigation was carried out in a small, mid‐forest Lake Jasne (western Poland).

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes. [PDF]

J Eukaryot Microbiol, 2019
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

Water ecological requirements of Characeae taxa in eastern Spain

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2023
Presence of Characeae taxa is limited by the existence of clear and oligotrophic waters. Some other chemical water parameters can also influence the distribution of taxa, which can thus be used as ecological bioindicators.
