View article: 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
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 Open
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 o…

Increases in temperature and freshwater inputs will shift grazing patterns of a coastal mesograzer on foundation species Open
Foundation species, and the roles that they play in structuring ecosystems, are threatened by global change. For example, charophytes are a refuge for zooplankton and stabilize sediments, but they are also a food source for various animal …

Chara zeylanica J.G.Klein ex Willd. (Charophyceae, Charales, Characeae): First European Record from the Island of Sardinia, Italy Open
The first record of a species belonging to the genus Chara L. subgenus Chara R.D.Wood section Grovesia R.D.Wood subsect. Willdenowia R.D.Wood from Europe is presented here, thus challenging the interpretation of its distribution pattern as…

Applications of environmental DNA methods for charophyte biodiversity Open
The use of environmental DNA (eDNA) for qualitative species inventories offers great potential as a cost-effective tool for species identification. This requires that the target species release DNA, reference information is available and d…

Development of specific markers for the detection of Tolypella canadensis eDNA in water samples Open
Assessing the biodiversity of an ecosystem plays a major role in ecosystem management. However, proper determination on species-level is often tricky when morphological features are scarce and especially rare species require huge sampling …

Temperature-Salinity dependent grazing rates of Gammarus tigrinus on charophytes Open
These data sets include raw data on laboratory observed grazing rates of Gammarus tigrinus on Chara aspera (c_asp) and Chara tomentosa (c_tom) along a full factorial temperature and salinity gradient. Additionally, macrophyte biomass devel…

Charophytes in warm springs on Svalbard (Spitsbergen): DNA barcoding identifies <i>Chara aspera</i> and <i>Chara canescens</i> with unusual morphological traits Open
The Troll springs are warm springs on Svalbard (Spitsbergen). Charophytes were collected in the years 1910, 1912, 1958, 1992/1993, and 2018. However, since the Chara samples showed unusual morphological traits, there were doubts with respe…

The occurrence of sexual<i>Chara canescens</i>(Charales, Charophyceae) in Sardinia (Italy) Open
Chara canescens Loisel. is the only haplostichous charophyte species in Europe. Populations with parthenogenetically reproducing females have been described from several European locations. In contrast, populations with female and male ind…

Species differentiation in the genus <i>Chara</i> (Charophyceae): considerable phenotypic plasticity occurs within homogenous genetic groups Open
Charophytes are benthic algae with a complex morphology and high phenotypic plasticity. This has led to ambiguities in species delineation. However, until now genetic studies on Chara have been based on samples collected from a restricted …
