This chapter is a critical review about the ecological niche dimensions of charophytes. It focuses on recent findings, revising the often-cited view of charophytes being clearwater-indicators in general. By tackling the mechanisms responsible for installation of stands, maintaining them as well as physiologigal features allowing growth under extrem...

The analysis of biological and ecological traits has a long history in evolutionary and ecological research. However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait info...

This study contributes to a better understanding of geogenic reef distribution in the southern Baltic Sea and highlights the implications of survey-related factors on automated boulder classification when utilizing data from multiple surveys. The distribution of hard grounds and reefs is needed as a baseline for geological and biological studies, b...

Mining effluents are colonized by algae, moss, fungi and higher plants. Many of these can extract and hyperaccumulate metals. This process is known as biological polishing. Algae growing in mine effluents can sequester metals through adsorption onto cell walls and by absorption. Charophytes are a specialized group of algae that grow in temperate fr...

The immediate effect of zinc (Zn) and hydrogen peroxide (H2O2) in Chara braunii was analyzed in short‐time exposure experiments. The exposure concentrations were 12.3, 18.4, and 24.5 μmol L−1 H2O2, 12, 60, and 120 mg L−1 Zn, and 12.3 μmol L−1 H2O2 + 12 mg L−1 Zn, 12.3 μmol L−1 H2O2 + 60 mg L−1 Zn, and 18.4 μmol L−1 H2O2 + 12 mg L−1 Zn. The stress r...

Over the past few decades water bodies have been heavily contaminated by the heavy metals thus charophytes communities tended to disappear from their own habitat niches. In this experiment we hypothesized that elevating Cu concentrations and increasing exposure time deviates the biochemical responses of Chara braunii . For evaluating this hypothesi...

Mine drainage water from the Schlenze stream, Mansfeld Region, Central Germany, which have shown an increase in heavy metal concentrations of Cd²⁺, Cu²⁺, Pb²⁺, and Zn²⁺, was used to investigate the bioremediation potential of charophytes. The removal of heavy metals by Chara subspinosa from the water was tested in single- and multi-metal additions....

We compared the validity of two low cost camera systems to analyze the fi ltration activity of Diplodon chilensis (Gray, 1828), the most common freshwater bivalve in southern Chile, by using time lapse photography. One camera system (Nikon D300) was connected with an external fl ash, whereas the other system (GoPro Hero 3+) contained a permanent vi...

Abstract Encrustation and element content (Ca, Fe, K, Mg and P) of charophytes was studied along plant thalli to investigate the dependency of thallus age and site-specificity. Charophytes were collected from five sampling sites (Angersdorfer Teiche, Asche, Bruchwiesen, Krüselinsee and Lützlower See) which were distinct with respect to water chemis...

Encrustation and element content of six charophyte species from two hard‐water lakes were investigated monthly for a period of one year. Seasonal patterns were analyzed for the interaction of water chemistry. Encrustation followed a seasonal pattern for Chara contraria, C. subspinosa and Nitellopsis obtusa in Lake Krüselin and for C. globularis and...

Comparison of encrustation and analysis of element contents across species growing in freshwater (FW) and brackish water (BW) have never been done. Proportion of carbonate and element composition for Ca, K, Mg, Na, and P of plant DW were investigated in four charophyte species from ten freshwater and six brackish water sites in northern Europe.
