The freshwater red alga Batrachospermum gelatinosum inhabits streams of Europe and North America and has been collected frequently on both continents. A study of this species in North America showed evidence of a glacial refugium in the southeastern

Species level taxonomy and phylogeographical distribution patterns in the freshwater rhodophyte Sirodotia are resolved through phylogenetic inferences based on rbcL and cox2–3 sequence data. Previous studies focused on the taxonomy of specific Siro

Of the total number of freshwater red algae (ca. 180 taxa), one third are found in Europe (ca. 60 taxa). Over one third (24 taxa) of European taxa have been found at only one single location or at very few locations. The majority of taxa live in runn

As wholesale biodiversity assessment is often impractical, the use of surrogates that reflect the assemblage structure and diversity of other taxa has attracted increased attention. We sampled 47 boreal streams for diatoms and macroalgae and examined

The paper gives new data on the occurrence of Batrachospermum atrum (Hudson) Harvey, a freshwater Rhodophyta species rare in Poland. It was found growing on stony bottom in a small stream in northwestern Poland; at this site it was associated mainly

New records for freshwater red algae are given: Lemanea borealis, new for Europe; Bangia atropurpurea, Batrachospermum helminthosum, B. skujae and Lemanea condensata, new for Finland; and new records for some other interesting and rather rare taxa su

Biological and chemical data were processed to estimate trophic stage and degree of pollution in several streams and rivers in southern Poland. The majority were eutrophic and some of them heavily polluted; only a few were oligo-mesotrophic. The diff

Many methods for using diatoms for routine monitoring of water quality have been developed in Europe and, in some countries, these are being used to enforce environmental legislation. In order to facilitate their wider use, particularly with respect

The freshwater red algal genus Batrachospermum has been shown to be paraphyletic since the first molecular studies of the Batrachospermales. Previous research, along with this study, provides strong support for the clade Batrachospermum section Helmi
