The global distribution, abundance, and diversity of microscopic freshwater algae demonstrate an ability to overcome significant barriers such as dry land and oceans by exploiting a range of biotic and abiotic colonization vectors. If these vectors are considered unlimited and colonization occurs in proportion to population size, then globally ubiquitous distributions are predicted to arise. Th...

Coralline red algae are significant components of sea bottom and up to now considered as exclusively marine species. Here we present the first coralline alga from a freshwater environment, found in the Cetina River (Adriatic Sea watershed). The alga is fully adapted to freshwater, as attested by reproductive structures, sporelings, and an inability to survive brackish conditions. Morphological ...

POŠTULKOVÁ EVA, KOPP RADOVAN. 2016. Guanicid and PHMG Toxicity Tests on Aquatic Organisms. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 129–134. The emergence and development of new algicidal products is caused by the ever increasing popularity of garden ponds as well as the use of these products in the fi sheries sector, especially for disposal of cyanobacteri...

Since increasing the NO3 and NH4 make eutrophication in waterbodies, microalgae tolerance tohigh concentrations of NO3 and NH4 and their growth in these levels indicate the bioremediationpotential of nitrogen-rich wastewaters and produce efficient algal biomass in freshwaterenvironments. To evaluate the tolerance of green algae, Scenedesmus quadricauda to different NO3and NH...

The use of biosorbents for heavy metal removal has revealed enormous potential of algae for biosorption. The dried biomass of Spirogyra hyalina was used as biosorbent for removal of cadmium (Cd), mercury (Hg), lead (Pb), arsenic (As) and cobalt (Co) from aqueous solutions atdifferent initial concentrations of the heavy metals and contact time of the biomass. The results showed that highest amou...

We asked whether species richness or species identity contributed more to ecosystem function in a trait-based functional group, burrowing, filter-feeding bivalves (freshwater mussels: Unionidae), and whether their importance changed with environmental context and species composition. We conducted a manipulative experiment in a small river examining the effects of mussel assemblages varying from...
