A fluorescence tracer technique reveals novel energy pathways in aquatic systems

A fluorescence tracer technique reveals novel energy pathways in aquatic systems

30. 9. 2019.

Šimek, K. and Sirová, D. 2019: Fluorescently Labeled Bacteria as a Tracer to Reveal Novel Pathways of Organic Carbon Flow in Aquatic Ecosystems. J. Vis. Exp. (151), e59903, doi:10.3791/59903 Elucidating trophic interactions, such as predation and its effects, is a frequent task for many researchers in ecology. The study of microbial communities has many limitations, and...

Bark beetle-induced tree dieback affects water quality

9. 9. 2019.

The bark beetle-induced tree dieback (2004-2008) in a nitrogen saturated, chronically acidified but recovering catchment of Plešné Lake, Czech Republic, resulted in pronounced changes in water chemistry.

Invasion of European catfish

Invasion of European catfish

8. 8. 2019.

European catfish (Silurus glanis) is probably the only one apex predator that has become to be invasive due to human, is there any possible regulation in non-native areas?

Lux in tenebris lucet: Casting light on Asgardarchaeota metabolism in a sunlit microoxic niche

Lux in tenebris lucet: Casting light on Asgardarchaeota metabolism in a sunlit microoxic niche

17. 4. 2019.

Asgardarchaeota, a phylum-level division within the Archaea domain of life, comprises the closest extant relatives of the eukaryotes (discovered to date). Known only from metagenomics-based reconstructions, the members of this clade are found to harbour the most extensive repertoire of eukaryotic specific genes found in prokaryotes, and are expected to shed light on the elusive...

Newcomers play cryptic: The impacts of invasive species are often difficult to predict

Newcomers play cryptic: The impacts of invasive species are often difficult to predict

24. 1. 2019.

New Zealand and other islands have experienced invasions of rats and other species, Europe has seen the arrival of diseases such as the crayfish plague: invasive species can put native animal and plant species on the brink of extinction. They often go undetected for a long time, or their damaging impacts are not immediately clear. This phenomenon – referred to as crypticity – represents a huge...

Niche-directed evolution modulates genome architecture in freshwater Planctomycetes

Niche-directed evolution modulates genome architecture in freshwater Planctomycetes

23. 1. 2019.

Large numbers of bacteria live in freshwater lakes and reservoirs. The microbial universe of these ecosystems is largely unexplored due to our current inability to grow these tiny lifeforms under laboratory conditions. A joint research team from the Department of Aquatic Microbial Ecology (Institute of Hydrobiology, BC, CAS) recently discovered new groups of bacteria thriving in aquatic...

Mediterranean freshwater fish species susceptible to climate change

Mediterranean freshwater fish species susceptible to climate change

14. 1. 2019.

Climate change will strongly affect many European freshwater fish species. This is particularly the case for species in the Mediterranean region, according to the latest findings of an international team of researchers from institutions including the Biology Centre of the Czech Academy of Sciences, Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in Germany, the University of...

New booming boat for fish-friendly research

New booming boat for fish-friendly research

17. 12. 2018.

Our new booming boat type MS Boat S500WT arrived a few days ago. The boat will be used mainly for inshore electrofishing on large standing waters. For this purpose, it is equipped with a powerful engine powered electrofisher achieving an DC and pulse current output of up to 300/600 V.
