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.
Lukáš Vejřík became the winner of the Zdeněk Veselovský Prize for the best student publication in the field of ethology for 2018 for a study focused on the food behavior of catfish. The award is given by the Czech and Slovak ethological society.
Representatives of the phylum Chloroflexi, though reportedly highly abundant in the extensive deep water habitats of both marine (SAR202 up to 30% of total prokaryotes) and freshwater (CL500-11 up to 26% of total prokaryotes), remain uncultivated and uncharacterized. There are few metagenomic studies on marine Chloroflexi representatives, while the pelagic freshwater Chloroflexi community is...
Help us reveal underwater secrets! Institute of Hydrobiology is seeking to appoint an outstanding postdoctoral researcher in the field of aquatic and food web ecology.
Where do fish reside during different parts of the day and seasons? What is the preferred habitat of different species, and how do fish interact in time and space? What are behavioural patterns and differences among economically important, predator fish species such as pike, wels catfish and perch? How do fish react to changes in weather and seasonal conditions, and how are they expected to...
Two basic ecological relationships, herbivory and competition, distinctively influence terrestrial ecosystem characteristics, such as plant cover, species richness and species composition. It is well-known how it works in the terrestrial ecosystems, but what about under water?
Small bacterivorous eukaryotes play a cardinal role in aquatic food webs and their taxonomic classification and ecological traits are currently hot topics in aquatic microbial ecology. Despite increasing interest in their diversity, core questions regarding predator–prey specificity remain largely unanswered, e.g., which heterotrophic nanoflagellates (HNFs) are the main bacterivores in...
Climate change is one of the biggest threats for biodiversity nowadays, affecting many aspects of species life, range of suitable areas of occurrence and ecological interactions. Despite of the severity of the phenomena, the number of studies simulating the effects of climate change on fish populations is still rare. In the last years the scientific community is intensifying the efforts in the...
Thank you very much for collecting empty PET bottles. These bottles, which are otherwise civilization waste, have been considered to be the appropriate material for building floating wetlands, that can greatly enrich the structure of our reservoirs. The bottles you collected have made a significant contribution to the new floating islands on the Lipno reservoir near Černá v Pošumaví .
