Most lotic ecosystems have been heavily modified in recent centuries to serve human needs, for example, by building dams to form reservoirs. However, reservoirs have major impacts on freshwater ecosystem functions and severely affect rheophilic fishes. The main effect is the building of dams which often terminate the migrations and create new lake-type habitats. However, the natural fish...
The article co-authored by Yulia Vystavna and published earlier this year was awarded by the UK Times Higher Education award for International Collaboration of the Year 2022
The book contains the overview and the description of the methods for the monitoring of qualitative and quantitative composition of the fish stock of lakes and reservoirs.
A new study led by Allan T. Souza, from the Institute of Hydrobiology (Biology Centre, CAS) and colleagues from Portugal, was recently published in Science of the Total Environment. The study has revealed the potential effects of climate change on the shore crab (Carcinus maenas) population near the edge of its native range.
An international meeting of experts working on cyanobacteria research is currently taking place in České Budějovice. More than 80 participants of the 22nd Symposium of the International Association of Cyanophyte/Cyanobacteria Research (IAC) participate in a comprehensive discussion on the topics of evolution, taxonomy, ecology, biogeography, and physiology of cyanobacteria and their practical use.
They are always there, dwelling in the water, where they play a key role in food webs, in cycling of nutrients, matter and energy, and water purification. However, as happens with organisms that tend to be inconspicuous and often invisible to the naked eye, society mostly neglects them, and forgets their huge importance in providing support and stability of aquatic ecosystems. What is even more...
Lake Fish Telemetry Group (LFTG), an initiative that brings together research groups involved in lake fish telemetry in Europe is now in its fifth year. The initiative was established in 2018 through the project funded by ALTER-Net (https://alterneteurope.eu) and implemented by the Biology Centre of the Czech Academy of Sciences, Institute of Hydrobiology. Project participants include top...
European Aquatic Animal Tracking Network COST Action (ETN, CA18102) organizes a training school on the topic of how to calculate positions of aquatic animals tracked by acoustic telemetry. The main topics will cover areas of various positioning systems, hierarchical generalized additive models, hidden Markov and step selection models, visualisation of models, and creation and animation of...
The so-called hydropeaking, i.e. discontinuous flow changes in rivers, significantly disrupts fish reproduction. In the current study, scientists from the Institute of Hydrobiology of the Biology Centre of the Czech Academy of Sciences focused on how hydropeaking affects the spawning asp shoal in the Želivka River. The local asp shoal, protected under the Natura 2000, faces unpredictable water...
The international team, which also includes Czech researchers from České Budějovice and Třeboň, received the Newcomb Cleveland Prize from the American Association for the Advancement of Science (AAAS) for the best research article or report published in the scientific journal Science in 2021.
