Establishment of the Lake Fish Telemetry Group, and the upcoming workshop in Ceske Budejovice

26. 10. 2018.

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...

Impact of herbivory and competition on lake ecosystem structure: underwater experimental manipulation

Impact of herbivory and competition on lake ecosystem structure: underwater experimental manipulation

13. 9. 2018.

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?

Which bacterivorous flagellates are major grazers in summer plankton of freshwaters?

Which bacterivorous flagellates are major grazers in summer plankton of freshwaters?

21. 8. 2018.

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...

Projecting the effects of climate change on fish populations

Projecting the effects of climate change on fish populations

15. 6. 2018.

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...

We need more PET bottles

We need more PET bottles

24. 5. 2018.

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 .

Animals in the marketing media deceive us about their survival in the wild

Animals in the marketing media deceive us about their survival in the wild

27. 4. 2018.

The most “charismatic” species have a high status in conservation biology and it is commonly claimed that these species experience a privileged level of attention, often at the expense of other, more ordinary species. However, in a study publishing April 12 in PLOS Biology, an international research team (from France, USA, Czech Republic, Germany, Serbia and Sweden) led by Franck Courchamp,...

How food quality characteristics of bacterial prey modulate growth and community dynamics of bacterivorous flagellates?

How food quality characteristics of bacterial prey modulate growth and community dynamics of bacterivorous flagellates?

8. 2. 2018.

Communities of heterotrophic nanoflagellates (HNF, cell sizes from 2-8 µm) represent a considerable part of plankton associations and are the most numerous predators of bacteria. However, different bacterioplankton species represent different food quality resources for HNF communities, potentially affecting flagellate growth, community dynamics and carbon flow to higher trophic levels. However,...

European catfish drives the freshwater ecosystems

European catfish drives the freshwater ecosystems

17. 1. 2018.

European catfish (Silurus glanis) is an apex predator of the European freshwater ecosystems. Even it is lately on the increase mainly due to human activity, studies dealing with diet behaviour of this species are scarce.

The role of fish in freshwater mussels conservation

The role of fish in freshwater mussels conservation

12. 1. 2018.

Freshwater mussels are among the most threatened faunal groups on Earth. Their life cycle is usually complex, with their larvae using fish for dispersion. Therefore, fishes plays a significant role in the conservation status of mussels worldwide.
