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.

Reservoirs as chronicles of socio-economical changes in their catchment

Reservoirs as chronicles of socio-economical changes in their catchment

11. 1. 2018.

In the 20th century, numerous reservoirs were built on the river network in the Czech Republic. Freshwater reservoirs are water bodies of special interest, as they provide various ecosystem services such as the supply of drinking water, agricultural irrigation, industrial and cooling water supplies, power generation, flood control and recreation. During their history, reservoirs have undergone...

The enigmatic SAR202 cluster up close: shedding light on a globally distributed dark ocean lineage involved in sulfur cycling

The enigmatic SAR202 cluster up close: shedding light on a globally distributed dark ocean lineage involved in sulfur cycling

15. 12. 2017.

The dark ocean microbiota represents the unknown majority in the global ocean waters. The SAR202 cluster belonging to the phylum Chloroflexi was the first microbial lineage discovered to specifically inhabit the aphotic realm, where they are abundant and globally distributed. The absence of SAR202 cultured representatives is a significant bottleneck towards understanding their metabolic...

In fall, the reservoir releases a large amount of methane bubbles

In fall, the reservoir releases a large amount of methane bubbles

13. 12. 2017.

Researchers of the Institute of Hydrobiology and SoWa Research Infrastructure are engaged in studying the release of greenhouse gases, especially methane, from reservoirs. The results of their research have recently been published in the prestigious scientific journal Water Resources Research.

From modeling to lake life and back again.

From modeling to lake life and back again.

7. 12. 2017.

The available data on fishery is fragmented and still limited, and thus the CLIMEFISH BC team had to cope with this challenge by processing the available data as well as acquiring more information that could help to develop an optimization on fishery activity in the reservoir.

Collecting plastic bottles to build floating islands

Collecting plastic bottles to build floating islands

29. 11. 2017.

Researchers from the Institute of Hydrobiology BC CAS are building floating islands made of plastic bottles. These islands are used as experimental floating wetlands that will reduce nutrient load and increase biodiversity in reservoirs.

Eat your predator! Small cyprinid fish forage on their natural enemy

Eat your predator! Small cyprinid fish forage on their natural enemy

23. 11. 2017.

Predator - prey relationships are often perceived simply as a situation in which a predator enhances its own fitness while reducing the fitness of its prey. However, this relationship may occasionally become reversed when the prey feeds on the juvenile predator stages.

Fish exploration of reservoirs and lakes: A novel way of mobile echosounding

Fish exploration of reservoirs and lakes: A novel way of mobile echosounding

29. 9. 2017.

The use of echosounders can be perceived as an extremely powerful tool for exploring aquatic ecosystems. Their undeniable advantage is their friendliness to the observed organisms, which are not distracted or damaged. For example, in marine systems, the use of echolsouders is a fundamental approach to studying fish communities and other pelagic organisms. When studying the fish communities of...
