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,...
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 (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.
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.
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 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...
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.
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.
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.
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.
