      Vejřík, Lukáš; Vejříková, Ivana; Blabolil, Petr; Eloranta, Antti; Kočvara, Luboš; Peterka, Jiří; Sajdlová, Zuzana; The Chung, Son Hoang; Šmejkal, Marek; Kiljunen, Mikko; Cech, Martin (Journal article; Peer reviewed, 2017)
      Apex predators play a key role in ecosystem stability across environments but their numbers in general are decreasing. By contrast, European catfish (Silurus glanis), the European freshwater apex predator, is on the increase. ...

      Generalist species commonly have a fundamental role in ecosystems as they can integrate spatially distinct habitats and food-web compartments, as well as control the composition, abundance and behavior of organisms at ...
    • Stable isotopes and gut contents indicate differential resource use by coexisting asp (Leuciscus aspius) and pikeperch (Sander lucioperca) 

      Vašek, Mojmír; Eloranta, Antti; Vejříková, Ivana; Blabolil, Petr; Říha, Milan; Jůza, Tomáš; Šmejkal, Marek; Matěna, Josef; Kubečka, Jan; Peterka, Jiří (Journal article; Peer reviewed, 2018)
      Differential use of habitat and prey resources is an important mechanism that may allow coexistence of sympatric species. Unlike interactions between smaller cyprinid and percid fishes, the resource use by coexisting ...
