    • Contrasting structural complexity diferentiate hunting strategy in an ambush apex predator 

      Říha, Milan; Gjelland, Karl Øystein; Děd, Vilém; Eloranta, Antti; Rabaneda-Bueno, Ruben; Baktoft, Henrik; Vejřík, Lukáš; Vejříková, Ivana; Drastik, Vladislav; Šmejkal, Marek; Holubová, Michaela; Jůza, Tomáš; Rosten, Carolyn; Sajdlová, Zuzana; Økland, Finn; Peterka, Jiří (Peer reviewed; Journal article, 2021)
      Structural complexity is known to influence prey behaviour, mortality and population structure, but the effects on predators have received less attention. We tested whether contrasting structural complexity in two newly ...

    • Effects of water level regulation in alpine hydropower reservoirs: an ecosystem perspective with a special emphasis on fish 

      Hirsch, Philipp E.; Eloranta, Antti; Amundsen, Per-Arne; Brabrand, Åge; Charmasson, Julie; Helland, Ingeborg Palm; Power, Michael John; Sanchez-Hernandez, Javier; Sandlund, Odd Terje; Sauterleute, Julian Friedrich; Skoglund, Sigrid Østrem; Ugedal, Ola; Yang, Hong (Journal article; Peer reviewed, 2017)
      Sustainable development of hydropower demands a holistic view of potential impacts of water level regulation (WLR) on reservoir ecosystems. Most environmental studies of hydropower have focused on rivers, whereas environmental ...

    • European catfsh (Silurus glanis) as a freshwater apex predator drives ecosystem via its diet adaptability 

      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. ...

    • Hydropower impacts on reservoir fish populations are modified by environmental variation 

      Eloranta, Antti; Finstad, Anders Gravbrøt; Helland, Ingeborg Palm; Ugedal, Ola; Power, Michael (Journal article; Peer reviewed, 2018)
      Global transition towards renewable energy production has increased the demand for newand more flexible hydropower operations. Beforemanagement and stakeholders can make informed choices on potential mitigations, it is ...

    • Impacts of piscicide-induced fish removal on resource use and trophic diversity of lake invertebrates 

      Eloranta, Antti; Kjærstad, Gaute; Power, Michael; Lakka, Hanna-Kaisa; Arnekleiv, Jo Vegar; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2022)
      Chemical eradication of non-native species has become a widely used method to mitigate the potential negative im- pacts of altered competitive or predatory dynamics on biodiversity and natural ecosystem processes. However, ...

    • Introduced European smelt (Osmerus eperlanus) affects food web and fish community in a large Norwegian lake 

      Eloranta, Antti; Johnsen, Stein Ivar; Power, Michael; Bærum, Kim Magnus; Sandlund, Odd Terje; Finstad, Anders Gravbrøt; Rognerud, Sigurd; Museth, Jon (Journal article; Peer reviewed, 2018)
      Invasive and introduced fishes can affect recipient ecosystems and native species via altered competitive and predatory interactions, potentially leading to top-down and bottom-up cascading impacts. Here, we describe a ...

    • Macrophytes shape trophic niche variation among generalist fishes 

      Vejříková, Ivana; Eloranta, Antti; Vejřík, Lukáš; Šmejkal, Marek; Cech, Martin; Sajdlová, Zuzana; Frouzova, Jaroslava; Kiljunen, Mikko; Peterka, Jiří (Journal article; Peer reviewed, 2017)
      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 ...

    • Trophic ecology of piscivorous Arctic charr (Salvelinus alpinus (L.)) in subarctic lakes with contrasting food-web structures 

      Kahilainen, Kimmo Kalevi; Thomas, Stephen; Harrod, Chris; Hayden, Brian; Eloranta, Antti (Journal article; Peer reviewed, 2018)
      The trophic ecology of piscivorous Arctic charr (Salvelinus alpinus (L.); charr) in the food webs of large subarctic lakes is not well understood. We assessed charr diets, parasites, growth, maturity, and stable isotope ...
