    • Beyond ecological opportunity: prey diversity rather than abundance shapes predator niche variation 

      Sanchez-Hernandez, Javier; Finstad, Anders Gravbrøt; Arnekleiv, Jo Vegar; Kjærstad, Gaute; Amundsen, Per-Arne (Peer reviewed; Journal article, 2021)
      Ecological opportunity (i.e. the diversity of available resources) has a pivotal role in shaping niche variation and trophic specialisation of animals. However, ecological opportunity can be described with regard to both ...

    • Community structure affects trophic ontogeny in a predatory fish 

      Sanchez-Hernandez, Javier; Eloranta, Antti; Finstad, Anders Gravbrøt; Amundsen, Per-Arne (Journal article; Peer reviewed, 2017)
      While most studies have focused on the timing and nature of ontogenetic niche shifts, information is scarce about the effects of community structure on trophic ontogeny of top predators. We investigated how community ...

    • Drivers of diet patterns in a globally distributed freshwater fish species 

      Javier, Sánchez-Hernández; Finstad, Anders Gravbrøt; Arnekleiv, Jo Vegar; Kjærstad, Gaute; Amundsen, Per-Arne (Journal article; Peer reviewed, 2018)
      We analysed data of a globally distributed model organism (brown trout) in an attempt to understand relationships among biogeography, prey communities and climate on diet composition at regional spatial scales (Scandinavia), ...

    • Integrating dispersal along freshwater ecosystems into species distribution models 

      Perrin, Sam Wenaas; Englund, Göran; Blumentrath, Stefan; O'Hara, Robert Brian; Amundsen, Per-Arne; Finstad, Anders Gravbrøt (Journal article; Peer reviewed, 2020)
      Aim: Our ability to model species distributions and abundances is a valuable ecological tool in predicting future distributions of species. Effectively incorporating connectivity into these predictions is crucial; however, ...
