    • Cercarial behaviour alters the consumer functional response of three-spined sticklebacks 

      Born-Torrijos, Ana; Paterson, Rachel; van Beest, Gabrielle; Vyhlídalová, Tereza; Henriksen, Eirik Haugstvedt; Knudsen, Rune; Kristoffersen, Roar; Amundsen, Per-Arne; Soldánová, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-22)
      <ol> <li>Free-living parasite life stages may contribute substantially to ecosystem biomass and thus represent a significant source of energy flow when consumed by non-host organisms. However, ambient temperature and the predator's own infection status may modulate consumption rates towards parasite prey.</li> <li>We investigated the combined effects of temperature and predator infection status ...

    • Global analysis of seasonal changes in trematode infection levels reveals weak and variable link to temperature 

      Paterson, Rachel; Poulin, Robert; Selbach, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-26)
      Seasonal changes in environmental conditions drive phenology, i.e., the annual timing of biological events ranging from the individual to the ecosystem. Phenological patterns and successional abundance cycles have been particularly well studied in temperate freshwater systems, showing strong and predictable synchrony with seasonal changes. However, seasonal successional changes in the abundance ...

    • Temperature does not influence functional response of amphipods consuming different trematode prey 

      Born-Torrijos, Ana; Paterson, Rachel; van Beest, Gabrielle; Schwelm, Jessica; Vyhlídalová, Tereza; Henriksen, Eirik Haugstvedt; Knudsen, Rune; Kristoffersen, Roar; Amundsen, Per-Arne; Soldánová, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-26)
      Direct consumption on free-living cercariae stages of trematodes by non-host organisms interferes with trematode transmission and leads to reduced infections in the next suitable hosts. Consumer functional responses provide a useful tool to examine relationships between consumption rates and ecologically relevant prey densities, whilst also accounting for abiotic factors that likely influence ...

    • Temporal stability of polymorphic Arctic charr parasite communities reflects sustained divergent trophic niches 

      Rochat, Eloïse Coralie; Paterson, Rachel; Costa, Isabel Blasco; Power, Michael; Adams, Colin E.; Greer, Ron; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-05)
      Polymorphic Arctic charr Salvelinus alpinus populations frequently display distinct differences in habitat use, diet, and parasite communities. Changes to the relative species densities and composition of the wider fish community have the potential to alter the habitat niche of sympatric Arctic charr populations. This study evaluated the temporal stability of the parasite community, diet, and stable ...
