    • Cercariae of a Bird Schistosome Follow a Similar Emergence Pattern under Different Subarctic Conditions: First Experimental Study 

      Soldánová, Miroslava; Born-Torrijos, Ana; Kristoffersen, Roar; Knudsen, Rune; Amundsen, Per-Arne; Scholz, Tomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-03)
      The emergence of cercariae from infected mollusks is considered one of the most important adaptive strategies for maintaining the trematode life cycle. Short transmission opportunities of cercariae are often compensated by periodic daily rhythms in the cercarial release. However, there are virtually no data on the cercarial emergence of bird schistosomes from freshwater ecosystems in northern ...

    • 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 ...

    • High parasite diversity in the amphipod Gammarus lacustris in a subarctic lake 

      Shaw, Jenny Carolyn; Henriksen, Eirik Haugstvedt; Knudsen, Rune; Kuhn, Jesper Andreas; Kuris, Armand M.; Lafferty, Kevin D.; Siwertsson, Anna; Soldánová, Miroslava; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-05)
      Amphipods are often key species in aquatic food webs due to their functional roles in the ecosystem and as intermediate hosts for trophically transmitted parasites. Amphipods can also host many parasite species, yet few studies address the entire parasite community of a gammarid population, precluding a more dynamic understanding of the food web. We set out to identify and quantify the parasite ...

    • Molecular analyses reveal high cryptic diversity of trematodes in a sub-Arctic lake 

      Soldánová, Miroslava; Georgieva, Simona; Roháčová, Jana; Knudsen, Rune; Kuhn, Jesper A.; Henriksen, Eirik Haugstvedt; Siwertsson, Anna; Shaw, Jenny C.; Kuris, Armand M.; Amundsen, Per-Arne; Scholz, Tomas; Lafferty, Kevin D.; Kostadinova, Aneta (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-14)
      To identify trematode diversity and life-cycles in the sub-Arctic Lake Takvatn, Norway, we characterised 120 trematode isolates from mollusc first intermediate hosts, metacercariae from second intermediate host fishes and invertebrates, and adults from fish and invertebrate definitive hosts, using molecular techniques. Phylogenies based on nuclear and/or mtDNA revealed high species richness (24 ...

    • Somatic Dimorphism in Cercariae of a Bird Schistosome 

      Soldánová, Miroslava; Kundid, Petra; Scholz, Tomas; Kristoffersen, Roar; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-24)
      Phenotypic polymorphism is a commonly observed phenomenon in nature, but extremely rare in free-living stages of parasites. We describe a unique case of somatic polymorphism in conspecific cercariae of the bird schistosome Trichobilharzia sp. “peregra”, in which two morphs, conspicuously different in their size, were released from a single Radix balthica snail. A detailed morphometric analysis ...

    • Taxa-specific activity loss and mortality patterns in freshwater trematode cercariae under subarctic conditions 

      Born-Torrijos, Ana; Van Beest, Gabrielle S.; Vyhlídalová, Tereza; Knudsen, Rune; Kristoffersen, Roar; Amundsen, Per-Arne; Thieltges, David W.; Soldánová, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-11)
      Cercarial activity and survival are crucial traits for the transmission of trematodes. Temperature is particularly important, as faster depletion of limited cercarial energy reserves occurs at high temperatures. Seasonal climate conditions in high latitude regions may be challenging to complete trematode life cycle during the 6-month ice-free period, but temperature effects on the activity and ...

    • 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 ...
