    • Conspecific migration and environmental setting determine parasite infracommunities of non-migratory individual fish 

      Rochat, Eloïse; Brodersen, Jakob; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-24)
      Parasite infracommunities tend to be stochastic in nature, although environmental characteristics such as the type of water source in streams and host traits can have an effect on the biotic assemblages and by extension the parasite fauna. We examined the effect of water source and the rate of adult fish migration on the metazoan parasite infracommunities of conspecific juvenile brown trout, Salmo ...

    • Mining various genomic resources to resolve old alpha-taxonomy questions: A test of the species hypothesis of the Proteocephalus longicollis species complex (Cestoda: Platyhelminthes) from salmonid fishes 

      Brabec, Jan; Rochat, Eloïse Coralie; Knudsen, Rune; Scholz, Tomas; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-24)
      High-throughput sequencing strategies became commonly employed to study non-model parasites, but the corresponding genomes and transcriptomes were seldom mined following the original publication. Similar to the data generated with genome skimming techniques based on shallow-depth shotgun gen omes, various genomic and transcriptomic resources can be screened for useful molecular phylogenetic markers ...

    • Next-generation cophylogeny: unravelling eco-evolutionary processes 

      Costa, Isabel Blasco; Hayward, Alexander; Poulin, Robert; Balbuena, Juan A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-07)
      A fundamental question in evolutionary biology is how microevolutionary processes translate into species diversification. Cophylogeny provides an appropriate framework to address this for symbiotic associations, but historically has been primarily limited to unveiling patterns. We argue that it is essential to integrate advances from ecology and evolutionary biology into cophylogeny, to gain ...

    • Phylogeography and cryptic species structure of a locally adapted parasite in New Zealand 

      Feijen, Frida; Zajac, Natalia; Vorburger, Christoph; Costa, Isabel Blasco; Jokela, Jukka (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-21)
      The phylogeographic patterns of many taxa on New Zealand's South Island are characterized by disjunct distributions that have been attributed to Pleistocene climatic cycles and the formation of the Southern Alps. Pleistocene glaciation has been implicated in shaping the contemporary genetic differentiation between populations of the aquatic snail Potamopyrgus antipodarum. We investigated whether ...

    • Sensitivity of bipartite network analyses to incomplete sampling and taxonomic uncertainty 

      Llopis-Belenguer, Cristina; Balbuena, Juan Antonio; Costa, Isabel Blasco; Karvonen, Anssi; Sarabeev, Volodimir; Jokela, Jukka (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-23)
      Bipartite network analysis is a powerful tool to study the processes structuring interactions in ecological communities. In applying the method, it is assumed that the sampled interactions provide an accurate representation of the actual community. However, acquiring a representative sample may be difficult as not all species are equally abundant or easily identifiable. Two potential sampling ...

    • 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 ...
