  • Geographic hierarchical population genetic structuring in British European whitefish (Coregonus lavaretus) and its implications for conservation 

    Crotti, M; Adams, Colin Ean; Etheridge, Elizabeth C.; Bean, Colin W.; Gowans, Andrew R.D.; Knudsen, Rune; Lyle, Alex A.; Maitland, P. S.; Winfield, Ian J.; Elmer, K. R.; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-04)
    The European whitefish <i>Coregonus lavaretus</i> complex represents one of the most diverse radiations within salmonids, with extreme morphological and genetic differentiation across its range. Such variation has led to the assignment of many populations to separate species. In Great Britain, the seven native populations of <i>C. lavaretus</i> (two in Scotland, four in England, one in Wales) were ...

    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 ...
  • Does the Infectious Status of Aphids Influence Their Preference Towards Healthy, Virus-Infected and Endophytically Colonized Plants?
