    • New combinations of Afrotropical Chironomini (Diptera: Chironomidae) 

      Stur, Elisabeth; Ekrem, Torbjørn (Journal article; Peer reviewed, 2016)
      During our work on the Chironomidae chapter of the forthcoming Manual of Afrotropical Diptera we examined type material of the four Chironomini species Chironomus (Endochironomus) hamatus, Chironomus (E.) pruinosus, ...
    • Nuclear and mitochondrial markers suggest new species boundaries in Alloxysta (Hymenoptera: Cynipoidea: Figitidae) 

      Ferrer-Suay, Mar; Staverløkk, Arnstein; Selfa, Jesús; Pujade-Villar, Juli; Naik, Suresh; Ekrem, Torbjørn (Journal article; Peer reviewed, 2018)
      Due to their small size and smooth body, members of the figitid genus Alloxysta can be notoriously difficult to identify based on morphology alone. Moreover, several species are suspected to contain brachypterous variants ...
    • Phenotypic and genetic variation within the Cricotopus sylvestris species-group (Diptera, Chironomidae), across a Nearctic - Palaearctic gradient 

      Gresens, Susan E.; Stur, Elisabeth; Ekrem, Torbjørn (Journal article; Peer reviewed, 2012)
      Intraspecific variation sometimes obscures species boundaries and makes identification of certain Chironomidae difficult. This is true for many species in the genus Cricotopus. We used DNA barcode data and multivariate ...
    • Phylogenetic analysis of the genus Paratanytarsus (Diptera: Chironomidae) 

      Dahle, Sondre (Master thesis, 2012)
      The non-biting midges (Chironomidae) are among of the most successful insects in freshwater systems and often dominate in abundance and species richness. The genus Paratanytarsus contains species from all biogeographic ...
    • Phylogenetic Evidence of Long Distance Dispersal and Transmission of Piscine Reovirus (PRV) between Farmed and Wild Atlantic Salmon 

      Garseth, Åse Helen; Ekrem, Torbjørn; Biering, Eirik (Journal article; Peer reviewed, 2013)
      The extent and effect of disease interaction and pathogen exchange between wild and farmed fish populations is an ongoing debate and an area of research that is difficult to explore. The objective of this study was to ...
    • Species delimitation in northern European water scavenger beetles of the genus Hydrobius (Coleoptera, Hydrophilidae) 

      Fossen, Erlend Ignacio; Ekrem, Torbjørn; Nilsson, Anders N.; Bergsten, Johannes (Journal article; Peer reviewed, 2016)
      The chiefly Holarctic Hydrobius species complex (Coleoptera, Hydrophilidae) currently consists of H. arcticus Kuwert, 1890, and three morphological variants of H. fuscipes (Linnaeus, 1758): var. fuscipes, var. rottenbergii ...
    • Systematics and evolutionary history of Tanytarsus van der Wulp, 1874 (Diptera: Chironomidae) 

      Lin, Xiaolong (Doctoral theses at NTNU;2017:201, Doctoral thesis, 2017)
      On the evolution and diversity of Tanytarsus non-biting midges / Evolusjon og mangfold hos fjærmygg i slekten Tanytarsus As species are the fundamental unit of biodiversity, accurate species identification and delimitation ...
    • Taxonomy based on science is necessary for global conservation
