      Vitamin B1 (thiamin) deficiency is an issue periodically affecting a wide range of taxa worldwide. In aquatic pelagic systems, thiamin is mainly produced by bacteria and phytoplankton and is transferred to fish and birds ...
    • DNA metabarcoding adds valuable information for management of biodiversity in roadside stormwater ponds 

      Sun, Zhenhua; Majaneva, Markus; Sokolova, Ekaterina; Rauch, Sébastien; Meland, Sondre; Ekrem, Torbjørn (Journal article; Peer reviewed, 2019)
      Stormwater ponds are used to compensate for the adverse effects that road runoff might have on the natural environment. Depending on their design and placement, stormwater ponds can act as both refugia and traps for local ...
    • DNA-metastrekkoding til undersøkelser av invertebrater i ferskvann 

      Ekrem, Torbjørn; Majaneva, Markus (NTNU Vitenskapsmuseet naturhistorisk notat;, Research report, 2019)
      DNA-metastrekkoding (metabarcoding) er en teknikk der en ved hjelp av korte DNA-sekvenser kan identifisere artene i en miljø- eller bulkprøve (usortert samleprøve). Metoden har potensiale til å revolusjonere miljøovervåkning ...
    • Environmental DNA filtration techniques affect recovered biodiversity 

      Majaneva, Markus; Diserud, Ola Håvard; Eagle, Shannon; Boström, Erik; Hajibabaei, Mehrdad; Ekrem, Torbjørn (Journal article; Peer reviewed, 2018)
      Freshwater metazoan biodiversity assessment using environmental DNA (eDNA) captured on filters offers new opportunities for water quality management. Filtering of water in the field is a logistical advantage compared to ...
    • Mamiellophyceae shift in seasonal predominance in the Baltic Sea 

      Majaneva, Markus; Enberg, Sara; Autio, Riitta; Blomster, Jaanika; Rintala, Janne-Markus (Journal article; Peer reviewed, 2019)
      The green algae Mamiellophyceae are a group of marine picoeukaryotes. We studied the succession of Mamiellophyceae in the Baltic Sea water column and ice from autumn to summer, using the hypervariable V4 region of the 18S ...
