  • An approach based on the total-species accumulation curve and higher taxon richness to estimate realistic upper limits in regional species richness 
    Bevilacqua, Stanislao; Ugland, Karl Inne; Plicanti, Adriana; Scuderi, Danilo; Terlizzi, Antonio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Most of accumulation curves tend to underestimate species richness, as they do not consider spatial heterogeneity in species distribution, or are structured to provide lower bound estimates and limited extrapolations. The ...
  • Social behaviour in mesopelagic jellyfish 
    Kaartvedt, Stein; Ugland, Karl Inne; Klevjer, Thor A.; Røstad, Anders; Titelman, Josefin; Solberg, Ingrid (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Gelatinous organisms apparently play a central role in deep pelagic ecosystems, but lack of observational methodologies has restricted information on their behaviour. We made acoustic records of diel migrating jellyfish ...
  • Temporal and Spatial Dynamics of Diatom (Bacillariophyceae) Communities in a Peatland Area 
    Mutinova, Petra Thea; Kulichova, Jana; Ugland, Karl Inne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    This study was conducted to simultaneously investigate the spatial and temporal dynamics of diatom communities inhabiting two microhabitat types (Sphagnum periphyton and epipelon) in a peatland area of the Czech Republic. ...
  • Upscaling biodiversity: estimating the species-area relationship from small samples 
    Kunin, William E.; Harte, John; He, Fangliang; Hui, Cang; Jobe, R. Todd; Ostling, Annette; Polce, Chiara; Sizling, Arnost; Smith, Adam B.; Smith, Krister; Smart, Simon M; Storch, David; Tjørve, Even; Ugland, Karl Inne; Ulrich, Werner; Varma, Varun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The challenge of biodiversity upscaling, estimating the species richness of a large area from scattered local surveys within it, has attracted increasing interest in recent years, producing a wide range of competing ...
