• Analyzing dynamic species abundance distributions using generalized linear mixed models 

      Solbu, Erik Blystad; van der Veen, Bert; Herfindal, Ivar; Hovstad, Knut Anders (Peer reviewed; Journal article, 2022-05-12)
      Understanding the mechanisms of ecological community dynamics and how they could be affected by environmental changes is important. Population dynamic models have well known ecological parameters that describe key ...
    • Ivaretagelse av ville pollinatorer og planter tilknyttet kulturlandskapet i byutviklingen. Oppsummering av forskningsprosjektet BE(E) DIVERSE 

      Johansen, Line; Albertsen, Elena; Bär, Annette; Hanslin, Hans Martin; Herfindal, Ivar; van der Veen, Bert; Henriksen, Marie Vestergaard; Vinge, Heidi; Wehn, Sølvi; Solbu, Erik (NIBIO Rapport, Research report, 2023)
      Det er en global nedgang av ville pollinatorer, og hovedårsaken til dette er at leveområdene deres er under press og går tapt på grunn av urbanisering og andre arealendringer. I BE(E) DIVERSE prosjektet har vi derfor studert ...
    • Model-based ordination for species with unequal niche widths 

      van der Veen, Bert; Hui, Francis K. C.; Hovstad, Knut Anders; Solbu, Erik Blystad; OHara, Robert Brian (Peer reviewed; Journal article, 2021-03-25)
      1. It is common practice for ecologists to examine species niches in the study of community composition. The response curve of a species in the fundamental niche is usually assumed to be quadratic. The centre of a quadratic ...
    • Modelling temperature-driven changes in species associations across freshwater communities 

      Perrin, Sam; van der Veen, Bert; Golding, Nick; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2021-10-20)
      Due to global climate change–induced shifts in species distributions, estimating changes in community composition through the use of Species Distribution Models has become a key management tool. Being able to determine how ...
    • A re-analysis of NH4+ sorption on biochar: Have expectations been too high? 

      Weldon, Simon Mark; van der Veen, Bert; Farkas, Eva; Kocatürk Schumacher, Nazli Pelin; Dieguez-Alonso, Alba; Budai, Alice Erzebet; Rasse, Daniel (Peer reviewed; Journal article, 2022-04-22)
      Sorption of nutrients such as NH4+ is often quoted as a critical property of biochar, explaining its value as a soil amendment and a filter material. However, published values for NH4+ sorption to biochar vary by more than ...
    • Refrigeration or anti-theft? Food-caching behavior of Wolverines (Gulo gulo) in Scandinavia 

      van der Veen, Bert; Mattisson, Jenny; Zimmermann, Barbara; Odden, John; Persson, Jens (Peer reviewed; Journal article, 2020-04-15)
      Food-caching animals can gain nutritional advantages by buffering seasonality in food availability, especially during times of scarcity. The wolverine (Gulo gulo) is a facultative predator that occupies environments of low ...
