    • Legacy effects of herbivory on treeline dynamics along an elevational gradient 

      Mienna, Ida Marielle; Austrheim, Gunnar; Klanderud, Kari; Bollandsås, Ole Martin; Speed, James David Mervyn (Peer reviewed; Journal article, 2022)
      Treelines are expected to expand into alpine ecosystems with global warming, but herbivory may delay this expansion. This study quantifies long-term effects of temporally varying sheep densities on birch recruitment and ...

    • Mapping and Estimating Aboveground Biomass in an Alpine Treeline Ecotone under Model-Based Inference 

      Mukhopadhyay, Ritwika; Næsset, Erik; Gobakken, Terje; Mienna, Ida Marielle; Candelas Bielza, Jaime; Austrheim, Gunnar; Persson, Henrik Jan; Ørka, Hans Ole; Roald, Bjørn-Eirik; Bollandsås, Ole Martin (Peer reviewed; Journal article, 2023)
      Due to climate change, treelines are moving to higher elevations and latitudes. The estimation of biomass of trees and shrubs advancing into alpine areas is necessary for carbon reporting. Remotely sensed (RS) data have ...

    • Patterns and Drivers of Phylogenetic Diversity and Endemism in the Norwegian Vascular Flora 

      Mienna, Ida Marielle (Master thesis, 2018)
      Biodiversity is commonly measured as the local abundance of discrete species. This approach fails to incorporate evolutionary relationships among species and gives an incomplete picture of the diversity in a given region. ...

    • The relative role of climate and herbivory in driving treeline dynamics along a latitudinal gradient 

      Mienna, Ida Marielle; Speed, James David Mervyn; Klanderud, Kari; Austrheim, Gunnar; Næsset, Erik; Bollandsås, Ole Martin (Peer reviewed; Journal article, 2020)
      Aim The treeline is an obvious ecotone between forest and tundra ecosystems. Climatic warming is expected to lead to the treeline advancing, although in many cases this has not been observed. This is most likely because ...

    • Spatial patterns of phylogenetic and species diversity of fennoscandian vascular plants in protected areas 

      Matten, Damaris Marina; Mienna, Ida Marielle; Bieker, Vanessa Carina; Mishler, Brent D; Moen, Victoria Stornes; Nygård, Malene Østreng; Vuorinen, Katariina Elsa M; Bendiksby, Mika; Martin, Michael David; Speed, James David Mervyn (Peer reviewed; Journal article, 2023)
      Protected areas are one of the main strategic means for conserving biodiversity. Yet, the design of protected areas usually neglects phylogenetic diversity, an important diversity measure. In this paper we assess the ...
