    • Annual ring growth of a widespread high arctic shrub reflects past fluctuations in community‐level plant biomass 

      Le Moullec, Mathilde; Buchwal, Agata; van der Wal, René; Sandal, Lisa; Hansen, Brage Bremset (Journal article; Peer reviewed, 2018)
      1. Long time series of primary production are rarely available, restricting our mechanistic understanding of vegetation and ecosystem dynamics under climate change. Dendrochronological tools are increasingly used instead, ...

    • Effects of density, species interactions, and environmental stochasticity on the dynamics of British bird communities 

      Sandal, Lisa; Grøtan, Vidar; Sæther, Bernt-Erik; Freckleton, Robert P.; Noble, David G.; Ovaskainen, Otso (Journal article; Peer reviewed, 2022)
      Our knowledge of the factors affecting species abundances is mainly based on time-series analyses of a few well-studied species at single or few localities, but we know little about whether results from such analyses can ...

    • Growth rings show limited evidence for ungulates’ potential to suppress shrubs across the Arctic 

      Vuorinen, Katariina Elsa Maria; Austrheim, Gunnar; Tremblay, Jean-Pierre; Myers-Smith, Isla H.; Hortman, Hans Ivar; Frank, Peter; Barrio, Isabel C.; Dalerum, Fredrik; Björkman, Mats Peter; Björk, Robert G.; Ehrich, Dorothee; Sokolov, Aleksandr; Sokolova, Natalya; Ropars, Pascale; Boudreau, Stephane; Normand, Signe; Prendin, Angela L.; Schmidt, Niels Martin; Pacheco-Solana, Arturo; Post, Eric; John, Christian; Kerby, Jeff; Sullivan, Patrick F.; Le Moullec, Mathilde; Hansen, Brage Bremset; van der Wal, René; Pedersen, Åshild Ønvik; Sandal, Lisa; Gough, Laura; Young, Amanda; Li, Bingxi; Magnusson, Runa I.; Sass-Klaassen, Ute; Buchwal, Agata; Welker, Jeffrey; Grogan, Paul; Andruko, Rhett; Morrissette-Boileau, Clara; Volkovitskiy, Alexander; Terekhina, Alexandra; Speed, James David Mervyn (Peer reviewed; Journal article, 2022)
      Global warming has pronounced effects on tundra vegetation, and rising mean temperatures increase plant growth potential across the Arctic biome. Herbivores may counteract the warming impacts by reducing plant growth, but ...

    • Spatiotemporal dynamics of avian communities 

      Sandal, Lisa (Doctoral thesis, 2023)
      Community ecology is the study of how different species interact with each other and their environment in a given habitat. In the face of rapid biodiversity loss, community ecology studies are more important than ever. ...

    • Spatiotemporal patterns of plant growth in a warming high Arctic: insights from dendrochronology of Salix polaris 

      Sandal, Lisa (Master thesis, 2017)
      Climate change is most pronounced at high latitudes, where plant and animal populations are often strongly regulated by environmental drivers. Theory suggests that if these environmental drivers are synchronized over large ...
