Climate warming feedback from mountain birch forest expansion: Reduced albedo dominates carbon uptake
de Wit, Heleen; Bryn, Anders; Hofgaard, Annika; Karstensen, Jonas; Kvalevåg, Maria Malene; Peters, Glen Philip (Journal article; Peer reviewed, 2013)Expanding high elevation and high latitude forest has contrasting climate feedbacks through carbon sequestration (cooling) and reduced surface reflectance (warming), which are yet poorly quantified. Here, we present an ... -
Reliability in distribution modeling — A synthesis and step-by-step guidelines for improved practice
Bryn, Anders; Bekkby, Trine; Rinde, Eli; Gundersen, Hege; Halvorsen, Rune (Peer reviewed; Journal article, 2021)Information about the distribution of a study object (e.g., species or habitat) is essential in face of increasing pressure from land or sea use, and climate change. Distribution models are instrumental for acquiring such ...
