Airborne laser scanning reveals increased growth and complexity of boreal forest canopies across a network of ungulate exclosures in Norway
Kolstad, Anders Lorentzen; Snøan, Ingrid Bekken; Austrheim, Gunnar; Bollandsås, Ole Martin; Solberg, Erling Johan; Speed, James David Mervyn (Peer reviewed; Journal article, 2021)Large herbivores are often classed as ecosystem engineers, and when they become scarce or overabundant, this can alter ecosystem states and influence climate forcing potentials. This realization has spurred a call to ... -

Endret beitetrykk har effekter for planteegenskaper hos utvalgte boreale- og alpine arter : en etterundersøkelse etter 15 år langt beiteeksperiment
Straume, Lena (Master thesis, 2020)Beite er en viktig faktor som påvirker forekomst og egenskaper til mange plantearter. Denne studien er gjennomført som en etterstudie etter et 15 år langt beiteeksperiment med fravær av sau, lavt beitetrykk (25 sau per ... -

Speed, James David Mervyn; Martinsen, Vegard; Mysterud, Atle; Mulder, Jan; Holand, Øystein; Austrheim, Gunnar (Journal article; Peer reviewed, 2014) -
Mapping and Estimating Aboveground Biomass in an Alpine Treeline Ecotone under Model-Based Inference

Resilience of Alpine Salix shrubs to changes in browsing pressure
Palm, Marlene (Master thesis, 2020)Browsing by large herbivores has the potential to inhibit climate-driven shrub expansion. How resilient shrubs are to a change in herbivory, however, is not fully understood. In this study, I want to examine how Salix ... -
Sheep grazing effects on soil carbon and nitrogen and implications for runoff water quality at a low alpine site in southern Norway
Martinsen, Vegard (2011;2011:10, Doctoral thesis, 2011)Grazing in outlying fields has a long history and is important in local communities worldwide. Alpine ecosystems, representing a large proportion of the land area in Europe, are under pressure from changes in climate and ... -
Synergies and trade-offs between ecosystem services in analpine ecosystem grazed by sheep – An experimental approach
Austrheim, Gunnar; Speed, James David Mervyn; Evju, Marianne; Hester, Alison; Holand, Øystein; Loe, Leif Egil; Martinsen, Vegard; Mobæk, Ragnhild; Mulder, Jan; Steen, Harald; Thompson, Des B.A.; Mysterud, Atle (Journal article; Peer reviewed, 2016)Domestic livestock drives ecosystem changes in many of the world’s mountain regions, and can be the dominant influenceon soil, habitat and wildlife dynamics. Grazing impacts on ecosystem services (ES) vary according to ... -
