Continuous and discontinuous variation in ecosystem carbon stocks with elevation across a treeline ecotone
Speed, James David Mervyn; Martinsen, Vegard; Hester, Alison J.; Holand, Øystein; Mulder, Jan; Mysterud, Atle; Austrheim, Gunnar (Journal article; Peer reviewed, 2015)Treelines differentiate vastly contrasting ecosystems: open tundra from closed forest. Treeline advance has implications for the climate system due to the impact of the transition from tundra to forest ecosystem on ... -
Long-Term Increase in Aboveground Carbon Stocks Following Exclusion of Grazers and Forest Establishment in an Alpine Ecosystem
Speed, James David Mervyn; Martinsen, Vegard; Mysterud, Atle; Mulder, Jan; Holand, Øystein; Austrheim, Gunnar (Journal article; Peer reviewed, 2014)Ecosystem stores of carbon are a key component in the global carbon cycle. Many studies have examined the impact of climate change on ecosystem carbon storage, but few have investigated the impact of land-use change and ... -
Stabilizing selection and adaptive evolution in a combination of two traits in an arctic ungulate
Holand, Håkon; Kvalnes, Thomas; Røed, Knut; Holand, Øystein; Sæther, Bernt-Erik; Kumpula, Jukka (Journal article; Peer reviewed, 2020)Stabilizing selection is thought to be common in wild populations and act as one of the main evolutionary mechanisms, which constrain phenotypic variation. When multiple traits interact to create a combined phenotype, ... -
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 ...
