Associational relationships at multiple spatial scales affect forest damage by moose
Herfindal, Ivar; Tremblay, Jean-Pierre; Hester, Alison J.; Lande, Unni Støbet; Wam, Hilde K (Journal article; Peer reviewed, 2015)Increasing abundance of large herbivores combined with changes in forestry practices has led to increased forest damage in many temperate and boreal forest areas. The role of alternative forage as a driver for browsing ... -
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 ... -
Herbivory and climate as drivers of woody plant growth: Do deer decrease the impacts of warming?
Vuorinen, Katariina; Rao, Shaila; Hester, Alison J.; Speed, James David Mervyn (Peer reviewed; Journal article, 2020)Vegetation at ecotone transitions between open and forested areas is often heavily affected by two key processes: climate change and management of large herbivore densities. These both drive woody plant state shifts, ... -
The Response of Alpine Salix Shrubs to Long-Term Browsing Varies with Elevation and Herbivore Density
Speed, James David Mervyn; Austrheim, Gunnar; Hester, Alison J.; Mysterud, Atle (Journal article; Peer reviewed, 2013)The widespread expansion of shrubs into arctic and alpine regions has frequently been linked to climatic warming, but herbivory can play a role in addition to, or in interaction with, climate. Willow (Salix spp.) shrubs ...
