Gunnar Austrheim
Background and activities
My main interest in conservation biology and plant ecology has been how anthropogenic processes affect biodiversity, ecosystem functions and services at different spatio-temporal scales.
My expertise is primarily within alpine, semi-natural and boreal (coniferous and deciduous forest) ecosystems focusing on how land use processes in interaction with climate affects biodiversity components as well as supporting, regulating and provisioning services. Experiences from interdisciplinary projects have provided insight in the science-policy interface and how e.g. socio-economic drivers indirectly affect biodiversity and ES and how people perceive and respond to these changes. Much of this interdisciplinary work has focused on the ecosystem impact of domestic livestock and wild ungulates but also how the management of large herbivore ecosystem engineers interacts with societal processes.
