Gothenburg University
Alpine and Polar Ecology
I’m a researcher within Ecosystem Science, focusing on current and future changes in cold regions. I have a background in Biology, Environmental and Atmospheric science connected to biosphere-atmosphere as well as cryosphere-atmosphere interaction and exchange processes. My research interest spans from changes in vegetation and soil microbial composition to changes in the carbon and nutrient cycles, but also includes the chemical, physical and biological processes of seasonal snow.

I am a researcher in ecosystem sciences. I am interested in the influence of snow cover on vegetation distribution and soil microbial composition and how this interaction influences the spatial and temporal patterns of carbon and nutrient cycles in the arctic tundra. I am combining field experiments with remote sensing and modelling techniques.

I am a plant ecologist with a passion for the ecosystems of cold areas. I am fascinated by their characteristic plant communities and by the plants’ abilities to survive harsh conditions through manipulation of their neighbours and their micro-environment. My research therefore aims to answer questions such as how do plants and their interactions control ecological processes, how do different plant species or groups of plants vary in their responses to climate change or their effects on ecosystem functioning, and what does this means for the feedbacks of northern ecosystems to climate change. To address these questions, I use controlled mesocosm and plot-studies in the greenhouse and experimental garden as well as experimental manipulation of climate and vegetation at the plot scale and studies along natural climate gradients in the field. Experimental sites are located in northern Sweden, both in the subarctic tundra near Abisko (68°21’N, 18°49’E) and in the Boreal forest near Arvidsjaur (65°59’N, 19°28’E).

I am an ecologist and biochemist with a strong interest in northern ecosystems and their responses to climate change. I have been working on geothermally warmed ecosystems in Iceland, unraveling long-term warming effects on the ecosystem C and N cycle and on plant physiology. I am investigating the role of winter processes in plant and microbial carbon transformations and plant physiology and activity with a special focus on responses to snow cover changes (an important factor of climate change at high latitudes).

During my postdoc at CIRC, we united tundra warming experiments where respiration flux data were measured into the tundra flux database. We used the database to study the effects of warming on growing-season ecosystem respiration, and the underlying drivers of variation in the warming response. As an ecologist, I am profoundly interested in the functioning of natural ecosystems worldwide, their resilience to increasing disturbances, and how this resilience affects restoration performance. When I am off scientific duty, I am mostly to be found outside, enjoying nature’s sounds and sights.

I am an enthusiastic spatial ecologist that works on decomposition and vegetation assembly processes. I am part of the global tea bag index team and work as an associate professor at Umeå University.

I am plant ecologist with a strong focus on belowground ecology. I am studying the effects of climate change on the decomposition on a regional (arctic) to global scale. In a future warmer environment, it is thought that microbes become more active and break up biomass quicker and more carbon is released into the atmosphere in form of CO2 and methane. However, climate change is a bit more complex than that, and the problem is that we don’t have a clear idea of how all the different factors that are changing with climate warming will interact and affect the different stages of decomposition.
