I am an ecosystem ecologist with a passion for high latitude ecosystems and interested in the interplay of plants and their environment. My work in arctic tundra and peatlands focuses on belowground plant processes, such as root phenology and root production, and often includes measurements outside the summer season.

Some of my current projects are outlined below.

 

ALTER (Abisko Long-term Tundra Experimental Research)

Climate warming leads to large changes in species composition in arctic tundra, mainly through encroachment of shrubs and trees. Plants associate with different types of symbiotic soil fungi, mycorrhizae, and changes in plant community composition will translate into changes in the abundance of different types of fungi. These changes are likely to impact ecosystem processes more strongly than direct abiotic effects. Together with my collaborators, I have set up a mycorrhizal functional type removal experiment in which we group diverse plant species according to their (symbiotic) association with mycorrhizae and selectively remove plants with specific mycorrhizal associations from the plant community and compare this to a control treatment of random plant species removal. I focus on how root dynamics and decomposition patterns are subsequently affected. Read more.

EcoROOT

Boreal ecosystems are shaped by two major, interacting global change factors: changes in the thickness of the snow cover in winter, and grazing by large herbivores (reindeer). The EcoClimate Experiment at the Oulanka Research Station is a large, long-term experiment which includes snow addition and removal, as well as herbivore exclosures in two habitats: a dry oligotrophic Scots pine forest and a nutrient rich fen site. My goal in this project is to study how reindeer grazing and changes in snow cover influence root dynamics and I will provide non-destructive monitoring data on root dynamics (production, phenology, mortality, turnover) to be linked with other biogeochemical processes at the site. Read more.

The EcoClimate experiment owned and maintained by the Oulanka Research Station (University of Oulu) under the leadership of Riku Paavola, and I additionally collaborate with Maria Väisänen (University of Oulu).

 

DIG-IT! Digitalisation of Natural Complexity to Solve Socially Relevant Ecological Problems

The most important tool for observing belowground plant activity in the field are so-called minirhizotrons, transparent tubes buried in the soil and a camera to take pictures of roots over time. However, until now the amount of data that could be collected was severely constrained by the extremely time-consuming manual analysis of the resulting images. A single image from complex field settings could easily take a full day to digitize. This means that the biggest obstacle for providing data on root dynamics in high temporal and spatial resolution is the digitization of minirhizotron images. Here, we aim to automate root image analysis with Artificial Intelligence (DCNNs), thus removing the bottleneck of image analysis. Read more.

Bo Peters, Juergen Kreyling (both University of Greifswald) and I lead the subproject ‘Roots’ within the large framework of the DIG-IT! Project.
