Eva Krab
I am a soil ecologist who is not only interested in the effects of a changing environment on ecosystem processes, but also very much in the mechanisms behind it. To get a better understanding of how environmental changes affect soil organisms and their activities, I focus on soil fauna, which are key players in many soil processes but are often overlooked by scientists.

Presentation

My main interests are to understand how environmental changes may induce changes in soil organism communities and to assess the consequences of community changes for soil processes. More specifically, I am interested to what extent environmental changes affect interactions between soil fauna, microorganisms and plants, and if changed interactions may lead to changes in carbon and nitrogen cycling. Most of my current projects are situated in arctic ecosystems, but I have recently been expanding my research into the boreal forest.

I try to answer my research questions using different approaches at different scales, e.g. in the laboratory, using mesocosms and small scale field experiments, and by larger-scale field sampling campaigns. Recent work includes i) studying the effects of thawing permafrost and changes in frost-induced soil mixing on carbon and nitrogen dynamics, ii) how alterations in (winter)climate and shrub expansion may affect soil invertebrates and their contribution to ecosystem processes and iii) effects of earthworm invasions into the subarctic. Also I am involved in a project optimizing sampling strategies for soil microorganisms and the development of molecular methods for assessing soil fauna diversity.

Teaching

I am course coordinator for the master-course: 'Soil Biology and Biogeochemical Cycles (15 ECTS)' running yearly during January-March.

Cooperation

I am a part of the Soil Biology group at the Department of Soil and Environment lead by Prof. Björn Lindahl.

In my current projects I collaborate with researchers at SLU Uppsala, Umeå University, University of Copenhagen, University of Oulu, VU University Amsterdam, University of Tromsö, University of Greifswald and EPFL (Lausanne).

I am an affiliated researcher with the Climate Impacts Research Centre (CIRC) in Abisko, Sweden (Umeå University)

Supervision

I am a co-supervisor of doctoral student Tarquin Netherway at the department of Ecology (SLU Uppsala)
