Johannes Edvardsson

Since 2017, I am employed as researcher at the Department of Geology, Lund University, and my field of excellence is in dendrochronology (tree-ring research), peatland development, long-term (hydro)climatology, and quaternary sciences. In my research, I have been using growth patterns of trees to study and date large-scale climate changes, hydrological shifts in peatlands, avalanches, historical buildings, archaeological artefacts, and 17th century Flemish art. One of the primary aims of my on-going research is to study what effects tree colonization in peatlands have on hydrology, vegetation, and carbon sequestration in such ecosystems. To answer my research questions, I’ll use data generated from living and subfossil peatland trees, as well as approaches including laser ablation spot analysis (LA-ICP-MS) and stable isotope analyses (δ13C and δ18O). I will also perform field studies of changes in moisture content in peat soils representing different tree coverage, compile and analyse data from an existing network of sites where changes in peatland water tables, tree growth, and carbon fluxes have been monitored, and use examine tree growth responses to environmental changes and the on-going tree colonization. My research has mainly been financed through grant from the Swedish Research Council (VR) and Crafoordska stiftelsen. 

On-going and earlier collaborations

Blue Archaeology

Blue Archaeology is a multi-disciplinary project assembling the cultural and natural heritage of submerged Stone-Age Seascapes, foremost along the eastern coast of Sweden. 

BECC (Biodiversity and Ecosystem Services in a Changing Climate)

BECC is a collaboration between Lund University and University of Gothenburg. It is a strategic research area that strives for a better understanding of the impacts of climate change and land use decisions on terrestrial ecosystems and biodiversity. Since 2017, I am principal investigator (PI) within the research groups encompassed by BECC.

Jordaens, Van Dyck, Panel Paintings Project (JVDPPP)

The JVDPPP is an innovative art historical initiative, which among many research methods use tree-ring studies of c. 300 Flemish 17th century paintings to investigate collaborations between the Flemish masters J. Jordaens and Sir. A. Van Dyck. In this project, I work as a consultant dendrochronologist with art researcher at the Royal Museum of Fine Arts in Belgium.

Swiss Tree-Ring Laboratory

Between 2013 and 2016, I had a 3-year postdoctoral employment at the Swiss Tree-Ring Laboratory. I was working in an international and interdisciplinary project named CLIMPEAT and still have on-going collaborations with several researchers at the Swiss Tree-Ring Laboratory. 

CLIMPEAT

The CLIMPEAT-project is an international and interdisciplinary Swiss-Lithuanian research collaboration aiming to explore the interconnections and interdependencies of peatlands ecosystems with climate (change), anthropogenic activity and sequestered carbon. In this project, I have close collaborations with researchers at the Swiss Tree-Ring Laboratory, Nature Research Centre (Vilnius), and Vilnius University.
