How boreal forests and other boreal ecosystems work?
How climate change affects boreal forests?
How environment affects the physiology and photosynthesis of an individual tree?
What are the effects of forests on climate?
Due to climate change, for example, the winters of boreal areas will become milder and we can expect changes in the strength, duration and frequency of dry spells. These factors have important impacts on the growth and metabolism of trees and other plants. On the other hand, trees contribute to the climate by absorbing atmospheric carbon, by transpiring water, by participating to cloud formation and by reflecting radiation from the surface of the planet. In addition, forest actively store a huge amount of carbon in the tree trunks and forest soil.
Our research concentrates on the role of vegetation in the fluxes of energy and matter in and between forests, atmosphere and water bodies. We also aim to understand the functions and responses in detail on tree level. We work in a multidisciplinary way, as our group consists of forest scientists, physicists, chemists and environmental scientists. This is also reflected in our wide range of research themes presented below.
We combine modelling, intensive field measurements and laboratory experiments. Our main study sites are the three Stations for Measuring Forest Ecosystem-Atmosphere Relations (SMEAR I, SMEAR II and SMEAR III), operating since 1991 (SMEAR I).
