Ecosystem-Atmosphere Interactions – Rinnan Lab
The Rinnan Lab explores the controls on the exchange of biogenic volatile organic compounds (BVOCs) between ecosystems and the atmosphere. We use state-of-the-science techniques for measurement of BVOC emissions from plants, emissions and uptake by soils, and their exchange at the ecosystem scale. We conduct experiments in the laboratory and in the field, predominantly in the arctic environments.
Riikka Rinnan is a professor in the Terrestrial Ecology Section, Department of Biology and a principal investigator at the Center for Permafrost (CENPERM), University of Copenhagen, Denmark. For other group members, scroll down on this page.
Arctic ecosystem ecology and ecosystem-atmosphere interactions
- Environmental and plant trait-based controls on BVOC emissions from tundra shrubs
- BVOC emissions from soils and permafrost, coupling to soil respiration and methane fluxes, and the role of microbial community composition
- BVOC uptake by soil microorganisms, coupling to soil respiration and methane oxidation, and the role of microbial community composition
- Bidirectional exchange (emissions and uptake) of BVOCs in tundra ecosystems under climate change and the effects of changing plant community composition
- Insect herbivory effects on birch and willow volatile defenses, and their interactions with climate change
- Ecosystem-scale BVOC fluxes measured by eddy covariance techniques
- Effects of climate change and biotic stress on BVOC emissions at the regional scale, assessed by modeling approaches
Funding from the European Research Council consolidator grant Tundra biogenic volatile emissions in the 21st century (TUVOLU) (2018-2023), H2020 Marie Curie Actions, The Danish Council for Independent Research | Natural Sciences (Sapere aude -program), and the Center of Excellence funded by the Danish National Research Foundation: Center for Permafrost (CENPERM).
Eucalypt volatiles
- Between-species differences in constitutive BVOC emissions of eucalypts
- Effects of increasing CO2 concentration and climate warming on eucalypt volatiles
- Effects of herbivory on Eucalyptus volatile blends
Collaboration with Elizabeth Heather Jakobsen Neilson, Department of Plant and Environmental Sciences, University of Copenhagen.
PTR-TOF-1000 ultra (Ionicon)
proton-transfer-reaction time-of-flight mass-spectrometer
We conduct experiments with real-time analysis of VOCs in the laboratory and in the field. We have two PTR-TOF-1000 ultra-instruments; one with Selective Reagent Ionization technology. Our instruments have been operated e.g. in Abisko, Northern Sweden and at Finse Alpine Research Station in Norway measuring eddy covariance fluxes.
GC-MS (Agilent), TD100-xr (Markes)
gas chromatograph-mass spectrometer coupled with a thermal desorber
We also analyse biogenic volatiles by trapping the volatiles (~C5-C25) in adsorbent cartridges, which are later analyzed by GC-MS after thermal desorption.
Custom-built climate chambers
We have six climate chambers with Valoya LED lighting and a built-in system for gas flux monitoring that allows for temperature manipulation from below freezing to 30°C.
NIR-spectrometer
Antaris II near infrared reflectance spectrometer, Thermo Scientific
An instrument used mainly for fingerprinting chemical composition of solid samples.

If you are interested in making a project in biosphere-atmosphere gas exchange, plant ecophysiology or plant-soil interactions, you are welcome to contact Riikka Rinnan! If you have a general idea of the topic, we can develop it into an exciting project. Quite often, we also have ready-made plans that are only waiting for the right person to arrive. There are both laboratory- and field-based, as well as modeling, projects available.
Every summer we send field assistants to exciting locations, for example in Greenland or Northern Sweden. Contact Riikka Rinnan for possibilities!
