A post doc position is available at Terrestrial Ecology Section, Department of
Biology, University of Copenhagen with a starting date May 1st, 2022 or as
soon as possible thereafter. The initial appointment is for 2 years with a
possibility for extension.
Plants defend themselves against insect herbivory by releasing climate-
relevant volatile organic compounds (VOCs) to the atmosphere. Herbivore
damage alters VOC emission blends and increases the emission rates from the
affected ecosystem to the atmosphere. The total effect of herbivory on VOC
fluxes is likely to be considerable, at least periodically, but still this is
not accounted for in the current models. The aim of this project is to assess
effects of insect herbivory on VOC emissions in the rapidly warming high
latitude regions, where herbivory pressure is increasing with climate change.
We will quantify ecosystem-scale VOC emissions of a Subarctic mountain birch
forest during several growing seasons, while monitoring insect herbivory
intensity and the environmental conditions. We will also use modeling
approaches to assess the importance of herbivory for regional VOC emissions as
well as their impacts on atmospheric chemistry under different climate
scenarios. This will improve our understanding of the plant-stress-related
The position is available in the Ecosystem-Atmosphere Interactions Research
Group, led by Professor Riikka Rinnan. The group consists of 5-10 other
research staff members plus a number of students is physically located in
Copenhagen, Denmark. The group uses state-of-the-science techniques, such as
proton-transfer-reaction time-of-flight mass-spectrometry (PTR-TOF-MS) and
gas chromatography-mass spectrometry (GC-MS) for measurement of VOC
emissions from plants, emissions and uptake by soils, and their exchange at
the ecosystem scale. The group conducts experiments in the laboratory and in
the field, predominantly in the arctic environments. The research project is
collaboration with Dr. Thomas Holst, Prof. Lars Eklundh, and Dr. Jing Tang,
Lund University, Sweden.
Main tasks and responsibilities
The post doc will participate in conducting Eddy Covariance measurements of
VOCs and CO2 in a birch forest in Northern Sweden using the PTR-TOF-MS and a
CO2 analyser. The gas flux measurements are coupled to remote sensing of the
vegetation phenology using spectral censors and surface temperatures using
thermal imaging. The post doc can also participate in branch/stem/forest floor
measurements in the forest as well as modeling. The actual tasks will be
agreed upon based on the expertise and interests of the applicant.
The successful candidate will be responsible for data collection, processing
and interpretation as well as lead-writing scientific publications. The
candidate will have the opportunity to supervise MSc students. The candidate
should be willing to join for field work in Northern Sweden.
We are looking for ambitious and highly motivated candidates with a PhD in
biology/ecology, physical geography, meteorology, chemistry, or a related
field. Fluency in written and spoken English is a requirement, as well as
excellent writing skills demonstrated by the publication record. A successful
candidate also has some experience with quantification of VOCs using GC-MS or
PTR-MS techniques or eddy covariance measurements of CO2 or CH4. Skills and
interest in instrument handling, programming, and multivariate statistics are
assets. The candidate can take decisions independently, but she/he is also
comfortable working in teams and has a collaborative mindset. A driver's
license is needed to access the field site.
