PaTreME · Partioning Tree Methane Emissions

Partioning Tree Methane Emissions

The scientific aim of the project PaTreME was to quantify the contribution of different source processes to methane emissions from plant surfaces. Other aims of the project were to facilitate my return and integration into the European Research area after working in Canada for over six years, bi-directional knowledge exchange with my Finnish host institution (stable isotope analysis, trace gas flux measurements), and my development towards academic independence. As described below, both the scientific and non-scientific work plan had to be adapted due to the CoViD pandemic and technical set-backs during the project. Nevertheless, I am confident that PaTreME made improtant contribution to the scientific field as well as to its other goals. The overall goals of PaTreME was to (a) develop a method to partitioning of plant methane emissions from different source processes (aerobic methane production (AMP), soil methane export (SM), and endophytic microbial methane production (MMP)) using stable isotope, radiocarbon, and chemical tracer techniques, and (b) apply this method to partition the methane fluxes at the SMEAR II boreal forest station. The scientific work in PaTreME was to be organized in four work packages with the following objectives: 1. Develop an enclosure chamber system for isotope analysis of plant methane emissions; 2. Identify characteristic isotope and methane:methanol values of methane source processes; 3. Measure isotope and methane:methanol values of methane emitted by boreal trees at the SMEAR II research forest; 4. Develop and apply an isotope partitioning model to quantify methane emissions from AMP, SM, and MMP. In addition, a fifth WP was dedicated to training, career development, and research communication activities.
