Field course with students from Lund University, Sweden, and the University of Rwanda visiting Rubona field site

PhD student course entitled “Tropical tree eco(physio)logy: field methods and data analyses” held at the University of Rwanda, Huye campus, 6-11 February 2023

PhD class visiting Nyungwe forest

Tired but happy students returning from a field day at Rubona site

Olivier is discussing and planning coming field work in a collaborative project with Lina Mercado and Santiago Clerici, University of Exeter, UK.

Göran Wallin has been on sabbatical since April at Yadvinder Mahli's group, Ecosystem lab, University of Oxford, https://www.oxfordecosystems.org

Rwanda TREE that was broadcasted on national Rwandan television to celebrate the launch of the 2022/23 Forest Planting Season. The part about Rwanda TREE 9is 4-5 minutes and starts at 9:10 in the French version (https://youtu.be/568X4EY83WI) and at 24:00 in the Kinyarwandan version (https://youtu.be/Q3XUYAMPIy4).

Dr Maria Wittemann celebrating her new PhD title after a successful defense on 30th September!

Maria is nailing her PhD thesis 'Thermal plasticity and limitations in tropical trees' on 9th September.

Myriam and Brigitte studying photosynthetic heat tolerance using IR lamps and chlorophyll fluorimetry.

Brigitte is making a gas exchange measurement on two leaves from each of the harvested trees, directly after the tree and branch has been cut.

Lots of samples are collected each day on our 1000-tree harvest (20% of the trees in the plantations).

Felicien leading the team on branch/leaf level work at the harvest, here at Sigira site.

Olivier is staring up another sap flow measurement campaign on trees in Makera during the dry period, early June to early September.

Myriam and Brigitte measuring gas exchange of leaves on branches cut (and re-cut under water) from freshly harvested trees.

Felicien separating leaves and wood from sampled branches to estimate whole-tree leaf area and mass.

Athanase measuring the fresh mass of branches.

Some trees were small, others BIG!!! Here the stem base of a five year-old Polycias fulva tree in Rubona, together with Johan's sunglasses.

Partial harvest of 20% of the trees in Rwanda TREE (>1000 trees) began on May 23rd and will last for nine weeks, three at each site. Left: Nkuba (cutting trees), right: Bercare (measuring stems).

Some of us at the dissertation of Johanna Lethin at the University of Gothenburg. Etienne Zibera (to the right) is visiting Sweden to take the course "Plant ecophysiology in a global change perspective".
