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.
