Chlorophyll fluorescence @FAIR tower

Had a fantastic day out at the FAIR tower site mounting active and passive chlorophyll fluorescence measurement devices together with Michaela, Albin and Klemens, who filmed our activities for the upcoming MSc study Ecology & Biodiversity movie.

Mesocosm fluorescence experiment started

After intensive preparations this week, today we started, within the frame of a joint FWF-DFG project with Mirco Migliavacca, a mesocosm experiment in which we aim to study the interactive effects of drought and canopy structure on the top-of-canopy sun-induced fluorescence. To this end, Javier Pacheco-Labrador joined with a FLOX-TOGO instrument for SIF measurements across the replicated plots on a planophile (clover) and erectophile (grass) canopy. These episodic measurements will be accompanied by a suite of additional measurements including active chlorophyll fluorescence, environmental conditions, leaf area, leaf angle distribution, leaf ingredients, etc. FormerMSCA fellow in our group, Karolina Sakowska, also joined for the day to help out, exchange data and discuss ongoing works!

Peru update

454fafcc-5463-4318-898a-68c99fa30463As vegetation development is progressing, Lorenz and Rolando are using our unique EcoBot for investigating spatial differences in energy partitioning between locally grown crops across the precipitation gradient from Cordillera blanca to negra just outside Huaraz.

Peru update

Llupa

The vegetation period is progressing at our study sites around Huaraz, as can be seen in the picture showing potatoe plants emerging at the EC flux tower site in Llupa.

Chincay

Meanwhile the new AWS has been set up in the Cordillera negra close to the village of Chincay.
