The BAIE group wants to say goodbye to Mirco Migliavacca our group leader until 31.08.2021. It was a great time and experience to work together with you (which will be continued in the future of course). We wish you all the best for your new position at the JRC in Ispra.

We say goodbye this month to our guest Ladislav Sigut who stayed with us the whole last year as visiting PostDoc, working on foodprint heterogeneity of Eddy Covariance data. He is now returning to his home institution Czech Globe. It was a pleasure to us to have you here, looking forward to see you again in the future!

The good news is, that Qian Zhang who also stayed with us last year as visiting PostDoc, is back and will continue to work with us on Solar-Induced Chlorophyll Fluorescence Observation! Welcome back!

In the weeks of July 5, 2021 to July 16, 2021 various BAIE members (and other institute members) participated in an outdoor first aid course and rescuing from height. The three to four day long course took place in Schieferpark close to Lehesten and at the long term eddy covariance station Wetzstein. The members learned theory and practice of helping friends and colleagues in the field in case of accidents. And more importantly what measures to take to avoid such accidents to happen.

Lot's of media attention on the latest paper of Tarek S. El-Madany in collaboration with many people from our BAIE-community. Find the original paper on How Nitrogen and Phosphorus Availability Change Water Use Efficiency in a Mediterranean Savanna Ecosystem or choose between english AGU Science news, and german summaries covered by MPG news and the Initiative Wissenschaftsjahr.

While most of us were at EGU - other members of the BAIE Group and Freiland went to a two-week fieldwork to Majadas de Tieter to install a passive L-Band microwave radiometer (ELBARA) together with tree water content-, tree temperature- plus leaf wetness-, temperature, and relative humidity sensors at the surface of the herbaceous layer. This instrumental effort is part of the LCC (Land Carbon Constallation project (link to the homepage)).

Our visiting group member Quian Zhang together with Javier Pacheco published an article on Ground-Based Multiangle Solar-Induced Chlorophyll Fluorescence Observation and Angular Normalization for Assessing Crop Productivity. If you wanna learn more about angular effects on SIF and how normalization of both red and far-red SIF measurements improved correlation of SIF with GPP find all the information open access.

Successful PhD defense of Yunpeng

On Friday 26.03.2021, Yunpeng Luo successfully defended his PhD thesis on "Unexplored drivers of plant phenology: Beyond climate"! Congratulations Yunpeng!

January 2021:

Happy New Year everyone!

As always the year begins with EGU abstract submission deadline on January 13th. This years EGU will be fully online again - nevertheless we are looking forward to seeing you and your work in April this year - hopefully in our session.

Abstracts welcome for our Session BG3.21 Emerging constraints of photosynthesis (including chlorophyll fluorescence), respiration, and transpiration at ecosystem to global scales with Karolina Sakowska, Mirco Migliavacca and Markus Reichstein among the Conveners!

October 2020:

Only one year after she joined our group, Wantong already finished her first study and has currently a preprint under revision on the topic Revisiting global vegetation controls using multi-layer soil moisture. Congratulations Wantong!

Tarek and David’s were in the field today - at our research site Leinefelde where we collaborate with Alexander Knohl from Göttingen University. They collected our fluorescence box (FloX) that was installed there over the summer - enabling us the continous observation of chlorophyll fluorescence of the local beech forest.

Check out these two recently published articles with contributions from Mirco and Tarek:

Ecosystem transpiration and evaporation: Insights from three water flux partitioning methods across FLUXNET sites

Advances in hyperspectral remote sensing of vegetation traits and functions

Beech forest in Leinefelde

September 2020:

Ulisse Gomarasca and Ladislav Sigut started last week as PhD student and visiting scientist, respectively. Welcome!!

Last week some members were taking climbing classes to be safe in the field the day we can return to Majadas for field work and maintenance - which will hopefully be soon ...

Tarek's paper on the effects of heatwave 2018 has been published: “Drought and heatwave impacts on semi-arid ecosystems’ carbon fluxes along a precipitation gradient”. Available to read and download under this link .

What assumption do you make about the distribution of your soil CO2 efflux data? If you now start brooding over whether you ever checked - have a look why you should: in the new article from Thomas

Soil CO2 efflux errors are lognormally distributed – implications and guidance which is finally out!

May 2020:

Nutrients and water availability constrain the seasonality of vegetation activity in a Mediterranean ecosystem is the latest outcome from MANIP. In his analyses Yunpeng shows that seasonality of vegetation activity was altered after fertilization and the importance of nutrient–water interaction in this Mediterranean, water‐limited ecosystems. Always feel free to contact him if you have any questions related to the observed results.

May 2020

Ekaterina has been selected by the 'International Max Planck Research School for Global Biogeochemical Cycles' ( IMPRS gBGC) of our institute. This means after her time with us as an intern, she will stay at the institute and receive funding to do her PhD project. Congratulations Ekaterina!

Great to see that EGU2020 was a big success despite this new display format! We saw many interesting contributions and great discussions in the chats. Thank you all for joining our sessions and your interest in our displays. Hopefully next year, we will see each other again face to face! Displays will still be online, so in case you missed anything just have a look now!

Our former group member Xuanlong just published this very interesting technical note about Monitoring Plant Functional Diversity Using the Reflectance and Echo from Space.

For those who are more interested in latest results of Soil COS Exchange: Kitz et al. investigated the interactive role of solar radiation and soil organic matter in driving the direction and magnitude of soil COS exchange in three European Ecosystems.

And last but not least - an article from a former project of our group member Sinikka about Water Stable Isotopes in Ecohydrological Field Research: Comparison Between In Situ and Destructive Monitoring Methods to Determine Soil Water Isotopic Signatures also just got published in Frontiers.
