Overview

The Department Biogeochemical Processes explores the key processes and organisms that regulate exchanges of energy, water and elements between ecosystems and their surroundings. We use observations, experiments and models to improve understanding of how human activities are altering ecosystem function, and the consequences of those changes for sustainability and regional/global climate.

We explore several aspects of ecosystem function and how it is altered by climate and land use:

- Allocation of the products of photosynthesis among respiration, storage, growth, transfer to the rhizosphere and defense

- Factors determining the age and transit time of carbon in soils

- Links between microbial community function and the diversity of organic compounds and gases found in soils and groundwater

- Landscape scale processes such as windthrow, herbivory, and fire

- Understanding how environmental conditions are recored in the isotopic composition of biomarker molecules

December 13, 2018:
On Tuesday, Stefan Karlowsky successfully defended his PhD on "Mechanisms of Resistance and Resilience in the Plant-Soil System of Mountain Grassland Communinities”. Congratulations!

November 7, 2018:
Henrik Hartmann from our Plant Allocation group was a guest on the radio show "IQ - Wissenschaft und Forschung" von Bayern 2. He talked about how his love for trees awakened his desire to study and understand forest ecosystems. You can listen to the interview (in German) here (first part of the show).

November 1, 2018:
Jošt Lavrič is chairing a session at the EGU 2019 general assembly. The session is called "Intact Amazon forest – a natural laboratory of global significance (BG2.4 / AS3.35 / HS11.64 / SSS10.12)" and invites scientists from a range of Amazon-centered projects, including ATTO, to present their findings. Co-Conveners are Alessandro Araújo (EMBRAPA), Carlos Alberto Quesada (INPA), Matthias Sörgel (MPI-C). EGU19 takes place in Vienna (Austria) on 7–12 April, the deadline for abstract submission is 10 January 2019.

November 1, 2018:
Christie Goodale from Cornell University, Ithaca, NY is visiting the institute this week. She will give a talk in the BGC-Seminar today on "Nitrogen fate and effects on ecosystem carbon storage". Anyone interested in speaking with her should contact Sue Trumbore.

October 19, 2018:
We currently have two visiting scientists in our depart. Angelica Resende is a PhD student at the National Institute of Amazonian Research (INPA) in Manaus, Brazil and is here to measure 14C in trees. Renata Jou from the Federal University of Rio de Janeiro, Brazil is prepping soil samples for 14C analysis.

September 24, 2018:
Today, Jianbei Huang successfully defended his PhD on "Trade-offs between growth, storage and defense in plants under carbon limitation”. Congratulations!

September 10, 2018:
This week 14Constraint project group is hosting a “hack-a-thon” with colleagues from the Powell Center to work on the International Soil Radiocarbon Database (IsRad) and the publication announcing its official launch.
