2 PhD positions in ecology of aquatic-terrestrial interfaces

(Reference Number:27/13)

Background: The overarching goal of this project is to understand the regulation of organic
carbon transformation (OC) across terrestrial-aquatic interfaces from soil, to
lotic and lentic waters, with emphasis on ephemeral streams. We will target the
effects of (1) OC quality and priming, (2) stream sediment properties that
control the advective supply of hyporheic sediments with oxygen and nutrients,
and (3) the water regime. Our studies will contribute to the understanding of
OC mineralisation and thus CO2 emissions across terrestrial and
aquatic systems.

PhD projects
will build on a series of field and flume experiments conducted in an outdoor experimental area. Field work will be completed by small scaled laboratory experiments. Support by technician is available. PhD students will be based in the research groups of Katrin Premke at IGB Berlin and Michael Mutz at BTU, research station Bad Saarow near Berlin.

at IGB will have an emphasis on the quality of OC and priming effects for OC-transformations, position#2 at BTU on the significance
of sedimentary structures and advective supply of variable OC, nutrients and
redox partner for OC-transformations in the bed sediments. However, close
collaboration is expected throughout the project and this will involve common
field work at the experimental area and joint publications.

We are looking
for enthusiastic, highly motivated students with a Master’s degree or
equivalent in Aquatic Biology, Environmental Sciences, Environmental
biogeochemistry or a related field. Background in stream/lake ecology, geomorphology,
and/or molecular ecology is an asset but not mandatory. For the successful
realization of the project, flexibility, autonomy, communication skills, and
teamwork are required. Field work can be challenging during adverse weather
conditions. A clean driving license is essential for this project.

We offer
an exciting interdisciplinary project at the interface of aquatic and
terrestrial biogeochemistry within a young, international and dynamic team. The
positions are fixed-term and limited to 3 years. Start
of the project would be latest from August 2013. The salary will be set
according to the German collective labor agreement of German public employees
(Tarifvertrag für den öffentlichen Dienst der Länder) TV-L E 13 (BtU) and 13 TVÖD (IGB). The allocation of the position is under budget reservation. In keeping with the BTU’s and IGB's policies regarding gender equity,
female applicants are particularly encouraged. Disabled people with identical
qualifications will be favoured.
