On January 12th 2018 Hannah Weigand defended successfully her PhD thesis “Improving, applying and evaluating ddRAD sequencing for the detection of local adaptation to anthropogenic stressors in stream macroinvertebrates”. The thesis was part of the Junior Research Group project “GeneStream” funded by the Kurt Eberhard Bode-Foundation
Congrats to Jan Macher for successfully defending his PhD thesis on the “Development, testing and application of DNA-based methods to study freshwater invertebrate biodiversity under stress”.
Examiner were Prof. Dr. Ralph Tollrian (Ruhr University of Bochum, Prof. Dr. Jens Boenigk and Prof. Dr. Florian Leese. Chair of the committee was Prof. Dr. Daniel Hering.Photo: PhD committee and candidate. F.r.t.l.: Daniel Hering, Jens Boenigk, Florian Leese, Jan Macher, Ralph Tollrian
Congrats to Vasco for his highly successful defense of his PhD thesis entitled “Development of DNA metabarcoding methods for stream ecosystem assessment”.
The PhD committee consisted of the following examiners: Prof. Dr. Jens Boenigk, Prof. Dr. Simon Creer (University of Bangor, UK) and Florian Leese. Chair of the committe was Prof. Dr. Peter Haase.

On September 5th our new module “Molecular Ecology” will start. For one week we will generate molecular data to investigate patterns and factors influencing intraspecific genetic variation in benthic macroinvertebrates at the Forschungsinstituts Senckenberg in Gelnhausen. Subsequently, we will perform bioinformatic analyses in the second part of the module at University of Duisburg-Essen.
Study area will be the Rhein-Main-Observatorium.
We spent another day at the rivers Ruhr and Möhne to sample eDNA. Check out the video to see how we take samples and go for a drift dive in the Möhne!
We just published a short article in the Barcode Bulletin.
In the march issue (pages 10-12), Florian and Jan write about how different cryptic Deleatidium mayfly species from New Zealand show strongly different responses to anthropogenic stressors in the stream and the cosequences this has for ecosystem assessments.
The University of Duisburg-Essen (Campus Essen)
Centre for Water and Environmental Research (ZWU)
Aquatic Ecosystem Research Group (Leese-Lab) offers
1 PhD position (Part-time 55%; salary equivalent TV-L 13)
in Genetic Monitoring / Metabarcoding
(BMBF German Barcode of Life 2 subproject)
The group of Prof. Florian Leese is interested in developing new
molecular approaches to assess the ecological status of aquatic
ecosystems. Specifically, we develop and apply DNA metabarcoding
to monitor changes in stream communities under environmental
stressors. Furthermore, we utilize genome- wide markers and perform
transcriptional profiling to understand population and organismal
responses to multiple stressors. As part of a recently granted subproject
within the large collaborative German Barcode of Life Project (GBOL2,
funded by the Federal Ministry of Education and Research, BMBF),
we want to bring DNA metabarcoding of freshwater invertebrates to
the application stage. In cooperation with our collaborators at
the Zoological Research Museum Alexander Koenig (Bonn, Germany),
the candidate will collect samples, perform experiments, generate and
analyse next-generation sequencing data on whole communities (amplicon
sequencing). Further reading: Elbrecht & Leese, PLoS ONE 2015, DOI:

The successful candidate (f/m) will hold a Master in Biology, Chemistry or
Bioinformatics and has good experience in molecular lab work. Furthermore,
he/she has experience and strong interest in a programming or
scripting language (e.g. R, C, Python). Candidates will benefit from the
international and interdisciplinary research environment at the research
group, the GBOL2 project and the ZWU. Excellent high-throughput genomics
and bioinformatics equipment are available in the newly equipped labs.
The position will start as soon as possible initially for 2,5 years
(will be extended). Deadline: 29. February 2016
We are one of the youngest universities in Germany and think in terms
of possibilities, not limitations. In the heart of the Ruhrregion,
we develop ideas of the future at our 11 faculties. We are strong in
research and teaching, live diversity, support potential and are highly
committed to an educational equality that has earned this name.
The University Duisburg-Essen aims at promoting
the diversity of its members (see http://www.uni-

or equivalents according to ง 2 Abs. 3 SGB IX are encouraged.
The University Duisburg-Essen has been awarded for its effort to promote
gender equality with the “Total-E- Quality-Award”. It aims at increasing
the share of women in the scientific personnel and therefore explicitly
encourages women to apply. Women will be preferentially considered when
equally qualified according to the state equality law.
