Congrats to Martina Weiss for the successful defence of her PhD thesis entitled “Investigating patterns and processes underlying cryptic diversity and small-scale population structure in hololimnic freshwater species”. The project was part of the “GeneStream” project funded by the Kurt Eberhard Bode Foundation.

If you’re interested please join a discussion on the state and future of the oceans on Monday 15th of May at Unperfekthaus Essen.
We’re happy to welcome Darina Siposova from the Slovak Academy of Sciences to our group. Darina has been awarded a DBU stipendship and joins our GBOL project on metabarcoding / eDNA anayses of rivers. Furthermore, Darina studies the population genetic structure of aquatic beetles in the high Tatra as part of her PhD thesis.

Yesterday, a new publication by Vasco und Florian entitled “Validation and Development of COI Metabarcoding Primers for Freshwater Macroinvertebrate Bioassessment“has been published in Frontiers in Environmental Science (Link). In the study we demonstrate problems with several of the currently available metabarcoding primers and tested four newly developed COI primers targeting aquatic macroinvertebrates. Our analyses show that the new primers (BF/BR) are highly suitable and amplify very equally the analysed taxa. Most importantly, however, our study shows how important careful design and validation of primers for a certain region, habitat or target taxon group is. With growing data bases there is still much potential for future improvement.
Bianca Peinert from our group has just been awarded the Prize of the 50th Essen Water Quality and Waste Management conference. She received the highly competitive price for her innovative Master Thesis on “DNA-based aquatic biomonitoring“, which was part of the GeneStream-Project (Bode Foundation). Main supervisors of the thesis were Vasco Elbrecht and Arne Beermann, PhD students at leeselab. The award of 2000 Euros was shared this year by two winners.

Since November 2016, Florian leads the large EU COST Action Network DNAqua-Net. As the Grant Manager of the Action, Alexander is the responsible coordinator of the network which already now encompasses 300 researchers, end user, managers & regulators as well as industry partners from 42 nations.
The aim of the COST Action DNAqua-Net is to explore the potential of novel DNA-based methods for bioassessment of aquatic ecosystems (lakes, rivers, oceans, groundwater) and to suggest standardised application strategies. These can only be successful in large-scale monitoring programs, such as the EU Water Framework Directive, if researchers within the scientific community agree on clear standards and work together with partners from the environmental regulators and industry partners.
Just now, from March 6th until 9th, we have hosted the Kick-Off conference of DNAqua-Net in Essen. 172 participants from 37 nations met at the Campus of our University to discuss in a highly constructive atmosphere chances and limits of the novel techniques. Some impression from the conference as well as the preceding Management Committee meeting can be found here.
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.
