Professor at University of Duisburg-Essen 🇪🇺🇩🇪 tweeting mostly about the work we do in our Aquatic Ecosystem Research Group. A lot of DNA / eDNA & popgen stuff on streams & automated biodiversity monitoring approaches.
We’ve kicked off the #eDNA #Metabarcoding workshop with @leeselab.bsky.social , @dominikbuchner.bsky.social , @tillmacher.bsky.social, and a highly international group of attendees working on a variety of exciting projects.
Looking forward to a fun and productive week of learning! 🎉
🎉Our 2025 Editor's Choice award goes to: "Surface swabs outperform most traditional honeybee (Apis mellifera) hive samples for recovery of eDNA and eRNA" by Erin Hill, Liz Milla, Francisco Encinas-Viso, James O'Dwyer, Ben Gooden, Mariana Hopper, John Roberts.

New study on the spatial dimension of multiple stressors. Gemma Burgazzi (iDiv) did a great job in running this mesocosm experiment. Effects of single stressors cascaded along the network, with stronger downstream effects. Thanks to all contributors! @leeselab.bsky.social doi.org/10.1002/ecog...

In massive #collaborative #effort, we assembled published & unpublished #fish 🐟 #eDNA 🧬 metabarcoding datasets, covering ~2000 sampling sites/>100 river systems globally. 🐟 🐠 🐡 🌐 🌍
Now results out in 2 #parallel #preprints @biorxiv-ecology.bsky.social

Every year a highlight & intense period: Our molecular ecology module! We train advanced Master students on how to apply DNA & #eDNA #metabarcoding to assess riverine #biodiversity.
Long #Day1 today as we sampled until 19:30. Motivation: 10/10. Tomorrow: to the lab! @unidue.bsky.social @sgn.one
New database on thermal tolerance on freshwater invertebrates and fish - major effort by Helena Bayat and many collaborators. Freely available here: www.nature.com/articles/s41...

15th Water Research Horizon Conference of the #WaterScienceAlliance will take place @ruhr-uni-bochum.de 29/30 September. Focus: #urban water bodies / #watercycle
Time for inter- & transdisciplinary discussions. Also: Award ceremony of new junior #research group

By comparing three strategies for local bioassessments in streams using environmental DNA and RNA metabarcoding, researchers find the most effective strategy is to briefly incubate collected organisms in water then analyse the enriched eDNA.

Wahl zum Wissensbuch des Jahres 2025
Ich freue mich sehr, dass unser Buch „Von Angesicht zu Angesicht“ dabei ist!
Ihr könnt uns sowie unsere Arbeit, mit der wir für biologische Vielfalt begeistern, mit eurer Stimme in der Kategorie „Ästhetik“ unterstützen: www.konradin-service.de/umfrage/inde...
It’s happening again! Our @crc-resist.bsky.social team from @unidue.bsky.social is in Hesse to prepare the next large #ExStream experiment. Stay tuned.

We’re happy to announce Dr. Lennard Stach!! 🥳🥳 Well done Lennard for a brilliant defense and thesis!! We will miss you!
Finally, thank you @leeselab.bsky.social for sitting in the thesis committee! 🫶
🎉 We’re thrilled to kick off the Eukaryotic "eDNA" Metabarcoding workshop with @leeselab.bsky.social @dominikbuchner.bsky.social , @tillmacher.bsky.social , @shump.bsky.social & an amazing group of participants joining us from across the globe—from Australia to Peru, from USA & Canada to Europe! 🌍🧬💻

Our team @unidue.bsky.social turned 🔟 today & I found myself in a spontaneous celebration event.
Really happy & grateful to work here with such a great bunch of talented & nice people - connected to our collaborators around the 🌎. Life could be worse. Weiter geht‘s. ☀️Maybe more lab work next 🔟 ?
Very good to see our @pensoft.net journal @mbmg.pensoft.net continues to receive good CiteScores and also now the first #ImpactFactor with a good value of 3.1 ☀️
While I personally don’t care much about these metrics I know they are really relevant for many institutions. Thus: very happy about this!
🙏 And just as an addition: don‘t use these primers for bulk sample metabarcoding. There others are ways better (we recommend fwhF2/fwhR2n as a good solution; further solutions like BF2/BR3 or mlCOI with dgHCO exist)

🌍 Europe is facing an exceptionally dry spring in 2025: 37 out of 38 countries covered by the @EEA have been hit by drought.
To help track this growing threat, we’ve launched a new interactive drought map 🗺️— updated monthly & based on near real-time data: water.europa.eu/freshwater/e...
Great News: Our book Aquatic Parasitology: Ecological and Environmental Concepts and Implications of Marine and Freshwater Parasites has been published online open access! link.springer.com/book/10.1007... @nicojsmit.bsky.social @unidue.bsky.social

FAIR #eDNA data and transparent workflows are essential. Harmonisation should come after standardisation. International collaboration and partnership will drive progress #UKDNAWG25

Different labs can produce vastly different results which leads to ‘eDNA doesn’t work’ - ring and proficiency testing is key. Establishing minimum standards (e.g. sequencing depth) and metadata reporting is crucial. Stringency of standards will vary by taxonomic group #UKDNAWG25
