And another one. 😁 My PhD thesis received the distinction of best dissertation at the agricultural faculty of the Humboldt University Berlin. I'm very honored by this prize, and yet again say thank you to all the people involved in my research over the years! You all rock! 😚

I had the great honor to be awarded with the dissertation award of the Baltic Sea Research Foundation for my PhD thesis on northern pike niche use and growth in coastal waters. I´m very happy about the prize, and thank the organizers for a wonderful ceremony in the Maritime Museum Stralsund. 🐟🎣🧪

One week of otolith drilling later... Working on a project investigating the distribution and ecology of non-commercial migratory fish, one part of the project aims at reconstructing marine movements. Our first idea was looking at otoliths! 🐟🐠🐡 🧪 Image: twaite shad (Alosa fallax) otolith

May I [once again] interest you in a little sturgeon break?

PhDone! Huge thanks to an amazing team, the Boddenpike gang, my inspiring supervisors & mentors, and everyone else involved in the project. Couldn´t have done this without any of you! Looking forward to many more exciting years of fishy research! 🧪🐟#PhDone #FishSci #Researcher

Next time someone tells you that the energy transition cannot be done remember: In 2012 almost 40% of UK electricity was coal. Since 1 October 2024 it is zero. This is the moment Britains last coal power plant shut down on 30 September - the end of 142 years of coal. HT @neso-energy.bsky.social

Little milestones which don´t mean a lot in the grand scheme of things, but I´m chuffed to have crossed 100 citations on my google scholar & RG profiles! Testimony to the fact there´s some people out there reading my stuff, thinking "well, that seems to make sense"! 😆🐟🧪

Hi #fishsky - calling all fans of the fish Lota lota or #burbot. What common names do you know for this species (in any language) and why is it called that? I have heard some very funny common names in US English and German for the species and would LOVE to know some more! #fishtaxonomy

Question for any ecology peeps that might read my tweets (blues? Do we have a new word for this by now? 😅): Do you know of any courses teaching species distribution modelling techniques (correlative/causative) that you can recommend? Grateful for any advice (baby pike pic for attention) 🙏🧪

Opt out tomorrow!

🎬 Lights, camera, action! 🌊 Last week, our new design pearls were in the spotlight. Part of our team was onboard our research vessel, testing its underwater visibility under the frequency of harbor porpoise clicks. Using an echosounder, we simulated these signals—and the results? Very promising! 🦑

Hey, higher ed leaders, this is what acting with courage looks like. Give it a try! We’ll support you.

The response of the science community to the last month is not about one statement or action. It's about all of us with our different frames. For Science's part, we are doing what we have always done and have no plans to change. My thoughts on what we can do. www.science.org/doi/10.1126/...

Congrats Erica Durante for publishing amazing research (+ your 4th PhD paper!). Erica developed methods to extract estrogen & progesterone from cephalopod beaks. Now we can get lifetime reproductive data from species we know little about! @aslo.org aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

Yes, more love for the "rough" fish! As soon as someone starts caring, that´s the first step! :)
