New IFishMan PhD. @otolitimo.bsky.social huge congratulations. A thesis on coastal pike ecology #proudsupervisor #pike #bodden
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.

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) 🙏🧪

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! 🦑
