Blir gäddor i fredningsområden mindre skygga, och hur påverkar detta isf ekosystemet i grunda havsvikar? Detta studerar doktorand Emil Kraft och masterstudent Alexander nu i sommar, vilket uppmärksammades av @svtnyheter.bsky.social : www.svt.se/nyheter/loka...

I wish more highly successful researchers would do what @lovedalen.bsky.social did here: reveal how much effort, and repeated rejection, that typically precedes each success in science. Never give up.
At the end of his #ESEB2025 plenary on deep-time palaeogenomes, Love Dalén shared his history of trying to obtain a big grant for his work. It eventually worked out!

Vad händer med upptag och utsläpp av växthusgaser när havens ekosystem störs? Detta är en fråga vi i sommar studerat på Askölaboratoriet, vilket nu uppmärksammats i bl.a. i Rapport: @svtnyheter.bsky.social : www.svt.se/nyheter/loka...

#Seaweed farming has many potential benefits, but scaling these farms cannot be at the expense of other habitats (e.g. #seagrass) that support people! In our short letter, me, @eklof.bsky.social, @zosterar.bsky.social & others discuss why caution is needed.

One of the most important things you can do today is your science. Knowing calculus/physics/genetics/chemistry etc. makes you rare and the world will need you to rebuild tomorrow. Practice your skills and pass them on. Keep the flame alive.

Atlantic herring is one of the most abundant fishes in the world. In two new studies, we show that some herring in the Baltic Sea have become fish eaters. These piscivorous herring are genetically unique, grow fast, and play an important role in regulating stickleback populations.

In the coastal areas of the Baltic Sea, unusually large herring are sometimes caught, which has long raised questions. Are these large herring a separate population, or are they individuals that ha...
