Going down a rabbit hole of TX special elections on a Sunday morning was not what I expected, but it’s great news! Hope the wave continues in November…

Meriselviytymisen parantuminen voisi selittää kossien määrää, ja siihen taas voisi vaikuttaa se että vaelluspoikasille olisi ollut paremmin ravintoa. Silakoiden kunto on samaan aikaan kohentunut, ja niillä on samoja ravintokohteita.

The answer the people demand, to the question that somebody asks every 6-8 months
Europeans didn't learn about electric eels until after they learned about electricity. There are electric catfish in the Nile, and they were called thunder fish.
Native S. American peoples called electric eels something that translates to: the fish that takes away movement.

Sadly, the amazing research station where also this experiment was done was shut down a few days ago. Cheers to all the research ever done in Paltamo🥂!
In this new study that emerged from a great collaboration led by @morganefrapin.bsky.social and Ehsan Pashay Ahi, we dig into the molecular mechanisms of density-dependent effects in Atlantic salmon, specifically in their hypothalamus (a key site for endocrine regulation).

Personally it is exciting that this high risk, semi-natural experiment that started in 2019 and had its own flavour of challenges has provided these cool results. Kudos to @morganefrapin.bsky.social, @fishcongen.bsky.social and everyone else not on here 🤗
