Today I started out the morning talking about long-read sequencing and prediction models and ended the day by showing Masters students how to take eDNA samples from a river.
How cool is my job!? 🤓 Honestly if I told three-years-ago me what I do for a living he wouldn't have believed it 😃

3 weeks ago we reveived 30 tauros in #SaksfjedWilderness! Bred to fill out the missing ecological function of the aurochs (extinct in 1627). The replacement from NL was a major team effort and a process lasting c. 18 months.
Now science begins!

Hey everybody! @drjuliawester.bsky.social and I have a new paper!

We surveyed over 800 scientists, science communicators, and science educators who use social media.

Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑

Trump orders swathes of US forests to be cut down for timber President’s move to expand tree cutting across 280m acres evades rules to protect endangered species

Trump har nu underskrevet en præsidentiel bekendtgørelse, for at udvide skovfældning til 113 millioner hektar skov, der ellers har haft til formål at beskytte truede arter. Det er offentligt ejet skov direkte overleveret til tømmerindustriens motorsave.

Beavers build planned dams in protected landscape area, while local officials still seeking permits A beaver colony has gained overnight fame by building several dams in the Brdy protected landscape area, creating a natural wetland exactly where it was needed.

"Beavers always know best" 🦫💪

Land right disputes were delaying construciton of dam to protect downstream nature. Beavers moved in and built the dam in a couple of nights saving the government £1 million.
