New paper out! We studied how nutrient enrichment and catchment degradation affect fish communities in tropical Myanmar streams — and found surprisingly weak responses, suggesting fish are poor bio-indicators in these systems. onlinelibrary.wiley.com/doi/10.1111/...

🚨Open call to all our early-career friends involved in collaborative/ECR-lead projects to join this interesting session at the upcoming ASLO-SIL meeting in Montreal 2026! Hope to see many of you there 💦💙

The coming layoffs will inevitably affect the quality of our teaching, and we deeply regret the impact this will have on our students. The Study Board for Biological Sciences has articulated their concerns clearly in this opinion piece from UNIavisen. uniavisen.dk/en/the-stude...

The employees at the Dept. of Biology have decided to cancel the the planned meeting with the Rector. The cancellation reflects the growing concern among staff at SCIENCE about the announced layoffs and the lack of genuine dialogue with university leadership. uniavisen.dk/biologi-boyk...
