New paper in Hydrobiologia! Lake Arresø shows how 50 yrs of nutrient management and sewage treatment cut Phosphorus inputs by 90% — yet eutrophication persists due to sediment resuspension. Real recovery will require reducing farm runoff further. 🔗 doi.org/10.1007/s107...

🌾 Big kickoff in Kenya for our Danida-funded project on climate-smart, low-emission rice! Partners from Kenya, Tanzania, Philippines, and DK aim to boost drought resilience & reduce methane. More than a project—it’s a shared commitment to a better future. #RiceResearch #ClimateSmart #Danida

Science at altitude! 🏔💧 Bhumika and Dean joined colleagues from Kathmandu Uni for an unforgettable research trip to Nepal. The Carlsberg-funded “Mustang” project, the goal is to better understand freshwater biodiversity, water quality & human impact in this beautiful and understudied landscape.

🌿 Our lab is now LEAF Gold certified! 🥇 Thanks to teamwork, smarter protocols, and great coordination from our technicians, we have taken major steps toward sustainability. Freshwater biology begins with fresh thinking 💧 #LEAFGold #UCPH_GreenLabs #LabSustainability

🚀 New & novel! Two of our BSc students are developing an innovative method to sample soil greenhouse gases using silicone tubing + Li-Cor analysis. It’s exciting to see real scientific advances made at the BSc level—this work is already generating great data! 🌱 #StudentResearch #SoilGHG

🎓🌿 New MSc! Yesterday, Rikke Frederiksen defended her thesis on macroinvertebrates in ponds on former farmland. We’re proud to send off a talented and great colleague and wish her all the best in her future endeavors. 🌟 #MScDefense #FreshwaterEcology #NewTalent

🌊 Bubbles matter! 💨 This new paper wraps up Jonas Stage Sø’s PhD work and brings new insights into methane emissions from lakes. The conclusion is that ebullition from lakes often dwarfs diffusive flux — especially at higher temperatures. link.springer.com/article/10.1... #methane #Ebullition

🌞 Beautiful day for lake sampling in Northern Zealand! Yesterday our MSc Freshwater Ecology students collected samples for next week’s lab on plankton & chlorophyll. Science, sunshine & teamwork! 🌊🧪 #FreshwaterEcology #Fieldwork #MSc #Ecology @janaisanta.bsky.social

We joined the Danish OIKOS Meeting 2025 at Aalborg University! 🎤 Talks by Andreas & Claudia 📌 Poster by Tobias on soil inoculation & land restoration Great to connect & share research! 🌿 #OIKOS2025 #Ecology #Conservation

🎧 New Podcast Episode! In the 10th episode of the ParAqua Podcast, Jana Isanta-Navarro joins host Joe Money to discuss her research on salinization in freshwater ecosystems and its impact on keystone species. 🌊🧬 paraqua-cost.eu/paraqua-podc... @janaisanta.bsky.social

Bravo, @sannemdt.bsky.social for a new study on microbial biofilm in Greenland streams across 3 regions. Highlights: 🟢 Cyanobacteria thrive even in the High Arctic 🌡️ P & water temperature are key drivers of biofilm growth ⛰️ Catchment slope & NO3 conc shape total biomass doi.org/10.1111/1758...

🎓🌿 Karina Yaldo has successfully defended her MSc thesis on conservation & biodiversity in Danish streams! 💧🌍 Ready to take her skills into the real world—congrats! 🎉 Employers, take note & give her a warm welcome! 👏 #MScDefense #FreshwaterConservation #NewTalent

After 5 mo inthernship in our lab, Tobias Guhr has completed his project on wheat flood tolerance and drafted his paper. His work on root responses to flooding & drought will provide new insights. Now back in Germany to finish his degree—best of luck from us, Tobias! 🌾🔬 #PlantScience #WheatResearch

Salmon fish folks; here's a 2 y post doc position with a great team of reseacher working in beautiful lanscapes. Highly recommended.

🌾Great news! Ole Pedersen's group has secured 10M DKK from Danida Fellowshop Centre to develop climate-resilient, low-emission rice for Africa! 🌍 Working with partners in Tanzania, Kenya & the Philippines, we’ll focus on sustainability & equity. 🚀 flooding.dk/blog/we-did-... #FoodSecurity #Equity

Winter conditions in Arctic lakes will be in focus for the next five weeks at the University in Svalbard #UNIS-Svalbard during the annual MsC and PhD course. I look forward to meet a fully booked course with super-motivated students in few days. www.unis.no/courses/ab-8...

Gave an invited lecture for the Danish University pedagogy network on how we at Dept of Biology www1.bio.ku.dk/english/ create research-based teaching. Our annual Arctic Biology Field course kurser.ku.dk/course/nbik1... in Greenland for master students takes this approach very seriously.
