An interesting paper for all friends of Daphnia, including researchers from the German Limnological Society @dgl-ev.bsky.social
sil-limnology.bsky.social SIL | International Society of Limnology @sil-limnology.bsky.social · Oct 10
🌞❄️ Article of the Day:
High-mountain Daphnid from the tropical Andes face a double threat as warming and UV radiation together reduce survival despite their natural pigmentation defenses. This study shows that combined stressors, not single factors, shape the fate of these cold-adapted zooplankton.

Fascinating an motivating plenary talk from @florianaltermatt.bsky.social at #DGL2025. He made a strong plea for rethinking the way we use eDNA to monitor aquatic biodiversity. Inspired me to read more about his research.

User! Conference 2026 will take place in Warsaw, Poland 🇵🇱

Provisional dates: Dates Monday 6th July to Thu 9th July 2026.

Hope to see you all there.

Alt text: A vibrant, stylized nighttime cityscape symbolizing Warsaw, Poland, host of the UseR! 2026 Conference. A glowing river winds through the city, bordered by illuminated buildings that blend modern skyscrapers with traditional European architecture. The deep blue sky sparkles with stars and celestial bodies, and a large moon-like orb at the center displays a bold letter "R"—a nod to the R programming language, widely used for statistical computing, data analysis, and visualization. The image’s rich blues and warm yellows evoke both innovation and cultural heritage. The UseR! Conference series is the premier international gathering for R users and developers, fostering collaboration, sharing cutting-edge research, and promoting open-source tools. This artistic depiction captures the excitement and creativity of the global R community coming together in Warsaw for learning, networking, and advancing data science.
