#UniKonstanz limnologist David Schleheck reported yesterday on the research carried out as part of the DiMark project at the 30th-anniversary celebrations of the Friends of the Lake Constance Nature Museum. ➡️ t1p.de/zw7lt

World's predominant nitrogen fertilizer (urea) causes extreme eutrophication of surface waters in Canadian Prairies, China and USA when high urea use interacts with phosphorus-rich waters. New from @umanitoba.bsky.social & ureginalimnology.bsky.social at @naturewater.bsky.social rdcu.be/fdx2U

Trinkwassertalsperren reagieren deutlich auf die Klimaerwärmung. Eine Analyse von Langzeitdaten zeigt hochsignifikante Trends, seit 1995 im Mittel 1,4 Grad. Details in der aktuellen Ausgabe der WasserWirtschaft (free access): doi.org/10.1007/s351...

Happy to see our antifragility paper published! With @jonaswickman.bsky.social and @chrisklausmeier.bsky.social.

I still owe you some good environmental news from yesterday about #LakeConstance (thanks to MW for the tip) www.wochenblatt-news.de/region-boden...

Oh to be a little Tardigrade walking around a microscopic volvox algae colony. 🫧🐻🧪

1. `tinyplot` v0.6.1 is out on CRAN. This release contains mostly bug fixes and internal optimizations. grantmcdermott.com/tinyplot/NEW... Who knew that base #rstats plotting could be this easy and feature-rich? P.S. Check out @zeileis.org's nice slides here: www.zeileis.org/papers/Psych...

New study on patterns of diving behaviour of a #wels #catfish population that has recently increased significantly in a large, deep, cold-water peri-alpine lake - the Lake #Constance. link.springer.com/article/10.1...

Excited to see our Seasons paper published in L&O Letters this morning! In this @gleonetwork.bsky.social project we grappled with how to analyze seasons and seasonality in lakes over large spatial scales and amid global change doi.org/10.1002/lol2...

Fishing about 3,500 years ago 🎣 Bronze Age copper-alloy fishing hooks, from the pile dwelling settlement at Meersburg-Haltnau/Lake Constance. #Fish was a staple diet for pile dwellers - caught with hooks and lines, nets, harpoons, and fish traps. 📷 @almbawue.bsky.social 🏺 #archaeology

💧 World Water Day As the International Society of Limnology (SIL), we highlight the vital role of freshwater ecosystems, from microbes to lake and river networks, in sustaining life on Earth. Protecting water means protecting our shared future. #WorldWaterDay #Limnology #Freshwater

Just finished reading Gregor Mangolt's 1557 book "On the Nature and Traits of Fish — Especially Those Caught in Lake Constance". Fascinating early account including details on #parasites, #spawning #phenology #hybridisation, and spatial variability. #HistoryOfScience #LakeConstance

250 years ago studies of tintinnid ciliates began. Here are the guys who started it...New artcle about the pioneers is out in open access: ejournals.eu/en/journal/a...

Wow. Foraminifera! ROV pilots paused and carefully zoomed in to collect footage of these single-celled microorganisms, or protists, at 843 m during the #OBVI #LivingBioreactors expedition w/ @schmidtsciences.bsky.social offshore of Argentina. Read the full caption: youtube.com/shorts/Yv_ud...

Finally, OUP has sent a PDF to share. If interested DM me or send me an email

New DFG project #Zooptraits funded. We look forward to establish a data base and analyse 4 decades of morphological changes within a zooplankton community #ZooScan #Zooptraits #LakeConstance @uni-konstanz.de

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects. www.nature.com/articles/s44...

On the subject of penguins and madness, did you know that 9 King Penguins were released in 1936 in Arctic Norway by the Norwegian Nature Protection Society? At least a couple possibly survived until 1944. So for a brief period Polar Bears and penguins could in theory have met. #biologicalinvasions

Spiralling global temperatures (1850-2025) The last 3 years really jump out, rather like 2015-6 did when we first produced this graphic back then. Now, 2015-6 looks rather cool... More on the spiral: doi.org/10.1175/BAMS...

We've got ISSUES. Literally. We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do? arxiv.org/abs/2601.07563 A 🧵 1/n

A different kind of #LakeIce story: During the Second World War (winter 1939/1940), Swiss soldiers built a canal in the ice of Lower Lake Constance to prevent German soldiers (officially) and refugees (welcome side effect) from entering Switzerland. (Rosgarten Museum, Konstanz) #LakeConstance

Skating on #LakeIce

Still cold temperatures and near-shore ice cover at Lake Constance. But nothing compared to years with complete ice cover, such as 1963 (the last year with complete ice cover) or 1695, the latter depicted in a painting by X F Ziegler (Rosgartenmuseum, Constance). #LakeConstance #LakeIce
