🦐 Lepidurus as a Model for Biological Rhythms?
Vittorio Pasquali from Università del Salento, Italia presented his findings at @fblucph.bsky.social.
🔬 Highlights: #Lepidurus arcticus & couesii reveals strong patterns but #CircadianRhythms rhythm theories are challenged #Chronobiology
The ‘Seasons of Change’ project, working at Arctic Station, unites science, local knowledge and storytelling to amplify Arctic voices in Kalaallit Nunaat. Changes highlighted through lake-sediment cores. @helenmort.bsky.social @iestynbarr.bsky.social @kirstenseesternc.bsky.social Kathryn Adamson.
So glad for the collaboration with the lovely UK-team bridging #science and #poetry together.
Today we spotted two #Bowhead whales ((Balaena mysticetus) right outside the station at the sea ice front. The majestic Greenland right whale are special for #Disko_Bay and their singing is captured in real time by #hydrophones and broadcasted as part of the diskolive.com/the-animals#... project.
Just arrived in #Qeqertarsuag to work at @arcticstationucph.bsky.social for a short while. Fascination to watch the vanishing sea ice and the fragmented snow cover on land. #Spring is setting in it seems. Look forward to team up with the lovely station staff and scientists visiting the station.
Truly happy to be partner in one of the nine Arctic projects recently funded by #NordForsk. Our project: Arctic freshwater food systems - influence of warming winters and increased snow cover (FROST), will contribute to a sustainable development of the Arctic.

A fishy day at #UNIS for the limnology class. Guest teacher @grimsruddavidsen.bsky.social taught about ecology and behavior of #Arctic_charr. Fascinating how this 🐟 species coop with living in the #Arctic. Students got hands-on experience with modern fish tracking equipment. @limnology.bsky.social
Asked the UNIS #limnology_students to formulate #hypotheses about the effect of climate changes in Arctic lake food webs and to create doable in-situ experiments, that could provide answers. Creativity was high ranging from whole year mesocosms studies to fertilizing #lakes with goose droppings.
Wash and fine-sieve mud from the bottom of an arctic lake and you´ll find head capsules of #Chironomid mosquito🦟 larvae. We did so at the #UNIS freshwater course with Simon Belle from #SLU. Some specimen were truly old (~200 y) but 100% intact and are part of a climate story. #Paleo_limnology
Next paper of my Phd project published in @globalchangebio.bsky.social 🎉Read more to find out what makes #Arctic #diatoms arctic and why temperate diatoms could encounter significant barriers in their warming-driven poleward range-shifts.

In shades of green, rose, and blue, the northern lights dance in the sky above a rose-tinted, snowy landscape.
I wake to a dream, where the sky dances

Cool studies 🙂
Keep going with this interesting research.
There are challenges to do #freshwater sampling in -20oC through 95 cm ice, but this international class at #UNIS_Svalbard runs the whole operation smoothly. They collects under ice light profiles, water samples and plankton. Nothing competes learning by doing. @freshwaterscience.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

Congratulation 🎉 Great to see our study is featured. Link to the paper is in Babara's posts.
Today the Limnology-class at #UNIS_Svalbardwe had a very successful fieldtrip to the backland for sampling two mountain lakes. Air temp -22oC and water temp at 7 m depth +2oC. Ice thickness 1 m. Plankton in the nets? Oh - yes. @fblucph.bsky.social @jakobgiesler.bsky.social @rubensh.bsky.social
Daily life at #UNIS-Svalbard. Fieldwork is a prominent aspect of all courses offered at this university. Last Friday the entire limnology💦 class went on their first #winter-sampling event. Ice thickness was 83 cm and with a lot of snow on top. Higher education when it´s best @fblucph.bsky.social
Daily life at #UNIS-Svalbard. The return of sunbeams in #Longyearbyen is always celebrated on March 8 - whether the ☀️ appears or not. It did and the iconic miner in the middle of the town also go a sun crown.
Salmon fish folks; here's a 2 y post doc position with a great team of reseacher working in beautiful lanscapes. Highly recommended.
Daily life at #UNIS-Svalbard. Aurora borealis is mind blowing and happens often at 78oN.
Daily life at #UNIS-Svalbard. The short legged Svalbard reindeer (Rangifer tarandus platyrhynchus) walk the village with no fear of humans (until the hunting seasons starts).
This subspecies is only found on the Svalbard archipelago and is smaller than the Norwegian common reindeer.
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.
