It is our last day of field work for 2026 for the ZooPUFA project @uniofjyvaskyla.bsky.social We have been taking water samples, productivity incubations, phyto/zooplankton samples, and perch tissue samples from 25 lakes across the southern half of Finland!

#ZooPUFA update here at @uniofjyvaskyla.bsky.social, our perch are growing up fast! 🐟 They are now split into experiment tanks, being fed live artemia (commonly called sea monkeys) 🦐 with different fatty acid profiles as a pilot study to see how LC-PUFA sysnthesis expresses isotopically!

Two small perch, just starting to show stripes, are resting on the bottom of the tank

New paper alert 🚨 led by the awesome @nadescha.bsky.social examining Antarctic food web recovery post disturbance by combining food web models with stable isotopes! Check it out in Marine Environmental Research at www.sciencedirect.com/science/arti...

Graphical abstract of paper showing how frequency of disturbance (ice berg scouring) correlates with food web metrics and changes in structure during recovery period.

It is all go here in the #ZooPUFA project here at @uniofjyvaskyla.bsky.social now that spring has hit Finland so soon! The early ice melt meant early spawning for perch which means i got these cuties arriving a bit earlier than planned! 😅

The other night I managed to snap the beautiful aurora or "revontulet" in finnish. The literal translation means "fox's fire" as it was believed that they came from the reflection of moon and starlight on glistening snow that is cast into the sky by the tail of a dashing fox. Enjoy 😀

Green swirling aurora borealis reflected in a still lake, with twinkling street lights on the far shore.

New paper alert! Was great to contribute to work of @mikealthaus.bsky.social and colleagues demonstrating how re-entering the marine environmental led to the evolutionary loss of the high concentration "stress" signalling sodium ion channel isoform in mammals! nature.com/articles/s42003-025-08436-7

Graphical abstract with marine mammals on the left where the alpha sodium ion channel isoform is closed under high salt concentrations. On the right are terrestrial mammals where there is an additional ion channel isoform, the delta isoform, that is open under high salt concentrations. This is hypothesised to function as a potential “stress” protein for monitoring high salt levels that has secondarily been lost in marine mammals.
