How does salinity affect growth? @fryderheim.bsky.social & I developed a model to describe this, and he's parameterised it for >100 species. We can now model how salinity changes should affect population & community dynamics! Check out his poster on Monday afternoon at #OSM26

New preprint out! 🌊🧪🌎 🧮➕📏 Temperature preferences estimated from lab experiments and species distribution models agree reasonably well! This increases my confidence in our ability to forecast range shifts. www.biorxiv.org/content/10.6... 1/n

Next week at #OSM26, I’ll be sharing our (w/ @mridulkthomas.bsky.social) work on a new approach for describing how phytoplankton growth responds to salinity, using a large set of experiments to estimate key traits across species. See you at poster OB14B-0481 on Monday!

First time doing field work in 8 years 😵‍💫 Local newspaper reported lots of dead fish floating around Lomma harbor. Lack of oxygen is the likely explanation, but is it the cold weather/stagnant water or perhaps something microscopic? Looking forward to analyzing samples next week in the lab.

Phytoplankton empiricists: anyone have a good protocol (or reference) for treating fungal contamination in stock cultures without re-isolating? 2026 continues bringing all the icks...

Happy to see our analysis on scaling up temperature x nutrient interactions from populations to communities published in Ecological Monographs @esajournals.bsky.social! 📈

Hey #microbialsky - anyone looking for a good PhD student this cycle? Ugrad from my lab is looking but no luck with the PIs she has contacted (no funding, no response). She worked in my lab for 1.5 years, now is a research tech at the FWC research institute. Excellent at the bench & super smart!

In our study on Prymnesium parvum, we found that low salinity inhibits prymnesin production, while slower growth leads to higher cellular toxin quotas. Intraspecific differences may help explain bloom success across environments. #openaccess in Harmful Algae www.sciencedirect.com/science/arti...

Our latest paper on predator-induced defense is now out in Harmful Algae. We show that Pseudo-nitzschia seriata induced to produce more domoic acid grow slower and, because of increased cellular N, produce less cells as nutrients become depleted. www.sciencedirect.com/science/arti...

We usually think of photosynthetic bacteria as the main N2 fixers in the world's oceans . Using a mechanistic model we estimate that heterotrophic bacteria are responsible for 10% of the global N2 fixation. And it also occurs temperate waters. www.science.org/doi/10.1126/...

Squid die when they reproduce. We estimate that sinking squid carcasses locks away 11-12 Mt carbon/year in the deep oceans. Increasing squid fisheries interrupts this sequestration and sends it to our dinner plates - where it is respired to the atmosphere. www.sciencedirect.com/science/arti...
