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.

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!

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. Details: September 23rd 16:00 CEST ; 14:00 UTC Description: Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.
@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.
We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

📣 We are excited to share our latest paper, led by @taliashaler.bsky.social! We explore the transcriptional basis of #microalgae resistance to #viral_infection and identified a core group of resistance-related genes. >>

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells?

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.

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.

The footage of bottom trawling alone makes the film worth watching. Let’s hope this destructive method of killing ocean creatures is outlawed soon.
