New paper out today on Sea Star Wasting in Proc B @RSocPublishing – Longitudinal gene expression and microbiome data: visibly healthy stars = active immune and collagen systems + stable microbiome. Wasting stars = hypoxia + turnover to anaerobic microbes. royalsocietypublishing.org/d…
Take home: The tipping point between health and disease is likely shaped by host condition, low oxygen conditions, and microbial dysbiosis. These results are also supported by our field-sampled naïve, exposed, and wasting sunflower stars in Alaska: frontiersin.org/articles/10.…
Beautiful and inspiring talk and visit with @chengsbrian. From atmospheric rivers, to oyster drills, to MPAs! Thanks for visiting @BiologyUVM!
New paper @FrontMarineSci – The microbiomes of Naïve, Exposed, and Wasting sunflower stars sampled in the wild in Alaska as the disease spread north implicate Vibrio and low oxygen conditions. Amazing collaboration among @QuestUvm trainees and AKDF&G!

Today is a big news day for ocean science and economics @UBC. See below. @ubcSPPGA @SSHRC_CRSH @KillamTrusts @TylerPrize @envpriz @pewenvironment @oceana @OceanCanada @SolvingFCB @SeaAroundUs
Two @UBC ocean fisheries experts – marine biologist Dr. Daniel Pauly (@SeaAroundUs) and fisheries economist Dr. Rashid Sumaila (@DrRashidSumaila) — have been awarded the 2023 Tyler Prize for Environmental Achievement. @TylerPrize

#SeaUrchin larvae don’t grow or survive well when exposed to compounds that leach from #plastics into the ocean. Surprise - the most detrimental effects were at intermediate doses! Project started by a curious undergrad and finished by Master @EmilyShore8! sciencedirect.com/science/ar…
New paper! 25 gens of exptl evol of copepods - ambient, ocean acidification, warming, and combined -> warming is the strongest selective pressure, but the combination results in a unique synergistic response pnas.org/doi/10.1073/pnas.22…

See our cartoon abstract!
Big picture take home: 1+1 ≠ 2 when it comes to global change adaptation!
Amazing collaborators!:

Congrats, Dr. Ashlock! In one week, @AshlockLauren defended their dissertation and lined up a postdoc! Lauren’s work explored the effects of pop, life history, and enviro history on copepod temp and salinity tolerance. The oceans thank you, Dr. Ashlock! @QuestUvm @BiologyUVM

New paper @NatureComms! We show that rapid adaptation of #copepods to #GlobalChange leads to a loss of plasticity – costs revealed even w/ return to benign conditions nature.com/articles/s41467-0…

Big picture: Nature is both resilient and vulnerable. We need to make and encourage Earth-friendly choices to protect and preserve the beauty and complexity that exists on this world.
For a fun and accessible press release: go.uvm.edu/copepod
25 generations of experimental evolution in copepods + genomics + beautiful analyses and visualizations show that adaptation to ocean warming and acidification is synergistic rather than additive. Check out our new preprint just up!

We measured fitness across 25 generations of experimental evolution to find “Rapid, but limited, zooplankton adaptation to simultaneous warming and acidification” Out this week @NatureClimate with @planktonomics and @reidbrennan! #UVMResearch #copepods

Awesome new synthesis of global patterns in copepod thermal tolerance by @Matt_Sasaki just out! What a useful product of the pandemic! Thanks, Matt!

#Copepods have slower pop. growth and slower sinking poop when they eat #microplastics. This may be bad news for the oceanic food chain and carbon settling. Emily Shore’s MS thesis @BiologyUVM just out in #Environmental #Pollution! Free PDF til Jul 23! authors.elsevier.com/c/1dB29…

This UVM’s “Beyond Brave Spaces” conversation: QuEST director @mpespeni , UVM President @SVGarimella , Dr. Linda Schadler & Marie Worsham Banks discuss and address inclusive solutions to the barriers BIPOC & womxn face in STEM youtube.com/watch?v=2m6KYm_y…
And said so well! Thank you, @big_data_kane !
