#sturgeonsaturday 🧪👩🏻‍🔬🌎🌐 the last 2 years i’ve been investigating why these giant fish are dying across BC and i’ve started to identify the stressors that could be driving mortality!! if you want to learn more, check out this video: tinyurl.com/4m4xxrkh tldr; it’s getting hot out here yall 🥵

in the field for #sturgeonsaturday ive spent the last 2 yrs investigating what is killing BC white sturgeon unfortunately, these deaths continue & we’ve had over 50 adult sturgeon die in the fraser river in the last ~6 weeks every fish i sample is another step closer to solving the mystery🧪👩🏻‍🔬🌎🌐

hiiiii i’ve been mia for a bit but im back with looooots of field work photos - we’re doing some really cool sturgeon science this summer!! here i am, in my element holding my fave creature, trying to save the dinosaurs one sturgie at a time 🫶🏼 #sturgeonsaturday everyday 🧪👩🏻‍🔬🐟🌎🌐

out of pure rage for the obliteration of science funding i made a sticker cuts are disproportionately impacting EC scientists & women~particularly Black women and women of color 25% of proceeds will go to @standupforscience.bsky.social to keep fighting! 🧪👩🏻‍🔬🌎 plz share widely tinyurl.com/5n7kjbwt

i was recently interviewed by @csz-sczofficial.bsky.social about my phd, science, art, really all things 👩🏻‍🔬🧪🐠🌎 still over the moon i got this award, sometimes i am still reminding myself that i did a phd 🥲 check it out! 👇🏼 blog.csz-scz.ca/2025/06/30/s...

the horrors persist, but so do closeups of baby sturgeon everyone say hi to the cutest fish alive!! #sturgeonsaturday 🧪👩🏻‍🔬🌎🌐

everyone! look at this baby sturgeon! literally the cutest creature to ever exist but unfortunately we have less and less of them in BC with juvenile recruitment issues it’s always so awesome to find lil untagged bbs - this trip 5/14 of our sturgeon were untagged! #sturgeonsaturday everyday🧪👩🏻‍🔬🌎🌐

we’re so back baby!! an excellent start to the sturgeon field season today :) here’s a 7ft sturgeon being released #sturgeonsaturday everyday 🧪👩🏻‍🔬🌎🌐🦑

have yall ever seen a 1day old sturgeon?? right out of the egg? WELL NOW YOU HAVE barely any eyes, no gills, just vibes & yes that tube is their beating heart 💓 (microscope vid so plz forgive the lighting) #sturgeonsaturday everyday 🧪👩🏻‍🔬🌎 (p.s. get some sturgie stickers tinyurl.com/3dd65s4p)

it’s #sturgeonsaturday👩🏻‍🔬🌎🧪🌐 did you know there are 8 sturgeon species in N. America? spread across the continent, they are found in rivers, estuaries & the sea i made stickers for each sturgie that lives here, so you can always have your fave fish with you www.madisonearhart.com/category/sti...

its #sturgeonsaturday! did you know that some sturgeon make very long spawning migrations? Similar to salmon, some species of sturgeon migrate hundreds of miles from the sea to rivers to spawn after navigating a long journey once they are in freshwater they will release millions of eggs! 🧪👩🏻‍🔬🌎🌐

first market of the summer means lilacs!! 🌞

it’s #sturgeonsaturday 🧪🌎👩🏻‍🔬🎨 today i want to highlight the illustrations ive made for sturgie sci comm & publications im super passionate about visual storytelling - below is my portfolio, check it out :) need help with a graphical abstract? exp design? a talk? hit me up! madisonearhart.com

yesterday i was given an award for the outstanding phd thesis of the year from @csz-sczofficial.bsky.social i gave a talk about my phd, full of science & art i focused on how fish cope with environmental change & the importance of art in science 🧪🌎👩🏻‍🔬🌐🎨 here is the full talk: tinyurl.com/257jkbmh

This is a fascinating study on fishing altering fish migratory patterns. It’s management implications are important. I’ve argued that Limit Reference Points also need to consider the ecological role of the fished stock. This is an example of why that matters. www.nature.com/articles/s41...

#sturgeonsaturday! 🧪👩🏻‍🔬🌎🌐 not only are the sturgeon in the Nechako river facing no babies, the last few years there have been unexplained mortality events in the large adults 😩 (typically at the end of summer) Im investigating what may be causing these mortalities and the role of climate warming 🧐

here’s the paper that investigated the otter predation on lil sturgies - when going out to find tags researchers were lead to otter latrines, where they had pooped out sturgeon tags after eating them 😩 cdnsciencepub.com/doi/abs/10.1...

#sturgeonsaturday all week! 🧪👩🏻‍🔬🌐🌎 because there are no larvae surviving in the Nechako river, the mandated hatchery releases 2 y.o. sturgeon to increase the population it took trial & error in deciding what size to release sturgeon, turns out small sturgeon are otter snacks 🦦 3 y.o. sturgie 👇🏼

New @science.org Exposomics. We're not doing nearly enough to understand and mitigate our toxic environmental exposures. A very insightful perspective www.science.org/doi/10.1126/...

happy #earthday! we’re gonna do #sturgeonsaturday everyday this week! I’m in northern BC on the Nechako river, with a super endangered population of white sturgeon with no babies seen in 70 years! 😭 I’m here to assess stressors in this population while we fish for hatchery broodstock 🧪🌎🌐👩🏻‍🔬

#sturgeonsaturday (all week!!) you may be thinking wow what do you mean no baby Nechak sturgeon in 70 years? i’m gonna describe some of the problems the Nechako sturgeon face and what is being done to solve these problems so follow along (if you love sturgeon and really who doesn’t)!! 🧪👩🏻‍🔬🌐🌎

this #sturgeonsaturday looks a little different!! on the way to a sturgeon gala to meet with some incredible people who are all working to save white sturgeon 🫶🏼 doing science together with different rights and shareholders gives us a chance to make lasting conservation changes! 🧪👩🏻‍🔬🌎🌐

#sturgeonsaturday on a thursday 😱 whaaaaat!! 🧪🌎👩🏻‍🔬🦑 new paper and illustration 🥲 we investigated what happens to the gill transcriptome during development in lake sturgeon turns out bb sturgeon are using epigenetics (histone mods & dna methylation) and cell death (apoptosis) to make grown up gills

New lake sturgeon work out investigating transcriptional shifts in the gill during early development mRNA changes associated with histone modifications, DNA methylation, and apoptosis were conserved across both populations, as well as population-specific processes 🧪🌎🌐🐠 tinyurl.com/bdekwzed

Thrilled to be selected as a 2025 Liber Ero fellow to continue my research investigating the cumulative stressors which contribute to early marine mortality in juvenile Pacific salmon! 🧪🌎🌐🐠

did you know that it can take white sturgeon over 20 years to spawn?? this is one of the reasons sturgeon populations are threatened ~ it takes longer for them to bounce back! 🧪🌎🌐👩🏻‍🔬 #sturgeonsaturday

We made the cover www.nature.com/articles/s41...

hiiii come chat with me about how to make stellar presentations to tell your science stories 🥲🫶🏼 🧪🌐🌎👩🏻‍🔬

it’s not everyday i can release a sturgie with one hand! 🧪👩🏻‍🔬🌎🌐 these small sturgeon may be tiny (& adorable) but they are also feisty & covered in super sharp scutes (like small serrated knives) these scutes protect small sturgeon from predators so they can live to be big & old! #sturgeonsaturday

heeellpp!! does anyone have good resources or examples of turning an academic CV into an NGO resume?? 🧪👩🏻‍🔬🌎 Any recommendations are appreciated!! 🥲🙏🏼

Quite an essay on the basis of cancer entitled "The End of the Genetic Paradigm of Cancer" @plosbiology.org arguing against the primacy of somatic mutations (traditional model) and cells, invoking gene regulatory networks and tissue journals.plos.org/plosbiology/...

this #sturgeonsaturday is brought to you by the cutest creature in existence~ a tiny white sturgeon yesterday with the help of citizen scientists we tagged & took minimally invasive samples from a bunch of lil sturgies to assess population stressors ~ so great to see these untagged juveniles! 🧪🌎👩🏻‍🔬🌐

Climate change threatens river ecosystems, underlining the need for water management strategies to protect native species. This study evaluates the effects of climate change on threatened white sturgeon, and suggests approaches for managing these impacts. Read it here: doi.org/10.1093/conp...

new sturgie research!!! 🧪🌎👩🏻‍🔬🐠 here we combined physiological data with climate change hydro models to assess the current and future impacts of warming rivers on young life stages of sturgeon check out the paper below 👇🏼

1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social. www.nature.com/articles/s41...

i haven’t done #sturgeonsaturday the past few weeks bc of *everything* but its #internationalwomensday and we should recognize & celebrate incredible women in science! tell us about your research!👩🏻‍🔬 im a conservation physiologist researching the impacts of climate stressors on white sturgeon 🧪🌎

How vulnerable are amphibians to global warming? 🐸🌡️ Check out the amazing research by @patricepottier.bsky.social et al. 👇 www.nature.com/articles/s41...

Another paper from my PhD where we looked at the short and long term effects of raising embryos at two different temperatures 🐟 Interestingly hypoxia tolerance but not thermal tolerance was shown to be altered in juveniles.

science (sturgie) photos!! 🧪👩🏻‍🔬🌎🌐 🫶🏼

Understanding responses to co-occuring stressors is especially important for at-risk species. Learn more in this new study: Prior thermal acclimation gives White Sturgeon a fin up dealing with low oxygen. 🐟 Read it here: https://buff.ly/41YbKd3

Check out our new study looking at how white sturgeon deal with warming and low oxygen! 🌡️🫧 Interestingly, the order in which these stressors are experienced and whether exposures are acute or chronic may have important effects on their responses

How do early developmental conditions affect stressor resilience in fish later in life? We investigated this in a new paper lead by @tblanchard.bsky.social! 🧪👩🏻‍🔬🌎🌐🦑 We found that in killifish, sub-optimal developmental temps had lasting negative impacts on hypoxia tolerance later in life 👇🏼

for #sturgeonsaturday i want to highlight the crucial research done by many scientists across north america in conserving & saving 8 sturgeon species 🧪🌎👩🏻‍🔬🌐🦑🐠 right now, conservation science is an act of resistance, and we must fight to continue to save our animals that cannot save themselves 1/
