hii everyone! I’m a postdoc at the university of british columbia and my research focuses on evaluating the impacts of climate change stressors in imperiled fish species ~ like this white sturgeon!! ~ to inform conservation practices. 🐟🐠🧪
madisonearhart.bsky.social
climate change is causing larger temperature variations BUT we know very little about how variable temperatures impact sensitive, developing fish

in this new study with @tblanchard.bsky.social & @trishschulte.bsky.social we found surprising impacts during development and after hatch!!

Atlantic killifish are robust little fish, but now @tblanchard.bsky.social & co reveal that fluctuating temperatures while the embryos are developing in the egg can have beneficial and damaging consequences

Excited to share another paper from work I did during my PhD with @trishschulte.bsky.social and @madisonearhart.bsky.social. We looked at how fish embryos respond differently to constant and fluctuating temperatures! 🐟

#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 🥵

Hi Matt! I would probably start with eDNA (environmental DNA) to confirm presence of sturgeon in the lake. Once confirmed then I would start a tagging/ telemetry study to investigate how they are using the habitat! Looking for white sturgeon living in alaskan habitats is on my research bucket list!☺️

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🧪👩🏻‍🔬🌎🌐

"...ferocious fire in recent years, fueled by climate change, has proved fatal to the trees that experts once thought were impervious to flame. An estimated 20% of the world’s mature giant sequoias have died in the last decade due to severe wildfires..."

I led a “punk science” activity for our incoming freshman biology majors at our orientation event. They made zines and fliers on any topic they chose. Here’s a sample:

In the coming weeks, the Trump regime plans to mobilize 1,700 National Guard troops to 19 states—most of which are Republican-controlled—to support ICE, their domestic terrorist organization.

They’re targeting these states:
AL, AR, FL, GA, ID, IN, IA, LA, NE, NV, NM, OH, SC, SD, TN, TX, UT, VA, WY

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 🫶🏼

Trump's new executive order about AI states that companies' models must not incorporate the idea that trans people exist as a concept. Seems bad.
The WHITE HOUSE
One of the most pervasive and destructive of these ideologies is so-called "diversity, equity, and inclusion" (DEI). In the Al context, DEl includes the suppression or distortion of factual information about race or sex; manipulation of racial or sexual representation in model outputs; incorporation of concepts like critical race theory, transgenderism, unconscious bias, intersectionality, and systemic racism; and discrimination on the basis of race or sex.
DEl displaces the commitment to truth in favor of preferred outcomes and, as recent history illustrates, poses an existential threat to reliable Al.

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social

We found that formerly common species have declined the fastest, on average.

Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

All of the conservation-related, science-based elements of the Forest Service are to be terminated or cut to the bone, while remaining functions to be centralized and narrowly focused on one goal -- timber production. This is an irreversible national disaster in the making.

hiiiii!! i work with the best dinosaur fish around, sturgeon & i would looooove to chat sturgies with you!!

check out #sturgeonsaturday for lots of my research related posts!! 🥹🥲

we caught this big mama while listening to pink pony club, so obviously #pinksturgieclub is now a thing

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

a sticker illustrating 3 women wearing an NSF lab coat, a NASA shirt, and NIH scrubs with the phrase girls just wanna have funds underneath. a portion of proceeds from this sticker will go directly to stand up for science to support funding initiatives  the same sticker in the wild on my very dented water bottle with the ocean in the background

UPDATE: Workers at FOUR of the most important US science agencies have now filed letters of dissent against their leadership.

After initially delaying their letter due to fears of retaliation, NSF workers have gone ahead anyway, and joined their colleagues at NIH, EPA, and NASA in speaking up.

Within the last 6 months, 402 attacks on science have been counted. “Attacks on science” include actions, statements, or decisions from an elected official in a federal agency that results in the censoring, manipulation or misinforming on science data/results/conclusions conducted w/in the govt.🧪
