It's World Fish Migration Day, a perfect time to learn more about how more than 1,000 fish species around the world migrate to, from or within rivers to fulfill other critical life cycle needs. See how we're reconnecting rivers with those who depend on it most, here: https://nature.ly/4dBiDF9

Turns out, if you stop tearing up the seabed, wildlife thrives: ten years after banning bottom trawl fishing, there are 3 times the number of sea creatures + double the number of species in the South Arran MPA, Scotland, than there were before the ban 👏🦪🐟 share.google/2M5WqP3CXwSH...

A little friend I met today.

Our new paper is out! We developed a multispecies OpenArray™ chip to study cellular stress response in Acipenser species. The chip was used to measure the effects of acute thermal stress on Atlantic, lake, and shortnose sturgeon. onlinelibrary.wiley.com/doi/epdf/10....

New research detailing high throughput sturgeon molecular tools developed by @biologyhossein.bsky.social is now live! Here we developed and tested assays across sturgeon species to evaluate impacts across a variety of pathways induced by thermal stress 🧪🌎🌐🐟 onlinelibrary.wiley.com/doi/epdf/10....

Please enjoy baby Alligator Gars feeding on brine shrimp (Artemia), set to a Bluey instrumental 🙂 🐟🧪gars are planktivorous at this stage (20 mm, 12 days post-hatch), but will soon switch to eating insects and fish! They’re also already breathing air!

this graduation speech moment is notable, and her amazed shock at having failed to read the room feels instructive. when you're inside the bubble, you think everybody else is. but everybody isn't.

super super important read!! DFO cuts are directly gutting pacific salmon research and conservation by cutting a CRUCIAL lab & associated members responsible for identifying the stressors and pathogens leading to population decline!!! 🧪👩🏻‍🔬🌐🌎

I'll add only that if you're not already aware, Dr. @wbuggiii.bsky.social has been working with this lab. I'm not affiliated nor a genomics expert but the work they do is the *keystone* to resource management, restoration (that is me), & conservation per founder & now emeritus lead Dr. Kristi Miller

Ongoing DFO cuts to the Genomics Program and across the organization further compromise the capacity to conduct critical research evaluating the impacts of cumulative stressors and pathogens on salmon survival and to aid in the conservation of imperiled stocks 🧪🌎🌐🦑🐟 thetyee.ca/News/2026/04...

i’m doing some data analysis today and laughing at my field notes about the sturgeon clearly this one sturgeon was quite a thiccccck gal, “huge, very fat” was how we decided to convey this in the notes science should also be fun yall!!! take unhinged notes!! make yourself laugh later!! 🧪👩🏻‍🔬🌎🌐

Roughly half of STEM PhD students in the U.S. are international students. 75% of them stay in the U.S. long term after graduating to contribute their skills to U.S. scientific research and development. Cutting international student visas hurts U.S. science now and long into the future.

Sunday

Big Bear Bald Eagles. The rain lightened up a bit and Jackie gave the eaglets a snack while they shook off the rain drops. The eaglets didn't get too wet, and Jackie quickly tucked them back under her, over their objections. #birds

Yesterday morning was peak Saguaro! 🌵 🌼 (13 blossoms?!)

Cope’s Gray Tree Frog is confident this trellis was placed here specifically for her and would like to request more garden accessories that blend with her skin tone😄

Ontario’s Endangered Species Act is officially dead. The new Species Conservation Act is replacing it, but leaves many plants and animals — and their habitats — without protection. via @leahbortskuperman.bsky.social thenarwhal.ca/ontario-spec...

Our mural on native plants and pollinators at H. A. brown elementary school in Kensington starts today! We’re still shy of our fundraising goal, so if anyone would be down to support educational art in an underserved area of Philly, I would really appreciate it! givebutter.com/KenzoMural

Less dams, more fish! 🐟🏞️ Restoring rivers and habitats cannot wait.

"One of the most important things food businesses can do to tackle food waste is to measure and publicly report food waste data” This should be nade mandatory!🍉🍏🍓🍞

happy #sturgeonsaturday (on sunday)! 🧪👩🏻‍🔬🌐🦑🌎 did you know that sturgeon rely heavily on scent & feel to find food rather than eyesight? in the photo you can see the barbels (like whiskers) & the 2 nostrils - which are basically the same size as the eye! these strong sniffers are quite impressive 👃

i mixed my two most frequent pastimes: worrying & pottery, with my love for the sea 🫶🏼 i always need to fidget with things, these are a sensory dream with a smooth & rougher side and i love them sm :) if this resonates with you the link is below💫🌞🌀 www.madisonearhart.com/pottery-coll...

Once upon a time I just admired nudis and sea slugs. But it was not enough. Now apparently I'm creating an R package to celebrate their colour palettes? 😅 First up, my Sydney fave, Hypselodoris bennetti. #rstats #nudibranch #dataviz 🦑🐙🧪 #marinelife #invertebrates

It’s the time of year when fishers start moving around a lot, leaving all sorts of beautiful snow tracks. Bonus points for wolf tracks in a spot that wolves don’t usually occur!

We have 2 cool shirts! I have to sell them out by early April for 2 reasons: 1) 5 of my family members are staying in the Skype a Scientist stockroom in mid-April 😅 2) I need to fund our mural project which starts the first week of April! They're soft! They're cute! Get a shirt! SquidFacts.net

In our new piece @theconversation.com, we break down pressures facing Canada's migratory caribou — and some solutions identified by Indigenous communities and science.

happy #sturgeonsaturday ! this is the time of year that sturgeon wake up from their overwintering cuddling and move around in search of food! in the Fraser River, BC this usually aligns with the eulachon spawning run, a crucial sturgeon food source, full of fat after a long winter 🍽️ 🧪👩🏻‍🔬🌎🌐🦑🐟

wanna follow a suuuper cool group of people leading a variety of conservation efforts??? look no further!!! @libererofellows.bsky.social starter pack is here 🤩 🧪👩🏻‍🔬🦑🐟🌐🌎

hiiiiiiiiii it’s me!!! i am so thrilled to announce i’m now a liber ero fellow!!! 🫶🏼💫🥰 so excited to start this journey and continue working in white sturgeon conservation i’ll be identifying population stressors that could be leading to mortalities and declines across british columbia 👩🏻‍🔬🧪🌐🌎🦑🐟

The Voyageurs Wolf Project of Northern Minnesota tags & documents grey wolf ecology & behavior: www.voyageurswolfproject.org The video you see here is confirmatory proof: Wolves. Love. Blueberries. As much as 83% of a wolf's calories in summer months comes from eating berries.

new paper and illustrations 🧪👩🏻‍🔬🌎🌐 We asked are embryos understudied in conservation physiology? Turns out, despite the increasing recognition of the ecological importance & sensitivity of embryos, we found no evidence that embryo research has gained traction over the past 10yrs paper link below👇🏼
