Wishing you calm seas @alltooclearfilm.bsky.social! In partnership with @harknesslab.bsky.social and @lakeheaduniversity.bsky.social, we will be sinking an autonomous up-looking echosounder that will ping 24/7 to help understand the diel behaviour of fish and zoop at Sup Shoal. Be sure to tune in!

Aren't they lovely? Congratulations to my great colleague Bud Freeman, this is the culmination of over a decade of work! www.mapress.com/zt/article/v...

1/ Who published the first freshwater food web? American ecologist Victor Shelford may have done so (see below) in his classic 1913 monograph "Animal communities in temperate America as illustrated in the Chicago region", a book that inspired Charles Elton (who cited it in Animal Ecology)...

Some great talks on fish metabolism, thermal tolerance, and bioenergetics by folks from @trentuniversity.bsky.social at this year’s #SEBconference in Antwerp, Belgium. @sebiology.bsky.social @erinmcstewart.bsky.social @jaydebon.bsky.social @chris-on-fish.bsky.social

Think La Niña years are “cool”? Not anymore. Even our coolest years today are hotter than the hottest El Niño years of the past. Climate change is flipping the script — fast. A huge thank you to @zacklabe.com for his amazing graphic!

Home is where the heat is (for brook trout that is) Intrigued? Then check out this latest #ConPhys in Action piece, explaining the importance of local conditions to 🐟 temperature tolerance, and therefore for #Conservation planning. Comments on Stewart et al (links in 🧵⬇️ )

A terrific afternoon for fish biology here at #SEBconference ❤️🐟 Great talks by @leeuwisrobin.bsky.social, Moa Metz, and @erinmcstewart.bsky.social about different ways that fish respond to climate warming!

Meta-analysis reveals that density-dependent growth, survival, and their trade-off vary systematically among habitats and taxa buff.ly/DgfgJYQ

Second paper this week from #NearLab!

Elton's day. @ecoinvasions.bsky.social thanks for the reminder Interesting Harkness connection... 1/x

Today at Harkness. Thanks Lucas....

Thanks, Louise, for highlighting this. Agree. Fieldwork brings authenticity - for the public, for ourselves, and for applications. Undergrads & grads from our field station are always in demand.

Shout out to @ucsandiego.bsky.social and @scrippsocean.bsky.social for keeping this going right now! keelingcurve.ucsd.edu

🙁 Removal of more than 250 endangered southern steelhead trout took place last Thursday at Topanga Creek in a rescue operation led by the California Department of Fish and Wildlife.

There are as many as 7 species of redeye bass swimming southeast US streams. Redeye fly fishing is similar to small-stream trout: beautiful streams, surface action, small but striking fish. I've caught 5 redeye bass species & hope to return for Warrior & Cahaba bass this year. #flyfishing

Never forget that Exxon built their own climate model in the 1970s that correctly predicted climate change from the burning of fossil fuels

The future is #catostomidae... firmly believe that if there's a sentinel species that can tell us about enironmental changes, this group of fishes is it. Widely distributed, rarely targeted by anglers (and therefore don't need to worry about fishing mortality), and, I mean, just look at that face

Yes. Agree. Catostomids are important in many aquatic ecosystems. Abundant and functionally unique.

We're back in February for more conservation science! Join Dr. Mark Ridgway for the scoop on Algonquin Park lake fish. There's more going on beneath the waters than we thought!

📣 Just published in @conphysjournal.bsky.social with @jacobbowman.bsky.social, Chris Wilson, and Graham Raby How much does upper thermal tolerance vary among wild populations of brook trout? What drives this variation? 🌡️ 🧵1/5 doi.org/10.1093/conp...

A friendly reminder that abstracts for ICFT 2025 are due at the end of the month! See the conference website for details. We want to be able to provide a quick turn around of abstract acceptance before registration begins!

OTD in 1912, Alfred Wegener delivered a lecture propounding the theory that our modern continents were formed by the splitting and drifting apart of an ancient supercontinent, which he named Pangea. Due to his failure to offer a plausible mechanism, he was widely ridiculed. 🧠🗃️⚒️ 🧪 #HistSTM #PhilSci

After 24 years of work, I’m thrilled to announce the TYMEFLIES dataset, which comprises metagenomes from Lake Mendota (Madison, WI), collected roughly every 10 days (471 samples) for 20 years! @quendi.bsky.social @robinrohwer.bsky.social rdcu.be/d5put A thread…

There is a lot to look forward to in 2025 and one of the big things is the Black Bass Symposium - To be held at the @amfisheriessoc.bsky.social annual meeting. August 10-14, 2025 in San Antonio, Texas. Learn more at: storymaps.com/stories/baf0...

One of the world's great long-term studies of marine and aquatic ecology. Happy birthday CalCOFI from an 88 yr old aquatic field station.

Yesterday was our final day of tagging spawning lake whitefish on Lake Simcoe. We will be tracking the movements of these fish around the lake.

Well done, Wisconsin DNR. Brook trout conservation is important.

Wanna learn more about what we do? Have a look at some of the #hydroacoustic services we provide. Our promo doc includes clickable links to videos, echograms, case studies and examples. Thx for check'n it out! 📌 www.milnetechnologies.ca/MilneTech_Do...

Today. View from the boat ramp. Tomorrow is our last day on Lake Opeongo for 2024. Downloads and gear removal for winter before ice... Should be a brisk run around the far point & up the lake.

Exactly. Leave the garbage site. This process has been too drawn out for science folk. Thank you bsky

This was a cool study and fun paper to write. We followed acoustically tagged lake around with a multibeam sonar to study their behaviour. Observed attacks on prey fish schools and interactions with other lake trout.

Hey everyone - thanks for joining me here. I'd love to take the opportunity to share my most recent publication. Check out the power of volunteers to collect critical information on our most abundant group of migratory fishes in the Great Lakes! link.springer.com/article/10.1...

Just for fun, here is the echogram video for Lake Trout Tag ID 4 from Fig 6 panel b. Note the Cisco school displaying "Fountain Effect" upon Lake Trout attack from below. Super windy day so hope video doesn't make you feel too sea-sick!

Time for the @bsky.app community to see one of my favorite visualizations of climate change... "Shifting Distribution of Land Temperature Anomalies" by svs.gsfc.nasa.gov/5211/ ⚒️🧪
