This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

We just published a review 🗞️😁:

‘The ecology of adaptive radiation’ revisited: A 25-year reflection

Dolph Schluter’s book inspired the interest in adaptive radiation, and we wanted to revisit it.

For Day 9 of #25DaysOfFishmas, we're heading back to Australia to meet perhaps the most evolutionarily isolated species on our list. This is Lepidogalaxias salamandroides, the salamanderfish, which is not only the only member of its family, nor order, but is the only member of its *superorder*!

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!

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)...

La Niña Years—Our “Cool” Years—Are Now Warmer Than El Niño Years Every year, Earth’s temperature changes a little. Sometimes it gets hotter, and sometimes cooler. Scientists track this closely to understand how our climate is changing. But it’s not just about clima...

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.

A scientist presents her take-away slide on a large dark stage. It reads: Take-away • Zebrafish can evolve improved growth at warmer temperatures • Thermal performance curves can undergo a left or right shift • Ectothermic vertebrates may adapt to global warming by enhancing performance • Role of selection in shaping thermal resilence

A scientist presents her title slide on a large stage, it features a beautiful picture of a brook trout.

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!

Second paper this week from #NearLab!

We're not attending ICFT. Bigger issues at hand. We've put a lot of effort over the years in fine-scale positioning arrays, so we were looking forward to attending.
Oh well....

Later in the 1930s, Elton visited the station on Lk Opeongo.
It likely reflected correspondence over the years between him and Dymond.

Later in the 1930s, Charles Elton visited the park & Harkness... greeted by folks from Harkness at the train station in Pembroke, Ontario.
Elton & Harkness Lab...now that's something.
7/7

Elton's book, Dymond & MacDougall were pivotal in bringing a modern ecosystem view to Algonquin Park.
X/4

Frank MacDougall, superintendent of Algonquin Park at the time, worked closely with Dymond to bring a science element to new park directions. Elton's concepts of food chains, pyramids, and productivity were promoted by Dymond.
