How do baleen whales get so big? Their fetal growth rate is off the charts compared to all other mammals. For all others, large offspring come from increasing the length of pregnancies. For baleen whales it's from insanely fast growth

Pinnipeds (#seals and #sealions) put their hearts in to 'taking a nosedive'. oceans.ubc.ca/ocean-idioms/

When we say "nosedive," we usually mean disaster—but not for pinnipeds. 🦭 Find out ⬇ how seals and sea lions are uniquely adapted to dive deep🫀

Meanwhile, politics in Canada.

Similar plan was hatched in Canada - I think in the 60s?- designed I believe to preserve hake. This one entailed using 50 cal machine guns but was foiled due to an ammunition mixup.

Fortunately, the next Comparative Nutrition Society meeting will be held in Victoria, Canada in August 2026. Check it out at cnsweb.org

Folks, exactly 5 years ago today I made this offer, & I'll do it again.

Many graduate students are in danger of losing their one field season for collecting data- in March 2020 because of the pandemic, now because of Musk-Trump BS. This means that many won't be able to finish graduate school. 🧪🧵

It’s difficult if co-authors “own” part of the study and can raise a fuss if excluded. But if it is a matter of different visions, perfectly legit to give them opportunity to bow out of YOUR paper. But get it in writing so there are minimal hijinks after publication.

As President of the Canadian Society for Ecology and Evolution @csee-scee.bsky.social I wish to convey our strong support for this letter (which we have signed on to) and our colleagues and allies in the U.S. We stand with you and are here for you. Science is not a partisan issue. It benefits all.

Canadians in Solidarity with Stand Up for Science By adding your name below, you are joining a growing movement of Canadians who believe in the power of science to inform policy and serve the public good. Your name will automatically be added to our ...

Canadians in solidarity with Stand Up for Science.
I signed. The assault on science in Canada under the conservative Harper regime was not as extreme as the MAGA one, but came from the same desire to prevent scientists from speaking truth to power.

“I wish it need not have happened in my time,” said Frodo.
“So do I,” said Gandalf, “and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us.”

I feel like I can’t even email my colleagues without fear of getting them in trouble for interacting with this dangerous foreign national. What a state of affairs for the science community. The ramifications will be global.

Great, intriguing paper. Will be sharing with my lab. Despite the fact that the first rule of Fight Club is ….

Oh, the irony of today’s competing newspaper headlines: “US stocks tumble on fears of Chinese advances in AI” and “possible funding freeze for US scientists”.

As a grumpy old man who studies marine mammals I am bemused/confused by the sudden influx of followers on this platform who only have glamour shots on their profiles. I hope they are not mistakenly after my fortune!

“et al.” should always have a period as it is an abbreviation for “et alia”. Yes, I was cruelly forced to take Latin as a child.

I am recruiting two funded graduate students (1 MS, 1 PhD) to join the lab and the Fisheries, Wildlife, and Conservation Sciences program at Oregon State University!

‘Like a giant bird box’: the volunteers building huge snowdrifts for Finland’s pregnant seals As warmer winters melt the snow drifts that endangered Saimaa ringed seals raise their young in, humans are giving them a helping hand

Great to see coverage of the important work by Finnish colleagues on Saimaa seal conservation. Direct hands on effort by small dedicated teams can have real conservation impact. 🧪🌍🦭🦑
