Finally, this is the first published paper by undergrads Tate Linden, @AbbyEBurtner, @JohannahRickman, & @annikam321; @SESantanaM's first squirrel paper; and my first "senior author" paper! Stay tune for more #TeamSquirrel content 9/fin

Overall, our work contributes to the growing understanding of mammalian body shape evolution and how it is influenced by body size and locomotor ecology, in this case from robust subterranean to gracile gliding squirrels. 6/x

[Chris Law @Chris_J_Law]

Lastly, we found that the relative length of the ribs and elongation or shortening of the thoracic region contributes the most to body shape evolution across squirrels. 5/x

[Chris Law @Chris_J_Law]

Next, we found that only ground squirrels exhibit a relationship between forelimb length and body shape, where more elongate species exhibit relatively shorter forelimbs. In contrast, there was no relationship between relative hindlimb length and body shape. 4/x

[Chris Law @Chris_J_Law]

The scaling patterns of the morphological components underlying body shape also differed among ecotypes. 3/x

[Chris Law @Chris_J_Law]

We found that body shape scale with body size, but these allometric patterns differ among squirrel ecotypes: chipmunks & gliding squirrels exhibited more elongate bodies with increasing body sizes whereas ground squirrels exhibited more robust bodies with increasing body size 2/x

[Chris Law @Chris_J_Law]

The first #TeamSquirrel paper is published! Led by Tate Linden, we tested scaling patterns of body shape, body size, & limb lengths among squirrel ecotypes and described the underlying morphological components that contribute to body shape evolution 🧵1/x https://t.co/0gDl8gZNex

Excited we got to bring a 9 undergrads to #SICB2023 this year! Thanks to everyone for giving them a great conference!

[Chris Law @Chris_J_Law]

All undergrads are accounted for! Be sure to stop by the poster session later today to learn about squirrel limbs and carnivoran sexual dimorphism! #SICB2023 @SICB_DCB_DVM

[Chris Law @Chris_J_Law]

And that wraps up two years of #TeamSquirrel at the @burkemuseum! Will miss my undergrads 😭 But now time for them to start the fun writing part 🤓

@AbbyEBurtner @JohannahRickman @annikam321

[Chris Law @Chris_J_Law]

And everyone did an awesome job on their presentations! 🦇🐿️🐺

@AbbyEBurtner @annikam321 @JohannahRickman

[Chris Law @Chris_J_Law]

My 7 undergrads are presenting at the @UW Research Symposium tmrw!

-2:30-4pm (Poster Session 3) in MGH 241: poster by Alise, Anna, & Rada
-3:45pm (Session O-2D) in MGH 251: talks by @AbbyEBurtner, @annikam321, Tate, & @JohannahRickman

[Chris Law @Chris_J_Law]

I definitely recommend checking SegmentGeometry out! #TeamSquirrel members @JohannahRickman and @AbbyEBurtner have been getting great data from it!

[Chris Law @Chris_J_Law]

My 7 mentees just submitted 4 project abstracts to the UW Undergraduate Research Symposium! 🦇🐿️🐈 Happy #WomenInScience Day!

@AbbyEBurtner @JohannahRickman @annikam321 @SESantanaM

[Chris Law @Chris_J_Law]

First time taking students to a conference was a success! Thanks to all who made their first poster presentations a great experience!! #SICB2022

[Sharlene Santana @SESantanaM]

Well done @UWBiology students @AbbyEBurtner and @JohannahRickman, and @Chris_J_Law as their mentor!! I hope you got lots of useful feedback on your projects and are having a great conference. Go #TeamSquirrel and #TeamBatLimbs! 🦇🐿️

[Chris Law @Chris_J_Law]

And please reach out them if you have any questions about their posters: @JohannahRickman representing #TeamSquirrel and @AbbyEBurtner with bat limb evolution!
