Apolline Alfsen@aperegrination.bsky.social · 2w agoLast PhD conference: SEB @sebiology.bsky.social in Florence. Had a great time alongside @johnnyakatura.bsky.social's lab! John also presented a great poster on our FEA project with Lisa Kean, in collaboration with Jordi @featunning.bsky.social Bonus: the Pisa natural history museum was incredible 🐳
@johnnyakatura.bsky.social presents how #XROMM scientific rotoscoping allows us to compare kinematics across species and even infer fossils movements @europexn.bsky.social #SEBconference
Finally out! Trabecular structure in tamarins changes depending on their leaping distance! A collaboration with U. Nguyen, @fabioalfieri2.bsky.social, A. Licht and @johnnyakatura.bsky.social, using my #R package "indianabones". (1/2) #primates #BioAnth #bones #science 🧪🐒🦴🏺 doi.org/10.1002/ajpa...
New paper out! 🦴🐒 In the trabecular bone of tamarin limbs, we found that beyond non-locomotor factors, leaping distance leaves a signal! Thanks to @aveneziano.bsky.social, and colleagues from the lab led by @johnnyakatura.bsky.social Open Access on American Journal of Biological Anthropology

Our work on mammalian hallucal grasping, led by Irene Montañez-Rivera during her time in the @johnnyakatura.bsky.social group, is out now in iScience. A true team effort; thanks to the whole crew for inviting me to contribute a small piece! www.cell.com/iscience/ful...
Very proud of the first paper of the PhD project of Adrian Scheidt.
Journal of Anatomy@journalofanatomy.bsky.social · 3mo ago@johnnyakatura.bsky.social et al., investigate the scaling of internal joint distance (IJD), a surrogate measure for cartilage thickness, across small- to medium-sized mammals. Elbow position had no significant effect on IJD and used these data to model the range of motion (ROM) at the elbow joint

I don't think that the reviewers asking me for higher animal numbers really understand how many 40 goats are. Do you know the CHAOS that comes with dealing with 40 GOATS in an experimental setting! Mice people cannot comprehend. 3 goats alone ate a tarp, a clock, and 2 expensive accelerometers!

Comparisons of climbing behaviors in arboreal mammals indicate that adaptations for vertical descent, including upright postures, played a key role in early primate evolution. doi.org/hbppbb
Climbing behaviors of tree-dwelling mammals unlock insights on early primate evolution
Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures seen in primates.

Our paper, based on a uniquely large dataset of vertical descent behaviours in arboreal mammals, is published in @elife.bsky.social. The findings offer fresh perspectives on reconstructing postures in early primates. You can find the accompanying press release here: elifesciences.org/for-the-pres...

After teaching my motor control lecture, I was pleasantly surprised to run into some Muybridge originals at the Birmingham Museum of art (for free)! Before his photos in 1878, we didn't know how horses galloped because it was too fast to capture, which is why they look so odd in old paintings! 🧪
Our latest paper is just out 🤩! If you enjoy functional morphology and comparative biomechanics, Adrian's work on the internal joint spacing and its implications for modelling range of motion in the joints of mammals, will be something for you. Cheers! onlinelibrary.wiley.com/doi/10.1111/...
