1 week till @sebiology.bsky.social in Florence! Join me for my keynote for symposium A12: "Digital Resilience: Immortalising Biodiversity Through 3D Anatomical Models". Take a walk through the long grass of 3D imaging with me & collect all of my critter cards along the way! 4pm Tues in Modulo 2.1 🩻

A black background with green cartoon at the bottom of the image. Above the grass are 7 card backs that are styled purple with the radiation symbol in the middle. A "critter card" for the spiny lumpsucker in the top middle of the image gives access to a 3D model via tiny link and QR code. Surrounding the critter cards are silhouettes of 7 other 3D models that represent other 3D models in the set.

The Pacific spiny lumpsucker, an inefficient swimmer but a highly efficient suction cup. The pelvic fins have evolved into a strong suction disk on the belly, giving it the ability to anchor itself to substrates. Plate-like structures called "tubercles" provide defense against predators.

A 3D model made from a micro-CT scan of a Pacific spiny lumpsucker, with the skeleton rendered in light brown/beige and the tubercles rendered in a gradient of colors, beginning with pink at the head, and changing from purple, to blue, to teal as you move towards the tail. Outline of the body is rendered in white and transparent. Shown in antero-lateral view (top), anterior view (bottom left), and left lateral view of the head (bottom right). Scale bar at the bottom right is 5 mm.A 3D model made from a micro-CT scan of a Pacific spiny lumpsucker, with the skeleton rendered in light brown/beige and the tubercles rendered in a gradient of colors, beginning with pink at the head, and changing from purple, to blue, to teal as you move towards the tail. Outline of the body is rendered in white and transparent. Shown in dorsal view (top), right lateral view (middle), and ventral view (bottom). Scale bar at the bottom left is 10 mm.

This yellow spotted river turtle from the Florida Museum of Natural History was collected in Colombia in 1957. It's likely it was exploited by the pet trade, as it was once common for people to drill holes in the marginal scutes of the shell to tether the turtle & stop it from wandering away (1/2)

3D Renderings of a contrast-enhanced CT scan of a yellow spotted river turtle, colored in brown (least dense tissues), green (medium density tissues), and yellow (high density tissues). A dorsal view is shown at the top of the image, and a ventral view is shown at the bottom of the image.

Just one week to get your abstracts in for A12 - "Digital Resilience: Immortalising biodiversity through 3D anatomical models"! You'll present alongside our keynote speaker @jaimiagray.bsky.social who will talk about how making CT data and derivatives FAIR can level the playing field for biologists.

Excited to be a co-author on this one in @currentbiology.bsky.social! @tillramm.bsky.social did a fantastic job bringing it all together. A mountain dragon was the *very first* CT scan I ever worked on as an undergraduate, so it holds a special place in my ❤️

Out today in @currentbiology.bsky.social and led by @tillramm.bsky.social! We integrated population genomics, fossils, SDMs, and micro-CT scanning to understand how climate change has influenced extinctions and extant genetic diversity in the threatened Australian mountain dragon #ozherps #genomics

I used my 3D printer to create educational anatomical models of the brains of fish, frog, & lizard 🐟🐸🦎 The (color-blind friendly) colors demonstrate anatomical regions, and the 🧠 are many times larger than their real size. They can be removed from their stands for closer examination/comparison 🧪

Glad to see Vera et al. lead the way for 3D data sharing in Aus. I hope that Ozboneviz 🦴 shows great things that can happen when you share 3D data FAIR-ly. After working on oVert & seeing it be an amazing thing for US collections, it's somewhat poetic that this paper comes from my home state of SA 🥰
