Did we just come up with a great idea for a nature paper that gets us kicked out of JVP?

Excited to talk about zoology with prospective students for natural sciences day at Bowie State! Had to get out the T-Rex of course.

I should clarify, a student asked me if a lamprey was a type of leech and I knew the answer was no, but I had literally no idea what type of animal a leech is.

Artomyces pyxidatus, the Crown-tipped Coral or Candelabra Coral fungus, was not seen in the UK over the entire 20th century, its last record in 1886 until a spate of recent findings around 2022, which is when I found this specimen (in East Kent). Where did it disappear all this time?

A new spider genus named after Shuqiang Li | Blog โ€œI am delighted that the authors have named a spider genus after me," the ZooKeys subject editor commented.

In a new ZooKeys paper, authors named a new spider genus after our subject editor and prolific author Shuqiang Li!

We congratulate Shuqiang on this distinction.

One of the best parts of teaching is getting to answer questions about paleontology. So far today have gotten to talk about Megalodon, wooly mammoths, cloning, and dinosaurs. What other job would you get that?

There is a placoderm named Bothriolepis rex, maybe there needs to be a Nanobothriolepis?

Mandeville Lab Fish are so delightfully weird. We study the evolutionary genetics and ecology of freshwater fishes, plus a few more things, at Northern Michigan University

I'm recruiting a new master's student for fall 2026 in my lab at Northern Michigan University @bionmu.bsky.social ! Students with interests in evolution of freshwater fish are encouraged to apply. Please see our lab website lizmandeville.github.io and the attached advertisement for more information.
