I'm excited to release the newest version of my free applied biostats textbook. It's tidyverse style, clarkia inspired and loads of fun Im putting this down until the end of the semester, when I'll add and polish additional chapters, but the 1st 21 are pretty solid yanivjb.github.io/biostats-book

1/11 🐟 2nd new preprint today from @chasedbrownstein.bsky.social We investigated how losing the swim bladder, the organ that most fishes use to control their buoyancy, has shaped the diversity of ray-finned fishes over 90 million years of Earth history. The results surprised us. 🧵

For folks interested I just posted my keynote on ARGs from #PEQG26 on youtube (with permission). Thanks again to @genetics-gsa.bsky.social and organizers for what was a wonderful conference (except for the 24hrs prior to my talk when I was too nervous to sleep or think straight) youtu.be/ntJOdZd0mwc

New preprint led by amazing undergrad @ogolwala.bsky.social! Within ~10,000 years, sperm traits have diverged between trophic specialists in this young radiation of pupfish. Hybrids are fertile, but show transgressive sperm kinematics and reorganized integration. With @fishspeciation.bsky.social.

Excited to share new work on two sex-linked pigment traits in Xiphophorus! This project was led by undergrad @lagiven.bsky.social, who’s worked with me for the last 3(!) years. www.biorxiv.org/content/10.6...

Two melanic pigment patterns are associated with a sex chromosome-linked oncogene in the mountain swordtail Xiphophorus nezahualcoyotl

Sex-linked traits are widespread, but their genetic architecture has been challenging to characterize, due in part to the repetitive and structurally complex nature of sex chromosomes. In swordtails a...

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

Our new paper is online! We found that 1) today's shark & ray diversity was already reached ~100Ma; 2) that the K/Pg extinction was not catastrophic; 3) that the max diversity was reached ~50Ma; and 4) that today's diversity is depleted compared to the past. www.cell.com/current-biol...
