Rapid evolution of X chromosome dosage compensation in poeciliids! Complete compensation evolved in <4 million years, on the green branch, after the split with guppies. Led by Dave Metzger (sadly, not on twitter) biorxiv.org/content/10.110… w/ Iulia Darolti Ben Sandkam

UBC biologist Ben Matthews has been recognized as one of North America’s top young scientists with the 2021 Sloan Research Fellowship. bit.ly/3u3UgIF

Today’s the day. Trip to Mars, 99.9% complete. The most dangerous part comes last: the final seven minutes. Watch my landing live starting at 11:15 a.m. PST / 2:15 p.m. EST / 19:15 UTC. #CountdownToMars x.com/i/events/13602…

Still in awe of the ARCHIVED - NASA's Perseverance Mars Rover landing. I was fortunate to have participated in the FIDO mars rover program with Cornell University and NASA JPL as a high school student Lansing Schools. I hope more programs like this will continue in the future! #STEM #Science news.cornell.edu/stories/1999/0…

Meet Trish Schulte (UBC Zoology) - our speaker for the "The physiology behind phenotypic plasticity in rapidly changing environments" session at #SEBconference 2021 Submit your abstract! Deadline 22 March sebiology.org/events/event/s…

This Wednesday, Pavitra Muralidhar (Pavitra Muralidhar) will be talking about sex chromosomes and genetic conflict! Live stream on YouTube: youtu.be/Oaou-DALXLo ‼️This will be 1 hour earlier for some! Check here: timeanddate.com/worldclock/fix… Q&A on Slack: bit.ly/EvoEco2

Ever wondered how a sex chromosome dosage compensation mechanism evolves de novo? Transposon wave remodelled the epigenomic landscape in the rapid evolution of a novel X chromosome dosage compensation mechanism. Absolutely beautiful work by David Metzger biorxiv.org/content/10.110…

New, updated version of David Metzger's amazing preprint -Transposon wave remodelled the epigenomic landscape in the rapid evolution of a novel X chromosome dosage compensation mechanism. Now with karyotypes and beautiful summary figure by jacelyn! biorxiv.org/content/10.110…

This year’s Crafoord Prize is awarded to Dolph Schluter who has demonstrated that Darwin’s theories about natural selection are true in practice.

So pleased to see Lydia JM Fong 's first first-author paper from her PhD out GBE (Genome Biology and Evolution) ! Evolutionary History of the Poecilia picta sex chromosomes. academic.oup.com/gbe/advance-ar… with Iulia Darolti David Metzger Yuying Lin Ben Sandkam

How does variation in Y degeneration affect Fast-X Evolution? Very happy to see the version of record of Iulia Darolti 's awesome paper at Molecular Ecology! With Lydia JM Fong David Metzger and Ben Sandkam onlinelibrary.wiley.com/doi/10.1111/me…

Congratulations to Patricia Schulte SchulteLab for receiving GIRAFF funding - GenomeBC & IAF - to study: "Genomic tools for predicting climate change resilience in chinook salmon" to develop new tools that can help monitoring and recovering BC salmon species! 🐟

Deep learning reveals the role of copy number variation in the genetic architecture of a highly polymorphic sexual trait. Wouter van der Bijl did it all - selection experiment, pedigrees, neural nets, GWAS - for the architecture of color and pattern in guppies biorxiv.org/content/10.110…

So very happy to see this out at Genome Research . Transposon wave remodeled the epigenomic landscape in the rapid evolution of X chromosome dosage compensation. Absolutely beautiful work by David Metzger genome.cshlp.org/content/early/…
