Come see my talk on guppy sex chromosome evolution at the Fish 3 session on Tuesday at #CSEE2026! Back-to-back with @joellelafond.bsky.social !
📢 NEW GENOME ALERT
In #G3journal, @squarehare.bsky.social, @judithmank.bsky.social, and team generated a genome assembly of the Amazon guppy, Poecilia bifurca and showed how this species shares sex chromosomes with related species, albeit with substantial Y chromosome degeneration. buff.ly/lM7etkw
We're recruiting!
We're looking for two graduate students to join us at UBC in Vancouver.
Fully funded and open to global applicants, with flexible start-date. Topics include theory, bioinformatics, and microbiology.

Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

Also, a big shoutout to my coauthors who supported me through this project: Yuying Lin, @squarehare.bsky.social and @judithmank.bsky.social!
I am also grateful to @fondsrechercheqc.bsky.social for supporting my research.

Very pleased to see this out. Our new Poecilia picta genome shows rapid Y degeneration in a young XY system — rapid gene loss and Helitron accumulation, plus compensatory gene traffic to autosomes. Led by @joellelafond.bsky.social with Yuying Lin & @squarehare.bsky.social doi.org/10.1111/mec....
I’m excited to share my new paper! 🤩 We showed that maternal sucrose intake during pregnancy alone disrupts testosterone and allopregnanolone levels in critical regions of the fetal brain 🧠

Sex chromosome evolution has traditionally been viewed as a linear, time-dependent process. However, numerous comparative studies across diverse taxa have revealed that homomorphy can persist over lo...
Intake of added sugars, such as sucrose, is high globally. In rats, a maternal high-sucrose diet (HSD) from 10 wk before pregnancy to embryonic day (E…
Just in time for her #eseb2025 poster on Thursday, @squarehare.bsky.social 's paper on the Poecilia bifurca sex chromosomes was published today academic.oup.com/g3journal/ad...
Mankees are headed to #CSEE2026! Check out
@squarehare.bsky.social's and @joellelafond.bsky.social's talks about Poecilia sex chromosomes, and
@vdbijl.bsky.social's talk about evolutionary repeatability of male colour.
Congratulations Dr. Fong! First PhD from the UBC Mank Lab! @squarehare.bsky.social

Now out! How important is social experience in male mating behavior? @corrallopeza.bsky.social found that experienced males were more likely to coerce non-receptive females, but did not change overall preference onlinelibrary.wiley.com/doi/10.1002/... w/ @vdbijl.bsky.social @idarolti.bsky.social

Lydia Fong’s poster is on Thursday, P03.077. Genome of the Amazon Guppy (Poecilia bifurca) reveals conservation of sex chromosomes and dosage compensation. The preprint for this is at www.biorxiv.org/content/10.1... @squarehare.bsky.social #eseb2025 5/n
