Check out our two last papers on epigenetic clocks for age estimation in fish. One, the first review on the subject, tells you everything you wanted to know about these clocks frontiersin.org/articles/10.… ...
... and the other shows how to build them for applications in fisheries management and conservation biology frontiersin.org/articles/10.…

What a wonderful week! living the 30th CECE & ISFE joint congress in Portugal to the most with great scientists and friends :D couldn't ask for more.. and then I even won the 1st prize for the oral talk! Thanks! What an honour!! @GroupBiolRepro @ICMCSIC @J_Exp_Biol @ceceisfe2022 – at Lisbon, Portugal
Unexpected results! We report that, in a global warming scenario, fish with chromosomal sex determination (SD) may not necessarily be better protected against the masculinizing effect of high temperature than fish with polygenic SD. doi.org/10.1016/j.envres.202…
ALT Zebrafish natural strains Ekkwill (EKW) and Nadia (NA), both with chromosomal sex determination (SD) and theoretically resilient to environmental perturbations, are readily masculinized by elevated temperature as the domesticated AB strain, which has polygenic sex determination and is easily influenced by environmental temperature.
Published! The evolutionary history of sexual systems in fish, with >4600 sp. analyzed. Separate sexes is the ancestral system, and sequential hermaphroditism is an intermediate step in the evolution of simultaneous hermaphroditism.

In a study carried out at Dr. Gen Hua's lab, we uncover transposon-induced epigenetic silencing in the X chromosome. This represents a previously undescribed
solution in animals relying on dmrt1 function for sex determination. Check the study at: doi.org/10.1186/s12915-021-0…

What exactly is a hermaphrodite fish and how many are there in the world's oceans? How many undergo the process of sex change? Why are there so few freshwater hermaphrodite fishes? Find answers to these and other questions in our latest paper: rdcu.be/cyYtE

Pre-print alert! I am so excited. This has been a long and fun journey! The evolutionary history of sexual systems in fish (well, 4740 spp) from a phylogenetic point of view but also considering life history traits and a new theoretical framework #TeamFish biorxiv.org/content/10.1101/…
