My research addresses the interactions between micro- and macroevolution In fishes. I am particularly interested in the impact of variation in life history traits (e.g. diadromy, amphibious behavior-mudskippers, & breeding behavior) on population/speciation patterns

Help us share the diversity of people working with fishes! Quote tweet this (or each other) with a pic/what you do!

I study the ecology and conservation of gars and other “ancient” fishes!

[Joel Corush @JCorush]

I'm looking for a Ph.D. student for Fall 2026!

Interested in comparative studies and trait evolution in fishes?

I'm pleased to see this publication out led by @JCorush that I helped with on the role of geological and anthropogenic factors driving genetic structure of mottled sculpin in Illinois, where it is a state-threatened fish species. https://t.co/8yvpJOcVrJ

Very important paper! Indeed, I have also noticed that Structure/Admixture plots are often overinterpreted as introgression.

Thankyou @MasahitoTsuboi for leading this author team behind this paper in @JEvBio!

I am very excited about this and a proud member of the team. We now hope that we have made colleagues aware of an important bridge between micro- and macroevolution:

@drelopara Thanks! I have not look into that book yet, I'll check it out.

[Joel Corush @JCorush]

Eco/Evo friends:
I will be teaching 2 upper-level undergrad/grad classes in 1) Evolution & 2) Vert-Zoology for the first time! If anyone has a syllabus, course outline, notes, book suggestions, or anything else you would be willing to share, I would greatly appreciate it.

Famed lions’ full diet revealed by DNA — and humans were among their prey https://t.co/9rcteIa1wj (a round-about way to get into Nature 😍 it was nice chatting to Emma Marris about these lions!)

🚨Our paper testing the impacts of salinity on phenotypic rates in nearly all ray-finned fishes recently arrived!🚨

Salinity is generally a weak predictor, but predictive potential for freshwater-brackish, lake living, and larger species.

Pleased to share a new study led by my student @CucalonV on resolving the distributions of Forbesichthys cavefishes using genomics. Many collaborators to thank including @JCorush @cavemander17 @ihartcaves @Mark_A_Davis79 and others not on X. https://t.co/Nqnd94Z5BQ

[Jeremy Beaulieu @phylieu]

I'm hiring a post-doc to work on a new NSF-funded project. This is funded up to two-years and is in collaboration with Andrew Dickerson at UTK. Start date is very negotiable.

Job description here: https://t.co/GriuCY0ufI.

Contact me if you're interested. Please RT!!!

[Milton Tan @mtanichthys]

As a reminder I'm searching for a PhD student interesting in working on our NSF-funded project on minnow evolution and diversification. I made a post to EvolDir:

[Milton Tan @mtanichthys]

I am excited to announce our @NSF grant has been funded to study the evolution and diversification of N American minnows, including genomics/phylogenomics and comparative phylogenetic methods.

This includes funds for a postdoc and PhD student! If interested, please reach out!

[Joel Corush @JCorush]

Collecting minnows with @mtanichthys and @CucalonV on our way home from #JMHI24 and caught my first Juvenile Gar from the Allegheny River.

[Joel Corush @JCorush]

Great talk by @CucalonV on minnow distribution and hybridization @IchsAndHerps #JMIH24

[Milton Tan @mtanichthys]

If you're looking for a PhD lab to study fish evolution and are going to be at #JMIH24, let's talk.
