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!

That's Not a Hybrid: How to Distinguish Patterns of Admixture and Isolation By Distance | Molecular Ecology Resources onlinelibrary.wiley.com/doi/… 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: academic.oup.com/jeb/advance…

The paradox of predictability provides a bridge between micro- and macroevolution

Abstract. The relationship between the evolutionary dynamics observed in contemporary populations (microevolution) and evolution on timescales of millions

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.
