SSB is launching a new mentorship program to cultivate relationships among members of the systematics and phylogenetics community.

We're now recruiting a pool of mentees and mentors for our first group of participants!

So! Evolutionary biologists: be careful using hybridization summary statistics if you have substitution rate variation, and consider using methods that do not assume constant substitution rates. (4/4)

We also found the power to detect hybridization events decreased when there were more hybridizations, for all three tests. So it seems that hybridization events can "hide" each another if they occur within a small subset of taxa. (3/4)

Variation of rates between lineages had the largest impact on false discovery of reticulation (type-1 error) across all three methods. D3 was the most sensitive with ~80% type-1 error.

My first paper from my PhD w/ @cecileane is available on bioRxiv! We found that variation in substitution rates impacts the power and false discovery rate of the D-statistic, D3, and HyDe. 🧵 1/4

howdy, folks! 👋 here goes an #introduction of sorts:

I'm a PhD student at UW-Madison, studying phylogenetic network methods, with a background in plant systematics. I write code in #julialang, with some Python and R for good measure.

outside of PhDing, you can find me running (like, a lot) and reading (also quite a lot)!
