Evolutionary rate incongruences in squamates reveal contrasting patterns of evolutionary novelties and innovation

Abstract. Understanding the rate of phenotypic evolution can reveal fundamental aspects of organismal evolutionary trajectories. Hence, several studies hav

I am extremely happy to see that our review on fossil tip-dating is out in early view in Systematic Biology! A huge thanks to all the authors of this massive project (@heckeberg.bsky.social, @basantakhakurel.bsky.social, Gustavo Darlim, and @hoehna.bsky.social)! academic.oup.com/sysbio/advan...

Seeing these after laying down the first volume of Fabre’s Souvenirs entomologiques, devoted to the rearing behavior of predatory wasps, was a treat. Thanks for sharing Marshall!

Today I learned the (very) hard way that R will tell you a file does not exist even when it totally does if the path to it exceeds 260 characters

(in Windows)

(and you can enable long paths, but it is not the default)

I will forever despise whoever named some closely related echinoid genera with a name starting with “Paleo” and others with a name starting with “Palaeo”

A Sunday reading Fabre’s “Souvenirs entomologiques” by the fireplace is a Sunday well spent

Nico Mongiardino Koch @nmkphylo.bsky.social · Jun 26

Actually, I got it wrong, it is -3. I was going with alternating between subtracting -2 - (i - 1)/2 and adding 1, where i is the iteration

A student once asked me why wasn’t I using which.min(x) instead of which(x == min(x)) and I pretended it was for pedagogical purposes

Yeah, it is true that the result deviates from the expectations of ordering variables/observations. If the matrix format that sapply outputs isn’t convenient you can use lapply instead, or you can just transpose it

Nico Mongiardino Koch @nmkphylo.bsky.social · May 21

I think this is because you are not supposed to use sapply on matrices. If you do it probably gets coerced into a data.frame, whose elements are the columns.

Anyways, not long ago I discovered asplit() which is pretty handy when needing the flexibility to work across either margin

I'm recruiting a PhD student to join my lab at the University of New Orleans starting in Fall 2025. Research topics will focus on building and using phylogenies to study the diversification of birds, with an emphasis on Neotropical bird radiations. Contact me if interested.
