We are meeting this semester (Fall 2024) on Fridays from 1:20 to 2:20 in PBB 303 (i.e. BioPharm 3rd. floor fishbowl). Subscribe to systematics listserv to receive emails containing connection information (or write to someone listed in Contact Info).

This first meeting, those who are registered will sign up for a date to lead, and we’ll have an informal discussion of what everyone’s working on and what kind of seminar they want this to be this semester.

September 6, 2024

This week we will start working on our minitheme of species delimitation by reading this chapter from a recently published book:

ML Smith and BC Carstens. 2022. Species delimitation using molecular data. Chapter 7 in: JS Wilkins, FE Zachos, and IY Pavlinov (eds.), Species problems and beyond: contemporary issues in philosophy and practice, 1st ed. CRC Press ISBN 9780367855604.

September 13, 2024

We will discuss this paper, which is one of the few methods that does not require many loci.

N Puillandre, A Lambert, S Brouillet, and G Achaz. 2012. ABGD, automatic barcode gap discovery for primary species delimitation. Molecular Ecology 21:1864–1877. DOI:10.1111/j.1365-294X.2011.05239.x

Nick chose the paper below to discuss this week. He says “This paper will examine the difference in results between 5 different delimitation methods, including ABGD. It also is on the more digestible side as it only involves one mitochondrial locus, which should offer us more chances for discussion about barcoding.”

C Blair and RW Bryson Jr. 2017. Cryptic diversity and discordance in single-locus species delimitation methods within horned lizards (Phrynosomatidae: Phrynosoma). Molecular Ecology Resources 17:1168–1182. DOI:10.1111/1755-0998.12658

Discussion of this paper was postponed until October 4 because we did not have a quorum.

September 27, 2024

Mark Stukel selected this paper introducing SPEEDEMON:

J Douglas and R Bouckaert. 2022. Quantitatively defining species boundaries with more efficiency and more biological realism. Communications Biology 5:755. DOI:10.1038/s42003-022-03723-z

October 4, 2024

This week we are going to discuss the paper (Blair and Bryson 2017) that Nick chose for Sep. 20.

October 11, 2024

Zach suggests the following two papers related to GDI (Genealogical Divergence Index).

AD Leaché, T Zhu, B Rannala, Z Yang. 2019. The spectre of too many species. Systematic Biology 68(1):168-181. DOI:10.1093/sysbio/syy051

ND Jackson, BC Carstens, AE Morales, BC O’Meara. 2017. Species delimitation with gene flow. Systematic Biology 66(5):799-812. DOI:10.1093/sysbio/syw117

Zach suggests we read the Jackson et al. paper first and save Leaché et al. for later.
