Four years ago, Jesse Bloom announced the recovery of SARS-CoV-2 sequences and suggested they could come from very early COVID-19 patients.
Zach Hensel and I found out that Bloom's claim relied on the deliberate omission of a January 30, 2020 collection date contradicting his narrative. 🧪 #PopGen

100 downloads of my 'Genetic structure and relatedness of brown trout (Salmo trutta) populations in the drainage basin of the Ölfusá river, South-Western Iceland' article published in #OpenAccess journal @PeerJLife
Huh, folks. It seems that I don't get something about #Dryad
I'm looking for a code example for a bit exotic #popgen tool and 3 papers in a row (from 2021 - 2024) have "data and code available on Dryad", but doi gives an error and direct search on Dryad "dataset not available".
Is it just a sneaky way of authors to flip a bird to the #openScience practices required by the journal?
Does it make sense to poke @datadryad or it's journal's team who should sort this out with the authors?
Good reviews on "Gene flow and habitat heterogeneity shape coexistence dynamics of Arctic charr morphs in connected lakes" at Molecular Ecology
Rejected but encouraged resubmission (which I hate, its plain metric-playing)
The main result being #GeneticStructure of four sympatric morphs in #thingvallavatn #Iceland

Leirvogsá river runs from Leirvogur up to Lake Leirvogsvatn
Leir-vogur translates to clay-cove
Above the waterfall is the lake, and in it the brown trout with lowest level of genetic variation

Harpy v2.0 is almost across the finish line, and I wrote a lil' post about what linked-read sequencing actually is and how we evaluate the data differently than standard short-read data. It's a quick and easy read (with pictures!), highly recommend 🤓

In a paper led by J. Pekar now available online, we revisit claims made last year by Lv et al. about early SARS-CoV-2 sequences.
We find that their two T/T genomes were sampled too late to be likely evolutionary intermediates between A and B lineages, and are instead likely derived. ▫️1/ #PopGen

Last week, I updated #adegenet on #CRAN. This is an important update as it fixes a memory overflow problem for SNP data that has existed since 2016.
If you use #PopGen packages that import adegenet (e.g. #poppr, #vcfR, or #dartR), then you should update.

That time of year again: postdoc fellowships available at the Unviersity of Toronto. Get in touch if you want to apply to work with me on some evolutionary theory.
3 years (and 2 kids) later, I finally revised the manuscript:

we develop a #popgen method to locate genetic ancestors from tree sequences and apply it to arabidopsis thaliana.
software is ready to be applied to any dataset with Relate trees:

Hi everybody,
I am pleased to share with you my latest work in collaboration with Augustin Cléssin and Nicolas Lartillot:

GC-biased gene conversion (gBGC) is a process that distorts the segregation of heterozygous AT:GC polymorphisms during meiotic #recombination. This genome-wide non-Mendelian segregation has been shown to be a major source of #genetic load, earning the nickname of “Achille’s heel” of #genomes. (1/2)
