Comment from Iosif Lazaridis:
"""
Consider this surprising fact:
There was a time during the 1st millennium BC that
a. in the West Mediterranean, Greek descendants advanced the Punic cause, and;
b. in the Levant, Phoenician descendants advanced Hellenism.

This newly-recognized butterfly species is endemic to a single alluvial fan in Waterton Lakes National Park, Alberta, Canada. This adds to a significant list of isolated species occurrences in and near this small park, including 7 relict freshwater species in upper Waterton Lake, brachypterous lake-dwelling stoneflies, and if memory serves, several plant species. A Wisconsinan ice-free refugium here or nearby?

🧬 Deep learning meets genetics! Filip & Nettelblad crack the code on population visualization, outperforming classic techniques with a game-changing contrastive learning approach. 🚀 #GenomicInnovation #MachineLearning #PopulationGenetics https://emmecola.github.io/genomics-daily
On Monday I received this email, sad news:

In #PopulationGenetics there’s the idea of minimum viable population. Is there a similar idea/equation in #Linguistics ? As in the minimum number of speakers of a language before the language disappears? @linguistics
Population genetic data (COI, ddRAD) of Sialis

Excellent talk by Isabela do O #Biology25, PhD student with @jgx65, showing how population structure can bias Qst-Fst selection tests, and how her new LogAV method can correct and account for population statistics. #PopulationGenetics #MethodsMatter
Excited to read this, I've been worried about the recurrence of these peaks in #PSMC graphs for years. Also, just on time before we submit one (a first for me). #PopulationGenetics #PopulationGenomics #MethodsMatter

Really had to read this article for my current project:
Raynaud et al. 2023 “Performance and limitations of linkage-disequilibrium-based methods for inferring the genomic landscape of recombination and detecting hotspots: a simulation study”

Slightly reassured (but not surprised) to *not* have discovered a mistake in #ANGSD source code.
It's just in the documentation that the formula for the Watterson estimator of theta is wrong.

Intriguing: modeling and empirical data support that after whole genome duplication (autotetraploids) genetic variation rises, and mutation load increases because deleterious mutations are masked by additional chromosome copies

Wolf distribution (Biogeography 🌍)
Wolf distribution is the species distribution of the wolf. Originally, wolves occurred in Eurasia above the 12th parallel north and in North America above the 15th parallel north. However, deliberate human persecution has reduced the species' range to about one-third, because of livestock predation and fear of wol...

“…~ 40% of modern Chinese are patrilineal descendants of only three super-grandfathers at that time. This observation suggests that the main patrilineal expansion in China occurred in the Neolithic Era and might be related to the development of agriculture.” #isogg #dna #populationgenetics #chinese
Reindeer distribution (Biogeography 🌍)
The reindeer is a widespread and numerous species in the northern Holarctic, being present in both tundra and taiga. Originally, the reindeer was found in Scandinavia, eastern Europe, Russia, Mongolia, and northern China north of the 50th latitude. In North America, it was found in Canada, Alaska, an...

Our new #preprint changes the way we look at an “extinction vortex” in which a small population loses fitness, causing it to become even smaller https://www.biorxiv.org/content/10.1101/2024.10.25.620329v1.
