Somewhat bewildering that a city the size of #nyc doesn't have a #phylogenetics workshop or such. Not a ton of classes open for auditing either, though I'm hoping to find something soon :-/

How many species can you use in a full multi-species coalescent tree inference such as BPP or Star-Beast ?
Also, does it work well for old divergences (like hundreds of millions of years)?
In Xu & Yang 2016, they say:
> Furthermore, current Bayesian implementations do not deal with the violation of the molecular clock adequately and do not appear to work very well for deep species phylogenies (Ogilvie et al. 2016)
But since then, has it improved?

Day 2 of #ICAM2023: packed with great presentations on the taxonomy and speciation of coralline algae!
TLDR: wherever you go in the world, there are many more coralline species than we thought!

Simulations of sequence evolution: how (un)realistic they really are and why
"Our findings suggest that the current state-of-the-art models fail to accurately replicate the process of evolution."

Reading this preprint: Simulations of sequence evolution: how (un)realistic they really are and why

Surprisingly the complex mixture models (e.g. C60) are more distinguishable from real data the simpler models. They note that it may be due to the trees they used for simulation, which have branch lengths inferred without the mixture models.
The top feature that distinguishes empirical from simulated alignment is the randomness of the rate-across-sites.
How to build a summary phylogenetic tree from a MCMC sample?
There are many different ways: Majority Rule, Maximum Clade Credibility, etc.
I thought these notes to myself were worth sharing here:

I signed up for this site last year so it’s about time I actually started using it! A bit of an #introduction. I am an #ornithologist who works on #phylogenetics #taxonomy and #macroevolution. These days mostly with #suboscine birds. I love working with and contributing to citizen/community science databases like #iNaturalist and #eBird. Follow along for wildlife photography and science content!
