Thank you. I would like to clarify, when using site-heterogeneous models like C10/20, sites are already modeled with the frequency profile, does it make sense to additionally apply +F for empirical AA frequencies from the alignment? And do you recommend using it for single gene phylogenies?

Wow. Foraminifera!

ROV pilots paused and carefully zoomed in to collect footage of these single-celled microorganisms, or protists, at 843 m during the #OBVI #LivingBioreactors expedition w/ @schmidtsciences.bsky.social offshore of Argentina. Read the full caption: youtube.com/shorts/Yv_ud...

A Practical Approach to Study Uncultivated Protists Using Single‐Cell Techniques for Electron Microscopy Protists represent a significant portion of eukaryotic diversity with a wide range of ecological roles, lifestyles, and diverse morphological traits. Despite their widespread importance in ecological....
