by PhD student Swapna Subramanian. Wild yeasts on apple orchards in CT exhibit local adaptation (and sometimes maladaptation) to their particular orchard & apple variety. The dominant yeast's adaptation affects community composition
Local adaptation shapes community composition without affecting performance
Eco-evolutionary theory predicts that local adaptation should influence community assembly and performance, yet empirical tests of these predictions remain limited, particularly at microgeographic sca...

It's finally out! This paper took quite a while but I'm so excited to share now! For anyone who studies sex chromosomes, take note: we found a rare "slower X"! (dN/dS_X < dN/dS_Autos) 👀
New paper: "Faster adaptation but slower divergence of X chromosomes under paternal genome elimination" (Open Access)

Faster adaptation but slower divergence of X chromosomes under paternal genome elimination - Nature Communications
X chromosomes evolve faster than autosomes, but confounding factors make this a difficult phenomenon to study. Utilising the unusual sex determination system of Sciaridae flies, this study finds a slo...

Learning the language of viral evolution and escape
Language models of influenza hemagglutinin, HIV Env, and SARS-CoV-2 spike viral protein sequences can accurately predict viral escape patterns.

Pathogen genomes can provide insights into underlying disease transmission patterns but new methods are needed to analyze large genome datasets. Our work using identical pathogen sequences to characterize fine scale SARS-CoV-2 transmission was just published in @nature.com tinyurl.com/bdzk9xjj 🥳
Fine-scale patterns of SARS-CoV-2 spread from identical pathogen sequences - Nature
The analysis of pairs of identical SARS-CoV-2 genome sequences enables characterization of transmission patterns between geographies and age groups.

Experimental evolution of evolvability
Evolvability—the capacity to generate adaptive variation—is a trait that can itself evolve through natural selection. However, the idea that mutation can become biased toward adaptive outcomes remains...

How about parasitology ?
The concept of the “extinction of experience” has been used to describe the dwindling human connection with nature, often applied to the general public.
But ecologists themselves are not immune. Across universities and research institutions, field-based studies are in retreat.

Resistance to one antibiotic can make bacteria resistant or sensitive to another antibiotic, opening paths for combinatorial treatments. A study in Nature Microbiology presents an approach to systematically discover and understand such antibiotic relationships. https://go.nature.com/49of3Mk 🧪
