Thrilled to share this pre-print from an exciting collaboration with @bnashby.bsky.social, @asherleeks.bsky.social and @bramvandijk.bsky.social! Viral cheats that emerge through social evolution, under vertical transmission as proviruses, become defense systems to their hosts.

New preprint from our lab, with @sultannazir.bsky.social! 🚨 Defense systems in pro- and eukaryotes are often derived from the very parasites they now defend against. Here we show how this all starts with the emergence of cheaters in parasite populations! www.biorxiv.org/content/10.6...

I'm excited to share that my first paper is finally out and about! We unpack how the resource cost of traits varies across environments. I did this work during my MSc at UBC @ubcbiodiversity.bsky.social, @zoology.ubc.ca. I'm grateful for all I learned from @sarperotto.bsky.social in this journey.

Physiological trade-offs make traits costly, but resource requirements vary. This study by @sarperotto.bsky.social @javadmeghrazi.bsky.social &co uses a unified energy-proteome allocation framework to predict costs and growth across environmental conditions. 🧪 #AcademicSky plos.io/4k5TlUA

The effect of environmental quality on the cost of traits.
The effect of altering provisioning efficiency (e.g., by food quality, panel a) and biosynthesis efficiency (e.g., by antibiotics that inhibit ribosomes, panel b) on the cost of different categories of traits (points I–IV). Panel c shows the relationship between the birth rate and the increase in allocation of macromolecules or energy to a trait.
