@romanzug.bsky.social and @socialinsectlab.bsky.social thinking about colony dynamics! Resource variation can mask tradeoffs, but here we show that even if that *doesn't* vary, lucky starts in colony life can lead to better trajectories and if so, a tradeoff is often undetectable despite being real.

Mesocosm experiments and lab-based digestive assays reveal that selection on digestive physiology can buffer organisms against putative costs of predator avoidance, demonstrating how trait networks can decouple growth from predation risk in complex ecological systems:

Cheating death: selection on digestive physiology overcomes expected growth costs of antipredator defences

Abstract. Organisms often face a fundamental trade-off between growth and predator avoidance, where traits that enhance growth—such as higher activity rate

How do light and noise pollution impact selection on sexual signals? We tested mate attraction and bat predation on túngara frogs. Light and noise interact in complex ways, and light pollution shifts selection on male calling:

We show evidence of de novo genes emerging from the Nucleosome Depleted Regions (NDRs) of yeast genomes. They are biased towards encoding transmembrane domains because of the NDRs too!
