Yes - isometric scaling as a way to understand the benefits and costs of being small versus large. Haldane's Harpers article from 1926 is an amazing example of popular science writing.

This looks to be a fundamental theoretical advance by @jpodwyer.bsky.social et al. Using linkage disequlibrium-based Ne to back out σ² and then predict fluctuation sizes from a single temporal snapshot is a real advance for broad application 🧪🌐https://www.science.org/doi/10.1126/science.adu6396

Species population sizes fluctuate over time, and these temporal dynamics play a key role in governing the maintenance of biodiversity. Although modeling approaches have been developed to characterize...

New review out! With students in my lab, we explore how population size shapes speciation—from drift in small populations to selection in large ones. Do small or large populations speciate faster? The answer is more nuanced than you might think.
