Do you think you understand effective population size (Ne)? This key concept for conservation is complex.. but a new Special Issue organized by @jmergeay.bsky.social et al. provides clarity with 19 papers help us understand more 🧬

A must read for conservation geneticists on the utility (or not??) of using molecular diversity to predict adaptive potential 👇🏻
I'm excited to share that our preprint is now available on bioRxiv! Our study challenges the widespread use of molecular genetic diversity as a predictor adaptive potential, with important implications for how genetic data is used to inform conservation decisions.

Nucleotide diversity is a poor predictor of short-term adaptive potential
A capacity to adapt is essential for a population to avoid extinction in a changing world and is recognised as a global conservation priority. Adaptation requires additive (heritable) genetic variatio...

Dear US researchers: break the outrage addiction. I survived the besieging of science. So can you.
