To promote the collection, I’ve launched a designer clothing line where synthetic biology meets aesthetics. I will give out 100 free limited edition shirts to the first who retweet and order with their handle in the name! Available here → https://t.co/KctFUBPZQH 🧵(6/7)

I want to thank Shaw et al. and corresponding author Prof. Grueber for their enormous effort in compiling genetic data from across the literature, for their thoughtful analyses, and for their engagement in correspondence regarding my inquiries. And many colleagues for feedback

Crucially, the lack of signal in my re-analyses does not mean genetic diversity is safe. Evolutionary theory also predicts an enormous genetic diversity extinction debt. To prevent future irreversible losses we must recover populations now - see forecast

Genetic diversity within species is the basis for evolutionary adaptive capacity and has recently been included as a target for protection in the United Nations’ Global Biodiversity Framework (GBF)....

Genetic diversity is likely declining globally, but evolutionary models predict small percentage losses are expected at short timescales, unless a species has truly plummeted in pop size (reviewed datasets published in the last decades generally cover short timescales, ~7 yrs).

Conservation policy typically speaks in terms of % diversity loss. I therefore attempted to translate the study’s reported effect sizes meta-regression, but found the percent changes to be close to ~0%, with half species decreasing, half species increasing in genetic diversity.

Earlier this year a very large review of genetic diversity trends within populations of >600 species was published in Nature, reporting a consistent significant genetic diversity decline across species. https://t.co/SALNYhL5fr

Amazingly thankful to https://t.co/xQ7CcuCSMn consortium who persevered for years to run the experiments! And dream team Xing Wu and Tati Bellagio for final analyses/writing, Meixi and Lucas for comp. analyses, Ru Peng for enormous data, and +++ others! https://t.co/LXQVyPisQ1

Climate change is threatening species with extinction, and rapid evolutionary adaptation may be their only option for population rescue over short ecological timescales. However, direct observations...

Our big dataset let us to test whether evolution in a novel environments was predictable from the rest of the data We found early warning signals to anticipate if populations will adapt and persist or not – important lessons to incorporate evolution to biodiversity forecasts!

We tested whether such gene trajectories could have been predicted – we found genetic variants from warm regions of the species, increased in frequency in experimental evolution plots in warm outdoor locations, allowing us to build models
