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 protect and recover populations now - see forecast www.biorxiv.org/content/10.1...

Genetic diversity loss in the Anthropocene will continue long after habitat destruction ends

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). H...

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 population size (reviewed datasets published in the last decades generally cover short timescales, median ~7 years).

Moi Expósito-Alonso (MOILAB) @mexpositoalonso.bsky.social · Aug 4

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

Many news outlets picked this up like The Guardian, World Economic Forum, etc:

Study of more than 600 animal and plant species finds genetic diversity has declined globally

Analysis by dozens of scientists internationally notes urgent conservation efforts could halt or even reverse losses

New research from Priya Moorjani's lab offers insights into India’s genomic legacy.

Postdocs @lauritsskov.bsky.social and @ekerdoncuff.bsky.social traced Indian's ancestry to three main sources. Read the findings in this story by grad student Jules Perez: bit.ly/3IK46vh
