“It’s like claiming to have brought Napoleon back from the dead by asking a short French man to wear his hat.”
A short piece in The Conversation by me on why “de-extinction” is nothing of the sort, and bad, bad conservation.

New paper - England’s Biodiversity Net Gain policy could easily and inadvertently harm invertebrate populations because it doesn’t value habitats, condition, connectivity, or scale in ways that invertebrate populations respond positively to.

I’ll happily die on the hill of academic freedom of speech. But I’m damned if I’m sharing it with the Oxford Union who have absolutely nothing to do with it.

Just breaking my own Twitter embargo to congratulate @johnmittermeier and colleagues on refinding Otidiphaps insularis after 146 years, and also on outrunning pirates. We need to adjust the postgraduate research skills training accordingly :) https://www.bbc.co.uk/news/world-asia-63672501

The perfect time for the government to spend a zombie month while the Brexit ultras try a last power grab and we all pay. “…my lifeless two-year-old wasn't enough of an emergency to get the help of the ambulances. The cuts to the NHS are just so scary.” https://www.bbc.co.uk/news/uk-wales-633256...

I spent the summer off Twitter, pretty much. I’ve returned to it this week. And honestly, I think I need to fundamentally rethink whether and how I use it. I’ve curated my feed intensively, and professionally and politically it tells me a lot of things I want and need to know.

Amazing-looking paper in Nature on the new @IUCN ecosystem typology. It’s a hugely ambitious idea, with profound and quite hard-to-predict consequences for monitoring: https://www.nature.com/articles/s41586-022-05318-4 Itâ��s also got an eye-opening (presumed) response to a reviewer…

Yes, a screenshot of a retweet. But the UN just retweeted to the world a warning from major conservation bodies about the Conservatives’ plan to destroy three fundamental legislative pillars of nature protection in the U.K. without clear replacement. It’s bad on a global scale.

Is there a name for assorted digital cruft that builds up in your life but to which you are strangely attached? One of my accounts still gets promotional mails from a limo company I used once in NYC in 2004. I was even worried about them during lockdown.
