Very large snail in hand

Baby snail, less than a month old

Field work in one of the smallest countries, Sao Tome, looking for one of the largest snails, unfortunately also endangered. Success! Giant Obo snail 🐌, bigger than your regular Giant African land snail - and sinistral coiling. Just born baby = garden snail size 😮 #snails #saotome #chirality

I need to insure a snail shell - the remains of "Jeremy the shellebrity snail" - for international travel. It is going to be the centrepoint of Netherlands museum exhibit! But what value do I put on a one in million snail?! #snail #snaillove

"With free bar stocked with local beer" I think I meant 🍺

I've been sitting on this for over a month...but given how cross I am with @royalsociety.org at their ongoing inaction over #Elon #Musk I thought I'd share this.

They invited me to serve on their Public Engagement Committee; I could have been more eloquent, but I had to give a firm "no"...

And if you want a list of the reasons that have been given for keeping Musk as FRS, there's this piece deevybee.blogspot.com/2025/02/seve...

Reporting back from the frontline of the 59th iteration of PopGroup conference in Lille, only the 2nd ever outside the UK. With a free bar stocked with local bar, excellent frites for the poster session and top quality food, why would we ever hold it anywhere again?! 😁 #pgg59 #popgroup59 #conference

Evolutionary dynamics of dietary specialisation – insights from Neotropical mistletoe‐dependent frugivores Mistletoes occur worldwide, with most relying on birds to disperse their sticky seeds to suitable hosts. There has been considerable ecological research on these interactions, emphasizing those birds....

In time for the festive season, my latest paper charts the 25 million year story of how mistletoe and songbirds somersaulted across the Americas, diversifying as they went.  Strap in for an epic ecological tale #MistletoeMunchersFromWayBack 1/12

Apparently "Nottingham has evolved into one of the largest university estates in the country ..." Blame "evolution", not themselves, eh? No apologies, of course, but at least they are selling Castle Meadow, which has cost nearly £100m and is not fit for purpose. At a huge loss, of course. #UoN

UCU union demo outside university of Nottingham building. Lots of pink!

Two days of demos and inspirational speeches outside Trent building - while university council decide our future but without our consultation, or consideration of the local and East Midlands community. #UoN promotes #WeAreUoN hashtag but does not listen. #University #eastmidlands @ucu.org.uk

I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

Image shows planned course closures in the Faculty of Arts, including the whole of modern languages and music. This will inevitably lead to closure of the whole departments and multiple job losses

BREAKING The University of Nottingham has decided to lead the way in being the first 🥇 Russell group university to NOT do modern languages. Music is also gone! 🗡️ Apparently, neither are necessary for a world "top 100" university with charitable status. ENDS

Right. Hitler's DNA. Brace yourselves for a deluge of misinformation and bad science.

I'm in Australia, so do get in touch if you want some expert debunking.

The snail farmer of London, his mafia friends, and a £20m vendetta against the taxman Terry Ball runs elaborate mollusc-based tax avoidance schemes that are costing London councils millions of pounds. Yet when London Centric tracks him down, an even stranger story emerges.

How does a single cuckoo species evolve eggs that mimic those of many different hosts?

In a new Science study, researchers report genomic data that reveal a complex geographic mosaic of cuckoo-host coevolution.
