#cepaea — Public Fediverse posts

I work on colourful Cuban snails (Polymita) and European snails (Cepaea). The last person to do that - at least according to Web of Science - was Alex Comfort. Now where do I know that name from?? 🤔🐌🤔👫 #snails #cepaea #polymita

It rains and then this happens. I think I must live near snail heaven. FYI, this is a verge that the local council were persuaded to stop mowing some ~5 years ago. #snails #Cepaea

Snail fans! This photo is a roadside verge that the local council have stopped mowing. On a rainy day, there are so so so many snails (mostly Cepaea nemoralis). You'll need to zoom in to see them. How many? 100, 200 or more per square metre? Incredible.

Of course, now also a sample site for #Genomics #snails #cepaea #springwatch #beeston #nottingham

This summer I'm going to try luring the eastern shell-nesting mason bee (Osmia conjuncta) into my yard. The species occurs in Pennsylvania but is extremely rare, probably because its preferred shell, Anguispira kochi, is presumed to be locally extinct. But Ontario populations of the bee are thriving and seem completely happy to use shells of Cepaea (an invasive from Europe) so I thought I'd give them a try here. Yes, I know this is futile. #bees #osmia #insects #snails #shells #cepaea #pollinators #entomology #ontario #canada

New 🐌 paper, in which we tried to identify qtls that contribute to continuous variation in snail shell colour. While lacking power, short answer is that colour locus is involved, as well as likely other loci elsewhere.

New 🐌 paper alert! We showed that snails with v. few mtDNA copies per nuclear genome (<10) have a v. high rate of heteroplasmy; heteroplasmy is inherited through the germline, albeit with selection against synonymous mutations. We also found that some mtDNA genomes have tRNAs that are repeated up to 24 times! https://doi.org/10.1186/s12864-024-10505-w

Departing MSci student Sam Martin painted this fantastic image for me, two Cepaea nemoralis snails. Not only a promising scientist but also a talented artist #jealous #snails #cepaea

I have frequently heard about the left coiling Cepaea of the Bundoran, Ireland, today I found their shells - many - at the NHM, London 😊. Suspect they were collected to extinction - know anyone willing to take a lookto check?!! #aDNA #snails #cepaea #ireland

I am starting #ArtAdventCalendar with this Eastern Snail Shell Mason Bee (Osmia conjuncta), a small North American blue bee which makes nests in suitable empty snail shells! In my linocut I show this adorable little pollinator with a Cepaea shell. Each print is 8” by 8” on delicate Japanese kozo (or mulberry) paper. I am truly charmed by the idea of a snail shell nest!

Hatchling to adult in five months, the new 🐌 regime is working 😀! Almost an animal 'model'.

Snailing in Prince Edward county, Ontario. Beautiful field site, both species present, and possible hybrids? Also present is 12045 banding phenotype, rare in Europe. #snails #ontario #Cepaea

Hello snail experts and home improvement geeks, does old window putty contain interesting/tasty components like chaulk or minerals?
I got a snail in the bathroom that refuses to go back outside to all the nice natural food options, and insists on eating grey window putty (and producing matching grey poop). I moved it outside yesterday but it was back this morning.

Happened upon a rare Cepaea on way home last night, missing the middle band ('12045') - last time I found one like this, it turned out to be a hybrid #cepaea #snails #hybrid #Speciation #speciationgenomics

First time I have spotted Cepaea hortensis on the University campus - and it's a beauty. Benefits of walking to work on a drizzly morning

It's raining and now there are four snails sitting/hanging in my dead basil shrub, having a snack while looking funny 🐌

SHOW2023 - short for Simultaneously Hermaphroditic Organisms Workshop - was hybrid last week @vuamsterdam (co-organised with @YumiNakadera) and contained great presentations, useful discussion sessions, a wonderful boat dinner (Smidtje), and a lovely, ethically produced 100% natural cotton bag for participants. Next year: SHOW2024, Rennes (France) @steve_ramm

Dark lipped Cepaea nemoralis (on left) and pale-lipped Cepaea hortensis, yeah? No - both are C. nemoralis! See reply to see how they looked a couple of days later.

Lip colour and size is the conventional way to identify the two species, but it does not always work, especially in some regions (Cornwall, UK; Pyrenees, Spain), and depending upon age. There are also a lot of snails labelled "C. hortensis" on #iNaturalist that are more likely C. nemoralis. #snails #snail #cepaea

Here’s my #printerSolstice @printerSolstice #linocut for the prompt “texture”. The Eastern Snail Shell Mason Bee (Osmia conjuncta) is a small North American blue bee which makes nests in suitable empty snail shells! In my linocut I show this adorable little pollinator with a Cepaea shell. Each print is 8” by 8” on delicate Japanese kozo (or mulberry) paper.

My snail ID'ing skills coming to the fore on iNaturalist today - roadkill snail in New York, certainly introduced Cepaea, most likely C. nemoralis #iNaturalist #Cepaea #snail #roadkill

Mid-November and there are still colour polymorphic Cepaea nemoralis (grove snail) out and active in the UK; worldwide #iNaturalist records by month on right.

#UoN #BBSRC PhD student Margarethe Johansen will present an update (based on whole genome linkage map) in our quest to identify the colour and banding loci, this Thursday at #MolluscanForum #NHMLondon. Free registration, hybrid event [email protected] #Cepaea #grovesnail #Evolution #Polymorphism
