Preparing to leave twitter/X. I've moved to blue sky - @dlfield.bsky.social

My entire team wrote an opinion paper about Common misconceptions of speciation research. Each section is written by 1-2 team members. The bulk of the writing happened during two writing retreats. It was a lot of fun and I am very happy with the result. academic.oup.com/evolinnean/art…

That's Not a Hybrid: How to Distinguish Patterns of Admixture and Isolation By Distance | Molecular Ecology Resources onlinelibrary.wiley.com/doi/10.1111/17… Very important paper! Indeed, I have also noticed that Structure/Admixture plots are often overinterpreted as introgression.

@waspwench @PlantPolyploidy Maybe some hybrids. I've seen tall chrysanthus with humilis coloured flowers too

@dfield007 @PlantPolyploidy The individuals we noted all sat close to the ground as per the standard humilis. Interesting! Most images of chrysanthus show quite a tall plant in comparison. Short populations of chrysanthus perhaps…

#Anigozanthos humilis (#catspaw) rocking a bright yellow pigment out near Muchea! Populations out here are a lot more yellow than Perth. Such variation in colour! @PlantPolyploidy look! #Haemodoraceae #wildoz #native #flora #pollinationecology #yellow #swancoastalplain #fuzz

@waspwench @PlantPolyploidy Nice find! It does look like subspecies crysanthus. If it's also taller than standard humilis then quite likely. There are records of chrysanthus nearby west of Chittering

@PlantPolyploidy @dfield007 An official floristic survey for the site lists humilis subsp. humilis, A. manglesii subsp. manglesii, & an unspecified Anigozanthos sp… Style length & setting highly variable across individuals too which was fun to see, particularly from a pollination success perspective.

@nicrodemo @ibc2024 @thebuzzbus The Buzzbus strikes back!

@dfield007 @ibc2024 @thebuzzbus Thank you David! Time to plan the next field expedition!

Excellent talk by Mario on buzz pollination at @ibc2024 and featuring the @thebuzzbus

Want to do a PhD on why buzz pollination evolves? I will be recruiting a PhD student this Autumn (4 years, fully funded). The official ad will come at the end of summer. if you are interested in the studentship please email me so I can send you the full ad when available.

@waspwench @nicrodemo @NatGeoExplorers @HFSP @LeverhulmeTrust @plant_ecology @PlantEcoEvo_UU Thanks for the enthusiasm on the buzz bus paper. Let us know what you find out regarding Calectasia narrragara. Sounds like a fun sleuthing expedition.

@nicrodemo @NatGeoExplorers @HFSP @LeverhulmeTrust @plant_ecology @dfield007 @PlantEcoEvo_UU Fantastic stuff! Can't wait to sit down with a hot coffee for a decent read! We will be playing with Calectasia narragara this upcoming flowering season to find out who is buzzing those beautifully erect poricidal anthers! Buzz pollination is such a fun field 🥳

Fieldwork is one of my favourite parts of science. For this paper, I had the chance to travel with wonderful people in Mexico, Scotland and Australia studying how different bees buzz. Thanks to @NatGeoExplorers, @HFSP, @LeverhulmeTrust and everyone! doi.org/10.1242/jeb.24…

@ssrdjann But no lion cows this year 😆

@dfield007 Wait, not only did you find anthirrhinum down under, but you built them the Pyrenees! 😁

Hello again beautiful snapdragons. Pictured, typical magenta pigmented Antirrhinum majus pseudomajus. Field work in the Pyrenees, a stunning place for biologists and old fashioned botanising.

Power nap room! What a great idea to officialise resting the brain briefly before tackling the next research challenge. All universities should consider such a setup

Back to old research stomping grounds of Austria and Vienna.

@TiBoLeroyInEn Totally addicted to base R 😀
