(🧵 1/3) Evolution of petal patterning: blooming floral diversity at the microscale

Fig.3 Micropatterns on the petal surface are created by variation in epidermal cell pigment, shape and cuticle textures.

New research from my lab @newphyt.bsky.social! Using the plant family #Melastomataceae, we show that colonization of novel #mountain environments commonly preceded and likely drove #pollinator shifts away from bee pollination! doi.org/10.1111/nph....

Thank you @botsocamerica.bsky.social for featuring our research! We had a great, scientifically stimulating review experience at AJB, thanks to the editor and reviewers! And guess what - the global distribution of #flower and #fruit #colors shows strong links with temperature and UV-B irradiance!

Does the abiotic environment influence the distribution of flower and fruit colors?

A four-part figure showing marked differences in flower and fruit color composition between tropical and temperate environments. (A, B) In flowers, white (grey on map) is the dominant color across environments (summarized here as biomes), but the mostly anthocyanin-based colors red and pink are increasingly common at higher latitudes, while yellow and purple are more common in arid grasslands both in the tropics and temperate zone. (C, D) In fruits, red and black are the most common colors, with red becoming particularly dominant at higher latitudes, while tropical biomes show a more even distribution of all fruit colors; yellow fruits are more common in arid grasslands.

Thinking about devastating cuts to NSF: US gov-funded science has been the engine upon which most of the tech wealth was generated. But the oligarchs (currently hoarding much of that $) think it’s their own brilliance & not the accident of standing close to the scientific engine that made them rich.

I couldn't be reading a more inspiring paper after spending a month in the rainforests of Madagascar and Borneo training students on #Melastomataceae reproductive biology: doi.org/10.3417/2025...

Ep. 2 of Plant People Season 2 is LIVE—and this week we’re talking something that’s on everyone’s radar: food. 🎧🍎

Join @alexmcalvay.bsky.social and John de la Parra as they chat about problems in modern agriculture (like monocrops!) that are threatening food security. www.nybg.org/plantpeople/...

Good news, Altmetric has now started watching BlueSky for mentions of publications. And by the way, provides an easy comparison between this and the old site for a recent preprint of mine which I posted simultaneousl at both. Numbers speak by themselves !

Hopefully this gets people thinking about the origins of life's thermal optimisation. I'm also super excited about this study - it's probably one of the most "stretchy" projects I've ever worked on, but great fun!

Excited about our new paper asking: Why does the growth of most life have an optimal temperature below 40°C? We argue the average maximum oceanic temperatures of <37°C for 2+ billion years drove evolution of the temperature optima of prokaryotes. 1/5

Earth's Climate History Explains Life's Temperature Optima
We propose that the origin of the temperature optima of life results from two discrete evolutionary selection pressures that constrained the evolution of fundamental biochemistry and growth of most l...
