Duckweeds (Lemna minor sensu lato) cover the surface of the upper region of Mill Pond in Durham, NH, together with closely related species (Wolffia sp. and Spirodela polyrhiza). Duckweeds in this region exhibited weak local adaptation to biotic (microbiome) and abiotic (water) features of their environment combined.

Observing weak adaptation of #duckweeds to their local microbiome depends on local pondwater

ASPT is excited to launch a five-part special webinar series, “Taxonomy: What is it good for?”, spotlighting voices from the global plant taxonomy community and the real-world impact of systematic research. We kick things off Friday, February 6 at 12 PM ET with Sandra Knapp (Natural History Museum, London). Her talk, “Of course taxonomy matters! The story of the mega-genus Solanum (Solanaceae)” . . . dives into one of the largest and most fascinating plant genera on Earth—and shows why taxonomy is absolutely essential to science, conservation, and society. Registration is free.

Almost lost amidst the cow excitement (cow-motion?) was that @currentbiology.bsky.social featured a brilliant paper on #lichen fungi in this week’s issue by Victoria Keller et al. including @veera-t-nogerius.bsky.social — what is not to lichen about this new double ascomycete living arrangement

Hooray! Check out this special issue for some fantastic new work on flower color!

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!

Just published! A terrific special issue in #AJB #SocietyJournal #FlowerColor

Photo of a green tree trunk with numerous big spines. A sign on the tree gives the name in Arabic, Latin ("Chorisia speciosa") and English ("floss silk tree"), the family (Malvaceae/Bombaceae") and the origin ("Brazil, No. Argentina"). Note that the latin name is now Ceiba speciosa instead of Chorisia speciosa.
