Mario Coiro @lepidodendron.bsky.social · Mar 22
last week my latest paper on #cycads came out.
The article deals with the idea of cycads as "living #fossils", but what does this mean exactly, and what did we actually test? A thread for #FossilFriday!

Disparity of cycad leaves dispels the living fossil metaphor - Communications Biology
An analysis of leaf disparity through time in cycads shows that this group has a dynamic and expanding morphological diversity until the present, and thus does not fit the ‘living fossil’ hypothesis o...

Hello from Stuttgart! Never been to the SMNS before but it's a lovely museum with amazing collections. Right now they have a temporary exhibit on Triassic life, featuring Mirasaura. @stephanspiekman.bsky.social showed me round.. Amazing fossils!

New paper showing clustering of the many traits across reproductive strategies of angiosperms. Lots of interesting discussions that gave raise to this piece. But only possible thanks to the hard work of Andrew Helmstetter, Sylvain Glémin, and Jos Käfer.

An angiosperm‐wide perspective on reproductive strategies and floral traits
Flowering plants have many modes of sexual reproduction, notably varying from selfing to outcrossing, and from bisexual flowers to individuals with separate sexes (dioecy). These reproductive modes ...

The USA can withdraw from @ipbes.net but, IPBES Chair @davidobura.bsky.social observes, “unfortunately, we cannot withdraw from the fact that more than 1 million species of plants and animals face extinction.” 😞😠

“We cannot withdraw from the fact that over 1 million species of plants and animals face extinction.”

IPBES remains committed to its mandate to provide the most credible science and evidence about biodiversity to all decision makers and actors.

Left side contains a statement from Dr David Obura, IPBES Chair, regarding the US withdrawal from IPBES and extinction threats to over 1 million species. Right side shows a photograph of a man wearing glasses, dressed in a dark jacket and grey shirt, seated at a conference table with a microphone. The IPBES logo appears at the bottom with the tagline "Science and Policy for People and Nature". The design features white typography on the dark green background, creating a professional contrast. Several small pins or badges are visible on the speaker's jacket.

I'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢

I love that the online copy for Tyrant Lizard Queen says “from the author of the beloved The Last Days of the Dinosaurs” right at the top. I think it is, which is pretty amazing for a story about one of the worst times on our planet.

Zamia spp. is the host plant for Eumaeus atala caterpillars. Both larvae & adults are aposematic. Zamia contains cycasin, a carcinogenic & neurotoxic glucoside. This toxin is not to be trifled with! 📷: larvae by Judy Gallagher CCBY2 #Zamiaceae #Aposematism #Botany 🌾🧪🌱
