As botanists and Plant Architects in Montpellier 🌿, his vision of forests 🌳 profoundly shaped the way we think about and observe plants. A giant has passed, but his legacy will remain a major source of inspiration, worthy of our deepest admiration and gratitude.

Lobbyist Claims Monsanto's Roundup Is Safe To Drink, Freaks Out When Offered A Glass
YouTube video by Panteralandia Lobbyist Claims Monsanto's Roundup Is Safe To Drink, Freaks Out When Offered A Glass

This is worth watching. It reminds me of the claim that DDT was "so safe you could drink it." Yet another example of industry recycling refuted claims. @kaurov.org @michaelscherer.bsky.social @davidho.bsky.social

Who Identified the Plants? Reclaiming Plant Identification Expertise in Vegetation Science This article advocates for the formal recognition of botanists who identify plants in scientific publishing, highlighting their essential role in ecological research and data integrity. It proposes p...

🌿My two (botanical)-centsπŸ”

In this forum paper, I reflect on the value of plant-identification expertise and offer a few ideas on how we can better highlight the role of botanists and their knowledge.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.

Very happy. A paper just out of the oven. It is a piece of work made possible only after many years of thinking about, and looking at, an old problem from multiple perspectives. And with the magical brushstrokes of our artists, Gabriela and Ariadna.

Hidden in the tar are fossils too small to see with the naked eye: pollen grains.

These microscopic time capsules preserve clues about Ice Age landscapes, revealing what plants grew in ancient L.A. and how ecosystems shifted over thousands of years.

In fact it wasn't entirely correct (it neglected two relevant genera). As you say, there is a space in which LLMs are very useful: where they extend the users's knowledge. But, also as you say, they are merely dangerous where they are asked to satisfy a user's wholesale lack of knowledge

an extract from a 'conversation' with ChatGPT 5.1 about plausible botanical source genera for a lowland Borneo fossil pollen type identified in a published fossil pollen publication as "Prunus". The final sentence is the most impressive/disturbing, the unprompted 'observation' that introuced taxa needn't be considered unless the sediment is geologically very young

Yep, LLMs make unbridled demands on power/water & are mega-plagiarism; but it's also useful to monitor where this is going. I have to admit to being surprised by ChatGPT's ability to generate appropriate criteria for evaluating plausible botanical source taxa for fossil 'Prunus' in lowland Borneo

This is horrific and exactly what those of us in Black studies, gender studies, women’s studies have been warning our colleagues in the sciences about. Their seeming neutrality will not save them.
