Thank you WPC. "Sheila Colla was widely admired. She was far more than a brilliant scientist and conservation leader. She was a fierce advocate for environmental and social justice and was incredibly skilled and determined at bridging the gap between science, community, and politics."

I work at a public library. People who want to use AI seem to have no trouble doing so. People who don't want to use AI have a harder time. I crowdsourced and then finalized this document "How to disable or avoid intrusive AI" and then gave it a short URL: notoai.org Please pass along if it's useful

AI, Comparative Advantage, and the Next Decade of Ecological Research. Food for thought @jdrakephd.bsky.social doi.org/10.1111/ele.... #ecopubs
For the past two decades, the message to young ecologists has been consistent: learn to code, learn statistics, learn machine learning, learn ‘modelling’ (GIS, differential equations, species distribution modelling, etc.). That message was correct and remains so. But it is incomplete. The researchers who will hold a durable comparative advantage in the decades ahead may be those who invested in the patient, expensive, logistically difficult work of building field programs, maintaining experimental infrastructure and cultivating the expertise required to collect data that no one else can collect.
