We're trying to understand why.
If you work in community ecology, we'd really appreciate your input in a quick survey (<5 mins).

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

Getting excited for #CSEE2025!
On Wed morning I’m organizing (& talking in) a symposium - along with Zach Miller and Maxime Clenet - that will bridge theoretical and empirical approaches to understanding spatial and temporal dynamics.
Then @sweeet-ecoevo.bsky.social symposium in the afternoon! 🙌
