Are plant–pollinator interactions more specialised in the tropics? After almost 25 years of thinking about this question, our new global analysis suggests there’s no simple latitudinal rule - it all depends! Read about it here: jeffollerton.co.uk/2026/10/01/a... #pollinators #ecology #biodiversity

An outstanding review of the myriad ways insects are central to vertebrate survival. They appropriately call attention to how much we still don't know about these interactions and how to conserve them, but avoid (intentionally?) calling attention to the fact that we are included in 'vertebrates'!

This point needs to be made over and again: The main purpose of wealth taxes should not be to raise revenue. That's a small and secondary benefit. The main purpose should be to *reduce the fortunes of the ultrarich*. Why? Because those fortunes present a massive threat to democracy and public life.
