There’s a new paper reporting on major bee declines that has been picked up by the media: cell.com/one-earth/full…

I don't think the results of that paper are robust.

Feel free to follow along my meandering, largely anecdotal exploration of some of the data. 1/ The paper reports declines after 1990 and big declines after 2005.

My first thought on reading is that the observed pattern is likely due to the lack of taxonomists and taxonomic bottleneck. I examined the data a little deeper, and I think what I found supports my hypothesis. 2/

Omg these methods: “We treated beehives with permethrin by shooting them with a crossbow bolt that distributed the compound upon impact.“

There’s even a picture!!! 🏹🐝!! From “Experimental removal of invasive Africanized honey bees increased breeding population size of the endangered Lear's macaw”
