good morning. I strongly suspect that we don't really know (or agree) what geographic ranges are, and therefore, our estimates of how species' ranges are shifting in the Anthropocene are uninterpretable. I wrote something about this: doi.org/10.1111/2041... and I'll share the main findings...

Measuring the edges of species' geographic ranges
The fundamental unit of spatial ecology is a species range: the geographical area that it occupies. Species ranges are delineated by range edges (also known as boundaries or limits). Why range edg...
