Reading that report, a question comes to mind, the talk at length about the bees range moving in the area of 400KM over a 10 year period.. it seems to me that it would take a larger period than that?? Assuming a flight range of as much as 5 miles, wouldn't it take a lot longer than 10 years to see a 400km shift?? Seems to me sample errors are a better explanation?
Realistically how much range change would you expect from a bee? Most make their nest within 3 miles of where they were born from my understanding.
