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.
