264 - Could changes in pesticide hazard to bees be detected across a state?

Bees are exposed to pesticide hazards in a variety of ways. Estimating how hazards to bees are changing over time, across an area as large as a state, is a daunting prospect. This week we hear about an attempt to estimate changes in hazards in a new paper by Dr. Emily Carlson, a recent PhD student from Oregon State University.
