Dartmouth research offers new control strategies for bipolar bark beetles
Date:1/25/2013

gnals, that attract enough competitors and predators to prevent outbreaks," says Sharon Martinson, a member of the research team and first author on the new paper. "Leaving more dead trees in forests can provide habitat for competitor beetles that rarely kill tree, and for predators that eat both beetle species."

The authors suggest that other pest species with catastrophic impacts may also have natural dynamics that include a tipping point between the bipolar population states. By learning what factors control those tipping points, impacts on ecosystems can be averted through monitoring and occasional intervention strategies.
