Pine Beetles don’t stick around on slippery bark, says CU-Boulder study

Mountain Pine Beetle

In the online journal Functional Ecology, Doctoral student Scott Ferrenberg and Professor Jeff Mitton of University of Colorado, Boulder describe how they conducted field surveys to determine if mountain pine beetles can successfully attack limber pines with smooth versus rough bark. Scott, who led the study, said he first began to suspect that bark texture might affect the survival of trees while he and Dr. Mitton, a professor of ecology and evolutionary biology, were walking through a stand of high-elevation limber pines. They noticed that surface resin, a residue of fighting off a beetle … [Read more...]
