Mountain Pine Beetles Use Volatile Cues to Locate Host Limber Pine and Avoid Non-Host Great Basin Bristlecone Pine
Fig 1
Photographs of limber pine (Pinus flexilis) and Great Basin bristlecone pine (Pinus longaeva) forests (a) on Cave Mountain in east-central Nevada, and (b) in the Spring Mountains in southern Nevada.
These tree species co-occur in nearly equal abundance on and near the top of Cave Mountain (a), the dead trees (gray trees) are mountain pine beetle-killed limber pine. In the Spring Mountains (b), these tree species co-occur below dashed line, note many dead limber pine trees (gray trees), but a nearly pure stand of un-attacked bristlecone pine occurs above the dashed line.
