Growth and survival before and after a mountain pine beetle outbreak in a ponderosa pine genetic trial

Datasets Posted on: March 15, 2018
This data package contains data used for the publication "An insect outbreak shifts the direction of selection from fast to slow growth rates in the long-lived conifer Pinus ponderosa" (de la Mata et al. 2017). The study includes measurements from 204 half-sibling families planted in a common garden experiment planted in 1974 and last measured in 2013.

Insect outbreak shifts the direction of selection from fast to slow growth rates in the long-lived conifer Pinus ponderosa

Publications Posted on: July 19, 2017
Long generation times limit species' rapid evolution to changing environments. Trees provide critical global ecosystem services, but are under increasing risk of mortality because of climate change-mediated disturbances, such as insect outbreaks. The extent to which disturbance changes the dynamics and strength of selection is unknown, but has important implications on the evolutionary potential of tree populations.
