Abstract

In the last decade, outbreaks of bark beetles in coniferous forests of North America have caused unprecedented tree mortality and economic losses (Nowak et al., 2008; van Mantgem et al., 2009; Waring et al., 2009), converting forests that were previously atmospheric carbon sinks into carbon sources (Kurz et al., 2008). Native species of bark beetle rapidly kill healthy trees by aggregating on their hosts, boring into the stem, and vectoring pathogenic fungi that are tolerant of conifer defenses (Paine et al., 1997; Wang et al., 2013). Climate change is thought to have exacerbatedtree mortality from bark beetle infestations by increasing the number of beetle generations yr–1, expanding the range of beetles and their associated pathogens, and by weakening host defenses (Raffa et al., 2008; Bentz et al., 2010)
