Engelmann Spruce Survival and Regeneration After an Epidemic Spruce Beetle Outbreak on the Markagunt Plateau in Southern Utah

Jessika M. Pettit

Bark beetle outbreaks are becoming more intense and severe when coupled with the effects of climate change. Engelmann spruce (Picea engelmannii) is one such species facing large-scale, epidemic spruce beetle outbreaks. Large-scale disturbances, such as beetle outbreaks, have major consequences for the …

Spruce beetle outbreak was not driven by drought stress: Evidence from a tree‐ring iso‐demographic approach indicates temperatures were more important

Jessika M. Pettit, Steven L. Voelker, R. Justin DeRose, Julia I. Burton

Abstract Climate change has amplified eruptive bark beetle outbreaks over recent decades, including spruce beetle (Dendroctonus rufipennis). However, for projecting future bark beetle dynamics there is a critical lack of evidence to differentiate how outbreaks have been promoted by direct effects of …

Spruce beetle outbreak was not driven by drought stress: evidence from a tree-ring iso-demographic approach indicate temperatures were more important

Jessika M. Pettit, Steven L. Voelker, R. Justin DeRose, Julia I. Burton

Climate change has amplified eruptive bark beetle outbreaks over recent decades. However, for projecting future bark beetle dynamics there is a critical lack of evidence to differentiate how outbreaks have been promoted by direct effects of warmer temperatures on beetle life cycles …

Epidemic spruce beetle outbreak changes drivers of Engelmann spruce regeneration

Jessika M. Pettit, Julia I. Burton, R. Justin DeRose, James N. Long et autres

Abstract Climate‐mediated disturbances outside the range of historical variability can have severe consequences on vital, post‐disturbance regeneration processes. High‐elevation forests of the Rocky Mountains that are dominated by Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa) are expected to be sensitive …
