Climatic changes are predicted to significantly affect the frequency and severity of disturbances that shape forest ecosystems. We provide a synthesis of climate change effects on native bark beetles, important mortality agents of conifers in western North America. Because of differences in temperature-dependent life-history strategies, including cold-induced mortality and developmental timing, responses to warming will differ among and within bark beetle species. The success of bark beetle…

Warming increased bark beetle‐induced tree mortality by 30% during an extreme drought in California
- Environmental ScienceGlobal change biology
- 2021
Assessment of how contemporary warming affected western pine beetle populations and mortality of its host, ponderosa pine, during an extreme drought in the Sierra Nevada, California, and United States found that contemporary warming increased the development rate of the western pine beetles and decreased the overwinter mortality rate ofWestern pine beetle larvae leading to increased population growth during periods of lowered tree defense.
Climate and bark beetle effects on forest productivity -- linking dendroecology with forest landscape modeling

Modeling the Impacts of Two Bark Beetle Species Under a Warming Climate in the Southwestern USA: Ecological and Economic Consequences
- Environmental ScienceEnvironmental management

Forest thinning treatments that reduce forest susceptibility to beetle outbreak result in higher net present values than no action scenarios, and combined with other deleterious consequences associated with beetle outbreaks, the results suggest that forest thinning treatment play a useful role in a period of climate warming.

Model Analysis of Mountain Pine Beetle (Coleoptera: Scolytidae) Seasonality
- Environmental Science
- 1999
The results indicate that an adaptive seasonality is a natural consequence of the interaction between developmental parameters and seasonal temperatures, and although this adaptive phenology appears to be resilient to temperature fluctuations, changes in climate within the magnitude of predicted climate change under a CO2 doubling scenario are capable of shifting a thermologically hostile environment to a thermally benign environment.

A conceptual framework using one system as a model is presented, emphasizing interactions across levels of biological hierarchy and spatiotemporal scales, and systems in which endogenous feedbacks can dominate after external forces foster the initial breach of thresholds appear particularly sensitive to anthropogenic perturbations.
