Predicted probability of spruce beetle offspring developing in a single year in spruce forests across the range of this insect in North America during three climate normals periods: (a) 1961–1990, (b) 2001–2030, and (c) 2071–2100, and only in the western United States in (d) 1961–1990, (e) 2001–2030, and (f) 2071–2100.

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. ; Parsons, R. A.; Hadlow, A. M.; Cohn, G. M/; McAllister, S. S.; Popp, J. BH

In Alaska alone, the spruce beetle affected approximately 2 million ha during a prolonged outbreak in the 1980s and 1990s (Werner et al.
Large scale beetle population outbreaks have not been observed following wild or prescribed fires, however, most likely because fire-injured trees provide beetles with a single episode, or ‘pulse’ of stressed resources, that are localized and temporary and therefore not sufficient for landscape-scale population growth (36, 37).

2008). U.S. officials say climate change, beetles and a deadly fungus are imperiling the long-term survival of the high-elevation tree found in the western U.S. (Rick Egan/The Salt Lake Tribune via AP, File)

Bark beetle-caused tree mortality can influence subsequent fire behavior, although the spatial and temporal dynamics are complex (34). MF

Specifically, we hypothesized that (a) bark beetle outbreaks under climate change would reduce net ecosystem carbon balance (NECB) and increase uncertainty and (b) these effects could be ameliorated by fuels management.
Bark beetle adults have sophisticated chemoreceptors and behaviors that allow them to recognize host tree species in addition to the potential defensive capacity of the host.
If one does not believe in Global Warming and its effect, seeing Fire, an important forest disturbance that is directly influenced by climate change (Westerling et al. . Zhu

Despite uncertainty in forecasts of future climate parameters that have been downscaled to a forest landscape, predictions of trends in bark beetle population success as a function of the direct effects of temperature will be instrumental in development and application of strategies for management of future forests.
