Abstract 1  One expected effect of global climate change on insect populations is a shift in geographical distributions toward higher latitudes and higher elevations. Southern pine beetle Dendroctonus frontalis and mountain pine beetle Dendroctonus ponderosae undergo regional outbreaks that result in large‐scale disturbances to pine forests in the south‐eastern and western United States, respectively. 2  Our objective was to investigate potential range shifts under climate change of outbreak… 

Threats to North American forests from southern pine beetle with warming winters.

In coming decades, warmer winters are likely to ease range constraints on many cold-limited forest insects1-5. Recent unprecedented expansion of the southern pine beetle (SPB, Dendroctonus frontalis)

Climate change could alter the distribution of mountain pine beetle outbreaks in western Canada

Climate change can markedly impact biology, population ecology, and spatial patterns of eruptive insects due to the direct influence of temperature on insect development and population success. The

Climate and weather influences on spatial temporal patterns of mountain pine beetle populations in Washington and Oregon.

The observed number of trees killed by mountain pine beetles per square kilometer in Oregon and Washington, USA, over the past three decades is used to quantify and assess the influence of climate and weather variables on beetle activity over longer time periods and larger scales than previously studied.

Mountain pine beetle and forest carbon feedback to climate change

The cumulative impact of the mountain pine beetle outbreak in the affected region during 2000–2020 will be 270 megatonnes (Mt) carbon, which converted the forest from a small net carbon sink to a large net carbon source both during and immediately after the outbreak.

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

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.

Carbon Storage Responses of Subalpine Forests to Mountain Pine Beetle Outbreaks Under Current and Altered Climate Regimes in Western North America.

This research will, for the first time, provide data documenting post-outbreak carbon dynamics under current and altered climate scenarios, which will provide the basis for developing a carbon-based, ecological rationale for future outbreak management in western forests.

Changing temperatures influence suitability for modeled mountain pine beetle (Dendroctonus ponderosae) outbreaks in the western United States

[1] Insect outbreaks are significant disturbances in forests of the western United States, with infestation comparable in area to fire. Outbreaks of mountain pine beetle (Dendroctonus ponderosae

Risk and damage of southern pine beetle outbreaks under global climate change

1-1-2004 Risk and Damage of Southern Pine Beetle Outbreaks Under Global Climate Change

This study, using the panel data modeling approach, investigates the relationships between climatic variables and southern pine beetle (SPB) (Dendroctonus frontalis Zimmermann) infestations and

Climate change effects on native fauna of northeastern forests 1

We review the observed and potential effects of climate change on native fauna of forests in northeastern North America by focusing on mammals, birds, amphibians, and insects. Our assessment is



Effects of Climatic Stress Upon Outbreaks of the Southern Pine Beetle

The regression model predicted the severe outbreak of the southern pine beetle which occurred July 1973, and isolated the climatic trigger mechanisms responsible for the outbreak.

Latitudinal shifts in spruce budworm (Lepidoptera: Tortricidae) outbreaks and spruce-fir forest distrbutions with climate change

This work investigated potential range shifts for the spruce budworm in the northeastern and north central United States using maps of historical outbreak areas, climatic variables, and the distribution of spruce-fir forests in a geographic information system, and developed canonical discriminant function models of the occurrence of defoliation and the distributed forests as functions of Climatic variables.

Assessment of climatic warming using a model of forest species migration

Model Analysis of Mountain Pine Beetle (Coleoptera: Scolytidae) Seasonality

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.

Climate and the northern distribution limits of Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae)

The physiologically based models provide a tool for guiding land management decisions in forests and illustrate a general approach for predicting the regional effects of climatic patterns on the distribution of organisms.

The Mountain Pine Beetle in Western North America

The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Scolytidae), is generally considered the most destructive of all Western forest insects.46 Periodic outbreaks may devastate

Southern Pine Beetle

The southern pine beetle (Dendroctonus frontalis Zimmermann) is one of pine's most destructive insect enemies in the Southern United States, Mexico, and Central America. Because populations build

The Southern Pine Beetle

The Southern pine beetle is the most destructive insect pest of pine forests in the southeastern United States and in parts of Mexico and Central America and epitomizes the definition of its genus, killer of trees.
