Abstract The arthropods and microbes found in trees attacked by the southern pine beetle (Dendroctonus frontalis Zimmermann) have long been referred to as “southern pine beetle associates.” This community includes predators, parasitoids, competitors, mutualists,...
Abstract Many of the mountain summits of Acadia National Park (ACAD) are dominated by Pinus rigida (Pitch Pine). The ACAD Pitch Pine population is particularly valuable due to its position at the northernmost edge of the species' range, its association with unique...
Abstract Insects and diseases are important disturbance agents in Canadian forests and there is concern that their impacts will intensify under climate change. Here we report on an effort to model and map the climate niches of more than 4000 forest insect and fungus...
Abstract endo-Brevicomin, a pheromone component for tree-killing bark beetle Dendroctonus frontalis Zimmermann, the southern pine beetle, has a “peaked,” biphasic dose-response, being synergistic with attractants (pheromone component frontalin and host odors) at low...
Abstract Abiotic and biotic forest disturbances can have many impacts to forest ecosystem services, including to forest water use. Studies on impacts to forest evapotranspiration have been conducted on the mountain pine beetle (Dendroctonus ponderosae) in western...
Abstract The southern pine beetle (SPB) is a serious pest of pine forests from Central America to the eastern United States, with a recent range expansion into the northeastern United States. Efforts to detect and monitor SPB activity began in 1960 as part of an...
Abstract Intraspecific genetic variation underpins many evolutionary processes and phenomena. For species considered pests, the dynamics of how genetic variation is distributed geographically take on a greater importance, because they can impact pest-management...
Abstract Bark beetle infestations have historically been primary drivers of stand thinning in Mexican pine forests. However, bark beetle impacts have become increasingly extensive and intense, apparently associated with climate change. Our objective was to describe...
Abstract Timely detection of insect infestation (or other disturbance) in a forest is vital for an adequate response plan to be developed. To determine the status of an active infestation of southern pine beetle (Dendroctonus frontalis) in the Bienville National...
