Invasive insects impact forest carbon dynamics

Forest Health Management and Detection of Invasive Forest Insects

The objectives of this review paper are to provide an overview of issues related to forest health and forest entomology, explain existing methods for forest insect pest detection, and provide background information on a case study of emerald ash borer. Early detection of potentially invasive insect species is a key aspect of preventing these species from causing damage. Invasion management effo...

FOREST ENTOMOLOGY Dispersal of Invasive Forest Insects via Recreational Firewood: A Quantitative Analysis

Recreational travel is a recognized vector for the spread of invasive species in North America. However, there has been little quantitative analysis of the risks posed by such travel and the associated transport of Þrewood. In this study, we analyzed the risk of forest insect spread with Þrewood and estimated related dispersal parameters for application in geographically explicit invasion model...

Tree Diversity Limits the Impact of an Invasive Forest Pest

The impact of invasive herbivore species may be lower in more diverse plant communities due to mechanisms of associational resistance. According to the "resource concentration hypothesis" the amount and accessibility of host plants is reduced in diverse plant communities, thus limiting the exploitation of resources by consumers. In addition, the "natural enemy hypothesis" suggests that richer p...
