Spatial Synchrony in Population Dynamics
In addition to intraspecific synchrony, there are many examples of synchrony among populations of different species, the causes of which are similarly complex and difficult to identify. Expand
Cost of potential emerald ash borer damage in U.S
Emerald ash borer (EAB), a phloem-feeding beetle native to Asia, was discovered near Detroit, MI, and Windsor, ON, in 2002 and has the potential to spread and kill native ash trees throughout the United States. Expand
Economic Impacts of Non-Native Forest Insects in the Continental United States
The damage estimates provide a crucial but previously missing component of cost-benefit analyses to evaluate policies and management options intended to reduce species introductions and could be similarly employed to estimate damages in other countries or natural resource sectors. Expand
Gypsy moth invasion in North America: a quantitative analysis
The gypsy moth, Lymantria dispar (L.), was accidentally introduced to North America in 1868 or 1869. Since that time, the range of this insect has spread to include most of the northeastern states inExpand
Invasion by Exotic Forest Pests: A Threat to Forest Ecosystems
This work presents case histories that illustrate the invasion process via details of the arrival, spread, impact, and management of selected exotic forest pests. Expand
The syn­chronous behavior of gypsy moth populations over fairly large regions sug­gests that weather conditions drive the system in some manner, but the mechanisms remain obscure. Expand
Population ecology of insect invasions and their management.
During the establishment phase of a biological invasion, population dynamics are strongly influenced by Allee effects and stochastic dynamics, both of which may lead to extinction of low-densityExpand
Historical Accumulation of Nonindigenous Forest Pests in the Continental United States
A comprehensive species list to assess the accumulation rates of nonindigenous forest insects and pathogens established in the United States found sap feeders and foliage feeders dominated the comprehensive list, but phloem- and wood-boring insects and foliageFeeders were often more damaging than expected. Expand
Illustrations and guidelines for selecting statistical methods for quantifying spatial pattern in ecological data
Advice to ecologists with limited experience in spatial analysis is to use simple visualization techniques for initial analysis, and subsequently to select methods that are appropriate for the data type and that answer their specific questions of interest. Expand
Interceptions of Nonindigenous Plant Pests at US Ports of Entry and Border Crossings Over a 17-year Period
Insects dominated the PIN database, with the orders Homoptera, Lepidoptera and Diptera collectively accounting for over 75% of the insect records, while plant pathogens, weeds and mollusks accounted for 13, 7 and 1% of all pest records, respectively. Expand
