BACKGROUND The Bean plataspid (Megacopta cribraria) (Hemiptera: Pentatomidae), native to Asia, is becoming an invasive species in North America; its potential spread to soybean producing areas in the US is of great concern. Ecological niche modelling (ENM) has been used increasingly in predicting invasive species' potential distribution; however, poor niche(More)
Molecular definition of disease at the level of the gene and advances in recombinant DNA technology suggest that many diseases are amenable to correction by genes not bearing the defective elements that result in disease. Many questions must be answered before this therapy can be used to correct chronic diseases. These questions fall into safety and(More)
Ecological niche models assume a species niche should be conserved over space and time. Increasingly, studies have determined that niche shifts may occur during biological invasion events. The aim of this study is to examine niche conservation for two invasive crane flies, Tipula oleracea Linnaeus and Tipula paludosa Meigen, after introductions into North(More)
