**Title**: *Using environmental DNA (eDNA) to elucidate the Asian carp 
invasion front*

**Abstract*:*

Managing rare species, whether they are endangered native species or 
recently introduced invasive species, requires detection of populations 
at low densities. Our recent work demonstrates the usefulness of a novel 
detection tool, molecular surveillance using environmental DNA (eDNA), 
to more accurately describe the invasion fronts of two species of Asian 
carp in Chicago-area canals and waterways. To date we have analyzed over 
1100 water samples from throughout the Chicago area for presence or 
absence of Asian carp eDNA. Positive detections for the invasive species 
have been found throughout the sampled region. Additionally, targeted 
eDNA from Asian carp has been detected on numerous sampling trips north 
of the U.S. Army Corps of Engineers Aquatic Nuisance Species Barrier. 
Quantitative comparisons with traditional fisheries surveillance tools 
illustrate the greater sensitivity of eDNA, and reveal the impending 
risk of invasion to the Laurentian Great Lakes by bighead and silver 
Asian carp. Environmental DNA provides a novel surveillance approach for 
nonindigenous aquatic species. This tool has the ability to detect 
nonnative species such as bighead and silver carp at low densities where 
traditional tools have been shown to fail. Future studies will 
investigate the applicability of eDNA surveillance for other species, 
including threatened and endangered organisms in aquatic environments.
