Use of antimycin-microparticles and alfalfa to control Grass Carp Ctenopharyngodon idella

Since their introduction in the 1960’s, grass carp ( Ctenopharyngodon idella) have spread across the North American continent as far north as the U.S./Canadian border in the Great Lakes. Grass carp are an herbivorous species and can significantly reduce the amount of macrophytes and other plant material in a body of water. Subsequently, this can lead to many detrimental effects for certain species...

Hunting Invasive Species with HTCondor: High Throughput Computing for Big Data and Next Generation Sequencing

Large amounts of data are being generated that require hours, days, or even weeks to analyze using traditional computing resources. Innovative solutions must be implemented to analyze the data in a reasonable timeframe. The program HTCondor (https://research.cs.wisc.edu/htcondor/) takes advantage of the processing capacity of individual desktop computers and dedicated computing resources...

Using environmental DNA to extend the window of early detection for dreissenid mussels Using environmental DNA to extend the window of early detection for dreissenid mussels

Tools that bolster early detection of invasive species are needed to prevent their spread. In this study, we assessed if environmental DNA (eDNA) can extend the seasonal window for dreissenid mussel early detection beyond that of plankton tows, which are limited to warmer seasons when mussel larvae are present. We focused eDNA sampling efforts at multiple sites in Tiber Reservoir...

Development of a quantitative PCR method for screening ichthyoplankton samples for bigheaded carps Development of a quantitative PCR method for screening ichthyoplankton samples for bigheaded carps

Monitoring ichthyoplankton is useful for identifying reproductive fronts and spawning locations of bigheaded carps (Hypophthalmichthys spp.). Unfortunately, sorting and identifying ichthyoplankton to monitor for bigheaded carp reproduction is time consuming and expensive. Traditional methods require frequent egg-larvae sampling, sorting of all samples to obtain presumptively identified...

Environmental DNA as a tool to help inform zebra mussel, Dreissena polymorpha, management in inland lakes Environmental DNA as a tool to help inform zebra mussel, Dreissena polymorpha, management in inland lakes

Zebra mussels (Dreissena polymorpha) are an aquatic invasive species that plague much of North America and are difficult to impossible to eradicate once they become established. Therefore, prevention and monitoring are key elements in the control of these organisms. Traditional microscopy is commonly used in monitoring but requires the presence of larval veligers. This limits the times...

Correlating sea lamprey density with environmental DNA detections in the lab Correlating sea lamprey density with environmental DNA detections in the lab

Invasive sea lamprey (Petromyzon marinus Linnaeus, 1758) are currently managed by the Great Lakes Fishery Commission in an effort to reduce pest populations below levels that cause ecological damage. One technique to improve stream population assessments could be molecular surveillance in the form of environmental DNA (eDNA) monitoring. We developed and validated four probe-based...

Field evaluation of carbon dioxide as a fish deterrent at a water management structure along the Illinois River Field evaluation of carbon dioxide as a fish deterrent at a water management structure along the Illinois River

Construction of a water management structure (WMS) in the levee surrounding The Nature Conservancy’s Emiquon Preserve (Havana, Illinois, USA) created a new hydrological connection and potential aquatic invasive species pathway between the Illinois River and a large conservation wetland complex. Site managers need a control tool that deters the upstream passage of non-native fishes into...

The complete mitochondrial genome of Hine’s emerald dragonfly (Somatochlora hineana Williamson) via NGS sequencing The complete mitochondrial genome of Hine’s emerald dragonfly (Somatochlora hineana Williamson) via NGS sequencing

Here, we report the complete mitochondrial genome of the endangered Hine’s emerald dragonfly (HED), Somatochlora hineana Williamson. Data were generated via next generation sequencing (NGS) and assembled using a mitochondrial baiting and iterative mapping approach. The full length circular genome is 15,705 bp with 26.6% GC content. It contains the typical metazoan set of 37 genes: 13...
