- Technical assistance with the implementation of the Interagency Monitoring Action Plan (I-MAP) for Quagga Mussels is ongoing. During this quarter, analysis was completed for 21 adult/juvenile samples and analyses of the remaining samples are underway. A manuscript describing the I-MAP and its history, current recommended monitoring, and recommended future monitoring and a separate manuscript describing the I-MAP’s monitoring protocol were accepted for publication in the journal Aquatic Invasions. Two other manuscripts describing other aspects of the I-MAP program were published in Lake and Reservoir Management.

Abundance And Size Of Quagga Mussels (Dreissena Bugensis) Veligers In Lake Mead, Nevada-Arizona, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong
Abundance And Size Of Quagga Mussels (Dreissena Bugensis) Veligers In Lake Mead, Nevada-Arizona, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong
Environmental & Occupational Health Faculty Publications
The planktonic veligers of the invasive quagga mussel were present year-round from April 2008 to March 2009 in Lake Mead, with high abundance from September to October (>20 veligers/L), whereas the percentage of competent veligers, in terms of the ability to settle, peaked from November 2008 to January 2009 (>60%). The results from this experiment are useful in understanding the life history and population dynamics of quagga mussels in the lower Colorado River Basin.

Dreissenid mussels including zebra mussel (Dreissena polymorpha Pallas, 1771), originating from the Ponto-Caspian area, and quagga mussel (Dreissena rostriformis bugensis Andrusov, 1897), originating from the mouths of the Rivers Southern Bug and Dnieper are both species native to Eastern Europe, which were accidently introduced into the Laurentian Great Lakes in North America in the 1980s in ballast water (Carlton 2008; Van der Velde et al 2010). Dreissenid mussels have created severe ecological, recreational and economic impacts on many systems because they are biofoulers and efficient ecological engineers that filter large quantities of water. Examples of these wide-ranging impacts are discussed …

Environmental & Occupational Health Faculty Publications
The 100th Meridian Initiative was developed to help prevent the spread of aquatic nuisance species (ANS) through boater education and research on boater movement patterns and behaviors. Surveys employing these elements were conducted at Lake Mead National Recreation Area (LMNRA) in 2002-2003 before the discovery of the quagga mussel (Dreissena rostiformis bugensis Andrusov 1897) and in 2007-2008 after an established population of quagga mussels was found in the Lake. Boaters were asked questions in a personal interview or a mail-in survey regarding what body of water they had previously launched their watercraft in, where they were planning to launch next, …

Following the discovery of quagga mussels in Lake Mead, Nevada-Arizona, USA, a variety of federal, state and regional agencies set up monitoring programs to evaluate and gain information to help minimize the impacts, or potential impacts, of quagga mussels to their facilities and lake ecology. While the agencies have worked closely and shared monitoring data and findings from the beginning of the infestation, there has been no documented comprehensive monitoring program to describe and record the various quagga mussel-related monitoring needs. Ad hoc interagency quagga mussel meeting representatives established an Interagency Monitoring Action Plan (I-MAP), which outlines agency objectives related …
Environmental Factors Affecting Settlement Of Quagga Mussel (Dreissena Rostriformis Bugensis) Veligers In Lake Mead, Nevada-Arizona, Usa, Dong Chen, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong
Environmental Factors Affecting Settlement Of Quagga Mussel (Dreissena Rostriformis Bugensis) Veligers In Lake Mead, Nevada-Arizona, Usa, Dong Chen, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong
Environmental & Occupational Health Faculty Publications
Environmental factors that can affect the settlement rate of quagga mussel veligers include flow velocity, water temperature, pH, dissolved oxygen (DO), conductivity, total organic carbon (TOC), and the surface roughness of monitoring substrates. In the present study, six artificial substrates, Acrylonitrile Butadiene Styrene (ABS) plastic, High Density Polyethylene (HDPE) plastic, Concrete Underlayment Board (CUB), aluminum, stainless steel and fiberglass, were used to monitor the settlement of quagga mussel veligers at different water depths in Lake Mead, Nevada-Arizona, USA. Considering the hierarchical data structure of observed mussel densities, we investigated the relationship between mussel settlement on monitoring substrates and the surrounding …

The discovery of quagga mussels (Dreissena rostriformis bugensis) in Lake Mead, Nevada-Arizona, on January 6, 2007 is the first known occurrence of dreissenid species in the western United States. This study developed elements of a cost-effective and standardized quagga mussel-monitoring program for Lake Mead using preliminary data to arrive at statistically based numbers of sampling sites. To represent the abundance of adult/juvenile quagga mussels in Lake Mead’s heterogeneous floor with 95% confidence, a stratified simple random sampling design revealed a requirement of 41 samples from hard substrates (i.e., rocky areas) and 97 samples from soft substrates (i.e., sandy and muddy …
