History of Quagga Mussels
History of Quagga Mussels By Christine Moskell WS ‘08 Zebra mussels (Dreissena polymorpha) have long been the poster child of invasive species in Seneca Lake. Most people don’t even realize there are other varieties of mussels inhabiting the lake. Today, the tide is changing for zebra mussels in Seneca Lake, as another invasive mussel species has displaced the zebra mussels. Meet the quagga mussel. A close relative to zebra mussels, Quagga mussels (Dreissena bugensis) invaded the Finger Lakes in the same way as zebra mussels. Native to Ukraine, quagga mussels were first transported to the United States when foreign ships unknowingly carrying microscopic quagga larvae discharged their ballast water into the Great Lakes. Quagga mussels were first observed in the United States in the Great Lakes in September 1989, but were not at first considered a different species from zebra mussels.1 In 1991 during a zebra mussel survey near Palmyra, New York, researchers Dr. Bernie May of Cornell University and Dr. Ellen Marsden of the Illinois Natural Survey discovered a mussel with a different genotype than the zebra mussels.2 Genetic tests confirmed that this unique mussel was indeed a different species of Dreissena. The mussel was named “quagga” after an extinct African relative of the zebra. 3 Like zebra mussels, quagga mussels spread to the Finger Lakes via the waterways connected to the Great Lakes. The quagga mussel first arrived in Seneca Lake in 2000.4 Since their arrival to the United States, quagga mussels have expanded their populations throughout the country. Quagga mussels have been established in four of the five Great Lakes; Lake Michigan, Lake Huron, Lake Erie and Lake Ontario. -

Peck Department of Biology Brigham Young University Copyright © 2017 Joshua A. Verde All Rights Reserved ABSTRACT Lake Powell Food Web Structure: Predicting Effects of Quagga Mussel Joshua A. Verde Department of Biology, BYU Master of Science Food webs in aquatic ecosystems can be dramatically altered by invasive species. Quagga mussels are prevalent invaders that compete with existing species and disrupt nutrient cycling. In 2012, the Quagga Mussel (Dreissena rostriformus bugensis) was introduced into Lake Powell and is expected to move throughout the reservoir in the near future. Stable isotope analysis is a powerful tool for characterizing food webs and trophic interactions. -

Arizona Historic Bridge Inventory | Pages 164-191

The original study employed 1945 as a cut-off date. This study inventories and evaluates all of the pre-1964 vehicular bridges and grade separations currently maintained in ADOT’s Structure Inventory and Appraisal [SI&A] listing. It includes all structures of all struc- tural types in current use on the state, county and city road systems. Additionally it includes bridges on selected federal lands (e.g., National Forests, Davis-Monthan Air Force Base) that have been included in the SI&A list. Generally not included are railroad bridges other than highway underpasses; structures maintained by federal agencies (e.g., National Park Service) other than those included in the SI&A; structures in private ownership; and structures that have been dismantled or permanently closed to vehicular traffic. There are exceptions to this, however, and several abandoned and/or privately owned structures of particular impor- tance have been included at the discretion of the consultant. The bridges included in this Inventory have not been evaluated as parts of larger road structures or historic highway districts, although they are clearly integral parts of larger highway resources. -
Linen, Section 2, G to Indians
Arizona, Linen Radio Cards Post Card Collection Section 2—G to Indians-Apache By Al Ring LINEN ERA (1930-1945 (1960?) New American printing processes allowed printing on postcards with a high rag content. This was a marked improvement over the “White Border” postcard. The rag content also gave these postcards a textured “feel”. They were also cheaper to produce and allowed the use of bright dyes for image coloring. They proved to be extremely popular with roadside establishments seeking cheap advertising. Linen postcards document every step along the way of the building of America’s highway infra-structure. Most notable among the early linen publishers was the firm of Curt Teich. The majority of linen postcard production ended around 1939 with the advent of the color “chrome” postcard. However, a few linen firms (mainly southern) published until well into the late 50s. Real photo publishers of black & white images continued to have success. Faster reproducing equipment and lowering costs led to an explosion of real photo mass produced postcards. Once again a war interfered with the postcard industry (WWII). During the war, shortages and a need for military personnel forced many postcard companies to reprint older views WHEN printing material was available. Photos at 43%.

Frequently Asked Questions
Frequently Asked Questions Prepared cooperatively by Bureau of Reclamation, National Park Service, U.S. Fish and Wildlife Service, and U.S. Geological Survey What is a high-flow experiment? A high-flow experiment is a release of water from Glen Canyon Dam intended to rebuild high- elevation sandbars, deposit nutrients, and restore backwater channels. For 2008, it is proposed that approximately 41,000 cubic feet per second (cfs) of water be released from Glen Canyon Dam for 60 hours. What are the anticipated benefits of a high-flow experiment? Higher than normal flows are required to deposit sand up and onto eroded Grand Canyon sandbars, which serve as camping beaches for river runners and hikers, provide sediment needed to protect archaeological resources from erosion and weathering, and create habitats used by native fishes, particularly the endangered humpback chub (Gila cypha) and other wildlife. The experimental studies associated with the proposed 2008 high-flow experiment are designed to build upon existing scientific knowledge to inform managers about the efficacy of using high flows from the dam to improve a range of resources, including not only sandbars and humpback chub habitat, but also rainbow trout (Oncorhynchus mykiss), the aquatic food base, riparian vegetation, archaeological sites, and water quality. What is adaptive management? Adaptive management is generally understood to be a systematic process for continually improving management practices over time by emphasizing learning through experimentation. Adaptive management also incorporates collaboration among stakeholders, managers, and scientists who are knowledgeable about the system being evaluated. The comprehensive, iterative, and collaborative nature of an adaptive management approach is why it was implemented as part of the long-term management strategy for refining operations of Glen Canyon Dam to improve downstream resources. -

This study examined the trophic dynamic plasticity of round goby along a depth gradient based on laboratory and field observations to determine prey species consumed and mussel prey size selection. Prey size selection in the laboratory was assessed by presenting individual round goby with quagga mussels ( Dreissena rostriformis bugensis) of various class sizes (i.e., 6.0– 9.9 mm, 10.0– 12.9 mm, 13.0– 15.9 mm, and 16.0– 18.9 mm in length).
