Paper Session III-B - Overview of the Orbiting Radio Communications Asset (ORCA) Mission

The Orbiting Radio Communications Asset (ORCA) mission is a commercial mission being designed, built and conducted by the Iowa Space Grant Consortium, supported by Rockwell Collins, and Space Industries. The mission will utilize advanced technology digital radio equipment provided by Rockwell to survey the low-earth orbit radio spectrum. This survey is of interest to both the commercial communications industry and to the scientific radio astronomy community. In addition to the survey, the spacecraft will provide an on-orbit transmit and receive test platform for advanced communications technologies that can be fully reprogrammed from the control station. A significant feature of the ORCA mission is the intimate involvement of students from Drake University, the University of Iowa, the University of Northern Iowa, and Iowa State University. These students will be involved in all aspects of the mission design, development, and staff the operations center after the initial mission

South Carolina Department of Transportation and the United States Department of Agriculture, Partnering for Success in Migratory Bird Treaty Act Compliance: A Case Study

The South Carolina Department of Transportation (SCDOT) is responsible for maintaining over 8,400 bridges statewide and several species of migratory birds use these structures as nesting locations. These birds, including their nests and eggs, are protected under the Migratory Bird Treaty Act (MBTA). During a review of MBTA compliance in 2014, SCDOT concluded that they had no procedures in place to allow take to occur when active migratory bird nests were found within project limits. Project delays were the only management method available when active nests were found. SCDOT entered a Cooperative Service Agreement with USDA Wildlife Services (WS) in 2016 to address MBTA compliance on SCDOT projects. The agreement called for WS to manage migratory birds at bridge projects to prevent project delays. WS would repeatedly visit bridge projects, survey the bridges for nests, and remove the nests before they became active. Since 2016, WS has inspected 233 bridges and migratory birds were present at approximately 66% of those bridges with a total of 9,250 inactive nests being removed using a variety of methods. Since the partnership’s inception, construction delays due to migratory birds have been completely avoided with an average cost per project of $1,525. With the passage of a new motor fuel user fee in South Carolina, SCDOT plans to replace 465 bridges over the next 10 years. This increase in work will require continued development and implementation of the partnership to effectively meet the rapidly growing transportation needs while minimizing impacts to species protected under the MBTA

The Change in Prevalence of Campylobacter on Chicken Carcasses During Processing: A Systematic Review

A systematic review was conducted to evaluate the change in prevalence of Campylobacter on chicken carcasses during processing. A structured literature search of 8 electronic databases using the key words for Campylobacter, chicken, and processing identified 1,734 unique citations. Abstracts were screened for relevance by 2 independent reviewers. Thirty-two studies described prevalence at more than one stage during processing and were included in this review. Of the studies that described the prevalence of Campylobacter on carcasses before and after specific stages of processing, the chilling stage had the greatest number of studies (9), followed by washing (6), defeathering (4), scalding (2), and evisceration (1). Studies that sampled before and after scalding or chilling, or both, showed that the prevalence of Campylobacter generally decreased immediately after the stage (scalding: 20.0 to 40.0% decrease; chilling: 100.0% decrease to 26.6% increase). The prevalence of Campylobacter increased after defeathering (10.0 to 72.0%) and evisceration (15.0%). The prevalence after washing was inconsistent among studies (23.0% decrease to 13.3% increase). Eleven studies reported the concentration of Campylobacter, as well as, or instead of, the prevalence. Studies that sampled before and after specific stages of processing showed that the concentration of Campylobacter decreased after scalding (minimum decrease of 1.3 cfu/g, maximum decrease of 2.9 cfu/mL), evisceration (0.3 cfu/g), washing (minimum 0.3 cfu/mL, maximum 1.1 cfu/mL), and chilling (minimum 0.2 cfu/g, maximum 1.7 cfu/carcass) and increased after defeathering (minimum 0.4 cfu/g, maximum 2.9 cfu/mL). Available evidence is sparse and suggests more data are needed to understand the magnitude and mechanism by which the prevalence and concentration of Campylobacter changes during processing. This understanding should help researchers and program developers identify the most likely points in processing to implement effective control efforts. For example, if contamination will occur during defeathering and likely during evisceration, critical control points postevisceration are likely to have a greater effect on the end product going to the consumer

Evaluation of Bird Shield as a blackbird repellent in ripening rice and sunflower fields

Chemical repellents sometimes can provide a nonlethal alternative for reducing wildlife impacts to agricultural production. In late summer and autumn 2002, we evaluated Bird Shield™ (active ingredient: methyl anthranilate, Bird Shield Repellent Corporation, Spokane, Wash.) as a blackbird (Icteridae) repellent in Missouri rice fields and North Dakota sunflower fields. We selected 5 pairs of ripening rice fields in southeastern Missouri and randomly allocated treatments (treated and control) within pairs. The repellent was aerially applied by fixed-winged aircraft at the recommended label rate and volume (1.17 L Bird Shield/ha and 46.7 L/ha, respectively); 1 field received 2X the label rate. We observed no difference in average bird activity (birds/minute) between treated and control fields over the 3-day posttreatment period (P = 0.503). We used reversed-phase liquid chromatography to quantify methyl anthranilate residues in treated fields. The maximum concentration of methyl anthranilate in rice samples was 4.71 μg/g. This concentration was below reported threshold values that irritate birds. In North Dakota we selected 6 pairs of sunflower fields used by foraging blackbirds. We randomly selected 1 field from each pair for 2 aerial applications of Bird Shield at the label-recommended rate ~1 week apart. The remaining 6 fields served as controls. Daily bird counts, starting the first day of application and continuing for 5–7 days after the second application, showed similar numbers of blackbirds within treated and control fields (P = 0.964). We observed no difference in sunflower damage within treated and control fields (P = 0.172) prior and subsequent to the treatment. Bird Shield was not effective for repelling blackbirds from ripening rice and sunflower fields

Feral swine harming insular sea turtle reproduction: The origin, impacts, behavior and elimination of an invasive species

Feral swine are among the world\u27s most destructive invasive species wherever they are found, with translocations figuring prominently in their range expansions. In contrast, sea turtles are beloved species that are listed as threatened or endangered throughout the world and are the focus of intense conservation efforts. Nest predation by feral swine severely harms sea turtle reproduction in many locations around the world. Here we quantify and economically assess feral swine nest predation at North Island, South Carolina, an important loggerhead sea turtle nesting beach. Feral swine depredation of North Island sea turtle nests was first detected in 2005, with annual nest monitoring initiated in 2010 documenting nearly total losses to feral swine in 2010 and 2011. The cumulative valuation of annual losses for North Island from 2010 to 2016 ranged as high as $1,166,500. To improve nesting success, an integrated approach for eliminating feral swine was implemented in 2010 and greatly intensified in 2013 by adding federal experts. Removal efforts were challenging due to the island\u27s remoteness and impenetrable habitats, weather, hazards in accessing the island, and wariness of the animals, especially as their population diminished. Removal of the final 11 swine required efforts from 2014 to 2016. Nest predation was highly variable and provided another example of the significance of conditioning by feral swine to sea turtle nests on the consequent severity of nest predation. Even the final individual inflicted heavy losses before his removal. Genetic analyses of feral swine removed from North Island and the adjacent mainland revealed that the island\u27s population did not originate from the nearby mainland, meaning they were (illegally) introduced to the island
