Integrating Mammalian Hazards With Management At U.S. Civil Airports: A Case Study, Kristin M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang
Human–Wildlife Interactions
Wildlife incidents with U.S. civil aircraft cost an estimated $1.4 billion from 1990 to 2010, with mammals 5 times more likely to cause damage than other wildlife. We surveyed 2 general aviation (GA) airports and 6 Part-139 certificated (i.e., certified) airports to assess efficacy of management practices for mammalian species hazardous to aircraft. We obtained information on mammalian species present on airport grounds, types and estimated effectiveness of management techniques, and effort spent on wildlife management. We evaluated management techniques relative to aircraft–wildlife collisions (i.e., incident) frequencies taken from Federal Aviation Administration’s (FAA) National Wildlife Strike Database and species hazard …
Testing Systems Of Avian Perch Deterrents On Electric Power Distribution Poles In Sage-Brush Habitat, James F. Dwyer, Kerrin W. Doloughan
Testing Systems Of Avian Perch Deterrents On Electric Power Distribution Poles In Sage-Brush Habitat, James F. Dwyer, Kerrin W. Doloughan
Human–Wildlife Interactions
In Lincoln County, Washington, USA, greater sage-grouse (Centrocercus urophasianus) and Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) are managed as reintroduced and augmented populations, respectively. Predation by raptors and corvids is a concern, particularly where utility poles may provide hunting perches near leks (i.e., breeding areas). Perch deterrents may offer a mitigating strategy if deterrents reduce the frequency or duration of perching. To investigate the effects of various perch deterrents, we deployed deterrents on 5 power poles retained for use in this study when 33 poles were removed from occupied grouse habitat. We rotated deterrents among poles every 15 to 28 …
Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox
Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox
Human–Wildlife Interactions
Feral cats (Felis catus) are abundant in many parts of the world and pose a threat to native wildlife. Human–wildlife conflicts regarding how feral cats should be managed have increased recently. In Hawaii, previous research has revealed that most residents would like to see the feral cat abundance reduced, but opinions differ regarding which techniques are acceptable for achieving this. This paper describes an analytical hierarchy process that combines rankings of decision criteria by Hawaii’s residents with expert knowledge of the costs and benefits associated with 7 techniques (live-capture and adoption, live-capture and lethal injection, live-capture and lethal gunshot, trap-neuter-release …

Farmers’ Perceptions Of The Impacts Of Human– Wildlife Conflict On Their Livelihood And Natural Resource Management Efforts In Cheha Woreda Of Guraghe Zone, Ethiopia, Dagne Mojo, Jessica Rothschuh, Mehari Alebachew
Human–Wildlife Interactions
There are several livelihood improvement and natural resource management campaigns being undertaken in Ethiopia. In Cheha Woreda District of Guraghe Zone, a research team from the Ethiopian Institute of Agricultural Research, Holetta Research Center, is undertaking a watershed-level intervention to improve sustainable land management practices among resident agrarian families. In 2011, a household survey was conducted to assess farmers’ perceptions of human–wildlife conflicts (HWC) and the effects of these conflicts on land management in Cheha Woreda. One-hundred randomly selected households in the Cheha Woreda were asked to identify any wild or domestic animals that cause damage to their crops. Additionally, …

Population Trends Of Resident And Migratory Canada Geese In Relation To Strikes With Civil Aircraft, Richard A. Dolbeer, John L. Seubert, Michael J. Begier
Human–Wildlife Interactions
Canada geese (Branta canadensis) are of particular concern to aviation in the USA because of their large size, flocking behavior, attraction to airports for grazing, and, for the resident population, year-round presence in urban environments. We documented trends in resident and migrant Canada goose populations in North America from 1970 to 2012, and for 1990 to 2012 examined these trends in relation to trends in reported civil aircraft collisions (strikes) with Canada geese. The overall Canada goose population increased 4.5 fold from 1.26 million in 1970 to 5.69 million in 2012. Most of this overall increase was due …
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
Human–Wildlife Interactions
We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (probability of capture in a single tunnel system using 3 traps; 63%) than nonirrigated alfalfa fields (26%). We did not determine whether this variance was due to behavioral differences between Geomys bursarius and Geomys lutescens. We found …

Wildlife Markets In South China, Alex T. Chow, Szeman Cheung, Peter K. Yip
Human–Wildlife Interactions
China is one of the largest consumers of wild animals for food and traditional Chinese medicine in the world. A large volume of illegal trade has been recorded in the primary cities, such as Hong Kong and Guangzhou, but the wildlife markets in secondary Chinese cities have not been investigated. This study was carried out in 7 cities in Guangdong and Guangxi provinces. Wildlife trade data were collected using semi-structured interview, observation, and market survey. The study documented the selling of 97 animal species, >7,000 individuals. The most frequently used animal groups by quantity were reptiles (51%), followed by birds …
Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short
Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short
Human–Wildlife Interactions
Herbivory by eastern cottontails (Sylvilagus floridanus) can be the source of significant agricultural, nursery, and managed landscape damage. Where cottontails cannot be managed by lethal means or where trap and release is infeasible, repellents may be a reasonable alternative. We tested 8 different repellent formulations (Bobbex Deer Repellent® Canadian formulation concentrate, Bobbex Deer Repellent® Canadian ready-to-use (RTU), Bobbex-R Animal Repellent® concentrate, Bonide Repels All® concentrate, Bonide Deer & Rabbit Repellent® concentrate, Liquid Fence® Deer & Rabbit Repellent concentrate, Plantskydd® soluble powder, and Rabbit Stopper® RTU) on Johnny jump-ups (Viola tricolor), lettuce (Lactuca sativa), and …

Determination Of Residue Levels Of Alpha-Chloralose In Duck Tissues, David A. Goldade, Randal S. Stahl, John. J. Johnston
Human–Wildlife Interactions
Alpha-chloralose (AC) is used to capture nuisance waterfowl so that they can be relocated. Concerns for food safety limit its use prior to or during the waterfowl hunting season. To determine its half-life in tissue, we administered AC to adult male (n = 7) and female (n = 5) mallard ducks (Anas platyrhynchos) via oral gavage. A gel capsule containing 100 μCi of radioactive AC (14C-AC) and sufficient nonlabeled AC to produce a dose of approximately 30 mg/kg was given to each duck.The ducks were euthanized at 2, 6, 10, and 18 hours postdosing …

The Centers for Disease Control (CDC) and USDA Wildlife Services (WS) have been involved in an oral rabies vaccination (ORV) program for raccoons (Procyon lotor) that has slowed the westward spread of raccoon rabies. The objective of this study was to forecast the spread of the disease if an ORV zone was not maintained. A group decision-making process was designed to address the forecasting problem and was implemented using a group of 15 experts and 4 support personnel at a meeting at the USDA National Wildlife Research Center. Ten expansion regions were constructed that described the spread of …

Reducing The Potential For Human–Snake Encounters In A Recreational Park, Evin T. Carter, Omar Attum, Bryan C. Eads, Andrew S. Hoffman, Bruce A. Kingsbury
Human–Wildlife Interactions
Parks and outdoor recreation areas often struggle to balance management for outdoor recreation with the protection of native flora and fauna. Additional complications can arise for land managers when recreation occurs in areas shared with wildlife that are perceived by humans to be dangerous. Despite these issues, many parks may inadvertently increase the potential for human–wildlife encounters through the creation of artificial forest gaps used for recreational purposes. We determined the potential for human encounters with venomous copperhead snakes (Agkistrodon contortrix) at a recreational park in southern Indiana before and after several simulated closures of recreational forest gaps. …
Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson
Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson
Human–Wildlife Interactions
Coyote (Canis latrans) removal is a common, yet controversial, management practice to increase game populations throughout the West. I studied the effect of removal on coyote populations in eastern Nevada from 2004 to 2008 and reviewed 27 available publications to determine the level of human exploitation on my study populations. Removals were performed by USDA Wildlife Services (WS) to benefit game populations and involved the use of trapping, neck snaring, and ground and aerial shooting. To determine if the removal had an effect on the coyote populations, I measured 3 parameters: the presence or absence of skewed sex …

A Spatially Explicit Model Of The White-Tailed Deer Population In Delaware, Brian Jennings, Jacob L. Bowman, Elizabeth L. Tymkiw
Human–Wildlife Interactions
Population models of white-tailed deer (Odocoileus virginianus) are used by many states to predict population levels and aid in making management decisions. Delaware did not have a deer population model, so we developed one and used it to investigate the implications of changes to the harvest. We modeled 7 changes to the harvest regime and compared these changes to the base line of no changes to the harvest regime. We used survival rates, reproductive rates, harvest data, a population estimate, and spotlight counts to construct the model. The model scenario began in February 2006 and ran until August …

Effectiveness Of A Simulated Pack To Manipulate Wolf Movements, Christine M. Anhalt, Timothy R. Van Deelen, Ronald N. Schultz, Adrian P. Wydeven
Human–Wildlife Interactions
Bioboundaries, also called biofences, are deterrents that attempt to exploit certain innate behaviors to exclude wildlife from target areas. We hypothesized that human-deployed scent marks and playbacks of foreign howls could simulate a territorial gray wolf (Canis lupus) pack impinging on a resident pack, thereby causing the resident pack to move. During summer 2010, we deployed a simulated-pack bioboundary near 3 wolf packs in northern Wisconsin and monitored their movements relative to 3 wolf packs experiencing a sham treatment, to control for effects of human presence. We analyzed wolves’ locations (≥1 location per week) and used linear models …

Characteristics And Distribution Of Live-Stock Losses Caused By Wild Carnivores In Maasai Steppe Of Northern Tanzania, Batistino P. Mponzi, Christopher A. Lepczyk, Bernard M. Kissui
Human–Wildlife Interactions
Agricultural development accelerates the loss of habitat for many wildlife species and brings humans and animals in close proximity, resulting in increased human–wildlife conflict. In Africa, such conflicts contribute to carnivore population declines in the form of human retaliation for livestock depredation. However, little knowledge exists about when and where carnivores attack livestock. Given this need, our objectives were to (1) understand the spatial and temporal variation of human–carnivore conflict and (2) identify conflict-prone areas. We addressed these objectives in 18 Tanzanian villages of the Maasai Steppe using livestock depredation data on lions (Panthera leo), spotted hyenas ( …

American Black Bear–Apiary Conflicts In Michigan, Beverly K. Mckinley, Jerrold L. Belant, Dwayne R. Etter
Human–Wildlife Interactions
American black bear (Ursus americanus) damage to apiaries can result in substantial economic loss. We used records of black–bear apiary conflicts collected by the Michigan Department of Natural Resources to characterize damage in the Upper and Northern Lower peninsulas of Michigan from April 2003 to May 2011. Most conflicts occurred between May and July, and the number of conflicts decreased across years. The number of reported conflicts was directly correlated with bear population size. However, we found no positive association between numbers of reported conflicts with bear condition as indexed by winter severity and hive abundance. Intolerance toward …

Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu
Human–Wildlife Interactions
Animal–vehicle collisions (AVCs) cause animal death, human injury, and vehicle damage. Uncovering the general patterns and related ecological processes of AVCs is useful for developing mitigation strategies. We examined some previous patterns about AVCs from records in Alabama during 2001 to 2011. The results confirm that: (1) there was a seasonal pattern, with >50% of AVCs occurring in winter; (2) AVCs occurred most frequently at dawn and dusk in the diurnal pattern; and (3) most AVCs occurred on county highways. However, interstate and federal highways had higher numbers of AVCs per km of road. Counties within metropolitan areas had more …
Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn
Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn
Human–Wildlife Interactions
Aviation safety is an important concern in wildlife management as bird strikes risk human lives and result in costly damage. Habitat management can decrease bird abundances locally at airports. We tested soil manipulation as a technique to reduce local bird presence by establishing experimental plots with either intact topsoil or “stripped” subsoil with the aim of decreasing foraging substrate for birds. We estimated invertebrate abundance, and observed bird presence from 2006 to 2008. More birds visited topsoil plots (151.5 birds/ ha/hour) than subsoil plots (72.7 birds/ha/hour). Topsoil plots supported a greater biomass of invertebrates than subsoil plots ( = 0.39 …

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball
Human–Wildlife Interactions
We examined the repellency of a commercially available animal repellent to determine the efficacy of its application to objects that are attractive to coyotes (Canis latrans). Specifically, we aimed to both prevent chewing behavior by coyotes on a nylon-like strapping material, which is used to construct barrier-arresting systems on military airstrips, and determine the ability of the solution to prevent the animals from repeating the undesired behavior. We mixed Ropel® Animal and Rodent Repellent with a liquid latex sticker to form a 2% latex and 98% Ropel solution. We used a 2% latex and 98% water solution as …

Mathematics, Engineering, Science Achievement (MESA) outreach programs are partnerships between K-12 schools and higher education in nine states. MESA efforts introduce integrated experiences in science, mathematics and engineering to K-12 students from groups that are traditionally underrepresented in the STEM disciplines. This exploratory study examined the influence of selected MESA activities on students' self-efficacy, their perceptions of engineering, and their interest in engineering and other STEM fields. Field trips, guest lecturers, design competitions, hands-on activities and student career and academic advisement were of specific interest in this survey. The project also investigated the relationship between student engagement in MESA and …

Friction Coefficients For Dried Distillers Grains On Eight Structural Surfaces, G. C. Nyendu, S. Pflum, P. Schumacher, C. J. Bern, T. J. Brumm
Biological Engineering Faculty Publications
Static and dynamic coefficients of friction on structural surfaces play important roles in the power requirements and material selection for equipment used in handling and storing agricultural commodities. However, friction data on dried distillers grains with solubles (DDGS) is limited. Further, lack of a standardized method for determining friction coefficient on grain handling materials presents a challenge. This article describes studies carried out to determine the static coefficient of friction (•_s) and dynamic coefficient of friction (•_d) for corn DDGS at 10%, 8.2%, and 6.5% moisture content (all moistures are % wet basis) on eight structural surfaces: High-Density Polyethylene (HDPE), …

Salmonella encounters various stresses in the environment and in the host during infection. The effects of cold (5 C, 48 h), peroxide (5 mM H2O2, 5 h) and acid stress (pH 4.0, 90 min) were tested on pathogenicity of Salmonella. Prior exposure of Salmonella to cold stress significantly (P < 0.05) increased adhesion and invasion of cultured intestinal epithelial (Caco-2) cells. This increased Salmonella-host cell association was also correlated with significant induction of several virulence-associated genes, implying an increased potential of cold-stressed Salmonella to cause an infection. In Caco-2 cells infected with cold-stressed Salmonella, genes involved in the electron transfer chain were significantly induced, but no simultaneous significant increase in expression of antioxidant genes that neutralize the effect of superoxide radicals or reactive oxygen species was observed. Increased production of caspase 9 and caspase 3/7 was confirmed during host cell infection with cold-stressed Salmonella. Further, a prophage gene, STM2699, induced in cold-stressed Salmonella and a spectrin gene, SPTAN1, induced in Salmonella-infected intestinal epithelial cells were found to have a significant contribution in increased adhesion and invasion of cold-stressed Salmonella in epithelial cells.

Mycoplasmas & Mycobacteria: Minimalists At Work, Shalee Killpack
Undergraduate Honors Capstone Projects
Mycoplasmas and mycobacteria are two types of opportunistic pathogens whose prevalence and virulence have long been underestimated. As a broad overview, this paper will explore the current understanding of these bacteria as well as some common pathological outcomes they can induce. Chronic infections, such as contagious bovine pleuropneumonia and Johne's disease, can have extensive health and economic impacts on animal industries when improperly managed. Contamination of biopharmaceuticals and human variants of disease, are also matters of concern as more research is conducted in these areas. A more detailed understanding of these bacteria is beginning to emerge-a view which reveals mycoplasmas …

Reports
Tests of horizontally restrained rocket motors at the ATK facility in Promontory, Utah,USA result in the deposition of an estimated 1.5 million kg of entrained soil and combustion products (mainly aluminum oxide, gaseous hydrogen chloride and water) on the surrounding area. The deposition is referred to as test fire soil (TFS). Farmers observing TFS deposited on their crops expressed concerns regarding the impact of this material. To address these concerns, we exposed corn and alfalfa to TFS collected during a September 2009 test. The impact was evaluated by comparing the growth and tissue composition of controls relative to the treatments. …

Continuing advances in nucleotide sequencing technology are inspiring a suite of genomic approaches in studies of natural populations. Researchers are faced with data management and analytical scales that are increasing by orders of magnitude. With such dramatic advances comes a need to understand biases and error rates, which can be propagated and magnified in large-scale data acquisition and processing. Here we assess genomic sampling biases and the effects of various population-level data filtering strategies in a genotyping-by-sequencing (GBS) protocol. We focus on data from two species of Populus, because this genus has a relatively small genome and is emerging …
