Validation Of A Nutria (Myocastor Coypus) Environmental Dna Assay Highlights Considerations For Sampling Methodology, Anna M. Mangan, John A. Kronenberger, Ian H. Plummer
Validation Of A Nutria (Myocastor Coypus) Environmental Dna Assay Highlights Considerations For Sampling Methodology, Anna M. Mangan, John A. Kronenberger, Ian H. Plummer
USDA Wildlife Services: Staff Publications
Nutria (Myocastor coypus) is a semiaquatic rodent species that is invasive across multiple regions within the United States. Here, we evaluated a qPCR assay previously described for use in Japan for application across invasive populations in the United States. We also compared two environmental DNA sampling methodologies for this assay: field filtration of large volumes of water passed through filters versus direct sampling of small volumes of water. We validated assay specificity, generality, and sensitivity, compared assay performance between two independent laboratories, and successfully tested the assay in situ on a known wild population. The filtration method required …
Results From Kentucky’S 10-Year Bobwhite Recovery Plan, Cody M. Rhoden, John J. Morgan, Ben A. Robinson, Gary Sprandel
Results From Kentucky’S 10-Year Bobwhite Recovery Plan, Cody M. Rhoden, John J. Morgan, Ben A. Robinson, Gary Sprandel
National Quail Symposium Proceedings
The northern bobwhite (Colinus virginianus; hereafter, bobwhite) has experienced a precipitous population decline through almost all its historical range over the last 6 decades. We initiated a 10-year restoration plan in Kentucky, USA in 2008 and reported on it through 3 published “Road to Recovery” reports along with 30 peer-reviewed articles and abstracts, 2 technical documents, 7 theses or dissertations, and 11 popular literature pieces. Seven Quail Focus Areas were selected across the state based on site personnel, geographic position (east to west), and land ownership (e.g., private, public, state, federal) for monitoring and habitat management. The focus …
Landowner Cooperative Key To Success In The Bee Ridge Quail Focus Area, John A. Pinkowski, Beth A. Emmerich, William T. White
Landowner Cooperative Key To Success In The Bee Ridge Quail Focus Area, John A. Pinkowski, Beth A. Emmerich, William T. White
National Quail Symposium Proceedings
The Missouri Department of Conservation (MDC) began establishing Quail Focus Areas (QFAs) on private lands in 2004. The goal of QFAs is to increase and expand quail habitat management efforts around a core area. Because most (93%) of the landscape of Missouri, USA is in private ownership, habitat improvement programs on private lands have greater potential to impact quail populations than on public lands alone. A motivated group of landowners led the charge to begin habitat improvement efforts in the Bee Ridge QFA. This group was instrumental in starting earlier monitoring efforts to determine whether habitat improvements were leading to …
Habitat Works: How Partnerships And Habitat Improvement Have Restored Quail Populations In The 2c Quail Focus Area, E. Lee Metcalf, Beth A. Emmerich, William T. White
Habitat Works: How Partnerships And Habitat Improvement Have Restored Quail Populations In The 2c Quail Focus Area, E. Lee Metcalf, Beth A. Emmerich, William T. White
National Quail Symposium Proceedings
The Missouri Department of Conservation (MDC) began establishing Quail Focus Areas (QFAs) on private lands in 2004. The goal of QFAs was to bring groups of landowners together to manage bobwhite habitat on a larger scale in a targeted landscape. Through a variety of state, federal, and other partnership programs, habitat improvement efforts have resulted in large increases in northern bobwhite (Colinus virginianus; hereafter, bobwhite) numbers in the 2C QFA. In spring 2013, MDC staff and Quail Forever biologists began monitoring bobwhite and songbirds in a portion of the 2C QFA in Carroll County, Missouri, USA and in …
Monitoring For Wolves, Jeff Hansen, Cat Urbigkit
Monitoring For Wolves, Jeff Hansen, Cat Urbigkit
Wildlife Damage Management Technical Series
Gray wolves (Canis lupus) and Mexican wolves (Canis lupus baileyi) once again roam across landscapes where they have been absent for decades (Figure 1). With wolf range expansion comes increased opportunities for conflicts when wolves harass or prey on domestic livestock or other animals. Wolves have relatively high reproductive and dispersal rates but detecting individual animals in low-density populations is difficult without a concerted monitoring effort. In fact, wolf presence in an area often is not known until there is a confirmed livestock depredation. Ranchers and wildlife damage management experts need not wait for livestock depredations to occur before wolves …

Feral Swine, Michael P. Glow, Nathan P. Snow, Kurt C. Vercauteren
Wildlife Damage Management Technical Series
Feral swine (Sus scrofa; Figure 1), also known as feral hogs, feral pigs, wild pigs, wild boar, or other similar derivations, are a non-native species considered to be one of the most destructive invasive terrestrial vertebrates in North America. While feral swine populations remained relatively small and confined in the continental United States following initial introductions by European explorers during the 15th century, substantial range expansion has occurred across every geographical region of the United States (Figure 2). This expansion has primarily been attributed to human-mediated movements, predominately for the purpose of establishing populations for recreational hunting, and facilitated by …
Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison
Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison
MSU Graduate Theses
The purpose of this study was to aid the National Park Service at Wilson’s Creek National Battlefield with the reported habitat monitoring and management goals through vegetation and wildlife surveys within the park. I provided a description of two major habitat types that are of ecological concern, which included non-native ruderal grasslands and upland deciduous woodlands and forests. I evaluated small mammal communities to determine factors that may affect the detection of individual species and examined habitat associations with occupancy, as small mammals are good indicators of habitat quality. My study highlights the need to manage invasive species such as …
The Characterization Of A Vital Wisconsin Waterway: A Biological Assessment Of The Lower Fox River From 2006-2014, Emily L. Kiehnau
The Characterization Of A Vital Wisconsin Waterway: A Biological Assessment Of The Lower Fox River From 2006-2014, Emily L. Kiehnau
Lawrence University Honors Projects
The Lower Fox River has historically been used as a navigational crossroads, a waste disposal system, and source of hydroelectric power. Over the years, heavy use of the river has negatively affected water quality and the overall health of the system. Unhealthy rivers cannot function properly. Biological assessment based on animal surveys are often used to determine river health. I used data from the Lawrence University and Fox River Navigational System Authority invasive species-monitoring project to explore how the distribution of animals in the Fox River has changed over time and across locations. Monitoring surveys have taken place between June …
Greater Sandhill Crane: Research And Management In California Since 1978, Ronald W. Schlorff
Greater Sandhill Crane: Research And Management In California Since 1978, Ronald W. Schlorff
Proceedings of the North American Crane Workshop
The greater sandhill crane (Grus canadensis tabida) was added to the California list of threatened species in 1983, and the subspecies has been the subject of research and management actions instituted by the California Department of Fish and Game (hereafter Department). Since 1978, the Department has conducted research and recovery actions including periodic breeding ground and wintering area studies, population monitoring, participated in developing Pacific Flyway crane management plans, acquisition and management of key habitats on breeding and wintering grounds, and developed a draft greater sandhill crane recovery strategy. These tasks were accomplished with the assistance of crane …
