Effect Of Food Distribution On Northern Bobwhite Resource Selection, Rachel R. Gardner, John Maerz, Theron M. Terhune Ii, Ira B. Parnell, James A. Martin
Effect Of Food Distribution On Northern Bobwhite Resource Selection, Rachel R. Gardner, John Maerz, Theron M. Terhune Ii, Ira B. Parnell, James A. Martin
National Quail Symposium Proceedings
Supplemental feeding is a common management tactic used to increase survival and reproduction of northern bobwhite (Colinus virginianus; hereafter, bobwhite). Different supplemental feeding methods alter the distribution of resources across a landscape in unique ways and may influence the space use and resource selection of target species differently. Predators may concentrate their movements near fed sites, and different distributions of supplemental feed may encourage bobwhite to concentrate their movements closer to feed than other areas, thereby altering the potential for predator-prey interactions near feed. We used radio-tracked locations and movements in areas with stationary feeders (“feeder fed”) and …
Behavioral State-Specific Northern Bobwhite Chick Resource Selection, Justin N. Hill, Theron M. Terhune Ii, James A. Martin
Behavioral State-Specific Northern Bobwhite Chick Resource Selection, Justin N. Hill, Theron M. Terhune Ii, James A. Martin
National Quail Symposium Proceedings
Determining resource selection rates for all life stages of a species is critical to enable a holistic management approach that focuses on bolstering populations across all life stages. Moreover, tying these selection rates to specific life history needs (e.g., foraging, roosting, and loafing) can provide valuable information to guide management practices. Northern bobwhite (Colinus virginianus; hereafter, bobwhite), a gallinaceous species of North America, has experienced steady population declines throughout much of its range over the last 50 years. Although the species has been well studied, chick ecology is still relatively unknown. We studied bobwhite chick resource selection on …
Northern Bobwhite Demographics And Resource Selection Are Explained By Prescribed Fire With Grazing And Woody Cover In Southwest Missouri, Frank R. Thompson Iii, Mitch D. Weegman, Emily A. Sinnott, Alisha R. Mosloff, Kyle R. Hedges, Frank L. Loncarich, Thomas R. Thompson, Nicholas C. Burrell, Stasia Whitaker, David E. Hoover

National Quail Symposium Proceedings
Understanding the effects of landscape management on northern bobwhite (Colinus virginianus; hereafter, bobwhite) population growth requires information about seasonal- and stage-specific demographic parameters linked across the annual cycle. We review results to date from 3 years (2016–2018) of an intensive field study evaluating drivers of bobwhite population dynamics and resource selection during the breeding and non-breeding season in southwest Missouri, USA using data from adult and juvenile bobwhite fitted with radio-transmitters. Land cover of our study sites ranged from large blocks of native grasslands maintained with prescribed fire and grazing to more traditional management resulting in small patches …
The Role Of Wolves In Regulating A Chronic Non-Communicable Disease, Osteoarthritis, In Prey Populations, Sarah Hoy, John A. Vucetich, Rolf O. Peterson
The Role Of Wolves In Regulating A Chronic Non-Communicable Disease, Osteoarthritis, In Prey Populations, Sarah Hoy, John A. Vucetich, Rolf O. Peterson
Michigan Tech Publications
It is widely accepted that predators disproportionately prey on individuals that are old, weak, diseased or injured. By selectively removing individuals with diseases, predators may play an important role in regulating the overall health of prey populations. However, that idea is seldom tested empirically. Here we assess the extent that wolves (Canis lupus) select adult moose (Alces alces) in Isle Royale National Park on the basis of age-class and osteoarthritis, a chronic, non-communicable disease. We also assess how temporal variation in kill rates (on moose by wolves) were associated with the subsequent incidence of osteoarthritis in the moose population over …
Reproductive Rates, Kitten Survival, And Den Site Selection Of Bobcats (Lynx Rufus) In The Black Hills, South Dakota, Erin E. Morrison
Reproductive Rates, Kitten Survival, And Den Site Selection Of Bobcats (Lynx Rufus) In The Black Hills, South Dakota, Erin E. Morrison
Graduate Theses, Dissertations, and Problem Reports
The bobcat (Lynx rufus) is an important furbearer in South Dakota. However, management of bobcats can be difficult because of their elusive nature and lack of demographic information. In particular, managers lack information on abundance, survival, and reproductive rates necessary to ensure sustainable harvests and stable populations through time. Additionally, cause-specific mortality can provide insight into the factors influencing bobcat kitten survival rates, as well as reveal actions managers could take to improve survival. Bobcat resource selection can vary depending on spatial scale and it is important to understand how denning may result in different selection patterns at …
Feeling The Burn: Assessing The Effects Of Fire Severity On Elk Nutritional Resources And Resource Selection, Lauren Ashley Snobl
Feeling The Burn: Assessing The Effects Of Fire Severity On Elk Nutritional Resources And Resource Selection, Lauren Ashley Snobl
Graduate Student Theses, Dissertations, & Professional Papers
Wildfires in the western United States have been increasing in size and severity over the last several decades, and climate forecasts suggest a continued increase in wildfire activity in the future. Large-scale wildfires often burn in a mosaic-like pattern of varying fire severity creating a heterogenous landscape with concomitant effects on vegetation communities. By changing vegetative structure, fire severity potentially alters the availability and distribution of key resources for wildlife such as food and cover, ultimately influencing habitat use. However, the impact of fire on wildlife has frequently been treated as binary (i.e., burned vs unburned), and a deeper understanding …
