Montezuma Quail In The Edwards Plateau Of Texas: Detection, Occurrence, And Habitat, Zachary J. Pearson, Eric D. Grahmann, Fidel Hernández, Robert Perez, Leonard A. Brennan, Humberto L. Perotto-Baldivieso
Montezuma Quail In The Edwards Plateau Of Texas: Detection, Occurrence, And Habitat, Zachary J. Pearson, Eric D. Grahmann, Fidel Hernández, Robert Perez, Leonard A. Brennan, Humberto L. Perotto-Baldivieso
National Quail Symposium Proceedings
Montezuma quail (Cyrtonyx montezumae) were historically found throughout nearly every county in the Edwards Plateau region of Texas, USA. Over the last century, shifting land use, reduction of fire on the landscape, and the subsequent encroachment of woody vegetation have constricted the distribution of Montezuma quail to a few counties in the southern portion of the Edwards Plateau. A renewed interest in management for Montezuma quail over the last decade has been met with a lack of information regarding their habitat requirements in this region. This lack of general information and increased sightings of this elusive species in …

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 …
Habitat Selection And Partitioning Among Darters In Two Tributaries Of The Clinch River, And Stream Restoration Effects On Substrate Profile, Daniel James Walker
Habitat Selection And Partitioning Among Darters In Two Tributaries Of The Clinch River, And Stream Restoration Effects On Substrate Profile, Daniel James Walker
Masters Theses
The group of fish referred to as darters is extremely biodiverse. Often, several closely related species will inhabit the same areas of streams, and prior research has investigated how these species may be partitioning the resources in low-order streams in which they are sympatric. The habitat partitioning of darters in two streams in the Clinch River system, Coal and Cove Creeks, was investigated. The study sites were picked due to their involvement in both physical and biological stream restoration efforts within the last several years, including the collection, translocation, and reintroduction of rainbow darters (Etheostoma caeruleum) from reference sites in …
Northern Bobwhite (Colinus Virginianus) Population Ecology On Reclaimed Mined Lands, Evan Philip Tanner
Northern Bobwhite (Colinus Virginianus) Population Ecology On Reclaimed Mined Lands, Evan Philip Tanner
Masters Theses
The northern bobwhite (Colinus virginianus) has experienced range-wide population declines for the past half century. The primary cause has been large-scale habitat loss and fragmentation. Through auspices of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), large tracts of early successional vegetation have been created throughout much of the bobwhite’s range that may be managed to increase usable space. Peabody WMA is a reclaimed coal mine in Western Kentucky where bobwhite have been present in the past. To better understand the dynamics of this population and how habitat on Peabody WMA influences these dynamics, my two …
Multiple Responses By Cerulean Warblers To Experimental Forest Disturbance In The Appalachian Mountains, Than James Boves
Multiple Responses By Cerulean Warblers To Experimental Forest Disturbance In The Appalachian Mountains, Than James Boves
Doctoral Dissertations
The Cerulean Warbler (Setophaga cerulea) is a mature forest obligate and one of the fastest declining songbird species in the United States. This decline may be related to a lack of disturbance within contemporary forests; however, the consequences of disturbance on the species have not been rigorously evaluated. Thus, we assessed multiple responses by Cerulean Warblers to a range of experimental forest disturbances across the core of their breeding range in the Appalachian Mountains. We quantified individual and population responses to these manipulations, and assessed the potential consequences of disturbance on the sexual signaling system. Male ceruleans were …
Population Abundance And Genetic Structure Of Black Bears In Coastal South Carolina, John Michael Drewry
Population Abundance And Genetic Structure Of Black Bears In Coastal South Carolina, John Michael Drewry
Masters Theses
Because of increasing frequency of bear sightings, vehicle collisions, and nuisance incidents in coastal South Carolina, the South Carolina Department of Natural Resources is developing a comprehensive black bear management plan. However, no reliable estimates of population abundance or density are available. I used genotypes of black bears determined from hair samples collected in Lewis Ocean Bay and Carvers Bay to estimate population abundance and density. I obtained hair samples from snares during 8 weekly sampling periods in 2008 and 2009. I used Huggins closed population models to estimate abundance and spatially explicit capture- recapture models to estimate density. Based …
