Assessing The Effects Of The Spring Hunting Season Start Date On Wild Turkey Seasonal Productivity And Hunter Behavior, Joseph Quehl
Assessing The Effects Of The Spring Hunting Season Start Date On Wild Turkey Seasonal Productivity And Hunter Behavior, Joseph Quehl
Masters Theses
Many states throughout the Southeast have documented declines in wild turkey (Meleagris gallopavo) harvest and estimates of recruitment in poult-per-hen ratios. Wild turkey populations are driven by seasonal productivity, so the decline in these parameters may indicate a decline in the overall population. One hypothesis as to why we are seeing a reduction in productivity and a potential population decline is that the spring hunting season is disrupting the reproductive cycle by harvesting too many males before they have had the opportunity to breed, or by harvesting dominant males and disrupting the social hierarchy of the flock. Our …
Cerulean Warbler Full Annual Cycle Ecology: Filling In Critical Knowledge Gaps, Douglas W. Raybuck
Cerulean Warbler Full Annual Cycle Ecology: Filling In Critical Knowledge Gaps, Douglas W. Raybuck
Doctoral Dissertations
Cerulean Warblers (Setophaga cerulea) are a declining migratory bird species of conservation concern that breed in mature hardwood forests of eastern North America and spend the stationary non-breeding period in the tropical Andes of South America. To reverse their >50-year population decline, a full annual cycle conservation strategy is needed. However, several important knowledge gaps have limited our understanding of this species’ full annual cycle ecology, including migration ecology, response to forest management on the breeding grounds, and basic ecology during the stationary non-breeding period in Andean forests. From geolocator data, we found a moderate pattern of migratory …
The Effects Of Urbanization On The Avian Gut Microbiome, Mae Berlow
The Effects Of Urbanization On The Avian Gut Microbiome, Mae Berlow
Doctoral Dissertations
The gut microbiome influences and is influenced by the host, and can affect the host organism by contributing to health, development and immunity. Similarly, the host can influence this community; it’s makeup can vary with host species, locality, diet, social stressors, and environmental stressors. Some of these environmental stressors have arisen due to human-induced rapid environmental change, like urbanization. The physiology and behaviors of organisms that are able to persist in urban environments are often different from their non-urban congeners. Nutrition, development, and immunity—all of which are affected by the gut microbiome—are important factors that can determine survival in urban …

Regional Assessment Of The Relationships Of Conservation Practices To Northern Bobwhite And Other Priority Grassland Bird Breeding Populations, Christopher Manuel Lituma
Regional Assessment Of The Relationships Of Conservation Practices To Northern Bobwhite And Other Priority Grassland Bird Breeding Populations, Christopher Manuel Lituma
Doctoral Dissertations
I documented populations of Northern Bobwhites (Colinus virginianus) and other priority grassland and early successional birds in the Central Hardwoods Bird Conservation Region (CHBCR), and determined whether conservation practices have been effective in positively impacting species occupancy and abundance. I designed and implemented a roadside survey by randomly locating five 15-km routes with 5-min unlimited distance point counts (30 counts/route), along secondary roads within Northern Bobwhite focal counties (n = 37) in the CHBCR. I also developed a survey to assess roadside biases for estimates of relative abundance (a), occupancy (ψ), detection probability (p), and associated …
Monitoring Grassland Bird Populations On Fort Campbell Military Reservation, Kentucky-Tennessee, With A Special Emphasis On Bachman’S Sparrow (Peucaea Aestivalis), Emily Vera Hockman
Monitoring Grassland Bird Populations On Fort Campbell Military Reservation, Kentucky-Tennessee, With A Special Emphasis On Bachman’S Sparrow (Peucaea Aestivalis), Emily Vera Hockman
Masters Theses
Grassland birds have declined more in the past four decades than any other group, primarily because of the suppression of ecological disturbance. Fort Campbell Military Reservation (FCMR) has maintained large amounts of grasslands and oak (Quercus spp.) savannas because of military training and prescribed fires, and supports many grassland bird populations. I established a survey route to investigate vegetation influencing occupancy of grassland birds with an emphasis on Bachman’s Sparrows (Peucaea aestivalis), and additionally described habitat selection of Bachman’s Sparrows on FCMR. Bachman’s Sparrow, Eastern Meadowlark (Sturnella magna), Henslow’s Sparrow (Ammodramus henslowii), and Orchard Oriole (Icterus spurius) occupancy were positively …
Avian Habitat Response To Grazing, Haying, And Biofuels Production In Native Warm-Season Forages In The Mid-South, Jessie Lee Birckhead
Avian Habitat Response To Grazing, Haying, And Biofuels Production In Native Warm-Season Forages In The Mid-South, Jessie Lee Birckhead
Masters Theses
Declines in grassland birds have been attributed to loss of habitat, habitat degradation, and changes in land management. In the Mid-South, pasture and hayfield management has focused on maintaining dense stands of non-native forages that do not provide suitable vegetative structure for grassland birds or northern bobwhite. Native warm-season grasses have been promoted for livestock forage and biofuels feedstock. However, little information exists on how these practices affect habitat for grassland songbirds or northern bobwhite in the Mid-South. We conducted a study of two cattle grazing treatments, two hay harvest treatments and a biofuels harvest treatment on vegetative structure for …
