Avian Ecology During Oak Savanna And Woodland Restoration In The Mid-South, Christine Ann Henderson
Avian Ecology During Oak Savanna And Woodland Restoration In The Mid-South, Christine Ann Henderson
Masters Theses
Disturbance-dependent ecosystems in the eastern United States have been declining since European settlement, and, in recent years, early-successional species have followed. My objective for this research was to determine if oak savanna and woodland restoration (i.e., overstory thinning and prescribed fire) was a viable method of recovering declining earlysuccessional species to the landscape of the Mid-South. At 3 sites, Catoosa Wildlife Management Area (CWMA; Tennessee), Green River Game Lands (GRGL; North Carolina), and Land Between the Lakes National Recreation Area (LBL; Tennessee), oak savanna and woodland restoration projects were established and maintained. Closed-canopy stands were thinned and a 2-year burn …
Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo
Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo
National Quail Symposium Proceedings
The decline in grassland birds is often associated with habitat loss due to intensity of conversion to agricultural lands and the alterations of natural disturbances. We sought to identify agricultural effects at differing scales that correlate to Texas grassland bird abundance, especially northern bobwhite (Colinus virginianus). Ninety-five roadside routes were surveyed in 20 Texas counties ranging from the Oklahoma border to the coastal plains. We conducted point counts in May and June from 2013 to 2016. To estimate the coarse effects of agriculture on bird abundance at a county level, we used number of cattle and area of …
Spatially Explicit Population Estimates Of The Florida Black Bear, Jacob Michael Humm
Spatially Explicit Population Estimates Of The Florida Black Bear, Jacob Michael Humm
Masters Theses
The Florida black bear (Ursus americanus floridanus) is currently comprised of 7 isolated subpopulations: Apalachicola, Eglin, Osceola, Ocala/St. Johns, Chassahowitzka, Highlands/Glades, and Big Cypress. The last statewide assessment of Florida black bear population dynamics was conducted by Simek et al. (2005) using traditional capture-markrecapture methods. The subspecies was removed from Florida’s List of State Threatened Species in 2012 contingent upon the formulation of a management plan that would maintain viable subpopulations of black bears in suitable habitat. Accurate population estimates for each of the remaining black bear subpopulations in Florida were needed to achieve the management goals of …
