Winter Survival And Resource Use Of Translocated Northern Bobwhite In The Mid-Atlantic United States, Kaili Stevens, Christopher K. Williams, Theron Terhune, Philip Coppola, John Parke, John Cecil Sep 2022

Winter Survival And Resource Use Of Translocated Northern Bobwhite In The Mid-Atlantic United States, Kaili Stevens, Christopher K. Williams, Theron Terhune, Philip Coppola, John Parke, John Cecil

National Quail Symposium Proceedings

Northern bobwhite (Colinus virginianus; hereafter, bobwhite) in the Mid-Atlantic United States have been experiencing precipitous population declines due to a combination of habitat deterioration, urban and suburban sprawl, change in forest management regimes, and farming practices. In recent years, restocking of bobwhite through translocation efforts has gained interest to rebuild local populations. However, empirical studies are warranted to understand the limitations of translocation as it relates to its potential use for long-term population recovery and persistence in this region. Further, few studies nation-wide have evaluated resource use and survival during the non-breeding season on translocated sites. As such, …


Effect Of Food Distribution On Northern Bobwhite Resource Selection, Rachel R. Gardner, John Maerz, Theron M. Terhune Ii, Ira B. Parnell, James A. Martin Sep 2022

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 …


Estimating Giraffe (Giraffa Camelopardalis) Population Size And Survival Rates In South Luangwa Valley, Zambia, Samantha Phillips Aug 2022

Estimating Giraffe (Giraffa Camelopardalis) Population Size And Survival Rates In South Luangwa Valley, Zambia, Samantha Phillips

All NMU Master's Theses

Giraffe populations across their range have declined significantly over the past 40 years. Recent studies of these declines noted that conservation efforts often lack basic population estimates and descriptions of demographic parameters such as sex- and age-specific survival rates. I addressed those research needs for a geographically-isolated population of giraffes (Giraffa camelopardalis) in South Luangwa Valley, Zambia. During 2016 to 2018, collaborators opportunistically photographed giraffes throughout South Luangwa National Park and adjacent Lupande and Lumimba Game Management Areas. Given that each giraffe has a unique spotting pattern, I created a photo inventory of the population and developed an …


Effects Of Snake Fungal Disease On The Survival And Growth Of The Queensnake (Regina Septemvittata), Andrew Jerome Ibach Jan 2022

Effects Of Snake Fungal Disease On The Survival And Growth Of The Queensnake (Regina Septemvittata), Andrew Jerome Ibach

Theses and Dissertations--Forestry and Natural Resources

Having only emerged as a threat to snakes in 2006, relatively little is known of snake fungal disease’s (SFD) impacts on demographic processes, particularly survival and growth. I used data from an extensive capture-mark-recapture study to examine survival and growth in central Kentucky Queensnake (Regina septemivittata) populations. I found that diseased snakes and healthy snakes possessed similar monthly survival estimates (SFD positive 0.9687, 95% CI 0.8444 to 0.9944; SFD negative 0.8735, 95% CI 0.7518 to 0.9402) and that disease state transition probability from SFD negative to SFD positive, and SFD positive to SFD negative were also similar (N-P …
