White-tailed deer (Odocoileus virginianus) are an important ecological, social, and economic resource in Mississippi. Studies have been conducted on expenditures by white-tailed deer hunters, but none have administered a research-based, economic impact assessment for white-tailed deer in Mississippi. The economic impacts and associated values of white-tailed deer in Mississippi through a selfministered mail questionnaire were examined to collect white-tailed deer hunter expenditure data during the 2003/2004 hunting season. Expenditures of white-tailed deer hunters were obtained from a mail survey (N = 1,257, 38.6% response rate) and were used in an input-output model to determine economic impacts for the State. Economic impacts generated from white-tailed deer hunting expenditures totaled $951.1 million for the 2003/2004 white-tailed deer hunting season. The value added component of the economic impact totaled $686.7 million and supported 43,964 full- and part-time jobs.

Twenty-four female fawns, weaned at 3.5 months of age, were divided into three groups and randomly assigned to one of four treatments with that group. High energy-high protein (HEHP), high energy-low protein (HELP), low energy-high protein (LEHP), and low energy-low protein (LELP) diets were the treatments used in 2x2 factorial design. High energy diets contained an average of 3064 kcal/kg digestible energy while low energy diets contained an average of 2507 kcal/kg digestible energy. Crude protein levels for high and low protein diets averaged 18.19 and 9.60 percent respectively. Eighteen fawns were included in the final analyses. Five fawns died of various causes during the course of the experiment while one fawn begun late on experiment was not included in any analysis. Fawns tended to reduce food consumption while weight gains decreased slowly during the course of the experiment. High energy diets caused a significant (p<0.05) increase in progestin concentrations over low energy diets. Progestin concentrations were significantly (p<0.05) higher during January (especially the first ⅓ of January) than any other month examined. Nine of 11 high energy animals and 0 of 8 low energy animals had progestin levels of at least 1.00 ng/ml during the experimental period. This was interpreted as indicating a higher incidence of ovulation and puberty in high energy animals. Protein level had no apparent effect on incidence of ovulation and puberty. Estrogen analysis was unsuccessful because of extremely low levels of estradiol in these fawns’ plasma. / Master of Science

This investigation was concerned with the incidence and degree of infection by <i>P. tenuis</i> in western Virginia deer herds (<i>Odocoileus virginianus</i>). Relatively little research has been done on <i>P. tenuis</i> in Virginia, especially in the western portion of the state. The objectives of this study were (1) to determine the distribution of pneumostrongylids in the White-tailed Deer in 7 western Virginia counties and (2) to correlate incidence and degree of infection by pneumostrongylids with deer age, sex, geographic location, and physical condition. Specimens were collected from Shenandoah Augusta, Bath, Rockrbidge, Botetourt, Giles, and Craig Counties. Collections were made on the first day of the 1963 deer season. Biologists and students from the department of Forestry and Wildlife at V.P.I and the Virginia Commission of Game and Inland Fisheries collected deer heads from hunters at check stations. A sample of 369 heads of both sexes was obtained. Three-hundred and nine deer heads, 230 does and 79 bucks, were examined for <i>P. tenuis</i>. Seventy-three per cent were infected. The majority of the worms (68%) were found on the dorsal surface of the brain. Overall range of infection was 1-13 worms. In addition, lung and fecal specimens were collected. Fifty per cent of the lung specimens were infected, but no larvae were found in the fecal material. There appears to be an equal likelihood of infection by <i>P. tenuis</i> in deer of either sex less than 1-1/2 years of age. There is also no difference between sexes in the severity of infections in deer less than 1-1/2 years old. Deer of either sex older than 3-1/2 years also have an equal likelihood of infection by <i>P. tenuis</i>, but females between 1-1/2 and 3-1/2 years are more likely to be infected than males. Females older than 1-1/2 years of age had significantly more worms per infection than males of the same age. There is no relationship between weight and incidence of infection in deer less than 1-1/2 years old or older than 3-1/2 years. However, a relationship does exist between the weight of the 1-1/2 to 3-1/2 years age group and the incidence of infection I nthat the heavier deer are more likely to be infected. The deer less than 1-1/2 years of age have lower incidence of infection than older deer and have fewer worms per infection than older deer. There was a significant difference in the incidence of infection between surveyed counties; however, there is no statiscally significant difference between counties and the severity of infections. Further research concerning pathogenic effects of <i>P. tenuis</i> on the White-tailed Deer is imperative prior to employment of any control methods. <i>P. tenuis.</i> may be a serious pathogen, but this research indicates that the deer-<i>P. tenuis</i> relationship is a relatively stable and common association with deer populations seldom adversely affected by the parasites. / M.S.

White-tailed deer (Odocoileus virginianus) (N=15) movements were determined with use of radio telemetry techniques to determine the utilization of corridor habitat on the Lake Ray Roberts Greenbelt Corridor (RRGC) in north central Texas. Home ranges were calculated using three estimation types. Male white-tailed deer tend to have home ranges twice that of female home ranges. Seasonal home ranges were largest during spring (Feb. - April) and fall (Aug. - Oct.) seasons. Males had greater seasonal variation in utilization than females. No statistically significant difference (p=0.24) between white-tailed deer locations when the RRGC experiences heavy human traffic compared to days when there is light human traffic. Linearity indices indicated home ranges less linear than expected (LI = 3.02). The RRGC should be maintained at its current status to provide a variety of vegetational types and protective cover for white-tailed deer and other wildlife of Denton County.

Recently, hunting and associated recreation have become an important business for Texas landowners. Most ranchers want to realize maximum net return from their investments. This study's objectives were to develop white-tailed deer (Odocoileus virginianus) and livestock enterprise budgets and to determine optimal economic combinations and levels of deer and livestock enterprises to maximize net returns. Questionnaires were mailed to landowners in the Edwards Plateau and South Texas Plains who purchased shooting preserve licenses in 1985. Five hundred and twenty-four ranchers responded {23.4%). Respondents were segregated by enterprises (deer, cattle, sheep, and Angora and Spanish goats) and a 5% random sample Has chosen from each group for personal interviews. Forty-two and eighteen ranchers in the Edwards Plateau and South Texas Plains, respectively, provided operational and financial information about their ranch enterprises. Typical ranch enterprise budgets were developed for four types of deer enterprises, three cattle enterprises, one sheep enterprise, two Angora goat enterprises, and one Spanish goat enterprise in the Edwards Plateau. In the South Texas Plains, enterprise budgets were developed for four types of deer enterprises and two cattle enterprises. Available resources, such as hectarage, labor, forage, and capital, were determined for typical ranches in both regions. The year deer enterprise was the most profitable deer enterprise in both regions, followed by the season, short-term/season, and short-term deer enterprises. The nanny-mutton-kid-breeding-mohair Angora goat enterprise was the most profitable livestock enterprise in the Edwards Plateau, while the cow-calf enterprise was the most profitable in the South Texas Plains. Linear programming was used to determine optimal combinations and levels of deer and livestock enterprises on typical Edwards Plateau and South Texas Plains ranches. The most profitable combination (in this case only one activity) in the Edwards Plateau was the nanny-mutton-kid- breeding Angora goat enterprise, which had an extremely high gross income due to high mohair prices and government subsidies. The year deer and cow-calf enterprises were the most profitable combination in the South Texas Plains. The most binding constraints on enterprise combination and level were labor, livestock investment, and spring and summer forage.

White-tailed deer (Odocoileus virginianus) numbers on the National Aeronautics and Space Administration's (NASA) Johnson Space Center (JSC) in Houston, Texas have increased in recent years and are a cause of urban-related accidents (e.g., deer-vehicle collisions, negative interation with humans). Safety personnel for the JSC are interested in reducing human-deer interaction by a reduction in overall population numbers. My overall study objectives were to (1) estimate population parameters for JSC deer, (2) develop a computer simulation model for the JSC deer, and (3) evaluate 2 management strategies to control JSC deer numbers a priori using the JSC deer model. The 2 management strategies I evaluated were the efficacy of SpayVac immunocontraceptive vaccine (sterilization) and trap and translocation (deer removal) efforts in managing white-tailed deer on JSC. In general, single treatments of removals or sterilization (less than 75 percent of female deer treated) were not effective in reducing population growth (R greater than 1). Approximately 50% of female deer needed to be removed annually to reduce population growth whereas approximately 25% of female deer needed to be treated annually with SpayVac for the same effects. A combination of trap and removals and sterilizations was effective in reducing population growth when applied to approximately 25% of the female population annually. I recommend the use of sterilization annually (25%) or a combination of sterilization and removal (25%) to achieve the goals of JSC in maintaining current deer numbers. Removing or sterilizing > 50% of the female deer annually caused the JSC deer population to decrease to a level near eradication.
