Evaluation Of Carfentanil And Xylazine For Immobilization Of White-Tailed Deer, Bradley F. Miller
Evaluation Of Carfentanil And Xylazine For Immobilization Of White-Tailed Deer, Bradley F. Miller
Masters Theses
From October 2001 until January 2002 captive wild white-tailed deer (Odocoileus virginianus) held at the University of Georgia Daniel B. Warnell School of Forest Resources Whitehall Deer Research Facility were immobilized with a combination of carfentanil (carfentanil citrate) and xylazine (xylazine hydrochloride) to 1) determine and evaluate an optimum and safe dose for carfentanil/xylazine in white-tailed deer and 2) compare immobilization parameters and physiological effects of carfentanil/xylazine to Telazol®/xylazine. Animals were given intramuscular injections of 10 mg of xylazine and one of four different levels of carfentanil 0.5, 1.0, 1.5, and 2.0 mg. A carfentanil dose of 1.2 …
Movement Patterns Of Phrynosoma Mcallii And Phrynosoma Platyrhinos In Response To Substrate Texture, Daniel H. Foley Iii
Movement Patterns Of Phrynosoma Mcallii And Phrynosoma Platyrhinos In Response To Substrate Texture, Daniel H. Foley Iii
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During the summers of 1999 and 2000 the apparent habitat partitioning of two species of sympatric horned lizards was investigated at the Barry M. Goldwater Bombing Range near Yuma, Arizona. The flat-tailed horned lizard, Phrynosoma mcallii, and the desert horned lizard, P. platyrhinos, overlap in range in portions of the Sonora desert in the southwestern United States. However, upon finer scale examination, it appeared that these horned lizards were partitioning the available habitat according to soil substrate texture. Phrynosoma mcallii appeared to be exclusively found in areas of fine, loose, wind-blown sands, in contrast to P. platyrhinos, …
Winter Ecology Of Cooper’S Hawks On Ames Plantation, Tennessee, Laura A. Lake
Winter Ecology Of Cooper’S Hawks On Ames Plantation, Tennessee, Laura A. Lake
Masters Theses
Cooper’s hawks (Accipiter cooperii) were listed by Ganier (1933) as fairly common permanent residents of western Tennessee during the early 1900’s, but populations declined during the 20th Century presumably because of habitat changes, shooting, and effects of pesticides on reproduction (Newton 1979). Breeding bird survey data for Tennessee suggest that Cooper’s hawk populations are increasing (+4.6% increase/year, 1966-2000), although sample sizes are too small for significant trends (P = 0.39, Sauer et al. 2001). Nicholson (1997), in the Tennessee Breeding Bird Atlas completed during the early 1990's, still described Cooper’s hawks as uncommon permanent residents.

Phylogenetic Structure Of Two Central Mexican Centruroides Species Complexes, William Ian Towler
Phylogenetic Structure Of Two Central Mexican Centruroides Species Complexes, William Ian Towler
Theses, Dissertations and Capstones
Central Mexico is home to numerous species of highly toxic Centruroides scorpions. Two species complexes C. infamatus, (C.L. Koch, 1844), and C. limpidus (Karsch, 1879) typify the complex relationships that exist between and within the complexes. Their existing taxonomic status is based on morphological features such as coloration and morphosculpture. A complete and modern study of these scorpions does not exist, and is needed. In an attempt to clarify the status and relationship between these complexes we initiated a molecular based approach applying mitochondrial gene markers (16S and CO1). This study confirms two divergent clades within C. infamatus; divergence rate …
Comparisons In Morphology, Reproductive Status, And Feeding Ecology Of Plethodon Cinereus At High And Low Elevations In West Virginia, Mizuki Takahashi
Comparisons In Morphology, Reproductive Status, And Feeding Ecology Of Plethodon Cinereus At High And Low Elevations In West Virginia, Mizuki Takahashi
Theses, Dissertations and Capstones
To develop effects of elevation on morphological features, reproductive status, and feeding ecology of Plethodon cinereus in West Virginia, overall comparisons between high (>4000 ft) and low (<1260 ft) elevation populations were made. Adult P. cinereus from high elevations were smaller in SVL (female: p=0.003, male: p<0.001), but stored larger amounts of fat (female: p=0.041, male: p=0.006) in their tails than fromlow elevations. Larger amounts of tail fat could be an adaptation to harsh environments at high elevations. It was determined that in West Virginia, where as females at low elevations oviposit annually, females at high elevations oviposit biennially. Stomach content analysis revealed that salamanders at high elevations were confronted by food shortage. Because of less prey availability and longer winters at high elevations, salamanders at high elevations attained the smaller body size than at low elevations and could not obtain sufficient energy in 1 year to yolk a clutch.
