Description Of A Poorly Differentiated Carcinoma Within The Brainstem Of A White Whale (Delphinapterus Leucas) From Magnetic Resonance Images And Histological Analysis, Sam H. Ridgway, Lori Marino, T. P. Lipscomb
Description Of A Poorly Differentiated Carcinoma Within The Brainstem Of A White Whale (Delphinapterus Leucas) From Magnetic Resonance Images And Histological Analysis, Sam H. Ridgway, Lori Marino, T. P. Lipscomb
Veterinary Science and Medicine Collection
In this study we used magnetic resonance imaging (MRI) to investigate neuroanatomical structure in the brain of a white whale (Delphinapterus leucas) that died from a large tumor within the brainstem. This specimen was also compared with a normal white whale brain using MRI. MRI scans of the white whale specimen show how the tumor deformed surrounding brain structure. Histopathological analysis indicated a poorly differentiated carcinoma of uncertain origin. These analyses demonstrate the usefulness of supplementing histological analyses of pathology with studies of gross morphology facilitated by MRI.

Endogenous Gonadal Hormone Exposure And Bone Sarcoma Risk, Dawn M. Cooley, Benjamin C. Beranek, Deborah L. Schlittler, Nita W. Glickman, Lawrence T. Glickman, David J. Waters
Endocrinology Collection
Although experimental and clinical evidence suggest that endogenous sex hormones influence bone sarcoma genesis, the hypothesis has not been adequately tested in an appropriate animal model. We conducted a historical cohort study of Rottweiler dogs because they frequently undergo elective gonadectomy and spontaneously develop appendicular bone sarcomas, which mimic the biological behavior of the osteosarcomas that affect children and adolescents. Data were collected by questionnaire from owners of 683 Rottweiler dogs living in North America. To determine whether there was an association between endogenous sex hormones and risk of bone sarcoma, relative risk (RR) of incidence rates and hazard ratios …
Predators And Life Histories Shape Lestes Damselfly Assemblages Along A Freshwater Habitat Gradient, Robby Stoks, Mark A. Mcpeek
Predators And Life Histories Shape Lestes Damselfly Assemblages Along A Freshwater Habitat Gradient, Robby Stoks, Mark A. Mcpeek
Dartmouth Scholarship
Survey data from New England showed that assemblages of Lestes dam- selflies are organized along the entire gradient of pond permanence and predator presence. One assemblage occupies vernal ponds lacking large dragonfly predators and fish; four are largely confined to temporary ponds that typically contain dragonfly predators; one dom- inates fishless permanent ponds and lakes where dragonflies are the top predators; and one dominates permanent ponds and lakes where fish are the top predators. We determined the role of life history and predation in maintaining this striking pattern by conducting a series of transplant experiments in the field and a …
Impact Of The Agricultural Sector On The Arkansas Economy, H. L. Goodwin Jr., Jennie Popp, Wayne Miller, Gina Vickery, Z. Clayton-Niederman
Impact Of The Agricultural Sector On The Arkansas Economy, H. L. Goodwin Jr., Jennie Popp, Wayne Miller, Gina Vickery, Z. Clayton-Niederman
Research Reports and Research Bulletins
Agriculture historically has been one of the primary sectors of the Arkansas economy. Agriculture is defined as the sum of agricultural, forestry, and fisheries production and processing activities unless otherwise specified. Not only does agriculture contribute to the economy through direct agricultural production and added value processing, it also plays an important role through the economy’s other sectors. Utilizing data from the United States Bureau of Economic Affairs and the State of Arkansas, the economic impact of agriculture on the Arkansas economy was estimated for the latest year available, 1999. Gross State Product (GSP) information for Arkansas was compared with …

Mitochondrial Dna And The Origins Of The Domestic Horse, Thomas Jansen, Peter Forster, Marsha Levine, Hardy Oelke, Matthew Hurles, Colin Renfrew, Jürgen Weber, Klaus Olek
Mitochondrial Dna And The Origins Of The Domestic Horse, Thomas Jansen, Peter Forster, Marsha Levine, Hardy Oelke, Matthew Hurles, Colin Renfrew, Jürgen Weber, Klaus Olek
Genetics Collection
The place and date of the domestication of the horse has long been a matter for debate among archaeologists. To determine whether horses were domesticated from one or several ancestral horse populations, we sequenced the mitochondrial D-loop for 318 horses from 25 oriental and European breeds, including American mustangs. Adding these sequences to previously published data, the total comes to 652, the largest currently available database. From these sequences, a phylogenetic network was constructed that showed that most of the 93 different mitochondrial (mt)DNA types grouped into 17 distinct phylogenetic clusters. Several of the clusters correspond to breeds and/or geographic …
A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer
A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer
School of Natural Resources: Dissertations, Theses, and Student Research
The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …
Within-Litter Birth Weight Variation In The Domestic Pig And Its Relation To Pre-Weaning Survival, Weight Gain, And Variation In Weaning Weights, Barry N. Milligan, David Fraser, Donald L. Kramer
Within-Litter Birth Weight Variation In The Domestic Pig And Its Relation To Pre-Weaning Survival, Weight Gain, And Variation In Weaning Weights, Barry N. Milligan, David Fraser, Donald L. Kramer
Ontogeny Collection
To determine the relationship between within-litter birth weight variation and pre-weaning survival and weight gain, and to provide practical guidance on fostering low-birth-weight piglets, we analyzed piglet survival and weight gain in litters of piglets from 52 sows followed through eight consecutive parities. Litters with high variation in birth weight had more deaths, especially if the litter’s mean birth weight was low. High variation in birth weight was also associated with high variation in weaning weight, but was not significantly related to mean weaning weight. Piglets with birth weights well below the range of most of the litter (‘low-birth-weight piglets’) …
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 …
Physiology And Behavior Of Dogs During Air Transport, Renée Bergeron, Shannon L. Scott, Jean-Pierre Émond, Florent Mercier, Nigel J. Cook, Al L. Schaefer
Physiology And Behavior Of Dogs During Air Transport, Renée Bergeron, Shannon L. Scott, Jean-Pierre Émond, Florent Mercier, Nigel J. Cook, Al L. Schaefer
Stress Collection
Twenty-four beagles were used to measure physiological and behavioral reactions to air transport. Each of 3 groups of 4 sedated (with 0.5 mg/kg body weight of acepromazine maleate) and 4 non-sedated (control) dogs was flown on a separate flight between Montreal, Quebec, and Toronto, Ontario, after being transported by road from Quebec City to Montreal. Saliva and blood samples were taken before ground and air transport and after air transport. The heart rate was monitored during the whole experiment except during ground transport, and behavior was monitored by video during air transport. Sedation did not affect any of the variables …
Social Learning Of A Novel Avoidance Task In The Guppy: Conformity And Social Release, Culum Brown, Kevin N. Laland
Social Learning Of A Novel Avoidance Task In The Guppy: Conformity And Social Release, Culum Brown, Kevin N. Laland
Sentience Collection
Studies of social learning suggest that many animals are disproportionately likely to adopt the behavior of the majority, and that this conformist transmission hinders the spread of novel behavioural variants. However, novel learned behaviour patterns regularly diffuse through animal populations. We propose a hypothesis, termed the ‘social release hypothesis’, that resolves these apparently conflicting findings by suggesting that animals are released from conforming to traditional behaviour in the absence of demonstrators. We investigated the role of pretrained, female demonstrator guppies, Poecilia reticulata, in influencing the escape response of untrained females to an artificial predator. Naïve ‘observer’ guppies were given the …
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.

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, …

My goals were to contact and/or visit other schools and facilities in order to increase articulations and examine similarities and differences between programs. I also wanted to determine current trends and developments in the equine industry, particularly from teaching and job placement perspectives. I wanted to investigate therapeutic riding since I had received many inquiries about such opportunities, both from students and community members. I also wanted to work with horses, attend shows, workshops and seminars to update my practical and academic expertise. When it was practical, I attended events within reasonable driving distance and grouped visits.

A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full
A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full
All HMC Faculty Publications and Research
The individual muscles of a multiple muscle group at a given joint are often assumed to function synergistically to share the load during locomotion. We examined two leg extensors of a running cockroach to test the hypothesis that leg muscles within an anatomical muscle group necessarily manage (i.e. produce, store, transmit or absorb) energy similarly during running. Using electromyographic and video motion-analysis techniques, we determined that muscles 177c and 179 are both active during the first half of the stance period during muscle shortening. Using the in vivo strain and stimulation patterns determined during running, we measured muscle power output. …

Convergence Of Complex Cognitive Abilities In Cetaceans And Primates, Lori Marino
Convergence Of Complex Cognitive Abilities In Cetaceans And Primates, Lori Marino
Sentience Collection
What examples of convergence in higher-level complex cognitive characteristics exist in the animal kingdom? In this paper I will provide evidence that convergent intelligence has occurred in two distantly related mammalian taxa. One of these is the order Cetacea (dolphins, whales and porpoises) and the other is our own order Primates, and in particular the suborder anthropoid primates (monkeys, apes, and humans). Despite a deep evolutionary divergence, adaptation to physically dissimilar environments, and very different neuroanatomical organization, some primates and cetaceans show striking convergence in social behavior, artificial ‘language’ comprehension, and self-recognition ability. Taken together, these findings have important implications …
Cognitive And Communicative Abilities Of Grey Parrots, Irene M. Pepperberg
Cognitive And Communicative Abilities Of Grey Parrots, Irene M. Pepperberg
Sentience Collection
Grey parrots (Psittacus erithacus) solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Given that the psittacine brain is organized very differently from that of mammals, these results have intriguing implications for the study and evolution of vocal learning, communication, and cognition.
Chimpanzees (Pan Troglodytes) Recognize Spatial And Object Correspondences Between A Scale Model And Its Referent, Valerie A. Kuhlmeier, Sarah T. Boysen
Chimpanzees (Pan Troglodytes) Recognize Spatial And Object Correspondences Between A Scale Model And Its Referent, Valerie A. Kuhlmeier, Sarah T. Boysen
Sentience Collection
In the present study, the contributions of spatial and object features to chimpanzees’ comprehension of scale models were examined. Seven chimpanzees that previously demonstrated the ability to use a scale model as an information source for the location of a hidden item were tested under conditions manipulating the feature correspondence and spatial-relational correspondence between objects in the model and an outdoor enclosure. In Experiment 1, subjects solved the task under two conditions in which one object cue (color or shape) was unavailable, but positional cues remained. Additionally, performance was above chance under a third condition in which both types of …

In Search Of King Solomon’S Ring: Cognitive And Communicative Studies Of Grey Parrots (Psittacus Erithacus), Irene M. Pepperberg
Sentience Collection
During the past 24 years, I have used a modeling technique (M/R procedure) to train Grey parrots to use an allospecific code (English speech) referentially; I then use the code to test their cognitive abilities. The oldest bird, Alex, labels more than 50 different objects, 7 colors, 5 shapes, quantities to 6, 3 categories (color, shape, material) and uses ‘no’, ‘come here’, wanna go X’ and ‘want Y’ (X and Y are appropriate location or item labels). He combines labels to identify, request, comment upon or refuse more than 100 items and to alter his environment. He processes queries to …
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.

Effect Of Hydrogen Peroxide On Protein Degradation Of Feather Meal, C.A. Löest, C.M. Coetzer, Evan C. Titgemeyer, James S. Drouillard
Effect Of Hydrogen Peroxide On Protein Degradation Of Feather Meal, C.A. Löest, C.M. Coetzer, Evan C. Titgemeyer, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Protein degradation of feather meal treated with hydrogen peroxide was evaluated using the in situ bag technique. Bags containing untreated feather meal or feather meal treated with 1.4, 2.5, 2.7, 5.0, or 7.0% hydrogen peroxide (g/100 g feather meal, as fed basis) at various pH and times of heating (55oC) were suspended in the rumen of a cannulated steer for 12 hours. Protein degradabilities of feather meal treated with 2.5 and 2.7% peroxide were only 12 to 19% greater than untreated feather meal, but feather meal treated with 5% peroxide had protein degradabilities 56 to 67% greater than untreated feather …

Use Of Organic Acids For Control Of Clostridium Perfringens In Cooked Vacuum-Packaged Ground Beef Products Subjected To Substandard Cooling Procedures, J.R. Sabah, T. Harshavardhan, James L. Marsden, Daniel Y.C. Fung
Kansas Agricultural Experiment Station Research Reports
This study determined the ability of Clostridium perfringens spores to germinate and grow after different organic acid treatments in vacuum packaged cooked ground beef subjected to substandard (slow) cooling. Meat samples were inoculated with a three-strain cocktail of C. perfringens spores (ATCC 10388, NCTC 8238, and NCTC 8239), then vacuum-packaged, cooked in a water bath to 167°F internal temperature, and held 20 min. The water bath temperature was then lowered to 130°F, and samples were cooled from 130°F to 45°F over 18 hr. Samples were taken after inoculation, after cooking, and after cooling. In the event of substandard cooling, sodium …
Effects Of Tallow And Ground Flaxseed On Sensory And Color Characteristics Of Ribeye Steaks, H.J. Labrune, K.A. Hachmeister, Donald H. Kropf, James S. Drouillard, Michael E. Dikeman
Effects Of Tallow And Ground Flaxseed On Sensory And Color Characteristics Of Ribeye Steaks, H.J. Labrune, K.A. Hachmeister, Donald H. Kropf, James S. Drouillard, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Forty-eight ribeye steaks from steers fed diets containing steam-flaked corn (SFC), steam-flaked corn with tallow (SFC/Tallow), or steam-flaked corn with rolled flaxseed (Flax) were used to evaluate the effects of dietary fat on sensory traits, retail display color stability, and fatty acid composition. Steaks from Flax-fed steers had increased deposition of α linolenic acid (C18:3n3, an omega-3 fatty acid; P<0.01) and developed a detectable off-flavor (P<0.05) when compared to those of cattle fed SFC and SFC/Tallow. There were no differences in tenderness, juiciness, or flavor intensity (P>0.10) among the three treatments. Steaks from cattle fed SFC retained a desirable color longer than those from cattle fed Flax (P<0.05) which may be attributable to premature lipid oxidation in steaks from cattle fed Flax. This study suggests that altering the fat in the diet may affect flavor and color stability of the meat. Feeding flaxseed can effectively alter composition of carcass tissues to yield beef that is high in omega-3 fatty acids, which may lead to premature lipid oxidation.

Will Blade Tenderization Decrease Iridescence In Cooked Beef Semitendinosus Muscle?, E. Obuz, Donald H. Kropf
Kansas Agricultural Experiment Station Research Reports
Ten beef semitendinosus muscles were divided into three sections, which were randomly assigned to one of three blade tenderization treatments (control-zero, one, or two times). Blade-tenderized muscles were cooked in a forced-air convection oven at 325° to 145°F and held for 1 min. Cooked muscles were chilled overnight at 38°F and sliced by a sharp knife. Panelists (n=19) evaluated iridescence intensity on a five-point scale (0=no iridescence, 5=very strong) and extent of iridescence (0=no iridescence, 5=81-100% affected area). Blade tenderization decreased (P<0.05) iridescence intensity from 2.37 to 2.02 and extent of iridescence from 2.18 to 1.83 (control zero vs. two passes). Cooking loss increased (P<0.05) with blade tenderization (30.4% control, 32.6% one pass, 33.7% two passes). Blade tenderization has a moderate effect on reducing iridescence.
