During the summers of 1992 and 1993, we conducted a survey of bats at Badlands National Park, South Dakota. Using mist nets, we captured bats and recorded species, sex, age class, and reproductive condition for each individual netted. We recorded five species, Myotis ciliolabrnm (n = 198), M. …

Morphometry of growth in hatchling striped plateau lizards (Iguanidae: Sceloporus virgatus)

Journal Articles | Contributor(s): Geoffrey R. Smith

I studied the ontogenetic development of body shape and the influence of food availability on the development of body shape in hatchling striped plateau lizards (Sceloporus uirgatus) over the first seven to eight weeks of their life. Body mass showed positive growth relative to snout-vent length. …

Monitoring and predicting traffic induced vertebrate mortality near wetlands

Reports | Contributor(s): J. Andrew DeWoody, Jamie M. Nogle, Melissa Hoover, Barny Dunning

Animal-vehicle collisions are undesirable to the general public, to drivers, to insurance providers, to biologists, and presumably to the animals themselves. However, traffic-induced mortality (―roadkill‖) is difficult to mitigate in large part because scientists lack the empirical data …

A description of the movement of the canine pelvic limb in three dimensions using an inverse dynamics method, and a comparison of two techniques to surgically repair a cranial cruciate ligament deficient stifle

Theses | Contributor(s): Jason Headrick, Darryl Millis

The purposes of the dissertation were: 1) to describe three-dimensional (3D) motion of the canine pelvic limb using an inverse dynamics method, and 2) to compare these motion patterns between normal, healthy dogs and those that have had their stifles stabilized by one of two surgical methods …

Studies on the helminth fauna of Alaska. XXXVI. Parasites of the wolverine, Gulo gulo L., with observations on the biology of Taenia twitchelli

Journal Articles | Contributor(s): Robert L. Rausch

Natural biotic relationships already had been severely disrupted in the United States by the time significant interest had developed in faunistic helminthology. Some mammalian species, particularly the larger carnivores, had been extirpated or were represented only by scattered individuals in the …

Neuromechanical control of locomotion in intact and incomplete spinal cord injured rats

Theses | Contributor(s): Anil Kumar Thota

Rodent models are being extensively used to investigate the effects of traumatic injury and to develop and assess the mechanisms of repair and regeneration. We present quantitative assessment of 2D kinematics of overground walking and for the first time 3D joint angle kinematics of all four limbs …

Estimating deer abundance in suburban areas with infrared-triggered cameras

Journal Articles | Contributor(s): Paul D. Curtis, Bazartseren Boldgiv, Peter M. Mattison, Jason R. Boulanger

Interactions between humans and white-tailed deer (Odocoileus virginianus) have become common, often resulting in management actions to mitigate negative impacts. Changes in population size are generally used to judge management actions. We examined deer population estimation techniques during 2 …

Genetic and dietary effects on chicken heterophil function and immune response to Salmonella enteritidis

Theses | Contributor(s): Sarah Beth Redmond, Susan J. Lamont (adviser)

The function of the chicken innate immune system against pathogens is affected by genetic background and immune modulating diet. Heterophils from broiler, Leghorn, and Fayoumi birds showed differential expression of immune genes when stimulated with Salmonella enteritidis (SE) bacteria, a zoonotic …

The effects of low protein during gestation on mouse pancreas development and beta cell regeneration

Theses | Contributor(s): Aaron Richard Cox, David Hill (adviser)

Effects of a low protein (LP) diet during gestation on the metabolism of rat offspring have been well characterized and leads to glucose intolerance in adulthood. It is unknown how LP impacts endocrine pancreas development in the mouse, or whether this affects future β-cell plasticity. …

A natural history study of Bufo a. americanus, the eastern American toad, and the phenology of spring breeders in southwest West Virginia

Theses | Contributor(s): Tomi Maria Bergstrom

Natural history traits have not been thoroughly collected and analyzed on the ―common hoptoad, Bufo a. americanus (eastern American toad) in West Virginia. Updating natural history information is important to understand the present population status (Jackson, 2001). I chose to have two study …

An integrative analysis of reproduction and stress in free-living male cottonmouths, Agkistrodon piscivorus

Theses | Contributor(s): Sean Patrick Graham

I conducted an integrative field study on male cottonmouths (Agkistrodon piscivorus), a common pitviper of the southeastern United States, to investigate the evolution of contrasting mating patterns in North American pitvipers (bimodal and unimodal annual patterns) and resolve conflicting …

Long-Term Research on Wolves in the Superior National Forest

Book Sections | Contributor(s): L. David Mech

The seeds for the blossoming of the wolf (Canis lupus) population throughout the upper Midwest were embodied in a long line of wolves that had persisted in the central part of the Superior National Forest (SNF) of northeastern Minnesota, probably since the retreat of the last glaciers. This line of …

The effect of exercise and diet on rat skeletal muscle phospholipid molecular species profile: an electrospray ionisation mass spectrometric analysis

Theses | Contributor(s): Todd W. Mitchell

Biological membranes separate cells from the external milieu and compartmentalise organelles within a cell, providing a specialised environment for many specific biochemical processes. They exist as bilayers of amphipathic lipids arranged with their hydrophobic moieties internalised and their …

The ecology of the peaks of otter salamander (Plethodon Hubrichti) in sympatry with the eastern red-backed salamander (Plethodon Cinereus)

Journal Articles | Contributor(s): Norman Reichenbach, Andrew Kniowski

The Peaks of Otter Salamander, Plethodon hubrichti, is found along a 19 km length of the Blue Ridge Mountains, Virginia, USA, often in sympatry with the Eastern Red-backed Salamander, P. cinereus. In a sympatric area of Bedford County, Virginia, we conducted a mark-recapture study on a 10 × 10 m …
