Contributor(s): Kevin Robert Messenger
Growth and age at reproductive maturity are life history attributes that play an important role in the development of proper management strategies. The Carolina Pigmy Rattlesnake, Sistrurus m. miliarius, is one of two dwarf rattlesnake species. The subspecies ranges from eastern NC to nearly the...
An Analysis of the Economic Factors and Changes in Land-Use Associated with the Transition to a Beef Feedlot System in Waterloo County
Contributor(s): Gary B. Griffith
Agricultural geography in Canada has been largely neglected as a field of geography until relatively recently. This is evidenced by several factors. First, until the mid 1960's, there were only two different agricultural geography courses offered in Canadian universities. Secondly, in that same...
Variables Influencing Nest Success of Eastern Wild Turkeys in Connecticut: Nesting Habitat, Home Range-Scale Fragmentation, and Nest Attentiveness
Contributor(s): Shelley M. Spohr, Daniel J. Harrison (adviser), Frederick A. Servello (adviser)
Nest success is the most important demographic parameter influencing rates of population change of eastern wild turkeys and many variables operating at multiple spatial and temporal scales may influence whether a nest is successful. Most studies of nest success and survival of turkeys have...
Shrimp Aquaculture and Aguadulce: A Broken Partnership
Contributor(s): Sylvia M. Bolanos, Richard Weisskoff (adviser)
A socio-economic impact study was conducted in Aguadulce, Panama to analyze the viability of the shrimp aquaculture industry. Two visits in 2004 and 2010 document the changes the industry underwent through the use of a survey and interviews of knowledgeable informants. Interviews were conducted...
Dried Distillers Grain with Solubles in Laying Hen and Pullet Rations
Contributor(s): Mahmoud Khaled Masa\'deh, Sheila E. Purdum (adviser)
The objective of this dissertation was to test different inclusion rates of dried distillers grains with solubles (DDGS) with or without enzyme supplementation. Study one was conducted to test DDGS at 0, 5, 10, 15, 20, or 25% on egg production parameter (24 through76 wk). As DDGS increased, egg...
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...
The ecology and behaviour of Varanus mertensi (Reptilia: Varanidae)
Theses | Contributor(s): Phillip James Mayes
This study examines numerous aspects of the ecology and behaviour of Merten’s Water Monitor, Varanus mertensi (Reptilia: Varanidae) including; daily behaviour, diet, foraging behaviour, reproductive seasonality and daily and long-term movements. Findings from over two years of field study of V....
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...
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...
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...
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...
Re-integrating crops and livestock in Maine: an economic analysis of the potential for and profitability of integrated agricultural production
Theses | Contributor(s): Aaron K. Hoshide, Stewart N. Smith (adviser)
This thesis examines the profitability of and sustainability indicators for potato and dairy farms in Maine integrating crops and livestock in two different ways. The first is inter-farm coupling, where two or more specialized producers are close enough to exchange manure applications for crops...
The effect of one-session exposure treatment on selective processing and explicit memory bias in snake- and spider-fearful participants
Theses | Contributor(s): Karen L. Stanley-Kime
Unlike the empirically supported phenomenon of anxiety-induced selective processing bias, research on congruent explicit memory bias is inconclusive; indeed, there is evidence for recall decrements of threat-relevant information. There is also a paucity of literature examining the effects of...
The effects of non-surgical interventions on osteoarthritis-like changes in the mouse knee
Theses | Contributor(s): Wendy K. Anemaet, Anna Plaas (adviser), William Haley (adviser)
Osteoarthritis (OA) is a debilitating condition affecting over 21 million persons in the United States. This number is expected to rise in the coming decades. Treatment approaches for OA focus on symptom modifying measures (i.e., pain relief) as disease modifying interventions do not currently...
Predictive measures of fetal distress in calves during delivery
Theses | Contributor(s): Kristin Elizabeth Hard, Howard Tyler (adviser)
The effect of birth stress on tongue color, length, and responsiveness was studied in fifty eight calves. The calves were monitored from stage 2 of parturition until birth. Tongue parameters (Tongue color, length, and responsiveness) were measured at two minute intervals. Immediately after birth...
Exploring sources of selection on the multimodal courtship displays of two sister species of wolf spiders: schizocosa crassipalpata and schizocosa bilineata
Theses | Contributor(s): Mitchel D. Bern, Eileen A. Hebets (adviser)
We examined multiple sources of selection on the multimodal courtship display of two sister species of wolf spiders, Schizocosa crassipalpata and Schizocosa bilineata. We first experimentally altered body condition in these two species by employing divergent diet treatments. We then tested for...
Sex, contamination and movement in an invasive fish
Theses | Contributor(s): Julie
Animal movement has had a long history of study in the fields of behavioural ecology and toxicology, but rarely is the ecological context of behaviour in toxicology directly addressed. To explore how movement might be influenced by both sex differences and habitat contamination, I conducted...
