Spatial Learning Of An Escape Task By Young Corn Snakes, Elaphe Guttata Guttata, David A. Holtzman, Terrence W. Haris, Guillermo Aranguren, Elizabeth Bostock

Biology Faculty Publications and Presentations

Spatial learning is critical to most animals for many behaviours necessary to survival. In vertebrates, most studies on spatial learning and memory have been conducted in mammalian and avian species with few studies on reptiles. We examined spatial learning in the corn snake, Elaphe guttata guttata by training 17 young snakes to find the one open shelter in an eight-hole arena, where the entrance was not visible from the arena surface. Over a 16-trial, 4-day training period, snakes showed (1) a significant decrease in the mean latency to the goal, (2) a significant decrease in the mean total distance travelled, …

Attitudes To Biotechnology And Genetically Modified Food : A Review, Juliana Rose Cannon

Theses : Honours

Debate surrounds the introduction of new biotechnological applications such as genetically modified food (GMF). With this in mind a critical review of the debate, it's emerging themes, and approaches to measurement was undertaken. The intention of this review was to argue that while existing empirical measures have advanced our understanding of attitudes to GMF, they are limited both conceptually and methodologically. Overall, the validity and reliability of research support was compromised. Conceptually, attitudes to GMF were composed of a number of potential dimensions that have yet to be measured. Adherence to sound scale construction techniques may facilitate more reliable and …

Comparative Evaluation Of Cotesia Flavipes And C. Sesamiae (Hymenoptera: Braconidae) For The Management Of Chilo Partellus (Lepidoptera: Pyralidae) In Kenya, M. N. Sallam, W. A. Overholt, E. Kairu

All Peer-Reviewed Publications

Cotesia flavipes Cameron, a gregarious larval endoparasitoid native to the Indo-Australian region, was imported from Pakistan and released in Kenya in 1993 for management of the exotic stemborer, Chilo partellus (Swinhoe). Recent reports confirmed the successful establishment of the parasitoid in three locations in Kenya and in northern Tanzania. Functional response studies on this parasitoid and an indigenous congener, Cotesia sesamiae (Cameron), indicated that C. flavipes had a higher searching ability and attacked more larvae when Chilo partellus was the host. When a native stemborer, Sesamia calamistis Hampson, was the host, there was no significant difference between numbers attacked by …

Religiosity And Physical Fitness: A Study Of Middle-Aged Mormon Men, Janette Olsen

Theses and Dissertations

Research has related both physical fitness and religiosity to health. This study combined these ideas and examined the relationship between religiosity and physical fitness among middle aged Mormon men (n=110). Mormons are an ideal population for study because of their strict health code. Fitness variables were grip strength, waist/hip ratio, body mass index (BMI) and estimated maximal oxygen uptake (VO2max). A questionnaire assessed level of religiosity and separated subjects into two groups: highly religious (n=35) and less religious (n=14). Moderately religious subjects (n=61) were omitted. A one way ANOVA (between-groups design) found no significant differences in fitness variables between groups. …

Educational And Occupational Aspirations Of Rural High School Seniors In The Private And Public Schools In Northwest Iowa, Duane Bajema

Faculty Work Comprehensive List

Research has suggested that rural youth have lower educational and occupational aspirations than their nonrural counterparts, and they may experience barriers to educational and occupational attainment. Discrepancies and barriers that may exist have implications for educational policy and educational planning.

Seventeen rural high schools in northwest Iowa were examined; thirteen public and four private schools. Rural high school students were studied to examine their perceptions concerning potential educational and occupational barriers. Student characteristics and qualities were examined based on where the student lived and the type of school they attended. Students who had been involved in the agricultural curricula in …

When That Tune Runs Through Your Head: A Pet Investigation Of Auditory Imagery For Familiar Melodies, Andrea R. Halpern, Robert J. Zatorre

Faculty Journal Articles

The present study used positron emission tomography (PET) to examine the cerebral activity pattern associated with auditory imagery forfamiliar tunes. Subjects either imagined the continuation of nonverbaltunes cued by their first few notes, listened to a short sequence of notesas a control task, or listened and then reimagined that short sequence. Subtraction of the activation in the control task from that in the real-tune imagery task revealed primarily right-sided activation in frontal and superior temporal regions, plus supplementary motor area(SMA). Isolating retrieval of the real tunes by subtracting activation in the reimagine task from that in the real-tune imagery task …

A Comparison Of Nutritional Knowledge, Eating Attitudes, Training Regimens, And Body Composition Between Normal And Abnormal Menstruating Female Adolescent Cross Country Athletes, Dena Maureen Block

Masters Theses

The purpose of this study was to compare factors that may influence menstrual irregularities of female adolescent high school cross-country runners, ranging from 13-18 years of age. A survey was utilized to determine the subjects age, year in school, exercise history, menstrual history, and training regimens and where the subjects sought nutritional information. The groups were separated according to their current menstrual status. One group (normal) consisted of subjects who currently had a normal menstrual cycle for at least one year (n=17), while the other group (abnormal) (n=18) experienced an irregular menstrual cycle.

A twenty item questionnaire was administered to …

The Effect Of Different Warm-Downs On Heart Rate Recovery And Muscular Lactic Acid Removal, Alison Jean Perkins

Honors Theses

Competitive swimmers and coaches have had varying ideas about what exercises constitute an appropriate warm-down. However, there is much agreement about what a warm-down should achieve. A good warm-down should do three things. First, a warm-down should be successful in returning the swimmer's elevated heart rate to the resting heart rate level in a relatively short period of time. Second, the warm-down should flush lactic acid out of the muscles as quickly as possible, and restore blood lactate to baseline levels. Finally the warm-down should contribute to improved athletic performances.

In this experiment, it was expected that a decreasing intensity …

The Effects Of Aerobic And Resistance Training On Mood State And Self-Esteem In Cardiac Rehabilitation, Cyndee M. Lee

Head Stabilisation During Running In Place Of Children With Varying Motor Proficiency Levels, Craig Atkins

Theses : Honours

Understanding head motion in children may contribute to development of effective strategies to improve coordination of children. The purpose of this study was to investigate head motion in children during stationary running. Twelve healthy 8-year-old children participated in this study and underwent a running proficiency test based on the Test for Gross Motor Proficiency (TGMO). Subjects were then videotaped while running for one minute "on the spot". Reflective markers were digitised for analysis of head motion relative to the external environment, and relative to the trunk. Resultant and component head angular velocities were calculated for each subject over five consecutive …

Development Of Odour-Baited Traps For Glossina Swynnertoni (Diptera: Glossinidae), P. N. Ndegwa, S. Mihok

All Peer-Reviewed Publications

Three new prototype traps, (S1-S3), were developed during studies of the behavioural ecology of Glossina swynnertoni Austen in Kenya and Tanzania. The traps were compared in latin square experiments relative to the regular biconical trap as a standard and a selection of other conventional tsetse traps. Observations were also made on fly behaviour in the vicinity of traps using electric nets and sticky materials. When baited with acetone and 1-octen-3-ol, the S1 trap was 3.5 times as effective in catching G. swynnertoni in Kenya as the biconical trap. In Tanzania, the relative performance of the S1 and biconical traps differed; …

Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller

Dissertations and Theses @ UNI

The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …

The Behavior Of Preweanling Pups Exposed To Valproate In-Utero, Wayne Briner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Valproate is a known human and animal teratogen that produces neural-tube defects. Valproate is also known to produce fetal death and a variety of fetal deformities. The present study considered the role of val pro ate as a behavioral teratogen in rats. Pregnant rats were administered saline or valproate, or simply handled at 10 days gestation and the offspring tested for a variety of behaviors and physical measures. Valproate-exposed animals demonstrated lags in the emergence of swimming behavior, negative geotaxis and weight gain. This evidence points to val pro ate being a behavioral teratogen producing delays in neuromuscular development.

Microhabitat Preferences Of Bullfrog Tadpoles (Rana Catesbeiana) Of Different Ages, Geoffrey R. Smith

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

I experimentally investigated the habitat use preferences of bullfrog (Rana catesbeiana) tadpoles of different ages (early, first-year vs. late, second-year, premetamorphic) in the laboratory. Early tadpoles showed a preference for non-vegetated areas, whereas late tadpoles showed no preference. Early tadpoles were seen more often over small, gravel substrate as opposed to large rocks, whereas late tadpoles showed no preference. Early tadpoles preferred medium depths, whereas later tadpoles preferred deeper water. Thus, it appears there may be habitat preferences in bullfrog tadpoles, and that these preferences may change over time.

Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert

Communication Skills Collection

Geographic variation in alarm calls of Gunnison's prairie dogs (Cynomys gunnisoni) was analyzed at regional and local scales. Alarm calls in response to a common stimulus (the same human) were recorded at four colonies near Flagstaff, Arizona, and at six sites throughout the southwestern United States. The acoustic structure of calls was analyzed for seven call variables. Regional differences fit the prediction of greater differences with increased geographical separation. Differences between colonies at a local scale were not related to geographical distance, suggesting that local dialects exist within a region. Differences in the level of predation by humans …

Apostatic Selection By Blue Jays Produces Balanced Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil

Papers in Behavior in Biological Sciences

Apostatic selection, in which predators overlook rare prey types while consuming an excess of abundant ones, has been assumed to contribute to the maintenance of prey polymorphisms. Such an effect requires predators to respond to changes in the relative abundance of prey, switching to alternatives when a focal prey type becomes less common. Apostatic selection has often been investigated using fixed relative proportions of prey, but its effects on predator–prey dynamics have been difficult to demonstrate. Here we report results from a new technique that incorporates computer-generated displays into an established experimental system, that of blue jays (Cyanocitta cristata …

Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor

Ethology Collection

1. Current game theory models and recent experimental evidence suggests that the strategy an animal adopts in agonistic encounters is determined by individual state. Therefore manipulation of an individual’s state should elicit different behavioural responses. In this paper, mechanisms are examined that underlie state-dependent strategies using Shore Crabs, Carcinus maenas, and how, by altering the environment, behaviour and physiology are affected.
2. Fights were staged between pairs of male crabs under normoxic and severely hypoxic (< 15 torr) conditions to determine if the metabolic costs of fighting and resource acquisition are affected by water P_O2. After fighting, blood and tissue samples from each crab were taken and analysed for metabolites associated with anaerobiosis (L-lactate, glucose and glycogen).
3. The spectrum …

Animal Organs In Humans: Uncalculated Risks And Unanswered Questions, Gillian R. Langley, Joyce D'Silva

Biomedicine and Animal Models in Research Collection

This report, produced jointly by the British Union for the Abolition of Vivisection and Compassion in World Farming, fills a number of significant gaps in the current debate about xenotransplantation.

In this report we also summarise the ethical and welfare issues concerning experiments on animals for xenotransplant research and their possible use as source animals for organs. Both these aspects are responsible for much pain and distress caused to many animals. We prefer the term “source animals” to “donor animals”, because animals do not choose to donate their organs for xenotransplantation.

The Relationship Between Physical Activity And Flexibility, Tanya Marie Schramm

Student Work

The purpose of this study was to determine if a relationship existed between flexibility and physical activity levels. Subjects included 128 male (n=64) and female (n=64) volunteers, 19 to 55 years of age. All subjects completed a physical activity questionnaire (which differentiated between work, sport, leisure and total physical activity) and a series of five flexibility tests. Four of the five flexibility tests were completed with the use of a goniometer which measured shoulder flexion, hip flexion, knee flexion and ankle dorsiflexion. The sit and reach test was used to assess hamstring­ lumbar flexibility. After analyzing the data by using …
