The effect of one-session exposure treatment on selective processing and explicit memory bias in snake- and spider-fearful participants

09 Apr 2013 | 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

09 Apr 2013 | 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 …

Role of near-miss bird strikes in assessing hazards

04 Apr 2013 | Journal Articles | Contributor(s): Matthew W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Begier

Management of problem wildlife within the airfield environment is a difficult job. Today’s Bird–Animal Aircraft Strike Hazard (BASH) program managers require as much information as possible to accomplish their tasks. Bird censuses and actual bird-strike events in and around the air operations …

Eastern bluebirds eject brown-headed cowbird eggs

04 Apr 2013 | Journal Articles | Contributor(s): Brian D . Peer, Lyndon R. Hawkins, Edwin P. Steinke, Patricia Blair Bollinger, Eric K. Bollinger

The relationship between the Brownheaded Cowbird (Molothrus ater) and its cavitynesting hosts has received little attention because of the assumption that cowbirds rarely parasitize these hosts. We tested the Eastern Bluebird (Sialia sialis), a host that is sometimes heavily parasitized by …

Predictive measures of fetal distress in calves during delivery

04 Apr 2013 | 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

04 Apr 2013 | 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 …

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 studies …

Badger movement ecology in Colorado agricultural areas after a fire

04 Apr 2013 | Conference Proceedings | Contributor(s): Craig Ramey, Jean Bourassa

While investigating the American badger (Taxidea taxus) in eastern Colorado’s wheatlands, we studied 3 badgers which were affected by a 2.1 km2 man-made fire and compared them to 2 adjacent badgers unaffected by the fire. All badgers were equipped with radio-telemetry collars and generally …

Evaluation of a new strategy for control of bovine tuberculosis in Michigan white-tailed deer: year 1 progress report

03 Apr 2013 | Conference Proceedings | Contributor(s): Stephen Schmitt, Daniel O\'Brien, Elaine Carlson, David Smith, Zachary Cooley

The State of Michigan is striving to eliminate bovine tuberculosis (Tb) infection among free-ranging white-tailed deer in the northeastern Lower Peninsula of the state. Aggressive reduction in the overall deer population abundance may help to further reduce TB prevalence, but this course of action …

Evaluation of moderate and low-powered lasers for dispersing double-crested cormorants from their night roosts

03 Apr 2013 | Conference Proceedings | Contributor(s): James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr

The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective strategy for alleviating cormorant depredations in areas of intensive catfish production is coordinated …

Effects of breed group by location interaction on crossbred cattle in Nebraska and Florida

03 Apr 2013 | Journal Articles | Contributor(s): T. A. Olson, K. Euclides Filho, L. V. Cundiff, M. Koger, W. T. Butts Jr.

Data on 2,744 calves produced in Clay Center, Nebraska, and Brooksville, Florida, were used to evaluate the importance of genotype × location interactions on the reproductive and maternal performance of eight breed groups of F1 crossbred cows. A total of 648 F1 crossbred cows included Bos taurus …

Abundance of bottlenose dolphins (Tursiops Truncatus) in the big bend of Florida, St. Vincent Sound to Alligator Harbor

03 Apr 2013 | Theses | Contributor(s): Reny Blue Tyson

Mark-recapture surveys implementing photographic identification techniques were used to estimate the abundance of bottlenose dolphins in an area of the Big Bend of Florida, stretching from St. Vincent Sound to Alligator Harbor, in the summer of 2007 and winter of 2008. The current population size …

Quantitative genetic analysis of reproduction traits in ball pythons

03 Apr 2013 | Theses | Contributor(s): Benson H. Morrill, Lee F. Rickords (adviser)

Although the captive reproduction of non-avian reptiles has increased steadily since the 1970’s, a dearth of information exists on successful management practices for large captive populations of these species. The data reported here come from a captive population of ball pythons (Python regius) …
