Zinc phosphide rodenticide reduces cotton rat populations in Florida sugarcane

10 Apr 2013 | Conference Proceedings | Contributor(s): Nicholas R. Holler, David G. Decker

Rodents cause extensive damage to sugarcane (Saccharum spp. hybrids) in southern Florida (Samol 1972). Losses have been estimated as high as $235/ha (Lefebvre et al. 1978). Cotton rats (Sigmodon hispidus) and roof rats (Rattus rattus) are responsible for most of the damage (Holler et al. 1981). …

Impacts of house mouse activity on five types of insulation

10 Apr 2013 | Conference Proceedings | Contributor(s): Scott E. Hygnstrom

House mice (mus musculus) cause a variety of problems with livestock, feed, and structures. Researchers have yet to discover an insulative material that is not susceptible to house mouse damage. In this study, house mice caused significant (P < 0.01) increases in the thermal conductance of 10.2-cm …

Re-integrating crops and livestock in Maine: an economic analysis of the potential for and profitability of integrated agricultural production

09 Apr 2013 | 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

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 …
