Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

The impact of child-centered play therapy on anxiety levels in pre-neurosurgical pediatric patients

Creator:: Lerwick, Julie L.
Abstract:: The prevalence of childhood illness requiring hospitalization establishes the need for implementation of an applied intervention to decrease levels of hospitalization-induced anxiety in pediatric patients. In addition to anxiety, levels of perceived trauma have also been linked to pre-operative pediatric patients. Child-Centered Play Therapy (CCPT) within the medical setting has...

Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

Creator:: Peachey, Ronald Edward
Abstract:: This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

Geocaching: Perceptions of Impacts and Identity

Creator:: Fisher, Dianna M.
Abstract:: Geocaching is an outdoor recreational activity where participants (geocachers) utilize a handheld Global Positioning System (GPS) receiver or smartphone to download coordinates in order to navigate to the location of a hidden container, a geocache. Since its inception in 2000 geocaching has grown exponentially. The potential ecological and recreation management...

Vaccinia virus I7L core protein proteinase

Creator:: Byrd, Chelsea M.
Abstract:: Vaccinia virus (VV) is a large double-stranded DNA virus that is a prototypic member of the orthopoxvirus family. Previous works has showed that three of the major structural proteins found within the mature VV virion core 4a, 4b, and 25K are produced from higher molecular weight precursors at late times...

Developmental toxicity of polycyclic aromatic hydrocarbons : defining mechanisms with systems-based transcriptional profiling

Creator:: Goodale, Britton C.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment as components of fossil fuels and by-products of combustion. Defining toxicity mechanisms for this large family of multi-ring structures and substituted derivatives is a substantial challenge. Several PAHs, such as benzo(a)pyrene (BaP), are mutagenic, toxic to wildlife, and classified as probable...

Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:: Kimbrel, Jeffrey A.
Abstract:: Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...
