Abstract Nonnative plant invasions can have devastating effects on native communities; conversely, management efforts nontarget and deleterious impacts desirable plants. In the arid sagebrush steppe rangelands of western United States, nonnative winter annual species affect forage production biodiversity. One method proposed to control these is suppress soil seedbank using preemergent herbicide...

Metal contaminants in soil environments derived from industrial pollution have clearly established the need for research on bioavailability and potential health risks. Much research has been conducted on metal sorption in soils. However, there is still a need to better understand the availability of metal contaminants to plants and microbes. Such information will enhance both human health and d...

To assess the role of auxin flows in plant vascular patterning, the development of vascular systems under conditions of inhibited auxin transport was analyzed. In Arabidopsis, nearly identical responses evoked by three auxin transport inhibitor substances revealed an enormous plasticity of the vascular pattern and suggest an involvement of auxin flows in determining the sites of vascular differ...

Title of Thesis: EVALUATION OF CONSERVATION STRIPS AS A CONSERVATION BIOLOGICAL CONTROL TECHNIQUE ON GOLF COURSES Steven D. Frank, Master of Science, 2003 Thesis directed by: Assistant Professor Paula M. Shrewsbury Department of Entomology Conservation strips combine the conservation biological control tactics of beetle banks and flowering insectary strips. Conservation strips were established ...

A requirement for understanding morphogenesis is being able to quantify expansion at the cellular scale. Here, we present new software (RootflowRT) for measuring the expansion profile of a growing root at high spatial and temporal resolution. The software implements an image processing algorithm using a novel combination of optical flow methods for deformable motion. The algorithm operates on a...
