Novel Mass Spectrometric and Sampling Strategies for Investigating Neuropeptide Processing and Distribution
… genetic variations. In some instances, however, alternative sampling approaches such as microseparation with MALDI MS detection are necessary to pre-concentrate and partially purify neuropeptides and to reduce ionization suppression effects. Here we describe the use of capillary electrophoresis …

Validation of N-STaR Nitrogen Rate Recommendations and Evaluation of N-STaR Soil Sampling Procedures for Clay Soils in Arkansas
… The second objective was to examine potential sampling tools for their accuracy in collecting N-STaR soil samples while having the greatest ease-of-use. Alkaline hydrolyzable-N (AH-N) from soil samples collected by the N-STaR bucket and drill (BD), Kleen Hole Spade dry (KHS-D), Kleen Hole Spade …

Opportunistic Sampling by Level-Crossing
This dissertation addresses an alternative sampling method called level-crossing (LC). In recent years LC has emerged as an alternative to the traditional Nyquist-Shannon based sampling. While the conventional approach is an ideal enabler of reliable and perfect signal reconstruction, it is not …

Seaglider observations of biogeochemical variability in the Iberian upwelling system.
… observations. This thesis demonstrates an alternative sampling technique, providing high spatial and temporal resolution biogeochemical data through the use of an autonomous underwater gliderthe Seaglider. SG510 “Orca” was outfitted with sensors to measure dissolved oxygen, temperature, …

Environmental Factors Affecting the Landscape-Scale Spatio-Temporal Distribution of Small Mammal Assemblages Across the Northern Great Plains of North America
The logistic constraints of traditional sampling methods have limited our understanding of the effects of landscape-scale factors on the spatiotemporal distributions of rodents and shrews (small mammals), particularly in heterogeneous landscapes. I used owl pellets as an alternative sampling …

Management of the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in Iowa
… in Iowa. Secondary goals included; verifying an alternative sampling techniques for estimating A. glycines populations, evaluating the effect of planting date on A. glycines population growth, and investigating the potential of managing both C. trifurcata and A. glycines with a single insecticide …

Determination of a novel mine tracer gas and development of a methodology for sampling and analysis of multiple mine tracer gases for characterization of ventilation systems
… largely dependent on the accuracy of release and sampling methods. Therefore, an analysis of sampling methods is crucial for rapid response and dependable results during emergencies. This research project involves evaluating and comparing four well-accepted sampling techniques currently utilized …

Development of monitoring methods for crayfish populations
Standardized sampling methods for assessing the community structure and health of stream fisheries, freshwater mussels, and insects have been used for several decades. However, such methods are woefully lacking for crayfish. The research of this project involved evaluation of several methods for …
