A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
in differential correction has previously proven unreliable. The effectiveness of base data acquired through use of a second field unit as an on-site base station was compared with the use of CORS. The accuracy of data differentially corrected using base data...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
Disturbance-mediated oak (Quercus spp.) woodlands were formerly a prevalent community type in Missouri, and their restoration is a key objective of land management agencies and conservation organizations. Over one-third of wooded land in Missouri (2...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
Assessment of a voluntary nonlead ammunition outreach program on midwestern national wildlife refuges
(University of Missouri--Columbia, 2020)
at four managed hunts, 29 semi-structured interviews of program staff, and an online survey of 325 NWR staff. Objectives were to (1) examine lead exposure risks and suggest communication strategies, (2) explore attitudes and experiences of NWR staff...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, existing research has...
Understanding students' technology appropriation and learning perceptions in online learning environments
(University of Missouri--Columbia, 2005)
Distance education has the unique characteristic of using technologies as the primary means of delivery of instruction and interaction. The present study contributes to research dedicated to explaining or predicting phenomena related to distance...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish assemblages as it related...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
for greatest understanding of population level processes and to inform prioritization of conservation efforts for Atlantic brant. Future brant research should focus on nutrient dynamics of James Bay staging areas, identifying core breeding areas and quantifying...
The influence of climate and population structure on East Asian skeletal morphological variation
(University of Missouri--Columbia, 2022)
selection pressure of climate for different regions of the skeleton and between the sexes underscores the necessity of future ecogeographic research to holistically evaluate body form and to look for sex-specific patterns to better represent population...
Evolution of the Bahamian coastal environment of San Salvador Island over the last 3,500 years based on triangle pond sediment cores
(2014-07-25)
The multiproxy examination of ten soft sediment cores extracted from Triangle Pond
was used in order to establish alterations in the northwestern coastal environment of San
Salvador Island, The Bahamas over the last 3,500 ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
