(Socio-)ecological tools and insights for a changing climate
(University of Missouri--Columbia, 2022)
to advance climate action in Missouri, I investigate how state-level decision-makers and land-use experts are thinking about climate resilience in the context of rural Missouri. More specifically, in chapter one, I explore how the use of lethal sampling, a...
The Production of Space, Place, and Food: The Ecology of Money and the Emergence of Transformative Circuits of Money Capital
(2015-08-04)
This dissertation argues that Henri Lefebvre’s (1991) The Production of Space
expresses a theoretical blueprint for the construction of an interdisciplinary approach to
social science that integrates political economy, ...
Greenhouse gas emissions and soil microbial activity for selected land use systems in floodplains
(University of Missouri--Columbia, 2022)
and droughts (IPCC, 2021). An estimated 23 percent of total anthropogenic greenhouse gas emissions (2007-2016) derive from agriculture, forestry, and other types of land use. Land management activities affect the soil microbiome and thus greenhouse gas (GHG...
Cross-cutting knowledge organizations as leverages of entrepreneurial activity
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Motivated by the possibility of obtaining relational rents (Dyer & Singh, 1998; Lavie, 2006), firms have used inter-firm networks as knowledge leverages. But which type of ties...
First quantitative trait loci detected for bearing habit and nut quality traits in eastern black walnut (Juglans nigra L.)
(University of Missouri--Columbia, 2022)
. First, literature is reviewed related to the initial selection efforts and foundation of the eastern black walnut breeding program at the University of Missouri Center for Agroforestry, while also examining advances in genetics, metabolomics...
Understanding rural poverty clusters : the intersection of agriculture, economic structure and locality under postindustrialism
(University of Missouri--Columbia, 2006)
Analysis seeks to understand rural poverty within the context of agricultural and postindustrial economic structure. Detailed socioeconomic data are analyzed for 4,610 non-metropolitan census tracts in the north central United States. Statistical...
Evaluating organizational research climate to assess research integrity
(University of Missouri--Columbia, 2022)
of this dissertation study was to quantify differences in perceived climate between academic units to measure heterogeneity or homogeneity of research integrity across subunits in a multi university academic system, including a healthcare system. Second, to determine...
Streambank erosion and risk assessment of contaminant transport in Missouri watersheds
(University of Missouri--Columbia, 2010)
Sedimentation and herbicide are significant water quality concerns in claypan watersheds. Two separate watershed-scale studies were conducted in the Central Claypan Region of northeastern Missouri. One project investigated the effects of season...
A GIS protocol for enhancing the selection of agricultural runoff sampling locations and predicting the locations of potential pollutant transport in the upland environment
(University of Missouri--Columbia, 2022)
employed by the protocol allow for its use in various geographic regions. The methodology has been performed on sites in Linn County and Boone County, Missouri, and produces results consistent with those expected from other widely accepted methods...
Signals, cues, and information use in foraging decisions of herbivorous insects and a leaf-folding plant
(University of Missouri--Columbia, 2023)
in ecology and life history. I also studied the cues produced when leaves of sensitive plants temporarily stop foraging for light. In treehoppers, I hypothesized that recruitment signals would guide the choice of feeding sites by group-living immatures. Both...
