Land cover changes (1815 to 2007) in the central Missouri River Hills
(University of Missouri--Columbia, 2009)
predominantly forested central Missouri River Hills, this study assesses the magnitude of land cover change between four dates: the onset of European American settlement (circa 1815), near the period of maximum agricultural land use (1939), and through recent...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
, Missouri, and South Carolina are determining the effects of timber harvest on the persistence of amphibian populations. The purpose of my dissertation research was to define adult wood frog nonbreeding habitat in continuous oak-hickory forest...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading variability in Missouri Ozark...
Perceptions of rangeland degradation and its causes in the Peruvian Altiplano dry puna
(University of Missouri--Columbia, 2019)
. Perceptions of the causes of rangeland degradation were also different. While stakeholders believed that the major cause of degradation was overgrazing through overstocking and inappropriate management, pastoralists believed that the major cause was climate...
Evaluating and improving the performance of radar to estimate rainfall
(University of Missouri--Columbia, 2008)
A network of 10 rain gages reports data from the Goodwater Creek catchment in central Missouri. Because such a network is expensive to operate, it could be useful instead to use only a few gages and augment the observations with radar...
Geochemical and mineralogical analysis of pre-Columbian stone tools from La Piedra Pintada, Baja California Sur, Mexico
(University of Missouri--Kansas City, 2012-01-10)
Piedra Pintada is located in San Pablo Canyon, one of a series of major canyons that bisect the mountainous interior of the southern Baja California Peninsula, Mexico. Among the resources used by the canyon's prehistoric ...
Forage production and diversification for climate-smart tropical and temperate silvopastures
(University of Missouri--Columbia, 2019)
Climate change creates much uncertainty for the future of animal agriculture, particularly due to an increase in summer droughts that result in the loss of range productivity. Silvopasture, the intentional integration of livestock, trees...
The Bavarian model? : modernization, environment, and landscape planning in the Bavarian nuclear power industry, 1950-1980
(University of Missouri--Columbia, 2009)
Perhaps no state in the Federal Republic of Germany witnessed a more pronounced state sponsored modernization effort than Bavaria, 1950-1980. This vast transformation, particularly in the field of nuclear energy, required ...
Spatial distribution and historical dynamics of threatened conifers of the Dalat Plateau, Vietnam
(University of Missouri--Columbia, 2011)
general land cover types in the study area, these conifer species occurred in the mixed forest and the coniferous forests, from 1,000 - 2,200 m asl. Results show that the stand structures for these conifer species were unimodal and decreasing. Age...
Traditional postpartum care : alloparenting from an evolutionary perspective
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation focuses on traditional postpartum care and its variation across different human populations using an evolutionary framework. Whereas traditional healthcare may...
Resource selection and space use of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri)
(University of Missouri--Columbia, 2010)
I investigated the ecological requirements of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri), with the intent to provide management recommendations that could help prevent its extinction. The species ...
Middle and late woodland period cultural transmission, residential mobility, and aggregation in the deep South
(University of Missouri--Columbia, 2009)
This research attempts to reconstruct the extent of prehistoric human interaction within the lower Chattahoochee-Apalachicola River valley and neighboring Gulf Coast for the period spanning 200 B.C. to A.D. 1000. Using ...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
The study of coprolites and their internal constituents has previously employed a predominantly destructive means of extraction, resulting in the partial or complete loss of the specimen. Recently, however, there have been ...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
and conservation of the species using a combination of morphological, genetic, and genomic data: 1) patterns of genetic and morphological differentiation between the Neosho and Northern Smallmouth Bass subspecies, 2) lineage diversification and the extent...
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)
