Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
in the annual cycle. Additionally, effects of weather and climate on population viability will be important considerations as Missouri experiences warmer temperatures and potentially extreme changes in precipitation patterns. Finally, this study generated...
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...
Visit motivations and perceived benefits of farms, private forests and state/national parks in Missouri
(University of Missouri--Columbia, 2011)
This study explored the variability in visit motivations and perceived benefits of Missouri households from three natural settings: (1) Farms; (2) Private Forests; and (3) State/National Parks. Specific goals of this study were: (1) To describe...
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
Plateau of south-central Missouri, and Bear Cave Hollow (BCH), one of TCC's surface drainage streams, bed load entrainment and transport dynamics of mainly siliciclastic material, was evaluated using hydrological measurements and 670 painted tracer...
Conservation and ecology of breeding landbirds in a riparian restoration context
(University of Missouri--Columbia, 2006)
of floodplain forest restoration on a large, regulated river in an agricultural valley. I used infrared, time-lapse video to identify agriculture-associated nest predators as a primary source of nest mortality in the Sacramento River Valley, California. Then...
Rivers running through : an urban environmental history of the Kansas Cities and the Missouri River
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An environmental history of Kansas City and an urban history of the Missouri River, this dissertation shows how interconnected the city and the river were through the twentieth...
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)
A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized that these diets would...

(University of Missouri--Kansas City, 2012-06-13)
Thomas Jefferson has long been admired for his influence in many arenas in the colonial era of American history; however, his collection of writings has not been closely scrutinized for his geographic thought. This thesis ...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...

Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
