Development and evaluation of a technique for evaluating riparian vegetation change in the tallgrass prairie
(University of Missouri--Columbia, 2004)
North America's tallgrass prairie region is one of the world's most endangered ecosystems. Recent management and research efforts have focused on the effects of anthropogenic change to upland components of the tallgrass prairie, however, little...
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 ...
Amphibians as wetland restoration indicators on Wetlands Reserve Program sites in Lower Grand River basin, Missouri
(University of Missouri--Columbia, 2010)
My research goal was to determine if hydrological and biological wetland characteristics had been restored to Wetlands Reserve Program (WRP) sites in the Lower Grand River basin, north-central Missouri, as indicated by distribution, recruitment...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
I determined various factors affecting the resource selection and spatial ecology of the Indian fox Vulpes bengalensis, a small canid endemic to the Indian subcontinent. I collected radiotelemetry data from 32 Indian foxes ...
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
Extirpated from Missouri by the 1930s, river otters (Lontra canadensis) were reintroduced by the Missouri Department of Conservation (MDC) from 1982-1992. Since the reintroductions, concerns over the legitimacy of otter ...
Maternity roost selection of Indiana bats (myotis sodalis) and occupancy of two threatened myotine bat species on national wildlife refuges in northern Missouri
(University of Missouri--Columbia, 2020)
North American bat species face a range of environmental stressors which have negatively impacted recovery of the endangered Indiana bat (Myotis sodalis) and led to inclusion of the northern long-eared bat (Myotis septentrionalis) as a federally...
Evaluating sampling methods and investigating distribution and richness of fish and amphibians in Missouri wetlands
(University of Missouri--Columbia, 2017)
those already devastated. In Missouri, efforts to increase wetland area focused on establishing public wetland complexes where, in an attempt to restore ecological function, wetlands are actively managed with precise water level manipulation and soil...
Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
between July and October, 2005. A suite of associated environmental factors were also measured. Habitat use and assemblage structure relative to three spatial (sandbar type, region within sandbars, and distance from shoreline within region) and two...
Influence of streambed substrate type and watershed properties on seston algal abundance
(University of Missouri--Columbia, 2008)
in the water column has resulted in the absence of shrimp and fish within the effected region. The dead zone has been linked to increased nitrogen concentrations in the Mississippi River as a result of fertilizer application in the Midwest...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
Savanna and woodland habitats were historically prevalent in the midwestern United States, and efforts to restore these communities are growing. Better knowledge of the responses of breeding and non-breeding birds to ...
Macroinvertebrate and crayfish communities in the Meramec River drainage basin: an investigation at multiple spatial scales
(University of Missouri--Columbia, 2006)
Hierarchical classification systems have been widely used to delineate terrestrial ecounits at multiple spatial scales; however there has long been a need for an aquatic based classification system. A newly developed aquatic ...
Conservation biogeography of lotic fishes in the Missouri and Colorado River basins
(University of Missouri--Columbia, 2019)
To improve our understanding of lotic fish ecology and improve conservation efforts, I 1) identified potentially ecologically important tributaries (PEITs) and evaluated their effects on fish assemble structure, 2) evaluated ...
Space use and resource selection by Eastern spotted skunks in the Ouachita Mountains, Arkansas
(University of Missouri--Columbia, 2007)
Once a common and economically important furbearer, the eastern spotted skunk (Spilogale putorius) is now listed as endangered, threatened, or a species of conservation concern throughout much of its historical range. ...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
(University of Missouri--Columbia, 2008)
I compared nest survival and breeding density between native bottomland forest and cottonwood (Populus deltoides) plantations over a three-year period for Acadian Flycatcher (Empidonax virescens), Prothonotary Warbler ...
Habitat selection and movements of diploid and triploid grass carp in a large reservoir
(University of Missouri--Columbia, 2020)
Grass Carp, an herbivorous fish introduced in North America to control aquatic vegetation, has become an increasing ecological threat to aquatic ecosystems they invade. Grass Carp have the potential to cause declines and alterations in aquatic...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), chlorophyll (Chl), fecal...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
I developed a series of research objectives organized in a spatial hierarchy to characterize larval fish nursery habitat within the lower Missouri River. Native carpsucker spp./buffalo spp. (Carpiodes spp./Ictiobus spp.) ...
Distribution and abundance of anurans in southeast Missouri
(University of Missouri--Columbia, 2005)
Studies were conducted on 15 1034 ha landscape blocks to investigate the effects of forest fragmentation and habitat availability on anuran populations. Detections of anurans did not indicate a correlation between the ...
Roadway effects on the hydrologic regime of temporary wetlands in the Missouri River floodplain in Missouri
(University of Missouri--Columbia, 2005)
The effects of roadways on wetland ecosystems are not clearly understood, although alterations of wetland hydrologic regimes have been frequently observed (Nunnery and Richardson 1997). The goal of this research was to ...
