Hydrology, vegetation and waterbird response to land management strategies in the San Luis Valley
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The distribution of wetlands in the San Luis Valley has been altered by human modifications that influence the timing, distribution and characteristics ...
Habitat and landscape characteristics that influence population density and behavior of gray squirrels in urban area
(University of Missouri--Columbia, 2006)
Recent trends in ecological studies have displayed increases in the studying of urban systems and wildlife. Investigations on various urbanized taxa have often described similar behavioral (reduced fear of humans, altered ...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
Watershed-sediment-biotic linkages in small streams of Missouri's Osage River Basin
(University of Missouri--Columbia, 2009)
Sedimentation is an important variable influencing the complex physical and biological features of streams. Hierarchical models of watershed characteristics, within third-order streams of the Osage River Basin in Missouri, ...
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 ...
Response of raccoon spatial and social behavior to the presence of an experimentally clumped food resource
(University of Missouri--Columbia, 2009)
In order to examine the effect of clumped resource patches on the transition from a solitary to a social or group-living lifestyle in a putativeIy solitary carnivore I contrasted raccoons inhabiting two adjacent sites on ...
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.) ...
The role of the giant Canada goose (Branta canadensis maxima) cecum in nutrition
(University of Missouri--Columbia, 2006)
Waterfowl are renowned for their ability to exploit a wide variety of food resources. They feed on fresh and marine water invertebrates, aquatic and terrestrial plants, and agricultural grains and crops. This nutritional ...
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 ...
Effects of even-aged forest management on early successional bird species in Missouri Ozark forest
(University of Missouri--Columbia, 2005)
I examined the effect of different clearcut sizes on species richness, abundance, and reproductive success of five early successional birds: Yellow-breasted Chat (Icteria virens), Indigo Bunting (Passerina cyanea), White-eyed ...
A qualitative investigation of the urban minority adolescent experience with wildlife
(University of Missouri--Columbia, 2004)
An increase in urbanization has contributed to an increase in the general public's isolation from traditional uses of wildlife and led to changes in attitudes toward wildlife. Although the majority of people live in urban ...
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 ...
River restoration in the upper Mississippi River Basin
(University of Missouri--Columbia, 2006)
River restoration has become an important management choice to address causes and effects of surface water impairment and river modification in the Upper Mississippi River Basin (UMRB). I report information on individual ...
Disinfection by-product precursors and formation potentials of Missouri reservoirs
(University of Missouri--Columbia, 2006)
Dissolved organic carbon (DOC) in surface water affects the formation of halogenated disinfection by-products (DBP) in drinking water. Both the quality and quantity of DOC impact DBP formation. Allochthonous DOC is more ...
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ...
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 ...
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 ...
Butterfly gardening: using volunteers to provide data on flower use
(University of Missouri--Columbia, 2006)
Butterflies are considered to be good indicators of a healthy environment and reflect the environmental impact of urban development. The popularity of butterflies with the general public and declining butterfly populations, ...
Resource selection, movement patterns, and survival of post-fledging grassland birds in Missouri
(University of Missouri--Columbia, 2005)
Current grassland management paradigms focus on addressing nesting requirements for grassland birds, but ignore post-fledging requirements. I described resource selection, movement patterns, and survival of dickcissels ...
Habitat use and home range of American bitterns (Botuarus lentiginosus) and monitoring of inconspicuous marsh birds in northwest Minnesota
(University of Missouri--Columbia, 2007)
Information on habitat use of the American Bittern (Botaurus lentiginosus) and a statistically valid survey design for monitoring changes in populations of inconspicuous marsh birds, which include American and Least Bitterns ...
