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 ...
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 ...
Golden-cheeked warbler nest success and nest predators in urban and rural landscapes
(University of Missouri--Columbia, 2007)
We studied nesting success of Golden-cheeked Warblers (Dendroica chrysoparia) from 2005-2006 in urban and rural landscapes in central Texas. We used an information-theoretic approach to evaluate models representing hypotheses ...
Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted ...
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, ...
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. ...
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 ...
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 ...
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 ...
Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
(University of Missouri--Columbia, 2013)
Many Missouri land management agencies are restoring savannas and woodlands using prescribed fire and forest thinning, and information is needed on how wildlife species respond to these management activities. Our objectives ...
Waterbird use and food availability on wetland reserve program easements enrolled in the migratory bird habitat initiative
(University of Missouri--Columbia, 2013)
The Natural Resource Conservation Service implemented the Migratory Bird Habitat Initiative (MBHI) in summer 2010 to mitigate potential loss of wetland habitat caused by the Deepwater Horizon oil spill. The goal of the ...
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 ...
Occupancy modeling of ruffed grouse in the Black Hills National Forest
(University of Missouri--Columbia, 2009)
Ruffed grouse (Bonasa umbellus) are important game birds and the management indicator species for quaking aspen (Populus tremuloides) in the Black Hills National Forest (BHNF). As a result, a robust monitoring protocol ...
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 ...
Evaluation and development of black-footed ferret resource selection models
(University of Missouri--Columbia, 2009)
Resource selection function (RSF) and utilization function (RUF) models aid in evaluating habitat suitability and investigating hypothesized mechanisms of space use of wildlife. We monitored postbreeding resource selection ...
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 ...
An evaluation of Missouri Master Naturalist Program: changes in volunteer knowledge and the relationship between motivations and changes in volunteer knowledge
(University of Missouri--Columbia, 2007)
The Missouri Master Naturalist (MN) program educates adults who then volunteer to help manage their community's natural resources. My research evaluated Missouri's MN training program. My first objective determined any ...
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 ...
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 ...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
Channel modification and flow regulation in historically braided large rivers, have reduced sandbars and associated highly productive habitats for riverine biota. Sandbars are an important interface between aquatic and ...
