Landscape and inchannel factors affecting the distribution and abundance of riverine smallmouth bass in Missouri
(University of Missouri--Columbia, 2008)
I developed a series of spatially-nested research objectives to identify habitat elements related to the distribution and abundance of riverine smallmouth bass Micropterus dolomieu in Missouri. The range of smallmouth bass was identified using a few...
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 UMRB river restoration...
Development and evaluation of a technique for evaluating riparian vegetation change in the tallgrass prairie
(University of Missouri--Columbia, 2004)
occurred before the onset of modern ecological inventories. As a result, managers, planners, and policy makers often make decisions that impact riparian vegetation without sufficient information regarding presettlement vegetation. To provide data that can...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
to highway construction activity adjacent to an Ozark stream in southwest Missouri. The most notable effect of road construction on the sediment dynamics in the Brush Creek watershed was the overall change in suspended sediment concentration which was 53...
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 improvement in volunteers...
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 ...
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 of wetland environments...
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 ...
Evaluating sampling methods and investigating distribution and richness of fish and amphibians in Missouri wetlands
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Freshwater wetlands are some of the most imperiled ecosystems on the planet, meaning species that depend on them are at great risk. In Missouri, wetland filling and drainage...
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 trapping and the predator...
Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
Populations of many native big-river fishes have declined since channelization and flow regulation contributed to losses of shallow-water habitat (SWH) on lower Missouri River (LMOR). Existing point and wing-dike sandbars represent a potentially...
Roost site selection by Indiana bats (Myotis sodalis) and comparison of foraging habitat selection by morphologically similar bat species in bottomland hardwood ecosystems
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] While bottomland hardwoods used to encompass a large portion of the south-central United States, due to clear cutting for agriculture and other purposes, the amount...
