Remediating effects of human threats on lotic fish assemblages within the Missouri River basin : how effective are conservation practices
(University of Missouri--Columbia, 2012)
To develop tools that can improve agricultural conservation, I: 1) assessed total watershed condition and where agricultural conservation practices (CPs) are likely to be effective (hereafter primary management capacity) of stream segments...
Rural land uses of Scott County, Missouri : landowner decisions and bird communities
(University of Missouri--Columbia, 2016)
modifications that may be conducted due to climate change of rural southeast Missouri. Specifically, how do these compare and what vegetation characteristics predict the bird communities across three common land uses: agricultural fields, grassland habitat...
Survival, habitat use, and movement of resident and translocated greater prairie-chickens
(University of Missouri--Columbia, 2012)
-chickens than in residents, and in agricultural and private grassland habitats than in core protected prairie habitats. Habitat use did not differ between resident and translocated birds and a ranking of habitat preference indicated that birds preferred prairie...
Resource selection and space use of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri)
(University of Missouri--Columbia, 2010)
I investigated the ecological requirements of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri), with the intent to provide management recommendations that could help prevent its extinction. The species ...
Evaluating the relationship between local food availability and wetland landscape structure in determining dabbling duck habitat use during spring migration
(University of Missouri--Columbia, 2017)
Wetlands in the Nebraska's Rainwater Basin (RWB) have decreased by 90 percent over the past two centuries and are subject to on-going degradation of quality from urban and agricultural land-use practices. Losses in wetland habitat quantity...
Habitat and management effects on foraging activity of Indiana bats (Myotis sodalis) in northern Missouri
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The federally endangered Indiana bat (Myotis sodalis) uses fragmented forests in largely agricultural landscapes during the maternity season. Understanding how land use and land...
Spatial Analysis of Organic Carbon and Nitrogen Sedimentation in Four Northern Missouri Reservoirs: Implications for Optimal Sampling
(University of Missouri--Columbia, 2011)
Recent research suggests that the rate of sediment carbon storage of small agricultural impoundments alone may be of the same order-of-magnitude as that of the world's oceans. This estimate, and the fact that reservoirs continue to steadily increase...
Streams in a changing landscape : identifying candidate reference reaches to assess the physical and biotic integrity of Missouri's wadeable streams
(University of Missouri--Columbia, 2016)
.g., watershed drainage area, reach gradient, spring density), we used boosted regression trees to model the influence of channel morphology, substrate, cover, and water quality, and watershed-level flow modification and fragmentation, urbanization, agriculture...
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...
Evaluating sampling methods and investigating distribution and richness of fish and amphibians in Missouri wetlands
(University of Missouri--Columbia, 2017)
for agriculture and the elimination and degradation of floodplain wetlands due to river management projects account for the destruction of greater than 85 percent of the state's wetland area since the 1780's. River management projects, including damming...
Avian population responses to Anthropogenic landscape changes in Pohnpei, Federated Sates of Micronesia
(University of Missouri--Columbia, 2014)
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 ...
Temporal patterns and variability of trophic state parameters in Missouri reservoirs
(University of Missouri--Columbia, 2010)
Eutrophic reservoirs in Missouri, as a group, do not display the bimodal spring and fall pattern of peak algal biomass that is accepted phenology in eutrophic temperate lakes. Instead, Missouri's eutrophic reservoirs display ...
Movement, habitat use, and spawning characteristics of flathead and blue catfish on the lower Missouri River and tributaries
(University of Missouri--Columbia, 2010)
The movement and habitat use patterns of adult flathead and blue catfish were studied via acoustic and radio telemetry in the lower Missouri River and adjacent tributaries including the Grand, Lamine, Chariton, and Little ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
