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...
Roadway effects on the hydrologic regime of temporary wetlands in the Missouri River floodplain in Missouri
(University of Missouri--Columbia, 2005)
on the hydrologic regime of temporary wetland basins within the agricultural landscape of the Missouri River floodplain from Hartsburg to Independence, Missouri. This study is part of a larger existing research project designed by the Missouri Department...
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...
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 ...
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...
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 ...
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 ...
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...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
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...
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 flexibility has allowed them...
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 ...
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 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 ...
