Maternity roost selection of Indiana bats (myotis sodalis) and occupancy of two threatened myotine bat species on national wildlife refuges in northern Missouri
(University of Missouri--Columbia, 2020)
maternity habitat characteristics of the endangered Indiana bat (Myotis sodalis) in northern Missouri to identify factors that drive selection and 2) identify local- and landscape-scale habitat characteristics associated with occupancy of M. sodalis and M...
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 ...
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...
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 ...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
.e. an aquatic-terrestrial zone (ATTZ), within the main channel of the lower Missouri River. Predictive models of sandbar morphometry (area, wetted perimeter, elevation, and water-surface slope) were developed to determine how changes in discharge affect...
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 Chariton Rivers...
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 assemblages as it related...
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.) and chub spp. (Macrhybopsis...
Enhancing bluegill production through least-cost diet development and novel rearing strategies
(University of Missouri--Columbia, 2010)
Amidst growing demand for large, food-size bluegill Lepomis macrochirus, lack of an affordable, balanced diet and inadequate rearing technologies remain the major concerns of bluegill producers seeking to run profitable ...
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 ...
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 ...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
An investigation of urban bat ecology in Baltimore, Maryland
(University of Missouri--Columbia, 2019)
In North America, bats are a taxon of concern that play an important role in insect control, and their response to urbanization varies. I wanted to discover if evaluating environmental and socioeconomic variables present ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
