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 ...
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 ...
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 ...
Integrated vegetation management recommendations for George Washington Carver National Monument
(University of Missouri--Columbia, 2011)
George Washington Carver National Monument (GWCA) is a 97 ha historic site in southwest Missouri. Park managers are responsible for management of more than 90 ha of grassland and woodland. There have been several efforts ...
Natal dispersal and survival of red-bellied woodpeckers in a fragmented landscape
(University of Missouri--Columbia, 2011)
Survival and dispersal during the juvenile life stage are critical to population connectivity and persistence, but the post-fledging period is the least studied stage of the avian life cycle. We intensively radio-tracked ...
Investigation of an invasive crayfish and its relation to two imperiled native crayfishes; anthropogenic influences, multi-scale habitat associations, and conservation options
(University of Missouri--Columbia, 2011)
The introduced Woodland Crayfish (Orconectes hylas) is spreading throughout the St. Francis River, Missouri. The imperiled Big Creek Crayfish (Orconectes peruncus) and St. Francis River Crayfish (Orconectes quadruncus) are ...
Factors affecting spatial and temporal dynamics of an ungulate assemblage in the Black Hills, South Dakota
(University of Missouri--Columbia, 2011)
Our goal was to gain empirical data on the spatial and temporal selection of resources by the ungulate assemblage in Custer State Park (CSP), South Dakota. To achieve this goal, we developed a spatially-explicit model to ...
Nest site selection in Arctic-breeding shorebirds: effects of habitat, social factors, and experience
(University of Missouri--Columbia, 2014)
Birds select nest sites based on factors that maximize their own survival and reproductive success. These factors include a location and structure that offers safety from predators, a favorable nest microclimate, proximity ...
Longitudinal Differences in Habitat Complexity and Fish Assemblage Structure of a Great Plains River
(American Midland Naturalist, 2010)
We investigated the spatial variation in the Kansas River (USA) fish assemblage to determine how fish community structure changes with habitat complexity in a large river.
Fishes were collected at ten sites throughout the ...
Effects of socioeconomics on European starling (Sturnus vulgaris) abundance in Baltimore, Maryland
(University of Missouri--Columbia, 2010)
This study predicted avian species using the social area analysis approach, and census tract block group variables. By using European Starlings (Sturnus vulgaris) as a focal species, I wished to determine what socioeconomic ...
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 ...
A study of the abundance, diversity, and recruitment status of freshwater mussels in the Marais des Cygnes River, Kansas
(University of Missouri--Columbia, 2009)
This study examines the status of a freshwater mussel assemblage located on the Marais des Cygnes River at the Marais des Cygnes National Wildlife Refuge in Kansas. Four mussel beds were selected and parameters including ...
Evaluation of patch-burn grazing on species richness and density of grassland birds
(University of Missouri--Columbia, 2009)
A patch-burn grazing (PBG) management technique was applied to four native tallgrass prairies in southwest Missouri to evaluate its effect on species richness and density of grassland birds. Treatment prairies were spring ...
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), ...
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 ...
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 ...
Pronghorn migration and resource selection in southwestern North Dakota
(University of Missouri--Columbia, 2009)
Wildlife managers need pronghorn (Antilocapra americana) movement data in North Dakota because harvest quotas are based on a summer survey, which might not represent the distribution of pronghorn during the fall hunting ...
In Ovo Exposure to o,p´-DDE Affects Sexual Development But Not Sexual Differentiation in Japanese Medaka (Oryzias latipes)
(National Institute of Environmental Health Sciences, 2003-01)
Despite being banned in many countries, dichlorodiphenyltrichloroethane (DDT) and its metabolites dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD) continue to be found in fish tissues at ...
