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 ...
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ...
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 ...
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 ...
Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted ...
Incidental take and endangered species demography
(University of Missouri--Columbia, 2008)
Incidental take is the permitted killing, harming, harassing or destroying habitat of an endangered species under endangered species law. Legislation assumes that endangered or threatened populations can somehow compensate ...
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 ...
Effects of temperature, photoperiod, and substrate on the maturation and reproductive behavior of the Topeka shiner (Notropis topeka)
(University of Missouri--Columbia, 2008)
The Topeka shiner (Notropis topeka) is a federally-listed endangered cyprinid species native to small headwater prairie streams in the mid-west of the United States. It generally spawns over and around sunfish (Lepomis ...
Development and evaluation of a terrestrial animal-borne video system for ecological research
(University of Missouri--Columbia, 2008)
Animal-borne video and environmental data collection systems (AVEDs) are integrated sensor systems that combine video from the animal's perspective with data from other sensors (e.g., audio, location). By placing sensor ...
Persistent organic pollutant effects on middle Mississippi River Scaphirhynchus sturgeon reproduction and early life stages
(University of Missouri--Columbia, 2011)
Pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (Scaphirhynchus platorynchus) populations have been in decline over the past century and contaminants may be a contributing factor. Two studies were designed ...
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 ...
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 ...
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 ...
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 ...
An assessment of stream fish vulnerability and an evaluation of conservation networks in Missouri
(University of Missouri--Columbia, 2014)
Stream fish species in Missouri are being exposed to habitat degradation, as well as increases in stream temperature and alterations to the flow regime due to climate change. These threats are likely to have negative ...
Greater sage-grouse nest site selection, brood-rearing site selection, and chick survival in Wyoming
(University of Missouri--Columbia, 2014)
Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) populations throughout North America were recently listed as �warranted but precluded� under the Endangered Species Act. North America�s largest wind ...
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) ...
A qualitative investigation of the urban minority adolescent experience with wildlife
(University of Missouri--Columbia, 2004)
An increase in urbanization has contributed to an increase in the general public's isolation from traditional uses of wildlife and led to changes in attitudes toward wildlife. Although the majority of people live in urban ...
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 ...
