A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
's effects on sport fish populations have sparked controversy. The MDC responded by increasing efforts to monitor river otter populations, using latrine site counts to measure relative abundance across several rivers in Missouri. However, the actual number...
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 skunk (Spilogale putorius...
Experimentally assessing the influence of resource availability and social aggregation on the parasites of raccoons
(University of Missouri--Columbia, 2009)
I investigated how experimental increases in social aggregation and resource availability affected ectoparasite prevalence and intensity (number of parasites on infested hosts only) and endoparasite species richness of raccoons. Twelve independent...
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...
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...
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 ...
Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
Populations of many native big-river fishes have declined since channelization and flow regulation contributed to losses of shallow-water habitat (SWH) on lower Missouri River (LMOR). Existing point and wing-dike sandbars represent a potentially...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Response of raccoon spatial and social behavior to the presence of an experimentally clumped food resource
(University of Missouri--Columbia, 2009)
In order to examine the effect of clumped resource patches on the transition from a solitary to a social or group-living lifestyle in a putativeIy solitary carnivore I contrasted raccoons inhabiting two adjacent sites on the University of Missouri...
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 ...
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 was identified using a few...
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 ...
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 ...
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), ...
Hydrology, vegetation and waterbird response to land management strategies in the San Luis Valley
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The distribution of wetlands in the San Luis Valley has been altered by human modifications that influence the timing, distribution and characteristics of wetland environments...
Ecology of mid-continent migratory shorebirds, performance of tracking devices, and modelling animal social structure and demography
(University of Missouri--Columbia, 2022)
) developing and evaluating a modelling approach to combine social structure and survival information. In chapter 1, we found that winter and spring weather conditions influenced migration duration and number of stopovers in black-bellied plovers...
Decision-making and demography of greater white-fronted geese
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Greater white-fronted geese (Anser albifrons) are Arctic-nesting waterfowl with breeding ranges distributed throughout the Arctic. Due to this broad distribution...
