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...
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 skunk (Spilogale putorius...
Resource selection by black-footed ferrets in relation to the spatial distribution of prairie dogs
(University of Missouri--Columbia, 2007)
Once extinct in the wild, the black-footed ferret (Mustela nigripes) is one of the rarest mammals in North America. Reintroductions of ferrets at 13 sites over 10 years have resulted in only 3 self-sustaining populations. ...
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 ...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
I determined various factors affecting the resource selection and spatial ecology of the Indian fox Vulpes bengalensis, a small canid endemic to the Indian subcontinent. I collected radiotelemetry data from 32 Indian foxes ...
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...
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...
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...
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 ...
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), ...
Establishing mostly-male bluegill groups and evaluating their growth benefits in indoor rearing systems
(University of Missouri--Columbia, 2007)
Male bluegill have the greatest potential to reach food market size ([greater than or equal to] 0.5 lb.; 225g) within two growing seasons. However, establishment of monosex, juvenile bluegill groups does not currently ...
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...
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 ...
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...
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...
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...
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...
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 ...
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 ...
