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 data within the context...
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
short-term ([greater than] 30 min) stressors in two animal models. Using a double-antibody radioimmunoassay, we quantified FGM levels after short-term stressors and compared them to plasma glucocorticoid levels in captive raised New Zealand White rabbits...
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 ...
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 ...
Space use and resource selection by Eastern spotted skunks in the Ouachita Mountains, Arkansas
(University of Missouri--Columbia, 2007)
Once a common and economically important furbearer, the eastern spotted skunk (Spilogale putorius) is now listed as endangered, threatened, or a species of conservation concern throughout much of its historical range. ...
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 ...
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 ...
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 ...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
Animal population dynamics are driven by variation in survival and productivity. Long-lived species such as Arctic-nesting geese often are characterized by high adult survival and low but highly variable annual reproductive success. Productivity...
Decision-making and demography of greater white-fronted geese
(University of Missouri--Columbia, 2019)
for researchers to obtain previously inaccessible information on animal movements, energy expenditure, and fine-scale behaviors, including estimation of time spent feeding. We used Bayesian generalized linear mixed models to quantify behavioral differences in four...
Habitat selection and movements of diploid and triploid grass carp in a large reservoir
(University of Missouri--Columbia, 2020)
Grass Carp, an herbivorous fish introduced in North America to control aquatic vegetation, has become an increasing ecological threat to aquatic ecosystems they invade. Grass Carp have the potential to cause declines and ...
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)
North American bat species face a range of environmental stressors which have negatively impacted recovery of the endangered Indiana bat (Myotis sodalis) and led to inclusion of the northern long-eared bat (Myotis ...
Habitat and landscape characteristics that influence population density and behavior of gray squirrels in urban area
(University of Missouri--Columbia, 2006)
Recent trends in ecological studies have displayed increases in the studying of urban systems and wildlife. Investigations on various urbanized taxa have often described similar behavioral (reduced fear of humans, altered ...
Ecology of mid-continent migratory shorebirds, performance of tracking devices, and modelling animal social structure and demography
(University of Missouri--Columbia, 2022)
in two parts: (a) we present current literature and techniques for studying animal social structure and demography, and (b) we developed a simulation study that evaluated performance of a model linking social network analysis and Cormack...
Conservation biogeography of lotic fishes in the Missouri and Colorado River basins
(University of Missouri--Columbia, 2019)
To improve our understanding of lotic fish ecology and improve conservation efforts, I 1) identified potentially ecologically important tributaries (PEITs) and evaluated their effects on fish assemble structure, 2) evaluated ...
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 ...
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 ...
The role of the giant Canada goose (Branta canadensis maxima) cecum in nutrition
(University of Missouri--Columbia, 2006)
Waterfowl are renowned for their ability to exploit a wide variety of food resources. They feed on fresh and marine water invertebrates, aquatic and terrestrial plants, and agricultural grains and crops. This nutritional ...
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 ...
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. ...
