Development and evaluation of a terrestrial animal-borne video system for ecological research
(University of Missouri--Columbia, 2008)
Ashland, Missouri. My research shows that our AVEDs are powerful new tools for ecological research that do not elevate stress levels of captive white-tailed deer and enable ecological research opportunities that traditional methods (e.g., radio telemetry...
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 sp.) nests. The objectives...
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...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
Golden-cheeked warbler nest success and nest predators in urban and rural landscapes
(University of Missouri--Columbia, 2007)
We studied nesting success of Golden-cheeked Warblers (Dendroica chrysoparia) from 2005-2006 in urban and rural landscapes in central Texas. We used an information-theoretic approach to evaluate models representing hypotheses ...
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 trapping and the predator...
Conservation of Sooty Terns on Wake Atoll complex
(University of Missouri--Columbia, 2011)
I undertook two projects aimed at improving conservation efforts for Sooty Terns (Onychoprion fuscata). First, I investigated patterns of Sooty Tern chick survival to identify when chicks are most vulnerable and to assess ...
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...
Disinfection by-product precursors and formation potentials of Missouri reservoirs
(University of Missouri--Columbia, 2006)
autochthonous DOC and our goal was to determine the relative influence of allochthonous and autochthonous inputs on the DBP precursor pool in Missouri. Samples were collected from 76 reservoirs spanning a 12 month period from January 2004 through December 2004...
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...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
(University of Missouri--Columbia, 2008)
I compared nest survival and breeding density between native bottomland forest and cottonwood (Populus deltoides) plantations over a three-year period for Acadian Flycatcher (Empidonax virescens), Prothonotary Warbler ...
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 ...
Habitat use and home range of American bitterns (Botuarus lentiginosus) and monitoring of inconspicuous marsh birds in northwest Minnesota
(University of Missouri--Columbia, 2007)
Information on habitat use of the American Bittern (Botaurus lentiginosus) and a statistically valid survey design for monitoring changes in populations of inconspicuous marsh birds, which include American and Least Bitterns ...
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 areas, urban wildlife has...
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...
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 ...
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 ...
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)
maternity habitat characteristics of the endangered Indiana bat (Myotis sodalis) in northern Missouri to identify factors that drive selection and 2) identify local- and landscape-scale habitat characteristics associated with occupancy of M. sodalis and M...
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. ...
