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...
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...
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 ...
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 ...
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 ...
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...
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 ...
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 ...
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 ...
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 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 ...
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...
Spatiotemporal variation in Lake Sturgeon movement and habitat selection in Missouri river tributaries : implications for the management and recovery of populations at range margins
(University of Missouri--Columbia, 2021)
Lake Sturgeon were nearly extirpated from Missouri by the 1970s leading the Missouri Department of Conservation (MDC) to list the species as endangered within the state. Recovery efforts commenced with the publication of the first edition...
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...
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 ...
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 ...
Spatial and disease ecology of the plains spotted skunk
(University of Missouri--Columbia, 2019)
The eastern spotted skunk (Spilogale putorius) is a species of conservation concern across much of its range in the eastern U.S. due to a range-wide population decline that began in the 1940s. The reason for the decline ...
Ecology of mid-continent migratory shorebirds, performance of tracking devices, and modelling animal social structure and demography
(University of Missouri--Columbia, 2022)
Migratory birds are threatened by landscape and climate change, and shorebirds are particularly imperiled. Shorebirds undertake some of the most impressive migrations in the world, but in every season, there are threats ...
Resource selection, movement patterns, and survival of post-fledging grassland birds in Missouri
(University of Missouri--Columbia, 2005)
meadowlarks (Sturnella magna) in southwestern Missouri, from 2002 to 2004 using radio telemetry. Across species at the micro-scale, there was support for the predation hypothesis (both species) and the thermal refuge hypothesis (dickcissels only). Woody cover...
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...
