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 ...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
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 flexibility has allowed them...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
Disinfection by-product precursors and formation potentials of Missouri reservoirs
(University of Missouri--Columbia, 2006)
Dissolved organic carbon (DOC) in surface water affects the formation of halogenated disinfection by-products (DBP) in drinking water. Both the quality and quantity of DOC impact DBP formation. Allochthonous DOC is more ...
An evaluation of Missouri Master Naturalist Program: changes in volunteer knowledge and the relationship between motivations and changes in volunteer knowledge
(University of Missouri--Columbia, 2007)
The Missouri Master Naturalist (MN) program educates adults who then volunteer to help manage their community's natural resources. My research evaluated Missouri's MN training program. My first objective determined any ...
Macroinvertebrate and crayfish communities in the Meramec River drainage basin: an investigation at multiple spatial scales
(University of Missouri--Columbia, 2006)
Hierarchical classification systems have been widely used to delineate terrestrial ecounits at multiple spatial scales; however there has long been a need for an aquatic based classification system. A newly developed aquatic ...
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
Channel modification and flow regulation in historically braided large rivers, have reduced sandbars and associated highly productive habitats for riverine biota. Sandbars are an important interface between aquatic and ...
Nutrients and chlorophyll dynamics in Fort Cobb Reservoir
(University of Missouri--Columbia, 2007)
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 ...
