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 ...
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...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
Occupancy modeling of ruffed grouse in the Black Hills National Forest
(University of Missouri--Columbia, 2009)
site, each season (i.e., year). Using this design, we estimated the necessary number of sites and repeat surveys at each site to achieve occupancy estimates which met precision requirements. Site requirements were high due to low ruffed grouse occupancy...
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 ...
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...
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 ...
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 ...
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...
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...
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), ...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
throughout the annual cycle influenced Atlantic brant productivity over the past 44 years using generalized linear mixed models. I modeled the effects of the North Atlantic Oscillation Index, temperature and precipitation, and regional snow and ice cover...
