Investigation of an invasive crayfish and its relation to two imperiled native crayfishes; anthropogenic influences, multi-scale habitat associations, and conservation options
(University of Missouri--Columbia, 2011)
, suggesting that it is not taking advantage of stressed aquatic environments to establish and replace native crayfishes. The most highly associated natural factors for all three species related to either soils or geology. Fine-scale habitat use of O. hylas...
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 ...
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 ...
Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
(University of Missouri--Columbia, 2013)
Many Missouri land management agencies are restoring savannas and woodlands using prescribed fire and forest thinning, and information is needed on how wildlife species respond to these management activities. Our objectives ...
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 ...
Evaluating sampling methods and investigating distribution and richness of fish and amphibians in Missouri wetlands
(University of Missouri--Columbia, 2017)
those already devastated. In Missouri, efforts to increase wetland area focused on establishing public wetland complexes where, in an attempt to restore ecological function, wetlands are actively managed with precise water level manipulation and soil...
Temporal patterns and variability of trophic state parameters in Missouri reservoirs
(University of Missouri--Columbia, 2010)
Eutrophic reservoirs in Missouri, as a group, do not display the bimodal spring and fall pattern of peak algal biomass that is accepted phenology in eutrophic temperate lakes. Instead, Missouri's eutrophic reservoirs display ...
Decision-making and demography of greater white-fronted geese
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Greater white-fronted geese (Anser albifrons) are Arctic-nesting waterfowl with breeding ranges distributed throughout the Arctic. Due to ...
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 ...
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 ...
Amphibians as wetland restoration indicators on Wetlands Reserve Program sites in Lower Grand River basin, Missouri
(University of Missouri--Columbia, 2010)
My research goal was to determine if hydrological and biological wetland characteristics had been restored to Wetlands Reserve Program (WRP) sites in the Lower Grand River basin, north-central Missouri, as indicated by ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
Freshwater mussels are among the most threatened aquatic fauna in North America. Given the need for continued monitoring of threatened mussel species, an evaluation of the effectiveness of metrics from visually-based ...
