Mating systems in Nicotiana longiflora and N. Plumbaginifolia : the effect of interspecific interactions
(University of Missouri--Columbia, 2008)
The research presented here was focused on the effects of interactions between Nicotiana longiflora and N. plumbaginifolia on their mating systems. First, I conducted a series of observations and pollination experiments ...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
their extensive native distribution. Much less is known about levels and distribution of diversity within the species. In 1940, Carl Hubbs and Reeve Bailey published descriptions of two distinct subspecies: the Northern Smallmouth Bass (M. d. dolomieu), inhabiting...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
determining microhabitat use. Further, I have demonstrated the effects of matrix composition on the frequency of inter-pond movements and elucidated historical patterns of gene flow across central Missouri. My data indicate that migration through terrestrial...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
populations in Missouri.The results of my dissertation research indicate that the quantity and quality of terrestrial habitat available to pond-breeding amphibians can have substantial population level consequences including increased extinction probabilities...
Plasticity of neurons in mouse major pelvic ganglia in response to loos of physiological input in cases of nerve injury and spinal cord injury
(University of Missouri--Columbia, 2018)
bladder, incontinence and inefficient voiding. While extensive SCI research has been done locomotor recovery, relatively limited amount of research has been done on the underlying mechanisms of autonomic dysfunctions associated with SCI. The major pelvic...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
Effective amphibian conservation requires an understanding of how populations respond to specific natural and anthropogenic factors. Chemical contaminants are among the known sources of acute and chronic stress and have ...
The impacts of partner abundance on benefits from facultative pollination mutualism
(University of Missouri--Columbia, 2010)
Partner abundance affects costs and benefits in obligate mutualisms, but its role in facultative partnerships is less clear. I investigated this topic in a small alpine pollination web in the Colorado Rocky Mountains ...
Weed versus wildflower : mating system ecology in a taraxacum native-exotic contact zone
(University of Missouri--Columbia, 2020)
Closely related plant species often exhibit differences in ploidy level, mode of reproduction, and traits related to reproduction. Differences in ploidy levels are often associated with mating system differentiation, ...
