Analysis of post-translational modifications of the blue light photoreceptor, phot1, by the CRL3NPH3 ubiquitin ligase complex
(University of Missouri--Columbia, 2013)Plants are sessile by nature; because of this they have evolved many strategies to cope with the diverse environmental stimuli they encounter in nature. One such strategy is the phototropic response by which plants reorient ... -
Complex life-histories and biogeochemical cycles : interactions between amphibian life-history strategies and elemental cycling
(University of Missouri--Columbia, 2013)All life must balance two key currencies: energy and matter. My dissertation focuses on the struggle that animals face in balancing various permutations of the latter currency: elements. The availability of essential ... -
Genetics and functional genomics of abscission
(University of Missouri--Columbia, 2013)Abscission is the shedding of plant organs as part of development or in response to environmental stresses. In the model plant Arabidopsis thaliana, only the floral organs abscise as part of development. This is controlled ... -
Hellbender (Cryptobranchus alleganiensis) gene flow within rivers of the Missouri Ozark highlands
(University of Missouri--Columbia, 2013)For species of conservation concern, effective management includes maintaining robust population sizes while monitoring and promoting genetic variability. For hellbenders (Cryptobranchus alleganiensis), an aquatic salamander ... -
Influence of habitat selection and habitat quality on the demography of a neotropical migrant songbird, the Bell's vireo (Vireo bellii)
(University of Missouri--Columbia, 2013)Individual fitness varies with the quality of the habitat occupied. Variation in habitat quality is difficult to assess, particularly in heterogeneous habitats where quality may differ within a single patch. Individuals ... -
Movement ecology of juvenile pond-breeding salamanders: implications for the management and conservation of amphibian populations
(University of Missouri--Columbia, 2013)Human-induced habitat change is widely regarded as a primary factor threatening the persistence of species. One major consequence of habitat alteration is its effect on the movement behavior of individuals. Spotted salamanders ... -
Sensory processing and the evolution of female preference in Neoconocephalus
(University of Missouri--Columbia, 2013)While the importance of the female preference for exaggerated male traits is largely understood, the evolutionary origins remain under debate. During the evolution of the female preference for leading signals via a sensory ...
