Inbreeding Depression in the Partially Selfing Perennial, Ruellia Humilis
Ruellia humilis is a long-lived perennial herb found commonly in dry prairies and glades within the highly fragmented tallgrass prairie ecosystem. This species is characterized by showy chasmogamous flowers that promote outcrossing via hawkmoths and automatically self-fertilizing cleistogamous …

Causes and consequences of prolonged dormancy: Why stay belowground?
<p>Prolonged dormancy is a stage in which mature plants fail to resprout during the growing season and instead remain alive belowground. Though it is relatively common, the causes and consequences of this intriguing stage have remained elusive. In this dissertation, I investigate the causes and …

Transient dynamics in plant population models
… transient dynamics in plant populations based on long-term demographic data. Based on a survey of modeling results for plant populations in the literature, I found that theoretical indices of transient behavior greatly overemphasized the role of transient responses for the populations for which …

Characterizing phenotypic diversity, genotype by environment interactions, and optimizing selection efficiency of a miscanthus germplasm collection
… thus reducing the time between selections. For a long-lived perennial grass such as Miscanthus, minimizing the number of years per selection cycle will be critical for maximizing genetic gain per unit time. Genetic variation for cold tolerance in Miscanthus can be used to optimize planting dates …
