In this dissertation I used the hybridizing species complex of cattails (Typha spp., Typhaceae) to explore some of the processes that could contribute to hybridization rates. Cattails in northeastern North America comprise the native T. latifolia, the non-native… more Full Text: HYBRIDIZATION DYNAMICS IN CATTAILS (TYPHA SPP.,) IN NORTHEASTERN NORTH AMERICA: NICHE SEGREGATION, POLLEN DISPERSAL, MATING PATTERNS, AND THE IMPORTANCE OF LOCALSCALE PROCESSES A dissertation submitted to the Committee on Graduate Studies in partial …

Abstract: <p>Competition is known to impact population dynamics through both indirect and direct interactions, and direct interactions can often lead to injury in one or both parties. As such, response to injury through tissue regeneration can be important for surviving post-competitive interaction. However, the impacts of outside factors like temperature and genome size (e.g. polyploidy) are not… more Full Text: How Abiotic and Biotic Factors Can Alter the Competitive Landscape in an Aggressive Species Complex (Genus: Ambystoma) A thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirement for the Degree of Master of Science in …
