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 …

Invasive Phragmites is considered a potential threat to several species-at-risk (SAR), including some turtle… more Full Text: EFFECTS OF INVASIVE WETLAND MACROPHYTES ON HABITAT SELECTION BY TURTLES A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Sciences TRENT …
