The majority of studies in invasion ecology have focused on the individual in its new habitat or attributes of habitats that are invaded. There is a need for studies that explore the biology of species in native and introduced ranges. The goal of my thesis is to determine if an invasive plant has had a shift in life history traits after introduction. The study species was Silene latifolia. Also, when organisms leaves their native range, they also escape their natural enemies. The escape-from-enemies hypothesis theorizes that plants which escape natural enemies will shift more energy to growth and reproduction. Introduced plants should exhibit increased competitive ability compared to native plants. I will determine if introduced plants show increased competitive ability compared to natives.
