Genetic Diversity In Native And Invasive Rubus (Rosaceae), Ashley A. Wint Aug 2008

Genetic Diversity In Native And Invasive Rubus (Rosaceae), Ashley A. Wint

Masters Theses & Specialist Projects

Invasive species are an increasing threat to biological diversity as well as a leading cause of recent species’ extinctions. Invasives spread quickly and efficiently, and the U.S spends millions of dollars annually in the control and eradication of these species. More information is necessary in order to predict which species may become invasive. Rubus (Rosaceae) was chosen for study because this genus includes various ploidy levels, reproductive modes, and species that are invasive as well as native.

Three Rubus species were chosen to represent apomictic and tetraploid invasives (Rubus armeniacus), a sexual and diploid native species (R. occidentalis), and a …
