| Abstract | Alligator Weed (Alternanthera philoxeroides) is an invasive perennial plant of the Amaranthaceae family that is found in multiple climates. It was originally discovered in the Parana River region of South America, but has been studied the most in China. The concern for the invasion of alligator weed is due to the economic and environmental threats it poses. Our hypothesis is that the adaptability of populations affects the spread of the aquatic species. We looked at the population dynamics of alligator weed in three states: Mississippi, Kentucky, and Tennessee. The population dynamics were compared to see if there is a significant difference between the growth rates, suggesting adaptation. A population that has greater adaptation will be more invasive. We expected to find that Mississippi has greater adaptability to different climates, because its population has been in the United States longer. |
