Credits for this Experiment:    This lab is part of a larger NSF project incorporating inquiry-based labs in the ecology labs in the Southern Illinois University at Carbondale life science courses. This lab arouse out of brain storming among the investigators (D. J. Gibson, .B.A. Middleton, G.W. Saunders, M. Mathis, W.T. Weaver, J. Neely, J. Rivera, and L.M. Ovler) who wanted to develop an ecological experiment for use in a field setting. Details of the NSF project can be found in Gibson et al. (1999). We thank J. Neely and J. Rivera for writing the student handouts used in this experiment. We thank K. Jacobson and W. Mulach for including this laboratory in the Biology 200b curriculum at Southern Illinois university at Carbondale. We thank B. Grant , D. Herzog, S. Musante, and an anonymous individual for reviewing this submission.

      Special thanks go to P.H. Williams for breeding fast plants at the University of Wisconsin for over thirty years and for developing scientific experiments using fast plants for use in natural science curriculums in elementary schools, middle schools, high schools, and colleges. Some of his college level experiments investigate evolution by artificial selection, inbreeding depression, and intraspecific competition.
