Matthew Amato, Joseph Carrasco, Carmen Sabedra & Cody Onufrock. Abstract. The question posed is, What is the Makeup of the Community of Organisms Living on rock substrate near the post in the Long Beach High School Pond? Organisms were collected and identified by using DNA barcoding. With the DNA from the collected organisms, via gel electrophoresis, traces of viable DNA were discovered . When gels were run, only one sample of six had worked. Because of the wide range of organisms collected, it was concluded that the community surrounding the post is diverse and strong enough to support a multitude of different species. The most important finding from this research was coincidentally, the only organism that worked during gel electrophoresis.( This organism, PAZ-01, was the only organism that was not identifiable as an animal or plant using .
