I went on a class field trip to Fernwood Botanic Garden in southwest Michigan when I was in sixth grade. When we toured the restored prairie, the naturalist told us about invasive non-native plants such as garlic mustard and how they destroy native habitats. Most of my class was bored, but I was amazed. I wanted to learn more, especially because my grandfather owns a section of prairie in southwest Michigan. About five years ago, he completed a prairie restoration on some of his land, and I wanted to know if he also had non-native plants growing in his prairie.

Puerto Rico is home to three bioluminescent bays, protected inlets that hold millions of marine bioluminescent dinoflagellates. These bays are huge tourist attractions, and swimming in them, when permitted, is popular. Often the visitors have sprayed themselves with insect repellants containing the active ingredient DEET. The purpose of this paper is to examine the effects of DEET on the ability of the dinoflagellates to emit light.
