In this Issue, students will examine published data that address the ecological consequences of introduced species. Activities engage students in data analysis and hypothesis testing, and will increase their understanding of the complexities of ecological phenomena. This Issue focuses on ecological consequences of introduced species using several case studies - zebra mussels, brown tree snakes,...
In this TIEE experiment, students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic factors determine what organisms are present in a community.
Students will make and install artificial leaf packs in a stream, wait for the leaf packs to be colonized by stream organisms, measure...
This article illustrates how multiple methods can be used to assess student understanding of the “novel weapons hypothesis” presented in the Callaway and Ridenour review of theories regarding invasive plant species[attached]. The paper introduces students to concepts of natural selection, fitness, competition, and invasion of exotic species. The assessments we describe here engage students ...
