Measuring biodiversity using R: A Comparison of Diversity in Primary and Secondary Tropical Forests
This exercise is both a lesson in tropical forest restoration and a data analysis of metrics of biodiversity using R. The exercise contains background information, including two powerpoint presentations, real data from the Bilsa rainforest in Ecuador on tropical bird diversity, and a guided tutorial for the use of R to analyze biodiversity metrics. The module also includes the complete R script with instructional notations as well as all necessary data files. By completing this exercise, students will:
1. Distinguish some ways in which biological diversity can be quantified.
2. Manipulate a real data set to quantify diversity, including the calculation of diversity indices.
3. Identify and recommend conservation practices using the results.
4. Use the powerful open-source statistics program R.
