Ecology and Evolution Practice Problems Attached is a real data set from a vegetation sampling study conducted in four different woody plant communities in central Texas. This sampling was conducted by inventorying a number of 10 x 10 m quadrats. The data have been summarized for you in the attached table. For each community type determine: I. The dominant or co-dominant species 2. The species richness (# species) 3. Th 4. The Simpson’s Dominance Index (D) e species diversity (Shannon-Weiner Diversity Index [H’] 5. Which community is the most diverse and how are diversity and dominance related? Use the following equations for the above indices: Where, p= Importance Value (IV) for each species/Total IV for all species In = logarithm to the base e Note: These indices have no units.
