Cheat Sheet
- Shannon Diversity Index -
The Shannon Diversity Index (H') measures species richness and evenness in a community using H' = - Σ pi ln(pi), where pi is the proportion of each species. Mnemonic: "Shannon shares the log" to recall the logarithmic component. Practice calculating H' for a sample community in biodiversity practice problems to sharpen your skills.
- Simpson's Diversity Index -
Simpson's Index (D) quantifies diversity as D = Σ pi², emphasizing dominant species; lower D indicates greater diversity. Remember "Simpson spots the squares" to recall the squared proportions. Use sample datasets in biodiversity questions to compare D and 1 - D for practice.
- Species Richness vs. Evenness -
Species richness counts the number of species while evenness gauges their relative abundance; high richness with low evenness can mask dominant species. A helpful phrase: "Rich in species, even in spread." Try classifying communities in biodiversity quiz questions to differentiate these metrics.
- Keystone Species Impact -
Keystone species exert disproportionate effects on ecosystem structure despite low abundance, like wolves in Yellowstone shaping vegetation and animal behavior. Think "keystone keeps it together" to remember their pivotal role. Explore case studies in questions for biodiversity to see how removing keystones alters diversity.
- Biodiversity Hotspots & Conservation -
Myers et al. (2000) defined biodiversity hotspots as regions with ≥1,500 endemic vascular plants and ≥70% habitat loss, including 34 global hotspots like Madagascar. Use the "Hotspot 1500 - 70" mnemonic to recall criteria. Applying these in biodiversity practice problems helps prioritize conservation strategies.
