Pro Tips
Typical values for real ecosystems range between 1.5 and 3.5.
A value of 0 indicates a community with only a single species.
Ensure all counts are positive integers for accurate results.
Higher H values indicate higher diversity and complexity.

Fun Facts
"Tropical rainforests typically have very high Shannon indices."
"Evenness (E) ranges from 0 to 1, where 1 is perfectly balanced."
"Diversity indices help conservationists prioritize habitats for protection."
"Shannon was an information theorist; the formula is based on entropy."
Formula: H = -Σ pi * ln(pi)
