Biology
Shannon Diversity Index Calculator
Compute the Shannon (Shannon-Wiener) diversity index H' for three species from their abundance counts. Higher values indicate greater diversity; 0 means a single-species community.

Biology
Leaf Area Index Calculator
Computes the Leaf Area Index (LAI) by dividing total one-sided leaf area by the ground surface area beneath a plant canopy. Widely used in ecology, agronomy, and remote sensing to estimate canopy density and productivity.
