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

Population Growth Rate Calculator

Compute the exponential growth rate r from initial and final population sizes over a time interval, as r = ln(N_final / N_initial) / t. Useful for bacterial cultures, microbial fermentation, cell-culture monitoring, and any closed system in exponential phase.
