Biology
Shannon Diversity Index Calculator
Computes the Shannon diversity index (Hβ²) from the individual counts of up to three species in an ecological community. Use it in field ecology to compare habitat quality or monitor biodiversity over time.

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.
