Method Details

energyAtTrophicLevel

public static Real energyAtTrophicLevel(double initialEnergy,
 int level)

Lindeman's Efficiency (10% rule). Energy at Nth level = Initial * 0.1^(N-1)

shannonIndex

public static Real shannonIndex(double[] speciesCounts)

Biodiversity Index (Shannon-Wiener). H = -Sum(pi * ln(pi))
