Carbon emission calculator This online calculator allows you to calculate carbon emissions from measurements obtained by the static chamber (closed-chamber) method. |

Sсhorygin similarity coefficient for a series of samples This online calculator allows you to use a table of species distrubution in samples to calculate the Schorygin coefficient (or commonality coefficient of specific abundance) in pairs for each pair in a series of samples. |

Jaccard index The Jaccard index refers to binary similarity coefficients and is a commonly used measure for analyzing the species composition of communities or samples in biological studies. This similarity measure is the intersection of sets. The calculator is designed primarily for biologists, but is universal for estimating the intersection of sets and can be applied to other, non-biological problems. |

Palyi-Kownacki dominance index This calculator allows you to calculate species dominance using the two indicators most commonly considered in community analyses, species occurrence and abundance. |

Malthusian equation This online calculator calculates the unknown parameter of the Malthusian equation from the known parameters. |
