Relative Abundance Calculator

Calculate the relative abundance of species or items in a dataset, which is the proportion of each species relative to the total number of species.

Input Parameters

Species 1:

Calculation Results

Calculation Formula

Relative Abundance = Count of Species / Total Count of All Species

Where:
- Count of Species: The number of individuals of a particular species
- Total Count of All Species: The sum of individuals of all species in the dataset

Relative Abundance Calculator Usage Guide

Learn how to use the Relative Abundance Calculator and understand its applications in ecology and data analysis

How to Use

  1. Enter the name (optional) and count of each species or item in your dataset. You can add multiple species by clicking the "Add Species" button.
  2. Click the "Calculate" button to compute the relative abundance for each species.
  3. The results will show the percentage abundance of each species relative to the total count.
  4. Use the "Reset" button to clear all inputs and start over.

Applications

This calculator is particularly useful in ecology for:

  • Measuring species diversity in ecosystems
  • Comparing community composition between different sites
  • Tracking changes in species abundance over time
  • Analyzing environmental samples (soil, water, air)

Example

Suppose you have a soil sample with the following counts:

  • Arabidopsis thaliana: 150
  • Brassica rapa: 75
  • Lactuca sativa: 25

When you input these values, the calculator will show:

  • Arabidopsis thaliana: 60%
  • Brassica rapa: 30%
  • Lactuca sativa: 10%

Total count: 250
