Simpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species.

A more diverse population consisting of many species of plants has a better chance of including individuals that might be able to adapt to changes in the environment. How to Calculate a Biodiversity Index main content. Taxonomic Diversity. A wide variety of species will cope better with threats than a limited number of them in large populations. Biodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. There are a number of other options that may be used (such as species richness and Shannon's Diversity Index), but the AP Biology Equation and Formula Sheet includes Simpson's, so AP Biology students should be prepared to use it for the AP Biology exam. New York, NY 10024-5102 Read more about health and safety. The resultant diversity indices are a key feature of communities which can throw light on many aspects of conservation. Every species matters, and the Museum is doing its bit to fight for biodiversity. It includes all species of animals and plants, and the natural systems that support them. This time, humans rather than natural events are to blame. adotstarr_97 Everyday First Aid. The biodiversity index here is high, 5/5 = 1. Healthy ecosystems can also help us cope with the impacts of climate change. Biodiversity is the name we give to the variety of all life on Earth. It can help organisations to assess site biodiversity by providing a simple self-assessment survey, online data repository and results calculator. Overall biodiversity loss can speed up extinction. Simpson's Diversity Index (SDI) is one approach to quantifying biodiversity. For example, the Amazon rainforest very species-rich as it is home to 10 million species. Our scientists represent one of the largest groups in the world working on natural diversity and are at the forefront of digital, analytical and genomic technologies to expand our knowledge of nature. Geography / People and environment / Biodiversity; 11-14; View more. First, enter the number of species, and then enter the name you wish to give the species, if available, and the given populations for each of the species—in any given order. Virtually all of Earth’s ecosystems … European Wild Bird Indicators have been adopted by the EU as official biodiversity indicators. Nature around us isn't enough - we need a natural world that is complex, resilient, thriving and full of variety. Simpson's Diversity Index is a measure of diversity. For example, a 4 X 4 meter square area in a carrot patch has 300 carrot plants, all the same species. The International Union for Conservation of Nature (IUCN) is the global authority on the status of the natural world. Calculating a Biodiversity IndexA Biodiversity Index gives scientists a concrete, uniform way to talk about and compare the biodiversity of different areas. Biodiversity is in trouble in the UK and across the globe, and its loss can refer to local and worldwide extinctions. Different animals and plants in a habitat help to make that place stable and sustainable. C) The more species you have, the more diverse the area, right? In fact, at least 99% of all the organisms that have ever lived are now extinct. It has a very low biodiversity index of 1/300, or 0.003. Diversity index.
