Taxonomic Diversity. So no, you cannot just use ANOVA and t-tests to compare them. Learn how to compute measures of biodiversity such as species richness (S), Simpson's index of diversity (D), Shannon-Weiner index (H) and Evenness(E). UICN Fance - Gouvernance et Biodiversité 4 5 UICN France - Gouvernance et Biodiversité 1. At simplest level: biodiversity is the species richness. Often, such measures of biodiversity aim to compare assemblages from spatial and/or temporal distinct localities. Suppose one wishes to compare the number of tree species in two contrasting 10-ha forest plots. Alpha diversity: Ø Alpha diversity refers to number of species in a single community at a particular time. Teach students how to calculate this number themselves. Biodiversity is a contraction of biological diversity. This includes data on biodiversity and other factors, such as water quality, as well as satellite data and data from government agencies, long-term trials, and other scientific sources. 7. Ø. One needs methods to standardize such results in order to make them comparabel. Less biodiverse areas include deserts, icy areas, and the bottom of the ocean. One approach is to examine some number of individual trees at random within each plot, recording sequentially the species identity of one tree after another.

Calculating a Biodiversity Index A Biodiversity Index gives scientists a concrete, uniform way to talk about and compare the biodiversity of different areas. But the well-balanced species communities are becoming increasingly unstable. KEY CONCEPTS • Biodiversity is the variety of life and can be measured on multiple scales including genetic diversity, species diversity, and ecosystem diversity. So the word biodiversity means the variety of plants and animals in a habitat. The term “biodiversity” comes from “biological diversity,” and refers to the variety of life on Earth at all levels — genes, ecosystems, you name it. The biodiversity index here is high, 5/5 = 1. According to the World Health Organisation (WHO), London is just a mid-table city when it comes to the international league table of polluted places. A common measure of this variety, called species richness, is the count of species in an area. Maybe it has been unpublished?

A comparison of one or all of these measures of biodiversity can illustrate changes in water quality conditions within a local community. Most research focuses on rural hedges, with comparatively little known about hedges in urban areas, or how hedges from these two environments compare. This lesson is a foundation to that knowledge. But just what is biodiversity anyway, scientifically-speaking? Provide one example of each. It also includes the evolutionary, ecological, and cultural processes that make sure life is able to be sustained. 8. The key difference between biodiversity and species richness is that biodiversity refers to the variety of life found in a specific place on Earth or the total variety of life on Earth while species richness refers to the number of different species represented in an ecological community, landscape or region.. Biodiversity and species richness are two different terms in ecology. How do biologists and conservationists measure it to determine which ecosystems are “the most” biodiverse? At site 1, I detected 52 species, and over 700 individuals. The closer D is to 1, the more diversity a population has. Biodiversity is the variety of life on Earth, in all its forms and all its interactions.
