Traditionally, ecologists have measured biodiversity by taking into account both the number of species and the number of individuals of each species. However, biologists are using different measures of biodiversity, including genetic diversity, to help focus efforts to preserve the biologically and technologically important elements of biodiversity.

(A) Seven ecosystems with foundation species were sampled: coastal (seagrass, blue mussel, cordgrass), freshwater (watermilfoil, water-starwort) and terrestrial (Spanish moss, marram grass). (B) Food webs were constructed for both bare and foundation species-dominated replicate areas. (C) From each foundation species structured-food web, nodes (species) were randomly removed until the s…

In most cases, numerous species share a habitat. The interactions between these populations play a major role in regulating population growth and abundance. All populations occupying the same habitat form a community: populations inhabiting a specific area at the same time. The number of species occupying the same habitat and their relative abundance is known as species diversity.

However, it is common for conservation biologists to speak of species diversity even when they are actually referring to species richness.

Each biome's characteristics, like the nutrient-poor tropical rain forest and adaptable desert ecosystems, highlight species and environmental interactions.

Measuring biodiversity on a large scale involves measuring ecosystem diversity (the number of different ecosystems on Earth), Species diversity (the number of different species in a particular area and their relative abundance), and genetic diversity (a measure of the variability among ind
