  2. Ecosystem diversity - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_diversity

    An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity .

  3. Biodiversity - Wikipedia

    en.wikipedia.org/wiki/Biodiversity

    An example of the biodiversity of fungi in a forest in North Saskatchewan (in this photo, there are also leaf lichens and mosses). Biodiversity is the variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. [1]

  4. Global biodiversity - Wikipedia

    en.wikipedia.org/wiki/Global_biodiversity

    Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent.

  5. Measurement of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Measurement_of_biodiversity

    Taxonomic diversity, that is the number of species, genera, family is the most commonly assessed type. [7] A few studies have attempted to quantitatively clarify the relationship between different types of diversity. For example, the biologist Sarda Sahney has found a close link between vertebrate taxonomic and ecological diversity. [8]

  6. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    Ecosystems, for example, contain abiotic resources and interacting life forms (i.e., individual organisms that aggregate into populations which aggregate into distinct ecological communities). Because ecosystems are dynamic and do not necessarily follow a linear successional route, changes might occur quickly or slowly over thousands of years ...

  7. Diversity index - Wikipedia

    en.wikipedia.org/wiki/Diversity_index

    A diversity index is a method of measuring how many different types ... for example, number of individuals, biomass or coverage. ... Environmental and Ecological ...

  8. Megadiverse countries - Wikipedia

    en.wikipedia.org/wiki/Megadiverse_countries

    The 17 countries identified as megadiverse by Conservation International. A megadiverse country is one of a group of nations that harbours the majority of Earth's species and high numbers of endemic species.

  9. Species richness - Wikipedia

    en.wikipedia.org/wiki/Species_richness

    Species richness is the number of different species represented in an ecological community, landscape or region. [1] Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions.
