    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 .

Ecologists study many diverse and complex relations among species, such as predation and pollination. The diversity of life is organized into different habitats, from terrestrial to aquatic ecosystems.

  7. 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]

  8. 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.

  9. Nature conservation - Wikipedia

    en.wikipedia.org/wiki/Nature_conservation

    Philosophers have attached intrinsic value to different aspects of nature, whether this is individual organisms (biocentrism) or ecological wholes such as species or ecosystems (ecoholism). [ 9 ] More utilitarian schools of conservation have an anthropocentric outlook and seek a proper valuation of local and global impacts of human activity ...
