Soils and Biodiversity

Abstract

Biological diversity or ‘biodiversity’ is described as “the variability among living organisms from all sources, whether terrestrial, aquatic or marine”. It includes the diversity within species (genetic diversity), between species (organism diversity) and of ecosystems (ecological diversity). Soil is one of nature’s most complex ecosystems and one of the most diverse habitats on earth: it contains a myriad of different organisms, which interact and contribute to the global cycles that make all life possible. Nowhere in nature are species so densely packed as in soil communities; however, this biodiversity is little known as it is underground and largely invisible to the human eye.
