DescriptionConcern over accelerating extinction rates and loss of species diversity on a global scale was the subject of E.O. Wilson's seminal volume Biodiversity (Wilson 1988). This work essentially transformed the term "biodiversity" into a household word as a short-hand for species diversity--or more simply, the full array and variety of living organisms on Earth. But the term biodiversity means much more than the complement of plant and animal species that one expects to find in some given area. The term now encompasses not only the diversity of species, but their genetic structure, the interaction of the biotic and abiotic components of the environment at the ecosystem level, and at an even higher level the array of communities and ecosystem processes and functions that make up the landscape or regional level of biological diversity. Such a detailed exploration of biodiversity is beyond the scope of this section.
