The variety of life across all levels of organization from genetic diversity within populations, to species, which have to be regarded as the pivotal unit of classification, to ecosystems.
the variety and variability among living organisms and the ecosystems in which they occur. Biodiversity includes the numbers of different items and their relative frequencies; these items are organized at many levels, ranging from complete ecosystems to the biochemical structures that are the molecular basis of heredity. Thus, biodiversity encompasses expressions of the relative abundances of different ecosystems, species, and genes.
The variety of different species, the genetic variability of each species, and the variety of different ecosystems that they form.
The number and abundance of species found within a common environment. This includes the variety of genes, species, ecosystems, and the ecological processes that connect everything in a common environment.
the variety and complexity of species present and interacting in an ecosystem and the relative abundance of each
The variety of, and variability among, living organisms and the ecological complexes in which they occur. Biological diversity at its most basic level is the genetic diversity (genetic variation found within each species), phenotypic and morphological diversity (physical, life history and behavioral variation found within each species), species diversity (number of species in a given ecosystem), and community/ecosystem diversity (variety of habitat types and ecosystem processes extending over a region).
same as Biodiversity (see above)
Forest Stewardship] The variety of life forms in a given area. Diversity can be categorized in terms of the number of species, the variety in the area's plant and animal communities, the genetic variability of the animals, or a combination of these elements.
(wildlife science) Richness and abundance of species, and variety of natural communities. Both the number of species and the number of individuals within each species are important in considering the extent of biological diversity in an area. Also referred to as biodiversity.
A concept recognizing the variety of life forms in an area of the Earth and the ecological interdependence of these life forms.
The full range of variability within and among living organisms and the ecological complexes in which they occur. Biological diversity encompasses ecosystem or community diversity, species diversity, and genetic diversity.
Describes attributes of species richness, genetic variation, and complexity within an ecosystem.
The diversity of plants, animals and other living organisms in all their forms and levels of organization, including the diversity of genes, species, ecosystems, and the evolutionary and functional processes that link them.

The variety of different living organisms from all sources including terrestrial, marine and other aquatic ecosystems and the variety of different ecosystems that they form. This includes diversity within species, between species and of ecosystems, and the genetic variability of each species.
The variety and abundance of species, their genetic composition, their communities, and the ecosystems and landscapes of which they are a part. As used in this document, biodiversity refers to native biological diversity; therefore, increases in species diversity resulting from the introduction of nonnative species would not constitute an increase in biodiversity.
The variety and variability of the world's organisms, the ecological complexes in which they occur, and the processes and life support services they mediate.
The concept of multiple species of organisms living together in balance with their environment and each other.
The variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.
the variety of plants and animals, the communities they form and the ecological functions they perform at the genetic, stand, landscape, and regional levels.
See biodiversity. (Source: FAO, 1999)
the variety of life in all its forms, levels and combinations including ecosystem diversity, species diversity and genetic diversity
the variety and abundance of species, their genetic make-up, and the communities, ecosystems, and landscapes in which they occur. It also refers to ecological structures, functions, and processes at all levels, from a rotting log in a woodlot to a coral reef in the ocean.
The variety of all life forms â€“ the different plants, animals and micro-organisms, the genes they contain, and the ecosystems of which they form a part.
The variety of life forms and processes, including a complexity of species, communities, gene pools, and ecological functions. ( FEMAT, IX-3)
The number of species (plant or animal) and the number of individuals of these species.
Biological diversity means the variability among living organisms, and the ecological complexes of which they are a part, including diversity within species, between species, and of ecosystems.
The diversity of life often divided into three hierarchical levels: genetic (diversity within species), species (diversity among species), and ecosystems (diversity among ecosystems).
The variety of life forms: the different life forms including plants, animals and micro-organisms, the genes they contain and the ecosystems (see below) they form. It is usually considered at three levels – genetic diversity, species diversity and ecosystem diversity.
