The variety of life in the world or in a particular habitat or ecosystem.

Refers to the range of genetic, species, and ecosystem variation.

The story behind the word. The term 'Biodiversity' is a contraction of 'biological diversity.' It was popularized by American entomologist Edward O. Wilson in 1985, who used it as the title for a national forum and subsequent book. While 'biological diversity' had been used earlier, Wilson's work cemented 'biodiversity' as the standard, concise term to describe the vast array of life on Earth.

Word relationships

Biological diversity: This is the full, less commonly used term from which 'biodiversity' is a contraction; they are essentially interchangeable.
Variety of life: A more general, less scientific phrase, but captures the core meaning.

Homogeneity: Refers to uniformity or lack of variety, directly opposite to the concept of biodiversity.

Collocations

rich biodiversity
loss of biodiversity
preserve biodiversity
genetic biodiversity
species biodiversity

Example sentences

"Protecting the coral reefs is vital for preserving marine biodiversity." Discussing the importance of natural habitats.
"The loss of biodiversity is a serious global concern, as it can destabilize ecosystems and reduce their resilience." Reporting on environmental conservation efforts.

Memory hook

Think 'BIO' (life) and 'DIVERSITY' (variety) – it's the rich variety of all life forms. Life's Variety

When not to use

Don't use it to refer to a single species or a small, homogeneous group of organisms; it implies variety across multiple levels.

Fun facts

Edward O. Wilson, who popularized the term, is often called the 'father of biodiversity'.
