How to say "biodiversity" in Japanese

• 生物多様性せいぶつたようせい
  no-adjectiveThe term for biodiversity as a concept: the variety of living things in a particular habitat, region or ecosystem. Typical of ecology, conservation and environmental writing, including discussion of its loss.
• 生物学的多様性せいぶつがくてきたようせい
  nounA close, word-for-word equivalent of the English phrase 'biological diversity', denoting the same scientific concept. Because it is less common and reads as a direct translation, 生物多様性 is usually the better choice.

For biodiversity as a concept — the variety of life in an ecosystem — 生物多様性 is the word to use; 生物学的多様性 is a more literal rendering of 'biological diversity' and is seldom needed.
