Keanekaragaman spesies

Keanekaragaman spesies adalah jumlah dari spesies berbeda yang diwakili pada sebuah komunitas (sebuah dataset). Jumlah efektif spesies merujuk kepada jumlah spesies yang sama melimpahnya, yang dibutuhkan untuk mendapatkan kelimpahan spesies proporsional mean yang sama, sebagai yang diobservasi pada dataset yang menjadi perhatian (yang mana suatu spesies dapat tidak sama-sama melimpah). Arti dari keanekaragaman spesies dapat mencakup kekayaan spesies, taksonomi atau filogenetika, dan/atau kesetaraan spesies. Kekayaan spesies adalah sebuah perhitungan sederhana dari suatu spesies. Keanekaragaan taksonomi atau filogenetik adalah hubungan genetik diantara kelompok-kelompok spesies berbeda. Kesetaraan spesies menghitung seberapa seimbang kelimpahan spesies.[1][2][3]
