Chinas biodiversity conservation in the process of . . . Species diversity includes two aspects: (1) refers to the species richness, which can be called regional diversity (2) It refers to the uniformity of species distribution in ecology, called ecological diversity or community species diversity (W Ru et al , 2000) The modes and principles of species biodiversity are changeable
SCIENTIFIC CORRESPONDENCE - Nature found in a sample of 100 individuals, as a guide to species numbers, inferring that more species are present when E(S 100) is higher But E(S100) measures evenness, not species richness Very
