Selecting indicator taxa for the quantitative assessment of biodiversity.

摘要: Introducing greater objectivity to selection of indicator taxa produces results that are likely reduce uncertainty, be more efficiently obtained and clearly communicated. Seven criteria presented can used objectively test the claim a given taxon is an ideal indicator: (i) well known stable taxonomy; (ii) natural history; (iii) readily surveyed manipulated; (iv) higher broadly distributed geographically over breadth habitat types; (v) lower specialized sensitive changes; (vi) patterns biodiversity reflected in other related unrelated taxa; (vii) potential economic importance. These have different priorities depending on which two general categories used. Monitoring places emphasis sensitivity change, inventory systematics. An index suggested by selecting accurately This based number successfully tested for proposed their priority.
