BIODIVERSITY IN THE AGE OF ECOLOGICAL INDICATORS

摘要

The multifarious nature of biodiversity is considered in relation to difficulties of definite determination and managerial mandates for monitoring.At a micro scale there is some convergence with the concept of community,but the linkage is largely lost in the spectra of temporal scope,spatial scales,successional seres,and taxonomic trajectories.Practicality points to selecting suitable suites of indicators as surrogates for particular purposes.Domains of partial ordering on multiple indicators constitute comparable collectives,whereas different domains require recognition of special situations.Theoretical treatise and practical process can proceed in parallel,with dialogue and cross-fertilization serving to invigorate and inspire;whereas compulsive concern for completeness and consistency can be counter-productive as well as unduly expensive.Inability to completely capture all aspects of biodiversity in one full formulation is interesting and integral to issues of biocomplexity.
