1) taxonomic diversity 分类多样性 1. Using the calculation of the taxonomic grade number, the taxonomic pattern of genera, endemic genera and distribution of the protected species, thetaxonomic diversityin the three reserves are analyzed by the field investigation and reference data collection. ...
This investigation is a critical analysis focusing on the interrelations between species taxonomic diversity (based on the Shannon diversity index), cell size-based functional diversity (as a measure of Rao'sQ), species richness (number of species), and species dominance (as per McNaughton's ...

Taxonomic diversity, geographic distribution, and commercial availability of aquarium-traded species of caulerpa (Chlorophyta, Caulerpaceae) in souther...
.There is evidence from the fossil record to suggest that latitudinal gradients in taxonomic diversity may be time-invariant features, although almost certainly not on the same scale as that seen at the present day. It is now apparent that both latitudinal and longitudinalgradients increased dramatic...
Our assessment of morphological diversity is influenced by morphological extremes and therefore depends on sample size (taxonomic richness). Rarefaction predicts the morphological diversity that would probably be observed in a sample of reduced size, thereby allowing both compensation for differences in samp...
The results showed that (1) taxonomic diversity, functional dominance, functional diversity, and community aboveground biomass all increased from low to high precipitation grassland types; (2) there were significant positive linear relationships between taxonomic diversity, functional dominance, functional ...
Functional diversity was estimated as the degree to which species within the same community differed from each other with respect to their trait composition (functional dispersion). We used community-weighted means to test how the different traits were filtered by river damming. Furthermore, we ...
Plant taxonomic diversity (species richness and species diversity) explained more of the soil microbial diversity than the functional diversity and soil properties. Prediction of fungal richness was better than that of bacterial richness. In addition, root traits explained more variation than the leaf ...
Fungal diversity in GenBank is rather low; it keeps records for 24,288 species names only (25.09.2011), as compared with IndexFungorum database (www.indexfungorum.org) that contains more than 450,000 species names. In this context, it is clear that providing GenBank with information about ...
