For beta diversity, the difference between plots in structural richness and in cover of thick tussocks grasses and lawns were the best predictors (r2 = 0.45).
Alpha diversity was highest in sites on shallow soils with high structural richness (i.e. high number of cover categories), half covered by lawns, at sunny slopes and rough landscapes (r2 = 0.66).
His works acquired a great structural richness, with shapes and volumes devoid of rational rigidity or any classic premise.
In banana peels, chlorophyll catabolites were found in an unprecedented structural richness: a variety of new fluorescent chlorophyll catabolites (FCCs) and nonfluorescent chlorophyll catabolites (NCCs) were detected.
Metagenomics has enriched our knowledge of environmental microbiology through the structural (gene/species richness and distribution) and functional (metabolic) profiling of complex environmental microbial communities.
Treatment frequency showed strongly negative relationships with species richness, structural diversity and evenness, and horizontal and vertical understory cover, particularly that of slowly recovering species.
Considering that species richness fosters structural heterogeneity and structure, which, in turn can increase stand productivity even more, the combination of tree species richness and structure would be recommended while keeping in mind that other ecosystem services also benefit from species richness and structure, e.g., stability and the distribution of risk.
Not only is the paradigm of a multi-functional forest reinforcing the interest in the relationship among productivity, species richness, and structural diversity, but also the evidence that species mixing and structural diversity can increase productivity.
This enhancement of structural persistence by taxon richness must, however, be viewed with caution, since it interacts significantly with functional richness.
Daft, R. L. & Lengel, R. H. organizational information requirements, media richness and structural design.
The structural rigour but sonic richness of the Sonatas and Interludes are some of the most immediately attractive music of this last century; I'd say the same about Cage's magical, austere String Quartet in Four Parts.
