 abstract = {Both the ordination of taxonomic tables and the measurements of species
diversity aim to capture the prominent features of the species composition
of a community. However, interrelations between ordination techniques
and diversity measurements are seldom explicated and are mainly ignored
by many field ecologists. This paper starts from the notion of the
species occurrence table, which provides a unifying formulation for
different kinds of taxonomic data. Here it is demonstrated that alternative
species weightings can be used to equate the total inertia of a centered-by-species
occurrence table with common diversity indices, such as species richness,
Simpson diversity, or Shannon information. Such an equation defines
two main ordination strategies related to two different but consistent
measures of species diversity. The first places emphasis on scarce
species and is based on Correspondence Analysis and species richness
(CA-richness strategy). The second, in which abundant species are
prominent, relies on Non-Symmetric Correspondence Analysis and Simpson
diversity (NSCA-Simpson strategy). Both strategies are suitable for
measuring ? and ? diversity by analyzing the centered-by-species
occurrence table with respect to external environmental or instrumental
variables.


In this paper, these two strategies are applied to ecological data
obtained in a Neotropical rainforest plot. The results are then discussed
with respect to the intrinsic characteristics of the community under
analysis, and also to the broad classes of floro-faunistic data used
in ecology (i.e., data gathered from museum or herbarium collections,
exhaustive inventories in a reference plot, or enumeration through
species-by-relevés tables). The approach encompasses several well-known
techniques such as Correspondence Analysis, Non-Symmetric Correspondence
Analysis, Canonical Correspondence Analysis, and Redundancy Analysis,
and provides greater insight into interrelations between ordination
methods and diversity studies.},
