Fidelity is the most fundamental notion of the Braun-Blanquet school of phytocoenology. It can be applied to all non-phenotypic taxa and to all syntaxa irrespective of their rank. This holds both for faithful and for differential taxa. In the latter case the range of syntaxa within which the taxon is differential should also be indicated. Not only taxa, but also their growth-form and microhabitat may be characteristic for a given syntaxon. A new concept: ‘elementary coenological unit’ (ECU) is… 
Determination of diagnostic species with statistical fidelity measures
Abstract Statistical measures of fidelity, i.e. the concentration of species occurrences in vegetation units, are reviewed and compared. The focus is on measures suitable for categorical data which

Statistical Measures of Fidelity Applied to Diagnostic Species in Plant Sociology
The idea of a diagnostic species is an important concept in plant sociology. However, since over a century ago, when the term “association” was introduced, the identification of diagnostic species
Let the concept of indicator species be functional
TLDR
A two-step procedure for incorporating the functional traits of a given species in the evaluation of its diagnostic value and shows that this subset of species appears to better characterize the functional ecology of coastal dune plant assemblages and shows a higher diagnostic value in comparison with those obtained through the traditional indicator analysis.
OptimClass: Using species‐to‐cluster fidelity to determine the optimal partition in classification of ecological communities
Question: Community ecologists are often confronted with multiple possible partitions of a single set of records of species composition and/or abundances from several sites. Different methods of
Fidelity and diagnostic species concepts in vegetation classification in the Rocky Mountains, northern Utah, USA
TLDR
A classification of the vegetation of a mountainous area of north- ern Utah is developed and compared the diagnostic species approach with the indicator-species approach of habitat type classification prevailing in the U.S. Interior West, finding vegetation units to be more strongly associated with the underlying environment than major habitat types sensu Daubenmire.
Symphyotrichum ciliatum in Romania: trends of spread and invaded plant communities
TLDR
This study has analysed the invasion history, current distribution in Romania, habitat preferences and the associated plant communities of Symphyotrichum ciliatum and confirmed its invasive character.
Plant communities in gradients
TLDR
The results show that, in most cases, the turnover of species composition along the gradient, according to the integrative concept, is due to species interactions, which enables the detect and describe discrete plant communities in terms of the central European Braun-Blanquet method.
Effects of different fidelity measures and contexts on the determination of diagnostic species
Question: How different are lists of diagnostic species of vegetation units, derived using various fidelity measures, in different contexts and with presence/absence versus cover data? Methods: Six

The importance of closely related taxa for the delimitation of phytosociological units
TLDR
Closely related taxa used in the phytosociology will not show any new criteria for delimitation of vegetation units, but often increase the number of characteristic components and actual limits of a given unit become better documented and more ecological information will be gathered.
Ordination of Plant Communities on the Basis of Their Plant Genus, Family and Order Relationships
TLDR
In phytosociology the plant species is generally considered the basic unit in the characterisation of phytOSociological units and is the type of attribute with which the vegetation is described, typified, and interpreted.

TLDR
The book is a detailed summary of research methods together with a critical evaluation of each proposal, and much sound philosophizing, and it is to be hoped that a clear definition of terms is decided upon at the forthcoming Cambridge conference.
TABORD, a program for structuring phytosociological tables
TLDR
TABORD is considered a numerical elaboration of the intuitive table sorting procedure according to the Braun-Blanquet method and its results confirmed in a concise way what was shown inthe original treatment through many separate analyses.
Indicator species analysis, a divisive polythetic method of classification, and its application to a survey of native pinewoods in Scotland
TLDR
The method has been applied to a survey of the native pinewoods of Scotland and provided a means of pigeon-holing the stands into acceptably homogeneous groups as a basis for further, more detailed, studies.

Higher taxonomic descriptors for vegetation classification
TLDR
Taxonomic ranks from species to superorder were evaluated for their usefulness as ecological descriptors and recognition of monophyletic higher taxa and the characteristics by which they may be recognized is recommended.
