Associations between species and groups of sites: indices and statistical inference.

  title={Associations between species and groups of sites: indices and statistical inference.},
  author={Miquel De C{\'a}ceres and Pierre Legendre},
  volume={90 12},
Ecologists often face the task of studying the association between single species and one or several groups of sites representing habitat types, community types, or other categories. [] Key Result Correlation measures, such as the phi coefficient, are more context-dependent than indicator values but allow focusing on the preference of the species. In contrast, the two components of an indicator value index directly assess the value of the species as a bioindicator because they can be interpreted as its…

Let the concept of indicator species be functional

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.

Improving indicator species analysis by combining groups of sites

This paper suggests improving indicator species analysis by considering all possible combinations of groups of sites and selecting the combination for which the species can be best used as indicator.

A weighting method to improve habitat association analysis: tested on British carabids

Analysis of species’ habitat associations is important for biodiversity conservation and spatial ecology. The original phi coefficient of association is a simple method that gives both positive and

Anopheles species associations in Southeast Asia: indicator species and environmental influences

Vegetation indices derived from satellite imagery proved very valuable with one variable explaining more variance of the species dataset than any other variable and could be improved by integrating seasonality in the sampling and collecting at least 4 consecutive days.

Using species combinations in indicator value analyses

This work presents a novel statistical approach to determine indicators of site groups using species data that allows indicators to be species combinations in addition to single species, and presents a simple algorithm that identifies the set of indicators that show high positive predictive value for the target site group.

Co‐occurrence patterns in a diverse arboreal ant community are explained more by competition than habitat requirements

This study assesses the potential role of interspecific competition and habitat selection on the distribution patterns of an arboreal ant community by incorporating habitat attributes into the co‐occurrence analyses, and suggests that competition is the most important influence on the Distribution patterns ofArboreal ants within the focal community.

Limitations to the use of arthropods as temperate forests indicators

The suitability of arthropods as indicators for particular forest types based on a comprehensive standardized sampling of various taxa by different trap types in 93 mature temperate forest sites in three regions of Germany concluded that overall, arthropod indicators did not turn out to be reliable indicators, at least at the scale of Germany.



Indicator species analysis as a test of non-random distribution of species in the context of marine protected areas

The efficiency of this new approach within the framework of conservation and marine reserve studies is demonstrated by focusing on three species, Sciaena umbra, Palinurus elephas and Maja verrucosa.


A new and simple method to find indicator species and species assemblages characterizing groups of sites, and a new way to present species-site tables, accounting for the hierarchical relationships among species, is proposed.

Quantifying habitat specificity to assess the contribution of a patch to species richness at a landscape scale

Assessing and predicting the species richness of a complex landscape remains a problem because there is no simple scaling function of species richness in a heterogeneous environment. Furthermore, the

Statistical determination of diagnostic species for site groups of unequal size

Abstract Aim: Concentration of species occurrences in groups of classified sites can be quantified with statistical measures of fidelity, which can be used for the determination of diagnostic


Many organisms display patchiness in their distribution patterns over a wide range of spatial scales. Patchy distribution patterns can be caused by processes such as growth, migration, reproduction,

Assessing species diagnostic value in large data sets: A comparison between phi-coefficient and Ochiai index

Abstract Question: Diagnostic species are useful tools for the identification and ecological interpretation of community types. Vegetation databases facilitate the computation of diagnostic values of

Habitat associations of trees and shrubs in a 50‐ha neotropical forest plot

To the extent that habitat association reflects habitat specialization, the results suggest that local habitat specialization plays a limited role in the maintenance of species diversity in this forest.

The verification and application of bioindicators: a case study of dung beetles in a savanna ecosystem

The indicator value (IndVal) method is used to assess the indicator responses of dung beetles in Tembe Elephant Park, South Africa, and concludes that both characteristic and detector species are useful bioindicators of habitat quality and conversion.

Context-dependence of diagnostic species: A case study of the central european spruce forests

In the phytosociological literature, there are numerous different approaches to the designation of diagnostic species. Frequently, this results in discrepancies between the lists of diagnostic

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
