TLDR
After pointing out the key assumptions underlying CCA, the paper focuses on the interpretation of CCA ordination diagrams and some advanced uses, such as ranking environmental variables in importance and the statistical testing of effects are illustrated on a typical macroinvertebrate data-set.Citations

Experimental Design and Data Analysis for Biologists
Gerry P. Quinn,Michael J. Keough +1 more
TL;DR: An essential textbook for any student or researcher in biology needing to design experiments, sample programs or analyse the resulting data is as discussed by the authors, covering both classical and Bayesian philosophies, before advancing to the analysis of linear and generalized linear models Topics covered include linear and logistic regression, simple and complex ANOVA models (for factorial, nested, block, split-plot and repeated measures and covariance designs), and log-linear models Multivariate techniques, including classification and ordination, are then introduced.

A protocol for data exploration to avoid common statistical problems
TL;DR: A protocol for data exploration is provided; current tools to detect outliers, heterogeneity of variance, collinearity, dependence of observations, problems with interactions, double zeros in multivariate analysis, zero inflation in generalized linear modelling, and the correct type of relationships between dependent and independent variables are discussed; and advice on how to address these problems when they arise is provided.

Multivariate Analysis of Ecological Data
Jan Lepš,Petr Šmilauer +1 more
TL;DR: In this paper, the authors present a study material for the participants of the course named Multivariate Analysis of Ecological Data that we teach at our university for the third year, which provides an easy-to-read supplement for the more exact and detailed publications like the collection of the Dr. Ter Braak' papers and the Canoco for Windows 4.0 manual.
Book
Analysing Ecological Data
TL;DR: In this paper, the effects of rice farming on aquatic birds with mixed modelling were investigated using additive and generalised additive modeling and univariate methods to analyse abundance of decapod larvae.

Spatial prediction of species distribution: an interface between ecological theory and statistical modelling
TL;DR: In this article, an ecological model concerning the ecological theory to be used or tested, a data model concerning collection and measurement of the data, and a statistical model concerning statistical theory and methods used.

Canonical Correspondence Analysis: A New Eigenvector Technique for Multivariate Direct Gradient Analysis
TL;DR: In this article, a new multivariate analysis technique, called canonical correspondence analysis (CCA), was developed to relate community composition to known variation in the environment, where ordination axes are chosen in the light of known environmental variables by imposing the extra restriction that the axes be linear combinations of environmental variables.
Journal ArticleDOI
Partialling out the spatial component of ecological variation
TL;DR: In this paper, a method is proposed to partition the variation of species abundance data into independent components: pure spatial, pure environmental, spatial component of environmental influence, and undetermined.

Detrended correspondence analysis: an improved ordination technique
M. O. Hill,Hugh G. Gauch +1 more
TL;DR: DCA consistently gives the most interpretable ordination results, but as always the interpretation of results remains a matter of ecological insight and is improved by field experience and by integration of supplementary environmental data for the vegetation sample sites.
Book
Data Analysis in Community and Landscape Ecology
TL;DR: The aim of this book is to provide a history of numerical methods in practice in the context of ecological data collection and its application to Dune meadow data.
