The ade4 Package: Implementing the Duality Diagram for Ecologists
TLDR
The theory of the duality diagram is presented and its implementation in ade4 is discussed, which follows the tradition of the French school of "Analyse des Donnees" and is based on the use of theDuality diagram.
Spatial modelling: a comprehensive framework for principal coordinate analysis of neighbour matrices (PCNM)
Spatial structures of ecological communities may originate either from the dependence of community structure on environmental variables or/and from community-based processes. In order to assess the
Variation partitioning of species data matrices: estimation and comparison of fractions.
TLDR
It is shown that variation partitioning as currently applied in canonical analysis is biased, and appropriate unbiased estimators are presented to consider so that comparisons between fractions or, eventually, between different canonical models are meaningful.
Testing the species traits-environment relationships: the fourth-corner problem revisited.
TLDR
An extension to measure the link between species traits and environmental variables when the ecological community is described by abundance data is presented and a new multivariate fourth-corner statistic is proposed.
How to measure and test phylogenetic signal
TLDR
These guidelines aim to better assess phylogenetic signal and distinguish it from random trait distributions and are developed under the assumption of BM, and additional simulations with more complex trait evolution models show that they are to a certain degree generalizable.
The global spectrum of plant form and function
TLDR
Analysis of worldwide variation in six major traits critical to growth, survival and reproduction within the largest sample of vascular plant species ever compiled found that occupancy of six-dimensional trait space is strongly concentrated, indicating coordination and trade-offs.
CO‐INERTIA ANALYSIS AND THE LINKING OF ECOLOGICAL DATA TABLES
TLDR
The co-inertia criterion for measuring the adequacy between two data sets is presented and can be easily extended to the cases of distance matrices or to the case of more than two tables.
Community ecology in the age of multivariate multiscale spatial analysis
Species spatial distributions are the result of population demography, behavioral traits, and species interactions in spatially heterogeneous environmental conditions. Hence the composition of
