ecotraj

Assists in the analysis of temporal changes (i.e. dynamics) of ecological entities, defined as trajectories on a chosen multivariate space, by providing a set of trajectory metrics and visual representations.

Ecological Trajectory Analysis using the ecotraj R package

The main aim of the course is to provide an introduction to the concepts, geometric elements and statistics of the Ecological Trajectory Analysis (ETA) framework, including its extension to cyclical dynamics (CETA).

vegclust
vegclust

A set of functions to perform fuzzy clustering of vegetation data and to assess ecological community similarity on the basis of structure and composition.

indicspecies
indicspecies

Functions to assess the strength and statistical significance of the relationship between species occurrence/abundance and groups of sites. Also includes functions to measure species niche breadth using resource categories.
