Examples of ordination techniques

Example 1: Canonical correspondence analysis applied on hunting spider data

Keywords: Species-environmental relationships. How to read a triplot and  a biplot. Canonical correspondence analysis.

Example 2: Discriminant analysis applied on Egyptian skulls of different time periods from the area of Thebes.

Keywords: Discrimination between groups of samples. Discriminant analysis. Hypothesis tests (is the discrimination significant?). Identification which variables contributed most to the discrimination.

Example 3: Zoobenthic species measured in an intertidal area  in Argentina. 

Keywords: Zoobenthic species-environmental relationships. When to use PCA and RDA and not CA or CCA? Biplots and triplots. Superimposing explanatory variables on a biplot. Indirect gradient analysis. Coenoclines. Discriminant analysis to detect differences in species behavior at 3 transects.

Example 4: Using coenoclines to detect linear or unimodal species-environmental relationships

Keywords: Coenoclines. Using PCA or CA? Using RDA or CCA?

Example 5: Variance partitioning for dune meadow data

Keywords: Identify the amount of variation in response variables due to a subset of explanatory variables. Partial CCA. Identify pure management effects, spatial effects, pure temporal effects, etc.

Further examples are in preparation.
