Chapter 4 Intro: Multivariate analyses
For instance, our research question might be:
How does the bacterial composition on maple leaves changes along the elevational gradient?
What is the compositional dissimilarity of the bat communities?
How closely-related spider local communities are in relation to their composition?
In all these cases, the outcome is composed of several variables, e.g. usually a sample-by-species or sample-by-environment matrix.
