Table 1.

List of the variables recorded for the microhabitat analysis along with a brief description of how they were recorded. Loadings correspond to correlation coefficients between principal components and variables, respectively (importance cutoff limit: 0.2). Numbers 1–9 correspond to the arrows 1–9 in Fig. 5
