Axis 1: Eigenvalue = 5.7; percent of variance explained = 47.6.
Axis 2: Eigenvalue = 1.9; percent of variance explained = 16.0.
Bold arrows represent correlations between ordination axes and variables listed in Table 3.
Ordinary lines represent correlations between use categories of Cook (1995) as modified by de la Torre (2008) and ordination axes.
Toxic NV=Toxic to nonvertebrates.
Toxic V=Toxic to vertebrates.
Otherwise, full names of the use categories are given in the Figure.
