Not just current PAMs but also future PAMs. PAMs can be built using species range predictionsbased on climate scenarios

Species Richness calculated from PAMs for Brassicaceae for three climate scenarios

Not just ranges and richnessMost existing indexes of biodiversity patterns can be calculated as

combinations of vectors from the PAM

PAM, site i, species j

Matrix of shared species in sites, NxN, where N are sites

Matrix of co-occurrence of usage of sites by species, SxS, where S are species

Species richness vector

Range size of each species

Using these simple relations we can obtain two other vectors.

1. The total sum of shared range sizes or Dispersion Field2. The total number of shared community compositions or Diversity Field

Diversity of sites and ranges of species are linked by a correlation between species diversity of sites and the mean range size of species occurring there; and by correlating the range size of species and the mean species diversity within those ranges. These relationships canbe illustrated in range-diversity plots where the dispersion of points are defined by the degreeof association among species, and the similarity of sites.
