In-Depth Information
García-Barros (2003) concluded that the results based on the PAE cladogram
were better than those based on the phenogram because the latter included some
areas based on absent species. In addition, the procedure of setting k = 0 was
more effective than PAE-PCE. He suggested that compatibility algorithms (e.g.,
CLIQUE from PHYLIP; Felsenstein 1993) may be more appropriate than those
based on parsimony for identifying areas of endemism.

Endemicity Analysis
Szumik et al. (2002) proposed a method that takes into consideration the
spatial position of the species in order to identify the set of grid cells that
represent an optimal area of endemism according to a score based on the
number of species endemic to it (Szumik and Roig-Juñent 2005). In order to
assign the values of endemicity to the sets of grid cells evaluated, Szumik
et al. (2002) suggested four criteria ( fig. 4.15a - 4.15d ):
1. First criterion ( fig. 4.15a ): The distribution of a species must adjust per-
fectly to the area to contribute to the score, so it must be present in all the
grid cells of the set.
2. Second criterion ( fig. 4.15b ) : A species can contribute to the score if it is
present in some grid cells outside the area as long as the cell is adjacent
to the area. This criterion does not require that all species contributing to
the score have identical distributions.
