wereused: tree reconciliation analysis, with Component version 2.0 (Page 1993a),
and paralogy-free subtree analysis, with TASS (Nelson and Ladiges 1995) and
Hennig86 1.5 (Farris 1988).
Component version 2.0 produced one general area cladogram (
fig. 5.16b
),
minimizing the number of terminal taxa added, and two general area cladograms
(
fig. 5.16c
and
fig. 5.16d
)
, minimizing the number of losses. The parsimony ana-
lysis of the matrix obtained with TASS led to a single general area cladogram (
fig.
5.16e
), with nineteen steps, a consistency index of 0.73, and a retention index
of 0.78. Items of error were calculated for the general area cladograms, and the
first one (
fig. 5.16b
) was chosen for having the smallest number. The sequence
of areas in the general area cladogram was as follows: (Coastal Desert (Caatinga
(Cerrado (Chaco ((Caribbean, Amazonian) (Parana, Atlantic)))))).
