Figure 6

CanSINE insertion sites incongruent with prior phylogenic analyses. The model topologies shown are based on maximum-likelihood reconstruction using 18,853 bp of nuclear DNA, with bootstrap scores noted to the left of each node and divergence time estimates between nodes in gray (Johnson et al 2006) [66]. A) An insertion at locus 106256 is present in L. canadensis (N=22), polymorphic in L. lynx (N=23) and absent in L. pardinus (N=8), while another insertion near the same site is absent from L. canadensis, polymorphic in L. lynx and present in L. pardinus. A third insertion at locus 134463 is present in all L. canadensis and L. lynx and absent in all L. pardinus. B) An insertion at locus 133135 has a paraphyletic distribution among the ocelot lineage species; Leopardus pardalis (N=10), L. jacobita (N=2), L. tigrina (N=9), L. guigna (N=3) and L. geoffroyi (N=11), L. wiedii (margay, N=6) and L. colocolo (pampas cat, N=3). The placement of L. jacobita and L. colocolo with respect to the remaining Leopardus species has yet to be determined with statistical confidence and thus is depicted here as a polytomy. C) An insertion at locus 161275 is present in all P. viverrinus (N=7), absent in P. planiceps (N=5) and polymorphic among P. bengalensis (N=9) and P. rubiginosus (N=2). However, 4 other SINE insertion sites support the monophyly of Prionailurus and one insertion supports the monophyly of P. bengalensis, P. viverrinus and P. planiceps.
