Biogeography and the origin of extant species of the schismatoglottis nervosa complex (araceae : schismatoglottideae)
This study presents the phylogeny and biogeography of the Schismatoglottis Nervosa complex (Araceae: Schismatoglottideae) based on the nuclear ITS region and chloroplast regions (matK, trnL-F, psbA-trnH). The aim is to provide evidence for divergence and biogeographical implications of the comple...

| description | This study presents the phylogeny and biogeography of the Schismatoglottis Nervosa
complex (Araceae: Schismatoglottideae) based on the nuclear ITS region and chloroplast
regions (matK, trnL-F, psbA-trnH). The aim is to provide evidence for divergence and
biogeographical implications of the complex and to provide insight into the dispersal
evolution of the family. The Schismatoglottis Nervosa complex comprises eighteen
species endemic to several localities in Borneo and West Malaysia: Kuching (Bau,
Matang, Padawan, and Lundu), Serian, Bintulu, Sarikei, Kapit, Miri, Tawau and Perak.
Each species is endemic to specific substrate: shales, limestone, sandstone and granite.
Maximum parsimony analysis and maximum likelihood analyses were performed with
PAUP* 4.0b10 and RAxML blackbox, respectively. Bayesian analysis was generated
with MrBayes v3.2.7, divergence time estimation by BEAST, and distribution evolution
based on S-DIVA and LAGRANGE. Results from these analyses revealed that the
complex diverged from west to east (polarity from Malay Peninsula to Borneo) during
Pliocene (6 Mya) to Pleistocene (0.6 Mya) through re-emergence and submergence of land bridges. Divergence date estimates support a rapid radiation which very likely
catalyzed by geological history. |
