Multilocus species delimitation and hybridization test of the five <i>Lucanus</i> taxa. Cheng-Lung Tsai Wen-Bin Yeh 10.1371/journal.pone.0156600.g005 https://plos.figshare.com/articles/figure/Multilocus_species_delimitation_and_hybridization_test_of_the_five_i_Lucanus_i_taxa_/3414478 <p>The species delimitations suggested by *BEAST and PTP are shown at the right side of the phylogram. STRUCTURE analysis assumed the optimal Bayesian clustering (K = 2) of the addressed five taxa. Each bar stands for a single individual. Morphological taxa are represented by different colors. The two groups found in <i>L</i>. <i>k</i>. <i>piceus</i> by PTP are represented by a dashed line.</p> 2016-06-03 11:23:34 differentiation taxonomic Formosa Island Taxonomic debates population structure mitochondrial genes Montane Stag Beetles Subspecific Differentiation Events subspecies kanoi Formosan stag beetles i.e subspecific status COI rDNA monophyletic ogakii davidi montane stag beetles periodical Pleistocene glaciations subspecific split events Bayesian-based species delimitation scenario
