          Abstract

          Niviventer confucianus sacer Thomas, 1908, which has been regarded as a subspecies of N. confucianus , was found to be a distinct species from N. confucianus based on molecular, karyotyping, and morphological characteristics in this study. Niviventer c. sacer was found to belong to a distinct phylogenetic clade in phylogenetic tree constructed using the mitochondrial gene Cytb, it clustered with N. bukit (Bonhote, 1903) from Vietnam and N. confucianus (Milne-Edwards, 1871) from Yunnan, but showed a distant relationship with N. confucianus from adjacent areas. The genetic distance between N. c. sacer and N. confucianus was more than 5.8%, reaching the level of interspecific differentiation. The species delimitation indicates that N. c. sacer is a monophyletic group. The karyotype of N. c. sacer (FN = 55, 8m+4st+32t+X(sm)Y(t)) differed from that of N. confucianus (FN = 59, 6m+4sm+2st+32t+X(sm)Y(t)). In terms of morphological features, the length of incisive foramen (LIF) and length of auditory bulla (LAB) of N. c. sacer is significantly larger than that of N. confucianus and N. bukit ( P < 0.05) and the proportion of white tail tip to total tail length is significantly longer at N. c. sacer (≥ 1/3) than that at N. confucianus (≤ 1/3). Therefore, integrated analysis confirmed that N. c. sacer is a distinct species of genus Niviventer rather than a subspecies of N. confucianus or N. bukit , namely N. sacer , which is only distributed in Shandong.

              The Role of DNA Barcodes in Understanding and Conservation of Mammal Diversity in Southeast Asia

              Background Southeast Asia is recognized as a region of very high biodiversity, much of which is currently at risk due to habitat loss and other threats. However, many aspects of this diversity, even for relatively well-known groups such as mammals, are poorly known, limiting ability to develop conservation plans. This study examines the value of DNA barcodes, sequences of the mitochondrial COI gene, to enhance understanding of mammalian diversity in the region and hence to aid conservation planning. Methodology and Principal Findings DNA barcodes were obtained from nearly 1900 specimens representing 165 recognized species of bats. All morphologically or acoustically distinct species, based on classical taxonomy, could be discriminated with DNA barcodes except four closely allied species pairs. Many currently recognized species contained multiple barcode lineages, often with deep divergence suggesting unrecognized species. In addition, most widespread species showed substantial genetic differentiation across their distributions. Our results suggest that mammal species richness within the region may be underestimated by at least 50%, and there are higher levels of endemism and greater intra-specific population structure than previously recognized. Conclusions DNA barcodes can aid conservation and research by assisting field workers in identifying species, by helping taxonomists determine species groups needing more detailed analysis, and by facilitating the recognition of the appropriate units and scales for conservation planning.
