Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action 1,2 . Ongoing developments in taxonomy, threatening processes and research further underscore the need reassessment 3,4 Here we report findings second Global Amphibian Assessment, evaluating 8,011 International Union Conservation Nature Red List Threatened Species. We find that amphibians most threatened vertebrate class (40.7% globally threatened). The updated...
Despite considerable progress in unravelling the phylogenetic relationships of microhylid frogs, among subfamilies remain largely unstable and many genera are not demonstrably monophyletic. Here, we used five alternative combinations DNA sequence data (ranging from seven loci for 48 taxa to up 73 as 142 taxa) generated using anchored phylogenomics sequencing method (66 loci, derived conserved genome regions, Sanger (seven tackle this problem. We assess effects character sampling, taxon...
Within Sundaland, the species diversity of genus Megophrys is richest in Borneo, with some restricted to northern highlands island. On basis molecular, morphological and acoustic evidence, we describe a new large-sized Megophrys, once confused M. nasuta. The kalimantanensis sp. nov. can be differentiated from all its congeners by large genetic distance more than 6.11% mitochondrial 16S rRNA gene, much shorter rostral orbital appendages, unique advertisement call. This has been recorded...
A new species of Asian rock gecko, genus Cnemaspis, is described from Padawan, western Sarawak, Malaysian Borneo. The forms a clade with C. paripari and nigridia the group in mitochondrial DNA phylogeny similar to them morphologically some characters such as caudal scalation. It differs other Cnemaspis its unique combination snout-vent length (up 62.7 mm), 4-9 precloacal pores males, keeled subcaudals an enlarged, smooth, median row, presence ventrolateral tubercles, coloration (head upper...
A lotic-breeding salamander Hynobius stejnegeri, formerly called H. yatsui, from western Japan is revised based on genetic and morphological evidence, three species are described: guttatus sp. nov. Chubu-Kinki districts of Honshu Island, tsurugiensis east highland Shikoku kuishiensis other parts Island. Thus, stejnegeri sensu stricto restricted to Kyushu Of these four species, contains two distinct mitochondrial lineages, but this split not reflected in differentiation allozyme (nuclear...
Two new species of lotic-breeding salamanders, Hynobius sematonotos and H. oyamai, are described from Chugoku district northeastern Kyushu district, respectively, western Japan. They members the so-called naevius group phylogenetically close to naevius, katoi, hirosei but divergent them with large genetic distances. These have been treated as lineages, which they morphologically very similar. However, these can be differentiated by several morphological traits. is characterized discriminated...
We found a uniquely colored dicroglossid frog of the genus Occidozyga from western Sarawak, East Malaysia. It is divergent other congeners in morphology and mtDNA sequences. In molecular phylogeny, this species sister lineage to continental O. lima martensii with weak support. The small SVL 16–18 mm males 18–19 females, without dorsolateral fold but transverse wrinkles on dorsum, tips fingers lacking disks toes disks, only first second webbed orange-brown dorsum dark brown band. thus...
Nidiranaokinavana (Boettger, 1895) is a small-sized ranid species belonging to the East Asian genus Nidirana Dubois, 1992. Previous studies have indicated that this was exclusively distributed on Ishigaki and Iriomote islands in southern Ryukyus, as well two extremely small wetland habitats central Taiwan. Such restricted distribution makes it one of most endangered frog both Taiwan Japan. By using molecular, morphological, acoustic analyses, our study reveals significant divergence between...
Rana nigromaculata was found to consume a wide variety of prey organisms in rice fields Kyoto, Japan. Arthropods constituted the bulk its diet both numerically and volumetrically. Frequencies major taxa fluctuated seasonally were significantly correlated with availability estimated by sweeping method. This result suggests that this frog feeds opportunistically depending on encounter rates prey. A significant correlation between individual SVL size frogs larger as they grow. However,...
A molecular phylogenetic survey was conducted using mtDNA sequences of 12S and 16S rRNA, cyt-b genes to examine taxonomic relationships among populations the Pan-Oriental microhylid, Microhyla ornata, from India, Bangladesh, Thailand, Laos, China, Taiwan, Ryukyu Archipelago Japan. Two discrete clades are recognized within this species, one consisting India other encompassing remaining populations. In latter clade, clearly split rest (populations Taiwan continent) with considerable degrees...
Taxonomic status of fanged frogs from the Peninsular Malaysia, previously assigned to Limnonectes kuhlii, is assessed using genetic and morphological approaches. Phylogenetic relationships inferred sequences mitochondrial nuclear genes revealed that Peninsula form a monophyletic group are clearly divergent other species previously, or even now, L. kuhlii Mainland Southeast Asia. In both mtDNA nuDNA phylogeny, Malay clade diverges into two lineages, one north (Larut Hill, Perak, Hulu...

Phylogenetic and taxonomic relationships of the Polypedates leucomystax complex (Amphibia). — Zoologica Scripta , 42 54–70. We investigated phylogenetic estimated history species diversification biogeography in Asian rhacophorid genus focusing on complex, whose members are notoriously difficult to classify. first within using 2005‐bp sequences...
A rhacophorid tree frog from Sumatra that was once identified as Polypedates otilophus (Boulenger, 1893) is sufficiently divergent genetically and morphologically topotypic specimens Borneo to be recognized a distinct species. It herein described P. pseudotilophus sp. nov. The Sumatran frogs can distinguished easily the Bornean population by possession of much more weakly developed supratympanic bony crest, smoother dorsal skin, large, hourglass-shaped dark marking, instead longitudinal...
Microhylidae is a geographically widespread family of anurans. Although several extensive molecular analyses have attempted to elucidate their subfamilial relationships, and correlate these with Mesozoic Cenozoic continental drifts, consensus has not been reached. Further, generic level relationships well investigated in some microhylid subfamilies, therefore affiliations genera are still unclear. To the phylogenetic positions two mysterious Asian genera, Gastrophrynoides Phrynella, better...
Few empirical studies have compared coalescent-based methods to distance-based for delimitation of less divergent species. In this study, we used two (BFD and BPP) barcoding (ABGD jMOTU) delimit closely related species in the Kurixalus odontotarsus group. Phylogenetic analyses revealed that K. group comprises 11 distinct maternal clades with strong support values. Based on genetic morphological evidences, consider diversity was underestimated represent species, which six are unnamed. The...
In order to cope with the complexity and variability of terrestrial environment, amphibians have developed a wide range reproductive parental behaviors. Nest building occurs in some anuran species as care. Species Music frog genus Nidirana are known for their unique courtship behavior mud nesting several congeners. However, evolution these frogs nidification has yet be studied. With phylogenomic phylogeographic analyses based on sampling genus, we find that originated from...
Age in 96 individuals of a tropical frog Rana nigrovittata from Thailand was skeleto-chronologically investigated. Hematoxylinophilic lines interpreted as arrested growth (LAGs) were observed clearly the periosteal bone suggesting that this technique can be used to estimate age frogs Asia. The maximum nine years males and six females, but structure did not differ significantly between sexes. In same class, larger than females.
