We report on a new species, Zhangixalus melanoleucus sp. nov from the Phou Samsoum Mountain in Xiengkhouang Province, northeastern Laos, based on an integrative taxonomic approach including morphological, molecular and bioacoustic lines of evidence. Morphologically, the new species is distinguished from its congeners by a combination of the followi...

Siamese bat catfish (Oreoglanis siamensis Smith, 1993) has been listed as an endangered species, and its abundance has been severely declining due to habitat degradation and overfishing. To establish an appropriate management strategy, it is crucial to gain information about the distribution of this endangered species. As O. siamensis live under ro...

An integrative systematic analysis recovered a new species of the Cyrtodactylus brevipalmatus group from the uplands of Thong Pha Phum National Park, Kanchanaburi Province in western Thailand. Cyrtodactylus thongphaphumensis sp. nov. is deeply embedded within the brevipalmatus group, bearing an uncorrected pairwise sequence divergence of 7.6–22.3%...

Accurate species identification is critical for highly venomous jellyfish studies particularly for evaluation of their distribution as it is important not only for understanding population dynamics but also predicting risk to locals and tourists. Hazardous jellyfish species have been determined using methods such as comparative morphology and chemi...

The gene numbers and evolutionary rates of birds were assumed to be much lower than those of mammals, which is in sharp contrast to the huge species number and morphological diversity of birds. It is therefore necessary to construct a complete avian genome and analyze its evolution. We constructed a chicken pan-genome from 20 de novo assembled geno...

Thailand is a global biodiversity hotspot, harboring a striking diversity of species and endemism. However, the amphibian diversity in the region is poorly understood. In this study, the frogs Kurixalus odontotarsus and Raorchestes longchuanensis were collected and recorded for the first time in northern Thailand. This determination was based on sp...

Southern Thailand is home to various populations; the Moklen, Moken and Urak Lawoi’ sea nomads and Maniq negrito are the minority, while the southern Thai groups (Buddhist and Muslim) are the majority. Although previous studies have generated forensic STR dataset for major groups, such data of the southern Thai minority have not been included; here...

Slug-eating snakes of the subfamily Pareinae are an insufficiently studied group of snakes specialized in feeding on terrestrial mollusks. Currently Pareinae encompass three genera with 34 species distributed across the Oriental biogeographic region. Despite the recent significant progress in understanding of Pareinae diversity, the subfamily remai...

Herein, we describe a new species of Leptobrachella from Doi Inthanon, Chiang Mai Province, Thailand based on the integration of morphological, acoustic and molecular data. The new species, Leptobrachella murphyi sp. nov., is morphologically di...

Thailand is considered a global biodiversity hotspot that is known to harbour a striking diversity of endemic species. However, several research studies have determined that the level of amphibian diversity in the country has been significantly underestimated. The megophryid genus Leptobrachella Smith, 1925 is currently known to include 89 species...

The taxonomic status of the Thai populations belonging to the Limnonectes kuhlii species complex is controversial, due to phenotypic similarity in the cryptic species complex. Recently, some studies on this group in Thailand have discovered four new species: L. taylori , L. megastomias , L. jarujini and L. isanensis . Even so, the diversity of this...

Cardinal fishes (Apogonidae) belong to the numerically dominating reef fish families. Many species are kept in the aquarium and are popular as small, peaceful, and colorful fish. The taxonomic status of this family remains debatable. Up to the present, there are 366 valid species. However, only 15 species were studied cytogenetically including one...

Background Species domestication is generally characterized by the exploitation of high-impact mutations through processes that involve complex shifting demographics of domesticated species. These include not only inbreeding and artificial selection that may lead to the emergence of evolutionary bottlenecks, but also post-divergence gene flow and i...
