Amphibian survey of Ko Pha-gnan in Surat Thani Province, Thailand.

Insular amphibian species are often overlooked, rendering them vulnerable to habitat encroachment and other anthropogenic threats. The aim of this study was to compile a comprehensive list of amphibian species on Ko Pha-ngan in Surat Thani Province, Thailand. Data were collected via transect surveys and drift line fence traps in three different habitat types from February 2021 to September 2023.

A description of the second species of the genus Platybolium Blair, 1938 (Coleoptera: Tenebrionidae) collected from a nest of Pheidole singaporensis Özdikmen, 2010 (Hymenoptera: Formicidae) in Thailand.

Platybolium watanai sp. nov., the second species of the genus, is described from Thailand, with illustrations of the diagnostic characters, including the defensive glands and the cuticular structures of females.

Complete mitochondrial genomes of the Southeast Asian freshwater pufferfishes, (Roberts, 1998) and (Sontirat and Soonthornsatit, 1985) (Tetraodontiformes: Tetraodontidae) and an insight into the taxonomic status of species.

The complete mitochondrial genomes of the Southeast Asian freshwater pufferfishes, and , were reconstructed using the MGISEQ platform. The genomes were 16,448 bp and 16,449 bp in length, each made up of 37 mitochondrial genes (13 CDSs, 22 tRNAs, and two rRNAs) and putative control region. It is suggested that an accumulation of complete mitochondrial genome sequences can contribute to resolve the taxonomic status of species.

Population Genetic and Social Structure Survey of in Thailand.

Fire ants have long been known to be a major pest and have recently attracted renewed widespread attention due to the invasion of species, especially , into many countries in Asia and Australia. Here, we surveyed fire ant specimens in Thailand with the aims of studying their colony biology and population structure. We sampled 38 colonies distributed in agricultural and urban areas throughout Thailand for species identification and found that all were .

Seven new species occurring on termites are added to - , , , , , and , based on morphological and molecular phylogenetic evidence. possesses orange to reddish-brown immersed perithecia on cylindrical to clavate stromata. , and have pseudo-immersed perithecia while , and all possess superficial perithecia, reminiscent of and .

Phylogenetic Diversity and Single-Cell Genome Analysis of "Melainabacteria", a Non-Photosynthetic Cyanobacterial Group, in the Termite Gut.

Termite guts harbor diverse yet-uncultured bacteria, including a non-photosynthetic cyanobacterial group, the class "Melainabacteria". We herein reported the phylogenetic diversity of "Melainabacteria" in the guts of diverse termites and conducted a single-cell genome analysis of a melainabacterium obtained from the gut of the termite Termes propinquus. We performed amplicon sequencing of 16S rRNA genes from the guts of 60 termite and eight cockroach species, and detected melainabacterial sequences in 48 out of the 68 insect species, albeit with low abundances (0.

CO2 efflux from subterranean nests of ant communities in a seasonal tropical forest, Thailand.

Many ant species construct subterranean nests. The presence of their nests may explain soil respiration "hot spots", an important factor in the high CO2 efflux from tropical forests. However, no studies have directly measured CO2 efflux from ant nests.
