The complete mitochondrial genome of the sand bubbler crab Shen 1932 (Decapoda: Dotillidae) and its phylogenetic analysis.

The sand bubbler crab, Shen, 1932 (Arthropoda: Malacostraca: Decapoda: Thoracotremata: Dotillidae), is commonly found along tropical and subtropical sandy shores of China, Korea, and Taiwan. Ecologically, it plays an important role in the productivity of sandy shores through their feeding and burrowing activities. In this study, the first complete mitochondrial genome (mitogenome) of was analyzed using next-generation sequencer.

Development of molecular identification methods for and , and their hybrids.

Background: As hybridization can reduce biodiversity or cause extinction, it is important to identify both purebred parental species and their hybrids prior to conserving them. The Suwon tree frog, is an endangered wildlife species in Korea that shares its habitat and often hybridizes with the Japanese tree frog, . In particular, , , and their hybrids often have abnormal ovaries and gonads, which are known causes that could threaten their existence.

The complete mitochondrial genome of the bait worm, (Annelida; Polychaeta; Eunicida; Eunicidae).

The complete mitochondrial genome of Lavesque, Daffe, Bonifácio & Hutchings, 2017, was 15,891 bp in length with a GC content of 41%, comprising 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. The maximum-likelihood tree showed the closest relationship between and .

Characterization of the complete mitogenome of the endangered freshwater fish Gobiobotia naktongensis from the Geum River in South Korea: evidence of stream connection with the Paleo-Huanghe.

Background: The freshwater fish Gobiobotia naktongensis (Teleostei, Cypriniformes, and Gobionidae) is an endangered class I species whose population size has been greatly reduced.

Objective: To successfully protect and restore the highly endangered freshwater fish G. naktongensis from the Geum River in South Korea.
