“…In the study, two samples each from the west coast of Thailand and east coast of Peninsular Malaysia were analyzed. The final partitioned nucleotide alignment consists of 14,098 base pairs, and formed a maximally-supported monophyletic group within the Uranoscopus clade, although clustering between samples collected from Malaysia was not strongly supported 55 . Herein, the mtDNA CO1 and nuDNA RAG1 genes were sequenced to examine the genetic diversity, phylogenetics and demography of U. cognatus within the IWP, with the inclusion of CO1 sequences retrieved from Indonesia (INDO) and Australia (AUS).…”

Benthic species, though ecologically important, are vulnerable to genetic loss and population size reduction due to impacts from fishing trawls. An assessment of genetic diversity and population structure is therefore needed to assist in a resource management program. To address this issue, the two-spined yellowtail stargazer (Uranoscopus cognatus) was collected within selected locations in the Indo-West Pacific (IWP). The partial mitochondrial DNA cytochrome c oxidase subunit 1 and the nuclear DNA recombination activating gene 1 were sequenced. Genetic diversity analyses revealed that the populations were moderately to highly diversified (haplotype diversity, H = 0.490–0.900, nucleotide diversity, π = 0.0010–0.0034) except sampling station (ST) 1 and 14. The low diversity level, however was apparent only in the matrilineal marker (H = 0.118–0.216; π = 0.0004–0.0008), possibly due to stochastic factors or anthropogenic stressors. Population structure analyses revealed a retention of ancestral polymorphism that was likely due to incomplete lineage sorting in U. cognatus, and prolonged vicariance by the Indo-Pacific Barrier has partitioned them into separate stock units. Population segregation was also shown by the phenotypic divergence in allopatric populations, regarding the premaxillary protrusion, which is possibly associated with the mechanism for upper jaw movement in biomechanical feeding approaches. The moderate genetic diversity estimated for each region, in addition to past population expansion events, indicated that U. cognatus within the IWP was still healthy and abundant (except in ST1 and 14), and two stock units were identified to be subjected to a specific resource management program.

“…To date, only a single genetic study describing the whole mitogenome of U. cognatus is available 55 , limiting our knowledge on the population genetic diversity of this bioresource. In the study, two samples each from the west coast of Thailand and east coast of Peninsular Malaysia were analyzed.…”
