“…D-loop is the predominant regulatory most variable region of mtDNA, used to identify genetically discrete populations, foraging ground, and nesting behavior of turtles, intraspecific variability, and phylogenetic relationship (Nezhad et al 2013). Meanwhile, COI is regarded as valuable molecular marker in turtle species studies (Bhaskar and Mohindra 2018).…”

Abstract. Guntoro J, Wirdateti, Riyanto A. 2020. The very low genetic variability on Aceh Tamiang’s (Indonesia) population of Painted Terrapin (Batagur borneoensis) inferred by cytochrome oxidase I (CO I) and D-loop (control region). Biodiversitas 21: 2514-2520. Populations of Batagur borneoensis have been rapidly decreasing due to the harvesting of adults and eggs for food and the construction of beachfront property causing the loss of nesting areas. By the new Indonesian regulation, since 2018 this turtle listed in the protected animal. Meanwhile, IUCN placed as critically endangered which indicating a high risk of extinction in the wild in the near future (www.iucnredlist.org). We used cytochrome oxidase I (COI) and control region D-loop region to investigate intraspecific variations on Aceh Tamiang’s population of painted terrapin, Batagur borneoensis. DNA material was gathered from saliva collected from 90 juveniles in the reaching facility of Sukacita Lestari Indonesia Foundation which hatched from eggs collected from December 2015 to April 2016 from 30 nests on beach area at Aceh Tamiang. The population showed very low genetic variability (haplotype diversity, Hd = 0.457 based on COI and 0.405 based on D-loop; nucleotide diversity, π = 0.00089 based on COI and 0.00076 based on D-loop). So, we suggested that further study such as more exploration to find new wild populations and genetic study across wild populations should be done to reveal genetic variability and genetic structure which important to decide the conservation strategy. At the time for Aceh Tamiang's population, the ranching conservation program should be maintained at least to keep the successful hatchling from hunters and natural predators both during eggs laying and hatching.

Molecular Identification and Novel Mitochondrial COI Gene Haplotypes of Nesting Kemp’s Ridley Turtles (Lepidochelys kempii) in Rancho Nuevo Sanctuary, Mexico

One hundred new COI sequences of nesting female Kemp’s ridley turtles (Lepidochelys kempii) were obtained in the Rancho Nuevo Sanctuary (RNS). The COI sequences were analyzed and contrasted with others retrieved from BOLD and GenBank with the aim of investigating genetic variability, genetic divergence, and haplotypes of the nesting female population at RNS. Four new COI haplotypes for Kemp’s ridley were described; two are redundant with (LK-RN01) 97 and (LK-COI-01) 17 specimens belonging to the RNS and other localities, respectively. Nucleotide (0.00052) and haplotype (0.303) diversity showed low and conserved COI values The fixation index (FST) between these main redundant haplotypes showed a high degree of differentiation with ~1. Genetic divergence demonstrated clearly two different Kemp’s ridley nesting populations, one from RNS and a second outside Mexico. Phylogenetic COI analysis was useful to differentiate these redundant (LK-COI-01 and RNS LK-RN01) haplotypes and, therefore, these different Kemp’s ridley populations. In addition, phylogenetic COI analysis clearly separates Kemp’s ridley turtles from other sea turtle species, supporting its use as a barcode marker.
