“…For example, microsatellite loci of a wild population of Oriental white stork Ciconia boyciana (Swinhoe, 1873) included two to eight alleles (Huang & Zhou, 2011), and two to three alleles in an ex situ population of Japanese crested ibis Nipponia nippon (Temminck, 1835) (Urano et al , 2013). As for mitochondrial DNA, six haplotypes of control region in mitochondrial DNA were found in Okinawa rail Gallirallus okinawae (Yamashina & Mano, 1981), an endemic species on Okinawa Island (1207 km 2 ) (Ozaki et al , 2010), and 23 haplotypes in Oriental white stork (Onuma et al , 2011). The limited habitat of the Bali myna, restricted as it is to the northern area of the island of Bali since first description (Stresemann, 1912), and the population decline of the bird as a result of habitat destruction and illegal poaching (BirdLife international, 2016), were assumed to be the cause of low genetic variation in the wild species.…”

The aim of this study was to develop polymorphic DNA markers for Bali myna Leucopsar rothschildi. The mitochondrial cytochrome c oxidase subunit II (COII) gene was sequenced, and polymorphic microsatellite loci were searched using Next Generation Sequencing. Three haplotypes of mitochondrial COII gene were found in a Japanese population of Bali myna in human care. Eight polymorphic microsatellite DNA markers were also identified. In a sample group of 22 individuals, numbers of alleles and expected heterozygosities of the eight microsatellite loci ranged from two to three and 0Á241 to 0Á609, respectively. These results suggested that the genetic variation of this species might be low, similar to that of other threatened bird species.

Take one step backward to move forward: Assessment of genetic diversity and population structure of captive Asian woolly-necked storks (Ciconia episcopus)

The fragmentation of habitats and hunting have impacted the Asian woolly-necked stork (Ciconia episcopus), leading to a serious risk of extinction in Thailand. Programs of active captive breeding, together with careful genetic monitoring, can play an important role in facilitating the creation of source populations with genetic variability to aid the recovery of endangered species. Here, the genetic diversity and population structure of 86 Asian woolly-necked storks from three captive breeding programs [Khao Kheow Open Zoo (KKOZ) comprising 68 individuals, Nakhon Ratchasima Zoo (NRZ) comprising 16 individuals, and Dusit Zoo (DSZ) comprising 2 individuals] were analyzed using 13 microsatellite loci, to aid effective conservation management. Inbreeding and an extremely low effective population size (Ne) were found in the KKOZ population, suggesting that deleterious genetic issues had resulted from multiple generations held in captivity. By contrast, a recent demographic bottleneck was observed in the population at NRZ, where the ratio of Ne to abundance (N) was greater than 1. Clustering analysis also showed that one subdivision of the KKOZ population shared allelic variability with the NRZ population. This suggests that genetic drift, with a possible recent and mixed origin, occurred in the initial NRZ population, indicating historical transfer between captivities. These captive stork populations require improved genetic variability and a greater population size, which could be achieved by choosing low-related individuals for future transfers to increase the adaptive potential of reintroduced populations. Forward-in-time simulations such as those described herein constitute the first step in establishing an appropriate source population using a scientifically managed perspective for an in situ and ex situ conservation program in Thailand.
