Recently, the consumption of duck meat has increased; therefore, we need to reveal the origin and gene flow of domestic ducks in Korea. In order to discriminate between duck species, d-loop variations in mitochondrial DNA (mtDNA) have been investigated. In this study, 45 individuals from seven species of wild and domestic ducks in Korea were considered for the d-loop region sequences. With the participation of all the sequences, a phylogenetic neighbor-joining tree was constructed to differentiate between the wild and domestic duck species. In consideration of these sequences, a total 66 haplotypes were obtained (indel included) with an average haplotype of 76.9 %, and a haplotype and nucleotide diversity of 0.91 and 0.01, respectively. Also, an estimation of the sequence divergence within and between species was measured in 0.045 and 0.013-0.095, respectively. Meanwhile, the lowest distances of 0.024, 0.013 and 0.018 were observed in three species, including the Mallard, Spot-billed and domestic duck, respectively, which have relatively close genetic relationships. All haplotypes were used for the median-joining network analysis to differentiate all duck species, while three duck species were closely related. Moreover, 26 indel polymorphisms were identified which could be used for the discrimination among the duck species. Based on our results, duck species were effectively discriminated in a d-loop region, which could then be used for an appropriate genetic conservation program for the wild duck and domestic duck breeds in Korea. © 2014 Springer Science+Business Media.

This study conducted the total six times of survey at Gangjin Bay in Gyeongsangnamdo from June in 2012 to March in 2013. The number of waterfowl observed during the survey period was the total of 48 species and 17,799 individuals for the maximum number of individuals. The most dominant species was Aythya marila (37.0%), followed by Aythya ferina (28.8%). The monthly appearance species (appearance rate of 100%) was recorded as 7 species including Anas poecilorhyncha, Ardea cinerea, Egretta alba modesta, Egretta garzetta, Falco tinnunculus, Larus crassirostris, and Larus ridibundus. The legally protected species was found to be total 8 species including Endangered Species I (2 species), II (5 species), and natural monument (6 species). The mudflat grade for birds showed high protective value with II grade, which was the same grade as at Gangjin Bay and Muan Bay in Jeollanamdo. Therefore, it is suggested to prepare for the plan to protect and manage waterfowls and ducks at Gangjin Bay areas during the wintering season. © 2013 Korean Biodiversity Information Facility.

Eremias argus, which specifically inhabits riverside or coastal sand dune, is an endangered species designated by the Ministry of Environment of Korea because it has been drastically decreasing due to the destruction of habitat and the human activities. Therefore, it is required to prepare a countermeasure for the strategic and systematic solutions for the conservation of the E. argus. This study analyzed mtDNA cytochrome oxidase subunit I (COI) gene of E. argus inhabiting Yoobu-do island and Sohwang sand dune. This study aims to provide fundamental genetic information through phylogeographical analysis between two regions. Of 11 individuals of E. argus used in the analysis, the total 652∼656 bp of mtDNA COI genes for 3 individuals of Takydromus wolteri as 'out group' were analyzed. Intraspecific genetic distance for E. argus was shown to be the same result of 0.000. As for T. wolteri, it was 0.005, showing very similar result. T. wolteri inhabiting Gapcheon stream in Daejeon metropolitan city was found to be the highest intraspecific genetic distance (0.008). The NJ tree of E. argus and T. wolteri indicated there was almost no genetic difference between habitat for E. argus. For T. wolteri, however, there was slight difference between the individuals inhabiting Yoobu-do island and those inhabiting Gapcheon stream in Daejeon metropolitan city. Therefore, it is necessary to prepare conservation strategies to increase genetic diversity of E. argus in Yoobu-do island in the future because it is highly presumed that the population of E. argus in Yoobu-do island have been flown from nearby coastal sand dune. © 2013 Korean Biodiversity Information Facility.

This study was conducted to examine the benthic invertebrate fauna inhabiting in the subtidal zone in and around the islets of Namuseom and Bukhyeongjeseom off the coast of Busan by SCUBA diving in September 2013. As a consequence, it was confirmed that a total of 6 phyla, 14 classes, 20 orders, 46 families, and 73 species of zoobenthos inhabit in and around those islets. The total number of species surveyed by taxon during the study is 22 species of Arthropoda (30%), 20 species of Mollusca (27%), 15 species of Cnidaria (21%), 10 species of Echinodermata (14%), four species of Poridera (5%), and two species of Chordata.

The biodiversity of benthic invertebrates in the intertidal and subtidal regions of Gapado, Beomseom, and Munseom islets was surveyed twice in May and September 2013 to study the state of biodiversity in Seogwipo, Jeju Island. As a result, a total of 77 species, 46 families, 25 orders, 14 classes, and nine phyla of benthic invertebrates were found. The species which were found, by taxon, consisted of the following: 26 species of Cnidaria (34%), 24 species of Mollusca (31%), seven species of Chordata (9%), six species of Arthropoda (8%), six species of Porifera (8%), five species of Echinodermata (7%), one species of Bryozoa (1%), one species of Annelida (1%), and one species of Ctenophora (1%).
