Trace elements were analyzed in the liver of white-fronted geese (Anser albifrons, n=15), mallards (Anas platyrhynchos, n=4) and spot-billed ducks (Anas poecilorhyncha, n=13) found dead in Gimpo, Korea. All mallards and eight spot-billed ducks had embedded lead shot. Embedded shot could be affected elevated trace element concentrations on geese and ducks. Element concentrations of cadmium (Cd), lead (Pb), chromium (Cr), aluminum (Al), copper (Cr), manganese (Mn) and zinc (Zn) differed among species and white-fronted geese without embedded shot had the lowest concentrations for all elements (geomean 0.36, 0.43, 0.07, 1.46, 7.60, 2.61 and 13.5 µg/g dw, respectively). Cadmium in four (3.27–7.77 µg/g dw) of 32 individuals and Pb in eight (5.07–9.72 µg/g dw) of 32 individuals exceeded a tentative threshold effect level of Cd (>3.0 µg/g dw) and Pb (>5.0 µg/g dw) for birds; all geese and ducks for Cr (0.07–0.43 µg/g dw) were within the background level (<4.0 µg/g dw). All trace element concentrations were much greater in waterfowl species with embedded shot than without shot. Essential trace elements such as Cr, Al (geomean 1.46–37.3 µg/g dw), Cu (7.60–57.1 µg/g dw), Mn (2.61–27.6 µg/g dw) and Zn (13.5–176 µg/g dw) were within the normal range and were probably maintained by normal homeostatic mechanisms. © 2016 Elsevier Inc.

Cheorwon-gun is an important wintering area for the red-crowned crane (Grus japonensis). Although eco-tourism has been recently proposed as a means to stimulate the local economy, it may have adverse effects on the crane. We believe a science-based conservation plan is needed to mitigate these negative effects. To this end, our study had three objectives: (1) to analyze the red-crowned crane habitat and its suitability in Cheorwon-gun, using field surveys and habitat modeling; (2) to check the feasibility of alternative habitat patches across demilitarized zones (DMZs); and (3) to propose a conceptual diagram that minimizes habitat loss during development activities. We aim to quantify habitat suitability, the farmland area needed to support existing crane populations in wintertime, disturbance caused by human activities, and vehicular spatial patterns. These data could be used in spatial planning. The framework of this study and the process of making a conceptual diagram could be applied to other areas where there is a conflict between development and habitat conservation. © 2016 by the authors.

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 was conducted to determine the distribution and breeding status of the black-faced spoonbill (Platalea minor) for conservation and management purposes in South Korea. Breeding and stopover sites of the black-faced spoonbill were mainly in uninhibited islets off the west coast of the Korean Peninsula; wintering sites were observed on Jeju Island. Between April and July 2013, we observed 638 black-faced spoonbill nests along the west coast of the Korean Peninsula. Most of the nests were observed in the Gyeonggi Bay area, on Kujido Islet, Bido Islet, Namdong retaining basin, Youdo Islet, Suhaam Islet, Seomando Islet, and Maedo Islet, which were major breeding sites for these birds. It is essential to understand the distribution, breeding status, ecology, and habitat patterns of the black-faced spoonbill, based on existing data, for the conservation and management of this species. Long-term ecological research on the population dynamics of the black-faced spoonbill is needed to implement a successful conservation strategy. © 2016 Korean Forest Society

This study was conducted to clarity the distribution and breeding status of Chinese egret Egretta eulophotes for conservation and management in South Korea. The known habitat of the birds in South Korea is confined to 10 sites. All the breeding sites are uninhibited offshore islets in the Yellow Sea, South Korea. Major breeding sites are Napdaekiseom, Hwangseodo, Chilsando, Seomando and Mokdo Islets. Most of the nests are located in dense stands of arrow bamboo Pseudosasa japónica and baby brier Rosa multiflora. The vegetation of the offshore islets with breeding sites should be maintained and managed to help the birds breed successfully. Human disturbance by photography and egg collection should be prohibited in breeding islands. An action plan based on long-term ecological research should be prepared to aid the conservation of the birds and their habitats. © Medwell Journals, 2013.

Korea is an important geographical location for wintering dabbling ducks. In order to investigate their relationships, 92 ducks from ten breeds were sampled from nine different geographical areas in Korea. Of these, 38 samples are represented as Mallard (Anas platyrhynchos), Spot-billed (Anas poecilorhyncha zonorhyncha) and domestic (Anas platyrhynchos domesticus) ducks. They are very closely related to commercial duck breeds. The partial (746 and 749 bp) mitochondrial DNA (mtDNA) COI (Cytochrome Oxidase I) gene sequences were obtained and 126 SNPs were identified, which belong to 23 haplotypes. Eighty five Anas and ten Aix genus have been used for phylogenetic analysis. Based on the neighbor-joining (NJ) method, duck species used in this study can be well differentiated, except for the three duck breeds, Mallard, Spot-billed and domestic ducks, where most of the individuals belong to haplotype 12. The highest K2P distance, 0.31, was observed in Spot-billed ducks, with a range of 0.07-10.96 between the species. However, there was no correlation between geographic distance (km) and K2P distance (%) between the species. Based on our results, duck species can be discriminated with COI sequences, except for the three closely related breeds, and this can be effectively used for an appropriate conservation program for the wild duck breeds in Korea. © 2012, Japan Poultry Science Association.

For the first time in Korea, stable isotope ratio mass spectroscopic analysis method was introduced as an alternative method to track the movement of the migratory birds. Hydrogen isotope ratio (δ2H) and oxygen isotope ratio (δ18O) of the feather samples were collected from northern pintail, which were captured in Junam Wetland Park and were measured using a continuous flow-isotope ratio mass spectrometer. The δ2H values of all feathers show a bimodal frequency distribution with a wide range of δ2H values (-30 ‰ to -120 ‰), while the range δ18O values was relatively very small (ca. 6-18 ‰). The difference between the two modes in the frequency distribution of δ2H values for male was more than that for female. Although the two-dimensional plot of δ2H versus δ18O can provide the information on the breeding ground of the migratory wild birds. The northern pintails captured in Junam Wetland Park have more than two geographical origins.

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.

In order to analyze the home range of feral cats residing in the surroundings of rural and suburban areas, we collected coordination information data from five feral cats. As a result of such research, 100% MCP was defined as minimum 31,500 and maximum 351,900, and 95% KR was defined as minimum 9,400 and maximum 502,800, 75% KR was defined as minimum 3,600 and maximum 126,900, and 50% MCP was defined as minimum 1,800 and maximum 51,700. The home range of feral cats was also analyzed during daytime and nighttime, and all five individuals showed a wider home range during the nighttime than daytime. The analysis of gender shows that the average home range of female feral cats is larger than the average of males. Meanwhile, the results of information data with wide-open areas such as farm land and terrace land on the river showed that the analyzed value was increased generally, and showed variable values depending on the gender and size of each individual feral cat. © 2013 Korean Biodiversity Information Facility.

Trace elements were analyzed in the liver of white-fronted geese (Anser albifrons, n=15), mallards (Anas platyrhynchos, n=4) and spot-billed ducks (Anas poecilorhyncha, n=13) found dead in Gimpo, Korea. All mallards and eight spot-billed ducks had embedded lead shot. Embedded shot could be affected elevated trace element concentrations on geese and ducks. Element concentrations of cadmium (Cd), lead (Pb), chromium (Cr), aluminum (Al), copper (Cr), manganese (Mn) and zinc (Zn) differed among species and white-fronted geese without embedded shot had the lowest concentrations for all elements (geomean 0.36, 0.43, 0.07, 1.46, 7.60, 2.61 and 13.5g/g dw, respectively). Cadmium in four (3.27-7.77g/g dw) of 32 individuals and Pb in eight (5.07-9.72g/g dw) of 32 individuals exceeded a tentative threshold effect level of Cd (>3.0g/g dw) and Pb (>5.0g/g dw) for birds; all geese and ducks for Cr (0.07-0.43g/g dw) were within the background level (<4.0g/g dw). All trace element concentrations were much greater in waterfowl species with embedded shot than without shot. Essential trace elements such as Cr, Al (geomean 1.46-37.3g/g dw), Cu (7.60-57.1g/g dw), Mn (2.61-27.6g/g dw) and Zn (13.5-176g/g dw) were within the normal range and were probably maintained by normal homeostatic mechanisms.
