  • Non-native flora of the Ulleung island, located in the eastern part of South Korea, was surveyed as 54 taxa with 16 families, 35 genera, 53 species and 1 variety. Considering the geographical distribution aspects of the island, the flora of the island showed more closely related with Korean Peninsular than Japan. Poaceace (28%) and Asteraceae (24%) represents more than 50% of the non-native flora in Ulleung island, meaning that they have an advantage of seed dispersal and adaptation to new environments. Ulleung island is comparatively small island of vulnerable to the attack of invasive alien plants but presently, it has the least number of non-native plants than other areas in South Korea. Therefore, we need to take much interest in prevention and mitigation of non-native plant in the future.

  • This study was conducted to suggest vegetation mat forming methods with native wildflowers, introduced wild flower, grasses and native herb plants which can be used for erosion control of the disturbed slopes. The main results are summarized as follows. In forming the vegetation mat at early stage, foreign grasses, native wild plants shows more effective than the other seed mixture types. But, after 12 weeks, using native wild flowers shows more effective than foreign grasses. Also, the mixture of the native grasses and kentucky bluegrasses (seed mixture type F) are the best in ground coverage among the seed mixtures types. In order to restore slopes more naturally, more diverse plants should be used. The native grasses such as Marrubium incisum Bentham, Lutos comiculatus L. var. japonicus Regel, and Artemisia princeps Pampan seems to be useful to forming the vegetation mat, also it will be more easy if mixing with foreign grasses such as Kentucky bluegrass. The mixture of native grasses and introduced wild flowers are not proper in forming the vegetation mat. Also, pot planting of the native grasses are not proper in forming the vegetation mat.

  • This article presents an overview of the Native Customary Rights to forests and its role in protecting the future of native people of Sarawak, Malaysia. The native people have had a long history and strong relationship with their forests. Existing documents and studies have been critically reviewed and analyzed in order to elaborate the Native Customary Rights which are critical to the native people of this region. To have a better understanding on Native Customary Rights, it is important to answer three related questions: (i) Who is a native of Sarawak, (ii) What is 'custom', and (iii) What is the nature of 'rights'? The roles of Native Customary Rights for economic, political or social reasons, operate through informal rules embedded in the natives' customs and traditions. These rules have never been codified into formal laws because the adat system merely functions to manage the human relations which are tied to culture thus making it difficult to codify the culture into laws. It is evident that there are several issues underlying the development of Native Customary Rights: (i) Native Customary Rights are considered as inferiority to those of the State, (ii) the issue of over-shadowing of traditional laws by the colonial rule and the current statutory laws and, (iii) projects and land schemes involving the Native Land. It is understood that the challenges of promoting Native Customary Rights are daunting task; however, the constitutional laws need to carefully revise to provide a better future for the natives.

  • The restoration techniques of large disturbed land containing native forest resources and soil animals were investigated on the new campus area of Kyushu University in Japan. Important techniques to restore native forest and biodiversity in that area are transplantation of existing large trees, transplantation of the forest soil, transplantation of native tree stools, and the reuse of wood and bamboo chips. The benefits can be obtained by using these methods. Firstly, the native genetic resources that would be discarded as part of the land development can be reused. Secondary, the time taken to become a high growth forest as opposed to the practice of planting saplings or grass seeds can be reduced. At last, the native forest ecosystem containing various under-story vegetations and soil animals can be conserved and regenerated. In addition, big and small ponds were constructed in the biodiversity preservation zone to preserve rare plants, rare animals, and native aquatic animals. And these plants and animals were transplanted and moved to ponds.

  • The taste-active and nutritional components of Thai native, broilers, black-boned, and spent hen chickens were analyzed. The amounts of tasty amino acids especially glutamic acid were the highest in Thai native chicken. The black-boned chicken had the highest arginine content, related to the least amount of consumer satisfaction. Concerning nutritional quality, choline, and taurine were deemed important for brain function. The black-boned chicken showed the highest choline and taurine contents, unlike that of the spent hens. In contrast, broilers presented the highest betaine content, which might be attributed to their lipid metabolism. L-carnitine content was abundant in black-boned and Thai native chickens. Moreover, the amounts of essential amino acids were high in Thai native chicken. In conclusion, black-boned chicken proved to be an excellent nutritional source for health-conscience consumers, whereas the Thai native chickens were flavourful and delicious.

  • Pathogen introductions associated with aquatic invasive species threaten ecosystems and biodiversity worldwide. Bigheaded carps (BHC), including Silver Carp Hypophthalmichthys molitrix, Bighead Carp H. nobilis, and their hybrids, are prolific, invasive pests in central US rivers. However, little is known about pathogen effects on invading BHC or how BHC affect the disease risk profile for native fishes in receiving ecosystems. We therefore conducted, from May 2013-December 2014, a systematic pathogen survey for BHC and native fishes in the Wabash River watershed, Indiana, USA. We found Pseudomonas fluorescens, P. putida, and Salmonella enterica DNA in BHC as well as native fishes, although none of these bacteria were exclusively present in BHC. DNA from other bacterial taxa was detected only in native fishes and Common Carp Cyprinus carpio. No gastrointestinal helminths were detected in BHC, although they were common in most native fishes examined. We also conducted in vitro studies on BHC tissues (skin, gill, fin, and fry) and found high sensitivity to Largemouth Bass virus, viral hemorrhagic septicemia virus, and infectious pancreatic necrosis virus. We conclude that BHC are not heavily burdened by bacteria, viruses and parasites in the invaded study ecosystems, although they do harbor native bacteria and show potential for high sensitivity to endemic viruses.

  • The effective management of endangered animal genetic resources is one of the most important concerns of modern breeding. Evaluation of genetic diversity and relationship of local breeds is an important factor towards the identification of unique and valuable genetic resources. This study aimed to analyze the genetic diversity and population structure of six Korean native chicken breeds (n = 300), which were compared with three imported breeds in Korea (n = 150). For the analysis of genetic diversity, 30 microsatellite markers from FAO/ISAG recommended diversity panel or previously reported microsatellite markers were used. The number of alleles ranged from 2 to 15 per locus, with a mean of 8.13. The average observed heterozygosity within native breeds varied between 0.46 and 0.59. The overall heterozygote deficiency ($F_{IT}$) in native chicken was $0.234{\pm}0.025$. Over 30.7% of $F_{IT}$ was contributed by within-population deficiency ($F_{IS}$). Bayesian clustering analysis, using the STRUCTURE software suggested 9 clusters. This study may provide the background for future studies to identify the genetic uniqueness of the Korean native chicken breeds.

  • This study was conducted to analyze the genetic diversity and relationships that discriminate between Korean native black goat populations (Dangjin, Jangsu, Tongyoung, and Gyeongsang National University strains) and crossbred goats. Monomorphic single nucleotide polymorphisms (SNPs) in each strain were collected, and 133 common SNPs were selected for analysis. These 133 monomorphic SNPs showed differences in the genetic structure of the Korean native black goat and crossbred goats, and results from the principal component analysis (PCA) showed that the two can be clearly separated. Furthermore, analysis of the validation population comprising 70 individuals (Korean native black goats, n = 24; crossbred goats, n = 46) with the reference population showed that Korean native black goat strains and the reference population have the same genetic structure, and the crossbred goats shared only part of the genetic structure with the reference population. The result of the PCA analysis showed that the Korean native black goat strains form one population, whereas the foreign strains form another population which is more widely dispersed than the Korean native black goat strains. Thus, the results from this study can be used as baseline data for the conservation of genetic resources of Korean native black goat communities through utilization of monomorphic SNPs and for the introduction of exotic species for further improvement in genetic diversity. This study can also help reduce unnecessary inbreeding and gene flow between native strains.

  • This study was carried out to analyze the genetic polymorphisms of genomic DNA of blood and meat for conservation of the genetic resources and genetic improvement of Korean Native goat. The genetic identification between Korean Native goat and imported goat was examined using RAPD(random amplified polymorphisms DNAs) analysis with 30 Korean Native goat, 10 hybrid, 10 imported goat. 10 Korean native goat meat and 10 imported goat meat. The results obtained from this study were summarized as follows: 1. Genomic DNA from Korean native goat, hybrid and imported goat could be obtained above about 23kb size using 0.5% agarose gel electrophoresis and the ratio of optical density at 260nm to that at 280nm was between 1.7 and 2.0 using UV spectrophtometer instrument. 2. In the results of the gene identification between Korean Native goat and hybrid, and imported goat using RAPD methods with random primer of 110 kinds, only Korean native goat showed a specific band at about 369bp using a random primer OPO-19 (5'-CAA ACG TCG G-3'), but imported goat and hybrid not showed. 3. Also, in the results of the gene identification between Korean Native goat meat and imported goat meat using RAPD methods with random primer, Korean native goat only showed a specific band at about 369bp using a random primer No. 19(5'-CAA ACG TCG G-3'), but imported goat not showed.
