  • 우리 자생화는 꽃이 화려하진 않지만 소박하고 은은하며 한결같은 모습인 것이 매력이라고 얘기하는 사람들이 많다. 하지만 얼레지 꽃을 보면 여기에 아름다움이 추가되어도 좋을 듯 싶다. 자생화 중에 얼레지만큼 크고 화려한 꽃도 드물지 않나 싶기 때문이다. 4월 중하순경 물이 있는 계곡 주변으로 군락을 이루며 꽃을 피워 대는 얼레지의 환호성을 본 사람이면 누구나 탄성을 지른다. 번식이나 재배가 좀 까다롭긴 하지만 정원이나 분화용으로 시도해 볼만한 종류이다.

  • 하늘나리, 참나리, 섬말나리, 땅나리... 자생화 중 나리류 만큼 꽃이 크고 원색적인 것도 흔치 않다. 나리류는 전 세계적으로 130여종이 있는데 이 중 71종이 아시아에 분포하고 있다. 북반구의 아열대에서 아한대지역까지 집중되어 있으며 해발 2,000~2,500m 정도의 고지대에도 자생한다. 우리나라도 매우 중요한 나리 원산지 중의 한 곳으로 변종을 포함 전국에 15종이 자생하고 있다. 특히 솔나리는 꽃색이 분홍색으로 나리의 주요 육종모본으로 이용되고 있으며, 섬말나리는 울릉도에 분포하며 희소가치가 비교적 큰 식물이다.

  • 이름의 유래는 다양하다. 아래로 향한 꽃잎 모양이 처녀 미니스커트를 닮아 붙였다고 하며, 아래의 가지런한 잎들이 치마모양을 하고 있어 그런 이름을 붙였다는 사람도 있다. 일본 이름을 잘못 번역한 것이라 보고도 있다. 처녀치마는 초본류 중 얼마 안 되는 상록성 식물로써 백합과에 속하며, 고산의 능선 북사면이나 보통 산의 웬만큼 습기가 있는 골짜기에서 흔히 자생한다. 자생지에서 보면 한 겨울 꽁꽁 언 얼음골 옆에서도 녹색을 유지하며 꿋꿋이 견뎌낸다. 연중 상록인 잎 모양도 예쁘지만 봄에 피는 꽃은 매우 아름답다.

  • Avian malaria is one of the most important general blood parasites of poultry in Southeast Asia. Plasmodium (P.) juxtanucleare causes avian malaria in wild and domestic fowl. This study aimed to identify and characterize the Plasmodium species infecting in Thai native fowl. Blood samples were collected for microscopic examination, followed by detection of the Plasmodium cox I gene by using PCR. Five of the 10 sampled fowl had the desired 588 base pair amplicons. Sequence analysis of the five amplicons indicated that the nucleotide and amino acid sequences were homologous to each other and were closely related (100% identity) to a P. juxtanucleare strain isolated in Japan (AB250415). Furthermore, the phylogenetic tree of the cox I gene showed that the P. juxtanucleare in this study were grouped together and clustered with the Japan strain. The presence of P. juxtanucleare described in this study is the first report of P. juxtanucleare in the Thai native fowl of Thailand.

  • Ex-situ catalytic pyrolysis of a Korean native oak tree over microporous zeolites (HZSM-5, HBeta, and HY) was performed by using a fixed bed reactor. The effect of sample to catalyst ratio and reaction temperature was also investigated to optimize production conditions of high quality bio-oil. Among three catalysts, HZSM-5 showed the highest aromatic formation due to its proper pore size and strong acidity. Although HY and HBeta also showed the catalytic activity, they produced larger amounts of coke due to their larger pore size. The smaller ratio of the sample to the catalyst and higher reaction temperature were also required to maximize the yields of aromatic hydrocarbons via the catalytic pyrolysis of oak tree over HZSM-5.

  • Objective: Recently, there has been an increasing interest in conservation of native genetic resources of chicken on a worldwide basis. Most of the native chicken breeds are threatened by extinction or crossing with ecotypes. Methods: Six Saudi native chicken breeds including black naked neck, brown frizzled, black, black barred, brown and gray were used in the current study. The aim of the current study was to evaluate genetic diversity, relationship and population structure of Saudi native chicken breeds based on 20 microsatellite markers. Results: A total of 172 alleles were detected in Saudi native chicken breeds across all 20 microsatellite loci. The mean number of alleles per breed ranged from 4.35 in gray breed to 5.45 in normally feathered black with an average of 8.6 alleles. All breeds were characterized by a high degree of genetic diversity, with the lowest heterozygosity found in the brown breed (72%) and the greatest in the frizzled and black barred populations (78%). Higher estimate of expected heterozygosity (0.68) was found in both black breeds (normal and naked neck) compared to the other chicken populations. All studied breeds showed no inbreeding within breed (negative inbreeding coefficient [$F_{IS}$]). The phylogenetic relationships of chickens were examined using neighbor-joining trees constructed at the level of breeds and individual samples. The neighbor-joining tree constructed at breed level revealed three main clusters, with naked neck and gray breeds in one cluster, and brown and frizzled in the second cluster leaving black barred in a separate one. Conclusion: It could be concluded that the genetic information derived from the current study can be used as a guide for genetic improvement and conservation in further breeding programs. Our findings indicate that the Saudi native chicken populations have a rich genetic diversity and show a high polymorphism.

  • This study was carried out to investigate the ecological characteristic of native Parasenecio firmus population in Korea and China. The survey quadrates were located in the middle of the native P. firmus habitats. According to the field survey, the habitats of P. firmus were classified into same Tilia amurensis community in tree layer. The investigation of native habitat in Korea shows that P. firmus inhabited deciduous forest from with T. amurensis, Acer pictum subsp. mono, Carpinus cordata and Acer pseudosieboldianum, which was similar to vegetation structure of Mt. Laoling in China. The result of the cluster analysis which uses SYN-TAX 2000 program, dissimilarity from 53% level was on a large scale divided at 2 units. The research revealed 96 taxa in total, in which 51 families, 81 genera, 21 varieties, 5 forma, 1 sub-species and 67 species were checked in the flora of the native P. firmus habitats.
