  • The purpose of this study was to understand the geographical and environmental distribution of wild animals in Baekdudaegan region using field survey and GIS data. Crucial factors were selected and analyzed to understand the distributional characteristics of wild animals (7 species in 6 families) and rare endemic plants (14 species in 11 families). These crucial factors include stand factors (forest type, DBH class, and crown density), soil factors (bed rock, soil texture, and organic matter), geographical factors (elevation, slope, aspect) and climatic factors (temperature, rain fall, humidity). Finally, 10 factors were selected by statistical analysis and categorized for analyzing geographical and environmental features. Four families such as Muridae, Sciuridae, Suidae and Talpidea in wild animal showed the similar habitat characteristics with the 10 factors.

  • The Illam district, situated in the extreme North Eastern part (Latitude 26.58N and 87.58E Longitude) of Nepal, is a hot spot for floral diversity. The study of wild edible plants of this region was an attempt to highlight the types of wild flowering plants found there and mode of use by the people of the Illam hills. In this respect, a survey of natural resources of some of the representative regions of the district was undertaken and more than 74 major varieties of plant species were found to be used frequently by the people of the hills. The rich diversity occurring in Dioscoriaceae, Moraceae, Rosaceae, Myrtaceae, Poaceae, Urticaceae and Arecaceae provided the wild angiospermic species commonly used by the people of the hills.

  • To provide basic information for wildlife management, we investigated the distribution and ecology of wild mice in Mt. Keumwon recreational forests. The trapped wild mice were a total of 4 species such as Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens. A total of 79 individuals from four species were trapped. Number of Eothenomys regulus was the highest as 41 individuals followed by Apodemus speciosus peninsulae of 31 individuals, Apodemus agarius of 4 individuals, and Crocidura suaveolens of 4 individuals. Depending on forest type, 51 individuals were captured in broad-leaved forests, whereas 28 individuals were captured in coniferous forests. Average weight of the trapped Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens was 37.13 g, 36.29 g, 31.25 g, and 15 g, respectively. Among the trapped wild mice, vole which has the largest head and ears were Eothenomys regulus and vole which has the longest tail was Apodemus speciosus peninsulae and Apodemus agarius (p<0.5). This study might be valuable to control and predict some damages related to wild mice in Mt. Keumwon for protecting forest trees.

  • Genetic improvement of the cultivated soybean [Glycine max (L.) Merr] may be possible through hybridization with its wild progenitor, G. soja Sieb. & Zucc. Interspecific cross between G. max (Hwangkeumkong) and G. soja (IT.182932) was made in the summer of 1997. In F$_2$ the percentage of plant height, nodes per plant, and pods per plant were high but gradually reduced from F$_2$ to F$_4$. In contrast pod length, seeds per pod, and 100-seeds weight were increased gradually through generations advanced. Wild variation as evident in F$_2$ in plant height, number of branches, pods per plant, and 100-seeds weight. Twenty six percent of the F$_2$, 44 % of the F$_3$ and 60% of the F$_4$ segregants showed more G. max traits. The combination of useful traits from both species is possible through interspecific hybridization. The characters that could be transferred from wild species to cultivated species are more pod number, better capacity, and resistance to disease and insects. The interspecific derivatives offer scope for selection for high grain yield. Therefore, introducing genes from G. soja to G. max could be contribute to greater genetic diversity of future cultivars. And semicultivated soybean had some desired characteristics including tolerance to adverse environments and multi-seed characters. It means the infusing of semicultivated germplasm to the cultivated soybean could increase number of seeds and pods per plant significantly, and consequently could enhance selecting potential on yield.

  • The soil pH favored by Korean wild plants is 5.33~7.20, while naturalized invader species prefer soils of pH 3.95~6.48. The germination rate of Zoysia japonica was inhibited sharply, up to 60%, in extracts of naturalized plants of concentrations over 50%. Erigeron canadensis extract most strongly inhibited germination, while the Korean wild species, Cassia mimosoides var. nomame increased germination rates in concentrations of 30% and 50%. The seedling growth of Zoysia japonica in extracts of Korean wild species and naturalized species did not show differences, but was inhibited strongly, up to 60%, in the extract of Cassia mimosoides var. nomame concentration of over 15%. Analysis of the extract from Cassia mimosoides var. nomame identified procatechuic acid, $\rho$-hydroquinone, $\rho$-coumaric acid and ferulic acid at 254nm; and vanillic acid, hydroquinone, benzoic acid and cinnamic acid were discovered at 284nm. The seed germination and seedling growth of Zoysia japonica were investigated under different concentrations of phenolic compounds. Ferulic acid and vanillic acid were associated with an increased germination rate, while $\rho$-coumaric acid appeared to inhibit seedling growth.

  • This study was conducted to maintain the productivity of forest production and byproducts production of natural forest. Distribution of wild edible herb species and correlations between wild edible herb species and forest-type, and site factors were surveyed on national forest in Changjeon-ni, Pyungchang-gun, Kang-won-do. Ligularia fischeri was distributed mainly on cutting sites or meadow or Quercus mongolica forest, Pimpinella brachycarpa did on broadleaved mixed forest, and Synurus deltoides did cutting sites or meadow. On conifer plantations major wild edible herb species were not distributed. Pimpinella brachycarpa and Ligularia fischera were distributed mainly on the site of wet soil-moisture condition, Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were distributed randomly. The distribution of Ligularia fischeri and Pimpinella brachycarpa were significantly different between slope directions, but those of Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were not significant. Ligularia fischeri and Pimpinella brachycarpa were distributed more frequently in north directed slope than the other. Highly positive correlations were proved Ligularia fischeri and Pimpinella brachycarpa, Aconitum jaluense and Veratrum patulum; Pimpinella brachycarpa and Smilacina japonica, Aconitum jaluense and Veratrum patulum.

  • The number of wild animal species is gradually decreasing due to poaching, hunting and habitat loss. While several endangered animal species have been successfully preserved at the zoo, assisted reproductive technology (ART) must be applied to restore wild animals. In the case of critically endangered animals, somatic cell cloning is considered the most appropriate method of ART. Somatic cell cloning can be beneficial for the reproduction of endangered species with limited female populations. However, gene and cell banks, and understanding of reproductive physiology and optimization of ART for wild animals are urgently required for further activation of artificial reproduction of endangered species, which enlarges its application and maintains biodiversity. Care should also be taken to consider ethical and legal issues associated with somatic cell cloning for conservation of endangered animals.

  • Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates including 67 isolates obtained from symptomatic leaves and ears of wheat, barley, and wild grasses from two wheat growing region in Iran as well as 206 isolates from our collection from other regions in Iran which were isolated in our previous studies. Mating type genes phylogeny was successfully used to determine the species identity and relationships among isolates within the Phaeosphaeria spp. complex. In this study, we reported seven new host records for Phaeosphaeria species and the Phaeosphaeria avenaria f. sp. tritici 3 group was first reported from Iran in this study. Mating type distribution among Phaeosphaeria species was determined. Both mating types were present in all sampling regions from Iran. We observed skewed distribution of mating types in one region (Kohgiluyeh va Boyer-Ahmad) and equal distribution in the other region (Bushehr). However, when considering our entire dataset of 273 Iranian Phaeosphaeria isolates, the ratio of mating types was not deviated significantly from 1:1 suggesting possibilities for isolates of opposite mating type to interact and reproduce sexually, although the sexual cycle may infrequently occur in some regions especially when the climatic conditions are unfavorable for teleomorph development.
