조팝나무속 식물은 주로 아시아에 많이 분포하는 목본으로 생태 및 약용으로 중요하다. 이 속내 16종, 29집단에 대해 RAPD (random amplified polymorphic DNA) 마커로 이들 집단에 대한 유전적 변이와 집단구조를 조사 하였다. 이들 집단은 작고 격리되어 있어 낮은 유전적 다형성을 나타내었다. 전체 유전적 다양도는 종 수준에서 0.117이였다. 국지적 분포를 보이는 종(S. chartacea)은 광범위하게 분포하는 종에 비해 유전자 좌위당 대립유전자의 수는 적었고(평균 1.240:1.297), 다형성을 나타내는 유전자 좌위 %(24.0:29.7), 낮은 다형성(0.092 vs. 0.121)을 나타내었다. 종내 다양성의 비율($H_{POP}/H_{SP}$)은 전체 변이중 87.8%가 종간에 있었고 전체 변이의 12.2%는 종내에 있었다. 계통도에서 세 그룹으로 나타났다. 한 분지군은 조팝나무, 가는잎조팝나무, 인가목조팝나무, 긴조팝나무, 공조팝나무이었다. 또한 분지군은 산조팝나무, 아구장나무, 떡잎조팝나무, 당조팝나무였다. 나머지 분지군은 7종을 포함하고 있었다.

The needled leaves of three conifer species were collected in Mt. Taehwa during different seasons of the year. Total 59 isolates and 19 species of endophytic fungi were isolated from the leaves and identified using morphological and molecular characteristics. As a result, Shannon index was different in its host plant; Larix kaempferi had a highest value of species diversity. According to the sampling season, 9 species of 19 species were isolated during fall season. The results suggest that the existing of host plant and sampling season are major factors of distribution of endophytic fungi.

In our ongoing efforts to explore the species diversity of the harpacticoid fauna in Korea, we present findings on four newly identified species from family Tegastidae Sars, 1904. Although this family is frequently encountered in phytal communities, the diversity of tegastid copepod species within Korean waters largely remains to be elucidated. Drawing from our collections of tegastid harpacticoids from Chuja-do and Geomun-do Islands, we provide morphological descriptions for Tegastes lobus sp. nov., T. tresetosus sp. nov., T. pilosus sp. nov., and Syngastes acutus sp. nov., and propose their taxonomic relationships in relation to other species within the genus. Finally, we update the list of tegastid harpacticoids found in Korea and provide a key for identifying the six confirmed species from this region.

Mt. Taebaeksan extends from Gangwon-do Province (Taebaek-si, Youngwon-gu, and Jeongseon-gun) to Gyeongsangbuk-do Province (Bongwha-gun), South Korea. Indigenous fungi present in the park were investigated between 2019 and 2022. All collected specimens were identified to the species level based on their morphological characteristics and molecular phylogenetic analysis using sequences from the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA. Among them, 17 species-Cyanosporus bifarius, Dacryobolus angiospermarum, Entoloma sericeum, Flammulina rossica, Fuscopostia leucomallella, Homophron helvolescens, Hygrophorus queletii, Hymenochaete huangshanensis, Inocybe albodiscoides, Lactarius fulvihirtipes, Lepiota ignivolvata, Physisporinus eminens, Ramaria gracilis, Russula albolutea, Russula cremicolor, Stropharia lignicola, and Tengioboletus subglutinosus-were newly recorded macromycota in Korea.

The early vegetational recovery and species diversity were investigaed in burned pine forest of Mt. Todoksn from 1986 to 1990. The changes of vegetation in the burned site occurred Miscanthus→Miscanthus-Lespedeza→Lespedeza community. The biological spectra based on SD(%) and SP(%) of the burned site were similar to the unburned site with H---e type. The degree of succession(DS) was gradually increased with succession in burned site. The species diversity index(H') and evenness index(e) were declining successional trend, nut dominance index(C) inclining successional trend in the burned site. The domiance-diversity curves of the burned site showed gradual decrease in diversity and evenness, and then slopes of them were progressively steep in early successional stage.

Microorganism are centIal core to biosphere sm1ainablity and biogeochemical cycles on this earth. Most of food, medical and pabamceutical new materials through biotechnology are derived from many kinds of microorganisms. Microorganisms are important resources of biotechnology. Beside these, micorbial diversity is key to explore the frontiers of knowledge about the strategies and limits of life. Through the micorotganisms, we can monitor the environmental changes and conditions. Moreover, the microorganismsms play a role in conservation and restoration of higher plants and animals. And we can get a lot of ecological, evolutionary knowledges from microbial models. In spite of these importances, the microbial diversity is not properly evaluted because of their unculturablity. Only 0.001 - 3 % of total bacteria in natural habitats are cultumble and the rest are viable but uncultumble. Only 3,100 species are listed up in the Bergey's Manual. Considering the symbisis and estimated numbers of insect are more than 800,000, the symbiotic microorganisms are about 1,000,000 species. Recently, by using the genetic and molecular technics, the microbial diversity is now unveiled. In this symposium, the genetic, species and ecological diversity will be given. given.

A study on the dominance-diversity of forest vegetation in Mt. Seolag was conducted from May 1981 to Aug. 1983. Based on the field data, the dominance-diversity curves were for 16 sites including slopes and vallies. The curves are grouped in two types, lognormal distribution at the sites of mature vegetation and geometric series at the disturbed or rocky sites. It seems that the curves express the nature of their ecocline, by the hypotheses of some investigators, i.e. Random Niche hypothesis, Niche Pre-emption hypothesis, Lognormal distribution and Logarithmic series. The dominance concentration among the southern, northern and western slope, H'=1.282 at southern slope and H'=1.385 at western slope. Dominance-diversity curves of 16 sites showed Preston's lognormal distribution with small variations among them. It seems that the dominance diversity reflects the differences in the coenocline of their sites. The top 10 dominant species in species sequence of 113 tree species in whole the mountain, were noticed: Quercus mongolica, Pinus densiflora, Acer pseudo-siebold anum, Quercus serrata, Carpinus laxiflora, Styrax obassia, Fraxinus rhynchophylla, Tilia amurensis, Lindera obtusiloba and Abies holophylla in order.

An explanatory survey was conducted to assess preference and consumption pattern of horticultural species, their sources, location-wise planting preferences and diversity of these species in the rural homestead forest of the offshore island of Bangladesh. Assessment was done through multistage random sampling. Based on homestead size respondents were categorized into small (<0.05 ha), medium (0.05-0.25 ha) and large (>0.25 ha) and twenty from each category were selected randomly for the study. The study revealed that most of the farmer (75.5%) preferred to plant fruit tree species for future plantation followed by timber species (62.2%). But fruit-bearing plants were being gradually replaced by some exotic timber species such as Swietenia mahagoni, Acacia auriculiformis, Tectona grandis, Eucalyptus spp., etc. Diversity and abundance of fruit species was found higher in almost all homestead. A total of 41 horticultural species were identified and seven horticultural species among them were recognized as the most preferred ones in the study area. Consumption pattern was chiefly to meet the nutritional demand and to gain a quick monetary benefit. Average annual income from horticultural species was 7,183.33 Taka (US$102).

The theory of island biogeography has influenced strongly on the conservation and management issues of species diversity in the islands. The theory has not limited to islands in the ocean, but expanded to isolated and fragmented areas in the forests and urban. This study has a rare opportunity to explore the species diversity and abundance of birds in the islands of Korea. A total of 151 islands in the west and south areas in the Korean peninsula were examined. The number of species and the area of islands were highly significant (P<0.000) and the number of species and the distance from the mainland showed not so strong relationship. This indicated that bird species diversity has more influenced by the size of the islands not the distance. This can be from the study species of birds that can fly long distance, and also natural characteristics of migratory and resident status. Species-area curve showed that the z-value was 0.21 indicating the area and the bird species are strongly correlated. The long-term monitoring of bird species presence in the islands should be followed for a proper management plan.
