Daehuksan Island (125°23'-125° 28' E and 34°37'-34°42' N, ca 19.7㎢) in the southwestern part of Mokpo, Korea, is a part of the Dadohae National Marine Park. Most of the actual vegetation of the island is substitutional vegetation under various human impact such as grazing, cutting for firewood. And natural vegetation is partially distributed in the tutelary shrine forests, deep valleys, etc. During 1987, phytosociological investigation of this was carried out on the basis of Braum-Blanguet's method. The forest vegetation was classified into 1 association and 7 communities, Camellia japonica, Machilus thunbergii, Ardisio-Castanopsietum sieboldii, Daphniphyllum macropodum-Quercus acuta, Pyrrosia lingua-Pinus densiflora. Rhododendron mucronulatum-Pinus thunbergii, Carpinus coreana, and Psedosasa japonica community. Grassland vegetation was classified into Gleichenia japonica, Gleichenia dichotoma, Arundinella hirta-Miscanthus sinensis, Artemisia princeps var. orientalis. Imperata cylindrica var. koenii Artemisia princeps var. orientalis-Pennisetum alpecuroides, Carex boottiana, and salt marsh vegetation. Thypa orientalis, Spergularia marina, Phragmites communis, Carex scabrifolia, and Triglochin maritimum community. Based on them, the actual vegetation map was made in 1:50,000 scale.

The feeding habits of Pacific bluefin tuna, Thunnus orientalis were analyzed using samples by large purse seine fishery in Korean waters from 2012 to 2017. The number of samples was 1,274 and the fork-length (FL) ranged from 34.6 to 218.0 cm. According to %IRI, the Important main prey items of immature individuals (below 91.4 cm in FL) were Pisces, Cephalopoda and Euphausiacea and those of mature individuals were Cephalopoda and Pisces. T. orientalis showed ontogenetic changes in prey item that Pisces was dominated in size class of 30-89 cm (FL), Cephalopoda in 90-179 cm (FL), and Pisces above 180 cm. As for seasonal changes in prey item, Cephalopoda was dominant in spring and Pisces was dominant in summer, autumn and winter. %F, %N, %W and %IRI cluster analysis divided area into three groups: Group A was dominated by Pisces; Group B was dominated by Cephalopoda, and Group C was dominated by Euphausiacea.

한국에 살고 있는 다람쥐(Tamias sibiricus barberi)의 형태적 형질, 염색체 핵형 및 미토콘드리아 DNA 절단단편의 변이의 정도를 파악하기 위하여, 다변량분석, 골수세포 및 blot-hybridization법으로 표본들을 분석하였다. 아종 barberi의 분류학적 재검토를 위하여, 만주에 살고 있는 다람쥐(Tamias sibiricus orientalis)의 표본들의 형태적 형질들도 함께 분석하였다. 한국의 6개 지역의 다람쥐는 서로 형태적으로 유사했으며, 만주산 다람쥐는 한국의 다람쥐와 다른 군을 형서알 정도로의 뚜렷한 형태적 차이를 보이지는 않았다. 한국의 4개 지역의 다람쥐는 동일한 핵형(2n = 38)을 가졌고, 5개 미토콘드리아 DNA clone이 나타난 한국의 3개 지역의 다람쥐의 미토콘드리아 절단단편의 양상도 서로 유사하였다. 한국산 다람쥐는 단일한 집단이며, Corbet(1978)가 지적했던대로 아종 barberi는 아종 orientalis의 synonym임이었다. 한국과 만주산 다람쥐의 학명은 T.sibiricus orientalis이지만 분류학적 재 검토를 위하여 북한, 만주 및 중국의 표본들을 사용한 계통분류학적 연구가 필요하다고 본다.

A new euthyplociid burrowing mayfly (Polymitarcyidae, Ephemeroidea, Ephemeroptera), Polyplocia orientalis n. sp., from Vietnam is described with larval habitus and line drawings of mouthparts. The larva of the species is characterized by the mandibular tusks that bear numerous hairlike and stout setae on their dorsal and lateral surfaces and by the apical process of foretibiae that is nearly one-fourth the length of foretarsi. Its habitat and biological data and taxonomic remarks are provided. The burrowing mayfly subfamily Euthyplociinae is reviewed from a historical perspective.

A new species belonging to the genus Cyclopinoides Lindberg, 1953 (Cyclopinidae) is described from three beaches in Korea and Japan, as the first record of the genus from the Pacific. Among five species currently recognized in the genus, the new species resembles C. schulzi Herbst, 1964 from the Red Sea in sharing the character combination of 20-segmented antennule and stumpy caudal rami. However, C. orientalis n. sp. differs from it by relatively longer caudal rami (2.5-2.8 times as long as wide in female and about 1.6-1.8 times in male, while less than 2 times in female and about 1.3 times in male of C. schulzi), and by the transformation of an outer distal spine to a slender seta on the distal exopodal segment of leg 4. Moreover, C. orientalis n. sp. is discernible from C. schulzi in having a pyriform copulatory tube (against elongated tubular style in C. schulzi). A key to the species hitherto known in the genus is provided.

In order to elucidate the differences in early successional development among similary aged old-fields having different soil nitrogen (N), caused by the land use history before at abandonment, the response of plant community along an experimental nitrogen gradient (control plot (No), plot NI with 5.8g $N/m^2$, plot N2 with 11.7g $N/m^2$ and plot N3 with 23.3g $N/m^2$) was investigated in a five-year-old abandoned field. Although the N content in soil among treatments was similar at the end of the growing season, N concentrations in plant tissue increased with the amount of N supplied. These results suggest that almost all the N contained in N-enriched soil might be absorbed by plants during the growing season after N supply. Vegetation tended to grow vigorously by nitrogen supply, and the standing biomass increased significantly in plots NI and N2 . Species richness of plants, especially of annuals and perennials, was more reduced than the control plot, and the species diversity was also reduced by N supply. The importance value (IV) of species by N supply differed in each species along the position on the successional sere: Artemisia princeps var. orientalis as the dominant species in this old-field decreased slightly; annuals as the earlier successional species decreased clearly along nitrogen gardients; Erigeron annuals as the earlier successional species and as a strong competitor with Artemisia princeps var. orientalis had the highest IV by small N supply; Miscanthus sinensis and Rubus crataegifolius as the later successional species increased by large N supply. These results suggest that old-fields with high soil N might show the structural and functional characteristics of the earlier successional stages, but community composition in those old-fields might be changed more quickly from the sarlier successional species than the later successional species.

국내에 분포하는 나자스말속(Najas L.) 분류군의 형태적 변이를 파악하고 각 분류군의 식별형질을 검토하기 위하여 32개 정량형질을 이용하여 주성분분석을 수행하였다. 나자스말속의 분류군에서 잎의 너비, 엽초의 모양, 엽연의 거치수, 약실의 수, 한 줄에 배열하는 종자의 그물눈 수와 길이의 비 등이 유용한 식별형질로 파악되었다. 자웅이주인 민나자스말(N. marina)은 잎과 줄기, 수꽃과 암꽃, 열매가 대형으로서 자웅동주인 다른 분류군들과 뚜렷하게 구분되었다. 자웅동주인 분류군들 중에서 나자스말(N. graminea), 실나자스말(N. gracillima), 동아나자스말(N. orientalis)은 영양 형질에 의하여 식별이 가능하지만, 톱니나자스말(N. minor)과 큰톱니나자스말(N. oguraensis)은 수꽃에 있는 약실의 수에 의해서만 구분되었다.

Litterfall, decomposition, and dynamics of n and p in decomposing litter were investigated for 2 years in red pine ( pinus densiflora) and chinese thuja( thuja orientalis)stands in the limestone area. Average litterfall in red pine and chinese thuja stands were 4, 535kgDM ha-1 yr-1 and 5, 010 kgDM ha-1 yr-1, respectively. Seasonal litterfall in red pine and chinese thuja stands showed peaks in November. concentrations of N and P in the needle litter were lowest in the winter when the greast litterfall occurred, and highest in the summer when the least litterfall occurred. However, those in chinese thuja scale leaf litter showed litter seasonal variation.amount of N and P returned to the forest floor through litterfall were 29.02kgN ha-1 yr-1 , 2.81 kg P ha-1 yr-1 for red pine stand, and 31.06 kg N ha-1 yr-1 , 2.86kgP ha-1 yr-1 for chinese thuja stand, respectively. After 21 mounts elapsed, needle and chinese thuja scale leaf litterbags lost 34.8% and 32.5% of the initial weight, respectively. N concentrations in the docomposing needle and chines thuja scale leaf litter decreased by 19% and 30%, respectively, after 1 month elapsed, and then gradually increased to exceed the initial concentration after 9 months elapsed and then gradually increased to exceed the initial concentration after 9 months elapsed in both of them, P in needle and chines thuja scale leaf litter decreased by 54% and 57% of the initial concentration, respectively, after 1 month elapsed. unlike N, P concentration in the decomposing litter did not exceed that of initial ones. Neyt immobilization period of N and P in decomposing litter did not occur over the study period.
