To examine the proportion of secondary seed dispersion by wildlife and to identify the related wildlife, We measured seed removal rates and related wildlife at the natural mixed broadleaved forest in mountain Jungwang, Pyeungchang-gun in middle part of Korean peninsula, seed-tray contained four kind of tree seeds were setted from mid-september to late-October for three years. Mean seed removal rates(MSRR) of acorn(Q. mongolica)is shown the highest values 87.2%, next MSRR of samara(A. pseudosieboldianum) does 33.1%, MSRR of samara(A. pictum subsp. mono) does 29.2%. and then SRR of samara(A. mandshuricum) does only 13.6%. Acorns are removed more faster than samaras. Among the related wildlife, Siberian chipmunks most freqently visit seed tray, and ordered Korean squirrel, Wild boar, and Yellow-throated marten. Most secondary dispersed acorns might be consumed by Wild boar, and small portions does comsumed or scatter-hoarded by rodents. Most secondary dispersed samaras might be consumed by rodents, and small portions does scatter-hoarded by rodents. A few sound seeds are remained on the forest floor in late October owing to the seed consunption and seed hoarding by wildlife. We observe seedling establishment of four broadleaved tree species. From these results, We proved Wild boar is seed comsummer, and rodents are seed consummer and seed disperser. Further studies on secondary seed dispersion, seed consumption and hoarding and related wildlife should be needed.

"가을을 상징하는 과일 중 밤나무의 밤 송아리처럼 가을을 대변하는 전령사는 드물 것이다. 가을 빛 영롱한 숲속에서 하늘과 당과 구름과 별과, 햇빛과 바람이 시를 읊고 있는 가을은 가시 속에 아롱진 꿈이 밤송이 되어 바람결에 빗방울처럼 떨어져도 겨울에 먹을 음식이 다람쥐와 청설모에게는 모자라는 안타까움이 인간의 욕심을 새삼 느끼게 하는 구나! 이렇게 우리에게 넉넉함과 즐거움을 주는 밤나무는 양수로서 바람이 적은 산록이나 저지대의 토심이 깊은 비옥토에서 잘 자라며, 맹아력이 좋고 수세가 강건하다. 과실은 예로부터 식용대용으로 각종음식을"

The pancreatic endocrine cells, glucagon and somatostation, of the Korean tree squirrel. Sciurus vulgais corea, were investigation by means of light and electron microscopic immunohistochemistry using the PAP and protein A-gold techniques. Glucagon-immunoreactive cells were distributed the periphery and occasinonaly central region of the pancreatic islets. Also, isolated cell was found between the pancreatic ancinar cells. The glucagon cells contraine granules with a diameter of 240~320nm and the electron dense core usually surrounded by a halo of less dense granular material. The core of granule was labelled strongly with gold particles. Somatostatin-immunoreactive cells were weakly stained in scattered along the peripheral pancreatic islets and were distributed as singly or small groups with in the pancreatic acinar cells. The somatostatin cells were spherical with a diameter of 250~275nm, moderately electron opaque (Gold particles were mostly demonstrated on the entire granule.

This research had been executed to find out the structure of Magnolia obovata community, a dispersal range and characteristics of scatter investigation, and to prepare management measure of it. In the result of this study, Magnolia obovata was distributed in a native plant community from planting trees of UNESCO Peace Center. The maximum numbers of Magnolia obovata were found in $20{\sim}100m$ from trees of mother. Seed of Magnolia obovata has a characteristics of gravity dispersal. But some individuals was found in 420m from its tree of mother. Seeds of Magnolia obovata has a characteristics of animal dispersal, too. Major species of animal dispersal are Garrulus glandarius, Ciurus vulgaris coreae, and Tamias sibiricus asiaticus in the study site. The importance value between native plants and Magnolia obovata had a negative relation. Because Magnolia obovata is more shade tolerant than other trees. Also, the growth of Magnolia obovata is faster than other trees. And so if the influence of Magnolia obovata reduce, it is necessary to expand native plant community, and to cut Magnolia obovata over 10m of the height and over 10cm of the DBH, for preventing influence of Magnolia obovata.
