Background: In this article, it was analyzed how snow melting affects the assembly of lichen and moss communities in a small area of the coastal region of Barton Peninsula, which is in maritime Antarctic. In the small area, even though there is a huge gap of difference of the environment between the snow-filled area and snow-melt one, the latter did not have distinctive environmental gradients. Results: Depending on the snow melting time, coverage and species diversity of lichens and mosses tend to increase remarkably. For species with significant changes depending on the snow-covered period, there are Andreaea regularis, crustose lichens, Placopsis contortuplicata, Usnea aurantiaco-atra, and snow algae. In this area, the process of vegetation assembly process has shown the directional development in the order of snow algae${\rightarrow}$crustose, lichen sub-formation${\rightarrow}$fruticose lichen, moss cushion sub-formation (Andreaea sociation)${\rightarrow}$fruticose lichen, and moss cushion sub-formation (Usnea sociation), according to the order of snow melting. These directional development stages are shown in gradual change in small area with the snow melting phenomena. However, in the snow-free area, where water is sufficiently supplied, it is expected that moss carpet sub-formation (Sanionia sociation) will be developed. Vegetation development in the small area with the snow melting phenomena, depending on differences of resistance on snow kill and moisture settled by species in according to the time of snow melting, tolerance model to form community is followed. Conclusions: The research results explain the development of vegetation in the Antarctic tundra and its spatial distribution according to the period for growth of lichens and mosses in the summer time by differences of snow melting in the small area. In the future, if research for the community development process in a large scale will be done, it will be helpful to figure out temporal and spatial dynamic of vegetation in the Antarctic tundra where snow and glaciers melt rapidly due to climatic warming.

본 연구는 실내 조경 및 분화용 소재로 활용가치가 높은 물가양털이끼(Brachythecium rivulare)와 쥐꼬리이끼(Myuroclada maximowiczii)의 적정 재배법을 개발하기 위하여 수행하였다. 원예상토 위에 천을 덮어 재배하는 것이 재배용기에 천이나 토양만 사용하는 방법에 비해 이끼 2종의 생육이 왕성하고, 수확이 편리하였다. 재배 토양은 바크나 피트모스 보다는 원예상토를 사용하였을 때 생육 및 수확의 편이성이 우수하였다. 식재할 때는 이끼를 분주하는 것 보다 믹서기로 분쇄하여 재배용기 위에 산포하는 방법이 이끼 2종의 배우체 발생과 수확 편이도 개선에 효과적이었다. 또한 재배용기($27{\times}17{\times}3cm$)에 물가양털이끼는 2.0 g, 쥐꼬리이끼는 4.0 g을 식재하였을 때, 생육이 가장 왕성하였고 수확이 편리하였다. 양액(N:P:K=20:20:20)을 농도별로 처리하였을 때 물가양털이끼는 무처리구에 비해 전반적으로 생육이 억제되었고, 고농도로 갈수록 생체중의 증가량이 감소하였다. 그러나 쥐꼬리이끼는 $0.25g{\cdot}L^{-1}$ 처리구에서 생체중의 증가량이 가장 많았다. 따라서 물가양털이끼와 쥐꼬리이끼는 원예상토 위에 천을 덮어서 만든 재배용기에 각 2.0, 4.0 g의 이끼를 분쇄하여 산포한 다음 충분한 수분을 공급하고, 쥐꼬리이끼는 재배기간 동안 저농도의 양액을 처리해주는 것이 적합한 재배법으로 생각된다.

1991년 3월부터 1993년 6월까지 공단, 준공단 및 비공단지역에서 빗물을 채취하여 pH를 측정하고, 공단과 비공단지역에서 NH4+, NO3-, SO42- 및 전기전도도를 1년동안 측정하였다. 또한 황산과 질산의 1:4로 하여 pH4.6, 3.6 및 2.6으로 조정한 산성강하물이 털깃털이끼의 NRA, 광합성 및 수분포텐셜에 미치는 영향을 조사하였다. 빗물의 pH는 모두 이른 봄에 낮고 여름에 높았으며 공단지역의 낮은 pH는 다량의 이온 특히 SO42-와 관련되었다. 빗물의 SO42-, NO3- 및 NH4+의 월 평균은 공단지역에서 각각 2.94(81.0%), 0.48(13.2%) 및 0.21(5.78%)mg/l 이었고, 비공단지역에서는 각각 0.61(64.21%), 0.25(26.3%) 및 0.9(9.5%)mg/l로 공단지역에서 높았다. 공단지역에서 생육하는 Hypnum plumaeforme의 NRA의 비공단지역에 비하여 공단지역의 것이 낮았고, 산성강하물로 24일 동안 처리한 NRA를 측정한 결과 공통적으로 억제되었다. 공단지역과 비공단지역에서 생육한 식물의 광합성능은 산성강하물 처리후 24일만에 pH3.6에서 각각 85와 80%이상 회복되었으나 pH2.6에서는 66과 56% 회복되었다. 공단과 비공단의 식물체의 수분포텐셜은 산성강하물에 대한 뚜렷한 차이를 보이지 않았으나 단수후 모두 크게 낮아졌다.

The Environment consolation and the Tour Resources Development of the Cave. The conservation and the development of the cave are complementary to each other. On account of Keepiny on changing, the cave is similar to living thing. Therefore, the cave development mocks the environment changed by the microbes and the mosses by many factors. But if can make the people around the cave get richer and richer by the visitors. If we need to develop some caves, first of all the safety diagnoses must be executed, about the geographic structures, path facilities, electronic ones, and so on.

The cave is similar to living things, because of keeping on changing. The environment in the cave after developing it change because many factors as followings; The microbes and the mosses by visitors and inner facilities will grow in the cave, which makes the ecology a lot of change. The quality of water and air in the cave can lead to the destruction of the ecology by the development. So we do our best to conservate the cave without changing the environment of air, the water and the ground.

This study was carried out to investigate the moss flora of Barton Peninsula on King George Island of Antarctica. The study presented here was based on field surveys of Barton Peninsula conducted by the author during the austral summer season in 2012/2013, 2013/2014, 2014/2015 and herbarium specimens from Hiroshima University. The result of the study showed that the moss flora Barton Peninsula consisted of a total of 35 species, with 11 families and 21 genera.

This paper describes the cumulative deposition of fallout Pu in soil and lichen at the present time and give the characteristics of fallout Pu deposits in the soil. In the soil of the forest, the accumulated depositions of $^{239,240}Pu$ were estimated to be in the range of 34.0 to $101.2Bq\;m^{-2}$ with an average value of $65.3{\pm}21.6Bq\;m^{-2}$. The average inventory of $^{239,240}Pu$ in the forest was calculated to be two times higher than that in the hill. Also, the deposited activities of $^{239,240}Pu$ in cultivated soil were significantly lower than those in the hill or forest. However, the cumulative depositions of fallout Pu in the volcanic ash soil on Cheju Island were much higher than those in the forest and hill soils. The measured activity concentrations of Pu isotopes in lichens and mosses showed large variations, due to characteristics of species and life span of lichen and moss colonies. From depth profiles, it was found that most of the fallout Pu has been accumulated in upper 10 cm layer of soil. Except for a few cases, the concentrations of $^{239,240}Pu$ in soil tended to decrease exponentially with increasing soil depth. Among parameters affecting the cumulative deposition of fallout Pu, organic substances and rainfall play an important role in the retention and relative mobility of fallout Pu in the soil. However, pH showed a weak correlation with the deposition of fallout Pu in the soil. From sequential leaching experiments, Pu was found to be associated predominantly with the "organic" and "oxy-hydroxy" fractions. Both the activity ratios of $^{238}Pu/^{239,240}Pu$ and $^{241}Pu/^{239,240}Pu$ in soils, lichens and mosses and the atomic ratios of $^{240}Pu/^{239}Pu$ in soils are close to those observed in the cumulative deposit global fallout from nuclear weapon testings. The results obtained from this research make it possible to interpret and predict the behavior of fallout Pu under natural conditions.
