  • This research focuses primarily on the feasibility of applying bryophyte to man-made structures in modern urban environment. The study is based both on the role of bryophyte known in the process of the naturalization that life has come on the land and the physiological and ecological characteristics of bryophyte. The primary characteristics of this species lie in its desiccation-tolerance and poikilohydry that supports its enduring survival even under the desperate environmental conditions. The monitoring of applying bryophyte to man-made structures has shown us that bryophyte could control microclimate conditions, help to mitigate flood by reducing runoff, and lessen thermal conductivity, etc. The application of bryophyte to man-made structures has just started since 2002. Even though efforts to use bryophyte in greening man-made structures in Japan and Korea have resulted in both successes and failures, it is noticeable that there has been quite much technical progress in using this unique plant species.

  • It is important to consider urban parks and greenery not only from the viewpoint of amenity or aesthetics but also from the viewpoint of biodiversity. In this study, we focused on bryophytes (mosses), and analyzed how existence of artificial structures in urban greeney, such as concrete curbs and stone walls, affect species diversity of bryophytes. Kyoto Gyoen in Kyoto City, western Japan, was selected as the study site. In consideration of kinds of substrates on which bryophytes grow, microhabitats of Kyoto Gyoen were divided into ten types including concrete curbs and stone walls. In each type of microhabitats, we selected the area where bryophyte diversity was highest, and established a quadrat for bryophyte flora survey. Our results showed that the number of bryophyte species and growth forms and the value of diversity indices on concrete curbs or stone walls were higher than the averages of those. The bryophyte species were divided into the four groups by TWINSPAN as follows: Group A (epiphyte species), Group B (rocky species), Group C (roadsides, grassland or forest species), and Group D (waterside species). Bryophytes classified into Group B (rocky species) were mainly recorded on concrete curbs or stone walls. It was considered that the existence of artificial structures (concrete curbs and stone walls) provided favorite habitats for the bryophytes classified into Group B (rocky species), which mainly grows on concrete or rocks, and enhanced species diversity of bryophytes in Kyoto Gyoen.

  • 덕유산에 분포하는 침광혼효림의 임상선태류군락을 식물사회학적 관점에서 연구하였다. 그 결과 고등식물군락의 조성에 대응하여 조릿대-구상나무/아기호랑꼬리이끼-여우꼬리이끼군락을 식별하였다 이 군락은 지리산에 분포하는 조릿대-구상나무/비꼬리이끼-수저잎산주목이끼군락의 동위군락으로 해석되었으나 군락 사이에 임상선태류군락의 조성은 다소 다르게 나타났다. 식물사회학적으로 조릿대-구상나무/아기호랑꼬리이끼-여우꼬리이끼군락은 쇠물푸레-구상나무군집에 속하는 하나의 분층군락으로 확인되었다 지금까지 많은 연구자가 지리산지와 덕유산에 분포하는 침엽수림을 아한대(=아고산대)의 식생으로 취급하였다. 그렇지만, 현 연구결과는 식물사회학적 입장에서 덕유산의 침광혼효림이 냉온대 낙엽수림대의 식생임을 명백히 나타내었다. 덕유산 침광혼효림의 임상선태류의 종다양성은 지리산의 침광혼효림의 것과 대개 비슷한 수준이었다. 덕유산 침광혼효림의 임상선태류 분류군은 19과, 25속, 38종으로 구성되었다.

  • The physico-chemical and environmental factors of stoneworks were examined from March 2009 to October 2010, and aerial algae living on 24 stoneworks in Korea were identified. Fifty aerial algae were found in 24 stoneworks. Of the 50 taxa, 30 taxa were cyanophytes, 16 taxa were bacillariophytes, 3 taxa were chlorophytes, and 1 taxon was a xanthophyte. Nine species, including Aphanocapsa rivularis, which is known to only live in aquatic conditions, inhabited both aquatic and aerial environments. Synechococcus aeruginosus, Scytonema coactile var. thermalis, S. coactile var. minor, Stigonema ocellatum f. ocellatum, and Oscillatoria boryana were newly recorded in Korea. As a result of a correlation analysis between algae and the physico-chemical and ecological environmental factors, the taxa were divided into the bryophyte group, the humidity group, and the dry group. Although the bryophyte group was included within the humidity group, it was separated from the dry group. Taxa in the bryophyte group including Nostoc commune which was distributed in more humid areas than those in the humidity group. However, dry group taxa including Chroococcus pallidus were distributed in lower humidity than that of the two other groups. Correlations among other environmental factors were tested to identify other factors that could substitute for humidity and light intensity. As a result, tree distance, water distance, and plant coverage were replaceable environmental factors.

  • Recently, it has become known that Gotjawal terrain is an important area, therefore the study on this area has conducted in the geological, ecological, and cultural aspects. The studies on bryophytes of Gotjawal, however, have not been sufficiently performed. This study presents a survey on the bryophytes of the evergreen broad-leaved forest of Cheongsu-ri at Hangyeong Gotjawal in the southwestern part of Jejudo Island, Korea. A total of 72 taxa belonging to the Bryophyta (18 families 43 genera 55 species) and Marchantiophyta (11 families 13 genera 17 species) were determined and the liverwort index was 23.6%. Predominant life-form was weft. The rates of the bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that the forests are widespread and dense in this study area. Upon an investigation of the substrates, the bryophytes on rocks were most diverse. The results appear to stem from the fact that volcanic rock masses of various sizes lay scattered over the study area, offering numerous micro-habitats for bryophyte due to one of the characteristics of Gotjawal. We suggest that more detailed studies should be conducted at the regional scale to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests on Jejudo Island.

  • This study presents a survey of the bryophytes of evergreen broad-leaved forest near Baekyaki Oreum in Gujwa-Seongsan Gotjawal in the eastern part of Jejudo Island, Korea. A total of 53 taxa belonging to Bryophyta (11 families 26 genera 39 species) and Marchantiophyta (9 families, 9 genera 14 species) were determined, and the liverwort index was found to be 26.4%. The predominant life-form was the mat type. The rates of bryophytes dominating at mesic to hygric sites were higher than those of bryophytes, which were mainly observed in xeric habitats. These values indicate that the forest areas in this study area have a high density level. Upon an investigation of the substrates, bryophytes on rocks were most diverse. It was also found that volcanic rock masses of various sizes lay scattered over the study area and offer numerous micro-habitats for bryophytes. This is related to the characteristics of Gotjawal. We consider that more detailed studies should be conducted on regional scales to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests of Jejudo Island.
