분자생물학적 기법에 의한 우도해안과 노지암석에 분포하는 지의류의 생태학적 분석

Abstract

This study was initially performed to obtain fundamental data on lichen distribution depending on environmental condition. Lichens distributed on coastal rocks at least 20 m far away from the coast were also investigated. Analyses of morphological characteristics and rDNA ITS clones revealed that lichens containing 9 families and 15 genera were distributed in coastal rocks of U-do, while lichens containing 10 families and 14 genera were in field rocks, demonstrating little difference of diversity between both sites. Foliose lichens such as Phaeophyscia, Physcia, Pyxine belonging to the family Physciaceae were representatives distributed in coastal rocks of U-do, along with Xanthoparmelia belonging to Parmeliaceae, fruticose lichens such as Ramalina to Ramaliaceae, and crustose lichen Lecanora to Lecanoraceae. In contrast, foliose lichen Cladonia belonging to the family Cladoniaceae, fruitcose lichen Stereocaulon to Streocaulaceae, and crustose lichen Porpidia to Porpidiaceae were found only on the surface of field rocks. Crustose lichens containing genera Caloplaca, Candelaria, Dirinaria, Graphis, Rhizocarpon, and Pertusaria were rarely distributed in coastal rocks, and most of them were also found in field rocks.
