  • The objective of this study was to discuss the characteristics of the moss flora of Mt. Deogyu located on the border of the Jeonbuk and Kyungnam provinces in Korea. A total of 21 field surveys were carried out at various sites in the mountain area from August 2007 to September 2008. All the collected materials were processed into voucher specimens and were currently deposited in the herbarium at Chonbuk National University (JNU). In this study, we collected and identified 158 moss taxa, which included 156 species, 1 subsp. and 1 var. of 96 genera and 37 families. Unconfirmed taxa in this study, but previously recorded, belonged to 25 taxa, which included 13 families, 19 genera and 25 species. In addition, 183 taxa were found on Mt. Dreogyu, which belonged to 37 families, 101 genera, 1 subsp. and 1 var. The habitat of each collection was examined and the classification system of Ignatov et al. (2006) was used. New vernacular names of 6 families and 11 genera were then determined. Six species, formerly thought be only in North Korea, were shown to be present on Mt. Deogyu, which included Bucklandiella laeta, Anomobryum filiforme var. concinnatum, Herzogiella turfacea, Brachythecium rutabulum, Eurhynchium angustirete and Campylidium hispidulum.

  • This study was conducted to provide the informations for conservation and effective management of Picea yezoensis community in Mt. Deogyu and Mt. Gyebang. The vegetation of tree, subtree and shrub layer was consist of 8, 20, 26 species in Mt. Deogyu, and 12, 23, 33 species in Mt. Gyebang. Importance value by layer P. yezoensis, Betula ermanii, Abies koreana at tree layer, B. ermanii, Quercus mongolica at subtree layer, and Sasa borealis at shrub layer in Mt. Deogyu, and P. yezoensis, B. ermanii, Abies nephrolepis at tree layer, Acer komarovii and A. ukurunduense at subtree layer, and Tripterygium regelii at shrub layer in Mt. Gyebang were high, respectively. Species diversity in Mt. Deogyu and Mt. Gyebang were 0.779 and 0.984 at tree layer, 1.052 and 1.161 at subtree layer, and 0.823 and 1.304 at shrub layer, respectively. According to the DBH class of major species, P. yezoensis in Mt. Deogyu showed a reverse J-shaped curve, which was estimated that P. yezoensis community of this site might be maintained continuously as a stable state.

  • This study was conducted to classify community and verify vegetation structure of Picea jezoensis community in subalpine zone of Mt. Kyebang, Mt. Jiri, Mt. Deogyu, 39 releves set up and was carried out to analyze ordination. P. jezoensis Community was classified into Acer ukurunduense subcommunity, Quercus mongolica subcommunity, Syringa reticulata var. mandshurica subcommunity and P. jezoensis typical subcommunity. The order of important value of the forest community with DBH 2cm above plants was P. jezoensis (89.22), Acer komarovii (30.50), Abies koreana (18.81), Rhododendron schlippenbachii (18.10), Sorbus commixta (17.19), Betula ermanii (16.89), Pinus koraiensis (16.80), Taxus cuspidata (12.45), Acer ukurunduense (11.73). The DBH analysis suggests that P. jezoensis will maintain dominant position.

  • A total of ten unrecorded liverwort species in the Hepaticae flora of Korea were collected on Mt. Deogyu (1,614 m). The ten species are Tetralophozia filiformis (Steph.) Urmi., Herbertus buchii $Jusl{\acute{e}n$, Bazzania japonica (Sande Lac.) Lindb., Cephaloziella hampeana (Nees) Schiffner ex Loeske., Jungermannia japonica Amak., Marsupella alpina (Gott. ex Husn.) Bernet., Pedinophyllum interruptum (Nees) Kaal., Frullania polyptera Tayl., Jubula hutchinsiae ssp. javanica (Steph.) Verd., and Marchantia polymorpha ssp. montivagans Bischl. and Boisselier-Dubayle. They are distributed near streams and/or at the top of a ridge on Mt. Deogyu.

  • The lichen species collected from Mt. Deogyu were identified as beloning to eleven genera in four famillies: Anzia colpota, Cladonia bacillaris, Flavoparmelia caperata, Hypotrachyna phys­cioides, Nephromopsis asahinae, Parmelia fertilis, P. marmaiza, Parmotrema austrosinense, P. chinense, Xanthoparmelia mexicana, X. scabrosa, Anaptychia palmulata, Heterodermia hypoleuca and Physconia grumosa. Among the fourteen lichens, the genus name of Parmotrema austrosinense and Xanthoparme­lia scabrosa were changed by Hale, and Hypotrachyna physcioides was newly reported in Korea.

  • This study was carried out to classify the current forest cover types and to propose the successional trends in the natural forest of Mt. Deogyu. The vegetation data were collected by the point-centered quarter method. The forest cover types were classified by various multivariate statistical analysis methods such as cluster analysis, indicator species analysis and multiple discriminant analysis. This forests were classified into five forest types by the species composition of upper layer and topographic positions: Quercus mongolica forest in the ridge, Fraxinus mandushurica-F. rhynchophylla-Cornus controversa forest and F. mandushurica forest in the valley, the Q. serrata - Pinus densiflora - Q. mongolica forest and P. densiflora forest in the low-slope. As a result of the forest successional trends depending on ecological and environmental characteristics in each forest type, the current forest types were expected that the forest succession would be proceeded toward Q. mongolica forest, F. mandshurica forest, mixed mesophytic forest, and oak-Carpinus laxiflora forest.

  • In order to elucidate the human impact on the distribution of cellular slime molds, samples were collected from 3 types of forest ; natural forests(Mt. Deogyu and Mt. Tsukuba), semi-natural forests(Seoul Great Zoo and Tama Zoo), artificial forests(Seoul National University and Tokyo Gakugei University) .The distribution of cellular slime molds in mountains was different from that of zoo and universities. In mountains, endemic species was occurred and species diversity was higher than in zoo and universities. In zoo and universities disturbed by human, Dictyostelium sphaerocephalum was occurred with higher importance value than in mountains. 6 species were selected to investigate the effect of temperature on froctification; Polysphondylium canlidum, D. delicatum. D. firmibasis, D. sphaerocephalum P. violaceum, D. purpureum. P. violaceum and D. purpureum had an optimum temperature for fructification around 25~3O˚C but the others around 22~23˚C. The degree of sensitivity to temperature was as follows; P. candidum >D. lelicatum > D. firmibasis > D. sphaerocephalum > P. violaceum > D. purpureum. Key words: Human impact, Cellular slime molds, Occurrence and distribution, fructification, Dictylostelium delicatum. Dictyostelium sphaerocephalum.

  • This study was to analyze vegetation and soil characteristic, and ordination of Bupleurum euphorbioides community located in Mt. Seorak area, Mt. Sobaek area, and Mt. South Deogyu area. Bupleurum euphorbioides community was classified into Carex lanceolata subcommunity and Chrysanthemum zawadskii var. alpinum subcommunity, and Chrysanthemum zawadskii var. alpinum subcommunity was classified into Calamagrostis arundinacea and Carex breviculmis group. In the study sites, soil organic matter, nitrogen, available phosphorous, changeable potassium, changeable calcium, changeable magnesium concentration, cation exchange capacity, and soil pH were ranged from 9.0~15.2%, 0.32~0.47%, 3.0~8.6ppm, 0.3~0.9me/100g, 0.5~1.5me/100g, 0.2~0.6me/100g, 11.4~16.1me/100g, and 4.3~4.6, respectively. And, soil texture was sandy loam or loam. The Carex breviculmis group of Chrysanthemum zawadskii var. alpinum subcommunity was found in area of high elevation and had high exchangeable K, Ca, and Mg concentration. The Calamagrostis arundinacea group of Chrysanthemum zawadskii var.alpinum subcommunity was found in area of low elevation and had lower exchangeable K, Ca, and Mg concentration than in the other subcommunity. The Carex lanceolata subcommunity was found in area of medium elevation and had medium exchangeable K, Ca, and Mg concentration. The Carex lanceolata subcommunity was located in a path of top the mountain peak, and has been destroyed. We need any action to protect the subcommunity.
