  • Batch adsorption experiments were performed to adsorb cadmium [Cd(II)], copper [Cu(II)], and lead [Pb(II)] onto sphagnum peat moss. According to the results, 10-50 mg/L of Cd(II), Cu(II), and Pb(II) were effectively adsorbed and removed within 1 h by 1.0 g/L of sphagnum peat moss. The amounts of Cd(II), Cu(II), and Pb(II) adsorbed on sphagnum peat moss increased with increasing the initial concentrations. The kinetics for the adsorption of Cd(II), Cu(II), and Pb(II) on sphagnum peat moss was described well using the pseudo-second order model at different initial concentrations. The maximum adsorption capacities calculated from the Langmuir isotherm for Cd(II), Cu(II), and Pb(III) were 33.90, 29.15, and 91.74 mg/g, respectively. Experimental results showed that sphagnum peat moss was a very effective adsorbent on the adsorption of Cd(II), Cu(II), and Pb(II).

  • In the moor of Mt. Dae-am, the following communities are seen in successive order ranging from the north to the south; the Sanguisorba Argutipens-Carex jaluensis community, the Carex jaluensis-Sanguisorba Argutipens-Sphagnum community, the Sphagnum cymbifolium-Carex jaluensis community, the Carex jaluensis-Sanguisorba Argutipens community and the Calamgrostis Langsdorfii-Ottelia alismoides community. The properties of the peats vary according to the community type, that is, nutrients such as organic matter, total nitrogen, exchangeable K and Mg in the soil tend to decrease as the plant communities shift from the north to the south. The pH range for eleven stations samples was 3.9 to 5.7, and the meadian is 4.6. The content of exchangeable Ca decreases from station to station successively towards the center which is poor in calcium. Presumably there appears to be a clear correlation of Sphagnum cymbifolium with the amount of exchangeable Ca and value of pH produced in bogs by the breakdown or organic residures. The nutrient content of the representative plants of the moor shows no definite relation with the station of their habitats.

  • An exceptional case of inhabitation of a Sphagnum sp. was firstly confirmed at abandoned paddy terrace (APT) wetland in Ansan. Water sampling for analyzing of physicochemical conditions including nutrients such as NP, $Ca^{2+}$ and $Mg^{2+}$ was performed and the vegetation map for distribution of Sphagnum sp., topographical map, and flora list for companion species were made at field in June 2011. From the results, the Sphagnum sp. in the study site was identified as S. palustre and it covered about 8% of the wetland cover of 3,200 $m^2$. Most distributions of S. palustre were observed at tussock structures as micro-topography by sedges and grasses within a wetland (74%) and the shaded slope area under Pinus densiflora's canopy in wetland boundary (26%). Despite that APT in Ansan is relatively lower wetland in altitude than high moors, the contents of calcium ($0.45{\pm}0.2$) and magnesium ($1.48{\pm}0.6$) ion which are critical limiting factors for Sphagnum spp. were very low levels as well as NP ($PO_4$-P, $0.02{\pm}0.0$; $NO_3$-N, $0.25{\pm}0.3$; $NH_4$-N, $0.06{\pm}0.1$) and it could enable the inhabitation of S. palustre in lower APT.

  • In this study, ecological investigation was performed on Yong-neup, Daeam-san for 5 times. This area is considered DMZ zone located between Yanggu-gun and Inje-gun, Gangwon-do, where has been recognized highly valuable for ecological preservation. As a result, Sphagnum and hydrophobic vegetation were found in Little Yong-neup, revealing its characteristics of high moor, where as no Sphagnum were found in Baby Yong-neup. Thereby, the carnification has been investigated in both Little Yong-neup and Baby Yong-neup. A main cause of damage was associated with the creation of stating rink and increases of visitors. The damages of vegetation in Little Yong-neup and Baby Yong-neup have been intensified by road construction or uses of groundwater while relocating military troops to upper stream of Little Yong-neup and Baby Yong-neup, further causing the damages of water circulation system and soil erosion. These artificial factors have caused the carnification of wetland protection areas including Little Yong-neup. The terrestrial vegetations, such as Plantago asiatica, Geranium Koreanum and Artemisia feddei have increased compared to current survey conducted by the Ministry of Environment. 5 endangered species, such as Lychnis wilfordii and Trientalis europaea and 5 other introduced species, such as Aster pilosus and Taraxacum officinale were found. 10 different species of mammal and 2 species of amphibian were investigated; and in addition to this, a original form of Sphagnum fens, the remaining wetland was found. Therefore, this study is to identify the causes of damages in Little Yong-neup and Baby Yong-neup through their ecological survey and accordingly proposing a direction for ecological restoration through the improvement of water circulation system, creation of habitats for plant and animal, restoration of vegetation through eco-friendly materials and indigeneity, relocation of the current military troops, securing of structural stability.

  • Sphagnum palustre (SP), a species of moss belong to the Sphagnaceae family, is used as a dwarfed potted plant, in diapers, bandages, and soil additives. Although, SP can be found all over the world and is very cheap, the study of SP components and bioactivities are still at a rudimentary stage. In this study, the hot-water extract of SP (HWSP) and its subsequent organic solvent fractions were prepared, and their in-vitro anti-thrombosis activities were evaluated. The results showed that the water residue of HWSP has a strong anti-coagulation activity with significant extensions of thrombin time, and platelet aggregation activity. Our results suggest that the SP has the potential to be a novel resource for anti-thrombosis agents. This report provides the first evidence of the anti-thrombosis activity of SP.

  • In order to assess the impacts of drawdown for land-use change on a Sphagnum-marsh, we compared the vegetation and flora of the wetland before and after the drawdown with focusing on the population of Sphagnum palustre L. Remarkable changes in the coverage of S. palustre and the major vegetational components of the wetland were observed. The coverage of S. palustre markedly decreased by about 75% (from approx. 247 ㎥ in 2011 to approx. 62 ㎥ in 2015) after the drawdown. Tree species such as Salix spp. extended (from about 70% to about 83% in the total coverage of the wetland), whereas herbaceous species shrunk after the drawdown. Upland-inhabiting species such as obligate plants for uplands (OBU) increased, whereas wetland-inhabiting species such as facultative plants for wetlands (FACW) and OBW decreased in terms of vegetational coverage. The total number of plant species decreased from 70 species to 62 species after the drawdown, including the disappearance of some wetland-inhabiting species from the wetland. We suggest that the attention for further studies on the abandoned paddy terraces (APTs) and effort for the management and conservation of APTs and APT-inhabiting species that are vulnerable to human-induced disturbances have to be paid more.

  • The effects of media, cell sizes and fertilizers on the early growth of Phalaenopsis plug plants were investigate. The sphagnum moss was more effective than other media in pink and white color cultivars. In comparison of different plug cell size, 50 cell size was more effective then 72 and 128 cell size in pink and white cultivar. In comparison of different fertilizer, margamf K in pink, and nutrient solution II(one time drenching with NHRI standard solution for three times irrigation) in white color cultivars was more effective then others, respectively.

  • We investigated the ecological characteristics of Jilmoe-neup conservation area which is one of wetlands designated as a Ramsar convention site in Mt. Odae from 2007 to 2011. Average out-flow of water was 0.80 $m^3/min$ during observation period. Average pH of water was 6.1, electric conductivity was 19 ${\mu}S/cm$ and contents of potassium, calcium and ammonium, nitrate and available phosphorus in water were recorded below average 2.0 mg/L. Peat layer was less developed than in other montane wetlands such as Yong-neup and Wangdeungjae-neup. Plants were recorded as 49 family, 118 genus, 163 species, 3 subspecies, 29 variety and 6 forma, total 163 taxa. Trientalis europaea L., which was designated in endangered level 2 by Ministry of Environment, inhabited at Sphagnum dominated area and Carex tussocks. Vegetation analysis showed that dominance value was changed as species distribution area were increased or decreased periodically. Although Jilmoe-neup deserved conservation value for Sphagnum fen which has diverse flora, it was affected from various factors such as ranch in the vicinity. Therefore, it must be monitored and managed continuously.
