  • 전라남도의 해안에 방치된 염전에 생육하고 있는 식생에 대하여 군락 분류학적 연구와 토양의 특성에 대한 연구가 수행되었다. 본 연구는 종조성을 바탕으로 Mueller-Dombois와 Ellenberg 법에 따라 수행되었다. 본 연구의 목적은 전남 해안에 방치되어 있는 폐염전의 식물군락분류를 통한 식생형을 규정하고, 군락생태를 밝히는데 있다. 폐염전에 분포하는 일년생 초본 염생식물군락은 퉁퉁마디군락, 칠면초군락, 해홍나물군락, 가는갯능쟁이군락, 갯개미자리군락으로 밝혀졌다. 그리고 다년생 초본 염생식물군락으로는 갯개미취군락, 천일사초군락, 갈대군락으로 분류되었다. 본 연구의 결과는 해안 습지 식생에 대한 군락분류 및 구성종에 대한 정보의 축적을 가능하게 하고, 아울러 해안 습지 생태계 보전을 위한 기초자료로 유용한 정보를 제공한다.

  • Aboveground net productions of four stands in the coastal salt marsh of Incheon were estimated with three different methods: first method was to measure peak live standing crop; second to measure both live and dead standing crops; thrid to measure live and dead standing crops and dead disappearance as well. Net productions estimated by the first method were lowest with a difference of 28~50% from those by the third method. Whereas estimates by the second method approximated considerably to those by the third method with a difference of 4~15%. The third method figured out the highest values and seemed to be most appropriate in estimating net production of herbaceous community. Form these results it is known that live standing crop, dead standing crop and dead disappearance respectively accounted for about 60, 30, 10% of net production estimated by the third method. Annual net productions estimated by the third method for Suaeda japonica-Salicornia herbacea, Artemisia scoparia-Limonium tetragonum, Calamagrostis epigeios, and Sonchus brachyotus-Setaria viridis stand were 650, 1, 080, 1, 409 and 1, 126 g.$m^{-2}.yr^{-1}$, respectively.

  • Fungal endophytes are symbiotic microorganisms that are often found in asymptomatic plants. This study describes the genetic diversity of the fungal endophytes isolated from the roots of plants sampled from the west coast of Korea. Five halophytic plant species, Limonium tetragonum, Suaeda australis, Suaeda maritima, Suaeda glauca Bunge, and Phragmites australis, were collected from a salt marsh in Gochang and used to isolate and identify culturable, root-associated endophytic fungi. The fungal internal transcribed spacer (ITS) region ITS1-5.8S-ITS2 was used as the DNA barcode for the classification of these specimens. In total, 156 isolates of the fungal strains were identified and categorized into 23 genera and two phyla (Ascomycota and Basidiomycota), with Dothideomycetes and Sordariomycetes as the predominant classes. The genus Alternaria accounted for the largest number of strains, followed by Cladosporium and Fusarium. The highest diversity index was obtained from the endophytic fungal group associated with the plant P. australis. Waito-C rice seedlings were treated with the fungal culture filtrates to analyze their plant growth-promoting capacity. A bioassay of the Sm-3-7-5 fungal strain isolated from S. maritima confirmed that it had the highest plant growth-promoting capacity. Molecular identification of the Sm-3-7-5 strain revealed that it belongs to Alternaria alternata and is a producer of gibberellins. These findings provided a fundamental basis for understanding the symbiotic interactions between plants and fungi.

  • Two copepod species of Leptocaris belonging to the family Darcythompsoniidae are recorded from sandy mud sediments of salt marshes in South Korea: L. brevicornis (van Douwe, 1905) and L. trisetosus pacificus n. ssp. The genus Leptocaris is newly known from Korea. Leptocaris trisetosus pacificus differs from the nominate subspecies in exhibiting a sexual dimorphism in setal armature of leg 3, that is, bearing an additional seta on the second endopodal segment of leg 3 in male and an allopatric geographical distribution. This paper deals with the description and systematic accounts of them with detailed illustrations.

  • 대규모 연안개발에 따른 매립사업으로 연안역의 갯벌 또는 염습지 등의 연안생태환경공간은 해마다 감소하고 있다. 이에 따라 연안역 자연환경의 완화조치(Mitigation)의 일환으로 인공갯벌 및 염습지 개발의 필요성이 대두되어 활발한 연구가 진행되고 있으나, 인공 연안공간 조성시 복원정도의 정량적 평가에 관한 연구는 미흡한 실정이다. 따라서 본 연구에서는 연안생태환경공간 조성지의 복원정도 평가에 대한 기초적인 연구로서, 준설토 배합비에 따라 구분되는 인공갯벌(Zone. P1) 및 염습지(Zone. P2) 현장시험구를 조성하여 생물-화학적 환경인자인 시험구 내 대형저서동물 군집의 생물다양성과 개체수 및 생체량/식생(갈대)의 정착률/종속영양세균수/이화학적 특성(COD, IL, TN, TP, pH)에 대한 환경성 모니터링을 수행하였다. 이 결과를 바탕으로 각 환경인자들의 복원정도를 나타내는 복원지수를 제안하여 연안생태환경공간 조성에 따른 복원정도를 정량적으로 평가하였다.

  • Two species of the genus Isotomurus $B{\ddot{o}}rner$ are newly recorded in Korea; I. bimus Christiansen and Bellinger, and I. plumosus Bagnall. These species are collected from salt marshes near West Sea of Korea. The Korean materials of I. bimus agreed well with the original description by Christiansen and Bellinger from North America, in its peculiar body pattern, with two long ciliated setae on tibiotarsus of hind leg, multisetaceous lateral flap of ventral tube and the presence of a mucronal lateral seta. Isotomurus plumosus is also easily identified from other Isotomurus species by the peculiar colour pattern, and the presence of long maxillary lamella 1 and a mucronal seta.

  • The coastal vegetation of the southwestern coast of Korea was surveyed by the Braun-Blnquet's phytosociological sKDICe and its soil properties were also determined. Comparing with the coastal vegetation of Korea, Japan and Europe, the vegetation of this area could be classified into as follows; A. Thero-Salicornietea R. Tx. 1954(Salicor-nietum herbaceae assoc. nov.). B. Thero-Suaedetea Rivas Martwez 1979 (Suaedetum japonicae Miyawaki et Ohba 1966, Suaeda maritima commuity, Atriplici-Suaedetum maritimi Miyawaki et Ohba 1965, Suaeda asparagoided community) C. Asteretea tripolium Westhoff et Beeftink 1962 (Zoysietum sinice Ohba, Miyawaki et Tx. 1973, Limonietum tetragoni Miyawaki et Ohba 1969, Artemisietum scopariae assoc. nov., Aster tripolium community, Atriplex, gmelini community) D. Phragmitetea Tx. et Prsg. 1942 (Triglochietum maritimae assoc. nov., Carcetum scabrifoliae Miyawaki et Ohba 1969, phragmites communis community, Pyaceluretum latifolii Miyawaki et Okuda 1972, Scirpus fluviatilis community) E. Salsoletea komarovil Ohba, Miyawaki et Tx. 1973(Salsola komarovi community) F. Glehnietea littoralis ohba, Miyawaki et Tx. 1973(Caricetum pumilae assoc. nov., Meserschmidia sibirica community, Lysimachia mauri-tiana community Ishaemum anthephoroides community, Elymus mollis commuity, carex kobomugi community, Ixeris repens community) G. Viticetea rotundifoliae Ohba, Miyawaki et Tx. 1973 (Imperato cylindricae-Viticetum rotundifoliae ohba, Miyawaki ex Tx. 1973) and Opuntia ficus-indica var. saboten community. Among the soil properties, water potential seems to be one fo the most important factor on the distribution of the coastal plant community and it might be highly affected by water content in sand and salinity in low marsh.

  • Background: Organic carbon stored in coastal wetlands, which comprises the major part of oceanic "blue carbon," is a subject of growing interest and concern. In this study, organic carbon storage in coastal wetlands and its economic value were estimated using the raw data of 25 studies related to soil carbon storage. Data were collected from three tidal flats (one protected and two developed areas) and two estuarine salt marshes (one protected and one restored area). Bulk density, soil organic matter content, and standing biomass of vegetation were all considered, with Monte Carlo simulation applied to estimate the uncertainty. Results: Mean carbon storage in two salt marshes ranged between 14.6 and $25.5kg\;C\;m^{-2}$. Mean carbon storage in tidal flats ranged from 18.2 to $28.6kg\;C\;m^{-2}$, with variability possibly related to soil texture. The economic value of stored carbon was estimated by comparison with the price of carbon in the emission trading market. The value of US $ $6600\;ha^{-1}$ is ~ 45% of previously estimated ecosystem services from fishery production and water purification functions in coastal areas. Conclusions: Although our study sites do not cover all types of large marine ecosystem, this study highlights the substantial contribution of coastal wetlands as carbon sinks and the importance of conserving these habitats to maximize their ecosystem services.
