지구상에 서식하고 있는 포유강(Class: Mammalia), 박쥐목(Order: Chiroptera)에 속하는 박쥐류는 1,000여종에 이르는 것으로 알려졌으며, 포유류 중에서 1/4을 차지하고 있으며, 그 2/3는 곤충류를 포식하는 식충성을 지니고 있다. 우리나라에 서식하고 있는 박쥐류는 관박쥐과(Family:Rhinolophidae) 2종, 애기박쥐과(Family: Vespertilionidae) 28종, 큰귀박쥐과(Family: Molossidae) 1종으로서 총 31종이며, 모두 식충성 동물이다. 흡충류라고 하는 것은 편형동물문에 속하는 기생성 동물의 한 군으로서, 항온동물의 장이나 그 밖에 조직에 기생하는 것은 모두 하나 또는 두개 이상의 중간숙주를 필요로 하는 이생 흡충이다. 제1중간숙주는 고둥이지만 제2중간숙주는 여러 가지 변온동물로서 그 대부분은 생활사에 있어서 수서 생활을 하는 시기가 있는 것에 한정되지만 이는 제1중간숙주의 체내에서 형성된 꼬리유충이라고 하는 흡충류의 유생이 보통 물 속을 헤엄쳐 다니다가 제2중간숙주에 침입하게 된다. 박쥐류는 여러 가지 땅강아지나 개똥벌레를 포식하기 때문에 이들 유생이 물 속에서 흡충류의 피낭유충에 감염되었을 경우 박쥐류가 흡충류의 종숙주로서 적합하면 그 체내에서 피낭유충이 장에서 탈랑하여 드디어 성충으로 된다. 만일, 감염된 수서 곤충의 유생이 우화되면 그 유생 시대에 감염된 피낭유충이 그 숙주의 변태와는 상관없이 그 기생이 이어져 적당한 종숙주에게 섭취되기를 기다리게 된다. 우리나라에 있어서 박쥐류에 기생하는 흡충류에 관한 조사 연구는 일찌기 도쿄문리과 대학 동물학 연구실의 Ogata(1938)에 의하여 이루어진 이래 경성제국대학 의학부의 Park(1939a,b)과 후쿠오까대학 의학부의 Kifune et al.(1983, 1997)이 있을 뿐 우리나라 학자에 의한 연구 보고는 접할 수 없는 형편이다. 그럼으로, 우리나라 학자도 이에 관한 더욱 더 깊은 관심을 가져야할 것으로 생각하는 바 이에 지금까지 보고된 자료를 종합, 검토하여 기술하고자 한다.

This study was carried out to investigate the flora of Mt. Biseul. The vascular plants collected 10 times(from May 2006 to October 2007) were identified as 468 taxa in total, including 89 families, 302 genera, 397 species, 1 subspecies, 59 varieties and 11 forms. Korean endemic plants of this area were identified as 17 taxa including Thalictrum uchiyamai, Coreanomecon hylomeconoides, Lonicera subsessilis, etc.; the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as one taxon including Aconitum austrokoreense; the Office of Forestry-designated rare & endangered plants were identified as 6 taxa including Viola albida, Lloydia triflora, Streptopus ovalis, etc.; the naturalized plants were identified as 34 taxa, and their naturalization ratio and urban index were found to be 7.3%, and 12.2% respectively. This study newly identified about 160 taxa of the plants, among which 17 taxa were newly added to the list of naturalized plants, such as Phytolacca americana, Dicentra spectabilis, Lepidium apetalum, Medicago lupulina, Euphorbia supina, Ambrosia artemisiifolia, Cosmos bipinnatus, Crassocephalum crepidioides, Galinsoga ciliata, Rudbeckia bicolor, Sonchus oleraceus, Tagetes minuta, Taraxacum officinale, Chloris virgata, Festuca arundinacea, Lolium perenne, Tradescantia reflexa, etc. There existed many kinds of plants resources having conservational value like Aconitum austrokoreense etc. in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.

The climate change affects the growth and development of weeds as well as the outbreak of weeds. Especially, the occurrences of problematic paddy weeds due to climate change might cause the difficulties in weed control. This study therefore, investigated the current dominance and distribution of paddy weeds. As a result of the study on paddy weeds in northern Gyeonggi-do, there were total of 65 taxonomy groups including 23 family, 41 genus, 57 species, 7 subspecies and 1 variety. Among all the plants, 46 species were annual plants and 16 were perennial plants. Echinochloa crus-galli was the highest in importance analysis and the followings were in order of Ludwigia prostrate and Lemna paucicostata. The similarity of different paddy weeds in different regions observed through TWINSPAN analysis was distinguished by Fimbristylis miliacea, Rotala indica and Cyperus flaccidus. Regional differences shown in CCA analysis using weed species and soil environment revealed that Gimpo-si and Namyangju-si has difference soil and weeds, which are features that distinguished them from other regions. In northern Gyeonggi-do the result of paddy weed research showed the interregional difference not in dominant weeds but in distribution species.

In the marine area, the salt concentration in the soil increases, and the inland heavy metal pollution increases the damage of plants. In the inland industrial development area, researches on the genetic resources of plants together with the heavy metal accumulation of Co, Ni, Zn, and so on are required. Both of these problems have caused scientists to work hard to find plants that are likely to cause stress in plant roots. In this study, seeds of Arabis stelleri var. japonica collected near the shore were used for germination. The growth and development and tolerance of both Arabis and Arabidopsis seeds were investigated under laboratory culture conditions. As a result, Arabis showed resistance about 3 times in 250 mM nickle and cobalt, and more than 4 times in 1 mM zinc when compared to Arabidopsis. The tolerance of Arabis to Na salts increased by 20% or more at 50 mM concentration and Arabis was resistant to heavy metals and salt concentration. The accumulation of Na ions in the body was measured as a preparation for studying the intracellular mechanism. As a result, it showed a further decrease in resistance to ground water roots. It is considered that the activity of the exporting gene is important rather than the mechanism of accumulation.

To understand vegetational characteristics of abandoned paddy terraces (APTs), species composition and plant species richness of APTs were compared with those of other natural- and constructed wetlands (NWs and CWs, respectively). Based on frequency of major vegetational components, Phragmites japonicus was more common in APTs (23.9%) than NWs (10.8%) and CWs (10.8%), whereas P. australis was less frequent in APTs (18.3%) than NWs (43.1%) and CWs (35.4%). Typha orientalis was common only in APTs (19.7%), whereas T. angustifolia was relatively common in NWs (21.5%) and CWs (32.3%). In addition, some wetland obligate species such as Leersia japonica, Oenanthe javanica, and Sium suave were frequently found only in APTs. In particular, APTs showed higher plant species richness ($6.3{\pm}2.2\;species/m^2$) than NWs ($4.9{\pm}1.8\;species/m^2$) and CWs ($3.9{\pm}1.3\;species/m^2$). APTs exhibited not only their distinctive vegetational characteristics but also higher ecological value in terms of plant species richness. Further attention on APTs as valuable biotopes supporting diverse plant species and continuous effort for management and conservation are needed more.

Biopolymer based on microbial ${\beta}$-glucan and xanthan gum is a rising geotechnical material that can enhance the cohesion between soil particles and consequently reduce soil erosion. Recently, biopolymer is proposed to utilize for the riverbank strengthening. As an effort of the ecological assessment of biopolymer application in civil engineering, this study examined the effects of biopolymer on seed germination and growth of nine plant species inhabiting in the Korean riverside. Responses of above-ground growth to the biopolymer differed among plant species. One species grew less but others maintained their growth when plants were grown in the soil with biopolymer. In contrast, root grew more vigorously and root/shoot ratio decreased in the biopolymer across testing plant species. These results indicate that biopolymer application on the river bank likely stimulate root growth of native plant species, which, in turn, possibly reinforces riverbank. Species specific responses of above-ground growth implies that ecological effects of biopolymer application would depend on the species composition of the ecosystem.

A field survey was conducted from June 2005 to September 2007 to explore changes of the vegetation and life form in the man-made Wetland along the Sinpyeongcheon for 3 years after its creation. A total of 20 species including 14 families, 18 genera, 15 species and 5 varieties were planted in the Wetland which was completed in 2004. Divided by life form of the planted species, a prevalent 65% of them was composed of perennation while 4 species of woody plants i.e. Fraxinus rhynchophylla, Salix glandulosa, Camellia japonica and Nandina domestica were planted there, too. The 3-year study revealed that hydatophytes (HH) scored the biggest increase in number, followed by slight increase in the number of microphanerophytes (M), megaphanerophytes (MM), chamaephytes (Ch), nanophanerophytes (N), perennial plants (H), etc., featuring generally a similar tendency for the whole period of study. The change in vegetation area increases in the area of Typha angustata, Phragmites japonica, Phragmites communis, etc. but a sharp decrease in the area of communities for other planted species. In terms of change in the area for planted species by their life form, hydatophytes (HH), HH Th (Th(w)) reported gradual increase while microphanerophytes (M), geophyte (G), and nanophanerophytes (N) continued to record a decrease. In conclusion, selection of plants to be planted turns out to play a vital role in molding the destiny of a man-made Wetland. It seems therefore extremely important to investigate the flora, and life and growth forms of the plants planted in the man-made Wetland in an effort to choose the species that can adapt themselves to the environment from the early phase on, contributing by thus to stabilization and diversification of the damp ground in line with the progression of their succession.

This study was conducted to provide data for the maintenance of the Corylopsis coreana community within the Hallyeohaesang National Park. Survey site of Corylopsis coreana community was located at a valley, which composed of over 60% exposed rock. As this result, much of the species was damaged or washed away due to the water flow from rainfall. The tree layers dominant species were Quercus serrata and Pinus densiflora. while the subtree layers dominant species were Corylopsis coreana, Acer pseudosieboldianum, Sapium japonicum, Chamaecyparis obtusa and Cornus kousa etc. The shrub layers dominant species were Callicarpa japonica and Smilax china etc., and herbaceous layers dominant species were Disporum smilacinum etc. Increased precipitation and rainfall days were observed from May to September in this valley during 2008~2010, which likely increased soil erosion and damage. Because water flow pattern was dispersed the Corylopsis coreana seed and the soil floor was shallow, and population of Corylopsis coreana seedlings were diminished.
