A vegetation survey of the native pasture was conducted in Cheju from July to September, 1980. The purpose of this investigation were, to determine the botanical composition of the native pasture and to estimate how they can be improved to the feed resources of livestock industry. The results obtained are summarized as follows: 1. Grass species existed in native pasture were 64 species with Pwceae 13, Fabaceae 8, Carduacea 12 and other 31. Most of them were identified as perennial grasses. 2. Botanical composition of major grass species were Imperata cylindrim 32.7 %, Pteridium aquilinum 18.9 70, Miscanthus sinensis 8.4 %, and Arternisia japonicn 2.8 % respectively. 3. The average dry matter yield of forage taken on the native pasture was 383 kg per 10a and these yields were increased as the growing stages progressed. 4. Seasonal distribution of edible plants were increased as the growing stages progressed.

The knowledge of native wild mushrooms traditionally using in Jeju Island, that have specific native environment and various biodiversity, was investigated. From Jeju and Seogwipo cities including 7 provinces 4 locals, so total 50 villages, data was collected in the entire area and voice of the 93 elderly people between the age of fifty and ninety were recorded. As a result, total 23 native wild mushrooms were used in which 2 species were poisonous mushrooms, 7 species were medicinal mushrooms, 2 species was used for folk religion, 2 species were not used for living but for attention and 12 species were edible mushrooms. Also, a total of 267 cases of traditional knowledge was collected, in which 197 cases were about edible mushrooms for 12 species, 43 cases were about poisonous mushrooms for 2 species, 16 cases were about medicinal mushrooms for 7 species. Interestingly, the fortune for agriculture was told depending on spore mass release of Cyathus stercoreus which grows in animal feces and compost. It is considered as the distinctive traditional knowledge of Jeju Island.

Green roof's performance in reducing stormwater runoff has been reported by numerous studies. Nonetheless, the roles of low growing vegetation in influencing stormwater runoff reduction on green roofs have been greatly overlooked. This paper describes an experiment investigating the influence of low growing vegetation in the reduction of tropical stormwater runoff on extensive green roofs. Three types of locally occurring native vegetation and one non-native Sedum species were selected (fern, herb, grass and succulent) for the experiment. Stormwater runoff reduction performance from different low growing species was done by measuring excess water runoff from the simulated green roof modules. The results show significant differences in stormwater runoff reduction from different types of vegetation. Fern was the most effective in reducing stormwater runoff, followed by herb, Sedum and grass. Vegetative characters that are found to attribute towards the performance of stormwater runoff are rooting density, structure, density, leaf type, and vegetation biomass.

Arbuscular mycorrhizal fungi were observed in Botrychium ternatum native in Korea. The partial small subunit(SSU) of ribosomal DNA gene from the fern roots was amplified with primers AM1/NS31. Nucleotides sequence analysis of the clones revealed that two fragments were close to Glomus proliferum and G. sinuosum. The other three DNA fragments were close to those of G. proliferum with the relatively low similarities($92{\sim}95%$) and speculated to be originated from three different species of Glomus(GLA006, GLA016, and GLA032). Five different nucleotide sequences close to three AM fungal species were found in the roots of B. ternatum native in Korea.

Present study was performed to survey infection status of digenetic trematode metacercariae in 2 alien fish species, Micropterus salmoides (largemouth bass) and Lepomis macrochirus (bluegill), in 2 rivers draining Chungcheongbuk-do, Republic of Korea. A total of 107 largemouth bass and 244 bluegills were caught in Daecheong-ho (ho=lake) and Musim-cheon (a branch of Geum-gang), in Chungcheongbuk-do April-July 2015. Additionally, 68 native fish of 5 species, i.e., Zacco platypus, Hemibarbus longirostris, Carassius auratus, Pseudogobio esocinus and Puntungia herzi, were caught from the same water bodies. All of the fish collected were examined by artificial digestion method. The metacercariae of Centrocestus armatus, Clinostomum complanatum, Metagonimus sp. and Diplostomum spp. were detected from 4 out of 5 native fish species in Daecheong-ho. However, any metacercariae were not found from 87 M. salmoides and 177 L. macrochirus in Daecheong-ho. In Musim-cheon, metacercariae of Exorchis oviformis and Metacercaria hasegawai were detected from 78% Z. platypus and 34% L. macrochirus, but any metacercariae not found in M. salmoides. We report here that the 2 alien fish species were less infected with the metacercariae than the native ones. Surveys on the metacercariae in the alien fish species in geographically various rivers should be undertaken for better understanding on the role of alien fish species in the trematode infections in Republic of Korea.

The saga of Megascolides orthostichon (Schmarda, 1861)-the first native worm described from Australasia-continues as its type-locality is unequivocally returned from Hobart, Tasmania to Mt Wellington, Auckland where a brief survey failed to unearth it. Since it has not been seen for 150 yrs, it may qualify under NZTCS or IUCN classification as 'Nationally Critical' if not 'Extinct'. New reports are for exotic Megascolecidae Anisochaeta kiwi sp. nov. and A. kiwi mihi sub-sp. nov. plus addition to the NZ faunal list of Australian Anisochaeta macleayi (Fletcher, 1889) that, due to its wide distribution in Australia and now New Zealand, may be a candidate model-species suitably resilient for eco-toxicological culture and monitoring. For holarctic Lumbricidae, new records are of Dendrobaena attemsi (Michaelsen, 1903) and the Murchieona muldali (Omodeo, 1956) morph or subspecies of M. minuscula (Rosa, 1906), neither lumbricid previously uncovered in Asia/Australasia. Also found for the first time outside its East Asian homeland is Eisenia japonica (Michaelsen, 1892) (which is compared to Japanese E. japonica hiramoto sub-sp. nov. and to E. anzac Blakemore, 2011). Records of these exotics plus recent new native species described by the author-including two, Rhododrilus mangamingi and Deinodrilus orcus spp. novae, herein-raise the numbers of megadriles known from New Zealand to 228 (sub-)species in five families. Preliminary mtDNA COI sequence barcodes are presented. Genus Tokea Benham, 1904 is revived on its lack of dorsal pores, losing or gaining some species with Megascolides M'Coy, 1878. An updated checklist of all 228 New Zealand taxa is appended.

Moss is used as an important material in indoor landscaping as well as outdoor landscaping. Moss is vivid green during growth and excellent in ornamental value. But when temperature drops, moss stops growth, turns brown or loses its ornamental value. In the present experiment, for the purpose of classifying native mosses according to the growth response to low temperature, the temperature of the plant growth chamber was set to 15℃/5℃ (16h/8h, day/night) and 5℃ (24h) for 8 weeks using nine native moss species. Thereafter, the temperature of the plant growth chamber was set to 20℃, and then the changes of moss block area and moss color were measured. The changes of moss block area and moss color were measured using a Photoshop program, after each moss block was photographed. As a result, Atrichum undulatum (Hedw.). Beauv., Etodon luridus (Griff.) A. Jaeger, Bachythecium plumosum (Hedw.) Schimp, Plagiomnium cuspidatum (Hedw.) T.J. Kop, and Hypnum plumaeforme Wilson showed a small decrease in moss block area at low temperature, and their recovery were the fastest at 20℃. These three species had higher green values at low temperature compared to other species, and the greenness increased rapidly at 20℃. On the other hand, Atrichum undulatum (Hedw.). Beauv., Marchantia polymorpha L., and Thuidium cymbifolium (Mitt.) A. Jaeger showed the smallest block area at low temperature and the lowest recovery even at 20℃. Their green values also decreased significantly at low temperature, and maintained low green value even at 20℃. These results showed that these three moss species are sensitive to low temperature. The remaining Myuroclada maximowiczii, Plagiomnium cuspidatum, and H. erectiusculum showed moderate responses to low temperature compared to other six species of mosses.

Pathogen introductions associated with aquatic invasive species threaten ecosystems and biodiversity worldwide. Bigheaded carps (BHC), including Silver Carp Hypophthalmichthys molitrix, Bighead Carp H. nobilis, and their hybrids, are prolific, invasive pests in central US rivers. However, little is known about pathogen effects on invading BHC or how BHC affect the disease risk profile for native fishes in receiving ecosystems. We therefore conducted, from May 2013-December 2014, a systematic pathogen survey for BHC and native fishes in the Wabash River watershed, Indiana, USA. We found Pseudomonas fluorescens, P. putida, and Salmonella enterica DNA in BHC as well as native fishes, although none of these bacteria were exclusively present in BHC. DNA from other bacterial taxa was detected only in native fishes and Common Carp Cyprinus carpio. No gastrointestinal helminths were detected in BHC, although they were common in most native fishes examined. We also conducted in vitro studies on BHC tissues (skin, gill, fin, and fry) and found high sensitivity to Largemouth Bass virus, viral hemorrhagic septicemia virus, and infectious pancreatic necrosis virus. We conclude that BHC are not heavily burdened by bacteria, viruses and parasites in the invaded study ecosystems, although they do harbor native bacteria and show potential for high sensitivity to endemic viruses.

Non-native flora of the Ulleung island, located in the eastern part of South Korea, was surveyed as 54 taxa with 16 families, 35 genera, 53 species and 1 variety. Considering the geographical distribution aspects of the island, the flora of the island showed more closely related with Korean Peninsular than Japan. Poaceace (28%) and Asteraceae (24%) represents more than 50% of the non-native flora in Ulleung island, meaning that they have an advantage of seed dispersal and adaptation to new environments. Ulleung island is comparatively small island of vulnerable to the attack of invasive alien plants but presently, it has the least number of non-native plants than other areas in South Korea. Therefore, we need to take much interest in prevention and mitigation of non-native plant in the future.
