The 2015 version of the bibliographic checklist of Korean spiders from the first checklist by Paik and Kim (1956) is presented, together with a complete bibliography of relevant Korean araneological literature. A total of 620 publications during 1907-2015 including original description on the Korean spiders and records of taxonomic description were critically reviewed. Records only from locations within the present borders of South Korea are listed. A total of 748 spider species of 271 genera belonging to 46 families are confirmed to exist in Korea. Twenty one species, whose distribution or existence within the Korean border are uncertain and lacked valid records, are excluded from the present list pending critical validation. Four spider species endemic to North Korean are listed separately from the present list. One genus, Joopilia Chae and Sohn, 2013 and 2 species, Joopilia jooplis Chae and Sohn, 2013 and Dolomedes jirisanensis Kim and Chae, 2012, which had no designated type species and no diagnosis, are cited as nomina nuda. New synonyms of 15 previously described spider species are proposed. Based on their zoogeographical distribution, the Korean spider fauna was found to be influenced by the northern species, including 36 Holarctic and 72 Palearctic species (14.5% of the total species). Korean endemic species include 160 species (21.5% of the total species). Korean indigenous spiders are also distributed in neighboring countries: 318 species in Russia (42.7%), 460 in China (61.7%), and 488 in Japan (65.5%).

588 taxa of vascular plants including 121 families, 399 genera, 510 species, 67 varieties, 2 subspecies, 7 forma, and 2 hybrid species were investigated in Mt. Cheonsung. Among them, 116 species were newly added in this research. The area for Gyeongbu High-speed Railway passes Mujechi 3, 4, 5, and 6 and Daeseongsa around the wetlands were investigated 6 species of rare and endangered plants, 9 species of endemic plants and 37 species of special flora plants in Mt. Cheonsung. Appear due to the construction of the Gyeongbu High-speed Railway vegetation changes, especially about the impact of wetland plants for long-term monitoring is expected to need. Moreover, plant preservation plan about water source change in upper wetland should be established.

A total of 1,496 rodents and insectivores were live-trapped at Yeoncheon-gun (n = 351), Paju-shi (804), and Pocheon-gun (343), Gyeonggi-do (Province), and examined for intestinal helminths, including Neodiplostomum seoulense, seasonally from December 2004 to September 2005. Six species of rodents, including Apodemus agrarius (1,366), Mus musculus (32), Micronytus fortis (28), Eothenomys regulus (9), Micronys minutus (6), and Cricetulus triton (3), and 1 species of insectivores Crocidura lasiura (54) were collected. A total of 321 adult N. seoulense were collected from 19 (1.4%) A. agrarius. The worm burden ranged from 1 to 101 per A. agrarius (mean; 16.9). No N. seoulense was observed in other rodent or insectivore species examined. The infection rate during autumn (4.5%) was higher than those during spring (0.8%), summer (0.8%), and winter (0.5%). The average number of N. seoulense in infected A. agrarius was the highest in spring (66.0 specimens), followed by autumn (15.2), winter (4.5), and summer (3.3). This study first confirms that A. agrarius is a natural definitive host for N. seoulense, and demonstrates that the infection rates and intensities vary seasonally and geographically.

The small intestines of 6 species of rodents and 1 species of insectivore were examined seasonally for Plagiorchis muris infection in 3 different localities in northern Gyeonggi-do (Province), near the demilitarized zone (DMZ). A total of 1,496 animals, including 1,366 Apodemus agrarius, 54 Crocidura iasiura (insectivore), 32 Mus musculus, 28 Micronytus fortis, 9 Eothenomys regulus, 6 Micronys minutus, and 3 Cricetulus triton, were live-trapped at Yeoncheon-gun (n = 351), Paju-shi (804) and Pocheon-gun (343) at 3-mo intervals from December 2004 to September 2005. A total of 1,647 P. muris were collected from 72 (5.3%) A. agrarius. The infection rate was the high-est in Pocheon-gun (8.2%), followed by Yeoncheon-gun (5.0%) and Paju-shi (4.2%). A higher infection rate was observed in A. agrarius captured during September (19.4%) than those captured during December (3.0%), June (2.6%), or April (0%). However, the worm burden was the highest in June (av. 32.1/animal), followed by September (24.7), December (4.0), and April (0). None of the other animal species were found infected with P. muris. The results reveal that A. agrarius is a natural definitive host for P. muris, and infection rates and worm burdens vary seasonally and geographically.

Here, we have described and illustrated a new endemic species of Scutellaria orthocalyx. This species, from Jeju-do, Korea, is clearly distinguished from other species of Scutellaria orthocalyx, especially its close relative, Scutellaria orthocalyx has relatively many leaves further down the stem. The shape of leaves begins linear and becomes lanceolate. Scutellaria orthocalyx can also have long shaped leaves on the upper part. Scutellaria baicalensis by linear, terete, fistulous and long leaves. A index to these species is provided.

Fish fauna of 13 sites in a main channel and its tributaries of the Taehwa River and 9 Sites of other headwater streams in the Ulsan area (Mt. Gaji) were investigated from February 1999 to October 2000. All sites were the 1st to 5th order streams in the Ulsan area, and 10 sites (45.5%) were intermittent streams. A total of 2,695 flsh specimens were collected and classified into 14 families and 44 species. Cyprinidae accounted for 40.9% (18 species) of the total fish species collected and 68.4% (1,845 ind.) of the total abundance. Subdominant families were Cobitidae (6 species; 78 ind.), Gobiidae (5 species; 240 ind.), and Gasterosteidae (2 species: 128 ind.). Zacco temmincki (RA 23.0%, 14 sites) was the dominant species; subdominant species were Moroco oxycephalus (20.2%, 11 sites), Zacco platypus (8.0%, 10 sites), Mugil cephalus (5.2%, 3 sites). Among the total species, 8 species were endemic species to Korea. The dominant Korean endemic species was Squalidus chankaensis tsuchigae (53.6% of Korean endemic species) and subdominant species were Iksookimia longicorpa (20.5%), and S. japonicus coreanus (6.6%) . Due to the intermittent nature of streams in the Ulsan area, a conservation program of nsh fauna is strongly needed.

Subalpine zone is geographically vulnerable to climate change. Forest vegetation in this zone is one of the important basic indicator to observe the influence of climate change. This study was conducting phytosociological community classification and endemic-rare plants investigation based on vulnerable species to climate change at the subalpine zone, Mt. Jiri. Vegetation data were collected by 37 quadrate plots from March to October, 2015. In order to understand the species composition of plant sociological vegetation types and the ecological impacts of species, we analyzed the layer structure of vegetation type using important values. Vegetation type was classified into eight species groups and five vegetation units. The vegetation types can be suggested as an indicator on the change of species composition according to the future climate change. There were 9 taxa endemic plants and 17 taxa rare plants designated by KFS(Korea Forest Service) where 41.2% of them were the northern plant. Endemic-rare plants increased as the altitude of vegetation unit increase. Importance value analysis showed that the mean importance value of Abies koreana was highest of all vegetation units. Based on analysis of each layer, all units except vegetation unit 1 were considered to be in competition with the species such as Quercus mongolica and Acer pseudosieboldianum. The results of this study can be a basic data to understand the new patterns caused by climate change. In addition, it can be a basic indicator of long-term monitoring through vegetation science approach.
