The factors of local disappearance and a plan of restoration fer Parnassius bremeri from Okchon-gun, Chungchongbukdo, Korea, were investigated. The population of this butterfly from Okchon-gun was much more abundant than the other areas of Korea in the past. But only two adults were observed in 1997 at this site and no more observation was made in 1998. So we considered that Parnassius bremeri is disappeared from this area. To know the factors of local disappearance of this species, we analyzed data of the monitoring from seven localities of Okchon-gun from 1990 to 1998 and also checked 252 specimens from this area by several collections. As a result of it, the habitat changes by recent road constructions and the frequent collecting activity around this area are shown as the factors for the local disappearance of this species. We are intending to establish the programs for restoration of Parnassius bremeri in Okchon-gun. Firstly, the breeding plan of this species was designed by investigation on life cycle. Secondly, the environmental conditions among seven localities were compared and the suitable places of the restoration were selected. The most suitable localities for restoration by this study were of two localities, Dongrakjeong and Jangwahri, which are considerd as highly successful breeding places in the view of growth condition of host plant.

The red-spotted apollo butterfly, Parnassius bremeri Bremer, 1864 (Lepidoptera: Papilionidae), is an endangered species in South Korea. Development and application of molecular markers to assess population genetics perspectives can be used as a basis to establish effective conservation strategies. In this study, we developed 12 microsatellite markers specific to P. bremeri using Illumina paired-end sequencing and applied the markers to South Korean populations to understand population characteristics. Genotyping of 40 P. bremeri individuals from three localities showed that at each locus, the observed number of alleles ranged from 6 to 22 and the observed and expected heterozygosities were 0.500-1.00 and 0.465 to 0.851, respectively. Significant deviation from the Hardy-Weinberg equilibrium was not observed in all loci studied. The population based $F_{ST}$ and $R_{ST}$ collectively suggest that at least the Samcheok population in northernmost Gangwon Province has a significant divergence from the remaining two populations (P < 0.01), and this result is also reflected in the forewing length. Further studies with an increased sample size will be necessary to draw robust conclusions and devise conservation strategies.

The 15,389-bp long complete mitogenome of the endangered red-spotted apollo butterfly, Parnassius bremeri (Lepidoptera: Papilionidae) was determined in this study. The start codon for the COI gene in insects has been extensively discussed, and has long remained a matter of some controversy. Herein, we propose that the CGA (arginine) sequence functions as the start codon for the COI gene in lepidopteran insects, on the basis of complete mitogenome sequences of lepidopteran insects, including P. bremeri, as well as additional sequences of the COI start region from a diverse taxonomic range of lepidopteran species (a total of 53 species from 15 families). In our extensive search for a tRNA-like structure in the A+T-rich region, one $tRNA^{Trp}$-like sequence and one $tRNA^{Leu}(UUR)$-like sequence were detected in the P. bremeri A+T-rich region, and one or more tRNA-like structures were detected in the A+T-rich region of the majority of other sequenced lepidopteran insects, thereby indicating that such features occur frequently in the lepidopteran mitogenomes. Phylogenetic analysis using the concatenated 13 amino acid sequences and nucleotide sequences of PCGs of the four macrolepidopteran superfamilies together with the Tortricoidea and Pyraloidea resulted in the successful recovery of a monophyly of Papilionoidea and a monophyly of Bombycoidea. However, the Geometroidea were unexpectedly identified as a sister group of the Bombycoidea, rather than the Papilionoidea.

Understanding the metapopulation structure and movement of a species are required for conserving the species. In this paper, migration patterns and connectivity of patches of a threatened butterfly, Parnassius bremeri Bremer, were postulated using the mark-release-recapture (MRR) technique in a habitat located in the mid-southern region of the Korean peninsula. A total of 194 individuals were captured (137 males and 57 females) and, of them, 93 individuals (73 males and 20 females) were recaptured during the MRR experiment. The migration analysis showed 23-150% immigration and 28-53% emigration. There were high correlations between the migrating individuals and the distance between patches, but there was no correlation between migrating individuals and patch size or between migrating individuals and the number of host plants. Consequently, the migration of butterflies occurred frequently between closer patches, while patch size and quantity of the food plant had minor effects on migration behavior. Additionally, males migrated more frequently than females. Analysis of the migration patterns of P. bremeri showed that the central patch played an important role on linking patch groups and more frequent migrations were monitored between nearby patches than between the remote patches. This study suggested that active migrations take place between the neighboring multiple patches and these are accelerated if there is a stepping-stone patch between them.

The present paper deals with a research of life form and vegetation of the plants extant in the habitat of endangered Parnassius bremeri in Uiseong, Gyeongsangbuk-do with a view to restore their habitat and create substitute habitats. The research found that there are a total of 130 vascular plants including 47 families, 96 genera, 113 species, 1 subspecies and 16 varieties. In terms of their life form, hemicryptophytes (H) is the majority of dormancy form with 41 species or 31.54%, while $R_5$ is majority of radicoid form with 72 species or 55.38%, gravitational disseminule form ($D_4$) is majority among the disseminule forms with 68 species or 52.31% and erect type (e) is majority of growth form with 57 species or 43.85%. Major constituents of the habitat are Sedum kamtschaticum, Selaginella tamariscina, Orostachys japonica, Arundinella hirta, Cymbopogon tortilis var. goeringii, Themeda triandra var. japonica, Carex humilis, Indigofera kirilowii, Imperata cylindrica var. koenigii, Festuca ovina, Artemisia capillaris, etc., all of species which are in the initial stage of succession and show simultaneously features characteristic of vegetation on the rock. In the habitat 1. Sedum kamtschaticum- Selaginella tamariscina community and Pinus densiflora community are distributed whereas, in the habitat 2. Sedum kamtschaticum-Selaginella tamariscina community, Sedum kamtschaticum-Carex humilis community, Sedum kamtschaticum-Cymbopogon tortilis var. goeringii community and Sedum kamtschaticum-Imperata cylindrica var. koenigii community are growing and in the habitat 3. Sedum kamtschaticum-Selaginella tamariscina community, Selaginella tamariscina community, Sedum kamtschaticum-Indigofera kirilowii community and Quercus acutissima community are seen distributed there, too. Typical of food plants growing in the habitat is Sedum kamtschaticum, found mostly in the rocky area and its surroundings. Absorption plants are those that usually bloom in the season when imagoes emerge. From the research, it becomes evident that the blooming season of Sedum kamtschaticum, obviously a food plant, corresponds exactly to the emergence timing of imagoes. Cirsium japonicum var. ussuriense, Rosa multiflora, Erigeron annuus, Spiraea prunifolia var. simpliciflora are found to belong to these plants.

This study was carried out to survey and confirm the occurring sites of Parnassius bremeri in Korea, and to investigate ecological characteristics to develop a mass rearing technique. In the field survey, adults were found in the two previously known sites in Gyungnam Province and another site was newly found in Samcheok, Gangwon Province. Emergence period of adults was from middle of May to middle of June. Oviposition took place on various material, including hostplant, debris, dead leaves, etc. Eggs were laid singly, up to 126.7 eggs per female. The egg-period was 221.3${\pm}$2.3 days, eggs were hatched from 11th to 22nd of January in the natural condition, and started to feed for about 10 days after hatching. Survival rate of the 1st larvae was 67.6%. Developing period of each instar in the insectary (25$^{\circ}C$, 75% RH, 16L:8D) was 11.2 days for the 1st instar, 7.3 days for 2nd, 12.8 days for 3rd, 16.2 days for 4th, and 18.2 days for 5th, and the pupal period was 21.3 days. The average longevity of adults was 26.2 days. Oviposition rate was higher in the natural condition with enough space to fly for 3♀ : 1 ♂ coupled, at least 3 ${\times}$ 3${\times}$4 m-sized room, than in smaller cage. In a comparison of the preference for visiting on sugar source, black sugar and fructose were effective.

Understanding the ecological complexity and habitat of a species are crucially important to conserve an endangered species. This study evaluated the patch network ecology of the endangered species $Parnassius$ $bremeri$. The results indicated that 188 individuals were captured and 220 were recaptured, respectively. The sex ratio of female: male was 42:146; males were four times more abundant than females. The average longevity of an adult was $3.93{\pm}3.93$ days (male, $4.0{\pm}3.9$; female, $2.5{\pm}1.0$ days); the maximum longevity was 14 days for males and 13 days for females, respectively. Therefore, the expected longevity of males was longer than that of females. The average emigration distance for the species was 377 m, and the maximum emigration distance was 1550 m. The analysis of patch connectivity and individual colonization revealed that the ideal distance between patches was about 300 m. Moreover, a >600 m patch distance decreased the colonization rate severely. We also observed higher immigration and emigration between patches that were clustered in close proximity. This leads us to conclude that a higher number of patches at a close distance is best suited for $P.bremeri$. We find these results to be crucial to determine a policy to protect and conserve this endangered species.

Establishing conservation programs to protect and maintain populations of endangered species are not only a global trend, but also a pursuit endorsed by the Korean Environmental Conservation Act. This study evaluates the feasibility of alternative habitat patches for the endangered butterfly Parnassius bremeri. A portion of habitat of P. bremeri is expected to be fragmented and damaged due to the scheduled construction of the Sangju-Yongduk Highway. A trans fer of the habitat patches of P. bremeri is also scheduled. In order to select an alternative habitat patch, the Mark-Release-Recapture (MRR) method was used to simulate a patch transfer model. The connectedness between habitat are as and the survival of local populations were evaluated for each candidate habitat. It was found that metapopulations with patch distances of <250m showed a 50% connectedness and survival rate in local populations. P. bremeri were expected to migrate at an average distance of 300m. In addition, P. bremeri formed a metapopulation that exhibited intimate patch dynamics that promoted persistence among these patches. Possible candidate habitats including those recommended by local governing bodies were evaluated along with habitats that may counter problems arising from the damage done to the original habitat and habitats that may have a compensatory value equal to that of the original habitat. Based on these criteria, Ansa-myeon township office was selected due to its high scores. This scoring was based on a consideration of a wide range of variables that mark a successful transfer of habitat. These include the amount of funding available, the governing bodies of the possible alternative habitat, and the Expected collaborative effort of local citizens. This decision was collaborated on by incorporating the expertise of various fields of study including biology, ecology, biogeography, ecological engineering, landscape architecture, and social sciences. Therefore, it is suggested that in order to evaluate an alternative habitat for organisms, many social issues as well as ecological issues must be considered.

National parks and other protected areas often do not adequately protect national biodiversity because they were originally created for socio-economic and/or aesthetic values. The Korean government has committed to expanding the extent of protected areas to fulfill its commitments to the Aichi Biodiversity Convention. To do so, it is necessary to quantify the current levels of biodiversity representation within existing protected areas and to identify additional conservation needs for vulnerable species and ecological systems. In this study, we assess the proportion of species ranges found in South Korea's protected areas, for the species documented in the 3^rd National Ecosystem Survey. We modeled the range distribution of 3,645 species in the following taxonomic groups; plants (1,545 species), mammals (35), birds (132), herptiles (35), and insects (1,898) using the MaxEnt species distribution model and calculated how much of each species' range is within protected areas. On average, 17.4% of plant species' ranges are represented in protected areas, while for mammals and insects an average 12.0% is currently conserved. Conservation representation for herptiles averages 9.3%, while it is 8.6% for birds. Although large proportions of species that have restricted distributions should be represented in protected areas, 17 plant species, two insects (Parnassius bremeri and Lasioglossum occidens), and one bird species (Phylloscopus inornatus) with ranges smaller than 1,000 ㎢ have less than 10% of their ranges within protected areas. Establishing specific conservation goals such as the protection of endangered species or vulnerable taxonomic groups will increase the efficiency of the biodiversity conservation strategies. In addition, lowland coastal areas are critical for biodiversity conservation because the protected areas in South Korea are mainly composed of high mountainous areas.
