To select tolerant species among the Korean major woody plants for restoring disturbed ecosystems by air and soil pollution, we transplanted the seedlings of 56 species in control and polluted sites within Yeocheon industrial complex area, and compared their aboveground growth characteristics such as total branch length, total leaf weight, and maximum photozynthetic rate. Tolerant species growting better in polluted site than in control site was Quercus variabilis, Pinus thunbergii, Q. aliena, P. densiflora, Styrax japonica, Alnus firma, Celtis sinensis, Elaeagnus umbellata, Q. serrata, japonica, Sorbus alnifolia, and Q. acutissimia in local tree occuring within polluted area group (80%), Ailanthus altissima in street tree group (20%), Populus tomentiglandulosa and A. hirsuta var. sibirica in fast growing tree group (50%), Acer ginala and Abies holophylla in late successional tree group (20%), Betulla platyphylla var. japonica, Acer truncatum, A. palmatum, Syringa dilatata, and Rosa multifora in garden tree group (38%), and Q. rubura, and Robinia pseudoacacia in foreign restoring tree group (20%), respectively. The remaining plant species, 37 species (57% of total species), were classified into sensitive species to pollution. Those tolerant species can be utilized for restoration of the degraded ecosystem in this polluted area.

The purpose of this study was to develop a Korean thermality index (KTI) based on the distribution patterns of benthic macroinvertebrates according to altitude and latitude. Analyzing seasonal data (4,853 sampling units) surveyed and collected during 2007 ~ 2011 at 846 sites in South Korea, we estimated thermal valency, thermal value and indicator weight value of 208 species. Among them, 40 species in 6 orders (Decapoda 1 species, Collembola 1 species, Ephemeroptera 5 species, Plecoptera 17 species, Diptera 3 species, Trichoptera 13 species) were selected as the candidate indicator species sensitive and vulnerable to warmth along with climate change. KTI and Benthic macroinvertebrate index (BMI) were tested at three clean streams (Hangye stream, Buk stream and Bangtae stream). KTI showed significant differences according to altitude and water temperature whereas the saprobity index BMI showed little differences. This result means that KTI can be applicable to assess the impact of water temperature independently of organic pollutants.

Chrysosplenium aureobracteatum Y. I. Kim & Y. D. Kim (Saxifragaceae) is a recently described endemic species growing in the central part of the Korean peninsula. It requires constant monitoring for conservation due to its limited distributions. There is also a need for molecular markers for proper assessments of the genetic differentiation of C. aureobracteatum from species morphologically similar to it. In this study, we developed microsatellite markers that can be used to evaluate the genetic diversity of this species, representing fundamental data with which to conserve the natural populations of the species. A total of 17 expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed by the Illumina pair-end sequencing of the transcriptomes of C. aureobracteatum. These markers were successfully applied to populations of C. aureobracteatum and to its most closely related species, C. barbatum, revealing high polymorphism in both species. The EST-SSR markers developed in this study were proven to be useful not only to monitor the population genetic structure of C. aureobracteatum for conservation purposes but also to study the genetic delimitation of the species from species closely related to it.

Climate change is affecting the evolutionary trajectories of individual species and ecological communities, partly through the creation of new species groups. As population shift geographically and temporally as a result of climate change, reproductive interactions between previously isolated species are inevitable and it could potentially lead to invasion, speciation, or even extinction. Four species of abalone, genus Haliotis are present along the Korean coastline and these species are important for commercial and fisheries resources management. In this study, genetic markers for fisheries resources management were discovered based on genomic information, as part of the management of endemic species in response to climate change. Two thousand one hundred and sixty one single nucleotide polymorphisms (SNPs) were discovered using genotyping-by-sequencing (GBS) method. Forty-one SNPs were selected based on their features for species classification. Machine learning analysis using these SNPs makes it possible to differentiate four Haliotis species and hybrids. In conclusion, the proposed machine learning method has potentials for species classification of the genus Haliotis. Our results will provide valuable data for biodiversity conservation and management of abalone population in Korea.

An equilibrium analysis was carried out to determine principal species of heavy metals in waste incineration and their behaviors with variation of temperature, chlorine concentration, excess air ratio, and C/H ratio. The waste was assumed as a compound of hydrocarbon fuel, chlorine, and metals. Calculated results showed that the most important parameter to determine the principal species was temperature. Chlorine concentration also affected on mole fractions of the principal species. Generally principal species at high temperature were chlorides while there were some metals of which principal species were oxides. At low temperature mole fractions of the principal species increased, but at high temperature mole fractions of some metal species decreased. C/H ratio of the hydrocarbon fuel and excess air ratio had little effect on mole fractions of the metal species, compared to the temperature and chlorine concentration.

An equilibrium analysis was carried out to determine principal species in the incineration of hazardous waste, which was assumed as a compound of hydrocarbon fuel, chlorine, sulfur, and heavy metals, and their behaviors with variation of temperature, chlorine and sulfur concentrations. Calculated results showed that the most important parameter influencing the principal species was temperature. Chlorine concentration affected on mole fractions of the species, especially at high temperature. Existence of sulfur had a significant effect on the species at low temperature, regardless of surfur concentration. Generally, principal species at high temperature were chlorides and oxides, while the principal species at low temperature were sulfides. As temperature increased, mole fractions of the principal species increased at low temperature, however, mole fractions of some metal species decreased at high temperature.

Egg incubation periods of 14 species of plecoptera were examined at $10^{\circ}\;{\sim}\;11^{\circ}C$, $15^{\circ}\;{\sim}\;16^{\circ}C$, $20^{\circ}C$, and $23^{\circ}C$ under dark conditions. The total effective temperature (TET) was calculated by multiplying mean egg incubation days and water temperature of incubation periods. The relation between the TET and the incubation temperature was used to compare the life cycle of respective species. Perlodid species had higher TET values with a positive relation to incubation temperature than those of other species. Perlid species had low TET values in the 14 species with negative to variable relation, and Chloroperlid species showed variable to positive relations to incubation temperature. These results suggest that the relation between the TET and the water temperature reflected on their habitat of respective species.

Moth diversity of Mt. Duryunsan and its neighboring area, Haenam, Jeonnam, collected from 2001 to 2004 is presented. A total of 498 species were identified and a logarithmic equation to the species accumulation data provided a good fit $(R^2=0.98;$ y=218.52 LN (x)+161.88), predicting that 665 moth species are expected after ten years of collecting. Yearly species accumulation data showed that the moth faunal composition was changing by the appearance and disappearance of species: $94\~119$ species were newly collected in the following years; and $32\~90$ species were not collected in the following years. The fourth year was the most species-rich with 250 species. The need of long- term research of speciose insect taxa is briefly discussed.
