In May to July 2019, ovate-leaf atractylodes seedling and plant with Damping-off symptoms were observed in farmer field at Sangju and Mungyeong, Korea. Seven fungal isolates have been retrieved from diseased root tissue and identified as Rhizoctonia solani AG-5 based on morphological and molecular characteristics. To the best of our knowledge, this is the first report on damping-off of ovate-leaf atractylodes caused by R. solani AG-5 in South Korea.

This study is written with a purpose to foresee the changes of way of life in the 21st century trough recognizing an environment based on a correct ecological world-view and to create environmental design of seeing the nature and humans as one organism. This study is focused especially in environmental design and written generally based on urban ecology human ecology cultural ecology and plant ecology with this multi-interdisciplanary approach,. To understand meaning of ecosytem by considering the theory of ecology for ecological approach of the environmental design and to grope for possibility of applying environmental design by considering what to analyze and how to differenciate concept for ecological environmental plan from the mechanical design. Through this study it was realized that the ecological design starts from the recognistion of seeing the humans and nature as a one and form being aware of signficance of all the living things in our surrounding environment.

Problems and improvement plan in ecological pathways created by Environmental Impact Assessment(EIA) were found based on 504 expost environmental impact survey reports submitted to the National Institute of Ecology in 2016. A total of five improvement plans have been proposed. First, the concept and composition principle of ecological pathways should be unified. Second, Guidelines for consultation on the EIA should be provided for each stage to be applied on-site. Third, if ecological pathway is constructed differently than the consultation, the punishment clauses should be applied to prevent formal composition of ecological pathways. Fourth, We need to prepare measures to strengthen basic research for the installation of ecological pathways. Fifth, We need to strengthen the expost inspection function to compensate for the poorly created of ecological pathways. It is believed that the problems of ecological pathways created by consultation on environmental impact assessment could be corrected in the future. And it is deemed possible to systematically manage ecological pathways.

Fish communities in river networks provide significant ecosystem services that will likely decline under future land use and climate change. We developed a model that simulates the consequences to multiple populations of one or more fish species-a meta-community-from multiple stressors across a river network. The model is spatially-explicit and age-structured, with three components: habitat suitability; population dynamics, including species interactions; and movement across a spatial network. Although this model is simple, it can form the basis of fisheries assessments and may be incorporated into an integrated modeling system for watershed management and prediction.

Landscape ecology is an emerging interdisciplinary ecology field to understand the holistic human and natural systems on the basis of concept and database obtained from pure ecology. Landscape ecology is an integrated ecology widely available for environmental science such as nature conservation and sustainable land-use planning. It is also a practical study as an applied ecology to restore and to manage local environment. Landscape ecological study is realized by embodiment of human disturbance system which is rigorously extending on natural system. Considering Korean status without landscape ecological studies, we briefly reviewed establishing process, study goal and methodology of landscape ecology as well as the related several concepts through current landscape ecological studies in the world. We hope that this paper will be helpful to ecologists having interest in landscape ecology.

Peach (Prunus persica L.) is one of the major fruit crops in South Korea, along with apple, persimmon, and Asian pears. Peach anthracnose is a continuing threat to growers and is accountable for enormous economic loss. In July 2018, anthracnose of peach appeared at different peach orchards in Gyeongsangbuk-do region, Korea. The typical anthracnose symptoms (brown, circular, and necrotic lesions) were observed on the fruits. Anthracnose of peach was surveyed in different peach orchards of Gyeongsangbuk-do, and 20 fungal isolates from 19 diseased fruits were collected. Multigene phylogenetic analyses coupled with morphological characteristic analysis approaches were used for identifying the fungal species isolated from diseased fruits. This study confirmed three Colletotrichum species. Based on the results, Colletotrichum siamense are reported for the first time as causal agents of peach anthracnose alongside C. fructicola and C. fioriniae, which has been reported previously. Pathogenicity assays were performed for the three isolates representing all the species identified, and Koch's postulates on detached healthy peach fruits were verified. All the identified species were pathogenic on peach fruits as the typical anthracnose symptoms were reproduced. Significant variations in the virulence were observed among fungal species on peach fruit.

The purpose of this study was to investigate the effect of the experience-based ecology-environmental STEAM education on ecological sensitivity of elementary students. The research subjects were 62 third graders of S elementary school located in Incheon. They were divided into the experimental group of 33 students and the comparative group of 29 students. The experimental group was provided the educational program with the experience-based ecology-environmental STEAM education. The comparative group was provided the theoretical and ecological self activity program based on the textbook. The results of this study can be summarized as follows; First, the experience-based ecology-environmental STEAM education had a meaningful effect on improvement of ecological sensitivity. Second, we found that access to the ecological environment education is important in all subjects, not in education that is biased toward. Third, in ecological environment education, experience-oriented education methods are more meaningful than indirect experiences trapped in textbooks. Fourth, ecological environment education can contribute to the improvement of ecological sensitivity as well as the intellectual aspect of ecology and environmental science. In conclusion, it was found that the ecological environment program should be conducted with activities of experience.
