In order to investigate effects of elevated CO2 concentration and temperature on theecological niche of Quercus serrata in Korea. We divided experimental condition in the greenhousethat are control (ambient condition) and treatment with elevated CO2 (approximately 1.6 abovethan control) and increased air temperature (approximately 2.2°C above than control). We measuredtwenty kind characters of seedlings and calculated the ecological niche breadth. As a result,the ecological niche breadth, treatment was widened in the light gradient than the control, wasnarrowed in the moisture and nutrient gradient. This is may be predicted when the global warmingprogress, Q. serrata is increases resistance to light environment, and decrease resistance to moistureand nutrient environment. According to the principal component analysis (PCA), control and treatmentwere arranged based on factor 1 and 2 in each environment gradients. Ecological responseis involved variety characters. Among them, indicating that Characters of production is involvedin many a parts.
