Summary
King George Island is one of the best places to study the effects of environmental changes of the ecosystem as it harbors diverse organisms and is strongly affected by global warming. Changes in temperature, water fall, wind speed, and wind direction from global warming may result in corresponding changes in microclimate such as light intensity by snow cover, air temperature, ground temperature, relative humidity, and soil water content. The Barton Peninsular of King George Island covers only a small area but the diversity in its geological features, such as in altitude and slope, result in various microclimates and simultaneously a diverse vegetation composition. Moreover, the Barton Peninsula, home to 2 flowering plants, 33 genera of mosses, and more than 35 genera of lichen, is an ecosystem with one of the most diverse vegetation in Antarctica. Understanding the physiological response of vegetation and adaptation mechanisms to the changing environment can provide insight when predicting vegetation change from global warming. In this project, we aimed to develop a biological response model by studying the distribution of vegetation according to the microclimate and their preferred niche, and the biological responses of the representative vegetation to the changing environmental factors.
