Background/Question/Methods

Sobaeksan National Park located in the center of the Baekdudaegan and the border of south and north in Korea. It is an important regions to aspects of geographical, biological and climatic from the past. The Baekdudaegan is a mountain range and watershed-crest-line which runs through most of the length of the Korean Peninsula, from Baekdu Mountain in the north to Jirisan in the south.To understand the timing of their interaction with other species by climate change, We are operate on the two super-sites programs in Sobaeksan National Park since 2014. The sites were assigned on the Namcheon valley in north slope and Keumsun valley in south slope. The climate of Mt. Sobaeksan is temperate to continental, with a dry, cold winter and hot, humid summer. The summer monsoon brings abundant moisture from the ocean and produces heavy rainfall. Mt. Sobaeksan has a long ridge line high above sea level that comprises plains, rocky areas, and long valleys that accommodate 1,067 plant species and 2,639 animal species

Results/Conclusions

Climate change is altering the phenology of many species and the timing of their interactions with other species, but the impacts of these phenological shifts on species interactions remain unclear.This study was to understand the interactions of bud burst in oaks, the emergence of their herbivores and. As a results, their were different responses to climate change for the relative timing of oak leaf unfolding, emergence of caterpillars and the breeding of insectivorous bird, resulting in the disruption of stage-structured interactions across three trophic levels. After oak leaf unfolding, Caterpillars generated after 3-4 days in 2014 year but take a 10-14 days in 2015.In general, timing of oak leaf unfolding is directly reacted with the temperature change but, caterpillars differed from the patterns on leaf unfolding, host plants and temperature. it is clear that we cannot expect to understand the consequences of phenological changes by investigating single species in isolation. Instead, understanding the full implications of climate change will require an integrated and mechanistic understanding of how climate change is affecting phenology, ontogeny and the timing of species interactions
