This year, we focus on birds, amphibians, freshwater fish and tree lines in alpine ecosystems to evaluate the climate change impact on terrestrial ecosystem in Taiwan. Our emphasis will be on the effect of climate changes on species level (endemic species, and rare species), and ecosystem level (hotspots, preserves, and alpine ecosystems). A suggestion of adaptation strategy based our findings will be proposed. Our tasks will include (1) reevaluation on the relationships of terrestrial biodiversity and environmental factors, and their changes under climate changes, (2) classifying the differences between men-made influences and climatic impacts, (3) a sensitivity analysis to evaluate the model stability, (4) risk assessment of biodiversity under climate change trend, and (5) recommendation of adaptation strategy. Our results shall provide basic information on how the biodiversity (structure, migration, displacement) in Taiwan will be affected in the future. An adaptation strategy that covers topics related to national land planning and zoning will be proposed. We hope these finding can be used as the foundation for biodiversity conservation and provide a direction for future climate change research in Taiwan.氣候變遷陸域生態國土規劃氣候影響climatic changeterrestrial biodiversitynational land planningclimatic impacts氣候變遷對我國之衝擊影響與調適策略研究-子計畫二:氣候變遷對陸域生物多樣性之衝擊評估及因應策略研究
