摘要：目前研究已知全球氣候變遷造成許多生物與環境狀態的改變，如物種遷移、物候期推移、生態系平衡改變與極端氣候的發生等，導致許多稀有、特有及脆弱的生物族群面臨棲地縮減與族群孤離的壓力。為了因應全球的趨勢及聯合國永續會所倡議的方針，同時考量台灣目前可探討氣候變遷相關資訊之現況條件，本計畫擬利用台灣已蒐集之長期植物標本與野外調查資料，檢視原生維管束植物的地理分布情形，選取中海拔的台灣水青岡及高海拔的台灣冷杉為代表物種，利用不同地區族群之遺傳多樣性分析，比較不同大小族群間的遺傳多樣性及遺傳結構差異，探討其與冰河期後歷經氣候暖化、族群遷徙、隔離與生育地片斷化的影響，進而討論氣候變遷與生物多樣性的互動關係。
Abstract: Global climate change has known to cause biological and environmental imbalances, such as species migration, phenological shift, changes in ecosystem equilibrium, and incidence of extreme weather. Such alterations can make many rare and vulnerable species facing severe pressure of population isolation and habitat reduction. In this project, we incorporate various sources of databases on plant species distribution, as well as genetic diversity in selected species, to evaluate impacts of climate change on biodiversity in Taiwan based on the guidelines provided by the United Nations Commission on Sustainable Development (UNCSD). We will examine the distribution patterns of vascular plants. We also selected Fagus hayatae and Abies kawakamii, representing mid and high altitude species, for comparison of genetic diversity between large and isolated (relic) populations. The results will be compared with predictions from global warming, population dynamics, and habitat fragmentation, and their influences on biodiversity.
