1.極端生物的典範-探索淺海熱泉系統中海洋共生體的適應機制
熱泉系統支持著獨特的生態系統,其中包含了從微生物到脊椎動物豐富的生物多樣性。我們發現:在熱泉系統棲息的烏龜怪方蟹(Xenograpsus testudinatus)具有比其他物種更好的控制硫化物濃度能力,在其身上,更存在有特殊菌相,與烏龜怪方蟹形成特殊的細胞內共生關係。

2. 全球暖化進程下的「溫水煮魚」效應
自2010年以來,臺灣南部水產養殖區域冬季氣溫高於25°C的發生機率愈來愈頻繁,因此導致日間溫度變化幅度正逐漸下降。根據我們的系統性的代謝分析策略發現:全球暖化導致每年的溫度變化幅度縮小與趨於穩定,會產生如同「溫水煮青蛙」的效應,導致熱帶吳郭魚的能量保存降低。因此,魚類在數個世代缺乏低溫緊迫的經歷後,可能會降低這些亞熱帶/熱帶生物原有的耐寒性狀;一旦副北極效應造成的「霸王級寒流」,魚類就會因為代謝失衡而無法及時進行生理調整。

3. 海洋酸化進程中,海洋生物的跨世代反應
工業革命後,人類活動造成大氣中二氧化碳濃度逐漸上升導致海水的pH值下降,這個現象稱為「海洋酸化」。近年針對海洋生物反應的相關研究發現:海洋動物在跨世代環境適應過程中,生理與行為等表徵亦會產生表觀遺傳特性的修飾機制。藉由比較不同海洋生物的綜合性研究,我們得以瞭解未來海洋生物可能的分佈、反應、與後續的生態鏈連鎖效應。
