延續過去數年持續投入的研究工作，本團隊於 2018 年間以龜山島熱泉水域的研究成果一共發表了 9 篇科學性的學術報告。其中包含了熱泉環境、熱泉沉積物的化學組成、熱泉優勢的螃蟹生物學研究、熱泉之生物多樣性與熱泉微生物應用等多領域文章。接續前一年執行的研究工作，本計劃書之進行研究時間擬從2019年8月到2021年 7月期間，同時進行野外採樣與現場研究、實驗室研究與分析。研究主要探討高溫與低酸鹼度海水對於：(一) 龜山島淺海熱泉區烏龜怪方蟹之生理適應機制。研究重點在於探索高溫與低酸鹼度熱泉水如何影響烏龜怪方蟹的生理生態適應，以測線研究與異地移植實驗進行體內酵素的差異性比較；並利用熱泉水環境探索烏龜怪方蟹的嗅覺與視覺以及其它感官系統對於覓食、群聚等行為的影響。(二) 熱泉水對周圍浮游動物與橈足類的毒性反應與致死反應的研究。(三) 利用太空遙測的衛星影像資料，配合地理資訊系統的計算，探討龜山島熱泉活動的歷史演變以及對熱泉週邊生物的影響。(四) 持續分析長期龜山島浮游動物年間與季節間研究主題，追蹤分析周圍海域浮游動物的長期變動趨勢，建立長期生態資料庫，配合日後全球暖化與海洋酸化議題，瞭解該海域受到的衝擊與影響程度。本研究將增加我們對熱泉區主要熱泉生物尤其是烏龜怪方蟹與海域浮游動物之適應機制、生理反應與生態結構變遷的瞭解，研究結果將對瞭解熱泉區生物之生態與生理適應機制以及熱泉對週邊海洋生物歧異度的影響有更進一步的貢獻。最終目標為達成臺灣在熱泉生物的研究之領先地位。Continuing the research work that has been invested in the past few years, our team published a total of nine scientific reports in 2018 with the research results of hydrothermal vent in Guishan Island. It includes articles on hydrothermal vent environments, chemistry of thermal vent sediment, biology of thermal vent dominant crabs, biodiversity of thermal vent habitat and applications of thermal vent microbes. Follow the research work carried out in the previous year, the study aims to investigate the areas near shallow water hydrothermal vents (HV) at Kueishantao (KST), off the northeast coast of Taiwan (west Pacific) with field sampling, laboratory research, analysis and publication of the results obtained during the period from August 2019 to July 2021. The theme of the present study focuses on the effects of high temperature and low pH water at HVs on: (1) Physiological adaptation mechanism of shallow HV crabs (Xenograpsus testudinatus), particularly on how high-temperature and low pH affects physiological adaptations of crabs, comparing differences of enzyme activities in the body by transplanting crabs to areas outside the vents; and how olfaction and vision influences the foraging behavior of crabs at HVs; (2) Ecotoxicological tolerance of zooplankton and copepods, and HV water influence on mortality and physiological responses; (3) Using images from space and remote sensing satellite, combined with data from geographic information system programs, and tracking the historical evolution of the HVs at KST; (4) a continuation of the past study of KI zooplankton research issues, collecting zooplankton samples in the surrounding of KST waters, and establishing a longterm ecological database. This is to trace the impact and connection of global issues of global warming and ocean acidification at different regions of KST for a better understanding of the future ocean and global change biology. The present study will provide a better understanding of the adaptation mechanisms, physiological responses, and ecological structural changes of crabs (X. testudinatus) and zooplankton in the HV area of KST and its surroundings. The research results contribute to the knowledge and understanding of ecology, behavior, adaptation, physiology, and hydrobiology of the biota at the shallow HVs of KST. Particularly, the issue of impact of hydrothermal vent plumes on the biodiversity. We try to promote the shallow water hydrothermal vent research in Taiwan as one of the leading countries of the world.
