本研究之進行時間擬從 2013 年 8 月到 2016 年 7 月期間，經由野外採樣調查、分析與實驗室同時進行研究。本研究主題分成四大方向：(一) 龜山島淺海熱泉噴口之海洋物理傳輸過程對浮游動物所形成的影響以及浮游動物之生態毒理學的耐受性研究。(二) 熱泉區烏龜怪方蟹之形質研究，並探討離熱泉噴出口近 (3 米內)、中 (3-20 米)、遠 (20 米以外) 不同距離之族群分佈，進一步對其行為模式作深入之探討。在過去幾年的調查中，我們發現熱泉區鄰近海底存在著不少能忍受熱泉混合水的珊瑚 (管星珊瑚屬, Tubastraea genera) 與螺類。我們的計畫 (三) 將於後續的研究裡分析這些存活於熱泉影響範圍內之珊瑚，在研究室中利用掃描式電子顯微鏡 (SEM) 觀察珊瑚於不同 pH 值的海水中其骨骼構造之變化，探討熱泉對珊瑚的影響。(四) 對於熱泉區附近之螺類多樣性、分佈與豐度做初步調查，藉由 SEM 瞭解熱泉是否對螺類外殼形成產生影響。透過本研究系統化的探討，將增加我們對熱泉區生物相之組成、生理及生態結構的瞭解，研究結果將對海底熱泉湧出影響範圍之海域浮游動物、烏龜怪方蟹、珊瑚與螺類等生物在生態、生活史、行為、適應及個體生物學有更進一步的瞭解與貢獻。 In present study is aim to investigation the areas near shallow water hydrothermal vents at Turtle Island, off the northeast coast of Taiwan (west Pacific) in the period from August 2013 to July 2016. The experimental works of field sampling, analysis and laboratory research will hold at same time. The theme of present study is focus on four main issues: (A) The physical transport processes of the Turtle Island the shallow hydrothermal vents, the ecotoxicological tolerance of zooplankton, and hydrothermal vents influence on abundance, composition, distribution and variety of spatial and temporal variations of zooplankton. (B) The width/length-weight relationships and distribution of hydrothermal vent crabs (Xenograpsus testudinatus), and investigation the distribution of crab population at different distances of nearly zone (3 meters), medium zone (3-20 meters), far zone (20 meters away) at the hydrothermal vent area. Further the behavior patterns of crabs from hydrothermal vent. From the survey of past few years, we found a lot peculiar corals (Tubastraea genera) and snails could tolerate mixed vent water live in areas adjacent to hydrothermal vent. The issue (C) is aim to study these peculiar corals which survival around hydrothermal vent. In the laboratory, use a scanning electron microscope (SEM) to identify the changes of coral skeleton from different pH seawater. (D) Investigate the diversity, the distribution and abundance of snails and study the impact of the hydrothermal vent on snails shell by SEM. Through a systematic investigate of present study, will increase understanding the biota composition, biological, physiological and ecological structure in hydrothermal vent area. The research results will contribute the knowledge and understanding in ecology, life history, behavior, adaptation, physiology and idiobiology of the zooplankton, vent crabs (Xenograpsus testudinatus), corals and snails in hydrothermal vent area.
