"本研究計畫乃是台法三年期雙邊合作計畫，本計畫之目標嘗試瞭解橈足類在動態水體中扮演獵食者或獵物時在生態系中之角色，獵食者與獵物之互動包括游泳、搜尋、遭遇、攻擊、獵獲與消化等行為皆是本研究的目標，同時瞭解獵食者與獵物互動過程中小尺度與大尺度之機制變化模式，本研究之目標物種乃法國河口區最優勢且廣泛分佈的橈足類Eurytemora affinis （溫帶種）以及台灣河口區及各養殖池最優勢的橈足類 Pseudodiatomus annadalei（亞熱帶及熱帶種）作為實驗生物，本研究將探討此兩種生物在生態系中的知覺感官生物學與行為反應，尤其是他們扮演獵食者時或成為獵物時之角色；研究過程中環境參數將成為研究的中心議題，尤其是溫度參數（例如全球暖化）及鹽度參數（例如河口環境）對該兩關鍵物種所產生的行為變化，特別是游泳軌跡之變化將考慮二度空間與三度空間的變化，橈足類在動態水體扮演獵食者時或扮演獵物時其攝食與避敵機制之模式為何？將嘗試找到解答。本研究將有四位法國籍台法雙學位博士生參與此研究計畫，此外輔以博士後之協助，此跨國計畫將嘗試瞭解歐洲河口區最優勢且廣泛分佈的橈足類Eurytemora affinis 以及亞洲河口區及養殖池最優勢的橈足類 Pseudodiatomus annadalei在面臨全球暖化以及鹽度大幅度波動時，他們在獵食者與獵物互動過程中之行為模式，這些資料將使我們瞭解全球氣候變遷對兩個截然不同生態系之橈足類在獵食者與獵物動態互動變化中之角色與行為模式以及可能形成的影響。本跨國研究之目標冀望達成此跨國團隊在這兩關鍵物種上能深入的瞭解並做出具體貢獻且將研究成果陸續發表在許多優良的SCI期刊中。" "This is a three-year research project for bilateral collaboration between Taiwan and France. This research project is aimed to understand the role of copepod acting as a predator and as a prey under hydrodynamic conditions. The behavior of predator and prey and their interactions including swimming and search, encounter, attack, capture and ingestion will be investigated in both small- and large-scale studies. Both Eurytemora affinis from France and Pseudodiatomus annadalei from Taiwan, which are the dominat and widely distributed copepod species, will be the target species in this study. The sensory biology and the behavioral responses of these two species when acting both as a prey and as a predator will be investigated under several environmental parameters such as temperatures (e.g. global warming) and salinity fluctuation (e.g. estuary). Furthermore, their swimming trajectories will be studied in 2-D and 3-D. The feeding and escaping mechanisms, behavior responses during predator, and prey interactions under hydrodynamic conditions will be modeled. Four co-tutorial French Ph. D. students and one post-doctoral researcher will take part in this project. Results of this research project will equip us with a better understanding of the behavior of predator and prey and their interactions in the European and Asian dominant estuary copepod species when encountering global warming as well as salinity fluctuation environment such as estuary. Furthermore, it is expected that, many SCI papers will be published during the three years’ research period from this bilateral collaborative project."
