Co2 Acidification in Aquatic Ecosystems: An Integrative Approach to Risk Assessment

為了解決Aquatic ecosystem的問題,作者 這樣論述:

CO2 Acidification in Aquatic Ecosystems: An Integrative Approach to Risk Assessment focuses on the characterization of different aspects of ecosystem science to describe the situation of CO2 acidification in aquatic ecosystems. This extensive coverage looks at the effects of CO2 acidification thr

oughout all oceans and coastal areas. In addition, the book describes integrative approaches based on global case studies to determine the effects associated with this kind of acidification. It allows the reader to understand the different sources of CO2 in the aquatic ecosystems and the different a

pproaches and lines of evidence available to characterize the impact of this acidification.This book provides researchers, professors and post graduate students in oceanography and aquatic ecology with a new and complete tool set to address and understand the potential impacts of CO2 acidification i

台灣東北部海域廣東長吻鰩與尖棘甕鰩攝食生態研究

為了解決Aquatic ecosystem的問題,作者呂泰君 這樣論述:

鰩類族群豐度高且分佈範圍廣,其營養位階幾乎涵蓋海洋食物鏈的中上層,透過食性研究最能深入了解鰩類在海洋生態系中與其他物種的相互關系。本研究針對宜蘭大溪漁港拖網漁船於龜山島海域附近捕獲之廣東長吻鰩(Dipturus kwangtungensis)及尖棘甕鰩(Okamejei acutispina)進行胃內容物分析。本研究自2018年4月至2019年10月間共採集到廣東長吻鰩361尾(雄魚177尾,雌魚184尾)及尖棘甕鰩135尾(雄魚66尾,雌魚69尾)。兩種鰩之餌料生物累積曲線隨樣本數的增加呈現平緩的趨勢,代表本研究樣本數足以描述其攝食生態。研究結果顯示廣東長吻鰩主要餌料為甲殼類,餌料生物重要

性指數百分比(%RI)以無法鑑定的蝦類(unidentified shrimp)為最高(%RI = 45.34),其次為對蝦總科(Penaeoidea)(%RI = 16.56)以及細螯蝦屬(Leptochela spp.)(%RI = 13.60%)。餌料生物多樣性隨個體體長增加而上升,但空胃率僅於季節間有差異,雄、雌魚攝食組成高度重疊,體長組別間以小型個體與中型個體重疊度為最高,而小型個體與大型個體為最低,顯示廣東長吻鰩會隨成長改變攝食對象。尖棘甕鰩餌料重要性指數以無法鑑定的硬骨魚佔比例最高(%RI = 42.52),其次為無法鑑定的蝦(%RI = 25.06)及對蝦總科(%RI = 20

.77);餌料生物多樣性隨個體體長增加而上升,空胃率於性別間及季節間皆有差異。雄、雌魚攝食為高度重疊,體長組別間以中型個體與大型個體重疊度最高,顯示尖棘甕鰩亦會隨成長改變餌料生物。兩種鰩的攝食寬度經標準化後分別為0.03及0.05,皆為專一攝食物種;但由有效餌料生物數量(H')計算顯示其棲地餌料生物種類多且豐度極高,兩種鰩應為隨餌料生物豐度及優勢程度改變攝食特性之種類。

黑潮流域海底山之克赫波(Kelvin-Helmholtz billows)對海洋上層生態系統的影響

為了解決Aquatic ecosystem的問題,作者桂思緹 這樣論述:

克赫波可以驅動流經貧營養鹽黑潮在海底山周邊小尺度的海水混合。本研究目標主要探討不同之克赫波强度(或大小),包括「間歇小型」的小波狀況(small billow case; SBC)與「穩定大型」的大波狀况(large billow case; LBC)之克赫波對本海域硝酸鹽垂直通量的影響,並進一步瞭解其在海底山周遭生態系,不同環境條件下對超微型浮游生物及浮游動物組成之影響(第一章)。克赫波所造成之亂流動能耗散率 (turbulent kinetic energy dissipation rate; ε = O (10-7–10-6) W kg-1) 及渦流擴散率 (eddy diffusiv

ities; Kρ = O (10-4–10-3) m2 s-1) 明顯高於無克赫波(時),利用在此波內 Kρ 所估算之平均硝酸鹽通量最大值為 10.0 mmol m-2 day-1,此值遠高於黑潮流域之平均值(第二章);在較淺層形成的克赫波所攜入的硝酸鹽通量,將豐富次表層海域的無機營養鹽濃度;而靠近海底山頂較深的克赫波,則將會更有效率的從更深層水體中垂直向上傳輸豐富的硝酸鹽。另一方面,海底山周遭海域的超微浮游生物主要以異營性細菌為主(>50%; 第三章);然而,由於聚球藻生物量的增加,在海底山測站超微浮游生物的結果顯示出與近岸海域相似的生物碳量;此結果建議在貧營養鹽水體的黑潮流域,其海底山及

其周圍海域有類似沿岸海域海水的特性。另外,在冬季航次時黑潮有較強勁流速,其浮游動物生物量(SKC; 104.5 ml 100m-3)較夏季航次黑潮流速較弱時(WKC; 33.7 ml 100m-3)高出60%以上,但此差異可能主要是受到季節性的影響所致(第四章);另外,由浮游動物豐度的分布結果,顯示出海底山地形所形成的「阻塞效應」(blocking effect),會將它們聚集在海底山周遭與其側翼;然而,較強的黑潮海流時(例如SKC)可消除阻塞效應,並將浮游生物快速帶往下游。而在海底山周遭亦觀測到仔稚魚個體早期發育階段,顯見海底山有利於作為魚類產卵和繁殖的棲地。整體而言,本研究顯示黑潮流域海底

山之克赫波,對海底山生態系统之養分循環與垂直混和,對此海域的生產力與下游能量具有重要貢獻,並顯示海底山在貧養鹽黑潮海域扮演生命綠洲的角色。
