The Last Winter: The Scientists, Adventurers, Journeymen, and Mavericks Trying to Save the World

為了解決Sea water的問題，作者Fox, Porter 這樣論述：

One man’s ＂curiously thrilling joyride＂ of travelogue, history, and climatology, across a planet on the brink of cataclysmic transformation (Donovan Hohn).As the planet warms, winter is shrinking. In the last fifty years, the Northern Hemisphere lost a million square miles of spring snowpack and

in the US alone, snow cover has been reduced by 15-30%. On average, winter has shrunk by a month in most northern latitudes. In this deeply researched, beautifully written, and adventure-filled book, journalist Porter Fox travels along the edge of the Northern Hemisphere’s snow line to track the sco

pe of this drastic change, and how it will literally change everything--from rapid sea level rise, to fresh water scarcity for two billion people, to massive greenhouse gas emissions from thawing permafrost, and a half dozen climate tipping points that could very well spell the end of our world. Thi

s original research is animated by four harrowing and illuminating journeys--each grounded by interviews with idiosyncratic, charismatic experts in their respective fields and Fox’s own narrative of growing up on a remote island in Northern Maine. Timely, atmospheric, and expertly investigated, The

Last Winter will showcase a shocking and unexpected casualty of climate change--that may well set off its own unstoppable warming cycle.

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Sea water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。

Clive Cussler’s Untitled Isaac Bell 13

為了解決Sea water的問題，作者Du Brul, Jack 這樣論述：

Detective Isaac Bell finds himself in hot water in the latest adventure from the #1 New York Times-bestselling Clive Cussler series. Clive Cussler was the author of more than eighty books in five bestselling series, including Dirk Pitt(R), NUMA(R) Files, Oregon(R) Files, Isaac Bell(R), and Sam and

Remi Fargo(R). His life nearly paralleled that of his hero Dirk Pitt. Whether searching for lost aircraft or leading expeditions to find famous shipwrecks, he and his NUMA crew of volunteers discovered and surveyed more than seventy-five lost ships of historic significance, including the long-lost

Civil War submarine Hunley, which was raised in 2000 with much publicity. Like Pitt, Cussler collected classic automobiles. His collection featured more than one hundred examples of custom coachwork. Cussler passed away in February 2020.Jack Du Brul is the author of the Philip Mercer series, most re

cently The Lightning Stones, and is the coauthor with Cussler of the Oregon Files novels Dark Watch, Skeleton Coast, Plague Ship, Corsair, The Silent Sea, and The Jungle, and the Isaac Bell novels The Saboteurs and The Titanic Secret. He lives in Virginia.

海洋酸化對點帶石斑仔稚魚鈣離子運輸以及骨骼鈣化作用的影響

為了解決Sea water的問題，作者黃辰宏 這樣論述：

根據政府間氣候變化專門委員會（IPCC）的預測，在本世紀末，二氧化碳濃度將提升至500~900 µatm，海水的酸鹼值則下降至7.9~7.7。海洋酸化會造成海水中碳酸鈣（CaCO3）飽和濃度升高，不利碳酸鈣在海水當中產生固態沉澱，並影響貝類以及珊瑚外骨骼的形成。此外，水體酸化可能會影響硬骨魚類的離子調節與發育生長，但並不清楚水體酸化是如何影響海洋硬骨魚類鈣離子的調節恆定性。本實驗比較飼養於正常的海水（pH 8.1）及不同酸化程度的海水（pH 7.8 與 pH 7.4）中40日齡點帶石斑仔稚魚，鈣離子運輸蛋白以及骨骼鈣質代謝相關基因在發育過程中的表現量變化。整體而言，實驗發現在酸化的環境之下仔

稚魚的成長與骨骼鈣離子累積並不會受到影響。然而，根據仔稚魚的離子調節、骨骼形成與鈣離子累積等數據的主成分分析卻顯示，水體酸化會影響整體的離子調節能力發展，以及可能輕微地影響對骨骼鈣離子沉積與再吸收。但是，若是以單一因子或以線性回歸進行分析與比較，則難以界定酸化對任何一組離子調控相關基因，例如細胞基底膜的鈣離子幫浦（pmca）、上皮鈣離子通道（ecac）以及運輸能量來源的鈉鉀離子幫浦基因的直接影響。此外，與骨骼鈣質沉積相關的成骨細胞（bglap）及破骨細胞（ctsk and trap）在海水酸化得情況下也並無獨立的顯著差異。實驗雖然表明在高二氧化碳的水體中，pH下降可能造成仔稚魚離子調節、骨骼形

成與鈣離子累積等因子的相互作用，而導致整體的生理差異。本研究亦顯示，點帶石斑魚仔稚魚的生長對高度酸化條件並不敏感，但此研究不能排除未來海洋酸化對沿海海水中的水產養殖業和野生種群影響的可能性。以目前而言，在海洋酸化的情況之下，硬骨魚的離子調節與鈣離子平衡的調節機制尚不明朗，須待更多研究證明。
