Lake Invaders: Invasive Species and the Battle for the Future of the Great Lakes

為了解決Quagga Zebra的問題,作者Rapai, William/ Design, T. G. (CRT) 這樣論述:

There are more than 180 exotic species in the Great Lakes. Some, such as green algae, the Asian tapeworm, and the suckermouth minnow, have had little or no impact so far. But a handful of others-sea lamprey, alewife, round goby, quagga mussel, zebra mussel, Eurasian watermilfoil, spiny water flea, a

nd rusty crayfish-have conducted an all-out assault on the Great Lakes and are winning the battle. In Lake Invaders: Invasive Species and the Battle for the Future of the Great Lakes, William Rapai focuses on the impact of these invasives. Chapters delve into the ecological and economic damage that

has occurred and is still occurring and explore educational efforts and policies designed to prevent new introductions into the Great Lakes.Rapai begins with a brief biological and geological history of the Great Lakes. He then examines the history of the Great Lakes from a human dimension, with the

construction of the Erie Canal and Welland Canal, opening the doors to an ecosystem that had previously been isolated. The seven chapters that follow each feature a different invasive species, with information about its arrival and impact, including a larger story of ballast water, control efforts,

and a forward-thinking shift to prevention. Rapai includes the perspectives of the many scientists, activists, politicians, commercial fishermen, educators, and boaters he interviewed in the course of his research. The final chapter focuses on the stories of the largely unnoticed and unrecognized a

dvocates who have committed themselves to slowing, stopping, and reversing the invasion and keeping the lakes resilient enough to absorb the inevitable attacks to come.Rapai makes a strong case for what is at stake with the growing number of invasive species in the lakes. He examines new policies an

d the tradeoffs that must be weighed, and ends with an inspired call for action. Although this volume tackles complex ecological, economical, and political issues, it does so in a balanced, lively, and very accessible way. Those interested in the history and future of the Great Lakes region, invasiv

e species, environmental policy making, and ecology will enjoy this informative and thought-provoking volume. William Rapai is an amateur naturalist and former newspaper journalist. He is the author of the 2013 Michigan Notable Book The Kirtland’s Warbler: The Story of a Bird’s Fight Against Extin

ction and the People Who Saved It.

藉由生態系結構及功能探討都市公園濕地之生態效益:以大安森林公園生態池為例

為了解決Quagga Zebra的問題,作者黃宥禎 這樣論述:

都市公園水池常用作補償因人類活動導致消失及劣化的天然濕地,但公園水池的生態價值往往被忽略而疏於管理,以致其經常面臨不同環境及生態的衝擊。本研究為解決公園水池優養化與藻華問題,於臺北市中心的大安森林公園之三座生態池作為研究樣點,於2018 – 2020年期間每月進行水質監測及大型底棲無脊椎動物調查,以探討都市公園水池的優養化程度及其對生物多樣性之影響;並探討優養化對都市公園水池生態效益之衝擊。另外,本研究應用臺灣原生圓蚌(Anodonta woodiana)於優養化及藻華問題最嚴重的生態池進行生物操控淨水試驗,以探討應用圓蚌淨化優養化及藻華之都市公園水池的效果與可行性。結果顯示三座生態池的水質

全年皆為優養化,另因大量水鳥棲息於一號池排放之糞便流入水體導致嚴重的藻華問題。本研究應用圓蚌作生物操控法淨化一號池水質,結果為圓蚌能顯著降低一號池水中葉綠素a濃度43.0 %,且圓蚌設置期間的存活率> 94 %,證實圓蚌能成功存活並淨化優養化及藻華之都市公園水池,建議未來應推動本研究所建立圓蚌生物操控模式為生態友善之水質改善方法。本研究針對三座生態池的生態系服務評估,結果顯示優養化及藻華問題改變一號池的生物群聚結構,導致該池除了主要提供營養循環及初級生產者服務外亦提供削減的水質淨化負面服務;二號池及三號池主要提供正面生物多樣性、水質淨化及文化服務,但外來種入侵問題導致該兩座生態池亦提供削減的生

物多樣性及水質淨化負面服務。本研究發現優養化及藻華問題造成一號池生物多樣性低並轉以雙翅目與寡毛亞綱為主要優勢生物類群,二號池及三號池生物多樣性比一號池高,卻有福壽螺及大理石紋螯蝦外來種入侵問題。本研究依據研究期間之水質特性及生物群聚結構變化,建立合適生態池水質及生物監測作定期評估都市公園水池的優養化狀況,而雙翅目水生昆蟲合適作為監測都市公園水池優養化及藻華程度的生物指標。

應用環境 DNA 技術輔助調查漁港漁獲組成

為了解決Quagga Zebra的問題,作者葉羽真 這樣論述:

近年來隨著保育意識逐漸抬頭,有愈來愈多受到生存危機的海洋生物被列入保育,其中較知名的包括海龜及鯊魚等。然而,少數漁民在不認識保育生物或無意識的混獲下,仍有可能危害到這些珍貴物種。因此,如何以最簡便且有效的方法偵測出保育物種是否在漁獲中, 以利於進行長期監測,是未來保育管理上的一個重要課題。環境DNA(environment DNA, eDNA)來自於棲地中的各種生物,是在環境中持續存在的遺傳物質。目前有許多研究已應用環境DNA於海洋生物的調查上,特別是棲地廣大、不易被觀察到的物種。通過PCR擴增和DNA定序技術,我們可以在不捕捉樣本的條件下,將特定物種鑑別出來。甚至在不具有特定目標時,也可以

透過通用引子對,以DNA條碼(DNA barcoding),結合次世代定序技術,實現多物種的環境DNA定性檢測(eDNA metabarcoding)。本研究使用最新的環境DNA檢測技術,並實地於南方澳及大溪漁港調查到軟骨魚綱共72個魚種,其中12種為瀕危物種, 未來進行長期調查,將有助於我們釐清漁港物種組成及漁業活動中是否具無意識混獲保育物種的情況。關鍵詞:漁業、保育、環境DNA、DNA條碼
