Download or read book Great Lakes Sea Lamprey written by Cory Brant and published by University of Michigan Press. This book was released on 2019-08-22 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stuff of nightmares in both their looks and the wounds inflicted on their victims, sea lampreys (Petromyzon marinus) are perhaps the deadliest invasive species to ever enter the Great Lakes. At the invasion’s apex in the mid-20th century, harvests of lake trout (Salvelinus namaycush), the lampreys’ preferred host fish in the Great Lakes, plummeted from peak annual catches of 15 million pounds to just a few hundred thousand pounds per year—a drop of 98% in only a few decades. Threatening the complete collapse of the fishery, the sea lamprey invasion triggered an environmental awakening in the region and prompted an international treaty that secured unprecedented cooperation across political boundaries to protect the Great Lakes. Fueled by a pioneering scientific spirit, the war on Great Lakes sea lampreys led to discoveries that are the backbone of the program that eventually brought the creature under control and still protects the largest freshwater ecosystem in the world to this day. Great Lakes Sea Lamprey draws on extensive interviews with individuals who experienced the invasion firsthand as well as a trove of unexplored archival materials to tell the incredible story of sea lamprey in the Great Lakes—what started the invasion, how it was halted, and what this history can teach us about the response to biological invaders in the present and future. Richly illustrated with color and black & white photographs, the book will interest readers concerned with the health of the Great Lakes, the history of the conservation movement, and the ongoing threat of invasive species.

Book excerpt: Siberia's Lake Baikal is one of nature's most magnificent creations, the largest and deepest body of fresh water in the world. And yet it is nearly unknown outside of Russia. In Sacred Sea--the first major journalistic examination of Baikal in English--veteran environmental writer Peter Thomson and his younger brother undertake a kind of pilgrimage, journeying 25,000 miles by land and sea to reach this extraordinary lake. At Baikal they find a place of sublime beauty, deep history, and immense natural power. But they also find ominous signs that this perfect eco-system--containing one-fifth of earth's fresh water and said to possess a mythical ability to cleanse itself--could yet succumb to the even more powerful forces of human hubris, carelessness, and ignorance. Ultimately, they help us see that despite its isolation, Baikal is connected to everything else on Earth, and that it will need the love and devotion of people around the world to protect it.

Download or read book Texas Aquatic Science written by Rudolph A. Rosen and published by Texas A&M University Press. This book was released on 2014-11-19 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.
