An examination of the ecological damage that has been done by several invasive species in the Great Lakes. 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, and 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 advocates 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 and 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, invasive species, environmental policy making, and ecology will enjoy this informative and thought-provoking volume.

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.

From killer toads, feral felines, and brown tree snakes to multiple invaders in the Great Lakes and Lake Victoria, Alien Invaders explores the impact on our ecosystems of the wave after wave of invaders and why they have become a worldwide concern. Environmentalists Jane Drake and Ann Love take us on a journey from the days of sailing ships and shipboard rats to the fungus that sparked the Irish potato famine to the beautiful but deadly purple loosestrife strangling native wetlands, while presenting the concepts of biodiversity and endangered species. Learn where the invaders originate, how they travel, what they displace, why the invaded natural system is vulnerable, and what can be done. Discover if you are an invader or a saver and how you can help.

The Laurentian Great Lakes are the largest unfrozen reservoir of freshwater on earth, accounting for almost one-fifth of the worlds fresh surface water. They are vital to the economy of the Great Lakes region and to the quality of life of its residents, providing drinking water for more than 33 million people in Canada and the United States, supplying hydroelectric power, supporting industries, providing waterborne transportation, and offering a variety of recreational opportunities. Human activities have, however, imposed stresses on the Great Lakes basins ecological integrity, and one of these stresses the introduction of nonindigenous species of animals and plants is the focus of this report. The opening of the St. Lawrence Seaway in 1959 provided a route into the Great Lakes not only for international maritime trade but also for aquatic invasive species (AIS) carried in the ballast water needed by ships to operate safely. Ships ballast water is not the only vector by which AIS enter the Great Lakes, but it has accounted for 55 to 70 percent of reported AIS introductions since 1959, including that of the zebra mussel (Dreissena polymorpha).

The Great Lakes are the largest collection of fresh surface water on earth, and more than 40 million Americans and Canadians live in their basin. Will we divert water from the Great Lakes, causing them to end up like Central Asia's Aral Sea, which has lost 90 percent of its surface area and 75 percent of its volume since 1960? Or will we come to see that unregulated water withdrawals are ultimately catastrophic? Peter Annin writes a fast-paced account of the people and stories behind these upcoming battles. Destined to be the definitive story for the general public as well as policymakers, The Great Lakes Water Wars is a balanced, comprehensive look behind the scenes at the conflicts and compromises that are the past-and future-of this unique resource.

the Sea Lamprey have invades the Great Lakes where they have killed off native species and harmed the fishing industry. Find out hoe they arrived, the problems they cause and other places that are on the lookout for these animals.

Short-listed for the 2007 CBA Libris Awards for Book Design of the Year What do Superman, Prince Valiant, Cerebus the Aardvark, and Spawn have in common? Their creators Joe Shuster, Harold Foster, Dave Sim, and Todd McFarlane are Canadians. And while many of the cutting-edge talents of contemporary comix and graphic novels are also from Canada artists such as Chester Brown, Seth, Dave Cooper, and Julie Doucet far too few Canadians realize their country had a remarkable involvement with the "funnies" long before. Invaders from the North profiles past and present comic geniuses, sheds light on unjustly neglected chapters in Canadas pop history, and demonstrates how this nation has vaulted to the forefront of international comic art, successfully challenging the long-established boundaries between high and low culture. Generously illustrated with black-and-white and colour comic covers and panels, Invaders from the North serves up a cheeky, brash cavalcade of flamboyant and outrageous personalities and characters that graphically attest to Canadas verve and invention in the world of visual storytelling.

At a time when the world is seeing its species rapidly go extinct, the Kirtland's warbler is not just a survivor, it's a rock star. The Kirtland's warbler is the rarest warbler species in North America and will always be rare because of its persnickety nesting preferences. But when the total population fell below 400 birds in the 1970s and 1980s---driven largely by a loss of habitat and the introduction of a parasite---a small group of dedicated biologists, researchers, and volunteers vowed to save the Kirtland's warbler despite long odds. This is the story of the warbler's survival and gradual recovery, the people and policies that kept it from extinction, and the ongoing challenges that may again jeopardize the bird's future. In The Kirtland's Warbler, William Rapai explores the bird's fascinating natural history as well as the complex and evolving relationships between the warbler, its environment, its human protectors, and state and federal policies that today threaten to eradicate decades of work done on the species' behalf. Beginning with an account of the warbler's discovery in the mid-nineteenth century and ornithologists' desperate hunt for information on the elusive new species, the book goes on to examine the dramatic events that quickly led to the warbler's precarious status and its eventual emergence as a lightning rod for controversy. The Kirtland's warbler is often described as a "bird of fire" for its preference for nesting in areas cleared by wildfire. But it also warrants the name for the passion it ignites in humans. Both tragic and uplifting, the story of this intriguing bird is a stirring example of how strong leadership, vision, commitment, sustained effort, and cooperation can come together to protect our natural world.
