William Rapai - Böcker

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.

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, andboaters 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.
