Lampreys: Biology, Conservation and Control

Book Description
This book, published in two volumes, provides the most comprehensive review of lamprey biology since Hardisty and Potter’s “The Biology of Lampreys” published more than 30 years ago. This second volume offers a synthesis of topics related to the lamprey gonad (e.g., lamprey sex ratios, sex determination and sex differentiation, sexual maturation, and sex steroids), the artifical propagation of lampreys, post-metamorphic feeding and the evolution of alternative feeding and migratory types, the history and status of sea lamprey control in the Laurentian Great Lakes and Lake Champlain, and an overview of contributions of lamprey developmental studies for understanding vertebrate evolution.

Book Description
New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.
Great Lakes Sea Lamprey

Book Description
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.
