The Life History and Ecology of River Herring in the Northeast
While on vacation in 1980, biologist Barbara Brennessel and her family came across an amazing sight: hundreds of small silver fish migrating from the Atlantic Ocean, across a channel connecting two ponds in the town of Wellfleet on Cape Cod. She later learned that these tiny river herring were important for the ecology and economy of the region and that volunteers were counting fewer and fewer fish migrating each year. The Alewives’ Tale describes the plight of alewives and blueback herring, two fish species that have similar life histories and are difficult to distinguish by sight. Collectively referred to as river herring, they have been economically important since colonial times as food, fertilizer, and bait. In recent years they have attracted much attention from environmentalists, especially as attempts are being made, on and beyond Cape Cod, to restore the rivers, streams, ponds, lakes, and estuaries that are crucial for their reproduction and survival. Brennessel provides an overview of the biology of the fish—from fertilized eggs to large schools of adults that migrate in the Atlantic Ocean—while describing the habitats at different stages of their life history. She explores the causes of the dramatic decline of river herring since the mid-twentieth century and the various efforts to restore these iconic fish to the historic populations that treated many onlookers to spectacular inland migrations each spring.
Science, Exploration, and the Theory of Continental Drift
Alfred Wegener aimed to create a revolution in science which would rank with those of Nicolaus Copernicus and Charles Darwin. After completing his doctoral studies in astronomy at the University of Berlin, Wegener found himself drawn not to observatory science but to rugged fieldwork, which allowed him to cross into a variety of disciplines. The author of the theory of continental drift—the direct ancestor of the modern theory of plate tectonics and one of the key scientific concepts of the past century—Wegener also made major contributions to geology, geophysics, astronomy, geodesy, atmospheric physics, meteorology, and glaciology. Remarkably, he completed this pathbreaking work while grappling variously with financial difficulty, war, economic depression, scientific isolation, illness, and injury. He ultimately died of overexertion on a journey to probe the Greenland icecap and calculate its rate of drift. This landmark biography—the only complete account of the scientist’s fascinating life and work—is the culmination of twenty years of intensive research. In Alfred Wegener, Mott T. Greene places Wegener’s upbringing and theoretical advances in earth science in the context of his brilliantly eclectic career, bringing Wegener to life by analyzing his published scientific work, delving into all of his surviving letters and journals, and tracing both his passionate commitment to science and his thrilling experiences as a polar explorer, a military officer during World War I, and a world-record–setting balloonist. In the course of writing this book, Greene traveled to every place that Alfred Wegener lived and worked—to Berlin, rural Brandenburg, Marburg, Hamburg, and Heidelberg in Germany; to Innsbruck and Graz in Austria; and onto the Greenland icecap. He also pored over archives in Copenhagen, Munich, Marburg, Graz, and Bremerhaven, where the majority of Wegener’s surviving papers are found. Written with great immediacy and descriptive power, Alfred Wegener is a powerful portrait of the scientist who pioneered the modern notion of unified Earth science. The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.
Plant and Animal Imports Into America
Aliens live among us. Thousands of species of nonnative flora and fauna have taken up residence within U.S. borders. Our lawns sprout African grasses, our roadsides flower with European weeds, and our homes harbor Asian, European, and African pests. Misguided enthusiasts deliberately introduced carp, kudzu, and starlings. And the American cowboy spread such alien life forms as cows, horses, tumbleweed, and anthrax, supplanting and supplementing the often unexpected ways "Native" Americans influenced the environment. Aliens in the Backyard recounts the origins and impacts of these and other nonindigenous species on our environment and pays overdue tribute to the resolve of nature to survive in the face of challenge and change. In considering the new home that imported species have made for themselves on the continent, John Leland departs from those environmentalists who universally decry the invasion of outsiders. Instead Leland finds that uncovering stories of alien arrivals and assimilation is a more intriguing—and ultimately more beneficial—endeavor. Mixing natural history with engaging anecdotes, Leland cuts through problematic myths coloring our grasp of the natural world and suggests that how these alien species have reshaped our landscape is now as much a part of our shared heritage as tales of our presidents and politics. Simultaneously he poses questions about which of our accepted icons are truly American (not apple pie or Kentucky bluegrass; not Idaho potatoes or Boston ivy). Leland's ode to survival reveals how plant and animal immigrants have made the country as much an environmental melting pot as its famed melding of human cultures, and he invites us to reconsider what it means to be American.
Naturalists, Collectors, and Biodiversity, 1850-1950
We humans share Earth with 1.4 million known species and millions more species that are still unrecorded. Yet we know surprisingly little about the practical work that produced the vast inventory we have to date of our fellow creatures. How were these multitudinous creatures collected, recorded, and named? When, and by whom?
Here a distinguished historian of science tells the story of the modern discovery of biodiversity. Robert Kohler argues that the work begun by Linnaeus culminated around 1900, when collecting and inventory were organized on a grand scale in natural history surveys. Supported by governments, museums, and universities, biologists launched hundreds of collecting expeditions to every corner of the world. Kohler conveys to readers the experience and feel of expeditionary travel: the customs and rhythms of collectors' daily work, and its special pleasures and pains.
A novel twist in this story is that survey collecting was rooted not just in science but also in new customs of outdoor recreation, such as hiking, camping, and sport hunting. These popular pursuits engendered a wide scientific interest in animals and plants and inspired wealthy nature-goers to pay for expeditions. The modern discovery of biodiversity became a reality when scientists' desire to know intersected with the culture of outdoor vacationing. General readers as well as scholars will find this book fascinating.
A Biosystematic Survey
The Aloineae, a tribe of several hundred species of succulent plants of the lily family, are ideal subjects for the study of karotypes and chromosome irregularities. This book brings together the major findings of a half-century of study of the Aloineae, with regard to polyploidy, aneuploidy, deletions, duplications, inversions, and translocations in the group.
The possible evolutionary effects of ecological relationships, natural hybridization, and morphological changes during growth are also assessed. Illustrations include maps, diagrams, photographs, photomicrographs, and electron micrographs.
The Outer Banks of North Carolina
The constant assault of natural forces make fragile barrier islands some of the most rapidly changing locations in the world, but human activities have had enormous impact on these islands as well. In Altered Environments, Jeffrey and Kathleen Pompe explore the complex interactions between nature and human habitation on the resilient Outer Banks of North Carolina. The Pompes employ modern and historical photographs and maps to illustrate the geographic and ecologic changes that have taken place on the Outer Banks, evaluating efforts to preserve these lands and also meet the evolving needs of a growing population. The Pompes examine the various forces that have created an environment so very different from the Outer Banks of only a few decades ago. The defining event in the reshaping of the islands for expanded development was the dune-construction project of the 1930s, when the Civilian Conservation Corps constructed a wall of self-sustaining dunes along 125 miles of Outer Banks shoreline in an effort to stave off beach erosion. This event created a historical demarcation in conservation efforts and heralded the beginning of a period of rapid economic development for the Outer Banks. The construction project reshaped the islands' geography to accomplish perceived economic advantages and prepared the Outer Banks for the last half of the twentieth century, when tourists increasingly visited this shore, bringing corresponding developments in their wake. The dune-restoration project is just one of the Pompes' examples of how human actions have altered the islands to meet the demands of a growing number of visitors and residents. While Altered Environments focuses on the Outer Banks, the narrative also considers social, environmental, and economic issues that are relevant to much of the seashore. Most coastal communities face similar problems, such as natural disasters and shoreline erosion, and in recent decades rapid population growth has exacerbated many conservation problems. Real-estate developments, the fisheries industry, tourism, climate change, and oil exploration all come under scrutiny in this investigation. Using the Outer Banks as a case study to frame a host of environmental challenges faced along the Atlantic seaboard today, the Pompes provide a valuable commentary on the historical context of these concerns and offer some insightful solutions that allow for sustainable communities.
Seven Scientists Search for the Origins of Goodness
In a world supposedly governed by ruthless survival of the fittest, why do we see acts of goodness in both animals and humans? This problem plagued Charles Darwin in the 1850s as he developed his theory of evolution through natural selection. Indeed, Darwin worried that the goodness he observed in nature could be the Achilles heel of his theory. Ever since then, scientists and other thinkers have engaged in a fierce debate about the origins of goodness that has dragged politics, philosophy, and religion into what remains a major question for evolutionary biology.
The Altruism Equation traces the history of this debate from Darwin to the present through an extraordinary cast of characters-from the Russian prince Petr Kropotkin, who wanted to base society on altruism, to the brilliant biologist George Price, who fell into poverty and succumbed to suicide as he obsessed over the problem. In a final surprising turn, William Hamilton, the scientist who came up with the equation that reduced altruism to the cold language of natural selection, desperately hoped that his theory did not apply to humans.
Hamilton's Rule, which states that relatives are worth helping in direct proportion to their blood relatedness, is as fundamental to evolutionary biology as Newton's laws of motion are to physics. But even today, decades after its formulation, Hamilton's Rule is still hotly debated among those who cannot accept that goodness can be explained by a simple mathematical formula. For the first time, Lee Alan Dugatkin brings to life the people, the issues, and the passions that have surrounded the altruism debate. Readers will be swept along by this fast-paced tale of history, biography, and scientific discovery.
Six Big Questions about Evolution
Despite the ongoing cultural controversy in America, evolution remains a cornerstone of science. In this book, Francisco J. Ayala—an evolutionary biologist, member of the National Academy of Sciences, and winner of the National Medal of Science and the Templeton Prize—cuts to the chase in a daring attempt to address, in nontechnical language, six perennial questions about evolution: • Am I a Monkey? • Why Is Evolution a Theory? • What Is DNA? • Do All Scientists Accept Evolution? • How Did Life Begin? • Can One Believe in Evolution and God? This to-the-point book answers each of these questions with force. Ayala's occasionally biting essays refuse to lend credence to disingenuous ideas and arguments. He lays out the basic science that underlies evolutionary theory, explains how the process works, and soundly makes the case for why evolution is not a threat to religion. Brief, incisive, topical, authoritative, Am I a Monkey? will take you a day to read and a lifetime to ponder.
