The Book of Eels by Patrik Svensson Pdf

A Finalist for the Los Angeles Times Book Prize National Bestseller Winner of the National Outdoor Book Award Longlisted for the Andrew Carnegie Medal for Excellence in Nonfiction A New York Times Notable Book One of TIME’s 100 Must Read Books of the Year One of The Washington Post’s 50 Notable Nonfiction Books of the Year One of Smithsonian Magazine’s 10 Best Science Books of the Year One of Publishers Weekly’s Best Nonfiction Books of the Year A New York Times Editor’s Choice Part H Is for Hawk, part The Soul of an Octopus, The Book of Eels is both a meditation on the world’s most elusive fish—the eel—and a reflection on the human condition Remarkably little is known about the European eel, Anguilla anguilla. So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery. Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson crafts a mesmerizing portrait of an unusual, utterly misunderstood, and completely captivating animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea. Blending memoir and nature writing at its best, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death. The result is a gripping and slippery narrative that will surprise and enchant.

Eels and Humans by Katsumi Tsukamoto,Mari Kuroki Pdf

This book explains much of what is known currently about freshwater eels, focusing on social and cultural aspects as well as science. A wealth of eel-related material is presented by scientists from around the world, including information on eel fishing, resources, distribution, aquaculture, economics, cuisine, environment and ecosystems, idioms, arts and crafts, tradition, legends, mythology, archaeology and even memorial services. Eels are important as food for humankind and are an interesting model for scientists studying animal migration and reproductive ecology. Their snake-like morphology differentiates them from most other fish, and their unpredictable behaviour that allows them to move over wet land and climb rocks adjacent to waterfalls attracts attention and evokes curiosity. Eels are therefore considered to be enigmatic creatures or metaphysical entities beyond human intelligence; indeed, they have been deified in parts of the world. In recent decades, however, with global populations of eels in sharp decline, some species face a real threat of extinction, and effective conservation strategies and measures are needed. Comparisons across these issues between various countries provide an image of a long-lasting relationship between eels and humankind, and encourage comprehensive and detailed understanding of eels from the perspectives of social, cultural and natural sciences. By promoting understanding of the close relationship between eels and humans, the broader public is engaged and public awareness of eel importance raised, helping to conserve these unique but endangered fish.

The Eel by F. Tesch Pdf

by Dr P .H. Greenwood British Museum (Natural History), London Dr Tesch's wide ranging account of anguillid eels impinges on the interests of many biologists; it is not simply a specialized tome narrowly aimed at ichthyologists and fishery scientists, rather it provides a source of primary reference and a comprehensive sununary of informa tion that is not likely to be superseded for a long time. It is significant that the bibliography includes references to learned journals concerned with physiology, pharmacology, taxonomy, genetics, zoology, endo crinology, botany, ecology and environmental interactions. Such is the breadth of interest in the Anguillidae. Few fish species have been subjected to as detailed review as Dr Tesch gives for the (wo Atlantic species of Anguilla. An equally comprehensive resume of research into the fourteen, rather less well-studied Indo Pacific species gives balance and reciprocal illumination to several biological problems posed by these similar but quite distinctive species.

Consider the Eel by Richard Schweid Pdf

Journalist Richard Schweid first learned the strange facts of the freshwater eel's life from a fisherman in a small Spanish town just south of Valencia. "The eeler who explained the animal's life cycle to me did so as he served up an eel he had just taken from a trap, killed, cleaned, and cooked in olive oil in an earthenware dish," writes Schweid. "I ate it with a chunk of fresh, crusty bread. It was delicious. I was immediately fascinated." As this engaging culinary and natural history reveals, the humble eel is indeed an amazing creature. Every European and American eel begins its life in the Sargasso Sea--a vast, weedy stretch of deep Atlantic waters between Bermuda and the Azores. Larval eels drift for up to three years until they reach the rivers of North America or Europe, where they mature and live as long as two decades before returning to the Sargasso to mate and die. Eels have never been bred successfully in captivity. Consulting fisherfolk, cooks, and scientists, Schweid takes the reader on a global tour to reveal the economic and gastronomic importance of eel in places such as eastern North Carolina, Spain, Northern Ireland, England, and Japan. (While this rich yet mild-tasting fish has virtually disappeared from U.S. tables, over $2 billion worth of eel is still eagerly consumed in Europe and Asia each year.) The book also includes recipes, both historic and contemporary, for preparing eel.

Spawning Migration of the European Eel by Guido van den Thillart,Sylvie Dufour,J. Cliff Rankin Pdf

Freshwater eels are almost infinitely improbable creatures. They spawn and die in the middle of the ocean, often associated with undersea mountains. Their tra- parent, leaf-like larvae move with ocean currents for months or years until they approach the mouths of freshwater rivers. Then they undergo a dramatic transf- mation in morphology, physiology and behavior. They move from their planktonic oceanic environment, migrate upstream and live for several years as apex fre- water predators. Then, almost impossibly, as they become sexually mature, they reverse their migration downstream to the ocean and back to spawning grounds to complete their life cycle. The dramatic changes in their life cycles are incredible. The efforts to unravel the details of their life history have been truly daunting. Much of the past research was the work of dedicated individuals who devoted their lifetime research to these fishes. Freshwater eels merit a separate chapter in almost any textbook dealing with ichthyology, marine biology or animal migration. We know a great deal about some aspects of the biology of freshwater eels. However, our understanding of their bi- ogy still resembles a work of art as much as a work of science. To some it appears like the sweeping brush strokes of a Japanese Zen landscape, to others it resembles the work of a French impressionist, and to still others it appears as magic realism.

Science Makes the World Go Round by Michael Böcher,Max Krott Pdf

Researchers in the environmental sciences are often frustrated because actors involved with practice do not follow their advice. This is the starting point of this book, which describes a new model for scientific knowledge transfer called RIU, for Research, Integration and Utilization. This model sees the factors needed for knowledge transfer as being state-of-the-art research and the effective, practical utilization to which it leads, and it highlights the importance of “integration”, which in this context means the active bi‐directional selection of those research results that are relevant for practice. In addition, the model underscores the importance of special allies who are powerful actors that support the application of scientific research results in society. An important product of this approach is a checklist of factors for successful knowledge transfer that will be useful for scientists. By using this checklist, research projects and research programs can be optimised with regard to their potential for reaching successful knowledge transfer effects.

Rewilding North America by Dave Foreman Pdf

In Rewilding North America, Dave Foreman takes on arguably the biggest ecological threat of our time: the global extinction crisis. He not only explains the problem in clear and powerful terms, but also offers a bold, hopeful, scientifically credible, and practically achievable solution. Foreman begins by setting out the specific evidence that a mass extinction is happening and analyzes how humans are causing it. Adapting Aldo Leopold's idea of ecological wounds, he details human impacts on species survival in seven categories, including direct killing, habitat loss and fragmentation, exotic species, and climate change. Foreman describes recent discoveries in conservation biology that call for wildlands networks instead of isolated protected areas, and, reviewing the history of protected areas, shows how wildlands networks are a logical next step for the conservation movement. The final section describes specific approaches for designing such networks (based on the work of the Wildlands Project, an organization Foreman helped to found) and offers concrete and workable reforms for establishing them. The author closes with an inspiring and empowering call to action for scientists and activists alike. Rewilding North America offers both a vision and a strategy for reconnecting, restoring, and rewilding the North American continent, and is an essential guidebook for anyone concerned with the future of life on earth.

Electron Energy-Loss Spectroscopy in the Electron Microscope by R.F. Egerton Pdf

to the Second Edition Since the first (1986) edition of this book, the numbers of installations, researchers, and research publications devoted to electron energy-loss spec troscopy (EELS) in the electron microscope have continued to expand. There has been a trend towards intermediate accelerating voltages and field-emission sources, both favorable to energy-loss spectroscopy, and sev eral types of energy-filtering microscope are now available commercially. Data-acquisition hardware and software, based on personal computers, have become more convenient and user-friendly. Among university re searchers, much thought has been given to the interpretation and utilization of near-edge fine structure. Most importantly, there have been many practi cal applications of EELS. This may reflect an increased awareness of the potentialities of the technique, but in many cases it is the result of skill and persistence on the part of the experimenters, often graduate students. To take account of these developments, the book has been extensively revised (over a period of two years) and more than a third of it rewritten. I have made various minor changes to the figures and added about 80 new ones. Except for a few small changes, the notation is the same as in the first edition, with all equations in SI units.
