Available in PDF, EPUB and Kindle. Book excerpt: The beautifully written story of shells and their makers, and our relationships with them. Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet. But watch out. Some molluscs can kill you if you eat them. Some will kill you if you stand too close. That hasn't stopped people using shells in many ways over thousands of years. They became the first jewelry and oldest currencies; they've been used as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. Spirals in Time is an exuberant aquatic romp, revealing amazing tales of these undersea marvels. Helen Scales leads us on a journey into their realm, as she goes in search of everything from snails that 'fly' underwater on tiny wings to octopuses accused of stealing shells and giant mussels with golden beards that were supposedly the source of Jason's golden fleece, and learns how shells have been exchanged for human lives, tapped for mind-bending drugs and inspired advances in medical technology. Weaving through these stories are the remarkable animals that build them, creatures with fascinating tales to tell, a myriad of spiralling shells following just a few simple rules of mathematics and evolution. Shells are also bellwethers of our impact on the natural world. Some species have been overfished, others poisoned by polluted seas; perhaps most worryingly of all, molluscs are expected to fall victim to ocean acidification, a side-effect of climate change that may soon cause shells to simply melt away. But rather than dwelling on what we risk losing, Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.

Download or read book The Secret Life of Sharks written by A. Peter Klimley and published by Simon and Schuster. This book was released on 2008-06-17 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biologist Pete Klimley swims with the sharks. He was one of the first scientists to free-dive among sharks, and he has spent nearly thirty years studying shark behavior, sometimes swimming in schools of several hundred sharks. From his firsthand observations he has learned that sharks are not the vicious man-eaters that we imagine, but fascinating animals with complex behaviors. Most people who think of sharks at all think immediately of great white sharks. But there are more than four hundred species of shark. Dr. Klimley has studied several species, most notably the great white and the hammerhead. (He describes the great white as the athlete among sharks, and the hammerhead as the Ph.D. of the shark world.) In The Secret Life of Sharks Dr. Klimley reveals the significant discoveries he made about hammerhead navigation and great white eating habits. By studying hammerheads gathered around underwater seamounts, Dr. Klimley learned that hammerheads rely on sophisticated tracking of ocean-floor magnetism to navigate. His long-term study of great white sharks off the California coast demonstrated that these huge sharks prefer to eat seals and sea lions because of the energy contained in their fatty bodies. They are selective eaters, not the man-eaters we expect, and they sometimes go weeks between meals. But Dr. Klimley did observe a ritualized behavior that great whites practice in order to avoid deadly disputes over prey that one shark has captured and another wants. Although we have learned a great deal about shark behavior, says Dr. Klimley, there is much that we do not know. Unfortunately we are destroying these magnificent creatures of the deep through overfishing and degradation of the oceans. Already some populations of sharks have declined steeply. Vividly written by one of the foremost authorities on sharks, The Secret Life of Sharks is a fascinating account of some of the world's most magnificent animals.

Available in PDF, EPUB and Kindle. Book excerpt: Every spring, for thousands of years, the rivers that empty into the North Atlantic Ocean turn silver with migrating fish. Among the crowded schools once swam the King of Fish, the Atlantic salmon. From New York to Labrador, from Russia to Portugal, sea-bright salmon defied current, tide, and gravity, driven inland by instinct and memory to the very streams where they themselves emerged from gravel nests years before. The salmon pools and rivers of Maine achieved legendary status among anglers and since 1912, it was tradition that the first salmon caught in the Penobscot River each spring was presented as a token to the President of the United States. The last salmon presented was in 1992, to George W. Bush.That year, the Penobscot counted more than 70 percent of the salmon returns on the entire Eastern seaboard, yet that was only 2 percent of the river's historic populations. Due to commercial over harvesting, damming, and environmental degradation of the fish's home waters, Atlantic salmon populations had been decimated. The salmon is said to be as old as time and to know all the past and future. Twenty-two thousand years ago, someone carved a life-sized image of Atlantic salmon in the floor of a cave in southern France. Salmon were painted on rocks in Norway and Sweden. The salmon’s effortless leaping and ability to survive in both river and sea led the Celts to mythologize the salmon as holder of all mysterious knowledge, gained by consuming the nine hazelnuts of wisdom that fell into the Well of Segais. The President's Salmon presents a rich cultural and biological history of the Atlantic salmon and the salmon fishery, primarily revolving around the Penobscot River, the last bastion for the salmon in America and a key battleground site for the preservation of the species.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
