Category: Juvenile Nonfiction
Have you seen a dodo bird recently? Do you have mastodons playing in your back yard? Not likely—these species are both extinct, which means the entire population has died out. More than 99 percent of all species, or about 5 billion, have gone extinct since life first formed on Earth 4.5 billion years ago. Some of those species went extinct at the same time in an event know as a mass extinction. What type of event could cause such a massive die off? This is a question that scientists have asked for decades as they explore the causes of extinction. In Extinction: What Happened to the Dinosaurs, Mastodons, and Dodo Birds? readers ages 9 to 12 learn about the scientific investigative work necessary to answer these questions and find the culprit behind mass extinctions. Follow the scientists as they look at all potential reasons for extinction, including asteroid impacts, massive volcanic eruptions, excessive gases in the atmosphere, climate change, and more. Where do scientists find clues to help them answer their questions? In rocks—scientists travel the globe to excavate the evidence. They look for fossils that might tell them what lived before an extinction and what lived after. They also examine the chemical elements in rocks at the boundaries between geologic eras, as well as the structure of rocks. As they follow the evidence, the pieces of the puzzle come together to form a clearer picture of events that happened millions of years ago, whether it’s an asteroid strike or a massive volcanic eruption. Extinction is not just a thing of the past. It is happening right now, at a higher rate than is typical. Because of this, there is debate about whether or not the presence of humans on Earth is having the same effect as an asteroid strike or a massive volcanic eruption. Are we currently experiencing the sixth mass extinction? And if so, what are the causes? Can we stop it? Extinction: What Happened to the Dinosaurs, Mastodons, and Dodo Birds? includes hands-on activities and critical thinking exercises to encourage readers to consider humans’ role in the current extinction, what we can learn from past extinction events, and how they can be part of efforts to prevent extinction. Hands-on activities, a fun narrative style, interesting facts, species spotlights, and links to primary sources combine to bring the subject of extinction to life in a fun and engaging way.

The term infonomics has been coined to convey the underlying value of information in terms of its production, market demand, and economic impact. All consumers have come to assume that the information they seek is easily accessible, and more importantly, free of charge. Infonomics and the Business of Free: Modern Value Creation for Information Services addresses the question of whether or not information has become a commodity and examines how infonomics and the “business of free” have changed the way companies must create and market their information to make it accessible and valuable for their customers. Information professionals who are responsible for creating valuable information and making services sustainable and accessible will greatly benefit from this book’s unique perspective and complete review of current research.
After a trip to the zoo, the Doctor and Martha go in search of a real life dodo, and are transported by the TARDIS to the mysterious Museum of the Last Ones. There, in the Earth section, they discover every extinct creature up to the present day - billions of them, from the tiniest insect to the biggest dinosaur, all still alive and in suspended animation. Preservation is the Museum's only job - collecting the last of every endangered species from all over the universe. And for millennia the Museum has been trying to trace one elusive specimen: the last of the Time Lords... Featuring the Tenth Doctor and Martha as played by David Tennant and Freema Agyeman in the acclaimed Doctor Who series from BBC Television.
If you could bring back just one animal from the past, what would you choose? It can be anyone or anything from history, from the King of the Dinosaurs, T. rex, to the King of Rock 'n' Roll, Elvis Presley, and beyond. De-extinction – the ability to bring extinct species back to life – is fast becoming reality. Around the globe, scientists are trying to de-extinct all manner of animals, including the woolly mammoth, the passenger pigeon and a bizarre species of flatulent frog. But de-extinction is more than just bringing back the dead. It's a science that can be used to save species, shape evolution and sculpt the future of life on our planet. In Bring Back the King, scientist and comedy writer Helen Pilcher goes on a quest to identify the perfect de-extinction candidate. Along the way, she asks if Elvis could be recreated from the DNA inside a pickled wart, investigates whether it's possible to raise a pet dodo, and considers the odds of a 21st century Neanderthal turning heads on public transport. Pondering the practicalities and the point of de-extinction, Bring Back the King is a witty and wry exploration of what is bound to become one of the hottest topics in conservation – if not in science as a whole – in the years to come. READ THIS BOOK – the King commands it.

The story of the dodo is a classic of evolution and extinction equal in fascination to that of the dinosaur or the saber-toothed tiger. Unlike these, however, the dodo was the first recorded example of an extinction that was, in all probability, entirely caused by humans. Humankind coexisted with the dodo between 1598 and 1681 and then the dodo was gone, hunted to extinction, unable to escape the new predators that arrived in ships on the isolated island later known as Mauritius. The giant pigeon, for this was what the dodo was, evolved from ancestors that had populated the island millions of years before in the Pleistocene period, when Mauritius was far adrift of where it lies today. The pigeons colonized an island paradise abundant with food, free of any terrestrial mammalian predators. Over millions of years they lost their instinct for danger. They also lost the ability to fly, and grew bulky with sturdy running legs. For the 17th-century sailors who arrived and settled on the island, they were easy to kill and as tasty as the turtles the sailors also caught and ate. The sailors introduced domestic animals and rat as well, competitors for the dodos' habitat. So much about the dodo is unknown and will never be known, and yet, the dodo engenders much speculation.The Dodo: Extinction in Paradiseexplores the science and the mythology, the history, archaeology, and legend, as well as the dodo's place in art and literature.

David Quammen's book, The Song of the Dodo, is a brilliant, stirring work, breathtaking in its scope, far-reaching in its message -- a crucial book in precarious times, which radically alters the way in which we understand the natural world and our place in that world. It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity. Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.
