Nature's Giants - The Biology and Evolution of the World's Largest Lifeforms (Hardcover): Graeme D. Ruxton Nature's Giants - The Biology and Evolution of the World's Largest Lifeforms (Hardcover)

R683 R492 Discovery Miles 4 920 Save R191 (28%) Shipped within 7 - 12 working days

A beautifully illustrated exploration of the science behind the awe-inspiring giants of past and present

The colossal plants and animals of our world-dinosaurs, whales, and even trees-are a source of unending fascination, and their sheer scale can be truly impressive. Size is integral to the way that organisms experience the world: a puddle that a human being would step over without thinking is an entire world to thousands of microscopic rotifers. But why are creatures the size that they are? Why aren't bugs the size of elephants, or whales the size of goldfish?

In this lavishly illustrated new book, biologist Graeme Ruxton explains how and why nature's giants came to be so big-for example, how decreased oxygen levels limited the size of insects and how island isolation allowed small-bodied animals to evolve larger body sizes. Through a diverse array of examples, from huge butterflies to giant squid, Ruxton explores the physics, biology, and evolutionary drivers behind organism size, showing what it's like to live large.

As read by James Corden, Fearne Cotton, Jim Chapman and Dougie Poytner. 'We have a responsibility, every one of us' David Attenborough Around 12.7 million tonnes of plastic are entering the ocean every year, killing over 1 million seabirds and 100,000 marine mammals. By 2050 there could be more plastic in the ocean than fish by weight. Plastic pollution is the environmental scourge of our age, but how can YOU make a difference? This accessible guide, written by the campaigner at the forefront of the anti-plastic movement, will help you make the small changes that make a big difference, from buying a reusable coffee cup to running a clean-up at your local park or beach. Tips on giving up plastic include: * Washing your clothes within a wash bag to catch plastic microfibers (the cause of 30% of plastic pollution in the ocean) * Replacing your regular shampoo with bar shampoo * How to lobby your supermarket to remove unnecessary packaging * How to throw a plastic-free birthday party * How to convince others to join you in giving up plastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers. This is a call to arms - to join forces across the world and to end our dependence on plastic. #BreakFreeFromPlastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers.

The lives and activities of seabirds as you've never seen them before Seabirds evoke the spirit of the earth's wildest places. They spend large portions of their lives at sea, often far from land, and nest on beautiful and remote islands that humans rarely visit. Thanks to the development of increasingly sophisticated and miniaturized devices that can track their every movement and behavior, it is now possible to observe the mysterious lives of these remarkable creatures as never before. This beautifully illustrated book takes you on a breathtaking journey around the globe to reveal where these birds actually go when they roam the sea, the tactics they employ to traverse vast tracts of ocean, the strategies they use to evade threats, and more. Michael Brooke has visited every corner of the world in his lifelong pursuit of seabirds. Here, he draws on his own experiences and insights as well as the latest cutting-edge science to shed light on the elusive seafaring lives of albatrosses, frigatebirds, cormorants, and other ocean wanderers. Where do puffins go in the winter? How deep do penguins dive? From how far away can an albatross spot a fishing vessel worth following for its next meal? Brooke addresses these and other questions in this delightful book. Along the way, he reveals that seabirds are not the aimless wind-tossed creatures they may appear to be and explains the observational innovations that are driving this exciting area of research. Featuring illustrations by renowned artist Bruce Pearson and packed with intriguing facts, Far from Land provides an extraordinary up-close look at the activities of seabirds.

Bats are fascinating mammals about which we still have much to learn. As well as using ultrasonic echolocation calls for orientation and while foraging, they also have a complex array of vocalisations for communication. These are known as social calls and are an essential component of their colonial lifestyle. This book brings together the current state of knowledge of social calls relating to the bat species occurring within Britain and Ireland, with some additional examples from species represented elsewhere in Europe. It includes access to a downloadable library of calls to be used in conjunction with the book. Downloadable call library Social calls are complex and intriguing to listen to; they are after all produced with listeners in mind (other bats). To enjoy and fully appreciate social calls the reader must also have the opportunity to become a listener: each of the presented sonograms in the book is cross-referenced to downloadable `time expanded' .wav sound files which are contained within a much wider library of calls for you to explore. Included in Social Calls of the Bats of Britain and Ireland The authors start with an overview of the species of bats in Britain and Ireland (Chapter 1), and then introduce us to communication within the social world of bats (Chapter 2). Referencing the latest research, the authors explore how these calls can be classified according to their structure, and in many cases the context in which the calls are thought to be emitted (Chapter 3). Chapter 4 addresses aspects of survey methodology to be considered by those studying social calls. This leads on to the analysis of calls (Chapter 5), detailing the specific methods used and parameters commonly measured by researchers. The final, and main chapter (Chapter 6) introduces the 23 species covered in the book giving each a detailed profile including: habitat preferences, typical roosting locations, roost emergence times, mating strategies and maternity behaviour. Each species profile includes what is known about the social calls for that species and this text is supported by colour sonograms (created using Pettersson BatSound V4.1) of most of the calls discussed. Each sonogram is linked to a .wav sound file (Time Expansion x10) within the downloadable library. The sound files allow the reader to hear, as well as see, the calls produced using any bat sound analysis software that supports the .wav format. The authors conclude with a bibliography and an extensive list of references directly cross-referenced throughout the book.

The diamond-backed terrapin is not only a uniquely evolved and beautiful turtle, it also has a long history as a vital American food source. Once so numerous that people reportedly grew tired of eating them, diamond-backed terrapins are greatly reduced in numbers today and have become an icon of salt marsh conservation. Considerably diminished in some areas and struggling to survive, this distinctive brackish water turtle is the focus of intense conservation efforts. In Ecology and Conservation of the Diamond-backed Terrapin, leading terrapin researcher Willem M. Roosenburg and experienced science editor Victor S. Kennedy have brought together a group of expert scientists to summarize our current understanding of terrapin biology, physiology, behavior, and conservation efforts. Over the course of 19 comprehensive chapters, contributors * review the latest information on this charismatic species * provide a detailed summary of the terrapin's natural history * explain the threats to terrapin population stability throughout their range* examine ongoing conservation efforts to ensure the reptile's survival* present convincing arguments for the value of the diamond-backed terrapin as an estuarine indicator organism* use the terrapin as a model for studying the consequences of exploitation and environmental degradation on long-lived species This exceptional book provides pivotal information for estuarine and turtle biologists, terrapin enthusiasts, natural historians, educators, conservationists, resource managers, and students. Ecology and Conservation of the Diamond-backed Terrapin is the definitive volume on this important American reptile. Contributors: Benjamin K. Atkinson, Harold W. Avery, Patrick J. Baker, Ralph E.J.

The evolution of high-crowned teeth, hypsodonty, is a defining characteristic of many terrestrial herbivores. To date, the most prominent focus in the study of the teeth of grazing herbivores has been co-evolution with grasses and grasslands. This book develops the idea further and looks at the myriad ways that soil can enter the diet. Madden then expands this analysis to examine the earth surface processes that mobilize sediment in the environment. The text delivers a global perspective on tooth wear and soil erosion, with examples from the islands of New Zealand to the South American Andes, highlighting how similar geological processes worldwide result in convergent evolution. The final chapter includes a review of elodonty in the fossil record and its environmental consequences. Offering new insights into geomorphology and adaptive and evolutionary morphology, this text will be of value to any researcher interested in the evolution of tooth size and shape.

Most people think of pythons as giant snakes in distant tropical jungles, but Burmese pythons, which can reach lengths of over twenty feet and weigh over two hundred pounds, are now thriving in southern Florida. These natives of Asia are commonly kept as pets and presumably escaped or were released in the Everglades. Pythons are now common in this region; widespread throughout hundreds of square miles, they are breeding and appear to be expanding their range. Pythons are voracious predators that feed on a variety of native wildlife including wading birds, bobcats, white-tailed deer, and even alligators. Their presence has drawn dramatic media attention and stoked fears among the public that pythons may threaten not just native species but humans as well. Despite this widespread concern, information on pythons has been limited to a few scientific publications and news coverage that varies widely in fact and accuracy. With Invasive Pythons in the United States, Michael E. Dorcas and John D. Willson provide the most reliable, up-to-date, and scientifically grounded information on invasive pythons. Filled with over two hundred color photographs and fifteen figures and maps, the book will help general readers and the scientific community better understand these fascinating animals and their troubling presence in the United States. Features information on general python biology biology of Burmese pythons in their native range research on pythons in the United States history and status of introduced pythons in Florida risks pythons pose in Florida and elsewhere methods to control python populations other boas and pythons that may become or are already established in the United States
