Available in PDF, EPUB and Kindle. Book excerpt: The first definitive work on the European Storm-petrel and its relatives, by one of the world's leading experts on the species. Imagine a bird as small as a sparrow, which lives most of its life on the open ocean yet can survive for decades. It walks on water, and migrates half way around the world, returning to remote islands to breed underground, often in the same rock crevice each year. At night it lays an enormous egg, feeding its chick until the nestling weighs more than both parents put together. It seems to have little fear of humans, but was itself feared by ancient seafarers. This might sound like the stuff of legend but is actually the description of a real creature, the storm-petrel: walker on water, global wanderer, climate sentinel and open-ocean survivor. In this beautifully written monograph, Rob Thomas explores the remarkable life of the European Storm-petrel, comparing and contrasting its behaviour and ecology across its range, and with the other storm-petrels of the world. We learn about their evolution, taxonomy, migration and adaptations to a life in the harsh open ocean, while also discovering what these enigmatic seabirds are revealing about what humans are doing to our planet. Illustrated with 150 photographs, and including the author's personal anecdotes and observations, Storm-petrels highlights some of the most exciting recent research findings and sets a trajectory for future discoveries.

Book excerpt: Bird flight has always intrigued mankind. This book provides an up to date account of our existing knowledge on the subject, as well as offering new insights and challenging some established views. A brief history of the science of flight introduces the basic physical principles governing aerial locomotion. A treatment of flight-related functional morphology concentrates on the difference in shape of the arm and hand part of the wings, on the structure and function of tails, and on the shape of the body. The anatomy and mechanical properties of feathers receive special attention. Aerodynamic principles used by birds are explained in theory by simply applying Newton's laws, and in practice by showing the direction and velocity of the attached flow around an arm wing cross section and of the leading edge vortex flow above a hand wing. The Archaeopteryx fossils remain crucial in our understanding of the evolution of bird flight despite the recent discovery of a range of well-preserved ancient birds. A novel insight into the interactions between wings and air challenges established theories relating to the origin of bird flight. Take-off, flapping flight, gliding and landing are the basic ingredients of bird flight, and birds use a variety of flight styles from hovering to soaring. Flight muscles consisting of mosaics of specialised fibres are the engines that generate the force required to keep the wings and tail in the gliding configuration and perform work during flapping motion. The energy required to fly can be estimated or measured directly, and a comparison of the empirical results provides insights into the trend in metabolic costs of flight of birds varying in shape and mass from hummingbirds to albatrosses.

Download or read book Comparative Biomechanics written by Steven Vogel and published by Princeton University Press. This book was released on 2013-06-17 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic textbook on comparative biomechanics—revised and expanded Why do you switch from walking to running at a specific speed? Why do tall trees rarely blow over in high winds? And why does a spore ejected into air at seventy miles per hour travel only a fraction of an inch? Comparative Biomechanics is the first and only textbook that takes a comprehensive look at the mechanical aspects of life—covering animals and plants, structure and movement, and solids and fluids. An ideal entry point into the ways living creatures interact with their immediate physical world, this revised and updated edition examines how the forms and activities of animals and plants reflect the materials available to nature, considers rules for fluid flow and structural design, and explores how organisms contend with environmental forces. Drawing on physics and mechanical engineering, Steven Vogel looks at how animals swim and fly, modes of terrestrial locomotion, organism responses to winds and water currents, circulatory and suspension-feeding systems, and the relationship between size and mechanical design. He also investigates links between the properties of biological materials—such as spider silk, jellyfish jelly, and muscle—and their structural and functional roles. Early chapters and appendices introduce relevant physical variables for quantification, and problem sets are provided at the end of each chapter. Comparative Biomechanics is useful for physical scientists and engineers seeking a guide to state-of-the-art biomechanics. For a wider audience, the textbook establishes the basic biological context for applied areas—including ergonomics, orthopedics, mechanical prosthetics, kinesiology, sports medicine, and biomimetics—and provides materials for exhibit designers at science museums. Problem sets at the ends of chapters Appendices cover basic background information Updated and expanded documentation and materials Revised figures and text Increased coverage of friction, viscoelastic materials, surface tension, diverse modes of locomotion, and biomimetics

Download or read book Principles of Animal Locomotion written by R. McNeill Alexander and published by Princeton University Press. This book was released on 2013-10-31 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.

Download or read book The Birds World written by Nicolae Sfetcu and published by MultiMedia Publishing. This book was released on 2014-11-27 with total page 1478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are among the most extensively studied of all animal groups. Hundreds of academic journals and thousands of scientists are devoted to bird research, while amateur enthusiasts (called birdwatchers or, more commonly, birders) probably number in the millions. Birds are categorised as a biological class, Aves. The earliest known species of this class is Archaeopteryx lithographica, from the Late Jurassic period. According to the most recent consensus, Aves and a sister group, the order Crocodilia, together form a group of unnamed rank, the Archosauria. Phylogenetically, Aves is usually defined as all descendants of the most recent common ancestor of modern birds (or of a specific modern bird species like Passer domesticus), and Archaeopteryx. Modern phylogenies place birds in the dinosaur clade Theropoda. Modern birds are divided into two superorders, the Paleognathae (mostly flightless birds like ostriches), and the wildly diverse Neognathae, containing all other birds.

Download or read book The Ptarmigan s Dilemma written by John Theberge and published by McClelland & Stewart. This book was released on 2011-04-05 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2010 Lane Anderson Award Drawing on breakthrough research in evolution, genetics, and on their extensive work in the field and lab, wildlife biologists John and Mary Theberge explain for non-scientists the real facts of life. Birds that suddenly grow gall bladders, when their species has none. Moose with antlers so big they encumber their movement through the forest. Butterflies that risk extinction by overwintering en masse. These are just a few stories the Theberges tell in their examination of what the mechanisms of evolution are and how they work. With examples from the very latest discoveries in genetics and ones they have made in their own field work, The Ptarmigan's Dilemma is a ground-breaking explanation of evolution for non-scientists. By marrying the separate sciences of ecology and genetics, the Theberges paint a picture far richer than either discipline can alone of how, for almost 4 billion years, life on Earth has evolved into the rich diversity that's under threat today. Along the way, they explain just what "the survival of the fittest" really means, how dramatic evolutionary changes can take place in just one generation, and how our too-little knowledge of or interest in how life on Earth organizes and supports itself is rapidly making us a danger to ourselves.

Book excerpt: Originally published in 1986, this book is concerned with the ways in which seabirds function as predators in the marine environment; in particular about how they find and catch food and how much of it they consume. It reviews both the feeding ecology of seabirds (including adaptations for flight and diving) and also most of the leading field studies (in polar, temperate and tropical regions) that have quantitatively examined the interactions of seabird communities with their prey.

Download or read book Birds in Their Habitats written by Ian Fraser and published by CSIRO PUBLISHING. This book was released on 2018-03-01 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everywhere we go there are birds, and they all have mysteries to be unravelled. These mysteries include the way they look, from bizarre to apparently mundane, why they live where they live, and the things they do, many of which are far too incredible ever to be imagined as fiction. Birds in Their Habitats is a collection of stories and experiences, which introduce fascinating aspects of birdlife, ecology and behaviour. Informed by a wealth of historical and contemporary research, Ian Fraser takes the reader on a journey through four continents: from places as unfamiliar as the Chonos Archipelago of southern Chile and the arid Sahel woodlands of northern Cameroon to those as familiar as a suburban backyard. This is a book of discovery of birds and the places they live. And with humour and personal insight, it is a book about the sometimes strange world of the people who spend a life absorbed in birds.
