Book excerpt: Melanism: Evolution in Action describes investigations into a ubiquitous biological phenomenon, the existence of dark, or melanic, forms of many species of mammals, insects, and some plants. Melanism is a particularly exciting phenomenon in terms of our understanding of evolution. Unlike manyother polymorphisms, the rise of a melanic population within a species is a visible alteration. Not only this, but melanism may sometimes occur dramatically quickly compared to other evolutionary change. Examples of melanism include one of the most famous illustrations of Darwinian naturalselection, the peppered moth. This book, the first written on melanism since 1973, gives a lucid and up-to-date appraisal of the subject. The book is divided into ten chapters. The first four chapters place melanism into its historical and scientific context, with illustrations of its occurrence,and physical and genetic properties. Chapters 5-9 look in more detail at melanism in moths and ladybirds, explaining the diversity of evolutionary reasons for melanism, and the complexities underlying this apparently simple phenomenon. The final chapter shows how the study of melanism has contibutedto our understanding of biological evolution as a whole. Written in an engaging and readable style, by an author whose enthusiasm and depth of knowledge is apparent throughout, this book will be welcomed by all students and researchers in the fields of evolution, ecology, entomology, and genetics.It will also be of relevance to professional and amateur entomologists and lepidopterists alike.

Book excerpt: In this revelatory work, Judith Hooper uncovers the intellectual rivalries, petty jealousies, and flawed science behind one of the most famous experiments in evolutionary biology. Bernard Kettlewell's 1953 experiment on the peppered moths of England made him a media star on the order of Jonas Salk -- but also an unlikely tragic hero. As Hooper recounts in this rollicking scientific detective story, the truth can be subverted when the stakes are very high. Book jacket.

Download or read book The Black Leopard written by Will Burrard-Lucas and published by Chronicle Books. This book was released on 2021-04-20 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This inspiring book tells the story of a photographer's journey to find the mysterious black leopard. There are few creatures as gorgeous and elusive as the black leopard. In Africa, these magnificent cats are so rare as to be the stuff of legend. Will Burrard-Lucas's love for leopards began during his childhood in Tanzania and propelled him into a career as a wildlife photographer. In his quest to create intimate portraits of animals, he developed innovative technology, including a remotely controlled camera buggy and a high quality camera trap system for photographing nocturnal creatures. Then, one day in 2018, he heard about sightings of a young African black leopard in Kenya and with the help of people from the local community, he succeeded in capturing a series of high-quality photographs of the elusive cat. In this compelling and visually stunning book, Burrard-Lucas tells his story of creativity, entrepreneurship, and passion for wild animals, alongside awe-inspiring images of lions, elephants, and the black leopard itself. • STAR WILDLIFE PHOTOGRAPHER: Will Burrard-Lucas's passion for nature and expertise in camera technology have earned him coverage from National Geographic, The New York Times, and the BBC—and over 1 million fans enjoy his breathtaking work online. • NATURE'S HIDDEN WONDERS: Black leopards are individual animals in whom a gene mutation results in excess melanin and an elegant black coat. Most are found in Southeast Asia, where lush vegetation offers them camouflage. In the semiarid shrub lands of Africa, black leopards are extraordinarily rare. Burrard-Lucas's images—showing these beautiful creatures prowling their territory under cover of night—are vivid reminders of nature's hidden wonders. • INCREDIBLE STORY: This is an adventure story that takes place in remote and wild corners of Africa. It reveals Burrard-Lucas's devotion, vision, and innovation that led to him capturing photos that are not only incredibly rare, but also breathtakingly beautiful. Perfect for: • Aspiring and professional photographers • Photography buffs • Nature and animal lovers • Big cat enthusiasts • Conservationists • National Geographic readers • Fans of memoir and adventure stories • Travelers to Eastern and Southern Africa
Download or read book Darwin Comes to Town written by Menno Schilthuizen and published by Picador. This book was released on 2018-04-03 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: *Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts. *Lizards in Puerto Rico are evolving feet that better grip surfaces like concrete. *Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heardover the din of traffic. How is this happening? Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be. With human populations growing, we’re having an increasing impact on global ecosystems, and nowhere do these impacts overlap as much as they do in cities. The urban environment is about as extreme as it gets, and the wild animals and plants that live side-by-side with us need to adapt to a whole suite of challenging conditions: they must manage in the city’s hotter climate (the “urban heat island”); they need to be able to live either in the semidesert of the tall, rocky, and cavernous structures we call buildings or in the pocket-like oases of city parks (which pose their own dangers, including smog and free-rangingdogs and cats); traffic causes continuous noise, a mist of fine dust particles, and barriers to movement for any animal that cannot fly or burrow; food sources are mainly human-derived. And yet, as Schilthuizen shows, the wildlife sharing these spaces with us is not just surviving, but evolving ways of thriving. Darwin Comes toTown draws on eye-popping examples of adaptation to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward over population might not take the rest of nature down with us.

Download or read book EVOLUTION written by Michael Ruse and published by Harvard University Press. This book was released on 2009-01-01 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spanning evolutionary science from its inception to its latest findings, from discoveries and data to philosophy and history, this book is the most complete, authoritative, and inviting one-volume introduction to evolutionary biology available. Clear, informative, and comprehensive in scope, Evolution opens with a series of major essays dealing with the history and philosophy of evolutionary biology, with major empirical and theoretical questions in the science, from speciation to adaptation, from paleontology to evolutionary development (evo devo), and concluding with essays on the social and political significance of evolutionary biology today. A second encyclopedic section travels the spectrum of topics in evolution with concise, informative, and accessible entries on individuals from Aristotle and Linneaus to Louis Leakey and Jean Lamarck; from T. H. Huxley and E. O. Wilson to Joseph Felsenstein and Motoo Kimura; and on subjects from altruism and amphibians to evolutionary psychology and Piltdown Man to the Scopes trial and social Darwinism. Readers will find the latest word on the history and philosophy of evolution, the nuances of the science itself, and the intricate interplay among evolutionary study, religion, philosophy, and society. Appearing at the beginning of the Darwin Year of 2009Ñthe 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of the Origin of SpeciesÑthis volume is a fitting tribute to the science Darwin set in motion.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-11 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
