Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Available in PDF, EPUB and Kindle. Book excerpt: “A soulful reckoning for our twenty-first century, held in focus through echoes of the past and future, but always firmly rooted in now.” —Yusef Komunyakaa, Pulitzer Prize-winning poet Winner of the Colorado Book Award in Poetry (2018) In this fourth book in a series of award-winning survival narratives, Dungy writes positioned at a fulcrum, bringing a new life into the world even as her elders are passing on. In a time of massive environmental degradation, violence and abuse of power, a world in which we all must survive, these poems resonate within and beyond the scope of the human realms, delicately balancing between conflicting loci of attention. Dwelling between vibrancy and its opposite, Dungy writes in a single poem about a mother, a daughter, Smokin’ Joe Frazier, brittle stars, giant boulders, and a dead blue whale. These poems are written in the face of despair to hold an impossible love and a commitment to hope. A readers companion will be available at wesleyan.edu/wespress/readerscompanions. “Dungy asks how we can survive despair and finds her answers close to the earth.” —Diana Whitney, The Kenyon Review “Trophic Cascade frequently bears witness—to violence, to loss, to environmental degradation—but for Dungy, witnessing entails hope.” —Julie Swarstad Johnson, Harvard Review Online “Tension. Simmering. Beneath her matter-of-fact, easy-going, sit-yourself-down, let-me-tell-it-like-it-is clarifying. And her power we take deadly seriously.” —Matt Sutherland, Foreword Reviews “[Trophic Cascade] asks us, in spite of the pain or difficulty of being human today, to find joy and vibrancy in our experiences.” —Elizabeth Flock, PBS Newshour

Download or read book Life Between the Tides written by Adam Nicolson and published by Farrar, Straus and Giroux. This book was released on 2022-02-22 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adam Nicolson explores the marine life inhabiting seashore rockpools with a scientist’s curiosity and a poet’s wonder in this beautifully illustrated book. The sea is not made of water. Creatures are its genes. Look down as you crouch over the shallows and you will find a periwinkle or a prawn, a claw-displaying crab or a cluster of anemones ready to meet you. No need for binoculars or special stalking skills: go to the rocks and the living will say hello. Inside each rock pool tucked into one of the infinite crevices of the tidal coastline lies a rippling, silent, unknowable universe. Below the stillness of the surface course different currents of endless motion—the ebb and flow of the tide, the steady forward propulsion of the passage of time, and the tiny lifetimes of the rock pool’s creatures, all of which coalesce into the grand narrative of evolution. In Life Between the Tides, Adam Nicolson investigates one of the most revelatory habitats on earth. Under his microscope, we see a prawn’s head become a medieval helmet and a group of “winkles” transform into a Dickensian social scene, with mollusks munching on Stilton and glancing at their pocket watches. Or, rather, is a winkle more like Achilles, an ancient hero, throwing himself toward death for the sake of glory? For Nicolson, who writes “with scientific rigor and a poet’s sense of wonder” (The American Scholar), the world of the rock pools is infinite and as intricate as our own. As Nicolson journeys between the tides, both in the pools he builds along the coast of Scotland and through the timeline of scientific discovery, he is accompanied by great thinkers—no one can escape the pull of the sea. We meet Virginia Woolf and her Waves; a young T. S. Eliot peering into his own rock pool in Massachusetts; even Nicolson’s father-in-law, a classical scholar who would hunt for amethysts along the shoreline, his mind on Heraclitus and the other philosophers of ancient Greece. And, of course, scientists populate the pages; not only their discoveries, but also their doubts and errors, their moments of quiet observation and their thrilling realizations. Everything is within the rock pools, where you can look beyond your own reflection and find the miraculous an inch beneath your nose. “The soul wants to be wet,” Heraclitus said in Ephesus twenty-five hundred years ago. This marvelous book demonstrates why it is so. Includes Color and Black-and-White Photographs

Available in PDF, EPUB and Kindle. Book excerpt: "Many of the findings in the book . . . are classics of ecology. . . . A rare and delightful insight into timely science."—Jane Lubchenco, Nature "Estes's refreshing narrative deftly weaves rigorous science with personal reflection to create an absorbing and introspective read that is equal parts memoir, ecological textbook, and motivational guidebook for young ecologists."—Science To newly minted biologist James Estes, the sea otters he was studying in the leafy kelp forests off the coast of Alaska appeared to have an unbalanced relationship with their greater environment. Gorging themselves on the sea urchins that grazed among the kelp, these small charismatic mammals seemed to give little back in return. But as Estes dug deeper, he unearthed a far more complex relationship between the otter and its underwater environment, discovering that otters play a critical role in driving positive ecosystem dynamics. While teasing out the connective threads, he began to question our assumptions about ecological relationships. These questions would ultimately inspire a lifelong quest to better understand the surprising complexity of our natural world and the unexpected ways we discover it. Serendipity tells the story of James Estes’s life as a naturalist and the concepts that have driven his interest in researching the ecological role of top-level predators. Using the relationships between sea otters, kelp, and sea urchins as a touchstone, Estes retraces his investigations of numerous other species, ecosystems, and ecological processes in an attempt to discover why ecologists can learn so many details about the systems in which they work and yet understand so little about the broader processes that influence these systems. Part memoir, part natural history, and deeply inquisitive, Serendipity will entertain and inform readers as it raises thoughtful questions about our relationship with the natural world.

Available in PDF, EPUB and Kindle. Book excerpt: INSTANT NEW YORK TIMES BESTSELLER "Blazing...Visceral" (Los Angeles Times) · "Exceptional" (Newsweek) · "Bold...Heartfelt" (New York Times Book Review) · "Thought-provoking and thrilling" (GMA) · "Suspenseful and poignant" (Scientific American) · "Gripping" (The Sydney Morning Herald) From the author of the beloved national bestseller Migrations, a pulse-pounding new novel set in the wild Scottish Highlands. Inti Flynn arrives in Scotland with her twin sister, Aggie, to lead a team of biologists tasked with reintroducing fourteen gray wolves into the remote Highlands. She hopes to heal not only the dying landscape, but Aggie, too, unmade by the terrible secrets that drove the sisters out of Alaska. Inti is not the woman she once was, either, changed by the harm she’s witnessed—inflicted by humans on both the wild and each other. Yet as the wolves surprise everyone by thriving, Inti begins to let her guard down, even opening herself up to the possibility of love. But when a farmer is found dead, Inti knows where the town will lay blame. Unable to accept her wolves could be responsible, Inti makes a reckless decision to protect them. But if the wolves didn’t make the kill, then who did? And what will Inti do when the man she is falling for seems to be the prime suspect? Propulsive and spell-binding, Charlotte McConaghy's Once There Were Wolves is the unforgettable story of a woman desperate to save the creatures she loves—if she isn’t consumed by a wild that was once her refuge.

Download or read book If Sharks Disappeared written by Lily Williams and published by Roaring Brook Press. This book was released on 2017-05-23 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A healthy ocean is home to many different kinds of animals. They can be big, like a whale, tiny, like a shrimp, and even scary, like a shark. Even though sharks can be scary, we need them to keep the oceans healthy. Unfortunately, due to overfishing, many shark species are in danger of extinction, and that can cause big problems in the oceans and even on land. What would happen if this continued and sharks disappeared completely? Artist Lily Williams explores how the disappearance would affect other animals across the whole planet in this clever book about the importance of keeping sharks, and our oceans, healthy.

Download or read book Large Herbivore Ecology Ecosystem Dynamics and Conservation written by Kjell Danell and published by Cambridge University Press. This book was released on 2006-05-25 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

Download or read book Black Nature written by Camille T. Dungy and published by University of Georgia Press. This book was released on 2009 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black Nature is the first anthology to focus on nature writing by African American poets, a genre that until now has not commonly been counted as one in which African American poets have participated. Black poets have a long tradition of incorporating treatments of the natural world into their work, but it is often read as political, historical, or protest poetry--anything but nature poetry. This is particularly true when the definition of what constitutes nature writing is limited to work about the pastoral or the wild. Camille T. Dungy has selected 180 poems from 93 poets that provide unique perspectives on American social and literary history to broaden our concept of nature poetry and African American poetics. This collection features major writers such as Phillis Wheatley, Rita Dove, Yusef Komunyakaa, Gwendolyn Brooks, Sterling Brown, Robert Hayden, Wanda Coleman, Natasha Trethewey, and Melvin B. Tolson as well as newer talents such as Douglas Kearney, Major Jackson, and Janice Harrington. Included are poets writing out of slavery, Reconstruction, the Harlem Renaissance, the Black Arts Movement, and late twentieth- and early twenty-first-century African American poetic movements. Black Nature brings to the fore a neglected and vital means of considering poetry by African Americans and nature-related poetry as a whole. A Friends Fund Publication.

Download or read book If You Take Away the Otter written by Susannah Buhrman-Deever and published by National Geographic Books. This book was released on 2020-05-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the sea otters disappear, why does their kelp forest habitat disappear, too? On the Pacific Coast of North America, sea otters play, dive, and hunt for sea urchins, crabs, abalone, and fish in the lush kelp forests beneath the waves. But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

Download or read book Effective Conservation Science written by Peter M. Kareiva and published by Oxford University Press. This book was released on 2018 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This novel text assembles some of the most intriguing voices in modern conservation biology. Collectively they highlight many of the most challenging questions being asked in conservation science today, each of which will benefit from new experiments, new data, and new analyses. The book's principal aim is to inspire readers to tackle these uncomfortable issues head-on. A second goal is to be reflective and consider how the field has reacted to challenges to orthodoxy, and to what extent have or can these challenges advance conservation science. Furthermore, several chapters discuss how to guard against confirmation bias. The overall goal is that this book will lead to greater conservation of ecosystems and biodiversity by harnessing the engine of constructive scientific scepticism in service of better results.

Download or read book Piper A Model Genus for Studies of Phytochemistry Ecology and Evolution written by Lee A. Dyer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Piper is an economically and ecologically important genus of plant that includes a fascinating array of species for studying natural history, natural products chemistry, community ecology, and evolutionary biology. The diversification of this taxon is unique and of great importance in understanding the evolution of plants. The diversity and ecological relevance of this genus makes it an obvious candidate for ecological and evolutionary studies, but surprisingly, most research on Piper spp. to-date has focused on the more economically important plants P. nigrum (black pepper), P. methysticum (kava), and P. betle (betel leaf). While this book does address the applied techniques of studying Piper, its focus is more on Piper in its natural setting. Piper: A Model Genus for Studies of Phytochemistry, Ecology, and Evolution synthesizes existing data and provides an outline for future investigations of the chemistry, ecology, and evolution of this taxon, while examining its key themes of Piper as a model genus for ecological and evolutionary studies, the important ecological roles of Piper species in lowland wet forests, and the evolution of distinctive Piper attributes. This volume has a place in the libraries of those studying or working in the fields of ecology, evolutionary biology, natural products chemistry, invasive species biology, pharmaceutics, and ethnobotany.
