| trophic cascades and keystone species answer key: Counting Species Rafi Youatt, 2015-02-14 Three decades of biodiversity governance has largely failed to stop the ongoing environmental crisis of global species loss. Yet that governance has resulted in undeniably important political outcomes. In Counting Species, Rafi Youatt argues that the understanding of global biodiversity has produced a distinct vision and politics of nature, one that is bound up with ideas about species, norms of efficiency, and apolitical forms of technical management. Since its inception in the 1980s, biodiversity’s political power has also hinged on its affiliation with a series of political concepts. Biodiversity was initially articulated as a moral crime against the intrinsic value of all species. In the 1990s and early 2000s, biodiversity shifted toward an association with service provision in a globalizing world economy before attaching itself more recently to the discourses of security and resilience. Even as species extinctions continue, biodiversity’s role in environmental governance has become increasingly abstract. Yet the power of global biodiversity is eventually always localized and material when it encounters nonhuman life. In these encounters, Youatt finds reasons for optimism, tracing some of the ways that nonhuman life has escaped human social means. Counting Species compellingly offers both a political account of global biodiversity and a unique approach to political agency across the human–nonhuman divide. |

| trophic cascades and keystone species answer key: Conservation by Proxy Tim Caro, 2010-06-23 The vast scope of conservation problems has forced biologists and managers to rely on surrogate species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively. |

| trophic cascades and keystone species answer key: The Serengeti Rules Sean B. Carroll, 2024-08-20 One of today's most accomplished biologists and gifted storytellers reveals the rules that regulate all life How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions, and shows how their discoveries matter for our health and the health of the planet we depend upon. One of the most important revelations about the natural world is that everything is regulated—there are rules that regulate the amount of every molecule in our bodies and rules that govern the numbers of every animal and plant in the wild. And the most surprising revelation about the rules that regulate life at such different scales is that they are remarkably similar—there is a common underlying logic of life. Carroll recounts how our deep knowledge of the rules and logic of the human body has spurred the advent of revolutionary life-saving medicines, and makes the compelling case that it is now time to use the Serengeti Rules to heal our ailing planet. Bold and inspiring, The Serengeti Rules illuminates how life works at vastly different scales. Read it and you will never look at the world the same way again. |
| trophic cascades and keystone species answer key: Serendipity James A. Estes, 2020-11-10 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. |

| trophic cascades and keystone species answer key: On the Zoological Geography of the Malay Archipelago Alfred Russel Wallace, 2016-05-25 This early work by Alfred Russel Wallace was originally published in 1859 and we are now republishing it with a brand new introductory biography. 'On the Zoological Geography of the Malay Archipelago' is an article detailing Wallace's observations during his travels in Asia. Alfred Russel Wallace was born on 8th January 1823 in the village of Llanbadoc, in Monmouthshire, Wales. Wallace was inspired by the travelling naturalists of the day and decided to begin his exploration career collecting specimens in the Amazon rainforest. He explored the Rio Negra for four years, making notes on the peoples and languages he encountered as well as the geography, flora, and fauna. While travelling, Wallace refined his thoughts about evolution and in 1858 he outlined his theory of natural selection in an article he sent to Charles Darwin. Wallace made a huge contribution to the natural sciences and he will continue to be remembered as one of the key figures in the development of evolutionary theory. |

| trophic cascades and keystone species answer key: Gene Drives on the Horizon National Academies of Sciences, Engineering, and Medicine, Division on Earth and Life Studies, Board on Life Sciences, Committee on Gene Drive Research in Non-Human Organisms: Recommendations for Responsible Conduct, 2016-08-28 Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators. |

| trophic cascades and keystone species answer key: The Economics of Ecosystems and Biodiversity: Ecological and Economic Foundations Pushpam Kumar, 2012-12-20 Human well-being relies critically on ecosystem services provided by nature. Examples include water and air quality regulation, nutrient cycling and decomposition, plant pollination and flood control, all of which are dependent on biodiversity. They are predominantly public goods with limited or no markets and do not command any price in the conventional economic system, so their loss is often not detected and continues unaddressed and unabated. This in turn not only impacts human well-being, but also seriously undermines the sustainability of the economic system. It is against this background that TEEB: The Economics of Ecosystems and Biodiversity project was set up in 2007 and led by the United Nations Environment Programme to provide a comprehensive global assessment of economic aspects of these issues. This book, written by a team of international experts, represents the scientific state of the art, providing a comprehensive assessment of the fundamental ecological and economic principles of measuring and valuing ecosystem services and biodiversity, and showing how these can be mainstreamed into public policies. This volume and subsequent TEEB outputs will provide the authoritative knowledge and guidance to drive forward the biodiversity conservation agenda for the next decade. |

| trophic cascades and keystone species answer key: Landscape Ecology in Theory and Practice Monica G. Turner, Robert H. Gardner, Robert V. O'Neill, 2007-05-08 An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading. |

| trophic cascades and keystone species answer key: The Yellowstone Wolf Paul Schullery, 2003 All royalties from sales of this book go to Yellowstone’s wolf recovery project Few animals inspire such a mixture of fear, curiosity, and wonder as the wolf. Highly regarded but often misunderstood, the wolf has as many friends as enemies, and its reintroduction into Yellowstone National Park has sparked both fascination and controversy. Early in Yellowstone’s history, wolves were thought supernaturally evil, and scores were destroyed. Northern Rocky Mountain wolves were native to Yellowstone when the park was established in 1872, but “predator control” led to determined eradication, and by the 1940s they were gone. Amid much fanfare, however, wolves were reintroduced to one of the nation’s oldest national parks in the 1990s. This comprehensive reference documents the prehistory, management, and nature of the Yellowstone wolf. Historian-naturalist Paul Schullery has assembled the voices of explorers, naturalists, park officials, tourists, lawmakers, and modern researchers to tell the story of what may be the most famous wolf population in the world. This unique book includes numerous scientific studies of interest to wolf enthusiasts and scholars of western wildlife issues, conservation, and national parks. In a new afterword, Schullery discusses recent developments in the recovery project. |
| trophic cascades and keystone species answer key: Complexity in Landscape Ecology David G. Green, Nicholas Klomp, Glyn Rimmington, Suzanne Sadedin, 2006-02-17 Interactions matter. To understand the distributions of plants and animals in a landscape you need to understand how they interact with each other, and with their environment. The resulting networks of interactions make ecosystems highly complex. Recent research on complexity and artificial life provides many new insights about patterns and processes in landscapes and ecosystems. This book provides the first overview of that work for general readers. It covers such topics as connectivity, criticality, feedback, and networks, as well as their impact on the stability and predictability of ecosystem dynamics. With over 60 years of research experience of both ecology and complexity, the authors are uniquely qualified to provide a new perspective on traditional ecology. They argue that understanding ecological complexity is crucial in today’s globalized and interconnected world. Successful management of the world's ecosystems needs to combine models of ecosystem complexity with biodiversity, environmental, geographic and socioeconomic information. |
| trophic cascades and keystone species answer key: Intertidal Ecology D. Raffaelli, S.J. Hawkins, 2012-12-06 The seashore has long been the subject of fascination and study - the Ancient Greek scholar Aristotle made observations and wrote about Mediterranean sea urchins. The considerable knowledge of what to eat and where it could be found has been passed down since prehistoric times by oral tradition in many societies - in Britain it is still unwise to eat shellfish in months without an 'r' in them. Over the last three hundred years or so we have seen the formalization of science and this of course has touched intertidal ecology. Linnaeus classified specimens collected from the seashore and many common species (Patella vulgata L. , Mytilus edulis L. , Littorina littorea (L. )) bear his imprint because he formally described, named and catalogued them. Early natural historians described zonation patterns in the first part of the 19th century (Audouin and Milne-Edwards, 1832), and the Victorians became avid admirers and collectors of shore animals and plants with the advent of the new fashion of seaside holidays (Gosse, 1856; Kingsley, 1856). As science became professionalized towards the end of the century, marine biologists took advantage of low tides to gain easy access to marine life for taxonomic work and classical studies of functional morphology. The first serious studies of the ecology of the shore were made at this time (e. g. |
| trophic cascades and keystone species answer key: Cephalopods Peter Boyle, Paul Rodhouse, 2008-04-15 Squid, cuttlefish and octopuses, which form the marine mollusc group the cephalopods, are of great and increasing interest to marine biologists, physiologists, ecologists, environmental biologists and fisheries scientists. Cephalopods: ecology and fisheries is a thorough review of this most important animal group. The first introductory section of the book provides coverage of cephalopod form and function, origin and evolution, Nautilus, and biodiversity and zoogeography. The following section covers life cycles, growth, physiological ecology, reproductive strategies and early life histories. There follows a section on ecology, which provides details of slope and shelf species, oceanic and deep sea species, population ecology, trophic ecology and cephalopods as prey. The final section of the book deals with fisheries and ecological interactions, with chapters on fishing methods and scientific sampling, fisheries resources, fisheries oceanography and assessment and management methods. This scientifically comprehensive and beautifully illustrated book is essential reading for marine biologists, zoologists, ecologists and fisheries managers. All libraries in universities and research establishments where biological sciences and fisheries are studied and taught should have multiple copies of this landmark publication on their shelves. |
