Chapter 7 - Conservation - Biology


  • 7.1: Ecological Value
  • 7.2: Threats to Biodiversity
  • 7.3: Preserving Biodiversity
  • 7.4: Extinction
    Extinction (the complete disappearance of a species from Earth) is an important part of the evolution of life on Earth. The current diversity of species is a product of the processes of extinction and speciation throughout the previous 3.8 billion year history of life. There might be 40 million species alive today, but between 5 and 50 billion species have lived at some time during the history of the Earth.

The practice of protecting wildlife species and their habitats to maintain healthy wildlife species and stop them from getting extinct is called wildlife conservation. In simple words, the conservation of plants and animals. This practice involves restoring, protecting and enhancing activities to maintain a natural ecosystem.

In class 8 science chapter 7 ‘Conservation of Plants and Animals,’ there are numbers of essential informative topics that have been covered. Although students must prepare this lesson from other study materials as well, this PDF file will help the students to grasp the concept easily. NCERT solutions for class 8 science chapter 7 are one such PDF which students must read for their exams. You can also download Class 8 Maths to score more marks in the examinations.

Abstract

Global biodiversity losses continue despite tremendous growth in the volume of conservation science and many local successes. Research that can achieve conservation science's aims—arresting declines in biodiversity and preventing extinctions—is therefore of ever greater importance. Here, we ask whether conservation science, as currently performed, is progressing in such a way as to maximize its impact. We present a simple framework for how effective conservation research could progress, from identifying problems to diagnosing their proximate and ultimate causes, and from proposing, to designing, implementing, and testing responses. We then demonstrate that for three well-known examples—South Asian vultures, whooping cranes, and bycatch of procellariform seabirds—published studies appear to follow this sequence, with considerable benefits. However, for a representative sample of the wider conservation literature, we find no evidence of such a progression. Instead, the vast majority of papers remain focused on describing the state of nature or on mechanisms directly causing changes, with very little research on designing or implementing conservation responses. This lack of research on the sorts of questions that might most help conservation science deliver its stated mission strongly suggests we will struggle to translate the huge increase in research activity into real-world benefits.


Marine Conservation Biology

Humans are terrestrial animals, and our capacity to see and understand the importance and vulnerability of life in the sea has trailed our growing ability to harm it. While conservation biologists are working to address environmental problems humans have created on land, loss of marine biodiversity, including extinctions and habitat degradation, has received much less attention. At the same time, marine sciences such as oceanography and fisheries biology have largely ignored issues of conservation.

Marine Conservation Biology brings together for the first time in a single volume, leading experts from around the world to apply the lessons and thinking of conservation biology to marine issues. Contributors including James M. Acheson, Louis W. Botsford, James T. Carlton, Kristina Gjerde, Selina S. Heppell, Ransom A. Myers, Julia K. Parrish, Stephen R. Palumbi, and Daniel Pauly offer penetrating insights on the nature of marine biodiversity, what threatens it, and what humans can and must do to recover the biological integrity of the world's estuaries, coastal seas, and oceans.

Sections examine: distinctive aspects of marine populations and ecosystems threats to marine biological diversity, singly and in combination place-based management of marine ecosystems the often-neglected human dimensions of marine conservation.

Marine Conservation Biology breaks new ground by creating the conceptual framework for the new field of marine conservation biology -- the science of protecting, recovering, and sustainably using the living sea. It synthesizes the latest knowledge and ideas from leading thinkers in disciplines ranging from larval biology to sociology, making it a must-read for research and teaching faculty, postdoctoral fellows, and graduate and advanced undergraduate students (who share an interest in bringing conservation biology to marine issues). Likewise, its lucid scientific examinations illuminate key issues facing environmental managers, policymakers, advocates, and funders concerned with the health of our oceans.

"With a focus that includes solutions as well as problems, this book is a timely and valuable reference for students, scientists, and conservationists."
Southeastern Naturalist

"Finally, there is a book that focuses on solutions in addition to issues and threats, and addresses crucial topics, including place-based management of marine ecosystems and the legal and ethical frameworks for ocean policy with depths, scholarship, and courage. This is a wonderful resource for learning, teaching, and inspiration."
Fiorenza Micheli, Assistant Professor at Hopkins Marine Station, Stanford University

Key Topics in Conservation Biology 2

Following the much acclaimed success of the first volume of Key Topics in Conservation Biology, this entirely new second volume addresses an innovative array of key topics in contemporary conservation biology. Written by an internationally renowned team of authors, Key Topics in Conservation Biology 2 adds to the still topical foundations laid in the first volume (published in 2007) by exploring a further 25 cutting-edge issues in modern biodiversity conservation, including controversial subjects such as setting conservation priorities, balancing the focus on species and ecosystems, and financial mechanisms to value biodiversity and pay for its conservation. Other chapters, setting the framework for conservation, address the sociology and philosophy of peoples’ relation with Nature and its impact on health, and such challenging practical issues as wildlife trade and conflict between people and carnivores. As a new development, this second volume of Key Topics includes chapters on major ecosystems, such as forests, islands and both fresh and marine waters, along with case studies of the conservation of major taxa: plants, butterflies, birds and mammals. A further selection of topics consider how to safeguard the future through monitoring, reserve planning, corridors and connectivity, together with approaches to reintroduction and re-wilding, along with managing wildlife disease. A final chapter, by the editors, synthesises thinking on the relationship between biodiversity conservation and human development.

Each topic is explored by a team of top international experts, assembled to bring their own cross-cutting knowledge to a penetrating synthesis of the issues from both theoretical and practical perspectives.

The interdisciplinary nature of biodiversity conservation is reflected throughout the book. Each essay examines the fundamental principles of the topic, the methodologies involved and, crucially, the human dimension. In this way, Key Topics in Conservation Biology 2, like its sister volume, Key Topics in Conservation Biology, embraces issues from cutting-edge ecological science to policy, environmental economics, governance, ethics, and the practical issues of implementation.

Key Topics in Conservation Biology 2 will, like its sister volume, be a valuable resource in universities and colleges, government departments, and conservation agencies. It is aimed particularly at senior undergraduate and graduate students in conservation biology and wildlife management and wider ecological and environmental subjects, and those taking Masters degrees in any field relevant to conservation and the environment. Conservation practitioners, policy-makers, and the wider general public eager to understand more about important environmental issues will also find this book invaluable.

Reviews

“The synthesis chapter is one of the highlights of this valuable multidisciplinary contribution to the field of conservation biology and should be mandatory reading material for both students of conservation biology and policymakers.” (Quarterly Review Biology, 1 March 2015)
