Biodiversity of Semiarid Landscape


Book Description

This study presents authentic data compiled from field experiments and investigations, and provides a point of reference for any future changes associated with anthropogenic activity in semiarid ecosystems. Three years of continuous and rigorous empirical research on biodiversity (from phytoplankton to higher plants and from zooplankton to higher animals – all flora and fauna) in India’s semiarid region have culminated in this work. Though there are many studies available on issues related to biodiversity, the majority cover either specific groups of plants or groups of animals; with the exception of this book, studies that include all flora and fauna including the phyto- and zooplanktons in a given ecosystem are not readily available. Further, the book focuses on an extremely important topic, firstly because semiarid landscapes are highly vulnerable to climate change, and secondly because other developmental activities will be undertaken in the region in an effort to meet its energy requirements. As such, the results of the current study will provide a standard protocol for subsequent monitoring and mapping of biodiversity for conservation and management. The book explores, quantifies and surveys plant and animal species from aquatic and terrestrial ecosystems, assessing and quantitatively analyzing the diversity indices of different vegetation strata. Further, it investigates the conservation status of each species (flora and fauna) in keeping with IUCN categories. The study also examines landscape dynamics using RS and GIS for vegetation analysis, and discusses traditional ecological knowledge related to the use, conservation and management of biodiversity. As such, it offers a unique and valuable resource not only for researchers from the environmental/ecological sciences but also for conservationists and policymakers.




Biodiversity Baseline Assessment


Book Description

This report presents a biodiversity baseline assessment of areas at the Phipsoo Wildlife Sanctuary in southern Bhutan. This biodiversity baseline assessment was conducted in 2014?2015 at the Phipsoo Wildlife Sanctuary in southern Bhutan. Inventory and sampling of tree, avian, mammal, and fish species was accomplished in three areas. Grassland conditions and illegal tree harvesting were quantified. The assessment confirmed the presence of 27 protected species. Mammals accounted for the majority at 74%. Camera trapping over 5 months yielded 4,300 individual mammals and 28 species. Mammalian biodiversity metrics differed significantly among assessment zones. The elephant was the species most documented. The sanctuary was found to be a critical habitat for the endangered tiger and the critically endangered white bellied heron.




Conserving Biodiversity


Book Description

The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.







The Baseline Concept in Biodiversity Conservation


Book Description

The Anthropocene era has been marked by such significant human pressure that it has led to the sixth mass extinction. The Baseline Concept in Biodiversity Conservation interprets human domination of the Earth as the process of gradual landscape change, the execution of which is neither linear nor homogeneous. This book is structured around three key questions: Where and when did everything go wrong? How do we define baseline states for biodiversity conservation strategies? How are reference states mobilized in a concrete way through case studies? Today, biodiversity conservation faces a dilemma that this book sheds light on: return to states less modified by humans than today but in a world that has changed significantly; or, let the nature of tomorrow express itself where it still can but without a road map.




Handbook of Biodiversity Methods


Book Description

This Handbook, first published in 2005, provides standard procedures for planning and conducting a survey of any species or habitat and for evaluating the data.




Understanding Marine Biodiversity


Book Description

The diversity of marine life is being affected dramatically by fishery operations, chemical pollution and eutrophication, alteration of physical habitat, exotic species invasion, and effects of other human activities. Effective solutions will require an expanded understanding of the patterns and processes that control the diversity of life in the sea. Understanding Marine Biodiversity outlines the current state of our knowledge, and propose research agenda on marine biological diversity. This agenda represents a fundamental change in studying the oceanâ€"emphasizing regional research across a range of space and time scales, enhancing the interface between taxonomy and ecology, and linking oceanographic and ecological approaches. Highlighted with examples and brief case studies, this volume illustrates the depth and breadth of undescribed marine biodiversity, explores critical environmental issues, advocates the use of regionally defined model systems, and identifies a series of key biodiversity research questions. The authors examine the utility of various research approachesâ€"theory and modeling, retrospective analysis, integration of biotic and oceanographic surveysâ€"and review recent advances in molecular genetics, instrumentation, and sampling techniques applicable to the research agenda. Throughout the book the critical role of taxonomy is emphasized. Informative to the scientist and accessible to the policymaker, Understanding Marine Biodiversity will be of specific interest to marine biologists, ecologists, oceanographers, and research administrators, and to government agencies responsible for utilizing, managing, and protecting the oceans.

Environmental DNA


Book Description

Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.




Shifting Baselines


Book Description

Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.
