Book excerpt: This book was first published in 1977 and is widely recognized as a classic in the field. It is the "bible" for wildlife managers everywhere. It is an introduction to the methods and analysis of vertebrate populations for ecologists and wildlife managers as well as students of these subjects. A wide range of examples drawn from mammals and birds in different parts of the world is used to illustrate these methods. The book shows how population analysis can be applied to practical problems of wildlife management such as reducing a population, stimulating it to increase or taking from it a sustained yield. In order to make this complex subject as simple as possible, the methods for analysis described in this book are those which use elementary algebra and statistics rather than complex mathematics. Graeme Caughley studied the interactions between large mammalian herbivores and the environments they occupy. The pattern of population growth that can be predicted theoretically from such a relationship is both complex and variable. The animals will either erupt, crash, and then converge to a more stable density, or the population may oscillate indefinitely, the densities of plants and animals being locked into a stable limit cycle. He argued that the dynamics of mammalian herbivore populations are comprehensible only in terms of an interactive relationship between the herbivores and vegetation. He further argued that efficient management of such systems requires an understanding of the underlying mechanisms whereby the animals react to the plants and in turn the plants react dynamically to the effects of grazing. He was best known for his contributions to the understanding of herbivore-vegetation dynamics in the New Zealand high country, the Himalayas, southern Africa and the semi-arid rangelands of Australia. His research was distinguished by rigorous design, execution and analysis, so that the conclusions had generality beyond the particular species studied. Since he chose topics that combined theoretical interest and practical application, he also influenced important management policies - deer populations in New Zealand, kangaroos in Australia and the conservation of large mammals in Africa and North America. He had a major influence on thinking and practice in the field of vertebrate ecology and wildlife management throughout the world.

Download or read book Quantitative Conservation of Vertebrates written by Michael J. Conroy and published by John Wiley & Sons. This book was released on 2011-09-20 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a hands-on introduction to the construction and application of models to studies of vertebrate distribution, abundance, and habitat. The book is aimed at field biologists, conservation planners, and advanced undergraduate and postgraduate students who are involved with planning and analyzing conservation studies, and applying the results to conservation decisions. The book also acts as a bridge to more advanced and mathematically challenging coverage in the wider literature. Part I provides a basic background in population and community modeling. It introduces statistical models, and familiarizes the reader with important concepts in the design of monitoring and research programs. These programs provide the essential data that guide conservation decision making. Part II covers the principal methods used to estimate abundance, occupancy, demographic parameters, and community parameters, including occupancy sampling, sample counts, distance sampling, and capture-mark-recapture (for both closed and open populations). Emphasis is placed on practical aspects of designing and implementing field studies, and the proper analysis of data. Part III introduces structured decision making and adaptive management, in which predictive models are used to inform conservation decision makers on appropriate decisions in the face of uncertainty—with the goal of reducing uncertainty through monitoring and research. A detailed case study is used to illustrate each of these themes. Numerous worked examples and accompanying electronic material (on a website - http://www.blackwellpublishing.com/conroy - and accompanying CD) provide the details of model construction and application, and data analysis.

Download or read book Major Patterns in Vertebrate Evolution written by Max Hecht and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the result of a NATO Advanced Study Institute held in England at Kingswood Hall of Residence, Royal Holloway College (London University), Surrey, during the last two weeks of July, 1976. The ASI was organized within the guide lines laid down by the Scientific Affairs Division of the North Atlantic Treaty Organization. During the past two decades, significant advances have been made in our understanding of vertebrate evolution. The purpose of the Institute was to present the current status of our know ledge of vertebrate evolution above the species level. Since the subject matter was obviously too broad to be covered adequately in the limited time available, selected topics, problems, and areas which are applicable to vertebrate zoology as a whole were reviewed. The program was divided into three areas: (1) the theory and methodology of phyletic inference and approaches to the an alysis of macroevolutionary trends as applied to vertebrates; (2) the application of these methodological principles and an alytical processes to different groups and structures, particular ly in anatomy and paleontology; (3) the application of these re sults to classification. The basic principles considered in the first area were outlined in lectures covering the problems of character analysis, functional morphology, karyological evidence, biochemical evidence, morphogenesis, and biogeography.

This book was released on 2013-11-11 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predation, one of the most dramatic interactions in animals' lives, has long fascinated ecologists. This volume presents carnivores, raptors and their prey in the complicated net of interrelationships, and shows them against the background of their biotic and abiotic settings. It is based on long-term research conducted in the best preserved woodland of Europe's temperate zone. The role of predation, whether limiting or regulating prey (ungulate, rodent, shrew, bird, and amphibian) populations, is quantified and compared to parts played by other factors: climate, food resources for prey, and availability of other potential resources for predators.

Download or read book Monitoring Animal Populations and Their Habitats written by Brenda C. McComb and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We designed this book to offer a comprehensive overview of the monitoring process, from start to finish. Although there are books that deal with sampling design and the quantitative analysis of population data, there are few that provide practical advice covering the entire evolution of a monitoring plan from incorporating stakeholder input to data collection to data management and analysis to reporting. This book strives to present an overview of this process. We also acknowledge that any such effort tends to reflect the interests and expertise of the authors, and as such, there is a distinct emphasis on monitoring vertebrate populations and upland habitats. Although many of our examples tend to focus on bird populations and forested habitats, we have made an attempt to cover other taxa and habitat types as well, and many of the recommendations and suggestions that we present are applicable to a diversity of monitoring programs. This book was written to fill a practical need and also to embrace a set of values that we hold dear. We wanted a book that could be used in a classroom because we feel that students in natural resources programs need to know how to design a monitoring program when they enter the workforce. We also realize that many former students now in the workforce did not have that training and may find this book of value to them.

Available in PDF, EPUB and Kindle. Book excerpt: In the face of so many unprecedented changes in our environment, the pressure is on scientists to lead the way toward a more sustainable future. Written by a team of ecologists, Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide provides a framework that natural resource managers and researchers can use to design monitoring programs that will benefit future generations by distilling the information needed to make informed decisions. In addition, this text is valuable for undergraduate- and graduate-level courses that are focused on monitoring animal populations. With the aid of more than 90 illustrations and a four-page color insert, this book offers practical guidance for the entire monitoring process, from incorporating stakeholder input and data collection, to data management, analysis, and reporting. It establishes the basis for why, what, how, where, and when monitoring should be conducted; describes how to analyze and interpret the data; explains how to budget for monitoring efforts; and discusses how to assemble reports of use in decision-making. The book takes a multi-scaled and multi-taxa approach, focusing on monitoring vertebrate populations and upland habitats, but the recommendations and suggestions presented are applicable to a variety of monitoring programs. Lastly, the book explores the future of monitoring techniques, enabling researchers to better plan for the future of wildlife populations and their habitats. Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide furthers the goal of achieving a world in which biodiversity is allowed to evolve and flourish in the face of such uncertainties as climate change, invasive species proliferation, land use expansion, and population growth.

Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.
