Download or read book Distance Sampling Methods and Applications written by S. T. Buckland and published by Springer. This book was released on 2015-08-08 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors cover the basic methods and advances within distance sampling that are most valuable to practitioners and in ecology more broadly. This is the fourth book dedicated to distance sampling. In the decade since the last book published, there have been a number of new developments. The intervening years have also shown which advances are of most use. This self-contained book covers topics from the previous publications, while also including recent developments in method, software and application. Distance sampling refers to a suite of methods, including line and point transect sampling, in which animal density or abundance is estimated from a sample of distances to detected individuals. The book illustrates these methods through case studies; data sets and computer code are supplied to readers through the book’s accompanying website. Some of the case studies use the software Distance, while others use R code. The book is in three parts. The first part addresses basic methods, the design of surveys, distance sampling experiments, field methods and data issues. The second part develops a range of modelling approaches for distance sampling data. The third part describes variations in the basic method; discusses special issues that arise when sampling different taxa (songbirds, seabirds, cetaceans, primates, ungulates, butterflies, and plants); considers advances to deal with failures of the key assumptions; and provides a check-list for those conducting surveys.

Download or read book Analysis of Vertebrate Populations written by Graeme Caughley and published by . This book was released on 2004-06 with total page 0 pages. Available in PDF, EPUB and Kindle. 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 Sampling of Populations written by Paul S. Levy and published by John Wiley & Sons. This book was released on 2013-06-07 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: A trusted classic on the key methods in population sampling—now in a modernized and expanded new edition Sampling of Populations, Fourth Edition continues to serve as an all-inclusive resource on the basic and most current practices in population sampling. Maintaining the clear and accessible style of the previous edition, this book outlines the essential statistical methodsfor survey design and analysis, while also exploring techniques that have developed over the past decade. The Fourth Edition successfully guides the reader through the basic concepts and procedures that accompany real-world sample surveys, such as sampling designs, problems of missing data, statistical analysis of multistage sampling data, and nonresponse and poststratification adjustment procedures. Rather than employ a heavily mathematical approach, the authors present illustrative examples that demonstrate the rationale behind common steps in the sampling process, from creating effective surveys to analyzing collected data. Along with established methods, modern topics are treated through the book's new features, which include: A new chapter on telephone sampling, with coverage of declining response rates, the creation of "do not call" lists, and the growing use of cellular phones A new chapter on sample weighting that focuses on adjustments to weight for nonresponse, frame deficiencies, and the effects of estimator instability An updated discussion of sample survey data analysis that includes analytic procedures for estimation and hypothesis testing A new section on Chromy's widely used method of taking probability proportional to size samples with minimum replacement of primary sampling units An expanded index with references on the latest research in the field All of the book's examples and exercises can be easily worked out using various software packages including SAS, STATA, and SUDAAN, and an extensive FTP site contains additional data sets. With its comprehensive presentation and wealth of relevant examples, Sampling of Populations, Fourth Edition is an ideal book for courses on survey sampling at the upper-undergraduate and graduate levels. It is also a valuable reference for practicing statisticians who would like to refresh their knowledge of sampling techniques.

This book was released on 2013-09-04 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.
