Download or read book Advanced Distance Sampling written by S. T. Buckland and published by OUP Oxford. This book was released on 2004-08-19 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001). In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring programme; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed.

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 Best Practice Guidelines for the Surveys and Monitoring of Great Ape Populations written by and published by IUCN. This book was released on 2008 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the website: The IUCN/SSC Primate Specialist Group is publishing new guidelines for surveys and monitoring of great ape populations. These guidelines address a need which has existed since great ape studies began -- the challenge of collecting consistently high-quality data for comparison between a wide variety of sites, and often across many years. This need is driven less by academic interest than by the urgent demands of field-based conservation. The maelstrom of threats which now endanger all the great apes must be addressed by immediate action on every scale: initiatives at individual sites, strategies on the regional and national level, and species-wide action plans and international accords. All of these efforts must be founded on accurate field data -- and to fully understand the impact of specific threats, and to measure if conservation programs are succeeding, it is essential to have baseline density estimates and sustained monitoring of great ape populations. The newest publication in the Best Practice series outlines current approaches to these issues, offering guidance and perspective on choices that must be made by wildlife biologists, site managers, government agencies and the conservation community at large. This report provides an overview of the variety of survey methodologies that have been developed, as well as a decision tree to help select the approach that is best for a particular site or situation, depending on available resources. As a continuation of this report, a series of modules will be made available online, which will present detailed information on survey design, field techniques, analytical approaches, and practical issues such as logistics, finance and standardized reporting. These new IUCN guidelines will help researchers to standardize their data collection and, just as importantly, will allow for improved comparisons between datasets. This will complement the A.P.E.S. database (http://apes.eva.mpg.de), which is intended to serve as a repository for survey data on great apes, and to analyze trends in their populations. These survey and monitoring guidelines, combined with resources available via A.P.E.S., are important steps towards a comprehensive understanding of the conservation status of great apes, at both the population and species level. .
