Book Synopsis Sampling Rare or Elusive Species by : William Thompson

Download or read book Sampling Rare or Elusive Species written by William Thompson. This book was released on 2013-04-10. Available in PDF, EPUB and Kindle. Book excerpt: Information regarding population status and abundance of rare species plays a key role in resource management decisions. Ideally, data should be collected using statistically sound sampling methods, but by their very nature, rare or elusive species pose a difficult sampling challenge. Sampling Rare or Elusive Species describes the latest sampling designs and survey methods for reliably estimating occupancy, abundance, and other population parameters of rare, elusive, or otherwise hard-to-detect plants and animals. It offers a mixture of theory and application, with actual examples from terrestrial, aquatic, and marine habitats around the world. Sampling Rare or Elusive Species is the first volume devoted entirely to this topic and provides natural resource professionals with a suite of innovative approaches to gathering population status and trend data. It represents an invaluable reference for natural resource professionals around the world, including fish and wildlife biologists, ecologists, biometricians, natural resource managers, and all others whose work or research involves rare or elusive species.

Book Synopsis Wildlife Study Design by : Michael L. Morrison

Download or read book Wildlife Study Design written by Michael L. Morrison. This book was released on 2008-05-25. Available in PDF, EPUB and Kindle. Book excerpt: We developed the first edition of this book because we perceived a need for a compilation on study design with application to studies of the ecology, conser- tion, and management of wildlife. We felt that the need for coverage of study design in one source was strong, and although a few books and monographs existed on some of the topics that we covered, no single work attempted to synthesize the many facets of wildlife study design. We decided to develop this second edition because our original goal – synthesis of study design – remains strong, and because we each gathered a substantial body of new material with which we could update and expand each chapter. Several of us also used the first edition as the basis for workshops and graduate teaching, which provided us with many valuable suggestions from readers on how to improve the text. In particular, Morrison received a detailed review from the graduate s- dents in his “Wildlife Study Design” course at Texas A&M University. We also paid heed to the reviews of the first edition that appeared in the literature.

Book Synopsis Estimating Presence and Abundance of Closed Populations by : George A. F. Seber

Download or read book Estimating Presence and Abundance of Closed Populations written by George A. F. Seber. This book was released on 2024-01-02. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive book covers a wide variety of methods for estimating the sizes and related parameters of closed populations. With the effect of climate change, and human territory invasion, we have seen huge species losses and a major biodiversity decline. Populations include plants, trees, various land and sea animals, and some human populations. With such a diversity of populations, an extensive variety of different methods are described with the collection of different types of data. For example, we have count data from plot sampling, which can also allow for incomplete detection. There is a large chapter on occupancy methods where a major interest is determining whether a particular species is present or not. Citizen and opportunistic survey data can also be incorporated. A related topic is species methods, where species richness and species' interactions are of interest. A variety of distance methods are discussed. One can use distances from points and lines, as well as nearest neighbor distances. The applications are extensive, and include marine, acoustic, and aerial surveys, using multiple observers or detection devices. Line intercept measurements have a role to play such as, for example, estimating parameters relating to plant coverage. An increasingly important class of removal methods considers successive “removals" from a population, with physical removal or "removal" by capture-recapture of marked individuals. With the change-in-ratio method, removals are taken from two or more classes, e.g., males and females. Effort data used for removals can also be used. A very important method for estimating abundance is the use of capture-recapture data collected discretely or continuously and can be analysed using both frequency and Bayesian methods. Computational aspects of fitting Bayesian models are described. A related topic of growing interest is the use of spatial and camera methods. With the plethora of models there has been a corresponding development of various computational methods and packages, which are often mentioned throughout. Covariate data is being used more frequently, which can reduce the number of unknown parameters by using logistic and loglinear models. An important computational aspect is that of model selection methods. The book provides a useful list of over 1400 references.

Download or read book Conservation of Rare or Little-Known Species written by Martin G. Raphael. This book was released on 2013-03-19. Available in PDF, EPUB and Kindle. Book excerpt: Some ecosystem management plans established by state and federal agencies have begun to shift their focus away from single-species conservation to a broader goal of protecting a wide range of flora and fauna, including species whose numbers are scarce or about which there is little scientific understanding. To date, these efforts have proved extremely costly and complex to implement. Are there alternative approaches to protecting rare or little-known species that can be more effective and less burdensome than current efforts? Conservation of Rare or Little-Known Species represents the first comprehensive scientific evaluation of approaches and management options for protecting rare or little-known terrestrial species. The book brings together leading ecologists, biologists, botanists, economists, and sociologists to classify approaches, summarize their theoretical and conceptual foundations, evaluate their efficacy, and review how each has been used. Contributors consider combinations of species and systems approaches for overall effectiveness in meeting conservation and ecosystem sustainability goals. They discuss the biological, legal, sociological, political, administrative, and economic dimensions by which conservation strategies can be gauged, in an effort to help managers determine which strategy or combination of strategies is most likely to meet their needs. Contributors also discuss practical considerations of implementing various strategies. Conservation of Rare or Little-Known Species gives land managers access to a diverse literature and provides them with the basic information they need to select approaches that best suit their conservation objectives and ecological context. It is an important new work for anyone involved with developing land management or conservation plans.
