Available in PDF, EPUB and Kindle. Book excerpt: This book addresses issues of monitoring populations of tigers, ungulate prey species and habitat occupancy, with relevance to similar assessments of large mammal species and general biodiversity. It covers issues of rigorous sampling, modeling, estimation and adaptive management of animal populations using cutting-edge tools, such as camera-traps, genetic identification and Geographic Information Systems (GIS), applied under the modern statistical approach of Bayesian and likelihood-based inference. Of special focus here are animal survey data derived for use under spatial capture-recapture, occupancy, distance sampling, mixture-modeling and connectivity analysees. Because tigers are an icons of global conservation, in last five decades,enormous amounts of commitment and resources have been invested by tiger range countries and the conservation community for saving wild tigers. However, status of the big cat remains precarious. Rigorous monitoring of surviving wild tiger populations continues to be essential for both understanding and recovering wild tigers. However, many tiger monitoring programs lack the necessary rigor to generate the reliable results. While the deployment of technologies, analyses, computing power and human-resource investments in tiger monitoring have greatly progressed in the last couple of decades, a full comprehension of their correct deployment has not kept pace in practice. In this volume, Dr. Ullas Karanth and Dr. James Nichols, world leaders in tiger biology and quantitative ecology, respectively, address this key challenge. The have collaborated with an extraordinary array of 30 scientists with expertise in a range of necessary disciplines - biology and ecology of tigers, prey and habitats; advanced statistical theory and practice; computation and programming; practical field-sampling methods that employ technologies as varied as camera traps, genetic analyses and geographic information systems. The book is a 'tour de force' of cutting-edge methodologies for assessing not just tigers but also other predators and their prey. The 14 chapters here are lucidly presented in a coherent sequence to provide tiger-specific answers to fundamental questions in animal population assessment: why monitor, what to monitor and how to monitor. While highlighting robust methods, the authors also clearly point out those that are in use, but unreliable. The managerial dimension of tiger conservation described here, the task of matching monitoring objectives with skills and resources to integrate tiger conservation under an adaptive framework, also renders this volume useful to wildlife scientists as well as conservationists.

Download or read book Spatial Dynamics and Ecology of Large Ungulate Populations in Tropical Forests of India written by N. Samba Kumar and published by Springer Nature. This book was released on 2020-11-02 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology – spatially explicit line transect sampling – based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.

Download or read book Among Tigers written by K. Ullas Karanth and published by Chicago Review Press. This book was released on 2022-11-01 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today ten times more tigers live in captivity than survive in the wild. For over five decades, K. Ullas Karanth has been engaged in the struggle to bring wild tigers back from the brink in India, their last remaining wild stronghold. He tells the story of the tiger itself—its incredible biology, its critical role in shaping natural ecosystems of Asia, and the unique place it holds in our collective imagination. Among Tigers is the story of how we wound up with fewer than 5,000 wild tigers, and how, with focused efforts we can grow that population ten times or more in a few decades. In doing so, we would bring not only the world's largest and most beloved feline back from the brink, but also save countless other species that share the tigers habitats from the freezing forests of Siberia to the tropics of India. Karanth shares the adventurous real-life story of his quest to save a species and, along the way, the hopeful realization that tiger conservation is a battle that can be won. Ultimately, the book is a roadmap showing us how to not only to save the greatest of great cats, but to bring it roaring back at numbers never before seen in our lifetimes.
Download or read book Tigers of the World written by Ronald Tilson and published by Academic Press. This book was released on 2009-11-30 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tigers of the World, Second Edition explores tiger biology, ecology, conservation, management, and the science and technology that make this possible. In 1988, when the first edition was published, tiger conservation was still in its infancy, and two decades later there has been a revolution not only in what is known, but how information about tigers is obtained and disseminated. In the fast changing world of conservation, there is a great need to summarize the vast and current state-of-the-art, to put this into historical perspective, and to speculate in what yet remains to be done. Tigers of the World, Second Edition fulfills this need by bringing together in a unique way the world’s leading tiger experts into one volume. Despite the challenges ahead, there are bright spots in this story and lessons aplenty not only for tiger specialists but large carnivore specialists, conservation biologists, wildlife managers, natural resource policymakers, and most importantly the caring public. Examines the past twenty years of research from the world’s leading tiger experts on biology, politics, and conservation Describes latest methods used to disseminate and obtain information needed for conservation and care of this species Includes coverage on genetics and ecology, policy, poaching and trade, captive breeding and farming, and the status of Asia’s last wild tigers Excellent resource for grad courses in conservation biology, wildlife management, and veterinary programs New volume continues the classic Noyes Series in Animal Behavior, Ecology, Conservation and Management
Download or read book Science based conservation of tigers Assessing the past to prepare for the future written by Carlos Ruiz-Miranda and published by Frontiers Media SA. This book was released on 2024-06-13 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Research Topic, we plan to assess the interface of conservation and science, looking at the various aspects of tiger conservation by assessing what advances have been made in each relevant field, where are the limitations, and what does the data show us about successes and failures in conserving tigers, their prey and their habitat. Through a series of multiple-authored papers, we plan to explore the realms of tiger and prey monitoring, law enforcement, habitat restoration efforts, human-tiger conflicts, landscape connectivity and ultimately how tiger conservation strategies have evolved and emerged leading up to the present. Coming at this critical time – with 2022 being the Year of the Tiger and the end of a 12-year pledge by Tiger Range Countries to double tiger numbers - this Research Topic will provide a landmark publication reflecting back on the past 12 (and more) years of tiger conservation and research, and laying the foundation for the coming twelve years. While the focus is on tigers, the studies will have wide application to efforts to conserve other large-bodied carnivores. In 2010, the lunar year of the tiger, a “Tiger Summit” was held in the Russian city of St. Petersburg, where 13 Tiger Range Countries pledged to double tiger numbers by the next lunar year of the tiger in 2022. The science of tiger conservation has developed in multiple ways over the past twelve years. As we approach this benchmark, when tiger range countries will be reporting on their past efforts and planning for the next twelve years, it is important to assess what has been accomplished, and what yet needs to be done; where there have been successes, and what has not worked. This is why it is particularly important to employ a science-based approach to conservation, something that is not universally adopted by tiger conservation advocates, but which we, as editors of this collection consider central to successful tiger conservation. This Research Topic will lay the foundation for effective science-based conservation of tigers for the next twelve years. In 2021 a collection of representatives from the international tiger conservation community developed a “joint NGO vision” of priorities in tiger conservation for the coming twelve years. In this Research Topic we plan to focus on the critical issues for global tiger conservation as identified by this international group. This topic will discuss these issues and highlight how they have been addressed in diverse tiger landscapes, including both successes and failures. Our goal is to provide a foundation and structure for site-based tiger conservation actions within, and beyond, the next 12-year lunar cycle. This Research Topic was conceptualized and launched by Dale Miquelle, Thomas Gray, Luke Hunter, Abishek Harihar, John Goodrich and Matthew Linkie, in collaboration with Frontiers, to focus on: • The Convergence of Site-based tiger conservation strategies • Opportunities for restoration of tigers across their historical range • Recovery of tigers in Thailand’s tiger conservation landscapes (what works). • An integrated law enforcement approach for protecting tigers and their prey in Sumatra. • Cost of ranger protection for tiger protected area. • Evaluating a site-based enforcement strategy, Malaysia. • Beyond density: better indicators for tiger monitoring. • Prey Recovery is the foundation of tiger restoration. • Resolving human-tiger conflicts. • Community-based tiger conservation: Can it work? • Ensuring connectivity of tiger conservation landscapes. • Emerging infectious disease threats. • Tiger conservation and global/regional initiatives.

Download or read book Estimating Presence and Abundance of Closed Populations written by George A. F. Seber and published by Springer Nature. This book was released on 2024-01-02 with total page 734 pages. 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.
