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.

Das erste Lehrbuch zur Ökologie der Wirbeltiere Der Wolf frisst einen Elch, der Luchs ein Reh und der Habicht einen jungen Waldkauz. Was bedeutet das für die Bestände der Beutetiere? Vögel und Säugetiere zeigen als endotherme Wirbeltiere viele Gemeinsamkeiten in ihrer Biologie. Ausgehend von den theoretischen Grundlagen der Ökologie und mit einem konsequent evolutionsbiologischen Ansatz behandelt «Ökologie der Wirbeltiere» die Ernährung unter ökophysiologischen und verhaltensökologischen Aspekten, die Fortpflanzung, die räumliche Ökologie auf allen Skalenebenen, Wanderungen, die Populationsbiologie sowie die Interaktionen zwischen Arten, nämlich Konkurrenz, Prädation und Parasiten, und schließt mit einem Kapitel zur Naturschutzbiologie. Die theoretischen Grundlagen sind stets mit den aktuellen empirischen Befunden verknüpft; diesen wird ein großes Gewicht beigemessen. Dieser Titel ist auf verschiedenen e-Book-Plattformen (Amazon, Apple, Libri, Thalia) auch als e-Pub-Version für mobile Lesegeräte verfügbar.

Understanding wildlife population ecology is vital for all wildlife managers and conservation biologists. Leopold draws on 30 years of research and teaching experience to give students and natural resource professionals the foundation they need to effectively manage wildlife populations. He begins with the key statistical concepts and research approaches necessary to gain insight into various models of population dynamics. The many factors that influence wildlife populations are thoroughly explored and their consequences are investigated. In addition, the author presents techniques for analyzing wildlife harvest data and a lucid discussion of valuable wildlife census methods. Frequent examples of foundational literature supplement each chapter with applications of the theories and provide a concise compendium of fundamental concepts of population ecology. Abundant statistical exercises reinforce students’ learning throughout the text.

This book is intended for use by natural resource managers andscientists, and students in the fields of natural resourcemanagement, ecology, and conservation biology, who are confrontedwith complex and difficult decision making problems. The book takesreaders through the process of developing a structured approach todecision making, by firstly deconstructing decisions into componentparts, which are each fully analyzed and then reassembled to form aworking decision model. The book integrates common-senseideas about problem definitions, such as the need for decisions tobe driven by explicit objectives, with sophisticated approaches formodeling decision influence and incorporating feedback frommonitoring programs into decision making via adaptive management.Numerous worked examples are provided for illustration, along withdetailed case studies illustrating the authors’ experience inapplying structured approaches. There is also a series of detailedtechnical appendices. An accompanying website providescomputer code and data used in the worked examples.

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.

Wildlife professionals can more effectively manage species and social-ecological systems by fully considering the role that humans play in every stage of the process. Human Dimensions of Wildlife Management provides the essential information that students and practitioners need to be effective problem solvers. Edited by three leading experts in wildlife management, this textbook explores the interface of humans with wildlife and their sometimes complementary, often conflicting, interests. The book's well-researched chapters address conservation, wildlife use (hunting and fishing), and the psychological and philosophical underpinnings of wildlife management. Human Dimensions of Wildlife Management explains how a wildlife professional should handle a variety of situations, such as managing deer populations in residential areas or encounters between predators and people or pets. This thoroughly revised and updated edition includes detailed information about • systems thinking• working with social scientists• managing citizen input• using economics to inform decision making• preparing questionnaires• ethical considerations

Abstract: Mexico is considered a country of biological megadiversity because of its exceptional species richness and endemism. However, much of Mexico's biodiversity is under threat due to a variety of factors, in particular, habitat loss. The Mexican legal standard (Norma Oficial Mexicana; NOM-ECOL-059-2010) uses four criteria to analyze specieś extinction risk at a national scale. However, when prioritizing areas for biodiversity conservation it is also important to incorporate knowledge of the conservation status of species at a more localized scale (regional, state, or municipal levels) for identifying possible risks associated with population declines. This paper focuses on Guerrero, which is the fourth most biologically diverse state in Mexico. The total extent of the conservation areas in Guerrero is low, amounting to 0.09% of its total area. We analyzed data for 582 terrestrial vertebrate species in Guerrero (53 amphibians, 115 reptiles, 334 birds and 80 mammals), modeling their potential distribution using a maximum entropy algorithm, and 114, 555 occurrence records, and 23 predictive environmental (19 climatic and four topographical) variables. The portion of the potential distribution for each species including only remnant natural habitat was designated as its predicted distribution. The area of the predicted distribution was used to compute the fraction of natural habitat remaining for each species overlapping within decreed protected areas at the state and national levels, that is, for Guerrero and all of Mexico. Results show significant differences in the fraction of species' predicted distribution and species' potential distribution at different scales (state and national) and differences between the vertebrate groups analyzed. Because quantitative conservation targets are typically set for individual species, this exercise enables an analysis of the impact of the habitat lost on each species' distribution by assessing the fraction of its predicted distribution that coincides with protected areas. We conclude that this must be part of systematic conservation planning to prioritize areas for potential conservation in Guerrero.

This book demonstrates that trade-offs can be very important for conservationists. Its various chapters show how and why trade-offs are made, and why conservationists need to think very hard about what, if anything, to do about them. The book argues that conservationists must carefully weigh up, and be explicit about, the trade-offs that they make every day in deciding what to save. Key Features: Discusses the wider non-biological issues that surround making decisions about which species and biogeographic areas to prioritise for conservation Focuses on questions such as: What are these wider issues that are influencing the decisions we make? What factors need to be included in our assessment of trade-offs? What package of information and issues do managers need to consider in making a rational decision? Who should make such decisions? Part of the Conservation Science and Practice book series This volume is of interest to policy-makers, researchers, practitioners and postgraduate students who are concerned about making decisions that include recognition of trade-offs in conservation planning.
