Download or read book Activity Patterns in Small Mammals written by S. Halle and published by Springer. This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.

Download or read book Camera Traps in Animal Ecology written by Allan F. O'Connell and published by Springer Science & Business Media. This book was released on 2010-10-05 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote photography and infrared sensors are widely used in the sampling of wildlife populations worldwide, especially for cryptic or elusive species. Guiding the practitioner through the entire process of using camera traps, this book is the first to compile state-of-the-art sampling techniques for the purpose of conducting high-quality science or effective management. Chapters on the evaluation of equipment, field sampling designs, and data analysis methods provide a coherent framework for making inferences about the abundance, species richness, and occupancy of sampled animals. The volume introduces new models that will revolutionize use of camera data to estimate population density, such as the newly developed spatial capture–recapture models. It also includes richly detailed case studies of camera trap work on some of the world’s most charismatic, elusive, and endangered wildlife species. Indispensible to wildlife conservationists, ecologists, biologists, and conservation agencies around the world, the text provides a thorough review of the subject as well as a forecast for the use of remote photography in natural resource conservation over the next few decades.
Download or read book The Biological Clock written by Frank A. Brown and published by Academic Press. This book was released on 2014-06-28 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biological Clock describes the rhythmic processes in a great variety of plants and animals. This book is an outgrowth of the 1969 James Arthur Lecture Series on "Time and its Mysteries" held at New York University. This three-chapter work begins with the basic principles of biological rhythms and clocks, along with various diagrams to illustrate some aspects of circadian rhythms in animals. The second chapter discusses the hypothesis of environmental timing of the clock. This chapter explores numerous research studies on phenomenon of biological rhythms, the nature of the rhythmic mechanism, and hormonal regulation. The third chapter examines the cellular-biochemical clock hypothesis and its contribution in the progress of understanding the complexity of biological rhythm. This book is intended primarily for biologists, behaviorists, and researchers.

Download or read book Phyllostomid Bats written by Theodore H Fleming and published by University of Chicago Press. This book was released on 2020-10-05 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than two hundred species distributed from California through Texas and across most of mainland Mexico, Central and South America, and islands in the Caribbean Sea, the Phyllostomidae bat family (American leaf-nosed bats) is one of the world’s most diverse mammalian families. From an insectivorous ancestor, species living today, over about 30 million years, have evolved a hyper-diverse range of diets, from blood or small vertebrates, to consuming nectar, pollen, and fruit. Phyllostomid plant-visiting species are responsible for pollinating more than five hundred species of neotropical shrubs, trees, vines, and epiphytes—many of which are economically and ecologically important—and they also disperse the seeds of at least another five hundred plant species. Fruit-eating and seed-dispersing members of this family thus play a crucial role in the regeneration of neotropical forests, and the fruit eaters are among the most abundant mammals in these habitats. Coauthored by leading experts in the field and synthesizing the latest advances in molecular biology and ecological methods, Phyllostomid Bats is the first overview in more than forty years of the evolution of the many morphological, behavioral, physiological, and ecological adaptations in this family. Featuring abundant illustrations as well as details on the current conservation status of phyllostomid species, it is both a comprehensive reference for these ecologically vital creatures and a fascinating exploration of the evolutionary process of adaptive radiation.

Download or read book Noninvasive Survey Methods for Carnivores written by Robert A. Long and published by Island Press. This book was released on 2012-09-26 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of many carnivore populations is of growing concern to scientists and conservationists, making the need for data pertaining to carnivore distribution, abundance, and habitat use ever more pressing. Recent developments in “noninvasive” research techniques—those that minimize disturbance to the animal being studied—have resulted in a greatly expanded toolbox for the wildlife practitioner. Presented in a straightforward and readable style, Noninvasive Survey Methods for Carnivores is a comprehensive guide for wildlife researchers who seek to conduct carnivore surveys using the most up-to-date scientific approaches. Twenty-five experts from throughout North America discuss strategies for implementing surveys across a broad range of habitats, providing input on survey design, sample collection, DNA and endocrine analyses, and data analysis. Photographs from the field, line drawings, and detailed case studies further illustrate on-the-ground application of the survey methods discussed. Coupled with cutting-edge laboratory and statistical techniques, which are also described in the book, noninvasive survey methods are effi cient and effective tools for sampling carnivore populations. Noninvasive Survey Methods for Carnivores allows practitioners to carefully evaluate a diversity of detection methods and to develop protocols specific to their survey objectives, study area, and species of interest. It is an essential resource for anyone interested in the study of carnivores, from scientists engaged in primary research to agencies or organizations requiring carnivore detection data to develop management or conservation plans.
Download or read book The Circadian Clock written by Urs Albrecht and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

Download or read book Animal Dispersal written by N.C. Stenseth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.
Download or read book Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2003-08-22 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding on the National Research Council's Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of these animals, and guidance on adapting these guidelines to various situations without hindering the research process. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research offers a more in-depth treatment of concerns specific to these disciplines than any previous guide on animal care and use. It treats on such important subjects as: The important role that the researcher and veterinarian play in developing animal protocols. Methods for assessing and ensuring an animal's well-being. General animal-care elements as they apply to neuroscience and behavioral research, and common animal welfare challenges this research can pose. The use of professional judgment and careful interpretation of regulations and guidelines to develop performance standards ensuring animal well-being and high-quality research. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research treats the development and evaluation of animal-use protocols as a decision-making process, not just a decision. To this end, it presents the most current, in-depth information about the best practices for animal care and use, as they pertain to the intricacies of neuroscience and behavioral research.
Download or read book Measuring and Monitoring Biological Diversity written by Ronald Heyer and published by Smithsonian Institution. This book was released on 2014-12-16 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring and Monitoring Biological Diversity is the first book to provide comprehensive coverage of standard methods for biodiversity sampling of amphibians, with information on analyzing and using data that will interest biologists in general. In this manual, nearly fifty herpetologists recommend ten standard sampling procedures for measuring and monitoring amphibian and many other populations. The contributors discuss each procedure, along with the circumstances for its appropriate use. In addition, they provide a detailed protocol for each procedure's implementation, a list of necessary equipment and personnel, and suggestions for analyzing the data. The data obtained using these standard methods are comparable across sites and through time and, as a result, are extremely useful for making decisions about habitat protection, sustained use, and restoration—decisions that are particularly relevant for threatened amphibian populations.

Download or read book Wildlife 2001 Populations written by D.R. McCullough and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.
