This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis investigates the relationship between host diversity and Lyme disease. There are two main hypotheses linking host diversity to Lyme disease incidence; the first, the "dilution effect" hypothesis predicts a negative relationship, while the second, the "amplification effect" hypothesis predicts a positive relationship. Research to date suggests that the diversity-Lyme disease relationship is more nuanced than either of these hypotheses, such that the observed relationship may be dependent upon the particular temporal or spatial scale of observation, among other factors. In my first chapter, I review previous theory, models, and empirical evidence relating to the host diversity-Lyme disease relationship. Chapter 2 is a statistical investigation, using generalized linear mixed models, of the relationship between tick host species richness and Lyme disease incidence in the United States from 1992 to 2011. We found an increasingly negative relationship between host diversity and disease incidence in time, indicating an increasing dilution effect. Chapter 3 is a statistical analysis, again using a generalized linear mixed model, of the relationship between small mammal diversity and the density of Borrelia burgdorferi infection, the pathogen responsible for Lyme disease in 27 forest sites in Southern Quebec in 2011, 2012, and 2013. We found a positive relationship between small mammal diversity and the density of Borrelia burgdorferi, indicating an amplification effect. We then explored the mechanisms driving this diversity-disease relationship in Southern Quebec using structural equation models. The contrasting findings of these two studies, which take place at different spatial and temporal scales, as well as at different degrees of Lyme disease emergence, reinforce previous findings that the diversity-Lyme disease relationship is highly context-dependent." --

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 Biodiversity Hotspots written by Frank E. Zachos and published by Springer Science & Business Media. This book was released on 2011-09-15 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity and its conservation are among the main global topics in science and politics and perhaps the major challenge for the present and coming generations. This book written by international experts from different disciplines comprises general chapters on diversity and its measurement, human impacts on biodiversity hotspots on a global scale, human diversity itself and various geographic regions exhibiting high levels of diversity. The areas covered range from genetics and taxonomy to evolutionary biology, biogeography and the social sciences. In addition to the classic hotspots in the tropics, the book also highlights various other ecosystems harbouring unique species communities including coral reefs and the Southern Ocean. The approach taken considers, but is not limited to, the original hotspot definition sensu stricto and presents a chapter introducing the 35th hotspot, the forests of East Australia. While, due to a bias in data availability, the majority of contributions on particular taxa deal with vertebrates and plants, some also deal with the less-studied invertebrates. This book will be essential reading for anyone involved with biodiversity, particularly researchers and practitioners in the fields of conservation biology, ecology and evolution.
Download or read book Measuring Plant Diversity written by Thomas J. Stohlgren and published by OUP USA. This book was released on 2007 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is a thorough presentation and critique of the sampling approaches, designs and field techniques for measuring plant diversity. Ecologists interested in assessing landscapes and ecosystems must measure biomass, cover, and the density or frequency of various key species. Recently, sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have become finer-grained, as it has become increasingly important to accurately map and assess rare species for conservation. This book lays out the range of current methods for mapping and measuring species diversity, for field ecologists, resource managers, conservation biologists, and students, as a tool kit for future field measurements of plant diversity.
Download or read book Biology and Conservation of Martens Sables and Fishers written by Keith B. Aubry and published by Cornell University Press. This book was released on 2012-11-15 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammals in the genus Martes are mid-sized carnivores of great importance to forest ecosystems. This book, the successor to Martens, Sables, and Fishers: Biology and Conservation, provides a scientific basis for management and conservation efforts designed to maintain or enhance the populations and habitats of Martes species throughout the world. The twenty synthesis chapters contained in this book bring together the perspectives and expertise of sixty-three scientists from twelve countries, and are organized by the five key themes of evolution and biogeography, population biology and management, habitat ecology and management, research techniques, and conservation. Recent developments in research technologies such as modeling and genetics, biological knowledge about pathogens and parasites, and concerns about the potential effects of global warming on the distribution and status of Martes populations make new syntheses of these areas especially timely. The volume provides an overview of what is known while clarifying initiatives for future research and conservation priorities, and will be of interest to mammalogists, resource managers, applied ecologists, and conservation biologists.
Download or read book Multi scale Variability of Ecosystem Functioning in European and Chinese Shelf Seas written by Xueen Chen and published by Frontiers Media SA. This book was released on 2024-08-26 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued global warming and ocean acidification are predicted with high confidence, while the direction and magnitude of changes of other atmospheric drivers (e.g. precipitation, wind) and nutrient loading are of high uncertainty and regionally dependent. Biogeochemical responses of coastal shelf seas to external drivers are often nonlinear, involving feedback that may amplify or dampen a perturbation imposed on the system. Coupled physical-biogeochemical process-based numerical models have proven useful in elucidating the mechanistic interplay and relative importance of the different factors contributing to ecosystem functioning with increasing realism. This research topic aims to understand and compare marine ecosystem functioning in Chinese and European shelf seas, based on studies that use state-of-the-art modeling and monitoring of coastal ecosystem dynamics. This topic will enable more efficient knowledge share and distribution through a comparative assessment between distinct coastal shelf systems in China and Europe to further our understanding of complicated ecosystem dynamics in response to a changing climate and increasing anthropogenic pressure. It will allow us to better understand the sensitivity of coastal shelf ecosystem functioning to physical and biogeochemical perturbations, the role of shelf seas in global carbon cycling, and the resilience of Chinese and European shelf seas to ongoing and future changes in climate and anthropogenic activities.

Book excerpt: Originally published in 2002, Mountain Biodiversity deals with the biological richness, function and change of mountain environments. The book was birthed from the first global conference on mountain biodiversity and was a contribution to the International Year of Mountains in 2002. The book examines biological diversity as essential for the integrity of mountain ecosystems and argues that this dependency is likely to increase as environmental climates and social conditions change. This book seeks to examine the biological riches of all major mountain ranges, from around the world and using existing knowledge on mountain biodiversity, examines a broad range of research in diversity, including that of plants, animals, human and bacterial diversity. The book also examines climate change and mountain biodiversity as well as land use and conservation.

Download or read book Experimental Landscape Ecology written by Yolanda F. Wiersma and published by Springer Nature. This book was released on 2022-04-07 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first guide to landscape ecologists on the art and science of doing experiments, both observational and manipulative. How do you conduct an experiment when your study subject is as big as a landscape? Issues of scale, spatial heterogeneity and limitations on replication may challenge scientists seeking to carry out robust experiments in landscape ecology. Beginning with an overview of the history and philosophy of the scientific method, and tracing the development of experimental approaches in ecology broadly, the first half of the book discusses the broader issues of what makes a good experiment. Individual chapters describe unique aspects of landscape ecology that present challenges to experimentation, with suggestions for solutions on issues of scale, and how to apply controls, randomization and adequate replication in a landscape setting. The second half of the book describes different kinds of landscape ecology experimental approaches including: large-scale manipulations experimental model landscapes mesocosms and microcosms in silico experiments novel landscapes Each chapter describes the advantages and disadvantages of each approach, and identifies the types of landscape ecology concepts and questions that a research can address. Examples from around the world, in a myriad of different environments, help to illustrate the ideas in each chapter. Together with an annotated resources section, this book aims to stimulate ideas and inspire creativity for graduate students and early career researchers who want to conduct better experiments in landscape ecology.
