The field of amphibian microbial ecology has greatly advanced in recent years. The work published to date has shown that amphibian skin bacterial communities can be influenced by host species, host life-history stage, environmental conditions, surrounding bacterial communities that serve as reservoirs and external biotic agents such as pathogens. As the ecology of amphibian-microbial symbiosis is a relatively new field, there are still many unanswered questions. The aim of this Research Topic is to highlight recent research on amphibian microbiomes that addresses relevant questions on the ecology of amphibian-microbe interactions. The publications gathered in this Research Topic have expanded our knowledge on the role of microbial symbionts of amphibians and have revealed novel insights that can direct the next set of research questions. We suggest that soon the field will move from the basic (and necessary) descriptions of microbial communities to more experimental approaches that include the use of omics methods and a variety of novel analytic and multivariate approaches. In addition to providing more insights into the microbial and disease ecology of amphibians, these studies may lead to effective ways to manipulate the microbiome to achieve protection from diseases, such as chytridiomycosis.

The role of parasites and pathogens in the evolution of life history traits is of increasing interest to both ecologists and evolutionary biologists. Immunology, which was once studied almost exclusively by immunologists, has become an important area of proximate investigation to animal physiologists as a means for understanding changes in disease susceptibility and the neural and neuroendocrine mechanisms that mediate these changes. The coalescence of these different perspectives has given rise to the field of ecological immunology, an interdisciplinary research field that examines interactions among host physiology and disease ecology in a wide range of environmentally relevant contexts. The goal of ecological immunology is to understand immune function in the context of life-history traits across a wide range of organisms. Research within the field combines diverse approaches from a wide range of scientific disciplines including evolution, ecology, and life history theory to endocrinology, neuroscience, molecular biology, and behavior. This book critically reviews recent advances in the discipline of ecoimmunology. Chapters are written by experts in their respective fields and cover diverse topics including how environmental factors can affect host immune function, the complex dynamics among host immunity, pathogen prevalence and disease susceptibility, and the physiological mechanisms that lead to adaptive changes in immune responses. By integrating analyses of immune system function within animal biology, investigators will gain will gain a more comprehensive and satisfying understanding of organism-environment interactions at both ultimate and proximate levels of analysis.

This book covers the ecological activities of microbes in the biosphere with an emphasis on microbial interactions within their environments and communities In thirteen concise and timely chapters, Microbial Ecology presents a broad overview of this rapidly growing field, explaining the basic principles in an easy-to-follow manner. Using an integrative approach, it comprehensively covers traditional issues in ecology as well as cutting-edge content at the intersection of ecology, microbiology, environmental science and engineering, and molecular biology. Examining the microbial characteristics that enable microbes to grow in different environments, the book provides insights into relevant methodologies for characterization of microorganisms in the environment. The authors draw upon their extensive experience in teaching microbiology to address the latest hot-button topics in the field, such as: Ecology of microorganisms in natural and engineered environments Advances in molecular-based understanding of microbial phylogeny and interactions Microbially driven biogeochemical processes and interactions among microbial populations and communities Microbial activities in extreme or unusual environments Ecological studies pertaining to animal, plant, and insect microbiology Microbial processes and interactions associated with environmental pollution Designed for use in teaching, Microbial Ecology offers numerous special features to aid both students and instructors, including: Information boxes that highlight key microbial ecology issues "Microbial Spotlights" that focus on how prominent microbial ecologists became interested in microbial ecology Examples that illustrate the role of bacterial interaction with humans Exercises to promote critical thinking Selected reading lists Chapter summaries and review questions for class discussion Various microbial interactions and community structures are presented through examples and illustrations. Also included are mini case studies that address activities of microorganisms in specific environments, as well as a glossary and key words. All these features make this an ideal textbook for graduate or upper-level undergraduate students in biology, microbiology, ecology, or environmental science. It also serves as a highly useful reference for scientists and environmental professionals.

Growing demographic trends require sustainable technologies to improve quality and yield of future food productions. However, there is uncertainty about plant protection strategies in many agro-ecosystems. Pests, diseases, and weeds are overwhelmingly controlled by chemicals which pose health risks and cause other undesirable effects.Therefore, an increasing concern on control measures emerged in recent years. Many chemicals became questioned with regard to their sustainability and are (or will be) banned. Alternative management tools are studied, relying on biological, and low impact solutions. This ResearchTopic concerns microbial biocontrol agents, root-associated microbiomes, and rhizosphere networks. Understanding how they interact or respond to (a)biotic environmental cues is instrumental for an effective and sustainable impact. The rhizosphere is in this regard a fundamental object of study, because of its role in plant productivity. This e-book provides a polyhedral perspective on many issues in which beneficial microorganisms are involved. Data indeed demonstrate that they represent an as yet poorly-explored resource, whose exploitation may actively sustain plant protection and crop production. Given the huge number of microbial species present on the planet, the microorganisms studied represent just the tip of an iceberg. Data produced are, however, informative enough about their genetic and functional biodiversity, as well as about the ecosystem services they provide to underp in crop production. Challenges for future research work concern not only the biology of these species, but also the practices required to protect their biodiversity and to extend their application in the wide range of agricultural soils and systems present in the world. Agriculture cannot remain successfully and sustainable unless plant germplasm and useful microbial species are integrated, a goal for which new knowledge and information-based approaches are urgently needed.

Though physiological ecology has been a discipline since the 1950s, McNab redresses a perceived absence of a theoretical framework with a comparative, inductive approach to studying vertebrate evolution and ecology. He discusses the patterns and limits of adaptation to the environment, acclimation to temperature variation and material exchange with the environment, and the energetics of locomotion and growth. The final section treats the significance of energetics for population ecology and distribution. Includes a taxonomic as well as subject index. Suitable for advanced students and researchers in the biological and ecological sciences. The Gainesville, FL-based author is referred to by the foreword writer as a keen naturalist, but his credentials are not stated. Annotation copyrighted by Book News Inc., Portland, OR.
