Book Description
Plants and animals have evolved ever since their appearance in a largely microbial world. Their own cells are less numerous than the microorganisms that they host and with whom they interact closely. The study of these interactions, termed microbial symbioses, has benefited from the development of new conceptual and technical tools. We are gaining an increasing understanding of the functioning, evolution and central importance of symbiosis in the biosphere. Since the origin of eukaryotic cells, microscopic organisms of our planet have integrated our very existence into their ways of life. The interaction between host and symbiont brings into question the notion of the individual and the traditional representation of the evolution of species, and the manipulation of symbioses facilitates fascinating new perspectives in biotechnology and health. Recent discoveries show that association is one of the main properties of organisms, making a more integrated view of biology necessary. Microbial Symbioses provides a deliberately "symbiocentric outlook, to exhibit how the exploration of microbial symbioses enriches our understanding of life, and the potential future for this discipline. - Offers a concise summary of the most recent discoveries in the field - Shows how symbiosis is acquiring a central role in the biology of the 21st century by transforming our understanding of living things - Presents scientific issues, but also societal and economic related issues (biodiversity, biotechnology) through examples from all branches of the tree of life

Book Description
Welcome to the wonderful world of microbiology! Yay! So. What is microbiology? If we break the word down it translates to "the study of small life," where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they? Generally microbes can be divided in to two categories: the cellular microbes (or organisms) and the acellular microbes (or agents). In the cellular camp we have the bacteria, the archaea, the fungi, and the protists (a bit of a grab bag composed of algae, protozoa, slime molds, and water molds). Cellular microbes can be either unicellular, where one cell is the entire organism, or multicellular, where hundreds, thousands or even billions of cells can make up the entire organism. In the acellular camp we have the viruses and other infectious agents, such as prions and viroids. In this textbook the focus will be on the bacteria and archaea (traditionally known as the "prokaryotes,") and the viruses and other acellular agents.

Book Description
This volume summarizes recent advances in our understanding of the mechanisms that produce successful symbiotic partnerships involving microorganisms. It begins with a basic introduction to the nature of and mechanistic benefits derived from symbiotic associations. Taking that background knowledge as the starting point, the next sections include chapters that examine representative examples of coevolutionary associations that have developed between species of microbes, as well as associations between microbes and plants. The authors conclude with a section covering a broad range of associations between microbes and invertebrate animals, in which they discuss the spectrum of hosts, with examples ranging from bryozoans and corals to nematodes, arthropods, and cephalopods.

Book Description
Insects engage in intimate associations with microbial symbionts that colonize their digestive systems or internal cells and tissues. The stability and near ubiquity of many of these "symbioses" implies their importance, a prediction supported through experimentation. With the advancing power of experimental methodologies and the growing accessibility of genomic techniques, insect science has reached a powerful new stage enabling the study of previously recalcitrant symbioses, including several with medical and agricultural significance. In this volume we publish a collection of chapters focused on the physiology of insect-microbe symbioses, emphasizing their mechanistic underpinnings, and the ecological and evolutionary causes and consequences of these interactions. Resident microbes modulate insect digestion, nutrition, detoxification, reproduction, interspecies signaling, and host-parasite interactions, and these chapters synthesize impactful, state-of-the art research on insect-microbe symbioses. Through discussions of the mechanisms that both stabilize and regulate these symbioses, these chapters yield further insight into the physiological integration between many insects and their influential microbial partners.

Anemones and fish, ants and acacia trees, fungus and trees, buffaloes and oxpeckers--each of these unlikely duos is an inimitable partnership in which the species' coexistence is mutually beneficial. More specifically, they represent examples of defensive mutualism, when one species receives protection against predators or parasites in exchange for

Book Description
These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty.A departure from mainstream biology, the idea of symbiosis--as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals--has attracted the attention of a growing number of scientists.These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal-bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. ContributorsPeter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.

Book Description
One of the central questions of ecology is why there are so many different kinds of plants and animals. Here David Tilman presents a theory of how organisms compete for resources and the way their competition promotes diversity. Developing Hutchinson's suggestion that the main cause of diversity is the feeding relations of species, this book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities. In a detailed analysis of the Park Grass Experiments at the Rothamsted Experimental Station in England, the author demonstrates that the dramatic results of these 120 years of experimentation are consistent with his theory, as are observations in many other natural communities. The consumer-resource approach of this book is applicable to both animal and plant communities, but the majority of Professor Tilman's discussion concentrates on the structure of plant communities. All theoretical arguments are developed graphically, and formal mathematics is kept to a minimum. The final chapters of the book provide some testable speculations about resources and animal communities and explore such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.

Book Description
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.
