No differences in microbial community composition or sponge health were detected in treatments between 27 and 31 °C. Once the temperature increased up to 33 °C, sponges underwent a complete decline of the symbionts which led to cellular ...

This book focuses on the symbiotic microbiomes of invertebrates in coral reefs, especially sponges and corals. It provides in-depth and up-to-date reviews on the microbial structure and diversity, metabolism and function, symbiosis and coevolution, environment and adaption, and bioactive potentials. Meanwhile, the future perspectives will be discussed according to the existing problems and the development trend. This book will be of particular interest to the professionals in marine ecology, marine biotechnology, as well as medicinal chemists and molecular biologists.
Clearly , the importance of symbiosis and dialectical concepts cannot be understated in the context of the structure of evolution . Later in the study , further references will be made to symbiosis in design and planning ; for now one ...
Now that the symbiotic community within the termite gut has been shown to be highly structured, many aspects of the interactions between the host and the symbionts and among the symbionts should be studied further.

Symbiosis is the fourth volume in the series Cellular Origin and Life in Extreme Habitats (COLE). Fifty experts, from over a dozen countries, review their current studies on different approaches to these phenomena. The chapters present various aspects of symbiosis from gene transfer, morphological features, and biodiversity to individual organisms sharing mutual cellular habitats. The origin of the eukaryotic phase is discussed with emphasis on cyanelles, H syntrophy, N2 fixation, and S-based symbiosis (as well as the origin of mitochondrion, chloroplast, and nucleus). All members of the three domains of life are presented for sharing symbiotic associations. This volume brings the concept of living together as `One plus One (plus One) equals One.' The purpose of this book is to introduce the teacher, researcher, scholar, and student as well as the open-minded and science-oriented reader to the global importance of this association.

Symbiosis is an intimate relationship between different living entities and is widespread in virtually all organisms. It was critical for the origin and diversification of Eukaryotes and represents a major driving force in evolution. Indeed, symbiosis may support a wide range of biological processes, including those underlying the physiology, development, reproduction, health, behavior, ecology and evolution of the organisms involved in the relationship. Although often confused with mutualism, when both organisms benefit from the association, symbiosis actually encompasses several and variable relationships. Among them is parasitism, when one organism benefits but the other is harmed, and commensalism, when one organism benefits and the other remains unaffected. Even if many symbiotic lifestyles do exist in nature, in many cases the intimacy between the partners is so deep that the “symbiont” (sensu strictu) resides into the tissues and/or cells of the other partner. Since the partners frequently belong to different kingdoms, e.g. bacteria, fungi, protists and viruses living in association with animal and plant hosts, their shared “language” should be a basic and ancient form of communication able to effectively blur the boundaries between extremely different living entities. In recent years studies on the role of epigenetics in shaping host-symbiont interactions have been flourishing. Epigenetic changes include, but are not limited to, DNA methylation, remodelling of chromatin structure through histone chemical modifications and RNA interference. In this E-book we present a series of papers exploring the fascinating developmental and evolutionary relationship between symbionts and hosts, by focusing on the mediating epigenetic processes that enable the communication to be effective and robust at both the individual, the ecological and the evolutionary time scales. In particular, the papers consider the role of epigenetic factors and mechanisms in the interactions among different species, comprising the holobiont and host-parasite relationships. On the whole, since epigenetics is fast-acting and reversible, enabling dynamic developmental communication between hosts and symbionts at several different time scale, we argue that it could account for the enormous plasticity that characterizes the interactions between all the organisms living symbiotically on our planet.

Throughout the natural world, organisms have responded to predators, inadequate resources, or inclement conditions by forming ongoing mutually beneficial partnerships--or symbioses--with different species. Symbiosis is the foundation for major evolutionary events, such as the emergence of eukaryotes and plant eating among vertebrates, and is also a crucial factor in shaping many ecological communities. The Symbiotic Habit provides an accessible and authoritative introduction to symbiosis, describing how symbioses are established, function, and persist in evolutionary and ecological time. Angela Douglas explains the evolutionary origins and development of symbiosis, and illustrates the principles of symbiosis using a variety of examples of symbiotic relationships as well as nonsymbiotic ones, such as parasitic or fleeting mutualistic associations. Although the reciprocal exchange of benefit is the key feature of symbioses, the benefits are often costly to provide, causing conflict among the partners. Douglas shows how these conflicts can be managed by a single controlling organism that may selectively reward cooperative partners, control partner transmission, and employ recognition mechanisms that discriminate between beneficial and potentially harmful or ineffective partners. The Symbiotic Habit reveals the broad uniformity of symbiotic process across many different symbioses among organisms with diverse evolutionary histories, and demonstrates how symbioses can be used to manage ecosystems, enhance food production, and promote human health.
In this case, stressors may affect not only the host but also its symbiotic community (i.e., parasites, commensals, or mutualists), and the relationship between partners. A canonical example is the negative impact of global warming on ...

The book deals in detail with previously understudied language contact settings in the Balkans (South East Europe) that present a continuum between ethnic and linguistic separation and symbiosis among groups of people. The studies in this volume achieve several aims: they critically assess the Balkan Sprachbund theory; they analyse general contact theories against the background of new, original, representative field and historical Greek, Albanian, Romance, Slavic and Judesmo data; they employ and contribute to recent methods of research on linguistic convergence in bilingual societies; they propose new general assessments of extra- and intralinguistic factors of Balkanization over the centuries; and they outline prospects for future research. The factors relevant to contact scenarios and linguistic change in the Balkans are identified and typologized through models such as those related to a balanced or unbalanced (socio)linguistic situation.
