This book was released on 2010-08-05 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the ‘tip of iceberg’ of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores (‘cry for help’ and ‘plant bodyguards’ concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.

Download or read book Mycorrhizal Mediation of Soil written by Nancy Collins Johnson and published by Elsevier. This book was released on 2016-11-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal Mediation of Soil: Fertility, Structure, and Carbon Storage offers a better understanding of mycorrhizal mediation that will help inform earth system models and subsequently improve the accuracy of global carbon model predictions. Mycorrhizas transport tremendous quantities of plant-derived carbon below ground and are increasingly recognized for their importance in the creation, structure, and function of soils. Different global carbon models vary widely in their predictions of the dynamics of the terrestrial carbon pool, ranging from a large sink to a large source. This edited book presents a unique synthesis of the influence of environmental change on mycorrhizas across a wide range of ecosystems, as well as a clear examination of new discoveries and challenges for the future, to inform land management practices that preserve or increase below ground carbon storage. Synthesizes the abundance of research on the influence of environmental change on mycorrhizas across a wide range of ecosystems from a variety of leading international researchers Focuses on the specific role of mycorrhizal fungi in soil processes, with an emphasis on soil development and carbon storage, including coverage of cutting-edge methods and perspectives Includes a chapter in each section on future avenues for further study

Download or read book Ecological Communities written by Takayuki Ohgushi and published by Cambridge University Press. This book was released on 2012-08-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To gain a more complete understanding of plant-based ecological community structure requires knowledge of the integration of direct and indirect effects in plant herbivore systems. Trait modification of plants as a result of herbivory is very common and widespread in terrestrial plants, and this initiates indirect interactions between organisms that utilise the same host plant. This book argues that food webs by themselves are inadequate models for understanding ecological communities, because they ignore important indirect, nontrophic links. This subject is of great importance in understanding not only community organisation but also in identifying the underlying mechanisms of maintenance of biodiversity in nature. This book will be an invaluable resource for researchers and graduate students interested in community and population ecology, evolutionary biology, biodiversity, botany and entomology.
Download or read book Insect Plant Biology written by Louis M. Schoonhoven and published by Oxford University Press. This book was released on 2005-12 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Aboveground Belowground Community Ecology written by Takayuki Ohgushi and published by Springer. This book was released on 2018-10-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers now recognize that above- and belowground communities are indirectly linked to one another, often by plant-mediated mechanisms. To date, however, there has been no single multi-authored edited volume on the subject. This book remedies that gap, and offers state-of-the art insights into basic and applied research on aboveground-belowground interactions and their functional consequences. Drawing on a diverse pool of global expertise, the authors present diverse approaches that span a range of scales and levels of complexity. The respective chapters provide in-depth information on the current state of research, and outline future prospects in the field of aboveground-belowground community ecology. In particular, the book’s goal is to expand readers’ knowledge of the evolutionary, community and ecosystem consequences of aboveground-belowground interactions, making it essential reading for all biologists, graduate students and advanced undergraduates working in this rapidly expanding field. It touches on multiple research fields including ecology, botany, zoology, entomology, microbiology and the related applied areas of biodiversity management and conservation.
Download or read book Allelopathy written by Manuel J. Reigosa and published by Springer Science & Business Media. This book was released on 2006-02-28 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many good books in the market dealing with the subject of allelopathy. When we designed the outline of this new book, we thought that it should include as many different points of view as possible, although in an integrated general scheme. Allelopathy can be viewed from different of perspectives, ranging from the molecular to the ecosystem level, and including molecular biology, plant biochemistry, plant physiology, plant ecophysiology and ecology, with information coming also from the organic chemistry, soil sciences, microbiology and many other scientific disciplines. This book was designed to include a complete perspective of allelopathic process. The book is divided into seven major sections. The first chapter explores the international development of allelopathy as a science and next section deals with methodological aspects and it explores potential limitations of actual research. Third section is devoted to physiological aspects of allelopathy. Different specialists wrote about photosynthesis, cell cycle, detoxification processes, abiotic and biotic stress, plant secondary metabolites and respiration related to allelopathy. Chapters 13 through 16 are collectively devoted to various aspects of plant ecophysiology on a variety of levels: microorganisms, soil system and weed germination. Fundamental ecology approaches using both experimental observations and theoretical analysis of allelopathy are described in chapters 16 and 17. Those chapters deal with the possible evolutionary forces that have shaped particular strategies. In the section named “allelopathy in different environments”, authors primarily center on marine, aquatic, forest and agro ecosystems. Last section includes chapters addressing application of the knowledge of allelopathy.
Download or read book Arbuscular Mycorrhizas Physiology and Function written by Hinanit Koltai and published by Springer Science & Business Media. This book was released on 2010-08-25 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years since the first edition of “Arbuscular Mycorrhizas: Physiology and Function” was published, an exceptional proliferation of interest in mycorrhizal biology has developed. This has been associated with advances in different research disciplines such as genetics, genomics, proteomics, metabolomics and physiology, advances which have generated better insight into topics of mycorrhizal biology, including the mechanisms of host-mycorrhiza interactions pre- and post-penetration, the influence of the symbiosis on the host and its surroundings, and the evolution and diversity of mycorrhization. It therefore became necessary to both update and expand the book's coverage in this, its second edition.
Download or read book Interaction and Coevolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2014-02-14 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: “It is not only the species that change evolutionarily through interactions . . . the interactions themselves also change.” Thus states John N. Thompson in the foreword to Interaction and Coevolution, the first title in his series of books exploring the relentless nature of evolution and the processes that shape the web of life. Originally published in 1982 more as an idea piece—an early attempt to synthesize then academically distinct but logically linked strands of ecological thought and to suggest avenues for further research—than as a data-driven monograph, Interaction and Coevolution would go on to be considered a landmark study that pointed to the beginning of a new discipline. Through chapters on antagonism, mutualism, and the effects of these interactions on populations, speciation, and community structure, Thompson seeks to explain not only how interactions differ in the selection pressures they exert on species, but also when interactions are most likely to lead to coevolution. In this era of climate change and swiftly transforming environments, the ideas Thompson puts forward in Interaction and Coevolution are more relevant than ever before.

Download or read book Arbuscular Mycorrhizas written by Yoram Kapulnik and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have brought an upsurge of interest in the study of arbuscular mycorrhizal (AM) fungi, partly due to the realization that the effective utilization of these symbiotic soil fungi is likely to be essential in sustainable agriculture. Impressive progress has been made during the last decade in the study of this symbiosis largely as a result of increasing exploitation of molecular tools. Although early emphasis was placed on the use of molecular tools to study physiological processes triggered by the symbiosis, such as expression of symbiosis-specific polypeptides and modulation of host defences, other applications await. It was obvious to us that gathering leaders in the field to summarize these topics and point out research needs was necessary if we were to understand the physiology and function of AM fungi at a molecular level. In addition, we have taken the opportunity to present these reviews in a logical sequence of topics ranging from the initiation of the life cycle of the fungus to its functions in plant growth and in the below ground ecosystem. It was a challenge to limit this flood of information to the confines of one text. This is a very exciting time for mycorrhiza biologists and it is our hope that some of this excitement is conveyed to our readers.

Download or read book Nematode Trapping Fungi written by Ke-Qin Zhang and published by Springer Science & Business. This book was released on 2014-04-22 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: These chapters provide up-to-date information on nematophagous fungi, particularly those of the Orbiliaceae in Ascomycota, whose asexual states produce nematode-trapping devices. The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Nematode-trapping fungi with adhesive or mechanical hyphal traps are the main focus of this book which begins with an overview of the data on nematode-trapping fungi, including their taxonomy, phylogeny and evolution. Subsequent chapters expand upon the methods and techniques used to study these fascinating fungi. Keys for genera of Arthrobotrys, Drechslerella and Dactylellina, which include all reported species of predatory orbiliaceous fungi are presented and numerous species from these genera are morphologically described and illustrated. The ecology of nematode-trapping fungi is expertly presented: their occurrence and habitats, their geographical and seasonal distribution and the effects of soil conditions and nematode density on their distribution all feature amongst the relevant themes. Further chapters examine the use of nematode-trapping fungi in biological control and the authors consider nematicidal activities in detail, exploring the many compounds from fungi that feature in nematicidal activities and of course useful paths for further study on this topic. This is a highly informative and carefully presented book, providing scientific insight for scholars with an interest in fungi and in biological control of nematodes.
