Mycorrhizal Dynamics in Ecological Systems


Book Description

Mycorrhizae are mutualisms between plants and fungi that evolved over 400 million years ago. This symbiotic relationship commenced with land invasion, and as new groups evolved, new organisms developed with varying adaptations to changing conditions. Based on the author's 50 years of knowledge and research, this book characterizes mycorrhizae through the most rapid global environmental changes in human history. It applies that knowledge in many different scenarios, from restoring strip mines in Wyoming and shifting agriculture in the Yucatán, to integrating mutualisms into science policy in California and Washington, D.C. Toggling between ecological theory and natural history of a widespread and long-lived symbiotic relationship, this interdisciplinary volume scales from structure-function and biochemistry to ecosystem dynamics and global change. This remarkable study is of interest to a wide range of students, researchers, and land-use managers.




The Ecology of Mycorrhizae


Book Description

A great many terrestrial plants live in close association with fungi. The features of this association, which is known as mycorrhiza, are those of a mutualistic symbiosis. Almost all plants from mycorrhizae whereby the fungus provides soil resources to the plant in exchange for energy provided by the plant. The symbiosis means greater productivity under stress for the plant and a steady energy supply for the fungus. This book addresses the diverse and complex ways in which mycorrhizae affect the mechanism for plant survival as individuals and populations, for community structure and functioning. An evolutionary/ecological approach is used to describe how and under what conditions mycorrhizal symbioses range from managing natural and agricultural lands to biotechnological processes that enhance agricultural productivity and sustainability. The Ecology of Mycorrhizae will be an invaluable book, applicable to all levels of theoretical and applied research in agronomy, botany, ecology, environmental microbiology, and plant pathology.

Mycorrhizal Symbiosis is recognized as the definitive work in this area. Since the last edition was published there have been major advances in the field, particularly in the area of molecular biology, and the new edition has been fully revised and updated to incorporate these exciting new developments. Over 50% new material Includes expanded color plate section Covers all aspects of mycorrhiza Presents new taxonomy Discusses the impact of proteomics and genomics on research in this area




Mycorrhiza in Tropical and Neotropical Ecosystems


Book Description

Mycorrhizal symbiosis is a mutualistic association of plant roots and fungi that plays a major role in ecosystem function and diversification, as well as its stability and productivity. It also plays a key role in the biology and ecology of forest trees, affecting growth, water and nutrient absorption and protection against soil-borne pathogens. However, the mycorrhizal research in tropical and neotropical ecosystems remains largely unexplored despite its importance in tropical and neotropical ecosystems. These ecosystems represent more than 0.6% of the total land ecosystems and they have a crucial role in the Earth’s biogeochemical cycling and climate. Threats to tropical forest biodiversity should therefore encourage investigations and inventories of mycorrhizal diversity, function and ecology in tropical latitudes because they concern ecologically and economically important plant species. This Research Topic aims to provide an overview of the knowledge of mycorrhizal symbioses in tropical and neotropical ecosystems. For this Research Topic, we welcome articles that address the diversity, ecology and function of mycorrhiza associated with plants, the impacts of mycorrhiza on plant diversity and composition, the regeneration and dynamics of ecosystems, and biomass production in ecosystems.

Mycorrhizal Networks


Book Description

The last 25 years have seen significant advances in our understanding of the mycorrhizal fungi that colonize most of the world’s plants, and the mycorrhizal networks that form and extend into the soil beyond plant roots. In addition to a thorough review of recent research on mycorrhizal networks, this book provides readers with alternative perspectives. The book is organized into three sections: Network Structure, Nutrient Dynamics, and the Mutualism-Parasitism Continuum. Chapter 1 addresses the specificity of ectomycorrhizal symbionts and its role in plant communities, and provides an updated list of terms and definitions. Chapter 2 explores interactions between symbionts in mycorrhizal fungi networks, as well as interactions between fungal individuals. The second section of the book begins with the examination in Chapter 3 of extramatrical mycelium (mycelia beyond the root tips) in ectomycorrhizal fungi, focused on carbon and nitrogen. Chapter 4 reviews the influence of mycorrhizal networks on outcomes of plant competition in arbuscular mycorrhizal plant communities. Chapter 5 discusses nutrient movement between plants through networks with a focus on the magnitude, fate and importance of mycorrhiza-derived nutrients in ectomycorrhizal plants. Section 3 opens with a review of research on the role of ectomycorrhizal networks on seedling establishment in a primary successional habitat, in Chapter 6. The focus of Chapter 7 is on facilitation and antagonism in arbuscular mycorrhizal networks. Chapter 8 explores the unique networking dynamic of Alnus, which differs from most ectomycorrhizal plant hosts in forming isolated networks with little direct connections to networks of other host species in a forest. Chapter 9 argues that most experiments have not adequately tested the role of mycorrhizal networks on plant community dynamics, and suggests more tests to rule out alternative hypotheses to carbon movement between plants, especially those that include experimental manipulations of the mycorrhizal networks. Plant ecologists have accumulated a rich body of knowledge regarding nutrient acquisition by plants. The editor proposes that research indicating that mycorrhizal fungi compete for nutrients, which are then delivered to multiple hosts through mycorrhizal networks, represents an important new paradigm for plant ecologists.




Mycorrhizal Mediation of Soil


Book Description

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

The Mycorrhizae


Book Description

Many plants benefit greatly from symbiotic relationship with soil fungi known as mycorrhizal fungi. These fungi live on and in the root systems of plants and provide nutrients to the plant in exchange for carbohydrates exuded by the plants. Some of the ecological uses of mycorrhizae include (i) enchancing plant growth and disease resistance (ii) improving transplant success (iii) building soil structure (iv) reducing fertilizer dependency and (v) accelerating revegetation of degraded lands. While over 80 percent of the terrestrial plants show mycorrhizal association, the depth of its application towards industries seems to be under-exploited. Moreover, severe deforestation and land degradation have removed the host plants from the habitats giving way to loss of diversity of the mycorrhizal fungi. Particularly, this problem is acute in the tropical region of the world, where various naturals calamities such as floods, landslides, fire, etc in addition to the human exploitation of natural resources have degraded the major part of the ecosystems. Although, causes are known, Strategies to rebuild the degraded systems remain bliss. There are many national and international journals that bring out the information about the mycorrhizal fungi and their symbiotic relationship with plants but the recent knowledge is almost in scattered state. This scattered information could be kept in a book to provide up-to-date information about mycorrhizal research especially being done in different corner of India. This book is a very selective monograph on mycorrhizae covering its different aspects. It is excellent collection of 21 articles dealing with different disciplines of mycorrhizae and mycorrhizal research carried out by Indian scientists. In order to consummate the collective ideas on mycorrhizal association, its diversity and applications, a number of themes have been identified for this book, including (i) Biodiversity and Ecological issues on mycorrhizal association (ii) Physiology and molecular biology of plant-mycorrhizal fungal interactions (iii) Potential industrial applications. It is doubtless to say that this book would be very useful to all scientists, teachers, students and readers whosoever in interested on mycology and mycological literature.
