Book Description
This book, prepared by participants of the European network COST ACTION 810 (1989-93) is the outcome of a meeting held in Switzerland (Einsiedeln, September 29 to October 2, 1993) on the "Impact of arbuscular mycorrhizas on sustainable agriculture and natural ecosystems". COST(Cooperation Scientifique et Technique) Networks were created in 1971 by the Commission of European Communities, and later enlarged to include non-European Member States, to promote pre-competitive scientific and technical research in fields of common interest. During the eighties, COST ACTIONS were launched in bio technological fields, including the network on arbuscular mycorrhizas. Arbuscular mycorrhizas are a universally found symbiosis between plants and certain soil fungi and essential components of soil-plant systems. They act as a major inter face by influencing or regulating resource allocation between abiotic and biotic components of the soil-plant system. Arbuscular mycorrhizas are involved in many key ecosystem processes including nutrient cycling and conservation of soil struc ture, and have been shown to improve plant health through increased protection against abiotic and biotic stresses. Sustainability can be defined as the successful management of resources to satisfy changing human needs while maintaining or enhancing the quality of the environ ment and conserving resources. Increasing environmental degradation and instability, due to anthropogenic activities and in particular the increasing fragility of the soil resource, has led to an increased awareness of the need to develop practices resulting in more sustainable natural and agroecosystems.
Microorganisms in Plant Conservation and Biodiversity

Book Description
Plant conservation is increasingly recognised as an outstanding global priority, yet despite considerable efforts over the last few decades, the number of threatened species continues to rise. The practice of plant conservation has for too long been a rather hit-or-miss mixture of methods. While microorganisms have been recognised as a crucial and essential element in supporting the lifecycles of plant species, there has been limited recognition of the relationships between macro level conservation facilitating ecosystem functioning at the micro level. This book addresses the role of microorganisms in conservation - both their support functions and deleterious roles in ecosystem processes and species survival. Importantly, a number of authors highlight how microbial diversity is, itself, now under threat from the many and pervasive influences of man. What is clear from this volume is that like many contemporary treatments of plant and animal conservation, the solution to mitigate the erosion of biodiversity is not simple. This book represents an attempt to bring to the fore the ecological underwriting provided by microorganisms.

Below-Ground Interactions in Ecological Processes

Languages : en
Pages : 237
Book Description
Aboveground interactions between plants and organisms have served as a foundation of ecological and evolutionary theories. Accumulating evidence suggests that interactions that occur belowground can have immense influence on eco-evolutionary dynamics of plants. Despite the increasing awareness among scientists of the importance of belowground interactions for plant performance and community dynamics, they have received considerably less theoretical and empirical attention compared to aboveground interactions. In this eBook we aim to highlight the overlooked roles of belowground interactions and outline their myriad ecological roles, from affecting soil health through impacting plant interactions with above-ground fauna. This eBook with 18 articles and an Editorial includes conceptual contribution together with original research work. The chapters are exploring the roles of belowground biotic interactions, in the context of ecological processes both below- and above-ground.

Effects of Elevated Atmospheric Carbon Dioxide on the Arbuscular-mycorrhizal Symbiosis at the Host Plant, Plant Community, and Ecosystem Level

Pages : 449
Book Description
There is a new emerging interest in the effects of gaps and patches on succession and biodiversity. This innovative volume is a synthesis of studies of plant responses to temporal and spatial heterogeneity, the exploitation of resources from pulses and patches by plants, and their competition with neighbors in the face of this variability.Aboveground, the book focuses upon the nature of canopy patchiness, consequences of this heterogeneity for the light environment, and the mechanisms by which plants respond to and exploit this patchiness. Belowground, the text explores the heterogeneity of soil environments and how root systems obtain nutrients and water in the context of this temporal and spatial variability. As a new reference in an evolving and growing field, this text is sure to be a valuable tool for researchers and advanced students in plant physiology, ecology, agronomy, and forestry alike.
