Book Description
In this study we report on changes in the belowground ectomycorrhizal fungal communities in southern Swedish coniferous forests as a consequence of liming with 3?7 ton limestone per hectare 16 years prior to the study. A total of 107 ectomycorrhizal fungi were identified from 969 independently sampled root tips by sequencing the internal transcribed spacer region of the ribosomal DNA. Forty, 59 and 51 species were identified in three pine and spruce forests. Within all sites only about 25% of the species overlapped between the limed and the reference areas. However, the most abundant species were often found in both limed and reference plots and 60?70% of the root tips at each site were colonised by species occurring in both limed and reference plots. Across all three sites, fungal species belonging to the genus Tylospora and the order Pezizales became significantly more frequent in limed plots, while species belonging to the genera Russula and Lactarius decreased in frequency. At individual sites, several species within the genera Amphinema, Piloderma, Inocybe and Hygrophorus were also significantly influenced by liming. We estimate that, at the root tip level, about 30% of the roots were colonised by a different fungal species as a consequence of liming. The observed shift in ectomycorrhizal fungal communities was related to an increased pH and base saturation with liming. We conclude that even a moderate level of liming have long lasting effects on belowground ectomycorrhizal community composition. We discuss the observed community changes in relation to ectomycorrhizal functionality and biodiversity in limed forests.

Book Description
The Fungal Community: Its Organization and Role in the Ecosystem, Third Edition addresses many of the questions related to the observations, characterizations, and functional attributes of fungal assemblages and their interaction with the environment and other organisms. This edition promotes awareness of the functional methods of classification over taxonomic methods, and approaches the concept of fungal communities from an ecological perspective, rather than from a fungicentric view. It has expanded to examine issues of global and local biodiversity, the problems associated with exotic species, and the debate concerning diversity and function. The third edition also focuses on current ecological discussions - diversity and function, scaling issues, disturbance, and invasive species - from a fungal perspective. In order to address these concepts, the book examines the appropriate techniques to identify fungi, calculate their abundance, determine their associations among themselves and other organisms, and measure their individual and community function. This book explains attempts to scale these measures from the microscopic cell level through local, landscape, and ecosystem levels. The totality of the ideas, methods, and results presented by the contributing authors points to the future direction of mycology.

Book Description
Mycorrhiza - the symbiosis between plants and fungi - plays a key role in plant life. This book reviews for the first time the current knowledge of 15 individual genera of ectomycorrhizal fungi. It is unique in that each chapter is dedicated to a single fungal genus, each written by internationally recognized experts on the respective fungal genera. It is thus an invaluable reference source for researchers, students and practitioners in the fields of mycorrhizal biology, mycology, forestry, plant sciences and soil biology.

Book Description
Recent years have seen extensive research in the molecular underpinnings of symbiotic plant-fungal interactions. Molecular Mycorrhizal Symbiosis is a timely collection of work that will bridge the gap between molecular biology, fungal genomics, and ecology. A more profound understanding of mycorrhizal symbiosis will have broad-ranging impacts on the fields of plant biology, mycology, crop science, and ecology. Molecular Mycorrhizal Symbiosis will open with introductory chapters on the biology, structure and phylogeny of the major types of mycorrhizal symbioses. Chapters then review different molecular mechanisms driving the development and functioning of mycorrhizal systems and molecular analysis of mycorrhizal populations and communities. The book closes with chapters that provide an overall synthesis of field and provide perspectives for future research. Authoritative and timely, Molecular Mycorrhizal Symbiosis, will be an essential reference from those working in plant and fungal biology.
