"This book is a first attempt to bring together information on the biodiversity of microfungi in the tropics, with emphasis on the ascomycetes and deuteramycetes. Microfungi in the tropics are relatively unknown, yet they probably constitute the majority of the world's fungi. By presenting comprehensive, timely and truly international reviews of important groups of tropical microfungi, this volume provides an important baseline for future studies on fungal diversity. The aim is to stimulate interest into the fungi in the tropics and illustrate the variety, importance and potential use of these exceptional organisms."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

In the last few decades more and more yeast habitats have been explored, spanning cold climates to tropical regions and dry deserts to rainforests. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. Recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.
The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.
Biodiversity of Fungi is essential for anyone collecting and/or monitoring any fungi. Fascinating and beautiful, fungi are vital components of nearly all ecosystems and impact human health and our economy in a myriad of ways. Standardized methods for documenting diversity and distribution have been lacking. A wealth of information, especially regrading sampling protocols, compiled by an international team of fungal biologists, make Biodiversity of Fungi an incredible and fundamental resource for the study of organismal biodiversity. Chapters cover everything from what is a fungus, to maintaining and organizing a permanent study collection with associated databases; from protocols for sampling slime molds to insect associated fungi; from fungi growing on and in animals and plants to mushrooms and truffles. The chapters are arranged both ecologically and by sampling method rather than by taxonomic group for ease of use. The information presented here is intended for everyone interested in fungi, anyone who needs tools to study them in nature including naturalists, land managers, ecologists, mycologists, and even citizen scientists and sophiscated amateurs. - Covers all groups of fungi - from molds to mushrooms, even slime molds - Describes sampling protocols for many groups of fungi - Arranged by sampling method and ecology to coincide with users needs - Beautifully illustrated to document the range of fungi treated and techniques discussed - Natural history data are provided for each group of fungi to enable users to modify suggested protocols to meet their needs
From earliest times, human beings have noticed patterns in nature: night and day, tides and lunar cycles, the changing seasons, plant succession, and animal migration. While recognizing patterns conferred great survival advantage, we are now in danger from our own success in multiplying our numbers and altering those patterns for our own purposes. It is imperative that we engage again with the patterns of nature, but this time, with awareness of our impact as a species. How will burgeoning human populations affect the health of ecosystems? Is loss of species simply a regrettable byproduct of human expansion? Or is the planet passing into a new epoch in just a few human generations? Nature and Human Society presents a wide-ranging exploration of these and other fundamental questions about our relationship with the environment. This book features findings, insights, and informed speculations from key figures in the field: E.O. Wilson, Thomas Lovejoy, Peter H. Raven, Gretchen Daily, David Suzuki, Norman Myers, Paul Erlich, Michael Bean, and many others. This volume explores the accelerated extinction of species and what we stand to lose--medicines, energy sources, crop pollination and pest control, the ability of water and soil to renew itself through biological processes, aesthetic and recreational benefits--and how these losses may be felt locally and acutely. What are the specific threats to biodiversity? The book explores human population growth, the homogenization of biota as a result in tourism and trade, and other factors, including the social influences of law, religious belief, and public education. Do we have the tools to protect biodiversity? The book looks at molecular genetics, satellite data, tools borrowed from medicine, and other scientific techniques to firm up our grasp of important processes in biology and earth science, including the "new" science of conservation biology. Nature and Human Society helps us renew our understanding and appreciation for natural patterns, with surprising details about microorganisms, nematodes, and other overlooked forms of life: their numbers, pervasiveness, and importance to the health of the soil, water, and air and to a host of human endeavors. This book will be of value to anyone who believes that the world's gross natural product is as important as the world's gross national product.
Although biologists have directed much attention to estimating the extent and causes of species losses, the consequences for ecosystem functioning have been little studied. This book examines the impact of biodiversity on ecosystem processes in tropical forests - one of the most species-rich and at the same time most endangered ecosystems on earth. It covers the relationships between biodiversity and primary production, secondary production, biogeochemical cycles, soil processes, plant life forms, responses to disturbance, and resistance to invasion. The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes.
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.
This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity Project, executed by the Tropical Soil Biology and Fertility (TSBF) Institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity and current land uses in terrestrial natural, semi-natural and agroecosystems in tropical forests and at forest margins. The aim is to assess soil biodiversity against current and historic land use practices both at plot and landscape scales and, further, to identify opportunities for improved sustainable land management through the introduction, management or remediation of soil biota, thus reducing the need for external inputs such as fertilizers and pesticides. The book also contains extensive advice on the handling of specimens and the allocation of organisms to strain or functional group type. Published with TSBF-CIAT, CTA, UNEP and GEF
