Book Description
Biology of Plant Litter Decomposition, Volume 1 focuses on decomposition of various types of litter, which include all plant remains, ranging from still standing dead trees to the decomposing hyphae of fungi and bacterial cells, including herbivore dung. The book is organized into seven chapters, each devoted to a specific type of litter including lower plants, herbaceous, angiosperm, and coniferous tree leaf litters; wood; root; and digested litter. It describes the structure and function of the organisms concerned. It also covers the involvement of biotrophic and necrotrophic parasites of higher plants in the early stages of decomposition. With a strong focus on the interrelationships in plant litter decomposition, the book is an ideal source of information for research biologists who are interested in life cycle and decomposition of plants.

Book Description
Climate models have evolved into Earth system models with representation of the physics, chemistry, and biology of terrestrial ecosystems. This companion book to Gordon Bonan's Ecological Climatology: Concepts and Applications, Third Edition, builds on the concepts introduced there, and provides the mathematical foundation upon which to develop and understand ecosystem models and their relevance for these Earth system models. The book bridges the disciplinary gap among land surface models developed by atmospheric scientists; biogeochemical models, dynamic global vegetation models, and ecosystem demography models developed by ecologists; and ecohydrology models developed by hydrologists. Review questions, supplemental code, and modeling projects are provided, to aid with understanding how the equations are used. The book is an invaluable guide to climate change and terrestrial ecosystem modeling for graduate students and researchers in climate change, climatology, ecology, hydrology, biogeochemistry, meteorology, environmental science, mathematical modeling, and environmental biophysics.

Book Description
This textbook explores the complex nature of soil biological communities and their environments, and covers deserts, rainforests, seasonal tropical forests, dry deciduous forests, and island environments in the tropical zone. It provides essential information on soil biology concepts, ecological processes, plant-soil feedback, trophic structure, and land use effects on soil’s biological properties. The book also offers an updated approach to soil biota and microbiota and their interactions with plants that regulate the structures and functions of tropical ecosystems. Uniquely, it addresses island environments and natural disasters, shedding new light on soil organisms recovering tropical ecosystem functions. Further topics include ecological processes, plant-soil interactions, trophic communities, molecular approaches, and land use, making the book a valuable asset for students, educators and researchers engaged in the Environmental Sciences, Biodiversity and Conservation, Soil Ecology, Soil Biology, Ecology, Zoology, and Soil Biota Classification using classical and molecular tools.

Book Description
Invertebrates perform such vital roles in global ecosystems—and so strongly influence human wellbeing—that biologist E.O. Wilson was prompted to describe them as “little things that run the world.” As they are such powerful shapers of the world around us, their response to global climate change is also pivotal in meeting myriad challenges looming on the horizon—everything from food security and biodiversity to human disease control. This book presents a comprehensive overview of the latest scientific knowledge and contemporary theory relating to global climate change and terrestrial invertebrates. Featuring contributions from top international experts, this book explores how changes to invertebrate populations will affect human decision making processes across a number of crucial issues, including agriculture, disease control, conservation planning, and resource allocation. Topics covered include methodologies and approaches to predict invertebrate responses, outcomes for disease vectors and ecosystem service providers, underlying mechanisms for community level responses to global climate change, evolutionary consequences and likely effects on interactions among organisms, and many more. Timely and thought-provoking, Global Climate Change and Terrestrial Invertebrates offers illuminating insights into the profound influence the simplest of organisms may have on the very future of our fragile world.

Book Description
The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.
