Available in PDF, EPUB and Kindle. Book excerpt: Soil Nematodes of Grasslands in Northern China presents research on China’s temperate grasslands, providing the findings and results of a large field survey along a transect across the northern temperate grassland. It examines nematode distribution patterns along the transect from trophic group and family, to genus level, also evaluating their relationship with climatic conditions, plant biomass and soil parameters. The book then presents detailed taxonomy information of nematodes to genus or species level, providing keen insights into nematode diversity along the grassland transect in north China. Final sections review the advances and perspectives for the research of soil ecology on soil nematodes in China, including recent major discoveries of soil microbial diversity and eco-function during this field survey. This work will help researchers predict the impact of global change drivers on below ground soil biota and better understand the functioning and services they provide in terrestrial ecosystems. Features previously unavailable information on nematode diversity and distribution along a large geographic region of China Describes the relationship of nematode assemblage composition with climatic conditions, plant and soil characteristics Covers nematode genera and species descriptions along the grassland transect

Book excerpt: This thesis summarizes the results of five studies investigating the effect of plant species on soil nematode communities in grasslands. Nematodes (roundworms) are ubiquitous members of the soil fauna and have been much used as indicators of soil conditions. Plants have the ability to affect soil organisms through structural modification of the soil habitat and through the quantity and quality of organic matter that is returned to soil, in the form of plant litter and root exudates.

Download or read book Dorylaimida written by M. Shamim Jairajpuri and published by BRILL. This book was released on 2023-11-27 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dorylaimida represent a large and very important group of soil and freshwater inhabiting nematodes of great agricultural importance. Both in appearance and mode of life they represent a wide diversity and as a consequence the number of species and higher taxa that have been described hitherto is the highest within Nematoda. The identification of species, genera, families, etc. of Dorylaimida is very difficult and at times causes problems for the specialist too. The large number of species on the one hand and often the meagre descriptions on the other make even well-known taxonomists to look at Dorylaimida with great hesitation and desperation. M. Shamim Jairajpuri and Wasim Ahmad have undertaken a great task in summarizing, evaluating and systematizing all the knowledge that has been published so far.
Download or read book Soil Fungal Biodiversity for Plant and Soil Health written by Magdalena Frąc and published by Frontiers Media SA. This book was released on 2019-08-22 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi represent a large portion of the biodiversity on Earth and they are key players in soils where they provide numerous ecosystem functions. Soil fungi have pivotal ecological roles influencing plant health as symbionts, pathogens or decomposers. Soil fungal biodiversity is increasingly recognized as providing benefits to soil health as they facilitate if not control numerous ecosystem processes. Continued research on the identity, abundance and distribution of soil fungi, their various roles in context with the differentiation of the soil fungal community are thus fundamental to better understand the dimensions of fungal biodiversity, its impact on plant health as well as the prevention of fungal diseases. This Research Topic aims at collecting contributions that provide taxonomic, physiological and ecological characterizations of soil fungal communities that will aid in the understanding of their biology, their interrelationships as well as the mechanisms that underpin the various ecosystem functions they provide in the soil environment. This Research Topic focusing on environmental mycology encourages in particular to report sensitive, accurate and fast methods for the detection, identification and distribution of fungi, including metagenomics, metatranscriptomics and metabolomics approaches, as they increasingly reveal the impact of fungal biodiversity for soil and plant health.

Download or read book Carbon Sequestration in Agricultural Ecosystems written by Klaus Lorenz and published by Springer. This book was released on 2018-05-31 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive book on basic processes of soil C dynamics and the underlying factors and causes which determine the technical and economic potential of soil C sequestration. The book provides information on the dynamics of both inorganic (lithogenic and pedogenic carbonates) and organic C (labile, intermediate and passive). It describes different types of agroecosystems, and lists questions at the end of each chapter to stimulate thinking and promote academic dialogue. Each chapter has a bibliography containing up-to-date references on the current research, and provides the state-of-the-knowledge while also identifying the knowledge gaps for future research. The critical need for restoring C stocks in world soils is discussed in terms of provisioning of essential ecosystem services (food security, carbon sequestration, water quality and renewability, and biodiversity). It is of interest to students, scientists, and policy makers.
Download or read book Aboveground Belowground Linkages written by Richard D. Bardgett and published by OUP Oxford. This book was released on 2010-07-29 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aboveground-Belowground Linkages provides the most up-to-date and comprehensive synthesis of recent advances in our understanding of the roles that interactions between aboveground and belowground communities play in regulating the structure and function of terrestrial ecosystems, and their responses to global change. It charts the historical development of this field of ecology and evaluates what can be learned from the recent proliferation of studies on the ecological and biogeochemical significance of aboveground-belowground linkages. The book is structured around four key topics: biotic interactions in the soil; plant community effects; the role of aboveground consumers; and the influence of species gains and losses. A concluding chapter draws together this information and identifies a number of cross-cutting themes, including consideration of aboveground-belowground feedbacks that occur at different spatial and temporal scales, the consequences of these feedbacks for ecosystem processes, and how aboveground-belowground interactions link to human-induced global change.

This book was released on 2020-09-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.
