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.

Available in PDF, EPUB and Kindle. Book excerpt: A field experiment and two soil faunal surveys were carried out to determine the effect of liming on earthworm populations of European forests. In the UK, a mixed species assemblage of earthworms was introduced into a deep peat soil under a young stand of Picea sitchensis, following addition of lime. Dendrodrilus rubidus was the only introduced species to be recovered after nearly a year. Total earthworm numbers and biomass were 70% and 15% of those introduced; this included species which had not been inoculated. Earthworms were found only where the soil had been limed; most individuals were found where earthworms and lime had been applied. In a survey of long-established limed plots of Picea abies on an acid, brown earth soil in northern France, liming increased earthworm density (5 to 11 individuals m-2, compared with 6 m-2 in a nearby deciduous woodland, and 0 m-2 in unlimed P. abies plots). Similarly, in Northern Ireland, the addition of lime permitted a substantial community of earthworms to develop in deep peat soil under P. sitchensis (79 individuals m-2, compared with 5 m-2 in unlimed soils), including acid intolerant species rare in coniferous soils. Different species assemblages were found in the four different limed plots sampled. The trees growing on limed soil at this site showed greater height growth than the trees in the unlimed plots, and it is suggested that earthworms have a beneficial effect in limed coniferous soils by increasing nutrient turnover.

Download or read book Nutrient Acquisition by Plants written by Hormoz BassiriRad and published by Springer Science & Business Media. This book was released on 2005-12-30 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an integrated review of the mechanisms controlling plant nutrient uptake and how plants respond to changes in the environment. Among key topics covered are: soil nutrient bioavailability; root responses to variations in nutrient supply; nitrogen fixation; root architecture; life span; mycorrhizae; responses to climate change. The book helps us understand the mechanisms that govern present-day plant communities and to predict the response of plants to a changing climate.

This book was released on 2008-07-27 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal fungi are microbial engines which improve plant vigor and soil quality. They play a crucial role in plant nutrient uptake, water relations, ecosystem establishment, plant diversity, and the productivity of plants. Scientific research involves multidisciplinary approaches to understand the adaptation of mycorrhizae to the rhizosphere, mechanism of root colonization, effect on plant physiology and growth, biofertilization, plant resistance and biocontrol of plant pathogens. This book discusses and goes into detail on a number of topics: the molecular basis of nutrient exchange between arbuscular mycorrhizal (AM) fungi and host plants; the role of AM fungi in disease protection, alleviation of soil stresses and increasing grain production; interactions of AM fungi and beneficial saprophytic mycoflora in terms of plant growth promotion; the role of AM fungi in the restoration of native ecosystems; indirect contributions of AM fungi and soil aggregation to plant growth and mycorrhizosphere effect of multitrophic interaction; the mechanisms by which mycorrhizas change a disturbed ecosystem into productive land; the importance of reinstallation of mycorrhizal systems in the rhizosphere is emphasized and their impact on landscape regeneration, and in bioremediation of contaminated soils; Ectomycorrhizae (ECM) and their importance in forest ecosystems and associations of ECM in tropical rain forests function to maintain tropical monodominance; in vitro mycorrhization of micro-propagated plants, and visualizing and quantifying endorhizal fungi; the use of mycorrhizae, mainly AM and ECM, for sustainable agriculture and forestry.
