Download or read book Biogeography of Mycorrhizal Symbiosis written by Leho Tedersoo and published by Springer. This book was released on 2017-06-01 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a timely overview and synthesis of biogeographic patterns of plants and fungi and their mycorrhizal associations across geographic scales. Written by leading experts in the field, it provides an updated definition of mycorrhizal types and establishes the best practices of modern biogeographic analyses. Individual chapters address the basic processes and mechanisms driving community ecology, population biology and dispersal in mycorrhizal fungi, which differ greatly from these of prokaryotes, plants and animals. Other chapters review the state-of-the-art knowledge about the distribution, ecology and biogeography of all mycorrhizal types and the most important fungal groups involved in mycorrhizal symbiosis. The book argues that molecular methods have revolutionized our understanding of the ecology and biogeography of mycorrhizal symbiosis and that rapidly evolving high-throughput identification and genomics tools will provide unprecedented information about the structure and functioning of mycorrhizal symbiosis on a global scale. This volume appeals to scientists in the fields of plant and fungal ecology and biogeography.

Book excerpt: Discover neglected wild food sources—that can also be used as medicine! The long-standing notion of “food as medicine, medicine as food,” can be traced back to Hippocrates. Eating and Healing: Traditional Food As Medicine is a global overview of wild and semi-domesticated foods and their use as medicine in traditional societies. Important cultural information, along with extensive case studies, provides a clear, authoritative look at the many neglected food sources still being used around the world today. This book bridges the scientific disciplines of medicine, food science, human ecology, and environmental sciences with their ethno-scientific counterparts of ethnobotany, ethnoecology, and ethnomedicine to provide a valuable multidisciplinary resource for education and instruction. Eating and Healing: Traditional Food As Medicine presents respected researchers’ in-depth case studies on foods different cultures use as medicines and as remedies for nutritional deficiencies in diet. Comparisons of living conditions in different geographic areas as well as differences in diet and medicines are thoroughly discussed and empirically evaluated to provide scientific evidence of the many uses of these traditional foods as medicine and as functional foods. The case studies focus on the uses of plants, seaweed, mushrooms, and fish within their cultural contexts while showing the dietary and medical importance of these foods. The book provides comprehensive tables, extensive references, useful photographs, and helpful illustrations to provide clear scientific support as well as opportunities for further thought and study. Eating and Healing: Traditional Food As Medicine explores the ethnobiology of: Tibet—antioxidants as mediators of high-altitude nutritional physiology Northeast Thailand—“wild” food plant gathering Southern Italy—the consumption of wild plants by Albanians and Italians Northern Spain—medicinal digestive beverages United States—medicinal herb quality Commonwealth of Dominica—humoral medicine and food Cuba—promoting health through medicinal foods Brazil—medicinal uses of specific fishes Brazil—plants from the Amazon and Atlantic Forest Bolivian Andes—traditional food medicines New Patagonia—gathering of wild plant foods with medicinal uses Western Kenya—uses of traditional herbs among the Luo people South Cameroon—ethnomycology in Africa Morocco—food medicine and ethnopharmacology Eating and Healing: Traditional Food As Medicine is an essential research guide and educational text about food and medicine in traditional societies for educators, students from undergraduate through graduate levels, botanists, and research specialists in nutrition and food science, anthropology, agriculture, ethnoecology, ethnobotany, and ethnobiology.
Download or read book Psammic Peinobiomes written by Joseph Alfred Zinck and published by Springer Nature. This book was released on 2023-09-30 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book represents a multidisciplinary approach to understanding soil–landscape–vegetation relationships and, specifically, the ecophysiology of plant communities developing on sandy soils of very low fertility that are subject to seasonal flooding. It provides an overview of the white sand ecosystems within the Amazon basin, and focuses on the forest and herbaceous (meadows) vegetation growing on the dystrophic sandy soils of the upper Negro and Orinoco river basins. Several chapters describe physiographic aspects of the study area using integrated remote sensing and in situ sampling. By doing so they attain a comprehensive description of the origin and evolution of soils and landscapes, an advanced classification of soils, and a mapping of the geographic distribution of psammophilous vegetation. This volume also provides a phytosociological classification of extensive forested areas, and a detailed description of the structure and diversity of little-known herbaceous formations.It targets professionals in the fields of ecology, ecophysiology, geomorphology, soils, vegetation, and the environmental sciences. The information it offers may be of significant use to researchers, protected area planners, and environmental policy makers.

Book excerpt: Fungi of Cameroon is a contribution towards assessing the current macrofungal diversity associated with the ecosystems of Cameroon's southern forests, and evaluates the impact of deforestation and slash-and-burn on fungal communities and tracks the occurrence and changes to the fungal communities through the seasonal climatic variations (rainfall). The overall recorded species were new to the Mbalmayo forest reserve, while 75 of the described species were new to Cameroon, and eleven new mycobiota were described, plus one combination. The greatest fungal diversity was observed in forest stands, declining towards fallows and cropland. A distinct reduction of the diversity of wood and litter-dependent fungal species can be observed where land conversion takes place which is a definite threat to fungal species. As expected, seasonal variations fundamentally influence and govern the fruition and composition of the fungal communities studied.

Download or read book Conserving Biological Diversity in Managed Tropical Forests written by Jill M. Blockhus and published by IUCN. This book was released on 1992 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the meeting of the International Tropical Timber Organization held in Bali in 1990, ITTO adopted the target of ensuring that all tropical timber marketed internationally should, by the year 2000, come from forests that are managed sustainably. This study is an attempt to determine whether the member countries of the ITTO have a legal and administrative basis for managing their production forests in ways which will allow these forests to contribute to biological diversity conservation. It also attempts to assess the extent to which such management is already applied on the ground through member country studies. A set of guidelines on ways in which management of production forests could be improved is included.
Download or read book Mycorrhizal Associations Shape Complex Plant soil Interactions in the Early Seedling Recruitment of Bornean Rainforest Trees written by Richard Maxfield Segnitz and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic feedbacks between plants and soil fungi have been shown to influence seedling recruitment and plant community structure. This dissertation is principally concerned with how mycorrhizal associations influence such feedbacks as experienced by tropical tree seedlings, how soil fertility might change these interactions, and how the fungal communities that drive feedbacks assemble on seedling roots. While work in temperate forests suggests that there are consistent differences in plant-soil feedback between plants with arbuscular and ectomycorrhizal associations, it is unclear whether these differences exist in diverse tropical rainforests or how they may be impacted by heterogeneity in soil nutrients. In this dissertation, I address several current knowledge gaps by examining how plant-soil feedbacks operate in a diverse but ectomycorrhizal dominated rainforest in Northern Borneo. I conducted a shadehouse experiment (Chapters 1 & 2) using a design that allowed me to test whether the direction and strength of plant-soil feedback depends on a tree species' mycorrhizal association type, phylogenetically driven variation in the soil microbiota, and the fertility of the soil. I established a large scale multispecies shadehouse experiment in which the edaphic and biotic origins of soils were manipulated. I found that phylogenetically structured plant-soil feedbacks could influence seedling performance, but did so differently for ectomycorrhizal and arbuscular mycorrhizal seedlings (Chapter 1). Further, I found that soil resource availability changed the strength and direction of feedbacks for arbuscular mycorrhizal hosts but not ectomycorrhizal hosts. Using environmental DNA sequencing to characterize root-associated fungi in this experiment (Chapter 2), I showed that root-associated fungal communities differed at broad taxonomic scales across host mycorrhizal types but were similarly structured by host identity and soil type at finer scales. Further, I show that evolutionary relationships between seedlings and the overstory species that condition the soil can predictably affect root community structure, but that this effect differed depending on seedling mycorrhizal type, providing a possible mechanism by which plant-soil feedbacks is mediated. In my final chapter, I examine plant-soil feedbacks in a field experiment that focused on a single ectomycorrhizal seedling species. I explored how plant-soil feedbacks interact with density-dependent seedling mortality across the landscape in the field (Chapter 3). I found that seedlings of this species might weakly benefit from recruitment near conspecific adults and were likely not subject to conspecific negative density dependence typically thought to limit recruitment in tropical forests. I found that local scale density-dependence in seedling mortality did not vary with proximity to conspecific adults, suggesting that for this species the predominant effects on growth and mortality might be driven more by variation in the presence of beneficial soil biota than natural enemies. The results of this thesis collectively suggest that mycorrhizal associations of tropical trees play an important role in shaping how complex plant-soil interactions affect early seedling recruitment and, ultimately, tropical tree diversity. I found that species' mycorrhizal type shaped the feedbacks they experienced in a diverse Bornean rainforest, and also that mycorrhizal type could affect how the overstory canopy shapes root fungal communities. Further, the impact of overstory canopy composition on seedling growth can be dependent on both mycorrhizal type and edaphic heterogeneity.
