This new book shows the work done by researchers dedicated to the study of different mycorrhizas types, the fungal species associated and their distribution influenced by geographical and environmental factors among the different South American biogeographic regions. The exclusive biotic and abiotic characteristics delimit natural ecosystems with uniques biological communities, where mycorrhizologists have investigated plant symbioses in those ecosystems for decades, providing data from Venezuelan Great Savannah, Andes, Puna, Chaco, Caatinga, Monte, Atlantic Forest, Marginal Forest, Cerrado, Patagonia, Yungas, Rainforest, Andean-Patagonian Forests, and Antarctic section. In these environments, different mycorrhizal associations (arbuscular / ericoid / orchidoid / ectomycorrhizal / mycoheterotrophic) are present in herbaceous plants, shrubs, and trees. Mycorrhizal associations were studied from different researching points of view (biodiversity, biological invasions, biotic / abiotic disturbances, altitudinal variations, seasonal changes, land uses). The aim of this Book is to compile research on mycorrhizal fungi and their associations in environments of South America, throughout the synthesis of information from natural and anthropogenic related environments. The book focuses in different bioregions of South America from tropical areas to the southern cone, and it will be useful to those who work on plant-fungal interactions in different vegetation types and in agricultural lands from South America and worldwide.

In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. Also, changes in land use alter the structure and function of ecosystems where biodiversity is vital in the ecosystem. Soils are a major aid in food production in all terrestrial ecosystems; however, this means they are also involved in gas emission and global warming. Thus, in agronomic ecosystems, several mitigation practices have been proposed to promote the increase of carbon soil stock, and the reduction of warming gas emission from soils. In South America, most of the rural population depends economically on agriculture and usually works in family units. New, organic, safe, and sustainable agro-forestry practices must be applied to support local communities and countries to achieve hunger eradication, rural poverty reduction, and sustainable development. This book compiles new information for mycorrhizal occurrence in natural and anthropic environments in South America. It includes new reports of mycorrhizal fungi diversity along different mycorrhizal types and their effect on plant communities, plant invasions, the use of mycorrhizal fungi for ecological and sustainable studies, management programs of natural and agroecosystems, and forestry and food-secure production. This book fills the gaps in biodiversity knowledge, management and safe food production of mycorrhizas. It should be a valuable help to researchers, professors and students, to aid in use of mycorrhizal fungi while also focusing on their biodiversity, sustainable safe food production, and conservation perspectives.
