Soil Biota, Fungi, and Mycorrhizae
Reforestation of Bauxite Mine Spoils with Eucalyptus tereticornis Sm. Seedlings Inoculated with Arbuscular Mycorrhizal FungibackgroundIn the Yercaud hills of the Salem Distict, Tamil Nadu, India, the authors investigated the feasibility of using trees inoculated with beneficial mycorrhizae as an alternative to the traditional and more expensive method of spreading topsoil before planting Open access copy available |
Nitrogen Dynamics of Actinorhizal Casuarina Forest Stands and its Comparison with Alnus and Leucaena ForestsBackgroundNitrogen plays a key role in soil fertility and plant productivity. Therefore, in regions in which deforestation has increasingly led to savannization and desertification, afforestation by fast-growing, n-fixing tree species is preferable. This study examines the characteristics of nitrogen fixing trees. Research Goals & MethodsThe nitrogen retention rates of three dry tropical forest tree species were measured, by examining rates of N cycling through vegetation, litter and soil pools.

Impacts of Early- and Late-seral Mycorrhizae during Restoration in Seasonal Tropical Forest, MexicobackgroundThis study examines the degree to which arbuscular mycorrhizal fungi (AMF) are associated with early vs. late successional forests in Quintana Roo, Mexico. It considers how such fungi aid seedling growth of six native early-, mid- or late-successional tree species. The researchers hypothesize that the application of mycorrizae associated with a tree species' associated successional sere will better promote that species' seedling growth and that associated AMF are therefore key for forest restoration success in degraded or disturbed areas.

Los hongos micorrízicos arbusculares y su implicación en la producción y manejo de especies neotropicales forestales, con énfasis en meliáceas (Arbuscular mycorrhizal fungi and its use in the production and management of neotropical forest)EspañolAntecedentesLos hongos micorrízicos arbusculares (HMA) tienen implicaciones importantes en la producción de bosques tropicales, principalmente en especies de Meliaceae nativas de América Latina, como Cedrela odorata y Swietenia macrophylla. Estas especies son muy valoradas por la calidad de su madera, aunque el establecimiento de plantaciones comerciales y la reforestación en general no ha sido cien porciento exitosa. Existe un interés creciente en estudiar el papel de la HMA en la rehabilitación y restauración forestal debido a su capacidad para mejorar la adaptación y supervivencia de las plantas en condiciones adversas.

Performance of an Improved Fallow System in the Peruvian Amazon—Modelling ApproachbackgroundThis research compares the ecological and economic potential of an improved leguminous tree fallow (using Inga edulis) to the traditional grass fallow (dominated by Imperata brasiliensis) in central Peru.

Plant Growth-Promoting Bacteria: A Potential Tool for Arid Mangrove ReforestationbackgroundMicrobes (bacteria and fungi) play a crucial role in nutrient recycling in mangrove systems, which are nutrient deficient. Microbes make nutrients, especially nitrogen and phosphorous, available to mangroves, while mangroves may improve soil conditions for microbes (for example, by oxidizing the soil). PGPB may be nitrogen fixers, phosphate solubilizers, mineral uptake enhancers, and phytopathogen controllers. Available with subscription or purchase |
Application of Mycorrhizal Roots Improves Growth of Tropical Tree Seedlings in the Nursery: A Step Towards Reforestation with Native Species in the Andes of EcuadorbackgroundEcuador’s tropical mountain rainforests are rich in biodiversity but are facing the highest deforestation rate in South America (1.7%). Tree plantations are one method being used to restore these forests, however these plantations often use fast-growing introduced species rather than native species. To improve the success of native species in order to encourage their greater use in plantations, this study proposes inoculation of nursery seedlings with the arbuscular mycorrhizal (AM) fungi that is associated with these native species in the forest.
