Enriquecimiento de plantaciones forestales como herramienta para la rehabilitación de ambientes degradados en la region sur Ecuatoriana (Enrichment and rehabilitation of degraded environments in southern Ecuador)EspañolAntecedentesEl estudio analiza el potencial de adaptación de especies nativas a las condiciones de plantaciones de Pinus patula, en una plantación cerca de la Estación Científica San Francisco en la región sur del Ecuador. Objetivos y MetodologíaEl trabajo estudia dos micro-ambientes: claros y bajo dosel de plantación, instalando cuatro parcelas en cada uno de ellos, con un total de 648 individuos de nueve especies nativas.

Tree biodiversity in farmer cooperatives of a shade coffee landscape in western El SalvadorbackgroundConservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. Understanding the types of biodiversity common in agriculturally managed lands, and involving farmers in conservation planning, is important for regional conservation goals.

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.

Awacachi Biological Corridor ReforestationBACKGROUNDThe mission of the project is to propagate native trees species along the Awacachi biological corridor as well as the agroforestry areas in the buffer zone. The project to conserve and restore in the corridor was established in 2000 and spans 10,000 hectares. The Awacachi Corridor is a key strategic site which along with adjoining areas, reinforces the conservation of humid tropical forest of the Chocó biogeographic region. Open access copy available |
Species-Rich but Distinct Arbuscular Mycorrhizal Communities in Reforestation Plots on Degraded Pastures and in Neighboring Pristine Tropical Mountain Rain ForestbackgroundThis study compares the arbuscular mycorrhizal fungi (AMF) of 4 native species saplings growing in three types of fire-degraded pasture (recently abandoned, bracken covered, and shrub covered pasture) to the AMF richness and composition of 30 adult tree species in neighboring primary forest. Research Goals & MethodsThe authors sequenced a segment of fungal 18S rDNA from the mycorrhizas; in total, 193 glomeromycotan sequences were analyzed, with 130 of them being published for the first time.
