Development of Soilless Culture Methods for Production of Moringa (Moringa oleifera Lam.) Root and Leaf BiomassbackgroundMoringa is a valuable tropical agroforestry species with a fruit rich in nutrients. This study tested soilless (hydroponic) Moringa cultivation methods given that past research on tissue culture (vegetative reproduction) has shown difficulty in transfer to soil. Research Goals & MethodsIn this study, dehulled seeds had a high germination rate (65%), whereas hulled seeds had low germination. Available with subscription or purchase |
Propagación in vitro de material seleccionado de Tabebuia rosea y Cordia alliodora (In vitro propagation of selected material from Tabebuia rosea and Cordia alliodora)EspañolAntecedentesLa aplicación de la micropropagación y otras técnicas biotecnológicas a las especies forestales maderables ha representado un enfoque útil para aumentar el número de plantas necesarias para el establecimiento de plantaciones de restauración. En Colombia se está investigando la integración de esta tecnología para la siembra de importantes especies maderables nativas como Tabebuia rosea y Cordia alliodora. Open access copy available |
Apuntes sobre algunas especies forestales nativas de la sierra Peruana (Notes about several forest native species from the highlands of Peru)EspañolAntecedentesDesde 1860, la reforestación en la Sierra Peruana se realizó principalmente con Eucalipto, cambiando a Pinus radiata durante las décadas de 1950-1970. La necesidad de reforestar tierras mas elevadas, despertó el interés por la propagación y uso de especies forestales nativas las cuales se encuentran mejor adaptadas a estas condiciones y presentan diversos usos y beneficios.

Seed Dispersal and Potential Forest Succession in Abandoned Agriculture in Tropical AfricaBackgroundForest succession on disturbed and post-agrarian lands is often slow because the resources necessary for succession – such as soil nutrients, seeds, and moisture – are depleted. In such areas, succession may depend on bat- and bird-dispersed seeds arriving from distant forest patches. Open access copy available |
Seeing the fruit for the trees in BorneoBackgroundLowland dipterocarp tropical rainforests reproduce during infrequent community-wide events known as ‘general flowering.’ These unpredictable cycles, thought to be influenced by El Niño cycles, are the primary reproductive driver across this forest type. During a time of rapid deforestation across the highly diverse, but highly sensitive, dipterocarp-dominated landscape of Borneo, capitalizing on general flowering is critical for seed collection for restoration efforts and for species preservation.

Environmental Drivers in Mangrove Establishment and Early Development: A reviewbackgroundThis study reviews literature on the environmental conditions that influence the establishment and early growth of mangroves. Research Goals & MethodsDifferent species grow in areas with different flooding regimes. The authors used the classification of "inundation by all high tides, inundation by medium high tides, inundation by normal high tides, inundation by spring tides, and occasional inundation by exceptional or equinoctial tides."

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.
