Enrichment Planting of Bertholletia excelsa in Secondary Forest in the Bolivian Amazon: Effect of Cutting Line Width on Survival, Growth and Crown TraitsbackgroundBertholletia excelsa (Brazil nut tree) seedlings were planted as enrichment plantings under a variety of different treatments in the El Tigre reserve in the northern Bolivian Amazon. Research Goals & MethodsSurvival and growth were measured for five treatments: cutting lines of 2,4, and 6 m wide, and treatments with and without the vegetation cleared. Treatments with cleared vegetation produced high survival rates (97% vs. 86.5%), though the variation in line width did not affect survival rates. Available with subscription or purchase |
Growth of dipterocarp seedlings in artificial gaps: An experiment in a logged-over rainforest in South Kalimantan, IndonesiaBackgroundRegeneration of dipterocarps following logging has become a crucial issue in tropical forest management. Secondary forest frequently and rapidly replaces dipterocarps in large logged-over patches. If unmanaged, these secondary forest patches are often composed of unmerchantable early-succession species. It has been hypothesized that dipterocarps grow most successfully in small gaps. Available with subscription or purchase |
Plantaciones forestales con especies nativas: Una alternativa para la producción de madera y la provisión de servicios ambientales (Native species tree plantations: and alternative for wood production and environmental services)Se presenta un panorama general del desarrollo de las actividades de plantaciones forestales en Costa Rica, así como algunos resultados de ensayos de rehabilitación de áreas degradadas con especies forestales nativas en la Estación Biológica La Selva. Durante 12 años, se midió anualmente el crecimiento y la producción de biomasa aérea de doce especies nativas en rodales mixtos y puros, como asi también la fertilidad del suelo bajo plantaciones puras de cuatro especies forestales nativas. La mezcla de especies mostro la mayor productividad volumétrica, estadísticamente superior a las especies en plantaciones puras. Open access copy available |
Restoration of a Coastal Swamp Forest in Southeast BrazilbackgroundThis study evaluates the potential for nine native tree and shrub species for use in the revegetation of degraded swamps in Rio de Janeiro, Brazil. Research Goals & MethodsInvasive grasses and other vegetation, including the exotic tree Casuarina equisetifolia were removed from the site. Available with subscription or purchase |
Forest Recovery after Swidden Cultivation across a 40-year Chronosequence in the Atlantic Forest of Southern Bahia, BrazilbackgroundSecondary forest with a range of ages was compared to old growth forest in the Serra do Conduru State Park in Southern Bahia, Brazil in terms of species composition and structure.

Ecological Significance of Crown Functional Traits Across Size Classes and Disturbance Environments in Eight Pioneer Species in a Sri Lankan Rain ForestbackgroundThis article evaluates the tree crown characteristics of eight pioneer tree species in the Shorea-Mesua vegetation type (an aseasonal, mixed dipterocarp forest) around the Sinharaja World Heritage Forest Reserve in southwest Sri Lanka. Research Goals & MethodsThe crown surface area, crown volume, and live crown ratio were measured as well as evaluated for their correlation with tree size classes and disturbance causes.
