Characteristics and properties of torrefied biomass pellets from Gmelina arborea and Dipterix panamensis at different times
(Revista Chapingo, Serie Ciencias Forestales y del Ambiente, 2016)
Torrefaction and pelletizing were studied in the generation of energy from
lignocellulosic residues to increase the energy properties of the biomass. The aim of
this study was torrefied sawdust from Gmelina arborea and ...
Reducing warp and checking in 4 by 4 beams from small-diameter tropical species (tectona grandis, gmelina arborea, and cordia alliodora) obtained by turning the pith inside out.
(Forest Products Society, 2015)
Small-diameter logs from plantation trees are prone to warp and to produce checks due to the presence of juvenile wood, growth stresses, and asymmetric shrinkage during the drying process. In the present study, we analyzed ...

Evaluation of biodeterioration and the dynamic modulus of elasticity of wood in ten fast-growing tropical species in costa rica exposed to field testing
(Statny Drevarsky Vyskumny Ustav, 2015)
In tropical regions, it is possible to produce a large variety of timber species in plantation conditions. However, wood from these trees has low natural durability. Biodeterioration and the dynamic modulus of elasticity ...
Guidelines for documenting and reporting tree allometric equations
(Springer-Verlag France, 2015-09)
Given the pressing need to quantify carbon fluxes associated with terrestrial vegetation dynamics, an increasing number of researchers have sought to improve estimates of tree volume, biomass, and carbon stocks. Tree ...
Production and quality analysis of pellets manufactured from five potential energy crops in the Northern Region of Costa Rica
(Biomass and Bioenergy, 2016)
Modifications to a pellet manufacturing process must be made based on the characteristics of raw
material used. The purpose of this work was to determine the alternations required to a wood pellet
manufacturing process ...
Mineral content in relation to radial position, altitude, chemical properties and density of persian ironwood
(Universidade Federal de Sao Carlos, 2015)
Persian ironwood (Parrotia persica) is native species from Iran and covers 10,54% of the commercial volume. Its wood structure and its chemical composition are affected by growth conditions. The aim of the study was to ...
Current perspectives on forest recovery trends in Guanacaste, Costa Rica
(International Forestry Review, 2019)
The main goal of this study was to evaluate whether the trends in the recovery of forest cover in Guanacaste continued during the past decade
and to evaluate if the socioeconomic drivers of recovery have been altered. Our ...
Population status of the tree Sacoglottis holdridgei (Humiriaceae) at Isla del Coco National Park, Costa Rica
(Revista de Biología Tropical, 2016)
Isla del Coco is the only oceanic island in the Eastern Pacific with humid tropical climate. Its forests
have a particular structure with a unique array of plant species and high endemism. There are few studies on
the ...
Tree species composition, breeding systems, and pollination and dispersal syndromes in three forest successional stages in a tropical dry forest in Mesoamerica
(Mongaby.com e-journal, 2015)
Tropical dry forests (TDF) in Mesoamerica are highly endangered by the expansion of human activities (e.g., agriculture and cattle ranching). In contrast, TDF in Costa Rica have experienced outstanding restoration due to ...
