Direct seeding reduces costs, but it is not promising for restoring tropical seasonal forests
Souza, Diego Cerveira de
; Engel, Vera Lex (Ecological Engineering, 2018) [Artigo]
Direct seeding is a potential technique to restore forests; however, further studies are needed before its application on a large scale. We carried out a field experiment in a deforested area in southern Brazil to test the ... -
Management of Eucalyptus short-rotation coppice and its outcome on fuel quality
Eufrade-Junior, Humberto de Jesus; Guerra, Saulo Philipe Sebastião ; Sansígolo, Cláudio Angeli ; Ballarin, Adriano Wagner (Renewable Energy, 2018) [Artigo]
Earlier experiments with young Eucalyptus short-rotation coppice (SRC) in tropical environment have not evaluated the quality of whole-tree biomass fractions, and as such their total energy potential is still unknown. As ... -

The sustainability of the system soil-forest-water involves essential variables such as soil conservation and its productive potential, the maintenance of plant’s and animal’s biodiversity, the maintenance of the hydrological ... -
Hydrophysics: Water dynamics in soil profile
Rodrigues, Valdemir Antonio; ; Rezende, Marcos Antonio ; Costa, Vladimir Eliodoro (Soil Management: Technological Systems, Practices and Ecological Implications, 2015) [Capítulo de livro]
On its different stages of growth, the vegetation shows the dynamic of the consumption of water from the soil by evapotranspiration. The remaining water is stored according to soil texture and, as time goes by, it reaches ... -
Forest Landscape Restoration: increasing the positive impacts of forest restoration or simply the area under tree cover?
; ; ; Engel, Vera Lex (Restoration Ecology, 2017) [Artigo]
Restoring forest landscapes is critical in the face of continued global forest loss and degradation. In this article, we explore some challenges underlying the delivery of global commitments to restore forest landscapes. ... -
Interceptação da precipitação pelas copas em Pinus halepensis mill - Albacete - Espanha
Rodrigues, Valdemir Antonio; ; ; ; Sánchez-Román, Rodrigo Máximo (IRRIGA, 2016) [Artigo]
Hydrological processes are essential in understanding the redistribution of water in the forest ecosystem. The objectives were to evaluate the precipitation, interceptation by canopies, the effective rainfall, water ... -
Calorific value and chemical properties in juvenile and mature wood of thermally-modified Eucalyptus grandis
Calonego, Fred Willians; Severo, Elias Taylor Durgante ; Sansígolo, Cláudio Angeli ; De Rezende, Marcos Antonio ; Bruder, Edson Marcelo ; Costa, Vladimir Eliodoro (Drvna Industrija, 2016) [Artigo]
During thermal modification, timber is exposed to temperatures approaching 200 °C for several hours and wood properties change. This study was aimed at evaluating the calorific value and chemical properties of juvenile and ... -
Quantitative analysis of uncertainty in financial risk assessment of road transportation of wood in Uruguay
Simões, Danilo; ; Batistela, Gislaine Cristina ; Souza Passos, José Raimundo de ; Fenner, Paulo Torres (Forests, 2016) [Artigo]
The uncertainty in road transportation of wood is inherent to its operational costs, to the amount of transported wood, to the traveled distance, to its revenue, and more. Although it is not possible to measure this ... -
Degradation of Riparian Forest Affects Soil Properties and Ecosystem Services Provision in Eastern Amazon of Brazil
; ; Engel, Vera Lex; ; ; ; (Land Degradation and Development, 2017) [Artigo]
Brazil's riparian forests are continuously threatened by conversion into agricultural areas, causing not only degradation and loss of vegetation but also negative changes in soil properties and ecosystem services. In order ... -
