Disproportionate single-species contribution to canopy-soil nutrient flux in an Amazonian rainforest
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Rainfall, throughfall and stemflow were monitored on an event basis in an undisturbed open tropical rainforest with a large number of palm trees located in the southwestern Amazon basin of Brazil. Stemflow samples were ...
Differential gene expression in Eucalyptus clones in response to nutrient deficiency
(2022-04-01)
We evaluated differential expression of genes in leaf and xylem tissues for three Eucalyptus clones in the field using Illumina sequencing, under four contrasting fertilization regimes: a control combining nitrogen (N), ...

The purpose of this work was to estimate genetic parameters and selection gain of Pinus caribaea var. hondurensis progeny trial for wood and resin production as well as correlation between them. Experiment was established ...
ALLOMETRIC MODELS TO ESTIMATE STOCKS CARBON IN THE LOWER MONTANE FORESTS IN SOUTH OF ECUADOR
(Centro Pesquisas Florestais, Ufsm, 2018-07-01)
In Ecuador, there are montane forests of great biological importance that provide ecosystem services such as carbon storage. For this reason, we did this research for generate allometric models through by quantifying carbon ...
Genetic parameters and genotype x environment interaction in Pinus taeda clonal tests
(Elsevier B.V., 2020-10-15)
Pinus taeda (loblolly pine) is a widely-cultivated conifer that is particularly prevalent in the southeast United States and Southern Brazil. Some companies in Brazil are working with the third generation of improvement ...
Vertical optical scanning with panoramic vision for tree trunk reconstruction
(2017-12-02)
This paper presents a practical application of a technique that uses a vertical optical flow with a fisheye camera to generate dense point clouds from a single planimetric station. Accurate data can be extracted to enable ...
