1. Stem growth of multipurpose tree species: net effect of micrometeorological variability assessed by principal component regression
RESUMO Em um ano típico na Amazônia central, há uma estação seca amena, mas seu efeito sobre o crescimento do tronco de espécies de uso múltiplo ainda é pouco conhecido. Este estudo teve como objetivo determinar o efeito individual de variáveis microclimáticas sobre crescimento do tronco após remover a influência da intercorrelação entre os fat

2. Skin-to-skin contact and deaths in newborns weighing up to 1800 grams: a cohort study
Abstract Objective: To evaluate the association between dose of skin-to-skin contact (SSC) per day and initiation time with the occurrence of deaths in newborns with weight up to 1800g. Method: Multicentric cohort in five Brazilian neonatal units, including newborns with a birth weight of ≤1800g. The time of SSC was registered in individual file, by the

3. FITTING AND CALIBRATING A MIXED-EFFECTS SEGMENTED TAPER MODEL FOR BRUTIAN PINE
ABSTRACT Taper models are one of several necessary tools in modern forest inventory, giving information on diameter at any point along the tree stem and this information can also be used to estimate stem volume. In this study, we used nonlinear mixed-effects (NLME) modeling approach to minimize existing statistical problems in constructing taper equations. A

4. ACCURACY OF GENETIC PARAMETERS ESTIMATION AND PREDICTION OF GENOTYPIC VALUES IN EUCALYPTUS USING DIFFERENT PLOT TYPES
ABSTRACT A suitable experimental design should control the environmental effect and be capable of discriminating genotypes. Two clonal tests of Eucalyptus were planted side by side in a randomized block design with the same 32 treatments under two different plot designs. The first trial was designed with five plants per plot (linear plot, LP) and six block r

5. AUTOMATED INDIVIDUAL TREE DETECTION IN AMAZON TROPICAL FOREST FROM AIRBORNE LASER SCANNING DATA
ABSTRACT Light Detection and Ranging (LiDAR) derived individual tree crown attributes can potentially serve as a tool for ecology and forest dynamics studies and reduce field inventory costs. In this study, four methods of individual tree detection (ITD), Watershed, Silva et al. (2016), Dalponte and Coomes (2016), and Coomes et al. (2017), were evaluated in

6. Climatic signal in a radial growth of Canadian and Maximovich poplars in south-western Poland
ABSTRACT: The main goal set by researchers in this article was to gather knowledge on the structure of the basic biometric features of tree-rings of two species of poplars, belonging to different sections of Aegeiros – Populus xcanadensis and Tacamahaca – Populus maximowiczii, and to define and understand the correlation between weather and annual increm

7. Estimativa da oferta de biomassa florestal em povoamentos de Pinus taeda L. após intervenções culturais
Resumo Com a determinação do quanto de biomassa florestal é gerada após as intervenções culturais é possível definir as áreas passíveis de exploração. Com isso, o objetivo do trabalho foi quantificar e estimar a oferta de biomassa de Pinus taeda L. disponível após as intervenções culturais. O experimento foi realizado em reflorestamentos nos

8. Thrips species associated with varieties of the native cerrado fruit tree Hancornia speciosa
Resumo A mangabeira Hancornia speciosa Gomes (Apocynaceae) é uma planta nativa do Cerrado brasileiro, e os estudos de insetos associados a esta espécie vegetal geralmente são restritos a relatos de ocorrência em viveiro. Deste modo, é necessário avaliar quais insetos estão associados a esta espécie. Entre as espécies de insetos que atacam a cultura

9. The relationship between plant density and survival to water stress in seedlings of a legume tree
ABSTRACT Competition for soil water is one of the major processes that drive the assembly of plant communities, particularly in regions subjected to long dry seasons. The relationship between plant density and soil water competition has strong, but poorly understood, practical implications for population dynamics, restoration and conservation. We planted see

10. Genetic parameters to production characters of palm heart in half-sibs progenies of palm peach
RESUMO: A pupunheira (Bactris gasipaes) é uma palmeira produtora de palmito oriunda da Amazônia, que apresenta sustentabilidade econômica, social e ambiental. Para a obtenção de cultivares melhoradas é necessário a avaliação e seleção de genótipos com características que atendam produtores, processadores e consumidores. Assim, o objetivo deste

11. Visual symptoms and nutritional deficiencies in olive plants subjected to nutrient deprivation
ABSTRACT. As the fourth largest importer of olive oil and the fifth largest importer of olives, Brazil is one of the largest importers of olive (Olea europaea L.) products in the world. In recent decades, the introduction and growth of olive cultivars with lower chilling requirements in the south and southeast regions of Brazil have made olive production via

12. GROWTH, YIELD AND ECONOMIC ANALYSIS OF AN EUCALYPT-SOYBEAN CONSORTIUM: EFFECT OF THE DISTANCE BETWEEN TREES WITHIN THE ROW1
RESUMO Os sistemas agroflorestais (SAF) devem beneficiar todos os componentes do consórcio. O objetivo deste trabalho foi avaliar o efeito da distância entre plantas na linha de plantio sobre o crescimento e a produção do componente arbóreo e da cultura agrícola e, sobre a viabilidade econômica do consórcio. Para isso plantou-se clone de eucalipto no
