CROWN MORPHOMETRY FOR TWO VALUABLE TIMBER SPECIES FROM MIOMBO WOODLAND IN MOZAM...
Hofiço, Noé dos Santos Ananias; Costa, Emanuel Arnoni; Fleig , Frederico Dimas; Finger, César Augusto GuimarãesPterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. & Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter in studies of the growth of individual trees. In this sense, the present study aimed to study the morphometric relationships of P. angolensis and B. madagascariensis a...
Climate seasonality limits leaf carbon assimilation and wood productivity in tr...
Wagner, Fabien H.; Hérault, Bruno; Bonal, Damien; Stahl, Clément; Anderson, Liana Oighenstein; Baker, Timothy R.; Sebastian Becker, GabrielThe seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy p...
Basal area increment model of araucaria trees in uneven aged forest
Costa, Emanuel Arnoni; Finger, César Augusto Guimarães; Hess, André FelipeThe present study aimed to develop a mathematical model to describe annual periodic percentage increment in basal area of Araucaria angustifolia trees with data collected from increment cores extracted radially from the trunk at breast height of 109 trees distributed in a large diameter range. Dendrometric and morphometric attributes were tested by multiple linear regressions as independent variables and their ...
Characterization and vegetation dynamics of the Savana Estepica Parque, Barra d...
Watzlawick, Luciano Farinha; Longhi, Solon Jonas; Schneider, Paulo Renato; Finger, César Augusto Guimarães; Longhi, Regis VillanovaThis research was carried out at Parque Estadual do Espinilho, in Barra do Quaraí, Rio Grande do Sul State, Brazil, aiming to characterize the floristic, phytosociological structure and dynamics in Savana Estépica Parque. For such, within a permanent sample unit of 1 ha (100 m x 100 m), were identified and measured all individuals with diameter at breast height (DBH) ≥ 10 cm. The floristic is made up of Prosopi...
