Horizontal structure analysis by Kernel density as basis to forest management i...

The present work aimed to characterize the horizontal structure of an area of primary Amazonian Forest and the spatial distribution of the species Goupia glabra (Aubl.), Qualea spp. and Dipteryx odorata (Aubl.) Willd. through the analysis of the Kernel density, aiming to support the planning of forest management. The study area is located in Santa Carmem, microregion of Sinop, state of Mato Grosso (1,024 ha), w...

Influence of plot size in Weibull's diameter distribution function precision in...

Influence of plot size in Weibull's diameter distribution function precision in a primary forest in Central Amazon. This research aimed to evaluate how the observed data of Amazonian forest can be fitted to Weibull's probabilistic function and the influence of plot size to the fitness as well. The Weibull probabilistic function is an important tool for forest management. In this study it was used 15 different p...

Climate seasonality limits leaf carbon assimilation and wood productivity in tr...

The 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...

Modeling of survival, mortality and recruitment of a forest in Central Amazon

The objective of this research was to test and to select models for description of survival, ingrowth and mortality of all species and for group of pioneer species present in a tropical rainforest in center of the Amazon. The study area is located in the Tropical Forest Experiment Station, 90 km far from the urban center of Manaus - AM, Brazil. The data came from 12 permanent 1 ha plots with annual measurements...

Floristic and diversity of natural regeneration in clearing areas in Araucaria ...

The objective of this reserach was to evaluate and compare data on floristic and natural regeneration diversity in seven clearing areas formed by the selective management of araucaria in remnants of Araucaria Forest. The indices of Shannon and Jaccard were used, respectively, to analyze the floristic diversity and to relate the similarities in each clearing area. The classification of the species into ecologica...
