| The natural regeneration after natural or anthropogenic disturbances is an important element to reestablishing shrubby-arboreal species, that is, in the restoration of abundance. To the analysis of the floristic composition and some phytosociology parameters of one three years old clearing that was burned in a mixed ambrofila forest near Segredo, RS, was sampled 16 parts measuring 2m x 2m, totaling 64 m². Was found 240 individuals belonging to 42 shrubby-arboreal species. Therefore naturally trough processes of regeneration, the environment is covering himself, showing notable abundance. The species diversification may be contributing to the formation of different ecological guilds, which will facilitate in a time range, the gradual restoration of the... |

| ABSTRACT This study aimed to analyze the evolution of Brazilian wood doors exports in the period 2005-2015, as to their concentration. Monetary values of exports were collected in the UNCONTRADE database and deflated (base year 2005). For determine the concentration, it used the methods of Herfindahl-Hirschman and the concentration ratio (CR2, CR4 and CR8) classified in the Bain criteria. The real value of Brazilian exports ports for the reporting period decreased from US $ 227.3 million in 2005 to US $ 154.3 million in 2015. The analysis of the concentration of Brazilian exports doors, by Hirschman Index -Herfindahl the period 2005-2009, showed a fall of market concentration ranging from 0.4626 to 0.2829 in the meantime. According to the criterion of... |
