Background: The forest logging, even under good management practices, changes the structure and composition of the forest. It can be a risk for several species, with and without commercial use. Therefore, there is a need to understand the dynamics of different species to cause less impact in the forest succession after logging. Objective: This study aimed to evaluate the diameter structure, basal area, diameter increment and, the spatial distribution of trees in a native forest emphasizing on Eschweilera coriacea, before and after logging. Methods: The study was conducted at Fazenda Rio Capim, in Paragominas, state of Pará, in 108 ha of a terra firme rain forest. Data collecting occurred before (2003), and after logging (2007 and 2011) in 24 permanent plots of 0.25 ha, being 12 plots unlogged forest (T0) and the other 12, logged forest (T1). All trees with diameter at breast height equal or above 10 cm were evaluated. Results:The species E. coriacea had high importance value index in the three assessments and in the two treatments tested the diameter distribution of both tree community and the species population followed the reverse J-curve pattern. The Liocourt Quotient (q) for the tree community in T0 ranged from 2.03 to 2.07 and 1.98 to 2.05, in T1. However, for E. coriacea, the "q" ranged from 1.72 to 2.00 in T0 and from 1.80 to 2.05 in T1. The basal area of the tree community increased in T0, decreased in T1 in 2007, followed by an increase in 2011 and, the E. coriaceabasal area increased in T0 and T1 in the periods evaluated. No differences were detected between basal areas of the tree community or E. coriacea in the treatments/years. The diameter increment of E. coriacea was higher in T1, the spatial distribution of E. coriacea trees in both treatments was grouped. Logging did not cause changes in the tree community, although it favored the E. coricea growth. The special distribution of E. coriaceain both treatments were aggregated. Conclusion: The forest logging did not offer changes to the trees community according to the variables. There was no significant difference between the treatments and within them, certainly, the method of management applied to the area was adequate for that type of forest. Furthermore, the logging in T1 treatment favored the growth of E. coriaceathat were higher than in T0.

Muitos agricultores ficam alarmados com a quantidade de soja que fica na lavoura apos a colheita pelas combinadas. E comum observar-se os campos verdes apos lavrados para o plantio do trigo que se segue a colheita da soja. Sao plantas nascidas de graos que debulharam e cairam ao solo pela passagem da colheitadeira ou nascidas de graos que ficaram em vagens de baixa insercao nao colhidas pela lamina que passa acima delas ou ainda de plantas cortadas e que cairam ao solo sem serem trilhadas. Muitos sao os fatores que contribuem para que haja uma maior ou menor perda. Alguns controlaveis, outros incontrolaveis. Alguns facilmente determinaveis, como por exemplo, perdas devidas a epoca de plantio ou variedades usada. Outros de dificil determinacao, como perdas devidas a velocidade do molinete, tipo da maquina, atraso da colheita apos a maturacao, etc. Fizemos um levantamento, com a finalidade de se conhecer precisamente quanto por cento as perdas significam sobre a producao e quais as principais causas que as determinam. |
