Dynamics of the diameter distribution of Pinus taeda stands, in the region of Caçador, SC, Brazil PFB - Pesquisa Florestal Brasileira
Téo, Saulo Jorge; Rocha, Samara Pozzan da; Bortoncello, Aline Cristina; Paz, Rafaela Antunes; Costa, Reinaldo Hoinacki da.
The objective of this work was to fit the probability density functions Normal and SB, to describe the changes, with age, in the diameter distribution of loblolly pine (Pinus taeda) stands, in the region of Caçador, Santa Catarina State, Brazil. The data came from permanent and temporary plots, with ages ranging from 5 to 11,9, grouped in age classes with intervals of 1 year. The probability density functions were fitted and, the Kolmogorov-Smirnov test and the parameters of skewness and kurtosis were calculated. Basing on Kolmogorov-Smirnov test it was verified that, for ages from 5 to 7.9 years old, the Normal and SB functions didn’t show satisfactory adherence. The SB and Normal functions showed better adherence to the ages from 8 to 9.9 and from 10 to...

Growth and phytosociology of a forest with Colophospermum mopane in Mabalane, Gaza Province, Mozambique PFB - Pesquisa Florestal Brasileira
Bila, Jacob Miguel; Mabjaia, Nazaré.
This study aimed to characterize the composition and structure of mopane forest ecosystems, estimating growth rates and  determining the diameter distribution. It was used data from permanent plots established in 2002 in Mabalane region, Gaza Province. It was analyzed the species composition . It was also determined the horizontal structure of the forest (abundance, dominance, frequency and importance value index) and the annual periodic increment in diameter. The results showed that 15 tree species belonging to eleven botanical families occur in this region. The forest is dominated by Colophospermum mopane (Benth.) J. Léonard (mopane), with an abundance of 258.80 trees per hectare, which represents 85.8% of all individuals. The periodic annual increment...
