Última Spatial patterns of tree community dynamics are detectable in a small (4 ha) and disturbed fragment of the Brazilian Atlantic forest Acta Botanica Machado,Evandro Luiz Mendonça; Oliveira-Filho,Ary Teixeira de. The dynamics of the tree community of a fragment of tropical semideciduous forest was investigated in south-eastern Brazil. Surveys were carried out in 2000 and 2005 in 29 20 × 20 m plots. The main purpose was to assess the possibility of detecting spatial patterns of dynamics that could be related to the heterogeneity of both the environment and disturbance history in a small forest area (4.0 ha). Rates of mortality and recruitment of trees and gain and loss of basal area were obtained for the whole sample, four pre-defined soil habitats, diameter classes and twelve tree populations. The tree community was rather unstable in the period, once mortality rates surpassed recruitment rates and loss rates of basal area surpassed gain rates all-over the area...

Acta Botanica Alves,Luciana F.; Martins,Fernando R.; Santos,Flavio A.M.. The stem allometry (stem diameter vs. tree height) of a Neotropical palm (Euterpe edulis) found in rain and seasonal forest of Southeastern Brazil was examined. Observed height-diameter relationships along the stem (diameter at ground level, (dgl), and diameter at breast height (dbh) were compared to three theoretical stability mechanical models: elastic similarity, stress similarity and geometric similarity. Slopes of log-transformed height-diameter relationships did not lie near those predicted by any stability mechanical models. Significant differences in stem allometry were found when comparing dgl to dbh, suggesting greater increase in dbh with height. The relationship between stability safety factor (SSF) and palm height showed that both dgl and dbh...

Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-33062004000200016 Tree population and community dynamics in a Brazilian tropical semideciduous forest Rev. Bras. Bot. Appolinário,Vivette; Oliveira Filho,Ary T.; Guilherme,Frederico A.G.. The dynamics of the tree community and 30 tree populations were examined in an area of tropical semideciduous forest located on the margin of the Rio Grande, SE Brazil, based on surveys done in 1990 and 1997 in three 0.18 ha plots. The main purpose was to assess whether variations in dynamics were related to topography and the effects of a catastrophic flood in 1992. Rates of mortality and recruitment of trees and gain and loss of basal area in two topographic sites, lower (flooded) and upper (non-flooded), were obtained. Projected trajectories of mean and accelerated growth in diameter were obtained for each species. In both topographic sites, mortality rates surpassed recruitment rates, gain rates of basal area surpassed loss rates, and size...

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-84042005000200014 Influência do solo e topografia sobre as variações da composição florística e estrutura da comunidade arbóreo-arbustiva de uma floresta estacional semidecidual em Ingaí, MG Rev. Bras. Bot. BOTREL,REJANE T.; OLIVEIRA FILHO,ARY T.; RODRIGUES,LUCIENE A.; CURI,NILTON. Foi realizado um levantamento da comunidade arbóreo-arbustiva, da topografia e dos solos de um fragmento de floresta estacional semidecidual com o objetivo de verificar as possíveis correlações entre variações da estrutura fisionômica e composição de espécies e variações do regime de água e fertilidade química dos solos. O fragmento florestal, com área de 17 ha, localiza-se às margens do rio Ingaí (21º24' S e 44º55' W), no município de Ingaí, MG. Foram realizados um levantamento plani-altimétrico da área e uma classificação detalhada dos solos da floresta. Foram alocadas 25 parcelas de 20 × 20 m para amostrar os indivíduos arbóreo-arbustivos com diâmetro à altura do peito (DAP) > ou = 5 cm. Amostras do solo superficial (0-20 cm de profundidade) foram...
