| This study aimed to test the hypothesis that crown length affects the hypsometric relationship. We used data from diameter measured at 1.3 m above ground level (DBH) and total heights of 337 trees of Araucaria angustifolia (Bertol.) O. Kuntze from an urban remnant of Araucaria Forest with 15.24 ha, located in Curitiba, PR, Brazil. These trees were grouped into classes of crown length. Six hypsometric models were adjusted to the data for each class and for the entire data set. The best model was chosen based on the standard error of estimate in percentage, index of Schlaegel, and graphical analysis of residuals. The ranking indicated Trorey as the best model. The models identity test of Graybill applied to the Trorey model indicated that crown length... |

| The Gymnanthes klotzschiana is a pioneer tree species characteristic of the alluvial plains of the Ombrophilous Mixed Forest, extremely important for the conservation of the riparian forests. Therefore, this work aims to analyze a structure and dynamics of Gymnanthes klotzschiana in a fragment of Mixed Ombrophilous Forest. The used came from a sensos at in the years 2007,2010 and 2013, located in the Botanical Gaden Campus of the UFPR, Curitiba –PR, Brazil, with a total area of 15.2 hectares. Measurements were performed at intervals of 3 years, and all trees with diameter at breast heitght (DBH) greater than 10 cm were measured and identified. The structural analyzes were performed based on the population parameters by species as proposed by... |
