Resumo: |
The goal of this study was to evaluate the population structure of Lonchocarpus cultratus located in a riparian zone in the flood plain of the upper Paraná River. Data were collected on the stem diameter at breast height (DBH) and the plant height from two phytosociological inventories, which were performed with a 14-year interval, using data collected in studies conducted in 1992 and 2006 in an Atlantic Forest riparian zone remnant of Paraná State, Brazil. Class intervals for DBH and plant height were defined using the Spiegel equation, and the measured values were distributed between the different distinct classes. The distribution of individuals between the different DBH classes was analyzed using de Liocourt’s quotient (q). For both stages of the study, the DBH distribution resulted in an inverted-J curve, as expected for uneven-aged forests. The distribution of the height values was irregular, as expected for an early succession species. The de Liocourt q indicated an unbalanced distribution for both stages. However, there was a tendency towards balance in the second stage. The results imply that the studied population was maturing and maintaining its self-regenerating capacity while tending towards balance and presenting behavior characteristic of early succession species.
