Zusammenfassung
Edge effects on germination, seedling establishment, and the population structure of Parkia pendula were studied in a fragment of northeastern Brazilian Atlantic Forest. Germination and seedling survival were observed underneath adult trees in the edge zone and in the forest interior; the population structure was examined in plots with a total area of 1 ha in each environment. The overall germination rate was very low but significantly higher in the forest interior than in the edge zone (0.52% vs. 0.21%). Furthermore, the seedlings’ survival time was significantly longer in the forest interior. The probability to survive the first nine months after germination was three times higher in the forest interior. The higher germination rate and the better seedling establishment in the forest interior seem to be the reasons for the significantly higher seedling density within the forest interior. However, the patterns of saplings and juvenile trees differed from the seedling pattern. The sapling density was similar in both environments, but the density of juvenile trees was three times higher in the edge zone. Seedling density is therefore an improper prediction for the pattern of later size-classes.
