Individuals at different development stages can be influenced differently by abiotic and biotic factors because they are temporally separated.

This may cause changes in spatial patterns in ontogenetic stages. The objectives of this study were to verify the pattern of spatial distribution of saplings and adults in Dalbergia cearensis Ducke and relate it to the pattern of seed dispersal. In two areas of 4.0 ha each, located in a Private Natural Heritage Reserve (RPPN) “Não Me Deixes”, there were counted all saplings and adults.
This data were applied to the spatial analysis by distance indices, using the software Sadie Shell, version 8.0. The aggregation index (Ia) of adults was significant for both areas and showed aggregated distribution.
Cearensis saplings showed an aggregated distribution in the area I and area II. The dispersion distance was proportional for both areas, and the highest proportion of seeds was 10 - 20 m away from the center of the aggregation.

The purpose of this study was to survey the Angiosperms from an area of Caatinga, in the Grota do Angico Natural Monument, state of Sergipe, Brazil. A total of 174 species and 51 families were registered. Fabaceae (29 species) is the family with the highest number of species, followed by Asteraceae (11), Euphorbiaceae (10), Malvaceae and Poaceae (9 each) and Rubiaceae (8), Bromeliaceae, Cactaceae and Convolvulaceae (7 each). Most species are herbaceous (55.2%), followed by trees (20.7%), shrubs and vines (7.5% each), subshrubs (6.3%), epiphytes (1.7%) and hemiparasites (1.2%). Approximately 17% (30 species) of the flora are endemic to the Caatinga, one species is rare and two are vulnerable.
Our results reinforce the importance of conserving the remaining forest vegetation against the anthropic pressure. That 70s Show S Episodes here.
