【 摘 要 】

This study tested the ecological apparency hypothesis in the community of Barroquinha, in the municipality of Lagoa, Paraíba State, Brazil. We used the Use Value (UV) by testing the information obtained through three types of calculations: UVgeneral, UVcurrent, and UVpotential. The botanical sampling was conducted in two areas of the community (Preserved - A1; Degraded - A2), and interviews were carried out with 66 people, who signed a Free and Transparent Consent form, required by the Research Ethics Committee. The Spearman's correlation test was performed to relate phytosociological data to ethnobotanical data. We used the Pearson Correlation to test the correlation between genders and the Use Values (UVs). Fifteen useful species were recorded in A1 and 16 species in A2. Positive correlations were found in both areas between species and the phytosociological data: in A1 between UVcurrent with basal area and dominance (p < 0.05) and in A2 between UVgeneral and UVcurrent with all parameters (p < 0.05). Only the forage category showed a positive correlation in A1 between UVpotential and density and frequency (p < 0.05). In A2, the fuel category was correlated with UVcurrent and basal area and dominance (p < 0.05). There was positive correlation between UVgeneral/UVcurrent, UVgeneral/UVpotential, UVcurrent/UVpotential (p < 0.0001). Men and women considered the same species as the most important (p < 0.0001). According to the results of this study, we can conclude that ecological apparency best explains the relationship between use and availability of species used for timber.
