“…However, over the years in the applications of this index in other studies, there were limitations in its use, mainly because it did not differentiate current use from potential use citations (Albuquerque & Lucena 2005, La Torre-Cuadro & Islebe 2003, Lucena et al 2007, Stagegaard et al 2002. In this sense, Lucena et al (2012a) tested and suggested calculating the use value separately, stating that the separation interferes in ecological apparency's results.…”

The ecological apparency hypothesis seeks to understand the dynamics of use that a particular species has through its availability in vegetation areas. According to this hypothesis, apparent plants are the most collected and used by humans. This hypothesis was tested in the rural community of Santa Rita, municipality of Congo, in Cariri microregion (Paraíba state, Northeast Brazil). We calculated the use value (UV) for each species. For the phytosociological inventory, we adopted the point-quadrant method, plotting 500 points distributed in the vegetation areas of the community, registering the perimeter measurements and height of 2000 plants. Interviews were conducted with householders, totaling 98 informants (41 men and 57 women), and 24 species, 21 genera, and 11 families were recorded. The cited species were grouped into 11 utility categories. The Spearman correlation coefficient was used to correlate phytosociological and ethnobotanical data. The use values of the species did not correlate with phytosociological parameters. Regarding the use categories, there were positive correlations for fuel (UV with dominance and basal area), construction (UV with all phytosociological parameters), fodder (UV with all parameters), and poison/abortion categories (UV with density and frequency). Ecological apparency significantly explained the local importance of useful plants in fuel, construction, and fodder categories, and less significantly for poison/abortion.

“…The limitations of the UV have been documented in the literature (La Torre-Cuadros & Islebe 2003, Lucena et al 2012a, Stagegaard et al 2002. However, UV is an objective index for analysis of useful species importance in traditional populations.…”

“…Gentry (1993a, 1993b), in order to test ecological apparency, proposed in their study a quantitative index, the use value (UV), which is used to evaluate the relative importance of plant resources used by traditional populations based on uses cited by the informant. This index has been adopted and tested in subsequent studies ( Lucena et al 2007, 2012a, Stagegaard et al 2002 observed a deficiency in this index: the fact that it does not distinguish between citations of current use and potential use. This limitation could result in interference in the final considerations of the research, with the main focus being on the conservation of plant species.…”

The present study tested the ecological apparency hypothesis in a Brazilian rural community. It used the use value to test the information gained through three types of calculations (UV change , UV general , UV potential ). A vegetation inventory was performed in two areas near Capivara, Paraí-ba, Brazil, and 112 informants were interviewed. For the hypothesis test, the Spearman correlation coefficient was used to correlate the phytosociological (vegetation) and ethnobotanical data (use value). The study recorded 25 useful species in the first site and 20 in the second site. Positive correlations were found in the first site, between the UV g to basal area and dominance, and between the UV c and basal area, dominance, and importance value. In the second site, between the UV g and both basal area and dominance and between UV c and basal area, density, and dominance. Apparency explained the local importance of useful plants in construction, technology, and fuel, but was not explanative of medicine. Also, important responses were observed for the different use values.

Background: Previous studies of Maytenus macrocarpa "Chuchuhuasi" and linked species have corroborated their biological effects related to cardiovascular, respiratory, and others systems. This research has focused on evaluating the effect in the corporeal temperature, respiratory rate, heart rate and electrocardiogram of concomitant administration of "Chuchuhuasi" and propranolol in escalating doses. Methods: Albino rats were divided randomly into four control groups and five experimental groups. Temperature was measured by a digital thermometer, respiratory rate by direct-counting and electrocardiogram and heart rate by a Grass Polygraph. Rhythmic and arrhythmic electrocardiographic patterns were identified by a mathematical modeling of autocorrelation. The outcomes were acquired in periods of time but were analyzed using the average of the whole of the experiment. The result was applied to the following statistical tests: one-way ANOVA, Tuckey, Shapiro-Wilk, Pearson Correlation and Chi square with Yate's correction test. Results: The comparison between control and experimental groups showed a profile of raise in the corporeal temperature, then, for the respiratory rate the bias was to increase, in contrast, it was showed trend to decrease of the heart rate and an increase of voltages of p and r wave, also, an increment of p-r interval and presences of arrhythmias. Conclusion: This study revealed effects of concomitant administration of propranolol and Maytenus macrocarpa on temperature, respiratory rate, heart rate and electrocardiogram. In addition, it showed abnormalities in the electrocardiogram which were associated with arrhythmia patterns Thus, the usage of propranolol and Maytenus macrocarpa may negatively impact several aspects of the health of users of these drugs.
