Temporal evaluation of the Conservation Priority Index for medicinal plants Acta Botanica
Souza,André dos Santos; Albuquerque,Ulysses Paulino; Nascimento,André Luiz Borba do; Santoro,Flávia Rosa; Torres-Avilez,Wendy Marisol; Lucena,Reinaldo Farias Paiva de; Monteiro,Júlio Marcelino.
ABSTRACT We investigated, through a temporal comparison, the extraction of non-timber forest resources by quantitatively analyzing the Conservation Priority Index (CPI). The study focused on the Fulni-ô Indigenous Territory, in the municipality of Águas Belas, PE (Northeast Brazil), which is characterized by caatinga vegetation (seasonal dry forest). Information on the availability of the exploited resources and the reported use of the species were obtained from vegetation sampling and semi-structured interviews, respectively. Our results demonstrated a reduction in species richness overtime, which may be due to continued resource extraction in the area, and that some species with low densities were even more affected. The species reported as being at high...

What matters in free listing? A probabilistic interpretation of the salience index Acta Botanica
Chaves,Leonardo da Silva; Nascimento,André Luiz Borba do; Albuquerque,Ulysses Paulino.
ABSTRACT Free listing is a data collection technique used in different subject areas to characterize a given cultural domain. Analysis of a set of lists from a human population allows inferences to be made about the cultural salience of the items in that domain. However, the challenge that the salience index presents is establishing a threshold value for determining whether an item can be considered salient or not. The present analysis reveals how to determine which items of a list have non-randomly determined citation frequency and order. Monte Carlo techniques were used to create a hypothetical null scenario. The present analysis not only objectively identifies which items stand out in relation to the others, it also reveals which items can be considered...
