Traditional knowledge and use of mammals in a rural community in the Sertaneja depression (Paraíba State, Northeast Brazil)

94-103Mammal species are important populations of the semi-arid region of Northeast Brazil. However, these species may be over-exploited, meaning that ethno zoological studies are vital to ensure that the appropriate conservation strategies are applied. This research aimed to collect and analyze data relating to the local knowledge and use of these mammals obtained through semi-structured questionnaires. The study was carried out in the municipality of Lagoa, Paraíba State, Northeast Brazil. Data were analyzed by calculating the general, potential, and current use values. The medium use values of the species were also calculated, as well as the fidelity level of the information and the rank-order priority. Twenty-three animals were recorded, of which twenty were identified at the species level. From interviews with local people, Dasypus novemcinctus was the most cited species. However, Mazama gouazoubira was the most important in terms of current use. The uses of animals fell into four categories: food, captive breeding, zooterapic, and artisanal. Food was the most cited category, including 19 species, 16 of which at the 100% fidelity level. More in-depth studies are needed to obtain further data on the uses of species in order to develop strategies to mitigate possible local extinction and inform sustainable plans for the use of fauna resources in the region

Local knowledge, use, and conservation of wild birds in the semi-arid region of Paraíba state, northeastern Brazil

Abstract Background The use of wild birds, for several purposes, is directly associated with cultural, ecological, and conservation issues. This study aimed to inventory the wild birds known and used in three communities in Paraíba state, northeast Brazil, and to investigate the sociocultural context in which these activities occur. Methods A total of 179 people (98 women and 81 men) were interviewed. Data were collected through free interviews, using semi-structured forms, and posing questions about the use of local wild birds. The species were identified by direct observation of the birds, analysis of photographic records, and the use of a scientific guide. Results Each species’ use value (UV) was calculated in three different ways: UVgeneral, UVcurrent, and UVpotential. These UVs ranged from 0.01 to 1.15 for UVg, 0 to 0.21 for UVc, and 0.01 to 1.02 for UVp. A total of 99 species, 81 genera, and 40 families were recorded and classified into the use categories of food, breeding, and medicinal. Thraupidae (12 species), Columbidae, Accipitridae, and Icteridae (8 species each) were the most diverse families. Conclusions The use of wild birds is a widespread activity in the studied areas, where many species are used. This demonstrates the need to conduct studies to assess the pressure suffered by these bird species, as well as the need to create public policies that intervene in the use and conservation of wild birds
