Mammals stand out among the main game animals of the world, being exploited by human beings for different ends, and being important for the subsistence of several communities. In semiarid environments, as in the Brazilian Caatinga biome, wild mammals have been exploited by the local human population, including endangered species. In this scenario, beyond biological research of the exploited animals, ethnozoological studies are important for supporting plans for the sustainable management and conservation strategies for the mammalian fauna of the semiarid landscape. This study aims to contribute to new research into the ethnomammalogy of this specific region. It provides a catalogue of the mammals and their ethnozoological importance, including a brief characterization of game mammals of the morphoclimatic domain of the Caatinga. The results show that at least 41 species of wild mammals interact with the population that lives in the semiarid region, as sources of products that can be used for the following purposes: food (31 species), medicinal (38 species), ornamental or decorative purposes (23 species), in magical/religious practices (31 species), and as pets (24 species). Twenty-five species are hunted because of concerns over personal safety or predation on livestock and pests. Among the recorded mammals, 13 (31.7%) are listed in some threatened category (Critically endangered, Endangered or Vulnerable). Hunting is one of the main factors contributing to this situation, which provides evidence that conservation strategies should consider the associated human needs, integrating cultural aspects of the local populations, and ecological aspects associated with the biodiversity of the region.

Ingredients derived from wild mammals are widely used in traditional remedies. Large datasets of traits, geographic ranges, and phylogeny are also available for mammals. Therefore, mammals are an ideal group in which to explore the ecological (e.g. range size, body mass) and evolutionary (i.e. shared ancestry) correlates of the use of animal‐derived products in traditional medicine. In a global analysis of correlates of the use of wild mammals in traditional medicine, we tested how life‐history traits relate to the use of mammal products to treat disease. We compiled data from the primary literature about folk remedies based on mammals via a literature search using ISI Web of Knowledge, Scopus, and Google Scholar. Then, we used modern phylogenetic comparative methods to estimate phylogenetic signals in the diseases that mammal body parts are used to treat and to test whether geographic range size and body mass are related to medicinal use. We tested whether mammalian species that are used more in medicine are also those that are more threatened by extinction. Our results show that 521 mammalian species are used to source products to treat 371 ailments. We found support for the hypothesis that phylogenetic relatedness correlates with the use of mammal‐derived remedies in traditional medicines. Specifically, we confirm our hypotheses that closely related species are more similar in terms of their perceived medical versatility than distantly related species and are used to treat similar diseases. Furthermore, we demonstrated that large marsupials are more versatile and are used to treat more diseases than smaller marsupials. In our database, 155 mammalian species are considered threatened (Vulnerable, Endangered, or Critically Endangered), and a further 46 are Near Threatened, suggesting that overexploitation for medicinal use could be an overlooked source of threat that should be considered in mammal species conservation assessments. We demonstrate that phylogenetic relatedness correlates with the use of mammalian species as remedies in traditional medicine, and urge future researchers to evaluate the negative effects of overexploitation of mammals for medical purposes. Such overexploitation could cause non‐random extinction patterns in the mammalian tree of life.

Background: In addition to playing a key role in the dynamics of ecosystems, animal diversity, especially that of wild vertebrates, is intimately linked with human evolutionary history, which has resulted in diverse interactions that must be emphasized in formal education processes. We analyzed several methods of approaches used for biological education in order to teach about wild vertebrates and their conservation in urban and rural schools in the semi-arid region of Brazil. Methods: Data were obtained via questionnaires applied to 990 students, of which 528 were urban and 462 rural, distributed among the seven grades/years that comprise the last two cycles of basic education in Brazil. The richness and diversity of the animals cited by the students were calculated, being the diversity using an adaptation of the equation for the Shannon-Weaver Index (H′). Data were analyzed using non-parametric descriptive statistics. Results: Mammals and birds had the greatest richness and diversity of animals cited as most-studied in science/biology classes, and also the most indicated as occurring in the studied region. Among mammals, large carnivores with a showy appearance and utilitarian value had the highest citation frequencies, while there was a tendency for limited recognition of faunistic diversity in the other groups mentioned. Almost 70% of the students stated that their schooling processes dealt with the conservation of wild animals; however, about 50% of the students in both urban and rural contexts did not express conceptual understanding about the conservation of nature. Conclusions: The recognition of animal diversity, especially vertebrates, beyond just mammals and birds, as well as conceptual clarity about the conservation of nature, are fundamental factors for the development of critical awareness of fauna and its conservation, and where the processes of schooling have a preponderant role. Finally, the study contributes to the legitimization of Ethnobiology as an interdisciplinary field of knowledge, especially in its interface with education, in addition to pointing out the importance of optimizing efforts in approaches to biodiversity conservation in formal educational processes.

A caatinga brasileira é uma das florestas tropicais secas mais ameaçadas do mundo, principalmente devido á fragmentação de habitats em função das pressões antrópicas. No entanto, as regiões montanhosas da Caatinga são consideradas refúgios de biodiversidade, com elevada riqueza de espécies vegetais, as quais são utilizadas para diversas finalidades por populações humanas locais. O presente estudo buscou identificar o conhecimento ecológico local das comunidades rurais no entorno de uma Serra na região semi-árida do Brasil, considerada um refúgio para a biodiversidade. O estudo foi realizado por meio de entrevistas semiestruturadas, com informantes-chave sendo selecionados pela técnica de amostragem de bola de neve. Segundo os informantes, a serra representa o resgate na memória de paisagens anteriores, ligadas à biodiversidade que ela contém e explicando a importância como fonte de recursos e influência nos regimes locais de chuvas. Para as populações locais, a conservação da biodiversidade da Caatinga representa mais do que apenas a preservação da fauna e flora, compreendendo também a permanência das funções dos ecossistemas para a manutenção de suas atividades.

Recognition of the diversity of living beings, including the classification and naming of species, is a fundamental condition for biological literacy with the aim of developing critical awareness of human relationships with nature, and for which formal education plays an important role. The present study aimed to analyze the representation that urban/rural students have for wild vertebrates and their main sources of knowledge. Data collection took place in three public schools, one urban and two rural, in the municipality of Campina Grande, Paraíba, Brazil. Questionnaires were given to 990 students (528 urban and 462 rural), distributed among all the grades that comprise middle school (Ensino Fundamental II, grades 6–9) and high school (Ensino Médio, grades 10–12) education. A total of 5877 citations were mentioned by the students, which corresponded to 224 distinct animals with 166 (72.0%) being wild vertebrates, 24 (25.7%) being domestic vertebrates, and 34 (2.3%) being invertebrates. Mammals and reptiles had the greatest observed richness of citations, while mammals (H′ = 3.37), birds (H′ = 2.84), and invertebrates (H′ = 2.94) had the greatest diversity. Positive correlations were found between citations of wild vertebrates and family income (rt = 0.06; P < 0.05) and curricular development (rs = 0.08; P < 0.01); negative correlations were found between curricular development and citations of domestic animals (rs = − 0.22; rs = − 0.11 P < 0.01) and between age group and citations of invertebrates (r = − 0.14; rs = − 0.11 P < 0.01). As for the sources of knowledge regarding the animals indicated by the students, “media,” “daily experiences,” “tradition” (here understood as knowledge resulting from interactions with parents and experienced community members), and “formal education” stood out. Comprehension of vertebrate diversity is a fundamental condition for the development of attitudes compatible with its conservation, which emphasizes the importance of biological literacy in achieving this purpose.

Hunting wildlife for medicinal purposes is a widespread practice throughout Brazil; however, studies about the animals used for zootherapeutic practices have been performed almost exclusively with traders (herbalists) and end consumers, and not hunters. This makes it difficult to completely understand the market chain, trade strategies, and drivers of this practice. The present study investigated the species hunted or trapped for traditional medicinal uses by collecting data about the use and trade of the zootheurapeutic species. We collected data through semi-structured questionnaires complemented by free interviews and informal conversations with hunters in five municipalities of semiarid region of the NE Brazil. We calculated the Use-Value (UV) index to determine the relative importance of each species reported by interviewees. The Multiple Linear Regression model was used to assess the influence of socioeconomic factors (age, schooling, residence zone, trade of zootherapeutic species) on species richness exploited by hunters. Hunters reported a significant richness of species (n = 39) intentionally or opportunistically captured for use as remedies for treatment of 92 diseases or conditions in humans or livestock. Respondents also reported trade strategies that were well-organized and quickly directed the selling of wild animals or byproducts via modern technology. We found a weak positive relationship only between species richness and hunters’ age via MLR model. The hunting and use of wild species for medicinal purposes are culturally disseminated activities among hunters. Our results demonstrate the importance of studying hunters in order to understanding the dynamics of bushmeat exploitation and to develop more efficient strategies for wildlife use and conservation.
