E-mails: [email protected]; [email protected]; [email protected] Received 04.06.10; revised 13.04.11 The present study, undertaken in a traditional community in the semiarid region of Paraíba State, registered the principal animal species hunted for nutritional purposes or because they are considered dangerous to people and/or their domestic animals or cause other economic damage (in what can be called control-hunting), and evaluated the implications of these practices in terms of the conservation of the local fauna. The interviewees cited a total of 38 species of wild animals that were hunted in the region for food or that represented (in the opinion of the interviewees) some risk to humans and/or domestic stocks. The species cited could be grouped into 6 faunal groups (mammals, birds, reptiles, amphibians, fish, and arthropods). Subsistence hunting in the study region is principally directed towards birds and mammals, which represent alternative sources of protein for local human populations. Hunting for pest control is principally directed towards reptiles (which are considered dangerous or loathsome) and these animals are indiscriminately killed whether they are poisonous or not. Keywords: Hunting, Subsistence, Wildlife conservation IPC Int. Cl.8 : A01; A01K The many different uses for faunal resources made hunting one of the most ancient practices linked to human survival1,2, and even though hunting is illegal in Brazil (Federal Law Nº 5.197, 1967) numerous species continued to be taken in every part of the country2-5. Many animal species in the semiarid region (Caatinga biome) of Brazil are threatened with extinction due to intense hunting pressure and degradation of their habitats 6,7. Few ethnozoological studies have examined hunting activities in the region1, however, and relatively little attention has been given to this aspect of human interactions with that nation’s biodiversity - even though these activities represent one of the principal threats to the local faunal 8. The persistence of illegal hunting activities in the semiarid region is largely driven by survival considerations in light of the nutritional importance of wild animals 9 as a source of protein for human populations 10-14. Additionally, animals are widely used for medicinal, magical/religious, cosmetic, —————— * Corresponding author ornamental, and handicraft purposes and some are kept as pets1. Another factor that stimulates the killing of wild animals in Brazilian biomes is their potential for attacking humans or domestic stocks1,15. The present study, undertaken in a traditional community in the semiarid region of Paraíba State, registered the principal animal species hunted for nutritional purposes or because they are considered dangerous to people and/or their domestic animals or cause other economic damage (in what can be called control-hunting), and evaluated the implications of these practices in terms of the conservation of the local fauna. Methodology The present work was undertaken between August and December 2008 in the community of Sítio Gravatá in the municipality of Queimadas (7º21´29" S x 35º53´53" W), Paraíba State, Northeastern Brazil. The municipality of Queimadas covers an area of 409 km². The municipal seat is located 117 km from the state capital17,18 at an altitude of approximately 450 m. The municipality was created in 1961 and has a total population of 38,883, with approximately BARBOSA et al. : HUNTING PRACTICES IN THE SEMIARID REGION 19,000 people living in rural areas18. The population of the municipality of Queimadas is composed largely of Sertanejos who are the descendents of families originally from the Agreste (dry forest) meso-region of Paraíba State. The community in which the research was carried out has approximately 80 residences, and is located near some low mountains with remnants of intact native vegetation. Procedures and data analysis The first phase of the research involved interviewing local inhabitants who hunted animals for food or because they threatened humans or domestic animals. After initial contacts, detailed information about hunting practices were obtained through the application of semi-structured questionaires19,20 complemented with unstructured individual interviews 20-22. The semi-structured questionnaires contained questions concerning the nature of the animals that were hunted, how these animals were captured, and the principal motivations for hunting. The common names of the species cited were noted as mentioned by the interviewees, and the animal were later identified by: 1) analyses of the specimens donated by the interviewees; 2) analyses of photographs of the animals made during the interviews; 3) correlating their common names, with the aid of taxonomists familiar with the fauna in the study area 24. For each species of animal cited we calculated their respective use-values “UV” (adapted25), which measure the relative importance (or danger) of the locally known species (independent of the personal opinion of the researcher). The use-values were calculated using the following formula: (UV = ΣU/n), where: UV = use-value of the species; U = number of citations per species; n = number of informants. Results and discussion Forty-six people were interviewed (28 women and 18 men) between the ages of 17 and 78. The interviewees cited a total of 38 species of wild animals that were hunted in the region for food or that represented (in the opinion of the interviewees) some risk to humans and/or domestic stocks. The species cited could be grouped into six faunal groups (mammals, birds, reptiles, amphibians, fish, and arthropods) (Fig. 1). According to the interviewees, birds were the most intensively hunted animal group (for food) 487 (n=8 citations), and in the case of hunting for pest control, reptiles (n=10) were more intensively targeted; three species were hunted for both reasons: honey bees - Apis mellifera; the “Teju” lizard - Tupinambis merianae; and the “Timbu” armadillo - Didelphis albiventris. Table 1 lists the animal species and the number of citations for each within the different hunting categories as well as their local use-values (UV); Fig. 2 demonstrates the different animal groups according to the motives cited for hunting them. The use-values (UV) of the species cited varied from 0.043 to 0.630. Most of the species had low use-values (less than 0.25), although 5 species had UVs greater than 0.40, (the “Rolinha cambuta” dove - Columbina minuta, UV = 0.630; the “Preá” rodent - Cavia aperea, UV = 0.413; “Timbu” armadillo - Didelphis albiventris, UV = 0.413; cockroaches - Periplaneta americana, UV = 0.413; and “Tanajura” ants - Atta cephalotes, UV = 0.413) reflecting significant efforts directed towards killing these animals in the research area. According to interviewees, some of the animals that are hunted for food can be kept in captivity in order to fatten them for later consumption or sale. The animals kept for these purposes are: the “Peba” Fig. 1—Distribution of the faunal groups cited as being hunted near the study locality Fig. 2—Distribution of the animal groups according to the motives cited for hunting them in the Gravatá community, Paraíba State, Brazil 488 INDIAN J TRADITIONAL KNOWLEDGE VOL 10, No. 3, JULY 2011 Table 1—Animals hunted by the Sítio Gravatá community: Identification, motivation for hunting them, total numbers of citations, and their use-values (UV) Taxonomic group/Family/Vernacular name/Species Subsistence Control Citations VU 9 9 10 11 11 19 3 9 19 0.196 0.217 0.239 0.239 0.413 0.065 0.196 0.413 4 4 3 11 6 2 13 11 4 18 29 0.087 0.087 0.065 0.239 0.130 0.043 0.283 0.239 0.087 0.391 0.630 3 14 3 13 11 8 5 9 13 6 12 11 0.065 0.304 0.065 0.283 0.239 0.174 0.109 0.196 0.283 0.130 0.261 0.239 Mammals Furão - Mustela putorius furo, Linnaeus, 1758 Mocó - Kerodon rupestris (Wied-Neuwied, 1820) Morcego - Molossus molossus, (Pallas, 1766) Peba - Euphractus sexcinctus, (Linnaeus, 1758) Preá - Cavia aperea Erxleben, 1777 Tacaca - Conepatus semistriatus (Boddaert, 1785) Tatu - Dasypus novemcinctus, (Linnaeus, 1758) Timbu - Didelphis albiventris (Lund, 1840) Birds Burguesa Branca – Streptopelia sp.

Other hunting techniques mentioned by the interviewees included using sling-shots, ambushing (“espera”, waiting for the animals to appear at feeding spots or watering holes), and calling (“arremedo”, using bird calls to attract them within killing range). All of the hunting techniques cited in the present work were observed during an earlier study of the hunting strategies used in the semiarid region of Paraiba State1, which suggests the wide dissemination of these methods throughout the region. A similar study of hunting practices in a rural colony in the Amazonian region of Mato Grosso State 5 likewise reported the use of some of these same techniques. The capture of wild animals contributes both directly and indirectly to the subsistence of human communities throughout the world 26. Subsistence hunting in the community studied here was directly largely towards birds and mammals. According to the interviewees, these two animal groups are highly valued due to two main factors: the relative abundance of these animals in comparison to other groups of vertebrates; and their medium to large size (which implies more protein content). A greater synergetic potential of mammals and birds has been reported by a number of authors 26-30. Trinca & Ferrari 5 undertook a study of hunting in Mato-Grosso State, Brazil, and noted that the choice of the animals most frequently taken was related to both their local abundance and their sizes. Studies examining the use of the wild fauna by a community established adjacent to a biological reserve in Campeche (southeastern Mexico 31) also noted that mammals and birds were the principal focus of subsistence hunting. The link between humans and animals is fraught with contradictions and ambiguities, as the native fauna can represent either a resource or a risk to the local people32. This affirmation is corroborated by the community studied here, where the possibility of some elements of the local fauna attacking humans (or their domestic animals) motivates the killing of a number of different species. A similar situation was observed in a hunting study undertaken in a rural community in Japuranã, in the municipality of Nova Bandeirantes, Mato Grosso State5, where it was determined that 14.2% of the hunting episodes were motivated by the fact that the animals were considered predators of domestic stock or dangerous to both domestic animals and people. It should be pointed out that most carnivorous predators do not normally attack domestic animals as their natural environment provides 489 them with sufficient game to survive, and they largely tend to avoid any contact with humans or their stock. However, due to the decreasing abundance of their natural prey caused by predatory human hunting and/or the fragmentation of the natural habitat, wild carnivores can and will attack domestic species 33. This observation is valid for the present study, as the caatinga biome has suffered severe anthropogenic impacts, and native carnivores have lost access to considerable extensions of their former habitat, and consequently, their hunting territories. Conflicts between the human owners of domestic animals and predators have almost certainly occurred ever since animals were first domesticated 16 or plantings could be damaged 15. Hunting for animal control purposes in the region studied here was largely directed towards reptiles, principally serpents. Among all of the representatives of the herpetofauna, serpents are historically the most hated - although they can simultaneously inspire great curiosity 34,35. Many of the serpent species hunted by members of the study community were not poisonous, but were killed because of human fears or simple aversion. Conclusion Subsistence hunting in the study region is principally directed towards birds and mammals, which represent alternative sources of protein for local human populations. Hunting for pest control is principally directed towards reptiles (which are considered dangerous or loathsome) and these animals are indiscriminately killed whether they are poisonous or not. The game animals are captured or killed using wide spectrum of hunting strategies, but fire arms are most commonly employed. Hunting activities are very common throughout all of Brazil (even though they are known to be illegal) and are clearly associated with cultural factors - and additional studies will be needed to evaluate the degree of hunting pressure focused on the most sought-after species.
