Use of wild vertebrates for consumption and bushmeat trade in Brazil: a review.

BACKGROUND: Bushmeat is a resource exploited by thousands of people around the world, especially in tropical and neotropical regions, constituting an important source of protein and income. But what is known, so far, about the consumption and trade of wild vertebrate meat (hereinafter "bushmeat") in a megadiverse country like Brazil? This question was answered through a systematic survey of publications on the consumption and trade of wild vertebrate meat made in Brazil between 2011 and 2021. METHODS: We selected 63 scientific articles available on "Google Scholar," "Science Direct," "Scopus," " Web of Science" and "Portal de Periódico da CAPES." The articles were categorized as: exclusive to (1) consumption or (2) bushmeat trade, totals of 54 and three articles, respectively; both (3) consumption and trade bushmeat, totaling six articles. We applied a nonparametric Spearman's correlation analysis to verify the association between the number of papers and the species richness of wild vertebrates cited for consumption by Brazilian state. RESULTS: The results revealed that the publications were concentrated in the Northeast (36), North (26) and Southeast (1) regions, distributed across 16 states of the federation. These data reinforce the need for more researches in states and other regions of the country. Our research hypothesis was confirmed, since the richness of species cited for meat consumption was positively associated with the amount of work carried out by the states of the federation. We identified a total of 321 species of wild vertebrates mentioned in the categories involving the consumption of bushmeat. We had a greater bird species richness mentioned for consumption (170) to the detriment of mammals (107), reptiles (40) and amphibians (4). Furthermore, in the articles involving the bushmeat trade categories we had 57 species of vertebrates mentioned, with mammals being the most representative in terms of species richness (29), to the detriment of birds (20) and reptiles (8). These data reinforce that birds and mammals have been the groups most used both for consumption and trade in bushmeat in the country's regions, and it is necessary to mitigate the hunting exploitation of these groups. We recorded that socioeconomic, biological, environmental and sociocultural factors were the most cited predictors of the consumption and trade of bushmeat in the articles. We identified that the bushmeat trade chain is dynamic and ramified, made up of several actors, including specialized and diversified hunters, intermediaries, market sellers, market vendors, restaurant owners and final customers. Public markets and open-air fairs were the most cited places for buying and selling wild meat in commerce. CONCLUSIONS: In general, our results indicate that we have made significant advances in publications on the consumption and trade of bushmeat in Brazil over the last few years. However, we highlight the need to better understand the patterns of consumption and trade of bushmeat in different regions of the country, as well as the factors associated with the dynamics of the trade chain and uses of wildlife by local communities. We emphasized that a multidimensional understanding of hunting activities is important to face socio-ecological problems and improve the conservation of target species which have continually been explored for uses by populations in different regions of the world.

Water spirits within the fishers' worldview: implications for fishing management in Northeast Brazil.

BACKGROUND: Historically, aquatic environments are linked to the worldview of many local people, where there is an interconnection between the natural world, the supernatural, and the social organization. In this study, we provided a discussion on how the supernatural beings that inhabit the freshwater systems interact with artisanal fishers and fishing resources in the riverine community of Parnaíba River middle course, in Mid North of Northeast Brazil. We also provided the implications of these interactions on the fisher's behaviors and how the acculturation process (e.g., introduction of new religions) can affect the fishers' worldview. METHOD: The selection of participants was done through intentional sampling. The content qualitative analysis was carried out to interpret the data from semi-structured interviews with 29 artisanal fishers. RESULTS: The mythical representations that inhabit the aquatic environments in the surveyed area were as follows: Mãe d' água, Cabeça de cuia, Muleque d'água, Visage, Piratinga, Sucuiuiu, and Luz e Arco-íris. These beings have distinctions regarding the form and attributions and can be associated with seasonality (temporal markers) and specific habitats (spatial markers). The respect and fear feeling of the mythical beings were striking among the fishers interviewed. For instance, we have record offering practices in order to obtain protection and success during the fisheries. These practices suggest that there may be local conservationist habits in fisheries management. However, the advancement of urbanization and the introduction of new religions that deny the existence of mythical entities are factors that can generate the acculturation process among the fishers. CONCLUSIONS: It is therefore necessary to carry out more studies in the surveyed area in order to evaluate the existence of possible patterns in the relationship between fisher and mythical beings. This information could confirm the role of mythical beings as environmental regulators. Consequently, it could be considered in the conservationist policies of fishery resources, reinforcing the importance of local knowledge and cultural factors for fishing management approaches.
