RESUMO
BACKGROUND: Hunting is a vital means of obtaining animal in various human populations. Hunters rely on their knowledge of species ecology and behavior to develop and employ hunting techniques and increase their chances of success. The comparison of the hunting practices of different human societies can shed light on the sustainability of hunting and the impact it has on species' populations. In this study, we examine and compare the techniques, modalities, and baits used by urban and rural hunters in Rondônia, a state in southwestern Amazonia, Brazil. We expected that rural hunters would use these elements and have greater knowledge when compared to urban hunters. We also expect that the use of specific hunting techniques and modalities will have greater selectivity and specificity of capture for rural hunters and that this knowledge will differ between groups. METHODS: We conducted 106 semi-structured interviews with rural and urban hunters from October 2018 to February 2020. We analyzed the data using PERMANOVA and Network analyses to compare and contrast the hunting practices of each group. RESULTS: We recorded four main hunting techniques divided into ten modalities with three techniques and seven modalities being the preferred choices among hunters. Waiting for at a Fruit Tree was cited as the primary technique employed by hunters living in urban and rural areas indicated. While the techniques and modalities were similar among hunters, the composition of species targeted and baits used differed between groups. Our network approach showed that modularity in urban areas was numerically lower than in rural areas. All species had one to more techniques associated with their capture. CONCLUSIONS: Hunters living in urban and rural environments showed high similarity in their practices, probably due to sharing similar environments to hunt containing similar species, as well as targeting preferably the same species.

Strategies that integrate conservation and development objectives are increasingly common, albeit still controversial, at the global scale. There are information gaps regarding their overall reach and sustainability through an integral assessment approach. Therefore, the objectives of this study were: 1) to design a Methodological Framework of Sustainability Evaluation (MFSE) that could be applied to the assessment of conservation and development strategies; and 2) to apply this MFSE in an empirical exercise with management units for wildlife conservation (UMAs, by its Spanish acronym), a major environmental policy in Mexico. The UMAs confer legal rights to landowners for the exploitation of wildlife and protection of ecosystems. The MFSE had five hierarchical levels (three sustainability dimensions, general and specific criteria, indicators and metrics), which are grouped into a Sustainability Index (SI). Data was collected from official databases, structured interviews with official managers and landowners, and field observations in six UMAs in Tabasco, Mexico. According to the findings, the SI in the social dimension showed the highest values, followed by the environmental and economic dimensions. The key aspects for sustainability in the six UMAs are: 1) local governance norms, 2) active participation and interinstitutional linkage, 3) capacity for initial economic investment and long-term vision and 4) project liability and appropriation from their design. Free-ranging and intensive UMAs pose different objectives, since the former are focused on the management and conservation of ecosystems where the species of interest are found, while the latter are focused on species-based management, mostly those of economic interest. For this reason, they may require separate governmental appraisal as different management systems.
