在世界各地，特别是在社会经济条件差的农村社区，狩猎野生动物仍然是一种常见的活动。为了研究哺乳动物的狩猎模式，本研究以位于巴西半干旱地区的一个农村社区为模型，测试感知丰度、活动期（白天或夜间）和动物生物量等变量是否会影响哺乳动物分类群的消费潜力。在这项研究中，除了使用其他视觉刺激和自由列表外，还使用了清单/访谈技术，使用了32张在该地区记录的哺乳动物照片和2张在该地区没有出现的物种作为“对照”物种的照片。除了“对照”物种外，照片中的所有物种都被认为是在该地区出现的。14种物种被认为是当地最受猎杀的物种。被引用为被猎杀最多的物种的平均感知丰度高于被猎杀最少的物种。然而，一个物种的狩猎和当地感知的丰度之间没有显著的关系。白天和夜间活动物种的狩猎压力无显著差异，动物生物量与狩猎压力无显著关系。我们的研究结果表明，感知丰度是选择资源动物的一个重要因素，但其他因素，如预期用途、肉类风味和狩猎脆弱性等，可能会影响一个物种的潜在用途。
The hunting of wild animals remains a common activity in various parts of the world, especially in rural communities with poor socioeconomic conditions. To investigate patterns of mammal hunting, this study adopted a rural community located in semiarid Brazil as a model to test whether variables such as perceived abundance, activity period (day or night) and animal biomass could influence the consumption potential of mammal taxa. For this study, a checklist/interview technique using 32 photographs of mammals recorded in the region and two photographs of species that did not occur in the region, which acted as "control'' species, was used, in addition to other visual stimuli and free lists. All species presented in the photographs, with the exception of the "control'' species, were recognized as occurring in the region. Fourteen species were cited as being those most hunted locally. The species cited as most hunted had an average perceived abundance higher than the group of the least-hunted species. However, there was no significant relationship between hunting of a species and its locally perceived abundance. No significant difference in hunting pressure between diurnal and nocturnal species was found, nor was a relationship between animal biomass and hunting pressure observed. Our findings suggest that perceived abundance is an important factor for choosing a resource fauna, but other factors such as intended use, meat flavor and vulnerability to hunting, among others, may influence the potential use of a species.
