Abstract Access to sophisticated hunting strategies increases in some political and economic contexts, such as during civil war episodes in Angola (Central Africa) in which there was a widespread distribution of automatic rifles to citizens. This facility favours the local people to slaughter larger animals, mainly during conflict gaps and in the post-war period. Herein, we conducted interviews with hunters to identify the hunting techniques used before, during and after the Angolan civil war in two different landscapes - savannah and forest. We collected information on techniques used by the hunter to approach, pursue and capture game species. Through a network approach and regression models we found that rifles introduced by the Angolan civil war magnify the spectrum of species caught from small-bodied to large-bodied species, and might induce a mammalian population abundance erosion. We also found a clear species-specific conjunct of hunting techniques, valuing the cost-benefit of each approach. The usage frequency of rifles was also higher in the savannah than in the forest. We reveal that changes over time for prey approximation and persecution techniques, which are possibly guided to attend the animal trade chain. Finally, these hunting technique changes has resulted in the predominance of individual hunting events with relatively low bushmeat shared between hunters, indicating a hunting pattern that contrasts with the historical hunting strategy based on collective expeditions. We can conclude that the shift in hunting techniques arising from the Angolan civil war induced a body-mediated decline in mammal diversity, causing their overwhelming annihilation.

从长矛到自动步枪：安哥拉内战期间作为哺乳动物消耗驱动器的狩猎技术的转变

摘要 在某些政治和经济背景下，获得复杂的狩猎策略的机会增加，例如在安哥拉（中非）的内战期间，自动步枪向公民广泛分发。该设施有利于当地人屠宰较大的动物，主要是在冲突期间和战后时期。在此，我们对猎人进行了采访，以确定安哥拉内战之前、期间和之后在两个不同的景观 - 热带草原和森林中使用的狩猎技术。我们收集了有关猎人接近、追捕和捕获猎物物种所使用技术的信息。通过网络方法和回归模型，我们发现安哥拉内战引入的步枪放大了从小型到大型物种捕获的物种范围，并可能导致哺乳动物种群数量减少。我们还发现了一个明确的特定物种的狩猎技术结合，评估了每种方法的成本效益。步枪在大草原的使用频率也高于森林。我们揭示了猎物逼近和迫害技术随时间的变化，这些技术可能被引导到动物贸易链中。最后，这些狩猎技术的变化导致个体狩猎事件占主导地位，猎人之间共享的丛林肉相对较少，表明这种狩猎模式与基于集体探险的历史狩猎策略形成鲜明对比。我们可以得出结论，安哥拉内战引起的狩猎技术的转变导致了哺乳动物多样性的身体介导的下降，导致它们被压倒性地灭绝。
