狩猎是生物多样性丧失的主要驱动力，但缺乏对狩猎导致的降水的系统大规模估计。我们综合了176项研究，以量化热带地区狩猎导致的哺乳动物和鸟类数量的下降。与未狩猎地区相比，狩猎地区的鸟类和哺乳动物数量分别下降了58%(25%至76%)和83%(72%至90%)。鸟类和哺乳动物种群在距离猎人接入点(道路和居民点)7至40公里的范围内枯竭。此外，在可以交易野肉的主要城镇交通便利的地区，狩猎压力更大。保护区外的哺乳动物种群密度较低，特别是因为商业狩猎。迫切需要在受保护和未受保护的热带生态系统中可持续地管理野肉狩猎的战略，以避免进一步的违约。
Hunting is a major driver of biodiversity loss, but a systematic large-scale estimate of hunting-induced defaunation is lacking. We synthesized 176 studies to quantify hunting-induced declines of mammal and bird populations across the tropics. Bird and mammal abundances declined by 58% (25 to 76%) and by 83% (72 to 90%) in hunted compared with unhunted areas. Bird and mammal populations were depleted within 7 and 40 kilometers from hunters' access points (roads and settlements). Additionally, hunting pressure was higher in areas with better accessibility to major towns where wild meat could be traded. Mammal population densities were lower outside protected areas, particularly because of commercial hunting. Strategies to sustainably manage wildmeat hunting in both protected and unprotected tropical ecosystems are urgently needed to avoid further defaunation.
