摘要

在这里,我们记录了在莫雷米野生动物保护区(博茨瓦纳奥卡万戈三角洲)东南边界附近的一个私人特许权中,狮子捕食幼象事件的直接后果。对胴体进行为期四周的监测,以评估脱缰和清道夫活动的模式。狮子是主要的消费者,在第一周内迅速消耗了大部分解剖区域,几乎没有证据表明早期鬣狗参与其中。鬣狗出现较晚,但对骨骼组合的影响不大,可能是由于生态系统中食物丰富。值得注意的是,足垫等软组织结构在一个月后仍然完好无损。这些观察结果对古人类学有影响,表明巨型动物尸体上的大块肉只有在对抗的食腐情景下才能被早期人类获取。此外,这些数据还提供了高生物量景观中食肉动物竞争和资源利用的生态学见解。

The Ecology of an Elephant Kill: Lion Defleshing of an African Elephant in the Okavango Delta (Botswana), and Limited Kleptoparasitic Opportunities for Meat-Eating Scavengers

Here, we document the immediate aftermath of a lion predation event on a juvenile elephant in a private concession near the southeastern border of the Moremi Game Reserve (Okavango delta, Botswana). The carcass was monitored over a four-week period to assess patterns of defleshing and scavenger activity. Lions were the primary consumers, rapidly defleshing most anatomical regions within the first week, with minimal evidence of early hyena involvement. Hyenas appeared later but had little impact on the bone assemblage, likely due to food abundance in the ecosystem. Remarkably, soft tissue structures like podal pads remained intact after a month. These observations have implications for paleoanthropology, suggesting that bulk meat from megafaunal carcasses would only have been accessible to early hominins under confrontational scavenging scenarios. Additionally, the data provide ecological insight into carnivore competition and resource use in high-biomass landscapes.
