Abstract

Capturing wild animals is common for conservation, economic or research purposes. Understanding how capture itself affects lifetime fitness measures is often difficult because wild and captive populations live in very different environments and there is a need for long-term life-history data. Here, we show how wild capture influences reproduction in 2685 female Asian elephants () used in the timber industry in Myanmar. Wild-caught females demonstrated a consistent reduction in breeding success relative to captive-born females, with significantly lower lifetime reproduction probabilities, lower breeding probabilities at peak reproductive ages and a later age of first reproduction. Furthermore, these negative effects lasted for over a decade, and there was a significant influence on the next generation: wild-caught females had calves with reduced survival to age 5. Our results suggest that wild capture has long-term consequences for reproduction, which is important not only for elephants, but also for other species in captivity.

摘要

捕捉野生动物通常是为了保护、经济或研究目的。由于野生动物和圈养种群生活在非常不同的环境中,并且需要长期的生活史数据,因此了解捕捉本身如何影响终生适应度指标通常很困难。在这里,我们展示了野生捕获如何影响缅甸木材工业中使用的 2685 头亚洲雌性大象 () 的繁殖。与圈养出生的雌性相比,野生捕获的雌性在繁殖成功率方面表现出一致的降低,终生繁殖概率显著降低,在生殖高峰期的繁殖概率更低,首次繁殖的年龄也更晚。此外,这些负面影响持续了十多年,并且对下一代有重大影响:野生捕获的雌性所生的幼仔在 5 岁时的存活率降低。我们的结果表明,野生捕获对繁殖有长期影响,这不仅对大象很重要,对圈养的其他物种也很重要。
