摘要:

虎(Panthera tigris)和豹(P. pardus)作为食物链的顶级捕食者对维持生态系统结构与功能稳定性起到重要作用。强烈的人为干扰已导致亚洲虎和豹种群(以下简称虎豹)分布呈现破碎化状态, 探究二者之间的相互作用对缓解人类威胁和濒危物种保护具有重要意义。尽管虎豹竞争和共存研究已持续几十年, 但多局限于区域性种群, 缺乏系统性研究。本研究梳理了1976-2021年间36篇涉及虎豹竞争性相互作用研究的文献, 涵盖中国、俄罗斯、泰国、马来西亚、印度、尼泊尔、不丹共7个国家26个区域, 系统阐述了虎豹目前在亚洲的主要分布以及它们之间的干涉型和资源利用型竞争的主要表现形式, 并分析了猎物与干扰因素对虎豹竞争与共存的影响。本研究提出了5个可能影响种间作用的猎物构成情况, 强调了不同大小有蹄类猎物的丰富度和多度以及人为干扰的空间分布对虎豹区域竞争和共存的调控作用。现有研究显示虎豹的空间利用取决于本地的生境、猎物和干扰等因素。豹相对于虎具有更强的行为可塑性, 虎豹之间在空间、时间和营养生态位等维度权衡生态机会(如容易捕获的猎物)与冲突风险(人或竞争者带来的风险)来促进共存。目前虎豹相互作用研究存在严重的亚种和区域不平衡性, 未来研究重点应关注各种生物和非生物类因素对虎豹种间竞争类型和作用强度的调控方式以及调控的生态阈值效应。

Abstract

Background & Aim: As apex carnivores, tigers (Panthera tigris) and leopards (P. pardus) play critical roles in maintaining the structural and functional stability of Asian forest ecosystems. The populations and ranges of these two felids have declined due to human disturbance. To mitigate anthropogenic threats to endangered species in these ecosystems, it is essential that we understand how tigers and leopards interact. Although competition between tigers and leopards has been studied for several decades, most studies have taken place in the famous reserves like Nagarahole National Park and Chitwan National Park in South Asia, so it is unknown how their interactions differ elsewhere in their overlapping range. Here, we review 36 previous papers on competitive interactions between the two big cats from 1976 to 2021. We summarize the nature of both interference and exploitation competition between tigers and leopards in their current overlapping range, as well as how prey and human disturbance shapes this competition.
Review Results: We found that the most important factors affecting tiger-leopard competition and coexistence included species richness at various size classes of prey and also the spatial distribution of human disturbance. Local habitat, prey composition, and disturbance factors affect tiger-leopard interactions by shaping the trade-off between ecological opportunities (e.g., easy prey) and the risk of escalating conflict with humans and other competitors across spatial, temporal, and dietary niches.
Perspectives: There is currently a significant regional bias in the study of tiger-leopard competition and coexistence, with most research focusing on the overlapping range in South Asia and neglecting these in Northeast and Southeast Asia. To more fully understand how tigers and leopards interact, future research should occur longitudinally throughout their shared range, with a focus on multiple ecological niches and fine spatial scales. Research on the biotic and abiotic factors affecting tiger-leopard competition should aim to identify their ecological thresholds and the regulation mechanisms by which these factors affect the intensity and types of competition.
