摘要:

陆生食肉动物(食肉目哺乳动物, 以下简称食肉动物)作为食物链与营养级的高位物种对维持生态系统结构与功能稳定性起到重要作用。过度人类干扰已在全球范围内造成食肉动物种群数量剧烈下降和栖息地质量显著退化, 探究食肉动物的区域共存机制对理解生物群落构建、濒危物种保护与管理具有重要意义。本文通过梳理100余篇有关食肉动物在空间、时间和营养3个生态位维度上相互作用的研究, 分析了体型大小、猎物组成、种群结构、环境差异、人类干扰和气候变化等因素对食肉动物种间关系和区域共存的影响, 并对今后食肉动物区域共存研究中亟需解决的问题进行了展望。食肉动物通过生态位分离达到共存并没有单一的理论解释, 猎物、栖息地和人类干扰等因素可以调节食肉动物相互作用关系并直接或间接地影响共存, 共同适应在食肉动物区域共存中具重要作用。食肉动物区域共存是经过长期演化形成的相对稳定状态, 需要以动态的眼光去审视。要明晰生态位重叠与区域共存机制的区别与联系, 在理解生态位分离的基础上, 结合生活史、家域和行为等对食肉动物共存进行综合分析。

Abstract

Background & Aim: Carnivores play an important role in maintaining the structural and functional stability of ecosystems. Increasing anthropogenic pressure has resulted in dramatic population decline and habitat degradation of carnivores worldwide. Exploring regional coexistence mechanisms of carnivore populations is important to understand how mammal communities assemble, along with protecting and managing endangered species. This review summarizes the interactions of terrestrial carnivores along three dimensions (i.e., spatial, temporal and dietary), of their ecological niches, analyzing the influence of factors such as body size, prey composition, environmental difference, human disturbance and climate change on the coexistence of carnivores based on more than 100 related studies.
Review Results: We put forward the problems to be addressed for current study of carnivore coexistence. This study demonstrates that there is no single theoretical explanation for carnivore coexistence through niche separation. Prey, habitat and human disturbance may mediate the intensity of carnivore interactions and then influence their coexistence directly and indirectly. We also emphasize the critical role of co-adaptation for carnivore coexistence. Carnivore coexistence is a relatively stable state of long-term evolution, which needs to be examined dynamically.
Perspectives: We should correctly understand the differences and connections between niche overlap and coexistence. Besides niche separation, carnivores’ life history, movement and behavior should also be considered to interpret their coexistence.

Key words: carnivores, niche segregation, species coexistence, intraguild predation theory, interspecific relationship
