摘要:

鼠类-植物种子互作关系是森林生态系统研究的重点之一, 对森林生态系统结构和功能维持具有重要意义。许多研究关注了鼠类的行为习性、种群动态、群落结构、种间合作与竞争以及植物的种子特征和环境因素等对鼠类与植物种子取食和传播关系的影响。然而, 从种群内个体差异的角度探讨鼠类种子传播作用的研究较少, 鼠类种内特征(尤其是鼠类个性)为理解种子命运的巨大变化提供了另一种方法。近年来, 动物的个性及其生态效应逐渐受到关注, 但是将动物的个性与种子传播等生态服务联系起来的理论和研究案例较为少见, 妨碍了人们对动物个性如何影响种子传播进而影响植物更新机制的理解。本文结合近年来动物个性研究进展, 初步阐述了鼠类个性研究现状; 介绍了测量鼠类个性的常用方法(如旷场实验、出现实验和洞板实验等)以及这些方法测量了鼠类哪些个性; 着重讨论了鼠类个性对植物种子传播的影响, 强调了鼠类单一个性(如勇敢性、活跃性和探索性等)与种子传播的关系; 总结了鼠类个性介导种子传播的生态、进化和保护意义。在今后的研究中要设计适合的野生鼠个性测量方法, 长期监测不同个性鼠类与种子传播的关系, 实现理论预测和实证研究的整合。

Abstract

Background & Aims:The relationship between rodents and seeds represents an integral component of the structure and functional maintenance of forest ecosystems. Previous literature has characterized how this relationship may influence aspects of rodent behavior, population dynamics, community structures, interspecific cooperation and competition, plant seed characteristics, and environmental factors. However, there is a dearth of literature examining the effects of intraspecific variation of rodents on seed dispersal. We aim to review how intraspecific traits (especially personalities) of rodents affect seed dispersal, which it may present an important alternative path towards understanding the wide variation of seed fates.

Progress: Empirical investigations have supported the notion that animal personalities are one important feature of intraspecific variation between animals. Despite this, few studies have aimed to test the ecological repercussions (i.e. seed dispersal) that result from varying rodent personalities. This presents a major limitation, as it creates a significant gap in our understanding of how rodent personalities influence seed dispersal and plant regeneration mechanisms. In order to better understand this gap study, we introduce the progress in the research of rodent personality and then introduce the common methods for personality measurements of rodents (e.g. open-field test, emergence test and hole-board test). We highlight the effect of rodent personality on seed dispersal and specifically point out the relationship between the single personality (not behavioral syndromes) of rodents (e.g. boldness, activity and exploration) and seed dispersal. Finally, we summarize the ecological, evolutionary, and conservation consequences of rodent personality in mediating seed dispersal.

Going Forward: More research is needed to design both suitable methods to evaluate personality characteristics of wild rodents, as well as to develop long-term monitoring techniques that would allow for longitudinal investigation of the relationships between personality variation in rodents and seed dispersal.
