Scatter- and larder hoarding are the primary strategies of food-hoarding animals and have important implications for plant-animal interactions and plant recruitment. However, their origins and influencing factors have not been fully investigated across a wide range of taxa. Our systematic literature search amassed data for 183 seed-hoarding rodent species worldwide and tested relationships of seed-hoarding behaviours with phylogenetic signal, functional traits and environmental factors. We found that the evolution of hoarding strategies was not random in phylogeny, and scatter hoarding originated independently multiple times from larder hoarding. Rodents with higher encephalisation quotient (relative brain size), omnivorous diet (related to dependence on seeds) and inhabiting lower latitudes were disproportionately likely to scatter hoard. Despite body mass’s potential relationship with competition through food defence, it was associated with food-hoarding strategy only in a few families. Our results show the need to study the community and ecological context of food-hoarding behaviours.

啮齿动物分散和囤积行为的进化和生态模式

分散囤积和储藏室囤积是食物囤积动物的主要策略,对动植物相互作用和植物补充具有重要意义。然而,它们的起源和影响因素尚未在广泛的分类群中得到充分研究。我们系统的文献检索收集了全球 183 种种子囤积啮齿动物物种的数据,并测试了种子囤积行为与系统发育信号、功能性状和环境因素的关系。我们发现囤积策略的演变在系统发育中并不是随机的,分散囤积多次独立于储藏室囤积。具有较高脑化商(相对大脑大小)、杂食性饮食(与对种子的依赖有关)和居住在低纬度地区的啮齿动物极有可能分散囤积。尽管体重通过食物防御与竞争存在潜在关系,但仅在少数家庭中与食物囤积策略有关。我们的结果表明有必要研究食物囤积行为的社区和生态环境。
