摘　　要：为探究食果动物取食行为与植物种子间相互联系,本文以亚热带森林种子特征差异较大的优势树种甜槠(Castanopsis eyrei)和云山青冈(Cyclobalanopsis sessilifolia)种子为研究对象,探究食果动物对不同类型种子单一品质(完整、发霉和残缺)混合释放和单一类型种子不同品质混合释放扩散行为的影响。结果表明:(1)完整品质种子被搬运距离较远,云山青冈种子搬运后取食距离和贮藏距离均高于甜槠种子,符合大种子假说;(2)种子类型混合释放和种子品质混合释放扩散距离有差异,表明种子品质能影响动物扩散行为。To explore the relationship between frugivores feeding behavior and plant seeds,this study focuses on the dominant tree species of subtropical forests,Castanopsis eyrei and Cyclobalanopsis sessilifolia,which have different seed characteristics.The effects of frugivores on the mixed release of single quality(intact,moldy and broken)of different types of seeds and the mixed release and diffusion behavior of different quality of single type of seeds were investigated.The results showed that:(1)The intact quality seeds were removal far away,and the feeding distance and storage distance of C.sessilifolia seeds were higher than those of C.eyrei seeds,which was consistent with the large seed hypothesis.(2)The diffusion distance of mixed release of seed type and mixed release of seed quality was different,indicating that seed quality could affect animal diffusion behavior.
