摘要： 啮齿动物种子搬运行为对植物种群的更新和扩散具有重要意义。为探讨喀斯特微生境和种子大小对啮齿动物搬运行为的影响,2019年9—10月在单性木兰Kmeria septentrionalis和青冈栎Cyclobalanopsis glauca种子成熟期,将上述2种不同大小的植物种子同时摆放在4种不同的喀斯特微生境中(石洞、石槽、石面和土面),比较啮齿动物对不同微生境种子的搬运率差异。结果表明单性木兰种子和青冈栎种子间的搬运率呈极显著差异(Z=-21.902, P＜0.001),且啮齿动物更偏好搬运体积更小的单性木兰种子(93.56%±0.99% vs 7.41%±0.65%)。相同微生境中单性木兰种子和青冈栎种子间的搬运率都呈极显著差异(P＜0.001),其中,石洞(53.41%±3.60%)、石槽(51.31%±3.66%)和石面(49.19%±3.59%)3种微生境中的种子搬运率都高于土面(45.37%±3.59%)微生境。微生境和种子大小都是影响啮齿动物对单性木兰和青冈栎种子搬运的重要因素。啮齿动物对植物种子的搬运行为是喀斯特微生境和种子大小共同作用的结果。

Abstract: Seed removal behavior of rodents is of great significance to the regeneration and diffusion of plant population. The seeds of Kmeria septentrionalis and Cyclobalanopsis glauca with different sizes were placed in four karst microhabitats (stone cavern, stone groove, stone surface, and soil surface) from September to October, 2019.The differences of seed removal rate in different microhabitats were compared to explore the effects of karst microhabitat and seed size on rodent removal behavior. The results showed that there was a significant difference in the removal rate between the seeds of K. septentrionalis and C. glauca (Z=-21.902, P<0.001), and rodents preferred to remove the seeds with smaller volume (93.56%±0.99% vs 7.41%±0.65%). The removal rates of K. septentrionalis were significantly different from those of C. glauca in all same microhabitats (P<0.001), and the average seed removal rate in the microhabitats of stone cave (53.41%±3.60%), stone groove (51.31%±3.66%) and stone surface (49.19%±3.59%) were higher than that of soil surface microhabitat (45.37%±3.59%). Microhabitat and seed size are important factors that affect the seed removal of rodents, and the results show that the removal behavior of rodents to plant seeds is the result of the interaction of karst microhabitat and seed size.

Key words: Kmeria septentrionalis, Cyclobalanopsis glauca, seed removal, rodents, sympatry, karst microhabitat
