人们普遍认为，落叶覆盖了种子，这可能有利于种子的生存，但尚不清楚落叶是否以不同的方式促进大小不同的植物种子的生存。在这项研究中，我们研究了中国秦岭山区不同水平的凋落物覆盖对小种子油松和大种子华山松种子捕食和觅食/储藏的影响。我们的结果表明，落叶层未能保护华山松种子不被小型啮齿类动物吃掉，但却提高了油松种子的存活率。油松在原地被吃掉，而更多的华山松种子在高落叶覆盖率的地块被吃掉。因此，我们认为落叶层影响中国秦岭山区大小松树种子的存活率和捕食率。
It is generally accepted that leaf litter covers seeds, which may be beneficial for their survival, but it is unclear whether leaf litter contributes in different ways to the survival of plant seeds with contrasting sizes. In this study, we examined the effect of different levels of leaf litter coverage on seed predation and foraging/caching for small-seeded Pinus tabulaeformis and large-seeded Pinus armandii in the Qinling Mountains, China. Our results showed that leaf litter failed to protect P. armandii seeds from being removed by small rodents, whereas it improved seed survival for P. tabulaeformis. P. tabulaeformis were eaten in situ, whereas more P. armandii seeds were eaten in the high leaf litter coverage plots. Therefore, we propose that leaf litter affects the survival and predation rates for large and small Pinus seeds in the Qinling Mountains, China.
