| 英文摘要 | Mast seeding is a common phenomenon, and has important effects on seed dispersal and hoarding by animals. at population level, the predator satiation hypothesis proposes that the satiating effect of a large amount of seeds on a relatively small number of predators benefits seed survival in mast-seeding years. however, the effect of mast seeding on the scatter-hoarding of rodents at the individual level is largely unknown. in this study, we investigated the effects of seed abundance (by simulating mast seeding and non-mast seeding) on the removal, consumption and scatter-hoarding of seeds of camellia oleifera (theaceae) by edward's rat leopoldamys edwardsi (muridae) in seminatural enclosures in southwest china. we wanted to test the masting-enhanced hoarding hypothesis, which suggests that rodents tend to scatter-hoard more seeds in mast-seeding years in order to occupy more food resources. our results indicate that l. edwardsi tended to disperse and scatter-hoard more seeds of c. oleifera per night with increasing seed abundance, and to eat less seeds per night when there was a high level of seed abundance in the enclosure experiments. these results support the masting-enhanced hoarding hypothesis. this capacity of rodents may be an evolutionary adaptation to the mast-seeding phenomenon. our results suggest that mast seeding benefits forest regeneration not only through the predator satiation effect at the population level, but also through increased hoarding by animals at the individual level. |
