| Popis: | Herbivores can sometimes benefit the plants they consume. We investigated the interaction between an herbivore species, the Taiwan field vole (Microtus kikuchii), and its major food plant, the Yushan cane (Yushania niitakayamensis) of alpine meadows. We observed consumption of Yushan canes by voles in the field and laboratory, performed 2 field manipulative experiments and 2 laboratory cafeteria feeding experiments, and carried out chemical analyses on different Yushan cane parts to test 2 hypotheses: Taiwan field voles feed preferentially on certain Yushan cane parts due to their different chemical constituents, which vary with season; and herbivory by the Taiwan field vole has positive effects on fitness of Yushan cane. Our results showed that, although Taiwan field voles could exert a strong herbivorous pressure on Yushan canes through their near year-round preference for feeding on Yushan cane leaves, the presence of Taiwan field voles actually increases the emergence of Yushan cane shoots ov... |
