研究了梅花鹿(Cervusnippon Temminck)对山间矮化竹--油竹(Sasanipponica Makino Et Shibata)生物量和形态的影响。日本中部的大田原。调查是通过比较防鹿围栏内外的日本血吸虫进行的。围栏外日本血吸虫生物量减少(292.7 d·w·g/50×50 cm)和105.1 d·w·g·(-1)。上部叶长(内径118.9 mm，外径69.8 mm)变小，茎粗(内径2 mm，外径1.2 mm)变小，竹数变密(内径2 5 4/50×5 0 cm，外径6 2 2根)。在防鹿围栏被破坏后，围栏内的日本血吸虫也经历了类似的变化，即生物量减少，下一次冲刷时生物量小型化和致密化。
We investigated the browsing effect of sika deer (Cervusnippon Temminck) on the biomass and morphology of Sasanipponica Makino et Shibata, a dwarf bamboo, in Mt. Ohdaigahara, central Japan. The investigation was performed through comparison of S. nipponica inside and outside a deer-proof fence. The S. nipponica outside the fence decreased in biomass (292.7 d.w.g./50×50 cm inside and 105.1 d.w.g. outside in August 1994), became miniaturized in culm height (49.1 cm inside and 15.6 cm outside), decreased in top leaf length (118.9 mm inside and 69.8 mm outside) and in culm diameter (2.0 mm inside and 1.2 mm outside) and densified in culm number (254/50×50 cm inside and 622 outside). After the destruction of the deer-proof fence, S. nipponica inside the fence underwent similar changes, that is, biomass decrease, miniaturization and densification in the next flush.
