Title: | 全球變變遷:長期生態學研究:福山森林生態系─動物傳播造成種子空間分布與密度變化對種子命運之影響(1/3) | Authors: | 李玲玲 | Keywords: | 福山;台灣獼猴;種子傳播;Fushan;Macaca cyclopis;seed dispersal | Issue Date: | 2004 | Publisher: | 臺北市:國立臺灣大學生態學與演化生物學研究所 | Abstract: | 本研究藉由追蹤福山試驗林台灣獼猴 取食果實種子之行為,記錄排遺與吐出種 子的地點與其微棲地、空間分布及排遺中 種子的密度,並以操弄實驗控制種子的密 度與空間分布,比較不同條件下種子活 存、被移除與掠食及萌發的比例與萌發後 成長的狀況,以檢驗獼猴傳播造成種子空 間分布與密度變化對種子命運之影響。初 步結果顯示不同性別年齡之獼猴在取食果 實種子速度、將種子吐在母樹下或帶離母 樹的比例有所差異。約有38%被吐出的種 子掉落在距母樹約30-70 公尺之處,另有 大部分的種子是被吐在休息地點。掉落在 森林中的種子其發芽率顯著高於掉落在開 闊地的種子,但種子是否掉落至母樹下或 非母樹下,或是以單顆或聚集的方式落 下,對發芽率並沒有顯著的影響。 To study the impact of seed dispersal by the Formosan macaques in affecting the spatial distribution and fates of seeds, we followed two troops of macaques at Fushan experimental forest and recorded their feeding behavior and locations where they defecate or spit out seeds. The microhabitat of the deposited seeds and feces were evaluated, and the densities of seeds spat out or in the feces were examined and followed for the fates of seeds. We also conducted manipulation experiments by setting seeds in forest versus in open area at different distance away from parent trees, with different densities and with or without the cover of macaques’ fecal material and compared the survival, removal, and germination rates of these seeds, and the growth of seedlings. Preliminary results indicated that macaques of different sexes and ages differed in their feeding rates and the ratio of seeds either dropped at or away from feeding trees. Approximately 38% of seeds were spat at feeding trees, the majority of the rest of seeds consumed by the macaques were dropped at the resting sites of macaques. Seeds dropped in the forest had significantly higher germination rates than those in open areas. However, no significant difference was found in the germination rates between seeds dropped under the same or different tree species, or between single seed or clumped seeds. |
