| 中文摘要 | 土壇樹(Alangium salviifolium)是落葉樹種,它在乾季完成落葉、開花、結果、重新長葉的過程。花期為3月到4月,是鳥類和昆蟲的食物來源。這種樹的繁殖方式為同株異花授粉及異株異花授粉,授粉媒介為燕雀類如Dicaeum erythrorhynchos, Nectarinia zeylonica, N. asiatica以及Xylocopa屬蜜蜂。其果實初期為綠色,之後轉變為紫紅色,最後是黑色(肉質)。一些鳥類如Acridotheres tristis, Turdoides caudatus, Psittacula krameri會攝食這些肉質黑色果實,並且把種子帶離母樹。本研究顯示前述鳥類為土壇樹唯一的果實傳播媒介。 |
| 英文摘要 | Alangium salviifolium, a deciduous tree species, completes leaf shedding, flowering, fruiting and leaf flushing during the dry season. The flowering occurs during March-April; and the flowers facilitate foraging by birds and insects. The tree reproduces through geitonogamy and xenogamy. The flowers are pollinated by passerine birds such as Dicaeum erythrorhynchos, Nectarinia zeylonica and N. asiatica, and Xylocopa bees only. The fruit is green initially, purplish-red later and finally turn black and fleshy. Birds such as Acridotheres tristis, Turdoides caudatus and Psittacula krameri were found to feed on the black, fleshy fruits and drop the seeds away from the mother tree. As a result of our study, these birds have been found to be the sole seed dispersal agents of A. salviifolium. |
