Phenological traits of fruiting and seed dispersal of Eurya japonica, a key species in fruit-bird interactions in lucidophyllous forests

Kominami Yohsuke , Manabe Tohru

ヒサカキは照葉樹林に広くみられる樹種であり，その果実が多様な鳥種に採食・散布されることから，その散布特性が多くの鳥散布性植物の散布時期・量に影響する可能性がある。ヒサカキが成熟果をつける時期は初秋から冬にかけてであり，鳥に採食・散布される時期も長期にわたる。この季節性は，散布者側の密度や選好性，植物側の果実特性や個体差によって生じると想定される。<br>　本研究では，ヒサカキ果実の消失 …

Classification of bird-dispersed plants by fruiting phenology, fruit size, and growth form in a primary lucidophyllous forest: an analysis, with implications for the conservation of fruit-bird interactions

… To understand the patterns of fruit-bird interactions and to identify species with significant roles that are irreplaceable in these interactions (key species), we classified plant types according to traits relating to frugivory by birds, and analyzed the relationships between plant types and frugivorous birds in a primary lucidophyllous forest in Japan. … At the 4-ha study site, 111 plant species were bird-dispersed and 15 common bird species were frugivorous. …
