Abstract

Seed dispersal is very important for the gene flow of plant populations and for maintaining the population structure Many fleshy-fruited plants cost energy to make fleshy or juicy arillate attracting effective seed dispersal frugivores arrive establish the mutualism relationship between the fleshy-fruit and frugivores In most of the subtropical and tropical rainforests more than 70% of the plant species bearing fleshy fruit Ficus spp can produce large amount of figs throughout the year make them the keystone resources of the tropical forest Many studies have found that the greater the crop size of the plant the higher the visitation rate and seed removal rate of frugivores which support the fruit crop size hypothesis However the fruit selection and visit duration of animals are affected by a number of factors such as the plant traits: nutritional value color and size of fruit and seed; Even by the traits or conditions of the birds themselves like sexuality degree of hunger the presence of competitor and predators In this study direct observation method was used to record the feeding behavior of the frugivores and the figs number in four Ficus species Also recorded the number of fruit dropping under the trees with seed traps I want to investigated the relationship between foraging strategies of frugivores and the fruiting strategies of Ficus species in Hengchun Tropical Botanical Garden discuss the influence of crop size and crop density on foraging performance including foraging group size and the feeding rate of frugivores And to understand the how frugivores exploit resource under the interaction of different factors The integration of the factors not only helps to clarify the interaction between frugivores and figs but also let us explore the frugivores’ indirectly impact on the regeneration of the forest and the community structure of plants in future explores
