沙捞越的双子果混交林是世界上最丰富的热带雨林之一，仅在52公顷的面积内就有近1200种已知的树木(见Condit el al。2000)。我们不难想象，生殖系统，从开花到授粉和种子传播，在维持植物丰富的多样性方面起着至关重要的作用。然而，在东南亚热带雨林的社区层面上探索这一主题的研究相对较少。该地区的热带雨林也以社区中普遍存在的开花或群花现象而闻名(Ashton等人。1988年；阿帕纳1993年)。80%以上的树种开花周期长达6个月，开花间隔为2~10年，平均每4~5年开花1次。在一般的开花中，如此多的物种在如此短的时间内开花，以至于在一段时间内不可避免地出现授粉者短缺。有效的传粉者必须提供能够迅速满足数百万朵花和数百个物种需求的种群。此前，东南亚的热带雨林被认为全年都存在稳定、温暖、潮湿的气候。然而，最近发现，该地区的降雨量逐月变化，并具有各种长期节律(Inoue和Nakamura 1990；Inoue等人)。1993年)。在这些重复的周期中，最主要的周期每4到5年发生一次。其原因被称为厄尔尼诺-南方涛动(ENSO)。这段相对干燥的时期可能会持续几到10个月。早期的一种假设是干旱引发了
The mixed dipterocarp forests in Sarawak are among the richest tropical rain forests in the world with almost 1200 species of trees known in an area of only 52 hectares (see Condit el al. 2000). We can easily imagine that the reproductive system, from flowering through pollination and seed dispersal, plays a crucial role in maintaining the rich diversity of plants. However, relatively little study has explored this topic at the community level in the tropical rain forests of Southeast Asia.Tropical rain forests in this region are also known for the general flowering or mass-flowering phenomenon in the community (Ashton et al. 1988; Appanah 1993). More than 80% of the canopy trees species bloom during a period of up to 6 months at irregular intervals of 2 to 10 years, with a mean of once every 4 to 5 years. In a general flowering, or GF, so many species bloom in such a short period that a pollinator shortage inevitably occurs for some length of time. Effective pollinators must provide populations that can quickly meet the needs of millions of flowers and hundreds of species. Previously, tropical rain forests in Southeast Asia were believed to exist in a stable, warm, humid climate throughout the year. However, it has recently been found that rainfall in this region changes from month to month, and with various long-term rhythms (Inoue and Nakamura 1990; Inoue et al. 1993). Among these repeated cycles, the most dominant occurs every 4 to 5 years. Its cause is known as the El Nino-Southern Oscillation (ENSO). This relatively dry period may last for a few to 10 months. An early hypothesis was that drought triggered general
