东南亚森林的普遍开花事件可能是热带生物学中最壮观的现象。GF事件以多年为间隔发生。在GF中，大多数龙脑果属植物和许多其他科的植物大量开花和结果，这些物种和植物除了在GF事件期间外很少开花。GF是独一无二的，因为它可以发生在数千公里之外，涉及代表不同家族和生命形式的数百种植物。它还涉及到严格的桅杆结实。多面手种子捕食者的满足一直被认为是GF的主要力量。然而，最近的观察表明，形成GF的可能是几个选择性因素，而不是单一的主要因素。除了多面手捕食者的满足感外，授粉的促进可能是选择的因素之一，因为许多物种的同步开花通过迁徙和种群增长导致传粉者活动的增加。虽然为更好地建立苗木而进行的环境预测也可能涉及到环境预测，但目前还没有报道支持这一想法的田间数据。长期监测和进一步了解森林对于保护东南亚这一独特而多样的热带森林至关重要，特别是在全球气候变化期。《伦敦林尼安学会》，《林尼安学会生物杂志》，2002年，75,233-247页。
The general flowering (GF) events of forests in south-east Asia are perhaps the most spectacular phenomena in tropical biology. GF events occur at multiyear intervals. In GF, most dipterocarp species and many plants of other families come into flower and set fruit massively; these species and plants rarely flower except during GF events. GF is unique, because it can occur over thousands of kilometers and involve hundreds of plant species representing diverse families and lifeforms. It also involves strict mast fruiting. Satiation of generalist seed predators has been considered a primary force for GF. However, recent observations indicate that several selective agents rather than a single major factor may shape GF. In addition to the satiation of generalist predators, promotion of pollination could be one of the selective factors for GF, since synchronized flowering of many species causes an increase in pollinator activity through immigration and population growth. Although environmental prediction for better establishment of seedlings may also be involved in GF, no field data have been reported to support this idea. Long-term monitoring and further understanding of GF are essential for the conservation of this unique and diverse tropical forest in south-east Asia, especially in a period of global climatic change. © 2002 The Linnean Society of London, Biological Journal of the Linnean Society, 2002, 75, 233–247.
