摘要: Dipterocarpaceae, the dominant family of Bornean canopy trees, display unusual reproductive strategy strict interspecific mast-fruiting. During 1986–99, more than 50 dipterocarp species dispersed seed only within a 1- to 2-month period every 3 4 years during El Nino–Southern Oscillation events. Synchronous production occurred across extensive areas and was essential for satiating predators. Logging dipterocarps reduced extent intensity these episodes exacerbated local Nino conditions. Viable seedling establishment have declined as result climate, logging, Since 1991, experienced recruitment failure national park, now surrounded by logged forest.
