Description:
Dipterocarpaceae, the dominant family of Bornean canopy trees, display the unusual reproductive strategy of strict interspecific mast-fruiting. During 1986-99, more than 50 dipterocarp species dispersed seed only within a 1- to 2-month period every 3 to 4 years during El Nino-Southern Oscillation events. Synchronous seed production occurred across extensive areas and was essential for satiating seed predators. Logging of dipterocarps reduced the extent and intensity of these reproductive episodes and exacerbated local El Nino conditions. Viable seed and seedling establishment have declined as a result of climate, logging, and predators. Since 1991, dipterocarps have experienced recruitment failure within a national park, now surrounded by logged forest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curran -- Caniago I -- Paoli -- Astianti -- Kusneti -- Leighton -- Nirarita -- Haeruman -- New York, N.Y. -- Science. 1999 Dec 10;286(5447):2184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA.
