Mast fruiting and ENSO cycles - Does the cue betray a cause?

Evidence is mounting that flowering by the mast-fruiting Dipterocarpaceae in Southeast Asia is triggered by ENSO events such that seeds are dispersed at the end of ENSO droughts. These droughts induce substantial defoliation and mortality of canopy trees, producing a favorable environment for seedli...
