Short dry spells in the wet season increase mortality of tropical pioneer seedlingsBettina M J Engelbrecht
Smithsonian Tropical Research Institute, Gamboa, P O Box 0843 03092, Panama, Republica de Panama
Oecologia 148:258-69. 2006
..Our data provide strong evidence that short dry spells in the wet season differentially affect seedling survivorship of pioneer species, and may therefore have important implications to seedling demography and community dynamics...
Interspecific variation in xylem vulnerability to cavitation among tropical tree and shrub speciesOmar R Lopez
