Rainfall effects on algae-dominated conditions.

General linear model for the effects of bromeliad volume, rainfall scenario, litter diversity and the interaction between rainfall and litter diversity on the occurrence of algae-dominated conditions. Algae-dominated ecosystems were defined as those which water contained more than 80 μg chlorophyll-a L-1. Rainfall scenarios Ambient, Medium clustering (MC), Medium amplitude (MA), High clustering (HC) and High amplitude (HA) are described in the main text. Significant values are presented in bold numbers (P<0.05).
