Conceptual model of seed bank input as a function of humidity-regulated dormancy onset under variable weather conditions. We hypothesize that there is a higher potential for seeds to respond to humidity fluctuations prior to dispersal when the seeds are held in the tree canopy compared with post-dispersal, when seeds fall to the soil surface, after which they may be removed to ants' nests or otherwise buried in soil or leaf litter after some period of time. Germination of non-dormant seed follows rainfall and dormant seeds accumulate in a seed bank.
