Extract

Mathematical models predict that a nuclear war could cause widespread reductions in light intensity and temperature. To assess the possible impact of these reductions on lowland tropical rain-forests, we exposed seedlings of three species of the family Moraceae to various combinations of day and night conditions under reduced light. The species represent three stages in tropical rain-forest succession: Cecropia obtusifolia is an early-successional pioneer, Trichospermum mexicanum is a mid-successional tree, and Brosimum alicastrum is a late-successional tree of mature-phase forests.
