Abstract

Production of a young secondary successional plant community and an older mature stand were measured in the tropical forest of the Luquillo Mountains of Puerto Rico. Production of both communities was relatively low, probably because of limited solar energy input into the forest. Rate of wood production and rate of leaf and litter production of plant communities throughout the world were compared. Annuals have the highest rate of leaf and litter production, and often the highest rate of total production. Leaf and litter production is relatively uniform in perennial herb and grass, and tree communities. Rates of wood production by trees is similar throughout the world, but efficiency of wood production is higher in northerly latitudes. In areas where solar energy is limited, there may be a selective advantage in producing wood as efficiently as possible.
