The proposed research will investigate adaptation in a group            of plant species very common throughout the Old and New World                   tropics.  Studies will focus on a group of closely related                      species that live in slightly different habitats within a single                tropical rainforest in Mexico.  The experiments, including field,               greenhouse, and laboratory studies, will test several predictions               based on the general hypothesis that success in disturbed                       habitats requires responses that tend to maximize the capture and               utilization of light, water, and nutrients, while success in                    shady habitats depends on conservative responses that minimize                  the prospects for critical shortages of these resources.  Results               of these experiments should be useful both in answering general                 questions about how evolution shapes species for different                      habitats and in establishing criteria for plant success in                      disturbed and undisturbed rainforest habitats.  Though the                      proposed research is basic in its orientation, it should yield                  information with short-term applicability.  Tropical rainforests                are important both economically and culturally, but rainforest                  destruction is proceeding at a high rate.  At present, rainforest               biology is too poorly understood for managers to design effective               reforestation techniques and to implement programs of rainforest                resource utilization that preserve the integrity and                            functionality of the forest.  The proposed research, by focusing                on the mechanisms that allow plants to grow in disturbed and                    undisturbed habitats, will begin to give managers the necessary                 background.
