Research Interests

Current Research

By comparing the distribution of vein density through different forest habitats I want to test the possible application of this leaf trait to the fossil record as proxy of forest stratification.

During my M.Sc. I plan to collect canopy and understorey leaves of different species from a temperate forest in Maryland (Smithsonian Environmental Research Center) and a dry tropical forest in Panama. I will measure and compare the vein density distribution in these forests with the data previously collected in two Tropical rainforests in Panama (Sherman and Parque Metropolitano plots).

What is vein density?

The evolution of leaf vein density (a trait preserved on fossils) occurred during the Cretaceous. This trait is related to the ability of plants to do photosynthesis and to transpire and it is ecologically important because Angiosperms photosynthesis and transpiration are responsible for large amounts of precipitations in tropical forest ecosystems. The relation between vein density and the physiology of plants suggests that vein density differences among species could be related to different ecological strategies.
