Neotropical forests have the highest tree diversity on earth. While many studies focus on the maintenance of tropical tree diversity, relatively few study the processes that lead to diversification and in turn speciation.  Protium subserratum (Burseraceae) is an edaphic specialist with what appears to be diverging populations on white sand and terrace soil types.  My research is centered in the Peruvian Amazon and uses morphological measurements, population genetics, hand crosses, reciprocal transplants, common gardens and more to…


1)Test the morphological integrity and genetic structure of these different morphotypes


2)Examine the role of pollinators in limiting gene flow between morphotypes


3)Test for the existence of prezygotic intrinsic isolating factors between morphotypes


4)Test for the existence of postzygotic intrinsic isolating factors between morphotypes
