The table below summarizes our current research on living populations of plants and insects for scientific investigations. The live specimens exported from P.N. Corcovado form only a part of our system, which is available for comparative studies to any student or researcher in the world. The detailed studies here greatly enhance what we can learn in the field. Eventually the combination of laboratory, greenhouse, and field studies will give us a deep understanding of how this system maintains its structure and diversity in a place like Sirena Station, Corcovado National Park, Costa Rica. With this understanding I hope we can provide insights that will be of general use in managing the biodiversity of rainforest parks in the neotropics.
