Tropical Root

Ecology & Evolution

Laboratory

Root systems are an important part of plants. They provide physical support, access to water, nutrients, and habitat for unique symbiotic associations necessary for plant survival. Their function can add up to 40% of the total productivity of a forest and surpass the return of nutrients to the soil when compared to aboveground organs.


The research at the TREE Lab focuses on two main topics: describe the diversity of root adaptations in vascular plants form a morphological, anatomical and functional perspective, and explore the evolutionary pathways that allow root systems to diversify and adapt to contrasting habitats. Our goal is to include roots as a central component in ecology and make root ecology a stand-alone field in terrestrial ecology.

Our lab employs a holistic approach, integrating fieldwork with modern lab techniques. We work with molecular tools that describe the microbial communities associated with roots, microscopy tools to describe the internal tissue in roots, and image analysis to describe the morphology of root systems. In addition, we use phylogenetic approaches to understand the evolutionary mechanisms that explain the current diversity in root form, function and symbiotic relationships.


Our exploratory work requires trips to different ecosystems with an emphasis on tropical areas. Current projects include sampling in Amazonian forests, mangrove areas in South Florida and the use of botanical collections in the US and abroad. 

Principal investigator

The TREE Lab is managed by Dr. Oscar J. Valverde-Barrantes, plant ecologist and assistant professor at Florida International University. His goal is for the lab to become a catalyst for the development of tropical root research in the United States. He enjoys working with the natural abundance of tropical forests to explore new theories and advance the field of plant ecology.

FIU courses

Members of the TREE Lab teach several courses at Florida International University: Plant Ecology, Wetland Ecology and Plant Morphology and Evolution. We like to make the most of our environment and take regular field trips to the Everglades and botanical gardens in and around Miami.

ICTB at The Kampong

Located at The Kampong (the historical estate of plant explorer Dr. David Fairchild and National Tropical Botanical Garden in Coconut Grove, Miami) FIU has launched a brand new facility: The International Center for Tropical Botany. Together with other faculty from the Department of Biological Sciences and an international network of collaborating researchers and institutions, the TREE Lab is committed to develop international research, education and outreach programs to train the next generation of botanists. With support from the Batchelor Foundation and the William R. Kenan Jr. Charitable Trust, we are taking the National Tropical Botanical Garden and Dr. Fairchild's legacy to new heights.
